Description

MOTOR VEHICLE COMPRISING AT LEAST ONE REVERSE REAR SEAT

  The present invention relates to automotive vehicles comprising at least one folding rear seat.

  More particularly, the invention relates to a motor vehicle comprising a passenger compartment which has a rear part in which is disposed at least one vehicle seat comprising a seat and a backrest, said seat being adapted to take a normal position of use to receive a passenger, and a folded position to allow the storage of objects in the rear part of the passenger compartment.

  Modularity is an important factor in choosing a car. It must be possible to carry both a high number of occupants while seated in the seats of the vehicle, or large volume cargoes in the rear part of the cabin forming the trunk, while maintaining a volume vehicle. relatively low, for example to maintain the maneuverability of this vehicle.

  Thus, it is common to fold the backrest and / or the seat of the rear seats of the vehicle, when they are not occupied by occupants, to increase the volume of the trunk, if one has a large volume of cargo to be transported. Folding the backrest on the seat does not make it easier, however, to load objects into the trunk of the vehicle.

  The present invention is intended to overcome this disadvantage.

  For this purpose, according to the invention, a motor vehicle is provided which, in addition to the features already mentioned, is characterized in that said rear part of the passenger compartment comprises a platform on which said at least one seat is attached and in that said platform is slidably mounted relative to the passenger compartment of the vehicle.

  Thanks to these arrangements, it is much easier to load and unload cargo at the rear of the vehicle, whether the seat is in its normal position of use or in its folded position.

  In preferred embodiments of the invention, one or more of the following arrangements may also be used: - the platform and said at least one seat are adapted to allow, when the seat is in its folded position, a retraction of said seat in the platform, so that at least part of the backrest and / or the seat forms with the platform a substantially continuous surface adapted for the storage of 'objects; - The seat back further comprises a heluitête adapted, when the seat is in the folded position, to be brought into contact. with the seat forming a portion of the continuous surface adapted for storing objects; the headrest comprises a rear face and a front face and the backrest comprises a rear face and a front face which has an upper part intended to come into contact with an upper face of the seat, and in which the part upper face of the backrest and the front face of the headrest have complementary shapes to that of the upper face of the seat, to allow, when the seat is in its folded position, that the rear faces of the backrest and headrest, and a portion of the upper face of the seat form with the platform said continuous surface adapted for storing objects; the platform is slidably mounted to be moved into a retracted position in which said platform can be disengaged from the passenger compartment to be removed from the vehicle; the vehicle comprises a mechanism for anchoring and releasing the platform relative to the passenger compartment when said platform is in its retracted position; the platform is further slidably mounted to be moved into a retracted position, in which the entire platform is included in the passenger compartment to allow for normal use of the seat and / or storage of objects in the seat. cockpit, and in a loading position in which the platform protrudes out of the passenger compartment of the vehicle to allow the loading of objects; the vehicle comprises a mechanism for locking and unlocking the platform relative to the passenger compartment when said platform is in its retracted position; - The platform is composed of at least one lateral rail 20 slidably mounted on the passenger compartment of the vehicle and a support plate secured to the rail which has at least one recess adapted to receive said at least one seat.

  the seat is mounted on the platform by means of at least one front link, a rear link, a slide disposed in the recess and a profile, the front link having an upper end rotatably mounted on the seat and a lower end rotatably mounted on the platform, the rear link, substantially L-shaped, having a back end rotatably mounted on the backrest, a seat end rotatably mounted on the seat, and an apex rotatably mounted on the platform, and the profile having a pivot point rotatably mounted on the backrest and a fixedly attached base on the slide. Other aspects, objects and advantages of the invention will appear on reading the description of one of these embodiments given by way of non-limiting example. The invention will also be better understood from the drawings in which: FIGS. 1a, 1b, 1c and 1d are perspective views showing an embodiment of the vehicle 10 according to the present invention; FIG. FIGS. 3a to 3f are side views of a seat intended to equip the vehicle according to the invention, FIG. the invention with its raised floor removed from said vehicle.

  In the different figures, the same references denote identical or similar elements.

  FIG. 1a shows a vehicle 1, where the rear door is not shown, in order to be able to fully visualize the inside of the vehicle formed by a passenger compartment 2 having a front part 3 and a rear part 5. The rear part 5 of the cabin is intended to receive at least one rear seat 6 which in the example considered here is arranged so that the rear portion 5 also comprises a storage area 4 objects directly between the rear seat 6 and the door 30 rear of the vehicle.

  The front part 3 of the passenger compartment 2 is, for its part, intended to receive the driver's front seat as well as the front passenger seat and possibly, but not necessarily, a seat or an intermediate row of seats 35 interposed between the rear seat 6 and the driver and passenger front seats. FIGS. 1a to 1d only represent a rear seat 6, the other seats are not shown for legibility purposes, but it is possible according to the invention to provide the rear portion 5 of the passenger compartment 2 two or three separate rear seats and independent of each other or a rear seat extending over almost the entire width of the passenger compartment 2. The rear seat 6 consists of a backrest 7, d a seat 8, and possibly a headrest 9. Figure la represents the rear seat 6 in a normal position of use, namely a position where an occupant can sit in the rear seat 6.

  In this normal position of use of the rear seat 6, also shown in FIG. 3a, the backrest 7 has front faces 71 and rear 72 which extend substantially vertically, while the seat 8 has upper faces 81 and lower 82 which extend substantially horizontally. The headrest 9 also has front 91 and rear 92 faces which extend substantially vertically and in the extension respectively of the front 71 and rear 72 faces of the backrest 7. The vehicle 1 or more exactly the rear portion 5 of the cockpit 2 further comprises a platform 10, located above the bottom or floor 36 of the vehicle 1, and on which is reported the rear seat 6. This platform 10 is slidably mounted relative to the passenger compartment 2 of the vehicle between a retracted position, as shown in Figures 1a, 1b or 1c, in which the entire platform 10 is contained in the passenger compartment 2 of the vehicle, and a loading position, as shown in FIG. Figure 1d, in which a rear portion 1a of the platform extends beyond the passenger compartment 2 of the vehicle so as to allow the loading of objects into the storage area 4 of said rear portion 5 of the cockpit. The platform 10 is slidably mounted relative to the passenger compartment 2 by means of a guiding mechanism which, in the example considered here, is formed by two slides 11 (FIG. 2) each comprising a movable section 11b integral with each other. a corresponding lateral edge 10b of the platform 10 and a fixed profile 11a integral with the passenger compartment 2 of the vehicle, said movable section 11b then being slidably mounted in the longitudinal direction relative to the fixed profile 11a by means of 10 balls interposed between the fixed and movable sections.

  The guiding mechanism may also be formed by two rails (not shown) each disposed on a side edge 10b of the platform. Each rail delimits a housing in which are, for example, housed casters 15 secured to the passenger compartment 2 of the vehicle. Of course, the guiding mechanism can also be interposed between the bottom or floor 36 of the vehicle and the underside of the platform 10.

  Of course, other embodiments of the guiding mechanism may be provided to ensure proper longitudinal guidance of the platform 10 relative to the passenger compartment 2 while allowing said platform to support the loading of heavy objects. and bulky. Similarly, the guiding mechanism can be simply actuated by the user or motorized. The guiding mechanism of the platform 10 with respect to the passenger compartment 2 may also be provided with a locking and unlocking mechanism adapted to be placed for example by the user or automatically in a locking position in which the platform is locked relative to the passenger compartment, for example when the platform is returned to its retracted position, and an unlocking position to allow the platform 10 to be brought from its retracted position to its loading position by the user (figure Id). This locking and unlocking mechanism can be mounted on one of the two slides 11 or rail of the guide mechanism, or on the two rails 11 or 5 rail, and be actuated for example by a button 17 (Figure 1) located on the rear end of one of the two slides 11 or rail.

  In order to increase the volume of the storage area 4 located between the rear seat (s) 6 and the rear door 10 of the vehicle, it is possible to fold one or more rear seats 6 from their normal position of use to a position folded in which the front face 71 of the backrest 7 bears against the upper face 81 of the seat 8 so as to store objects 15 on the rear face 72 of the backrest.

  The platform 10 and the rear seat 6 can also be adapted to allow, when the rear seat 6 is in its folded position, a complete retraction of said rear seat 6 in the platform 10 so that the rear faces 72 , 92 of the backrest 7 and the headrest 9 respectively form together with the upper face 13 of the platform a continuous surface, almost flat, extending in the rear part 5 of the passenger compartment and can receive a volume 25 cargoes. Depending on the configuration of the rear seat 6 and the number of accessories that can equip it, it is also possible, without departing from the scope of the invention, that other parts of the seat 6 form with the upper portion 13 of the plate form a substantially continuous surface capable of receiving a cargo. For example, the front portion of the upper face 81 of the seat 8 of the rear seat 6 may have lateral reinforcements 26 arranged so that the width of the spacing between the two lateral reinforcements 26 is substantially equal to the 35 width of the headrest 9 and that the upper face 81 of the seat 8 at the spacing between the two lateral reinforcements 26 has a shape generally complementary to the front face 91 of the headrest 9. We can also imagine that the seat 8 can slide forward to allow the backrest 7 to fall backwards, so that the upper face of the seat forms a substantially continuous part of the surface can receive a cargo.

  In one embodiment, there can be provided in the platform 10 and for each seat 6, a recess 16 having a width substantially equal to the width of a seat, and a length substantially equal to the height of the backrest, in which each rear seat can come retract independently.

  In the case where the rear part of the passenger compartment is provided with a row of two or three rear seats, it is also possible to have a single recess having a width substantially equal to the width of the platform, and a length substantially equal to the height of each file, and in which all the seats can come to retract. Optionally, this recess 16 may also contain a rear seat in the folded position. One embodiment of the platform and rear seat 6 is given with reference to Figs. 1b, 1c and 1d. In this embodiment, the recess 16 formed on the upper face of the platform 10 comprises a bottom 16a delimited by a rear edge 16b and two side edges 16c, while the front part of the recess 16 also forms the front part. of the platform 10. The recess 16 may nevertheless also include a front edge. Compared to the normal position of use of the rear seat 6 shown in Figure la, Figure lb shows that during the folding of the rear seat 6 to its folded position, the lower part of the backrest 7 moves towards the rear relative to the passenger compartment 2, while the upper part of the backrest 7 tilts forwards. This movement of the backrest 7 makes it possible to avoid any prior manipulation of the seats situated directly in front of the rear seat 6. Simultaneously, the seat 8 is driven in a forward and downward movement so that the seat 6, in its folded position, as shown in Figure lc, is retracted into the platform 10. Due to the relative movement 10 of the backrest 7 and the seat 8 of the rear seat 6, the appuitête 9 can be placed between the side reinforcements 26 (Figures 3a to 3f) forming part of the upper face 81 of the seat 8, so that these lateral reinforcements 26, the rear faces 72, 92 of the backrest 7 and the headrest 9 of the rear seat 15 6 form with the upper portion 13 of the platform 10 a continuous surface generally flat. For concerns, for example aesthetics, this surface may possibly not be perfectly flat and have a curvature. The platform 10 is shown in FIG. 1c in its retracted position, in which it is fully included in the passenger compartment 2.

  Any type of folding seat could be used for the present invention, and a particular embodiment having the advantage of being retractable into the recess 16 of the vehicle platform 1 is shown in FIG. using such a retractable seat, we gain more space compared to the simple action of folding the seat in a sliding platform. Each side of the rear seat 6 is mounted in the recess via at least one forward link 19 comprising an upper end 20 and a lower end 21, and at least one rear link 22, substantially L-shaped. having a top 23, a back end 24 and a seat end 25. The lower end 21 of each forward link 19 is rotatably mounted on the side edge 16a of the recess 16 and the upper end 20 of each forward link 19 is rotatably mounted on the front end of the seat 8 of the rear seat 6, so that the front end of the seat 8 can effect a generally rotational movement, as explained later, relative to the lower end 21 of the rear link 19. The rear link 22 is rotatably mounted at its top 23 on the corresponding lateral edge 16a of the recess 16. The end of the back 24 of the biel rear lette 22 is rotatably mounted on the backrest 7 of the seat 6, and the seat end 25 of the rear link 22 is rotatably mounted on the rear end of the seat 8 of the rear seat 6.

  In the normal position of use of the seat 6, these two rods 19 and 22 are held in position by locking means. The backrest 7 has moreover on each of its two lateral faces a pivot point rotatably mounted on a corresponding section 28. This profile 28 extends substantially in the direction of the seat back 20 in its normal position of use, and may for example have a generally triangular shape with a vertex on which is rotatably mounted the pivot point 27 of the folder, and a base 29 extends in the longitudinal direction of the vehicle, and fixedly attached to a slideway 30 in the platform 10. This slide 30 extends in the longitudinal direction of the vehicle, approximately a length less than the height. backrest 7, and rearwardly relative to the rear seat 6 when it is in its normal position 30 of use. The two slides 30 each comprise a fixed profile 30b directly fixed on the bottom 16a of the recess 16, and a movable section 30a slidably mounted on the fixed profile 30b in the longitudinal direction of the slide. The base 29 of each section 28 is fixedly attached to the movable section 30a associated therewith. In the normal position of use (Figure 2), each slide 30 is locked by a conventional locking and unlocking mechanism not shown. These two locking and unlocking mechanisms of the slides are preferably arranged so that the locking or unlocking of the two rails 30 of the rear seat 6 are performed by a user with a single command.

  Figures 3a to 3f describe in detail the successive steps of the retraction of the seat 6, as shown in Figure 2. Figure 3a shows the rear seat 6 in its normal position of use. The lower end 21 of the front link 19 is rotatably mounted, not on one of the side edges 16c of the recess 16 but on a support 34 directly fixed to the bottom 16a of said recess 16 of the platform 10. .

  The upper end 20 of the front link 19 is in turn always rotatably mounted on the front end of the seat 8. Similarly, the top 23 of the rear link 22 L-shaped 20 is rotatably mounted on the support 34. In this normal position of use of the seat 6, the slide 30 and the top 23 of the rear link 22 are locked.

  By unlocking the top 23 of each rear link 22 and the slides 30, for example with the aid of a simple handle, and pushing the rear face 72 of the backrest 7 forward, as indicated by the double arrow of FIG. 3b, or by pulling the front face of the backrest 7, this backrest is rotated forwards around the backrest end 24 of the rear linkage 22.

  The lower end of the backrest 7, and more specifically, its pivot point 27 is moved backwardly as the profile 28 moves backwards by means of the slideway 30, as shown in FIG. as indicated by the single arrow in Figure 3b.

  As shown in FIG. 3c, as the backrest 7 tilts forward, and the profile 28 moves backward, the back end 24 of the rear link 22 describes a rotational movement towards the rear. rearward, so that the seat end 25 of the rear link 22 describes a movement mainly towards the front, which causes the displacement mainly towards the front of the seat 8 of the rear seat 6. The end 10 before the seat 8 then describes, through the rod before 19 a rotational movement around the lower end 21 of the front link 19.

  Once past a position shown in FIG. 3c o the front link 19 is essentially vertical, and therefore o the front end of the seat has raised relative to the normal position of use of the seat 6, the following the forward rotation of the backrest 7 results in a sag of the seat, as shown in Figure 3d. The seat 8 collapses (FIG. 3e) until its lower face 82 rests at least partly on the bottom 16a of the recess 16.

  In this folded position of the seat 6, shown in Figure 3f, the backrest 7 comes into contact with the seat 8 and, if the seat is provided with a headrest 9, 25 it can come to lodge, possibly after a prior retraction, between the lateral reinforcements 26 of the seat 8 so that the rear seat 6 is fully incorporated in the platform 10. In this folded position, an upper portion of the front face 7 of the backrest 7 and the face before 91 of the headrest 9 are supported on the upper face 81 of the seat 8. The rear seat 6 then almost completely fill the recess provided to receive it. The platform 10 is then in its retracted position.

  It is then possible to unlock the guiding mechanism formed by the slideways 11 and to move the platform 10 to its loading position, as shown in FIG. 1d.

  To do this, it is possible to pull towards the rear of the vehicle, and outside of its passenger compartment, the loading platform constituted by the platform 10 and the retracted rear seat or seats 6, as represented in FIG. , and to use this loading platform to facilitate the loading or unloading of a cargo 10 35. The loading platform can make a predefined length stroke to its loading position o a contact element comes into contact with a stop security (not shown).

  If the user desires, he can further increase the loading volume of the rear part of the vehicle 1 by erasing the safety stop, by activating release means to release the platform 10 of the guiding mechanism which connects it to the vehicle. 2, and completely removing, as shown in Figure 4, the platform 10 and seats 6 folded or not of the vehicle, to store them in a suitable place. For this purpose, the user brings the platform into a so-called withdrawal position in which the platform 10 can be detached from the passenger compartment 2. The user then actuates the release means so as to remove the platform 10 of the passenger compartment 2. Subsequently, the user can return the platform and the bench or the rear seats retracted or not in the platform withdrawal position, and activate anchor means 30 to secure again the platform to the cockpit 2 of the vehicle. The retracted position of the platform may correspond to its loading position or to a position between its retracted and loading positions.
