Abstract

The vehicle has slider shoes fixed to a structural chassis frame (3) and a cab interior and rear storage space separating structure (33) with a carcass (35). The structure and backrests (11a) of seats are connected together to define an assembly sliding along the shoes and relative to a base (11b) of the related seats to reduce and increase the depth of the base in slid position towards front and back of the vehicle, respectively. An independent claim is also included for a process for rendering a vehicle modular.

Description

In a notable aspect is concerned here the management of the relative space

available, in-

  vehicle, in particular an automobile, between the passenger compartment and a rear storage space located behind this cabin.

  More generally it is a question of making modular a vehicle having a longitudinal axis and comprising a passenger compartment, a structural frame, seats located in the passenger compartment and comprising a backrest, and a rear storage space located behind the passenger compartment with respect to the front of the vehicle.

  Space management at the location of at least some of the seats of the vehicle is thus concerned.

  In some cases, there are indeed problems difficult to reconcile place: for example, either has a wider cabin (especially in length along the longitudinal axis' X of the vehicle) and a rear space smaller storage (especially shorter along this axis X), the opposite.

  An inventive aspect aims here in particular to reconcile such requirements and to promote an interesting management of space on a vehicle.

  It is a hybrid solution that is proposed by a sliding assembly of said seat backs and a planned separation structure between the passenger compartment and the rear storage space, these folders and the separation structure being linked together, so that defining a sliding assembly along rails fixed to the structural frame and with respect to the seat of said seats, thus reducing a dimension of this seat substantially along the longitudinal axis of the vehicle, in the sliding position towards the front of the vehicle of this assembly, and increasing this same dimension, in the retracted position of the assembly.

  To further combine strength, safety and comfort, it is recommended that: the separation structure comprises a reinforcement and security reinforcement rising above the upper limit of said seat backs concerned and extending generally transversely to the longitudinal axis (X) of the vehicle, - that the vehicle comprises a cockpit roof, - and that sealing means are interposed between this roof and the separation structure, to ensure a watertight slip between this separation structure and roof.

  The modularity can also be understood between the separation structure and a surrounding area of the frame and / or said roof, in particular to manage here the longitudinal position of vehicle elements situated, in height, between the body at substantially the level of top of the doors and the top of the separation structure.

  For this, it is advisable that this separation structure comprises a partition and / or a rear window extending substantially perpendicularly to the longitudinal axis of the vehicle, the partition and / or the pane thus sliding with said seat backs, along the slides.

  Another aspect of this modularity relates to the advantageously transformable character of the vehicle, between for example a coupe and a convertible, whether with a trunk lid or barrel cover (barrel cover).

  In this case, it is expected that the vehicle is equipped with a movable roof (hard top, roof articulated several parts, soft top ..) can occupy a first position in which it covers at least partly the cockpit and a second position in which the cabin is at least partially cleared, said roof then being located away from the top of the livable it covered in the first position.

  Advantageously, this mobile roof will be hingedly mounted on the structural frame of the vehicle between its first and second positions, substantially at the location of a rear position of said seat back, so that the roof can be stored or removed from space rear storage, that said assembly constituted by the backs of said seats and the separation structure is in the rear sliding position or in the sliding position further.

  Yet another aspect of this modularity relates to the recovery of the rear storage space, in particular to allow the use of the vehicle pick up.

  For this, it is recommended that the vehicle comprises a main covering cover of the rear storage space, this main cover bordering, at least locally, an auxiliary cover, and - it makes articulable auxiliary cover relative to the main cover, around a pivot axis transverse to the longitudinal axis of the vehicle, - makes articulable relative to the structural frame of said vehicle the main cover, by pivoting about a pivot axis transverse to the longitudinal axis of the vehicle, - the auxiliary cowl is made separable from the main cowl and thus from the vehicle as a whole, releasably connecting the auxiliary cowl and the main cowl forwardly and rearwardly of said auxiliary cowl, and obtain a pick-up version of said vehicle, said auxiliary cover is removed from it, releasing its front and rear linkage means with the main cover, opening a insi in the open at least part of said rear storage space.

  In summary, it will be possible in principle to modulate: the depth of the rear storage space with respect to the passenger compartment, and / or the use of the vehicle between different versions, in particular pick up, and / or obtain a covered or uncovered vehicle: hard top, soft top, rigid roof in several parts hinged together and / or relative to the structural frame of the vehicle.

  Other features and advantages will become apparent from the following detailed description given with reference to the accompanying drawings, in which: FIG. 1 is a diagrammatic view in longitudinal section (X axis) of a vehicle, FIG. in partial perspective of the vehicle of Figure 1 and Figure.3 is a variant - Figure 4 is a top view, partial, of Figure 1 - Figure 7 corresponds to the section VII-VII of Figure 4 and FIG. 6 in section VI-VI of FIG. 5, FIGS. 8 to 12 show the operating steps, FIG. 13 corresponds to section XIII-XIII of FIG. 7 and FIG. 14 to section XIV. -XIV of this same figure 13.

  1 shows a vehicle 1 comprising a structural frame 3 defining, in the upper part, a roof which, with a surrounding area of the structural frame 3 (which comprises the frame, the doors, longitudinal members, sleepers, ...), defines interior passenger compartment 7.

  This cockpit 7 accommodates at least four seats distributed for example in pairs in two rows of seats, respectively before 9 and rear 11.

  The passenger compartment 7 is covered by the roof 5, which is here a fixed roof integrated in the structure 3 and which extends longitudinally (along the longitudinal axis X of the vehicle) between the upper cross member 13 of the windshield and, at the rear, a rear window (or bezel) 15, that is to say substantially up to the mobile cowl 17 of the rear trunk 19.

  It will now be noted that the window 15, which is erected generally transversely to the longitudinal axis X, may be independent of the roof 5 (see below).

  This rear limit also defines, and substantially, the front of a mobile cowl assembly 17 adapted to cover or release access to a rear storage area 19 which may be considered, in particular, as a platform of pick-up (Figure 2) as a trunk (Figure 3).

  The cover assembly 17 includes a main cover 107 and an auxiliary cover 117, smaller in length and width.

  The two covers are movable, the auxiliary cover 117 relative to the main cover 107 and the latter relative to the structural frame 3, so as to open them, or close, one without the other and even be able to remove the cover auxiliary 117, in the pick-up configuration of FIG.

  For this, and as is best described in FIG. 3, where the circles schematize locking means and the rectangles of the pivots, we find, with a symmetry with respect to the X axis: - rear transverse pivots 119a, 119b each comprising first pivoting elements 120 and second pivoting complementary elements 121 respectively connected to the main cowl 107 and to the structural frame 3, in the transversal portion 3a of the lower body, just above the rear bumper, for the pivoting of the cowl 107 relative to at frame 3; front transverse pivots 123a, 123b each comprising first pivoting elements 124 and second complementary pivoting elements 126 respectively connected to the main cowl 107 and to the auxiliary cowl 117 for pivoting (including, if desired, to the withdrawal by disengagement) of the auxiliary cover 117 relative to the main cover; - Front side locks 127a, 127b for releasably locking the main cover relative to the structural frame, when the first is folded over, against the second. These latches each comprise first movable locking elements (such as a bolt) 128, movably mounted on for example the main cover and second fixed complementary locking elements 130 (such as a striker) then fixed to the structural frame 3; and a rear latch 131 for the releasable locking of the auxiliary cover 117 relative to the main cover 107, when the first is folded over, against the second. This lock, here central, comprises first movable locking elements 132, for example mobile on the auxiliary cover and second complementary locking elements 134 then attached to the main cover.

  We understand the terms front and rear with reference to the front ends (AVT) and rear (ARR) of the vehicle and note that the pivot axes of the aforementioned pivots here are parallel to the Y axis of the vehicle and therefore perpendicular to its longitudinal axis X. Thus, the main cover 107 opens (here only) by tilting towards the rear of the vehicle and the auxiliary cover to the front, of course this in the unlocked (released) state of the aforementioned locking elements.

  As for the means of detachable hinges defined by said pivot elements 124, 126 of the transverse pivots before 123a, 123b, they therefore allow pivoting until disengagement, that is to say until separation at this point between the auxiliary hood 117 and the main hood 107.

  Figures 5 and 6 show the articulation between the auxiliary cover and the main cover made in the form of such detachable hinges.

  In Fig. 5 a bent rod 200 is secured through a wafer 201 to an inner surface of the auxiliary hood 117, in the vicinity of the front edge 117a of the auxiliary hood. The curved rod has a radius of curvature R which is centered towards the front edge of the auxiliary hood. The main cover 107 which is seen in section in Figure 6 has a curved tube 203 of complementary shape to the curved rod 200 and the same radius as this rod. The curved tube 203 is fixed to the main cover by means of a wafer 205 fixed on an inner surface 107 'of the cover 107, the wafer being connected to the tube by two connecting elements 207, 209 having plate shapes. In operating position when opening and closing the auxiliary cover 117, the bent rod 200 slides guided in the complementary tube 203. To remove the auxiliary cover simply rotate it by an angle such that the stem out of the guide tube: the auxiliary cover is then disengaged from the main cover 107 and can be removed from the vehicle. In normal operation a stop system (not shown) limits the pivot angle so as not to disengage the cover involuntarily.

  The device shown is obviously not limiting of the embodiments: by way of example the curved rod 200 may be replaced by a curved flat profile. Similarly, the curved tube 203 can be replaced by rollers whose axes of rotation are parallel to the pivot axis of the auxiliary cover and which are arranged to guide the curved rod along its radius of curvature.

  Figures 1 and 2, it is also found that the main cover thus borders the auxiliary cover 117, here on three sides, since the cover 107 has a generally U-shaped with two side portions 107a, 107b generally parallel to the X axis (Hood closed) and a transverse portion 107c connecting the two side portions, rear, so close to the rear shield 125. The two covers 107, 117 open and are closed here by tilting about axes parallel to the Y axis, opposite to each other.

  At the location of these two lateral parts 107a, 107b of the main cover, situated on either side of the auxiliary cover, two bars 127, 129 are connected to this main cover and extend along these lateral parts, essentially following two directions parallel to each other.

  These two bars are advantageously pivotally mounted towards a rear end, around two coaxial axes, respectively 127d, 129d, substantially parallel to the pivot axis defined by the pivoting elements of the main cover relative to the structural frame 3 (called thirds pivoting members) thus belonging here to said rear transverse pivots 119a, 119b.

  Thus, these bars, or arches as they can be curved shape, curved downwards, are pivotable relative to the main cover, to pivot between a position inclined relative to the cover 107 and a position folded against it, along its lateral parts 107a, 107b.

  To maintain these two positions, each lateral bar and, opposite, the main cover for the folded position and the rear of the roof 5 for the inclined position, are equipped with complementary locking means, respectively 131a, 131b; 133a, 133b, to lock these side bars in the two aforementioned positions.

  As for the locking systems already presented, these additional releasable locking means may comprise on one side a movable bolt on for example each bar and latches then fixed to the main cover for the folded position and at the rear of the roof 5 for the inclined position.

  For this reason, in 56a, 56b (see also Fig. 7), the roof 5 extends substantially in its axial longitudinal continuity, by two lateral protuberances equipped with latches 131a, 133a.

  Favorably, in their inclined position, tilted upwards, the lateral bars will come substantially in the continuity of the profile of the roof, when it is arranged above the passenger compartment 7.

  Regarding the roof 5, it is expected that it will be a priori a movable roof between a first position in which it covers at least partly the passenger compartment 7 and a second position in which the cabin is at least partially clear, with the roof away from the top of the cockpit. Favorably, it will even be an articulated roof vis-à-vis the frame 3, even if a removable roof (by complete separation with the frame 3 and thus the vehicle) is possible, for example a hard top.

  Moreover, this roof 5 is here a rigid roof, although a flexible articulated soft top is possible. This is in particular a roof comprising at least two parts 55a, 55b, respectively a front portion 55a and a rear portion 55b located behind the front portion at least in said first position of the roof above the passenger compartment 7 these front and rear portions being hinged relative to one another about a first pivot 57 extending substantially perpendicular to the longitudinal axis X of the vehicle, the rear portion being further articulated relative to the structural frame 3 of the vehicle around a second pivot 59 extending substantially perpendicular to said longitudinal axis X of the vehicle, so that the passage of the roof from its first to its second position includes a folding of said front and rear portions of the roof one to the other.

  The rear portion 55b even comprises here a rear central portion 155b and two rear lateral portions 157b, 159b (see FIGS. 1 to 4) mounted around transverse pivoting axes, substantially parallel to the Y axis in this closed state of the roof, to articulate between them, between the positions deployed above the passenger compartment and folded at the location of the rear space 19 (mixed lines Figure 7).

  Whether it is a pick-up version, or transformable as from for example a convertible or a coupe, as in Figure 2, or a discoverable version as in Figures 3 and 7 , the rear storage space (or loading) 19 is located below the top of the rear window 15 and, here, the roof 5 then in its covered state of the passenger compartment 7.

  Note that the window 15 may, as here, be mechanically or functionally independent of the roof 5 and be directly connected or not to the frame 3 relative to which it can be slidably mounted parallel to the axis X, between a rear position shown in a line full fig. 7 and a more advanced position shown in phantom, increasing accordingly the axial dimension of the rear space 19. For this, the window or rear window 15 may be attached to a frame 35 which stands up above the limit of the folders 11a seats 11 located at the rear limit of the passenger compartment and down to the level of rails or rails 21, which extend substantially along X (possibly with a slight slope rising forward). The frame 35 slides along them, while being able to be locked at least in two positions limiting more or less the axial length of the passenger compartment. To this frame is fixed a partition 29 extended above by the upper pane 15 which together define a structure 33 for separation between the passenger compartment 7 and the rear storage space 19.

  The frame 35 may in particular consist of a roll bar extending across the width of the vehicle and which we see a possible embodiment in Figures 2 and 3 (form generally u-shaped).

  Figure 2, where the auxiliary cover 117 has been removed, by disengagement vis-àvis the main cover 107, the space 19 defines a rear platform in the open, open on top and back. The lateral bars 127, 129 are raised and locked to the lateral protuberances 56a, 56b of the roof. The main cover 107 is closed, locked to the frame 3.

  In Figure 3, the two covers 107, 117 are mounted on the vehicle 1, in the folded and locked position.

  In this case, the rear space 19 storage (or loading) is a trunk that close the main cover 107 and the auxiliary cover 117 and the relative dimensions of the rear trunk and the roof 5 are adapted so that the roof can be stored in the trunk in its second position, in the version envisaged here, and preferred, a convertible vehicle and specifically discoverable by folding the roof in the trunk 19.

  From a covered state 7 covered (for example in the case of a four-seater coupe as in Figure 1, to move to a four-seater pick-up state, as in Figure 2, simply unlock the auxiliary cover 117 relative to the main cover 107, that is to say to release from each other the locking means 131, 132, 134 and to do the same for the releasable means of pivoting before 123a, 123b; , as in FIG. 2, the rear platform 19 then appears fully accessible and it is possible for example to fix transverse bars, or directly an object such as a bicycle, to the lateral bars 127, 129 then locked to the rear of the roof 5, upright.

  From the same state of Figure 1, roof at least partially covering the passenger compartment 7, it is also possible to transform the vehicle into an open vehicle (convertible).

  If the roof 5 is a roof hinged to the frame -3 of the vehicle, the procedure is as follows, assuming, for example, where, as here, this roof comprises the roof parts already mentioned 55a, 155b, 157b and 159b (see figs .4 and 8 to 12).

  First of all, the releasable locking means identified 135, in particular in FIG. 10, are unlatched in particular and partly provided on the front roof portion 55a and partly on the upper windshield bolster 13.

  It is also ensured that the lateral bars 127, 129 are in the lower position as in FIG. 5; otherwise they are unlocked vis-à-vis the rear of the roof, as 56a in Figure 8, and then locked in the folded position on the side portions 107a, 107b of the main cover 107 by acting on the means of aforementioned locks such as 133a in Figure 4.

  One can then unlock the front locking means such as 127a in Figures 4 and 9, for releasing the main cover 107 relative to the structural frame 3.

  This cover can thus open, here by swinging backwards so its rear pivoting means such as 119a, Figure 10.

  If it is mounted on the main cover, the auxiliary cover 117 (then locked to it) rotates along with the main cover, as shown in the same figure.

  Figure 11, we see that we can then control (especially by any known automatic and motorized control) the roof 5 so as to store it inside the trunk 19.

  In the illustrated embodiment, the front portion 55a of the roof then articulates with respect to the central rear portion 155b, around the first pivot 57 and the same rear central portion pivots itself relative to the structural frame 3 around the second rear transverse pivot 57.

  At the same time, the rear lateral parts (157b, 159b) have themselves pivoted about their axes, so as to reduce the overall width and to be able to pass laterally in the width authorized by the opening of the covers.

  In the closed position of the roof, the rear side portions 157b, 159b are usually (and in known manner) folded inwards and the front and rear central portions 55a, 155b are folded one above the other, substantially horizontally.

  The hoods 107, 117 can then be closed by tilting forwards, as can be seen in FIG. 12, in which the auxiliary hood 117 is always closed and locked, while it has just been locked at the front, in the folded position, the main cover 107, by action on its locking means such as 127a.

  The passenger compartment 7 is then fully exposed, on the top and we see, in Figure 12, in rear limit thereof the separation structure 33, here with the transverse bar 35 carrying the rear window 15 which well forms a rear window independent of the movements of the roof 5.

  Advantageously, if the slides 21 already mentioned are provided, the opening and closing of the roof 5 as presented above for an articulated roof vis-à-vis the structural frame 3, can be carried out both in position of the separation structure 33 slid backwards along the slides 21 in the forwardly slidable position, while the backs 11a of the rear seats 11 involved impose these seats a reduced seat depth.

  In this respect, it will be noted again in FIG. 7 that the rear seats 11 (or the rear seat, if it is one) has a seat backrest 11a fixed at an inclination with respect to the seat 11b, but slidably mounted on the runners. such that 21 whose axis 21 is thus directed substantially parallel to the axis X, that is to say generally in the longitudinal direction of the vehicle, even if here the slide 21 shown, which is in this case rectilinear, present a slope with respect to the horizontal X (angle a), the rear of the slide being lower than the front.

  Although FIG. 13 refers to the variant embodiment of FIGS. 3 and 7, it nevertheless shows that the external lateral limit 110a of the sliding backrest 11a of the illustrated left-hand portion of the rear seats 11 is mounted on the corresponding left slide 21 by means of a wing 23 forming a lateral protrusion and cooperating with this slide 21.

  Of course, we imagine the symmetry to the right of the vertical axis Z, for a right slide 21 and a symmetrical environment.

  FIG. 14 shows the front 37a and rear 37b positions of the separation structure 33.

  Returning to FIG. 13, it can be seen that the slide 21 defines a rim of the structural frame 3 at the location of the rear wheel arch 25, the slide 21 being connected at the front to the top of the slope 27a of the bottom profile 27 rear body which is profiled to receive the lower part of the rear door concerned.

  The lia records of seats are therefore planned to a priori maintain their slight inclination backwards relative to the vertical, thus favoring a normally inclined seat of the passenger on this seat, the backrest lia is favorably in support at the rear upper part against a partition 29 which is surmounted, or which integrates in the upper part, the rear window 15 which here extends globally along the Y axis. It could of course be bent and / or not be vertical, but slightly inclined forward or backwards, as well as the partition 29, depending on the design and other contingencies.

  The assembly constituted by the partition 29 and the upper pane 15 defines said structure 33 for separation between the passenger compartment 7 and the rear storage space 19, this structure 33 being mechanically linked to the rear backrest 11 and thus sliding with it. The separation structure 33 could also be made differently. 10

  Here, this separation structure is attached to an armature 35 rising above the upper limit of the seat backs 11a and down to the level of the rails or rails 21, as seen in FIG. left part.

  The armature 35 may in particular consist of a roll bar which we see a possible embodiment in this Figure 3 (generally U-shaped inverted extending over the entire width of the vehicle).

  The lla records of seats were here considered without a headrest; they may however integrated, or be surmounted by such headrests, which should not reasonably exceed the height limit of the frame 35.

  Figure 13, we note that the armature 35, is mounted in the lower part, 35a, on the corresponding slide 21, to slide.

  It can be only by the sliding of the frame 35 that can be made the sliding of the seat backs 11a in the direction of these rails, the folders then necessarily being fixed to this frame, for example by bolting or riveting the structural part folder.

  FIG. 7, the positions 37a and 37b of the armature 35, that is to say thus of the separation structure 33, positions in each of which this separation structure, and in particular the armature 35 is locked to a part opposite the structural frame 3, thus following a sliding of the file 11 concerned.

  Figure 13, it is the lock 39 which allows these locks. It comprises a movable bolt 41 adapted to releasably engage in one of several orifices of a fixed receiving portion 43 of the structural frame 3, this at least in the two locking positions 37a and 37b.

  In the rear longitudinal locking position 37b, the backrest lla is in its normal rear position. The seat depth is on the other hand quite significantly reduced, and higher, in the locking position before 37a.

  In FIG. 7, it will also be noted that the forward sliding (AVT) of the backrest 11a, beyond the front locking position 37a, is prevented by the abutment 45 formed on the lower face of the roof 5, so that abut against it a part of the separation structure 33, and in particular here the upper transverse bar of the armature 35.

  In the reverse sliding position (position 37b) it is possible for the same separation structure 33 to be able to abut against a rear stop (not shown) of the structure 3 of the vehicle situated for example towards the base of the partition 29.

  Sealing means 47, such as friction pads, are advantageously interposed between the separation structure 33 (here the top of the frame 35) and the lower face 5a facing the roof 5 to ensure a tight sliding (to water and more generally moisture) of the separation structure 33 vis-a-vis the roof 5 and the outside.

  Advantageously, this seal will be extended laterally at the location of the side portions de.toit defining the custodes (area 49 for one of these side portions in Figure 1).

  It will be understood that such a mounting of sliding backs is adaptable to different types of vehicle, whether it is in particular fixed-roof vehicle, for example sedan or minivan, or a vehicle with a convertible roof, that the roof either completely removable (eg hard-top roof) or hinged to the structural frame 3 of the vehicle, rigid roof or soft top.

  With regard to the sliding of the backrests 11a, it could be directly the armature of the seat backs 11a which would be releasably locked relative to the structural frame 3 and thus with respect to the slides 21, this in at least two sliding positions along the runners, and more or less forward or backward relative to the rear storage space 19.

  The rear pivot axis 119a of the cover 107 is situated substantially at the level of the upper part of the rear bumper 59 of the vehicle.

  Note also that, as already indicated: - so we have equipped the structure 33, 35 of separation of a reinforcing armature 35 and security rising above the upper limit of said records lia of seats and s' extending generally transversely to the longitudinal axis X of the vehicle, as well as a rear window 15 also extending generally transversely to the longitudinal axis of the vehicle, towards the rear longitudinal end of the passenger compartment 7, and which has been adapted the longitudinally available space substantially at the location of the rear storage space 19 by sliding, towards the front or towards the rear of the vehicle, the frame 35 and the rear window 15 together with the said folders lia. of the seats concerned, the vehicle has been made accessible by providing it with a movable roof 55 which can occupy a first position in which it covers at least part of the passenger compartment and a second position in which the passenger can at least partly cleared, said roof then being located away from the top of the passenger compartment that it covered in the first position, - and it was made articulable with respect to the structural frame 3 the main cover 107, by pivoting about a pivot axis transverse to the longitudinal axis X of the vehicle by arranging this axis towards the rear of the main cover, and again, to cover with the movable roof 55 or discover at will the cockpit, the movable roof is hingedly mounted to the structural frame of the vehicle between its first and second positions, substantially at a rear position of said partition structure 33, so that the roof can be stored or removed from the rear storage space 19 that the separation structure is in the rear sliding position or in the further sliding position.
