Description

DISPOSITIF ESCAMOTABLE DE SUPPORT DE JAMBES À CACHE DE SÉCURITÉ, POUR UN SIÈGE  RETRACTABLE LEG SUPPORT DEVICE WITH SECURITY COVER, FOR A SEAT
L'invention concerne les sièges qui sont équipés d'un dispositif escamotable destiné à permettre le support des jambes (ou mollets) d'une personne. The invention relates to seats that are equipped with a retractable device for supporting the legs (or calves) of a person.
Certains sièges, qui sont par exemple destinés à être implantés dans des véhicules, éventuellement de type automobile, sont équipés d'un dispositif escamotable de support de jambes (parfois appelé "repose mollets"). De tels dispositifs comprennent tous un support de jambes qui est solidarisé soit à une structure télescopique fixée sous l'assise du siège et destinée à permettre son déplacement entre une position escamotée sous l'assise et une position désescamotée devant cette assise (comme décrit dans le document brevet US 2005/173963), soit à une structure de maintien qui est solidarisée à des moyens de coulissement destinés à permettre son déplacement entre les positions escamotée et désescamotée.  Some seats, which are for example intended to be installed in vehicles, possibly of the automotive type, are equipped with a retractable leg support device (sometimes called "calf rest"). Such devices all include a leg support which is secured to either a telescopic structure fixed under the seat of the seat and intended to allow its movement between a retracted position under the seat and a position désescamotée in front of this seat (as described in the document US 2005/173963) or to a holding structure which is secured to sliding means intended to allow its movement between the retracted and désescamotée positions.
L'invention concerne plus particulièrement les dispositifs escamotables du dernier type, et encore plus précisément ceux dont la structure de maintien délimite une zone centrale évidée et dont les moyens de coulissement sont placés sous cette zone centrale. Lorsque le support est en position désescamotée, la zone centrale évidée est placée devant l'assise et donc les moyens de coulissement sont apparents ce qui est inesthétique. Par ailleurs, lorsque le support est en position désescamotée, il existe un risque que la personne qui est assise sur le siège place l'un au moins de ses pieds dans la zone centrale évidée, ce qui peut provoquer un désagrément, voire une blessure.  The invention relates more particularly to the retractable devices of the latter type, and even more specifically those whose holding structure defines a central recessed area and whose sliding means are placed under this central zone. When the support is in the désescamotée position, the central recessed area is placed in front of the seat and therefore the sliding means are apparent which is unsightly. Moreover, when the support is in the désescamotée position, there is a risk that the person who sits in the seat places at least one of his feet in the central recessed area, which can cause inconvenience or injury.
L'invention a donc pour but de remédier au moins partiellement aux inconvénients précités lorsque le dispositif escamotable est du dernier type.  The invention therefore aims to remedy at least partially the aforementioned drawbacks when the retractable device is of the latter type.
Elle propose à cet effet d'équiper le dispositif escamotable d'un cache (de sécurité) solidarisé à sa structure de maintien de manière à boucher une partie au moins de la zone centrale et à masquer au moins partiellement ses moyens de coulissement. It proposes for this purpose to equip the retractable device with a cover (security) secured to its holding structure so as to plug at least part of the central area and to hide at least partially its sliding means.
De préférence, la structure de maintien est située entre l'assise et le support de jambes, en position désescamotée.  Preferably, the holding structure is located between the seat and the leg support, in the désescamotée position.
La structure de maintien est préférentiellement distincte à la fois d'une 5 part du support de jambes et d'autre part de l'assise.  The support structure is preferentially distinct both on the one hand from the leg support and on the other hand from the seat.
Le cache ne présente avantageusement, en position désescamotée, aucun contact avec le support de jambes. Avantageusement, le cache ne présente pas non plus de contact avec l'assise, en position désescamotée.  The cover advantageously has, in désescamotée position, no contact with the leg support. Advantageously, the cover does not have contact with the seat either, in the désescamotée position.
Le dispositif escamotable selon l'invention peut comporter d'autres ) caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :  The retractable device according to the invention may comprise other features that can be taken separately or in combination, and in particular:
- son cache peut être réalisé dans un matériau choisi parmi (au moins) un matériau plastique, un matériau synthétique et une toile;  its cover can be made of a material chosen from (at least) a plastic material, a synthetic material and a fabric;
- sa structure de maintien peut comprendre une partie arrière qui est 5 destinée à être logée sous l'assise et qui est munie de premiers moyens de fixation agencés de manière à permettre la solidarisation d'une partie arrière du cache à la structure de maintien;  its holding structure may comprise a rear part which is intended to be housed under the seat and which is provided with first fastening means arranged so as to allow the attachment of a rear part of the cover to the holding structure;
la partie arrière du cache peut comprendre deux ouvertures, et les premiers moyens de fixation peuvent comprendre deux pattes de the rear part of the cover may comprise two openings, and the first fixing means may comprise two legs of

- il peut comprendre des seconds moyens de fixation agencés pour solidariser une partie avant du cache à une partie avant de la structure de maintien;  it may comprise second fastening means arranged to secure a front portion of the cover to a front portion of the holding structure;
5 les seconds moyens de fixation peuvent être agencés sous la forme d'une barre comprenant une partie centrale à laquelle est solidarisée la partie avant du cache, et deux parties d'extrémité agencées de manière à être solidarisées à la partie avant de la structure de maintien; dans une variante les seconds moyens de fixation peuvent être agencés ) sous la forme d'un cordon comprenant une partie centrale à laquelle est solidarisée la partie avant du cache, et deux parties d'extrémité agencées de manière à être solidarisées à la partie avant de la structure de maintien; The second fastening means may be arranged in the form of a bar comprising a central part to which the front part of the cover is secured, and two end parts arranged so as to be secured to the front part of the support structure; maintenance; alternatively the second fastening means may be arranged) in the form of a bead comprising a central portion to which the front portion of the cover is secured, and two end portions arranged to be secured to the front portion of the the structure maintenance;
son support de jambes peut comprendre, au niveau de deux extrémités opposées, deux pattes de fixation qui sont agencées pour être solidarisées à la partie avant de la structure de maintien;  its leg support may comprise, at two opposite ends, two fixing lugs which are arranged to be secured to the front portion of the holding structure;
5 - ses moyens de coulissement peuvent comprendre au moins un rail qui est agencé de manière à permettre la solidarisation de la structure de maintien, et au moins une glissière qui est propre à être solidarisée au siège et qui est agencée de manière à permettre le coulissement du rail par rapport au siège. Its sliding means may comprise at least one rail which is arranged so as to allow the holding structure to be secured, and at least one slide which is adapted to be secured to the seat and which is arranged so as to allow sliding rail relative to the seat.

5 Les dessins annexés pourront non seulement servir à compléter l'invention, mais aussi contribuer à sa définition, le cas échéant.  The accompanying drawings may not only serve to complete the invention, but may also contribute to its definition, as appropriate.
L'invention a pour but d'offrir un dispositif escamotable de support de jambes (D) destiné à équiper un siège (SI).  The invention aims to provide a retractable leg support device (D) for equipping a seat (SI).
Dans ce qui suit, on considère, à titre d'exemple non limitatif, que le ) siège (SI) est destiné à être installé sur le plancher d'un véhicule, éventuellement de type automobile. Mais, l'invention n'est pas limitée à cette application. Elle concerne en effet tout type de siège pouvant être installé sur une surface pouvant supporter des personnes (au moins en position assise).In the following, we consider, by way of non-limiting example, that the seat (SI) is intended to be installed on the floor of a vehicle, possibly of the automotive type. But, the invention is not limited to this application. It concerns indeed any type of seat that can be installed on a surface that can support people (at least sitting).
Par ailleurs, on considère dans ce qui suit, à titre d'exemple non limitatif, que le siège (SI) est destiné à recevoir une seule personne. Mais, il pourrait s'agir d'une banquette destinée à recevoir au moins deux personnes.Furthermore, it is considered in the following, by way of non-limiting example, that the seat (SI) is intended to receive a single person. But, it could be a bench designed to accommodate at least two people.
5 On a schématiquement représenté sur la figure 1 un exemple de structure de siège SI comportant une partie inférieure, constituant une partie d'une assise AS et destinée à être solidarisée (éventuellement en translation) à un plancher (ici de véhicule), et une partie supérieure, constituant une partie d'un dossier DS et éventuellement montée à rotation sur la partie inférieure.FIG. 1 schematically shows an example of a seat structure S1 comprising a lower part, constituting part of a seat cushion AS and intended to be secured (possibly in translation) to a floor (here of a vehicle), and a upper part constituting part of a DS folder and possibly rotatably mounted on the lower part.
) Comme illustré, ce siège SI est équipé sous son assise AS d'un dispositif (escamotable de support de jambes) D selon l'invention (ici sans son cache CH afin de permettre la visualisation de moyens de coulissement MC). As illustrated, this seat SI is equipped under its seat AS of a device (retractable leg support) D according to the invention (here without its cache CH to allow viewing of sliding means MC).
Un tel dispositif D comprend, comme illustré sur les figures 2 à 4, au moins un support de jambes SJ, une structure de maintien SM, des moyens Such a device D comprises, as illustrated in FIGS. 2 to 4, at least one leg support SJ, a support structure SM, means

Le support de jambes SJ est destiné, une fois désescamoté de dessous l'assise AS, à supporter les jambes d'au moins une personne (et plus précisément au moins la partie des jambes comportant les mollets). Il s'agit d'un élément en forme générale de plateau, et présentant éventuellement une The leg support SJ is intended, once désescamotés from under the seat AS, to support the legs of at least one person (and more precisely at least the part of the legs with calves). This is an element in the general shape of a tray, and possibly having a

Ce support de jambes SJ est solidarisé à une partie avant PV1 de la structure de maintien SM, par exemple (et comme illustré non limitativement) au moyen de deux pattes de fixation PF1 qui sont solidarisées à deux de ses This leg support SJ is secured to a front portion PV1 of the holding structure SM, for example (and as illustrated without limitation) by means of two brackets PF1 which are secured to two of its
5 extrémités (latérales) opposées. Par exemple, les deux pattes de fixation PF1 sont solidarisées par vissage ou boulonnage ou encore clippage étroit à la partie avant PV1 de la structure de maintien SM. Ces deux pattes de fixation PF1 sont par exemple réalisées en matière plastique ou synthétique rigide. 5 opposite ends (side). For example, the two fixing lugs PF1 are secured by screwing or bolting or close clipping to the front portion PV1 of the holding structure SM. These two fixing lugs PF1 are for example made of rigid plastic or synthetic material.
La structure de maintien SM délimite une zone centrale évidée ZC. The holding structure SM defines a hollow central zone ZC.
) Comme illustré non limitativement sur la figure 3, elle est par exemple en forme générale de U. Pour ce faire, elle comprend par exemple une tubulure pliée (ou conformée ou moulée) en forme de U. Cette tubulure peut par exemple être réalisée en métal ou en matière plastique ou synthétique rigide. Par ailleurs, cette tubulure comprend une partie arrière PR1 qui constitue la partie transversale de liaison du U, et deux parties longitudinales qui constituent les deux parties latérales du U et dont les extrémités libres définissent la partie avant PV1 de la structure de maintien SM. On 5 comprendra que les deux pattes de fixation PF1 sont solidarisées respectivement au niveau des deux extrémités libres de la tubulure. On notera que la partie arrière PR1 de la structure de maintien SM est préférentiellement destinée à être logée sous l'assise AS, comme illustré non limitativement sur la figure 1 . As shown in non-limiting manner in FIG. 3, it is, for example, generally U-shaped. To do this, it comprises, for example, a U-shaped folded (or shaped or molded) tubing. metal or rigid plastic or synthetic material. Furthermore, this tubing comprises a rear portion PR1 which constitutes the transverse connecting portion of the U, and two longitudinal portions which constitute the two lateral parts of the U and whose free ends define the front portion PV1 of the holding structure SM. It will be understood that the two fixing lugs PF1 are secured respectively at the two free ends of the tubing. Note that the rear portion PR1 of the holding structure SM is preferably intended to be housed under the seat AS, as shown in non-limiting manner in FIG.
) Les moyens de coulissement MC sont placés sous la zone centrale ) The sliding means MC are placed under the central zone
ZC. Ils sont agencés de manière à permettre le déplacement de la structure de maintien SM (et donc du support de jambes SJ) entre des positions escamotée et désescamotée. ZC. They are arranged so as to allow the displacement of the holding structure SM (and thus of the leg support SJ) between retracted and undecomposed positions.
La position escamotée est celle dans laquelle le support de jambes The retracted position is that in which the leg support
5 SJ, la structure de maintien SM et les moyens de coulissement MC sont rangés sous l'assise AS. La position désescamotée est celle dans laquelle le support de jambes SJ et une partie au moins de la structure de maintien SM et des moyens de coulissement MC sont placés devant l'assise AS afin de permettre le support des jambes d'au moins une personne assise sur cette5 SJ, the holding structure SM and the sliding means MC are stored under the seat AS. The désescamotée position is that in which the leg support SJ and at least part of the holding structure SM and sliding means MC are placed in front of the seat AS to allow the support of the legs of at least one seated person on this

Chaque glissière G est propre à être solidarisée au siège SI et est agencée de manière à permettre le coulissement, d'avant en arrière, du rail R par rapport au siège SI, afin de faire passer le dispositif de sa position escamotée à sa position désescamotée, et inversement. Each slide G is adapted to be secured to the seat S1 and is arranged to allow sliding, from front to rear, of the rail R relative to the seat SI, to move the device from its retracted position to its désescamotée position, and vice versa.
Il est important de noter que dans l'exemple non limitatif illustré les moyens de coulissement MC ne comportent qu'un rail R et une glissière G, 5 installés dans une position sensiblement centrale (ou médiane). Mais, ils pourraient comporter deux rails R sensiblement parallèles et deux glissières G sensiblement parallèles.  It is important to note that in the nonlimiting example illustrated, the sliding means MC comprise only one rail R and one slide G, installed in a substantially central (or median) position. But, they could comprise two substantially parallel rails R and two substantially parallel rails G.
Le cache (de sécurité) CH est solidarisé à la structure de maintien SM de manière à boucher une partie au moins de la zone centrale ZC et à ) masquer au moins partiellement les moyens de coulissement MC qui sont placés sous cette dernière (ZC).  The (safety) cover CH is secured to the holding structure SM so as to plug at least part of the central zone ZC and at least partially mask the sliding means MC which are placed under the latter (ZC).
On comprendra que lorsque le support de jambes SJ est dans sa position désescamotée (illustrée sur la figure 2), sa zone centrale évidée ZE It will be understood that when the leg support SJ is in its unshranked position (illustrated in FIG. 2), its central recessed area ZE
(qui est placée devant l'assise AS) ne constitue plus un danger pour les pieds 5 d'une personne du fait qu'elle est désormais bouchée (ou obstruée) par le cache CH. En outre, le rail R des moyens de coulissement MC se retrouve masqué par le cache CH, si bien qu'ils ne constituent pas un élément inesthétique. (which is placed in front of the seat AS) is no longer a danger to the feet 5 of a person because it is now blocked (or obstructed) by the cache CH. In addition, the rail R sliding means MC is hidden by the cache CH, so they do not constitute an unsightly element.
Grâce au mode de réalisation proposé par l'invention, même si le ) support de jambes SJ se retrouve placé dans une position intermédiaire, comprise entre les positions escamotée et désescamotée, il n'existe quasiment aucun risque de se blesser étant donné que la zone centrale évidée ZC est en permanence bouchée (quasi totalement).  Thanks to the embodiment proposed by the invention, even if the leg support SJ is placed in an intermediate position, between the retracted and unshranked positions, there is virtually no risk of injury since the central recessed ZC is permanently clogged (almost completely).
Le cache CH peut être rigide ou semi-rigide ou encore souple, selon 5 les variantes de réalisation. Pour ce faire, il peut par exemple être réalisé dans un matériau plastique ou synthétique (rigide ou semi-rigide ou souple), par exemple par moulage, ou bien en toile (synthétique ou en fibres naturelles).  The cache CH can be rigid or semi-rigid or flexible, depending on the embodiments. To do this, it may for example be made of a plastic or synthetic material (rigid or semi-rigid or flexible), for example by molding, or canvas (synthetic or natural fibers).
Afin d'assurer la solidarisation de la partie arrière PR2 du cache CH à ) la structure de maintien SM, la partie arrière PR1 de cette dernière (SM) peut par exemple (et comme illustré non limitativement sur les figures 2 et 3) être munie de premiers moyens de fixation MF1 .  In order to ensure that the rear portion PR2 of the cover CH) is secured to the holding structure SM, the rear part PR1 of the latter (SM) may for example (and as illustrated in non-limiting manner in FIGS. 2 and 3) be provided with first fixing means MF1.
Comme illustré non limitativement sur les figures 2 et 3, les premiers moyens de fixation MF1 peuvent par exemple comprendre deux pattes de fixation qui sont solidarisées à la partie transversale de la tubulure, qui définit la partie arrière PR1 de la structure de maintien SM, et qui sont chacune munies d'un ergot (ou d'une saillie) EG, de préférence orienté vers le haut (ouAs illustrated without limitation in FIGS. 2 and 3, the first fixing means MF1 may for example comprise two fixing lugs which are secured to the transverse portion of the tubing, which defines the rear portion PR1 of the holding structure SM, and which are each provided with a lug (or a protrusion) EG, preferably facing upwards (or

Dans ce cas, la partie arrière PR2 du cache CH peut comprendre (comme illustré non limitativement sur les figures 2 et 4) deux ouvertures OV destinées à permettre le passage des deux ergots EG. 5 slightly to the back). In this case, the rear part PR2 of the cover CH may comprise (as illustrated not only in FIGS. 2 and 4) two openings OV intended to allow the passage of the two lugs EG.

Par exemple, et comme illustré non limitativement sur les figures 2 et 4, ces seconds moyens de fixation MF2 peuvent être agencés sous la forme d'une barre (ou tubulure) comprenant, d'une part, une partie centrale à laquelle est solidarisée la partie avant PV2 du cache CH, et, d'autre part, deux For example, and as illustrated in non-limiting manner in FIGS. 2 and 4, these second fixing means MF2 may be arranged in the form of a bar (or tubing) comprising, on the one hand, a central part to which is secured the front part PV2 of the cache CH, and, on the other hand, two
) parties d'extrémité agencées (ici recourbées) de manière à être solidarisées à la partie avant PV1 de la structure de maintien SM, par exemple par introduction en force (ou emmanchement) dans les deux extrémités libres des parties longitudinales de la tubulure (ou inversement par insertion en force (ou emmanchement) des deux extrémités libres des parties longitudinales de la) end portions arranged (here curved) so as to be secured to the front portion PV1 of the holding structure SM, for example by force introduction (or fitting) into the two free ends of the longitudinal portions of the tubing (or conversely by insertion into force (or fitting) of the two free ends of the longitudinal parts of the
5 tubulure). 5 tubing).
On notera que la partie avant PV2 du cache CH peut être solidarisée à la partie centrale de la barre MF2 par tout moyen connu de l'homme de l'art, et notamment grâce à une partie d'extrémité repliée sur elle-même pour définir un logement de barre (par couture ou au moyen d'au moins un bouton ) pression ou d'une paire de bandes auto-agrippantes (à crochets ou boucles), éventuellement de type velcro®, ou de bandes complémentaires de fermetures à glissières), ou munie d'un profilé plastique cousu ou moulé destiné à s'ancrer sur la barre. Avec ce mode de réalisation, l'assemblage de la structure de maintien SM et du cache CH peut se faire comme indiqué ci-après. On peut commencer par solidariser la partie centrale de la barre MF2 à la partie avant PV2 du cache CH. Puis, on introduit les deux parties d'extrémité recourbées 5 de la barre MF2 dans les deux extrémités libres des parties longitudinales de la tubulure de la structure de maintien SM. Enfin, on rapproche la partie arrière PR2 du cache CH de la partie arrière PR1 de la tubulure de la structure de maintien SM afin de faire passer les ergots EG des premiers moyens de fixation MF1 dans les ouvertures OV du cache CH. It will be noted that the front portion PV2 of the cover CH may be secured to the central portion of the bar MF2 by any means known to those skilled in the art, and in particular by virtue of an end portion folded back on itself to define a bar seat (by sewing or by means of at least one button) pressure or a pair of self-gripping strips (hooks or loops), possibly velcro® type, or complementary strips of zippers) , or provided with a plastic sewn or molded profile intended to anchor itself on the bar. With this embodiment, the assembly of the holding structure SM and the cache CH can be done as indicated below. We can begin by joining the central part of the bar MF2 to the front portion PV2 cache CH. Then, the two curved end portions 5 of the bar MF2 are introduced into the two free ends of the longitudinal portions of the tubing of the holding structure SM. Finally, the rear portion PR2 of the cover CH is brought closer to the rear portion PR1 of the tubing of the holding structure SM in order to pass the lugs EG of the first attachment means MF1 in the openings OV of the cover CH.
î o D'autres modes de réalisation, non représentés, des seconds moyens de fixation MF2 peuvent être envisagés. Ainsi, ils peuvent être agencés sous la forme d'un cordon comprenant, d'une part, une partie centrale à laquelle est solidarisée la partie avant PV2 du cache CH, et, d'autre part, deux parties d'extrémité qui sont agencées de manière à être solidarisées à la partie avantOther embodiments, not shown, of the second fixing means MF2 may be envisaged. Thus, they can be arranged in the form of a bead comprising, on the one hand, a central part to which the front part PV2 of the cover CH is fastened, and, on the other hand, two end parts which are arranged so as to be secured to the front part
