Description

L'invention se rapporte à un dispositif d'accueil d'un pied ou d'une chaussure sur un engin de sport tel que, notamment, un engin de glisse.The invention relates to a device for receiving a foot or a shoe on a sports machine such as, in particular, a gliding machine.

De tels dispositifs sont utilisés pour la pratique du surf sur neige, ou snowboard, du ski sur neige, de la raquette à neige, ou autre.Such devices are used for snowboarding, snowboarding, snow skiing, snowshoeing, and the like.

Certains dispositifs selon l'art antérieur comprennent une assise, prévue pour accueillir le pied ou la chaussure, ainsi qu'un élément d'appui arrière, prévu pour supporter le bas de jambe d'un utilisateur. L'élément d'appui arrière est relié à l'assise, généralement au moyen d'une articulation, pour pouvoir être rabattu vers celle-ci. Cela réduit l'encombrement et facilite le rangement. Il est aussi prévu une butée qui limite le déploiement de l'élément d'appui arrière par rapport à l'assise.Some devices according to the prior art comprise a seat, designed to accommodate the foot or the shoe, and a rear support element, designed to support the lower leg of a user. The rear support element is connected to the seat, usually by means of a hinge, to be folded towards it. This reduces clutter and makes storage easier. There is also provided a stop which limits the deployment of the rear support element relative to the seat.

Ce cas de figure est fréquent en snowboard. Dans cette discipline l'utilisateur a les deux pieds retenus sur une même planche, et orientés dans une direction sensiblement transversale de la planche. Les sollicitations transversales sont donc localisées vers les pointes de pieds, ou vers les talons. Dans le cas de sollicitations vers les pointes de pieds, un élément d'appui arrière ne supporte pas ou peu de contraintes. Par contre, lors de sollicitations vers les talons, l'élément d'appui arrière supporte des contraintes qui peuvent être très élevées. Par voie de conséquence la butée les supporte aussi. Par exemple lors d'une prise de carre arrière, c'est-à-dire vers les talons, l'élément d'appui arrière transmet des impulsions arrière envoyées par le bas de jambe. Dans d'autres cas l'élément d'appui arrière renvoie à l'utilisateur des impulsions issues du sol. Ces impulsions transitent par la butée.This case is common in snowboarding. In this discipline the user has both feet retained on the same board, and oriented in a substantially transverse direction of the board. The transversal stresses are localized towards the tips of the feet, or towards the heels. In the case of solicitations to the toes of feet, a rear support element does not support or few constraints. By cons, during solicitations to the heels, the back support element supports constraints that can be very high. As a result the stop supports them too. For example when a rear edge, that is to say towards the heels, the rear support element transmits back pulses sent by the lower leg. In other cases the rear support element sends back to the user pulses from the ground. These pulses pass through the stop.

Afin de conférer à un dispositif d'accueil les caractéristiques mécaniques ad hoc, l'art antérieur a proposé diverses structures.In order to confer on an accommodation device the ad hoc mechanical characteristics, the prior art has proposed various structures.

Il est notamment connu qu'une assise comprenne un flasque latéral et un flasque médial reliés l'un à l'autre par une embase et un arceau. Bien entendu l'embase supporte la semelle de la chaussure, et l'arceau contourne le talon. L'élément d'appui arrière est articulé relativement à l'assise au niveau de la limite entre les flasques et l'arceau, en étant disposé en avant de ce dernier. Une butée est assujettie à l'élément d'appui arrière de façon à prendre appui sur l'arceau, lorsque le bas de jambe envoie des impulsions arrière. Cette structure éprouvée permet une conduite satisfaisante de la planche. Cependant, elle présente quelques inconvénients.It is notably known that a seat comprises a lateral flange and a medial flange connected to one another by a base and a bow. Of course, the base supports the sole of the shoe, and the arch circumvents the heel. The rear support member is articulated relative to the seat at the boundary between the flanges and the arch, being disposed in front of the latter. A stop is subject to the rear support element to bear on the hoop, when the lower leg sends backward pulses. This proven structure allows a satisfactory driving of the board. However, it has some disadvantages.

Tout d'abord le maintien du talon n'est pas optimal. Cela signifie que le talon n'est pas toujours maintenu avec le confort ou la précision qui convient, au moins pendant certaines phases de la conduite.First of all the maintenance of the heel is not optimal. This means that the heel is not always maintained with the comfort or precision that is appropriate, at least during certain phases of driving.

Dans les cas où l'élément d'appui arrière est relativement rigide, pour une conduite sportive par exemple, le contact entre la chaussure et l'élément d'appui arrière n'est pas uniforme. En d'autres termes, la chaussure n'épouse pas parfaitement la forme de l'élément d'appui arrière. Il s'ensuit une répartition irrégulière des pressions liées au contact de l'une sur l'autre, certaines parties de la chaussure étant trop comprimées, alors qu'au niveau d'autres parties subsiste un jeu.In cases where the rear support element is relatively rigid, for sports driving for example, the contact between the shoe and the rear support element is not uniform. In other words, the shoe does not perfectly fit the shape of the rear support element. This results in an uneven distribution of the pressures related to the contact of one over the other, some parts of the shoe being too compressed, while at the other parts remains a game.

Dans les cas où l'élément d'appui arrière est plus souple, pour une conduite plus sereine, le contact entre la chaussure et l'élément d'appui arrière est perturbé par l'action de l'arceau. Ce dernier est rigide, car il coopère avec la butée. De fait l'arceau renvoie des efforts ponctuels à la chaussure, par l'intermédiaire de la butée et de l'élément d'appui arrière, et parfois par l'intermédiaire du seul élément d'appui arrière, là où ce dernier vient directement en appui sur l'arceau.In cases where the rear support element is more flexible, for a more serene driving, the contact between the shoe and the rear support element is disturbed by the action of the hoop. The latter is rigid because it cooperates with the stop. In fact the arch returns sporadic efforts to the shoe, through the abutment and the rear support element, and sometimes through the only back support element, where the latter comes directly resting on the arch.

En conséquence il arrive, surtout en cas d'utilisation extrême ou prolongée, que la tenue du talon soit inconfortable ou imprécise. Cela nuit à la conduite.As a result it happens, especially in case of extreme or prolonged use, that the holding of the heel is uncomfortable or imprecise. It hurts driving.

Un autre inconvénient est la complexité de la structure. L'assise, avec son embase et son arceau, est une pièce en trois dimensions dont les formes la rendent délicate à fabriquer. Ensuite la structure selon cette première famille fait appel à un nombre d'éléments assez élevé. C'est notamment le cas pour la butée, dont la position est réglable, pour laquelle il faut prévoir un moyen de réglage. Il faut en général au moins une vis, une rondelle et un écrou, en plus de la butée proprement dite, pour obtenir le moyen de réglage. A cela s'ajoutent un temps d'assemblage assez long, un prix de fabrication assez élevé, et un poids également assez élevé. A ce propos l'arceau est en partie responsable, car il doit être suffisamment solide pour résister aux appuis verticaux exercés par la butée.Another disadvantage is the complexity of the structure. The seat, with its base and arch, is a three-dimensional piece whose shapes make it delicate to manufacture. Then the structure according to this first family uses a fairly high number of elements. This is particularly the case for the stop, whose position is adjustable, for which it must provide a means of adjustment. In general, at least one screw, a washer and a nut are required, in addition to the stopper itself, to obtain the adjustment means. In addition there is a long assembly time, a fairly high manufacturing price, and a weight also quite high. In this respect the arch is partly responsible because it must be strong enough to withstand the vertical supports exerted by the stop.

US 2009/0146397 A1 décrit le préambule de la revendication 1. US 2009/0146397 A1 describes the preamble of claim 1.

On le voit, même si les dispositifs connus permettent une conduite satisfaisante de la planche à laquelle ils sont associés, il est encore possible de les améliorer.As can be seen, even if the known devices allow a satisfactory driving of the board with which they are associated, it is still possible to improve them.

Il en découle que l'invention, qui sera décrite plus loin, a pour objectif général d'améliorer un dispositif d'accueil d'un pied sur un engin de sport.It follows that the invention, which will be described later, has the general purpose of improving a device for receiving a foot on a sports machine.

L'invention cherche notamment à améliorer le maintien du talon, c'est-à-dire à augmenter le confort et/ou la précision de tenue du talon. L'invention cherche également à simplifier la structure d'un dispositif. L'invention veut aussi réduire le nombre de pièces nécessaires à la fabrication. Par corollaire l'invention cherche à raccourcir le temps nécessaire à l'assemblage du dispositif, et à réduire son coût. L'invention veut encore diminuer le poids d'un dispositif d'accueil. Enfin un but de l'invention est de rendre le dispositif facile à manipuler, notamment en ce qui concerne le rabattement ou le déploiement de l'élément d'appui arrière par rapport à l'assise.The invention seeks in particular to improve the maintenance of the heel, that is to say to increase comfort and / or heel holding accuracy. The invention also seeks to simplify the structure of a device. The invention also wants to reduce the number of parts needed for manufacturing. By corollary the invention seeks to shorten the time required for assembly of the device, and reduce its cost. The invention further reduces the weight of a home device. Finally, an object of the invention is to make the device easy to handle, in particular as regards the folding or deployment of the rear support element relative to the seat.

Pour ce faire, l'invention propose un dispositif d'accueil d'un pied ou d'une chaussure sur un engin de glisse, le dispositif d'accueil comprenant une assise qui s'étend selon une direction longitudinale depuis une extrémité arrière jusqu'à une extrémité avant, ainsi qu'un élément d'appui arrière, l'élément d'appui arrière étant articulé relativement à l'assise, au niveau de l'extrémité arrière, de façon à pouvoir être rabattu vers l'assise ou déployé, le dispositif d'accueil comprenant une butée qui limite le déploiement de l'élément d'appui arrière par rapport à l'assise.To do this, the invention proposes a device for receiving a foot or a shoe on a gliding machine, the reception device comprising a seat which extends in a longitudinal direction from a rear end to a at a front end, and a rear support member, the rear support member being articulated relative to the seat, at the rear end, so as to be folded towards the seat or deployed , the receiving device comprising a stop which limits the deployment of the rear support element relative to the seat.

La butée, assujettie à l'assise, présente une structure autoporteuse. Le déploiement de l'élément d'appui arrière est limité par action de la butée selon la direction longitudinale.The stop, subject to the seat, has a self-supporting structure. The deployment of the rear support element is limited by action of the abutment in the longitudinal direction.

Le dispositif d'accueil selon l'invention est caractérisé par le fait que la butée est souple transversalement de manière à épouser la forme de l'élément d'appui arrière, lorsque celui-ci est déployé vers l'arrièreThe reception device according to the invention is characterized in that the stop is flexible transversely so as to match the shape of the rear support element, when it is deployed backwards.

Cet agencement permet l'adéquation entre la chaussure et l'élément d'appui arrière. En d'autres termes le contact entre la chaussure et l'élément d'appui arrière est plus régulier, voire uniforme. Par conséquent la répartition des pressions de contact entre ces deux composants est régulière. Il s'ensuit avantageusement que la tenue du talon est plus confortable et/ou plus précise.This arrangement allows the match between the shoe and the rear support element. In other words the contact between the shoe and the rear support element is more even or even. Therefore the distribution of the contact pressures between these two components is regular. It follows advantageously that the holding of the heel is more comfortable and / or more precise.

D'autre part l'agencement proposé simplifie la structure du dispositif d'accueil. Il en découle avantageusement que le nombre de pièces nécessaires à sa fabrication est réduit, que la durée d'assemblage est plus courte, et que le coût de fabrication est plus bas que pour les dispositifs connus. On observe aussi que le poids du dispositif selon l'invention est réduit, notamment parce qu'il est dépourvu d'arceau.On the other hand the proposed arrangement simplifies the structure of the host device. It follows advantageously that the number of parts needed for its manufacture is reduced, the assembly time is shorter, and the manufacturing cost is lower than for known devices. It is also observed that the weight of the device according to the invention is reduced, in particular because it lacks an arch.

On observe encore que la zone de rabattement de l'élément d'appui arrière reste dégagée, grâce à la nature autoporteuse de la butée. Il en découle avantageusement que les manipulations de rangement, par rabattement de l'élément d'appui vers l'assise, sont plus faciles.It is also observed that the folding zone of the rear support element remains unobstructed, thanks to the self-supporting nature of the abutment. It follows that the storage manipulations, by folding the support element towards the seat, are easier.

On peut résumer la situation en disant que l'invention est une amélioration d'un dispositif d'accueil.One can summarize the situation by saying that the invention is an improvement of a reception device.

Bien que les formes décrites ci-après se rapportent plutôt au domaine du snowboard, il doit être compris qu'elles s'appliquent aussi à d'autres domaines comme évoqué avant.Although the forms described below relate more to the field of snowboarding, it should be understood that they also apply to other areas as mentioned before.

La première forme d'exécution est présentée à l'aide des figures 1 à 7.The first form of execution is presented using the Figures 1 to 7 .

Comme on le voit sur la figure 1 en perspective, un dispositif d'accueil 1 permet l'accueil temporaire sur une planche 2 d'une chaussure non représentée.As we see on the figure 1 in perspective, a reception device 1 allows temporary reception on a board 2 of a shoe not shown.

De manière connue le dispositif d'accueil 1 comprend une assise 3 qui s'étend en longueur selon une direction longitudinale L entre une extrémité arrière 4 et une extrémité avant 5, et en largeur d'un premier bord 6 à un deuxième bord 7.In known manner the reception device 1 comprises a seat 3 which extends in length in a longitudinal direction L between a rear end 4 and a front end 5, and in width from a first edge 6 to a second edge 7.

L'assise 3 présente une face supérieure 8 prévue pour être en regard de la semelle de la chaussure, et une face inférieure 9 prévue pour être au-dessus de la planche 2.The seat 3 has an upper face 8 provided to be facing the sole of the shoe, and a lower face 9 provided to be above the board 2.

L'assise 3 comprend de préférence une embase 10, associée à un coussin arrière 11 et à un coussin avant 12. L'embase 10 est une pièce rigide qui délimite au moins en partie la face inférieure 9. Les coussins quant à eux délimitent au moins en partie la face supérieure 8. Selon la première forme d'exécution décrite, les coussins 11, 12 sont disposés respectivement à l'arrière et à l'avant de l'assise 3. Cela permet un contact amorti avec le talon ou la pointe de la semelle de la chaussure.The seat 3 preferably comprises a base 10, associated with a rear cushion 11 and a front cushion 12. The base 10 is a rigid piece which delimits at least partly the lower face 9. The cushions themselves delimit at less in part the upper face 8. According to the first embodiment described, the cushions 11, 12 are arranged respectively at the rear and at the front of the seat 3. This allows cushioned contact with the heel or the seat. tip of the sole of the shoe.

Bien entendu il peut être prévu d'autres structures pour l'assise 3, comme par exemple une embase associée à un coussin unique, lequel s'étend de l'extrémité arrière 4 à l'extrémité avant 5 de l'assise 3. Cette dernière est retenue à la planche 2 par un moyen réalisé sous la forme d'un disque 13, lui-même retenu à la planche 2 par des vis 14.Of course, other structures for the seat 3 may be provided, such as for example a base associated with a single cushion, which extends from the rear end 4 to the front end 5 of the seat 3. the last is retained in the board 2 by a means made in the form of a disc 13, itself retained in the board 2 by screws 14.

Bien entendu, d'autres moyens de retenue de l'assise 3 pourraient être prévus.Of course, other means of retaining the seat 3 could be provided.

L'assise 3 est bordée latéralement par une première partie représentée sous la forme d'un premier flasque 21, ainsi que par une deuxième partie représentée sous la forme d'un deuxième flasque 22. En l'occurrence le premier flasque 21 est latéral et le deuxième 22 est médial, mais cela aurait pu être le contraire. Les flasques 21, 22 sont reliés l'un à l'autre par l'embase 10. Ainsi les flasques 21, 22 et l'embase 10 délimitent une zone d'accueil 23 de la chaussure. Lorsque cette dernière est en place sur le dispositif 1, les flasques 21, 22 longent la semelle latéralement. Bien entendu il pourrait être prévu autre chose que les flasques 21, 22 pour former les parties latérale et médiale. Par exemple des butées pourraient convenir.The seat 3 is bordered laterally by a first portion shown in the form of a first flange 21, as well as by a second portion shown in the form of a second flange 22. In this case the first flange 21 is lateral and the second 22 is medial, but it could have been the opposite. The flanges 21, 22 are connected to each other by the base 10. Thus the flanges 21, 22 and the base 10 define a reception zone 23 of the shoe. When the latter is in place on the device 1, the flanges 21, 22 along the sole laterally. Of course it could be provided other than the flanges 21, 22 to form the lateral and medial parts. For example, stops might be suitable.

De préférence, l'embase 10 et les flasques 21, 22 forment une pièce monobloc réalisée par exemple en matière synthétique. Cependant il pourrait être prévu que les flasques 21, 22 soient des pièces solidarisées à l'embase par tout moyen, tel qu'un collage, une soudure, un vissage, un emboîtement, ou autre.Preferably, the base 10 and the flanges 21, 22 form a single piece made for example of synthetic material. However, it could be provided that the flanges 21, 22 are parts secured to the base by any means such as gluing, welding, screwing, interlocking, or other.

Il est également prévu deux liens pour maintenir de façon amovible la chaussure sur l'assise 3, entre les flasques 21, 22, dans la zone d'accueil 23.There are also two links for detachably holding the boot on the seat 3, between the flanges 21, 22, in the reception zone 23.

Un premier lien 24 se situe vers l'avant, au niveau de l'articulation métatarsophalangienne quand le pied est maintenu. Un deuxième lien 25 se situe vers l'arrière, au niveau du cou-de-pied quand le pied est maintenu.A first link 24 is located forward, at the metatarsophalangeal joint when the foot is maintained. A second link 25 is located aft, at the instep when the foot is held.

Chacun des liens 24, 25 s'étend transversalement entre les flasques 21, 22.Each of the links 24, 25 extends transversely between the flanges 21, 22.

Bien entendu il pourrait être prévu un nombre de liens différent.Of course it could be expected a number of different links.

Le dispositif 1 comprend aussi un élément d'appui arrière 29, pour que l'utilisateur puisse prendre des appuis arrière avec le bas de jambe. L'élément d'appui arrière 29 comprend un corps 30 qui s'étend longitudinalement entre des première 31 et deuxième 32 extrémités d'attache et une extrémité libre 33, transversalement entre un premier bord ou bord latéral 34 et un deuxième bord ou bord médial 35, et en épaisseur entre une face d'appui 36 et une face libre 37.The device 1 also comprises a rear support element 29, so that the user can take back supports with the lower leg. The rear support element 29 comprises a body 30 which extends longitudinally between first 31 and second 32 attachment ends and a free end 33, transversely between a first edge or lateral edge 34 and a second edge or medial edge 35, and in thickness between a bearing face 36 and a free face 37.

Bien entendu la face d'appui 36 est prévue pour recevoir l'arrière du bas de jambe de l'utilisateur, l'élément d'appui arrière 29 et l'assise 3 étant associés en conséquence, comme il sera décrit plus en détail après.Of course, the bearing face 36 is provided to receive the rear of the lower leg of the user, the rear support member 29 and the seat 3 being associated accordingly, as will be described in more detail after .

Comme on le comprend à l'aide des figures 1 à 3, l'élément d'appui arrière 29 est articulé relativement à l'assise 3, au niveau de l'extrémité arrière 4, de façon à pouvoir être rabattu vers l'assise ou déployé. Pour cela l'élément d'appui arrière est relié aux flasques 21, 22 au moyen d'une première articulation 41, située au niveau de la première extrémité d'attache 31, et au moyen d'une deuxième articulation 42, située au niveau de la deuxième extrémité d'attache 32. Ainsi la première extrémité d'attache 31 est reliée au premier flasque 21, et la deuxième extrémité d'attache 32 est reliée au deuxième flasque 22. Chaque articulation 41, 42 est respectivement orientée sensiblement selon un premier axe transversal 43 et un deuxième axe transversal 44 du dispositif 1. Chaque articulation 41, 42 autorise donc un mouvement de rotation de l'élément d'appui arrière 29 par rapport à l'assise 3. Un avantage qui en découle est de faciliter le rangement.As we understand it with the help of Figures 1 to 3 , the rear support member 29 is articulated relative to the seat 3, at the rear end 4, so as to be folded towards the seat or deployed. For this the rear support element is connected to the flanges 21, 22 by means of a first articulation 41, located at the first attachment end 31, and by means of a second articulation 42, located at the of the second attachment end 32. Thus the first attachment end 31 is connected to the first flange 21, and the second attachment end 32 is connected to the second flange 22. Each hinge 41, 42 is respectively oriented substantially in a first transverse axis 43 and a second transverse axis 44 of the device 1. Each articulation 41, 42 therefore allows a rotational movement of the rear support member 29 relative to the seat 3. A benefit that arises therefrom is to facilitate tidying up.

Le dispositif d'accueil 1 comprend encore une butée 49 qui limite le déploiement de l'élément d'appui arrière 29 par rapport à l'assise 3.The reception device 1 further comprises a stop 49 which limits the deployment of the rear support element 29 relative to the seat 3.

Selon l'invention la butée 49 est assujettie à l'assise 3, la butée 49 présente une structure autoporteuse, et la butée 49 limite le déploiement de l'élément d'appui arrière 29 par action selon la direction longitudinale L de l'assise 3. Cet agencement permet un contact plus régulier, voire uniforme, entre la chaussure et l'élément d'appui arrière. Aussi, l'agencement confère au dispositif d'accueil 1 une structure simple. Il en découle avantageusement que le nombre de pièces nécessaires à la fabrication est réduit, que la durée d'assemblage est courte, et que le coût de fabrication est relativement bas.According to the invention the stop 49 is secured to the seat 3, the stop 49 has a self-supporting structure, and the stop 49 limits the deployment of the rear support element 29 by action in the longitudinal direction L of the seat 3. This arrangement allows a more regular contact, even uniform, between the boot and the rear support element. Also, the arrangement gives the host device 1 a simple structure. It follows advantageously that the number of parts needed for manufacturing is reduced, the assembly time is short, and the manufacturing cost is relatively low.

D'autre part la nature autoporteuse de la butée 49 garantit que cette dernière reste en dehors de la zone de rabattement de l'élément d'appui arrière 29, dans le sens où la butée 49 n'est pas en vis-à-vis de l'embase 10. Un avantage qui en découle est une facilité de rangement, après rabattement de l'élément d'appui 29 vers l'assise 3.On the other hand, the self-supporting nature of the abutment 49 ensures that the latter remains outside the folding area of the rear support element 29, in the sense that the stop 49 is not opposite. of the base 10. An advantage that arises is ease of storage, after folding of the support element 29 to the seat 3.

De manière non limitative, selon la première forme de réalisation, la butée 49 est constituée par un arceau 50. Celui-ci comprend un support latéral 51, solidarisé au premier bord 6, un support médial 52, solidarisé au deuxième bord 7, ainsi qu'un pont 53 qui joint l'un à l'autre les supports latéral 51 et médial 52. On observe que l'arceau contourne l'élément d'appui arrière 29 du côté de la face libre 37.In a nonlimiting manner, according to the first embodiment, the stop 49 is constituted by a hoop 50. The latter comprises a lateral support 51, secured to the first edge 6, a medial support 52, secured to the second edge 7, as well as a bridge 53 which joins the lateral supports 51 and medial 52 to one another. It is observed that the arch circumvents the rear support element 29 on the side of the free face 37.

De manière plus précise, à titre d'exemple, le support latéral 51 comprend un tirant 61 et un pied 62. Le tirant 61 s'étend en longueur depuis une extrémité avant 63, solidarisée au premier flasque 21, jusqu'à une extrémité arrière 64, laquelle fait la jonction avec le pont 53. Le pied 62 relie le premier flasque 21 au tirant 61, au niveau de l'extrémité arrière 64 de ce dernier. Ainsi le tirant 61 est incliné par rapport au flasque 21 ou à l'assise 3, de façon que son extrémité arrière 64 soit éloignée de l'extrémité arrière 4 de l'assise 3. Bien entendu le tirant 61, et par corollaire le support 51, est orienté selon la direction longitudinale L de l'assise 3.More specifically, for example, the lateral support 51 comprises a tie rod 61 and a foot 62. The tie rod 61 extends in length from a front end 63, secured to the first flange 21, to a rear end 64, which joins the bridge 53. The foot 62 connects the first flange 21 to the tie rod 61, at the rear end 64 of the latter. Thus the tie rod 61 is inclined relative to the flange 21 or the seat 3, so that its rear end 64 is remote from the rear end 4 of the seat 3. Of course the tie 61, and by corollary support 51, is oriented in the longitudinal direction L of the seat 3.

Dans le même esprit, le support médial 52 comprend un tirant 71 et un pied 72. Le tirant 71 s'étend en longueur depuis une extrémité avant 73, solidarisée au deuxième flasque 22, jusqu'à une extrémité arrière 74, laquelle fait la jonction avec le pont 53. Le pied 72 relie le deuxième flasque 22 au tirant 71, au niveau de l'extrémité arrière 74 de ce dernier. Ainsi le tirant 71 est incliné par rapport au flasque 22 ou à l'assise 3, de façon que son extrémité arrière 74 soit éloignée de l'extrémité arrière 4 de l'assise 3. Bien entendu le tirant 71, et par corollaire le support 52, est orienté selon la direction longitudinale L de l'assise 3.In the same spirit, the medial support 52 includes a tie rod 71 and a foot 72. The tie rod 71 extends in length from a front end 73, secured to the second flange 22, to a rear end 74, which is the junction with the bridge 53. The foot 72 connects the second flange 22 to the tie rod 71, at the rear end 74 of the latter. Thus the tie rod 71 is inclined relative to the flange 22 or the seat 3, so that its rear end 74 is remote from the rear end 4 of the seat 3. Of course the tie 71, and by corollary support 52, is oriented in the longitudinal direction L of the seat 3.

On a vu que le pont 53 relie l'un à l'autre les supports latéral 51 et médial 52. Selon la première forme de réalisation décrite, le pont 53 relie l'une à l'autre les extrémités arrière 64, 74 des tirants 61, 71 des supports 51, 52. En conséquence le pont 53 est surélevé au-dessus de l'assise 3, dans la région de son extrémité arrière 4. On comprendra mieux par la suite que c'est cette disposition qui permet à l'arceau 50, et donc à la butée 49, de limiter le déploiement de l'élément d'appui arrière 29 par action selon la direction longitudinale L.It has been seen that the bridge 53 connects the lateral supports 51 and medial 52 to one another. According to the first embodiment described, the bridge 53 connects the rear ends 64, 74 of the tie rods to each other. 61, 71 supports 51, 52. Accordingly the bridge 53 is raised above the seat 3, in the region of its rear end 4. It will be better understood later that it is this provision that allows the hoop 50, and therefore at the stop 49, to limit the deployment of the rear support element 29 by action in the longitudinal direction L.

En conséquence, l'arceau 50 comprend une bande 75 formée par les tirants 61, 71 et le pont 53. En d'autres termes, la bande 75 relie un premier point d'ancrage 63 de l'arceau 50 sur l'assise 3 à un deuxième point d'ancrage 73 de l'arceau 50 sur l'assise 3. La largeur de la bande 75 est dans un plan sensiblement vertical alors que son axe longitudinal s'étend dans un plan P incliné d'un angle α par rapport à la face supérieure 8 de l'assise 3. L'angle α est compris entre 20° et 50°, préférentiellement autour de 30°. La bande 75 contourne l'élément d'appui arrière 29 du côté d'une face libre 37. La bande 75 forme la butée 49. Elle est souple transversalement de manière à épouser la forme de l'élément d'appui arrière 29, lorsque celui-ci est déployé vers l'arrière. Le déploiement de l'élément d'appui arrière 29 est donc limité par l'action de la bande 75 formant la butée 49 selon la direction longitudinale L.Consequently, the arch 50 comprises a band 75 formed by the tie rods 61, 71 and the bridge 53. In other words, the band 75 connects a first anchor point 63 of the bow 50 to the seat 3 at a second anchoring point 73 of the arch 50 on the seat 3. The width of the strip 75 is in a substantially vertical plane while its longitudinal axis extends in a plane P inclined at an angle α by the angle α is between 20 ° and 50 °, preferably around 30 °. The band 75 bypasses the rear support element 29 on the side of a free face 37. The band 75 forms the stop 49. It is flexible transversely so as to match the shape of the rear support element 29, when it is deployed backwards. The deployment of the rear support element 29 is limited by the action of the strip 75 forming the abutment 49 in the longitudinal direction L.

Cette construction permet un dimensionnement de la butée 49 optimisé et allégé par rapport aux arceaux classiques de l'art antérieur. En effet, pour limiter la rotation de l'élément d'appui arrière 29, la bande 75 est sollicitée dans le plan P ou selon une direction sensiblement proche de ce plan P. De ce fait, la bande 75 travaille en traction. L'effort exercé par l'élément d'appui arrière 29 est alors réparti longitudinalement entre les deux branches de la bande 75, à savoir les deux tirants 61, 71 et est repris au niveau des points d'ancrage 63 et 73. En étant sollicité principalement en traction, il est possible de concevoir la bande 75 de manière à privilégier la résistance en traction selon sa direction longitudinale correspondant à une sollicitation sensiblement dans le plan P. De même, cette construction permet d'octroyer de la souplesse de la bande 75 lorsqu'elle est sollicitée transversalement, c'est-à-dire par un effort sensiblement perpendiculaire à la largeur de la bande 75, puisque la butée 49 est peu sollicité transversalement lorsqu'elle doit bloquer la rotation de l'élément d'appui arrière 29. D'autre part, avec cette conception, la butée 49 est peu sollicitée verticalement ou selon une direction sensiblement perpendiculaire au plan P. En conséquence, il n'est pas nécessaire de dimensionner la butée 49 pour qu'elle soit très rigide et résistante lorsqu'elle est sollicitée selon une direction non coplanaire au plan P.This construction allows a dimensioning of the abutment 49 optimized and lightened compared to conventional arches of the prior art. Indeed, to limit the rotation of the rear support element 29, the band 75 is biased in the plane P or in a direction substantially close to this plane P. As a result, the band 75 works in tension. The force exerted by the rear support element 29 is then distributed longitudinally between the two branches of the strip 75, namely the two tie rods 61, 71 and is taken up at the anchor points 63 and 73. stressed mainly in tension, it is possible to design the band 75 so as to favor the tensile strength in its longitudinal direction corresponding to a substantially solicitation in the plane P. Similarly, this construction allows to grant the flexibility of the band 75 when it is biased transversely, that is to say by a force substantially perpendicular to the width of the band 75, since the stop 49 is not stressed transversely when it must block the rotation of the rear support element 29. On the other hand, with this design, the stop 49 is not stressed vertically or in a direction substantially perpendicular to the plane P. Consequently, it is not necessary to size the stop 49 to it is very rigid and resistant when it is requested in a direction not coplanar to the plane P.

En d'autres termes, la bande 75 fonctionne à la manière de haubans.In other words, the band 75 functions in the manner of stays.

On notera que dans l'art antérieur, les arceaux autoportés contribuant à limiter la rotation de l'élément d'appui arrière comprennent une structure renforcée et relativement rigide afin de résister à des sollicitations selon une direction sensiblement verticalement. Ce dimensionnement ajoute de la masse à la fixation et donc pénalise le confort de l'utilisateur. La majorité des fixations de l'état de la technique comprennent une pièce fixée sur l'élément d'appui arrière qui vient en contact avec le dessus de l'arceau. L'effort transmis entre l'élément d'appui arrière et l'arceau se passe au niveau de ce contact et est donc sensiblement vertical. L'arceau doit donc être suffisamment solide pour reprendre les efforts, d'où la rigidité verticale. De même, l'arceau doit résister à une sollicitation transversale pour assurer une bonne tenue de la pièce. L'arceau risque de s'affaisser lorsqu'il est contraint s'il n'est pas rigide transversalement. Les arceaux de l'art antérieur ne sont ainsi pas sollicités de la même façon que l'arceau faisant l'objet de cette invention. Ils travaillent généralement en compression plutôt qu'en traction.It will be noted that in the prior art, self-supporting arches contributing to limiting the rotation of the rear support element comprise a reinforced and relatively rigid structure in order to withstand stresses in a substantially vertical direction. This dimensioning adds weight to the binding and therefore penalizes the comfort of the user. Most of the fasteners of the state of the art comprise a part fixed on the rear support element which comes into contact with the top of the arch. The force transmitted between the rear support member and the hoop occurs at this contact and is therefore substantially vertical. The arch must be strong enough to take the effort, hence the vertical stiffness. Similarly, the hoop must withstand transverse stress to ensure good performance of the room. The arch may collapse when forced if it is not rigid transversely. The hoops of the prior art are thus not solicited in the same way as the hoop forming the object of this invention. They usually work in compression rather than traction.

Compte tenu du fait que la bande 75 est principalement sollicitée en traction, il est avantageux que celle-ci soit dimensionnée pour améliorer sa résistance à la traction longitudinale. Pour cela, la bande 75 peut comprendre un fil, une sangle, une matière incluant des fibres orientées longitudinalement. La bande 75 peut également comprendre plusieurs matériaux. Par exemple, un canal en matériau plastique de type PU ou polyester dans lequel passe une sangle et/ou un fil en matériau de type PA ou PE UHMW. Il peut y avoir une discontinuité de matériaux le long de la bande 75 si celle-ci assure, dans toute sa longueur, une bonne résistance en traction longitudinale.Given the fact that the strip 75 is mainly stressed in tension, it is advantageous that it is sized to improve its longitudinal tensile strength. For this, the band 75 may comprise a wire, a strap, a material including fibers oriented longitudinally. The band 75 may also include several materials. For example, a channel of plastic material of the PU or polyester type in which passes a strap and / or a wire of PA or PE UHMW material. There may be a discontinuity of materials along the band 75 if it provides, throughout its length, a good longitudinal tensile strength.

Ce qui importe dans cette construction, c'est la présence de la bande 75 enveloppante, entourant l'élément d'appui arrière 29 et ancrée sur l'assise 3, et, préférentiellement à l'avant de l'assise 3 afin travailler le plus possible en traction. Pour s'assurer que la butée 49 est autoportée, l'arceau 50 intègre des pieds 62, 72. On peut envisager de cloisonner, partiellement ou non, l'espace entre les pieds 62, 72 et la bande 75.What matters in this construction is the presence of the enveloping strip 75, surrounding the rear support element 29 and anchored on the seat 3, and preferably at the front of the seat 3 to work the seat. more possible in traction. To ensure that the stop 49 is self-supporting, the arch 50 incorporates feet 62, 72. It is conceivable to partition, partially or not, the space between the feet 62, 72 and the band 75.

Selon la première forme de réalisation, l'arceau 50 comprend un lien, réalisé sous la forme d'une sangle 80, qui s'étend le long du support latéral 51, et le long du support médial 52. La portion de sangle qui relie les supports 51, 52 forme le pont 53. En d'autres termes le lien 80 forme le pont 53. Plus précisément la sangle 80 longe le tirant 61 du support latéral 51, ainsi que le tirant 71 du support médial 52, la sangle 80 reliant l'une à l'autre les extrémités arrière 64, 74 des tirants 61, 71.According to the first embodiment, the arch 50 comprises a link, made in the form of a strap 80, which extends along the lateral support 51, and along the medial support 52. The portion of strap that connects the supports 51, 52 form the bridge 53. In other words the link 80 forms the bridge 53. More specifically, the strap 80 runs along the tie rod 61 of the lateral support 51, that the tie rod 71 of the medial support 52, the strap 80 connecting to each other the rear ends 64, 74 tie rods 61, 71.

Bien entendu la sangle 80 est souple transversalement et inextensible. De ce fait la sangle 80 peut être pliée mais ne s'allonge pas, au moins dans des conditions normales d'utilisation. C'est pourquoi l'arceau 50, et donc la butée 49, épouse totalement la forme de l'élément d'appui arrière 29, lorsque celui-ci est déployé vers l'arrière comme c'est le cas sur les figures 2 et 3. On observe que les tirants 61, 62 et la sangle 80, et donc par corollaire le pont 53, viennent au contact de la face libre 37 de l'élément d'appui arrière 29, de manière à exercer un appui à plat sur celle-ci 37. Etant donné que les tirants 61, 71 sont orientés longitudinalement vers l'avant 5 de l'assise 3, ils 61, 71 sont sollicités en traction lorsqu'une chaussure pousse l'élément d'appui arrière 29 dans un sens de déploiement, vers l'arrière 4. Bien entendu le pont 53 est alors également sollicité en traction. Il s'ensuit que la butée 49, par son arceau 50, agit sur l'élément d'appui arrière 29 à la manière de haubans. C'est pourquoi la butée 49 limite le déploiement de l'élément d'appui arrière 29 par action selon la direction longitudinale L de l'assise 3. Le mode d'action de la butée 49 permet de lui conférer la structure simple décrite avant. Il est en effet beaucoup plus facile, d'un point de vue mécanique, de gérer des efforts de traction.Of course the strap 80 is transversely flexible and inextensible. As a result, the strap 80 can be folded but does not lengthen, at least under normal conditions of use. This is why the hoop 50, and therefore the stop 49, fully matches the shape of the rear support element 29, when it is deployed rearward as is the case on the figures 2 and 3 . It is observed that the tie rods 61, 62 and the strap 80, and thus corollary the bridge 53, come into contact with the free face 37 of the rear support element 29, so as to exert a flat support on it. 37. Since the tie rods 61, 71 are oriented longitudinally towards the front 5 of the seat 3, they 61, 71 are urged in tension when a shoe pushes the rear support element 29 in a direction of Deployment, rearward 4. Of course the bridge 53 is then also stressed in traction. It follows that the stop 49, by its hoop 50, acts on the rear support element 29 in the manner of guys. That is why the stop 49 limits the deployment of the rear support element 29 by action in the longitudinal direction L of the seat 3. The mode of action of the stop 49 allows to confer the simple structure described before . It is indeed much easier, from a mechanical point of view, to manage traction forces.

Selon la première forme de réalisation décrite, les supports latéral 51 et médial 52 présentent sensiblement les mêmes dimensions, et sont en regard l'un de l'autre transversalement. Par corollaire les tirants 61, 71 et les pieds 62, 72 sont en regard l'un de l'autre transversalement et le pont 53 est parallèle à l'assise 3. Cela équilibre les efforts de traction exercés par la butée 49, c'est-à-dire par l'arceau 50. En effet, ces efforts se répartissent de façon équilibrée entre le premier bord 6 et le deuxième bord 7 : les efforts de traction dans le tirant 61 du support latéral 51 sont égaux ou proches des efforts de traction dans le tirant 71 du support médial 52. Cela amène une stabilité d'appui de la chaussure sur l'élément d'appui arrière 29.According to the first embodiment described, the lateral supports 51 and medial 52 have substantially the same dimensions, and are facing each other transversely. By corollary the tie rods 61, 71 and the feet 62, 72 are facing each other transversely and the bridge 53 is parallel to the seat 3. This balances the traction forces exerted by the stop 49, c ' that is to say by the hoop 50. Indeed, these efforts are distributed in a balanced manner between the first edge 6 and the second edge 7: the tensile forces in the tie rod 61 of the lateral support 51 are equal or close to the forces traction in the tie rod 71 of the medial support 52. This brings a stability of support of the boot on the rear support element 29.

On remarque que l'extrémité avant 63 du tirant 61, et donc du support latéral 51, est plus proche de l'extrémité avant 5 que de l'extrémité arrière 4. Dans le même esprit l'extrémité avant 73 du tirant 71, et donc du support médial 52, est plus proche de l'extrémité avant 5 que de l'extrémité arrière 4. Ainsi, les axes longitudinaux des tirants 61 et 71 forment le plan P. Lorsque la face libre 37 de l'élément d'appui arrière 29 appuie sur l'arceau 50, cette face libre 37 est perpendiculaire, ou sensiblement perpendiculaire au plan P, comme on le comprend notamment à l'aide de la figure 2. Cette configuration optimise le travail en traction, selon la direction longitudinale L et vers l'avant 5, de l'arceau 50, et donc de la butée 49.Note that the front end 63 of the tie rod 61, and therefore of the lateral support 51, is closer to the front end 5 than the rear end 4. In the same spirit the front end 73 of the tie rod 71, and therefore the medial support 52 is closer to the front end 5 than the rear end 4. Thus, the longitudinal axes of the tie rods 61 and 71 form the plane P. When the free face 37 of the support element rear 29 presses the hoop 50, this free face 37 is perpendicular, or substantially perpendicular to the plane P, as is understood in particular by means of the figure 2 . This configuration optimizes the work in traction, in the longitudinal direction L and forward 5, of the hoop 50, and therefore of the stop 49.

Comme on le comprend non seulement à l'aide des figures 1 à 3, mais aussi à l'aide des figures 4 et 5, la position de l'élément d'appui arrière 29 par rapport à l'assise 3 peut être ajustée. Cela signifie qu'il est possible d'avancer ou de reculer, au choix, chacune des extrémités d'attache 31, 32. On peut dire que la position de chaque articulation 41, 42 est réglable par rapport à l'assise 3, ou aux flasques 21, 22. Un déplacement est obtenu, à titre d'exemple, par démontage puis remontage d'une ou des deux articulations 41, 42 de l'élément d'appui arrière 29 relativement à l'assise 3.As we understand it not only with the help of Figures 1 to 3 , but also with the help of Figures 4 and 5 , the position of the rear support member 29 relative to the seat 3 can be adjusted. This means that it is possible to advance or retreat, as desired, each of the attachment ends 31, 32. It can be said that the position of each articulation 41, 42 is adjustable relative to the seat 3, or flanges 21, 22. A displacement is obtained, as a for example, by disassembly and reassembly of one or both joints 41, 42 of the rear support member 29 relative to the seat 3.

Comme le montrent les figures 4 et 5 dans le cas du flasque médial 22, l'articulation 42 comprend par exemple une vis 85 et un écrou 86. Le flasque médial 22 présente ici deux orifices 87, 88 pour accueillir la vis 85, sachant qu'il est alternativement possible d'en prévoir plus, ou de réaliser une fente. Dans tous les cas, l'axe de la vis, l'axe d'un orifice 87, 88 et l'axe 44 de la deuxième articulation se confondent. Bien entendu, il en est de même pour l'articulation 41 au niveau du flasque latéral 21.As shown by Figures 4 and 5 in the case of the medial flange 22, the articulation 42 comprises for example a screw 85 and a nut 86. The medial flange 22 here has two orifices 87, 88 to accommodate the screw 85, knowing that it is alternatively possible to plan more, or make a slot. In all cases, the axis of the screw, the axis of an orifice 87, 88 and the axis 44 of the second joint merge. Of course, it is the same for the articulation 41 at the side flange 21.

De manière concrète, sur la figure 4, la deuxième extrémité d'attache 32 est disposée dans une position reculée le long du flasque médial 22. Elle 32 est donc au plus près de l'extrémité arrière 4. Par contre, sur la figure 5, l'extrémité d'attache 32 est disposée dans une position plus avancée. Elle se trouve donc moins proche de l'extrémité arrière 4. Bien entendu, la position de l'articulation 42 change.In concrete terms, on the figure 4 , the second attachment end 32 is disposed in a retracted position along the medial flange 22. It 32 is therefore closer to the rear end 4. By cons, on the figure 5 , the attachment end 32 is disposed in a more advanced position. It is therefore less close to the rear end 4. Of course, the position of the hinge 42 changes.

Il est possible de sélectionner des positions en vis-à-vis l'une de l'autre ou, alternativement, décalées l'une par rapport à l'autre, pour les articulations 41, 42. En conséquence la position de l'élément d'appui arrière 29 peut être avancée, reculée, ou réglée en rotation selon un axe virtuel perpendiculaire à l'assise 3. Ce mécanisme permet donc de régler l'inclinaison de l'élément d'appui arrière 29 lorsqu'il entre en contact avec la butée 49 et de régler l'orientation angulaire de l'élément d'appui arrière 29 autour d'un axe sensiblement vertical.It is possible to select positions facing each other or, alternatively, offset relative to each other, for the articulations 41, 42. Consequently the position of the element rear support 29 can be advanced, retreated, or set in rotation along a virtual axis perpendicular to the seat 3. This mechanism thus allows the inclination of the rear support element 29 to be adjusted when it comes into contact with the stop 49 and adjust the angular orientation of the rear support member 29 about a substantially vertical axis.

Dans le mode de réalisation décrit, seulement deux orifices 87, 88 par flasque 22 illustrent le mécanisme de réglage. Bien entendu, on peut envisager plus d'orifices ou d'autres moyens incorporant des crans afin de permettre un plus grand nombre de configurations de réglage de l'inclinaison et/ou de l'orientation angulaire de l'élément d'appui arrière 29.In the embodiment described, only two orifices 87, 88 per flange 22 illustrate the adjustment mechanism. Of course, it is possible to envisage more orifices or other means incorporating notches in order to allow a greater number of configurations for adjusting the inclination and / or the angular orientation of the rear support element. .

On remarque en complément que l'épaisseur e de chaque support 52, 53, mesurée par exemple au niveau du pied 62, est inférieure à l'épaisseur E du flasque 22 auquel il est assujetti. Par exemple l'épaisseur e d'un support est comprise entre 0,5 et 5mm, sachant que des valeurs de 1 à 3mm ont donné des résultats satisfaisants. Une épaisseur réduite des supports 51, 52, et donc des tirants 61, 71 et des pieds 62, 72, est suffisante pour leur conférer leur résistance mécanique en traction, tout en autorisant une souplesse transversale. Cela améliore l'aptitude de la butée 49 à épouser la forme de l'élément d'appui arrière 29. L'épaisseur E du flasque 22, quant à elle, est comprise entre 5 et 15mm, sachant que des valeurs de 5 à 8mm ont donné des résultats satisfaisants. Une épaisseur plus importante des flasques 21, 22 donne à l'assise3 une rigidité, qui permet par exemple un maintien transversal précis de la semelle de la chaussure.It is noted in addition that the thickness e of each support 52, 53, measured for example at the foot 62, is less than the thickness E of the flange 22 to which it is subject. For example, the thickness e of a support is between 0.5 and 5 mm, knowing that values of 1 to 3 mm have given satisfactory results. A reduced thickness of the supports 51, 52, and therefore tie rods 61, 71 and feet 62, 72, is sufficient to impart their tensile strength, while allowing transverse flexibility. This improves the ability of the stop 49 to match the shape of the rear support element 29. The thickness E of the flange 22, meanwhile, is between 5 and 15mm, knowing that values of 5 to 8mm have given satisfactory results. A greater thickness of the flanges 21, 22 gives the seat3 a rigidity, which allows for example a precise transverse support of the sole of the shoe.

Bien entendu l'assise 3, dont les flasques 21, 22, ainsi que les supports 51, 52, sont réalisés à partir de tous les matériaux convenables, tels que des matières plastiques.Of course the seat 3, including the flanges 21, 22, and the supports 51, 52, are made from all suitable materials, such as plastics.

Selon la première forme de réalisation de l'invention, chaque support 51, 52 est une pièce rapportée sur l'assise 3, c'est-à-dire en pratique solidarisée à un flasque 21, 22. Par corollaire la butée 49, ou l'arceau 50, est une pièce rapportée sur l'assise 3. La solidarisation est par exemple réalisée par emboîtement, lequel est consolidé par l'articulation 41, 42 concernée. En effet, en plus de permettre un basculement de l'élément d'appui arrière 29, chaque articulation, avec sa vis 85 et son écrou 86, maintient un support 51, 52 au contact d'un flasque 21, 22. Il est donc possible de réaliser un support, ou les deux, avec un matériau différent de celui de l'assise 3, c'est-à-dire différent de celui constitutif des flasques 21, 22. Bien entendu le matériau constitutif des supports 51, 52 est choisi plus flexible que le matériau constitutif de l'assise 3. Cela permet de conférer aux différents éléments du dispositif 1 les propriétés mécaniques appropriées.According to the first embodiment of the invention, each support 51, 52 is an insert on the seat 3, that is to say in practice secured to a flange 21, 22. By corollary the stop 49, or the hoop 50 is an insert on the seat 3. The fastening is by example made by interlocking, which is consolidated by the articulation 41, 42 concerned. Indeed, in addition to allowing a tilting of the rear support element 29, each joint, with its screw 85 and its nut 86, maintains a support 51, 52 in contact with a flange 21, 22. It is therefore possible to make a support, or both, with a material different from that of the seat 3, that is to say different from that constituting the flanges 21, 22. Of course the material constituting the supports 51, 52 is chosen to be more flexible than the material constituting the seat 3. This makes it possible to confer on the various elements of the device 1 the appropriate mechanical properties.

Comme on le comprend notamment à l'aide de la figure 6, chaque tirant 61, 71 présente un guide 91 prévu pour coopérer avec la sangle 80. Le guide 91 est ici réalisé sous la forme d'une rainure dans laquelle est placée la sangle 80. Cette dernière est donc naturellement maintenue le long des tirants 61, 71. Cet agencement préserve la qualité autoporteuse de la butée 49, ou de l'arceau 50, tout en bénéficiant de la souplesse de la sangle 80 notamment dans son rôle au niveau du pont 53.As is understood in particular by using the figure 6 , each tie 61, 71 has a guide 91 provided to cooperate with the strap 80. The guide 91 is here in the form of a groove in which is placed the strap 80. The latter is naturally maintained along the ties 61 , 71. This arrangement preserves the self-supporting quality of the abutment 49, or the hoop 50, while enjoying the flexibility of the strap 80 especially in its role at the bridge 53.

Sans que cela soit obligatoire il est possible, comme détaillé à la figure 7, d'ajuster la tension de la sangle 80. Par corollaire, grâce à la souplesse transversale des supports 51, 52, la longueur de l'arceau 50 est réglable. Cela permet d'ajuster la géométrie de la butée 49 pour qu'elle corresponde le plus précisément possible à la forme de la chaussure. Le maintien de cette dernière n'en est que meilleur.Without this being obligatory it is possible, as detailed in the figure 7 to adjust the tension of the strap 80. By corollary, thanks to the transverse flexibility of the supports 51, 52, the length of the hoop 50 is adjustable. This makes it possible to adjust the geometry of the stop 49 so that it corresponds as closely as possible to the shape of the shoe. The maintenance of the latter is only better.

En pratique, le dispositif d'accueil 1 comprend un moyen de réglage de la longueur de la sangle 80. Par exemple, une extrémité 92 de la sangle 80 présente une boucle 93 assujettie à une vis 94. Bien entendu la vis 94 est logée dans un flasque 22. Une molette 95, qui peut être actionnée à la main, coopère avec la vis 94 pour maintenir ou modifier la longueur utile de la sangle 80. Au final la longueur de l'arceau 50 est ajustée à l'aide de la molette 95.In practice, the reception device 1 comprises a means for adjusting the length of the strap 80. For example, an end 92 of the strap 80 has a loop 93 secured to a screw 94. Of course the screw 94 is housed in 22. A wheel 95, which can be actuated by hand, cooperates with the screw 94 to maintain or modify the useful length of the strap 80. In the end the length of the hoop 50 is adjusted using the wheel 95.

La deuxième forme de réalisation est présentée ci-après à l'aide de la figure 8. Pour des raisons de commodité, les parties semblables à la première forme sont désignées par les mêmes références.The second embodiment is presented below using the figure 8 . For the sake of convenience, similar parts in the first form are designated by the same references.

On retrouve donc de manière générale un dispositif d'accueil 1 avec notamment une assise 3, des premier 21 et deuxième 22 flasques, un élément d'appui arrière 29, ainsi qu'une butée 49.Thus generally there is a reception device 1 including a seat 3, first 21 and second 22 flanges, a rear support member 29 and a stop 49.

Ce qui caractérise le dispositif 1 selon la deuxième forme, c'est la structure de la butée 49. Si celle-ci est encore un arceau 100 qui comprend un support latéral 101, un support médial 102, et un pont 103, les supports 101, 102 et le pont 103 forment ici une pièce monobloc. Autrement dit l'arceau 100 est une pièce monobloc. Etant donné que, comme précédemment, un support latéral 101 ou médial 102 comprend respectivement un tirant 111, 121, un pied 112, 122, une extrémité avant 113, 123 et une extrémité arrière 114, 124, les tirants 111, 121, les pieds 112, 122 et le pont 103 forment une pièce monobloc. Celle-ci est par exemple réalisée avec une matière plastique dont l'épaisseur est comprise entre 0,5 et 5mm, sachant que des valeurs de 1 à 3mm ont donné des résultats satisfaisants.What characterizes the device 1 according to the second form is the structure of the stop 49. If it is still a hoop 100 which comprises a lateral support 101, a medial support 102, and a bridge 103, the supports 101 , 102 and the bridge 103 form here a single piece. In other words the hoop 100 is a single piece. Since, as previously, a lateral support 101 or medial 102 respectively comprises a tie rod 111, 121, a foot 112, 122, a front end 113, 123 and a rear end 114, 124, the tie rods 111, 121, the feet 112, 122 and the bridge 103 form a single piece. This is for example made with a plastic whose thickness is between 0.5 and 5mm, knowing that values of 1 to 3mm have given satisfactory results.

Le fonctionnement de la butée 49 est analogue au premier mode de réalisation.The operation of the stop 49 is similar to the first embodiment.

L'arceau 100 comprend également une bande 175 enveloppante, entourant l'élément d'appui arrière 29 et ancrée à l'avant 113, 123 de l'assise 3 afin travailler le plus possible en traction. La bande 175 comprend une partie du support 101, une partie du support 102 et le pont 103.The hoop 100 also comprises an enveloping strip 175, surrounding the rear support element 29 and anchored to the front 113, 123 of the seat 3 to work as much as possible in tension. The band 175 comprises a part of the support 101, a part of the support 102 and the bridge 103.

L'arceau 100 présente une structure autoporteuse. Il est souple transversalement de manière à épouser la forme de l'élément d'appui arrière 29, lorsque celui-ci est déployé vers l'arrière. Le déploiement de l'élément d'appui arrière 29 est donc limité par l'action de la bande 175 formant la butée 49 selon la direction longitudinale L.The hoop 100 has a self-supporting structure. It is transversely flexible so as to match the shape of the rear support element 29, when it is deployed rearwardly. The deployment of the rear support element 29 is limited by the action of the strip 175 forming the abutment 49 in the longitudinal direction L.

De manière non limitative l'arceau 100, ou butée 49, forme lui-même avec l'assise 3 une pièce monobloc. Cependant, il peut alternativement être prévu que l'arceau soit une pièce différente de l'assise 3, et rapportée sur cette dernière par tout moyen connu de l'homme du métier.In a nonlimiting manner the hoop 100, or stop 49, itself forms with the seat 3 a single piece. However, it may alternatively be provided that the arch is a different part of the seat 3, and reported on the latter by any means known to those skilled in the art.

Alternativement, la bande 175 peut comprendre une rainure destinée à recevoir un fil ou une sangle de maintien analogue à la sangle 80 du premier mode de réalisation. Ce renfort permet d'améliorer la tenue à la traction de la bande 175 et donc d'améliorer la tenue de la butée 49.Alternatively, the band 175 may comprise a groove for receiving a wire or a strap similar to the strap 80 of the first embodiment. This reinforcement makes it possible to improve the tensile strength of the strip 175 and thus to improve the holding of the stopper 49.

D'une manière générale, l'invention est réalisée à partir de matériaux et selon des techniques de mise en oeuvre connus de l'homme du métier.In general, the invention is made from materials and according to implementation techniques known to those skilled in the art.

Bien entendu l'invention n'est pas limitée à la forme d'exécution décrite, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Naturally, the invention is not limited to the embodiment described, and includes all the technical equivalents that fall within the scope of the following claims.

Par exemple la butée 49, ou l'arceau 50, 100, peut comprendre un seul matériau ou au contraire plusieurs parties en matériaux différents. Dans ce second cas les parties sont assujetties les unes aux autres, soit en étant fixes, soit en étant mobiles les unes par rapport aux autres. Notamment, la sangle 80 peut être immobilisée, ou au contraire glisser dans son guide 91.For example, the stop 49, or the hoop 50, 100 may comprise a single material or on the contrary several parts of different materials. In this second case the parts are subject to each other, either by being fixed or by being movable relative to each other. In particular, the strap 80 can be immobilized, or on the contrary slide in its guide 91.

La butée 49 et plus particulièrement la bande 75, 175 pourrait par exemple comprendre une série de secteurs articulés les uns aux autres, à la manière d'une chaine ou d'un bracelet de montre.The stop 49 and more particularly the band 75, 175 could for example comprise a series of sectors articulated to each other, in the manner of a chain or a watch band.

Préférentiellement, les premier et deuxième points d'ancrage 63, 113 ; 73, 123 des bandes 75, 175 sont, tous deux, proches de l'extrémité avant de l'assise 3, dans la première moitié de la longueur de l'assise 3, avantageusement dans le premier tiers.Preferably, the first and second anchor points 63, 113; 73, 123 strips 75, 175 are, both, close to the front end of the seat 3, in the first half of the length of the seat 3, preferably in the first third.

Avantageusement, la largeur de la bande 75, 175 est inferieure à deux centimètres afin d'avoir une structure allégée.Advantageously, the width of the band 75, 175 is less than two centimeters in order to have a lightened structure.

La bande 75, 175 peut être de forme filaire. Dans ce cas, elle fait partie d'une structure autoportée.The band 75, 175 may be of wire form. In this case, it is part of a self-supporting structure.
