[0030] The present invention is described in connection with Figure 1 and Figure 6 the orthogonal (X, Y, Z) coordinate system shown. In the longitudinal direction X, the horizontal direction is understood to extend between the front and rear of the vehicle. The lateral direction Y refers to the horizontal direction extending from one side of the vehicle to the other side of the vehicle. The vertical direction Z refers to the direction perpendicular to the longitudinal direction X and the lateral direction Y.

[0031] In the following description, spatial orientation indicators such as rear, front, top, bottom, front, rear, upper, lower, horizontal, vertical, etc. should be interpreted according to the normal use position of the seats in the vehicle. Specifically, the orientation with respect to the front and rear is relative to the typical use position of the vehicle and the typical position of the seats in the vehicle. The front is the direction in which the vehicle travels forward. ​​​​​​​​

[0032] Figure 1 Shows an example set of seats 2 according to the second embodiment. It includes a first rear seat 4 and a second rear seat 6. In the example shown, the set of seats 2 is arranged in the second row of a motor vehicle 7. The first rear seat 4 is located behind the driver's seat 8. The second rear seat 6 is located behind the front passenger seat 10. According to another embodiment not shown in the present application, the first rear seat may be located behind the driver's seat, while the second rear seat may be located behind the front passenger seat. According to a variant not shown, a set of seats 2 is arranged in the third row of the motor vehicle.

[0033] The set of seats 2, the driver's seat 8 and the front passenger seat 10 are designed to be mounted on the vehicle floor 11.

[0034] In the embodiment shown, the first rear seat 4 is a bench for two passengers. Alternatively, the bench may be replaced by two seats.

[0035] The first rear seat 4 has a seat cushion 12 and a backrest 14. The backrest 14 includes a front face 16 capable of receiving the occupant's back and a back face 18 opposite to the front face 16.

[0036] For the sake of illustration, a first transverse plane (Y1, Z1) is defined as being perpendicular to Figure 1 the longitudinal direction X of the vehicle shown in, and the first transverse plane (Y1, Z1) includes the front face 16 of the backrest 14 of the first rear seat 4. If the front face 16 of the backrest 14 of the first rear seat 4 is tilted backward, the first transverse plane (Y1, Z1) is the plane including the lower edge of the front face 16. For the sake of illustration, a second transverse plane (Y2, Z2) is also defined as being perpendicular to the longitudinal direction X of the vehicle, and the second transverse plane (Y2, Z2) includes the back face of the backrest 14 of the first rear seat 4. If the back face 18 of the backrest 14 of the first rear seat 4 is tilted backward, the second transverse plane (Y2, Z2) is the plane including the upper edge of the back face 18.

[0037] The vehicle 7 includes a false floor 20 arranged behind the second transverse plane (Y2, Z2). In other words, the false floor 20 is arranged behind the first rear seat and the second rear seat. The false floor 20 and the cockpit together define a storage space 21 commonly referred to as a trunk.

[0038] The second rear seat 6 includes a seat cushion 22 and a backrest 24, as Figure 3 shown.

[0039] The seat cushion 22 includes a base, a support structure carried by the base, and a layer of foam attached to the support structure.

[0040] The backrest 24 includes a central support member 26 and side uprights 28 that support the central support member. The central support member 26 includes a frame and a layer of foam attached to the frame. The central support member 26 is adapted to receive the back of an occupant.

[0041] The seat cushion 22 of the second rear seat is mounted to be translatable relative to the first rear seat 4 in the longitudinal direction X. In other words, the seat cushion 22 of the second rear seat is mounted to be translatable relative to the backrest 24 of the second seat in the longitudinal direction X.

[0042] To this end, the set of seats 2 includes a first slideway 30, which is intended to be supported by the false floor 20. The first slideway 30 extends in the longitudinal direction X. The first slideway 30 is Figure 3 shown schematically in. Each first slideway includes a first slideway element 32 integral with the seat cushion base and a second slideway element 34 intended to be carried by the false floor 20. The first slideway element 32 slides relative to the slideway element 34.

[0043] Thus, the seat cushion 22 of the second rear seat is adapted to slide between Figure 2 the use position shown in solid lines in and Figure 2 the retracted position shown in dashed lines in. In Figure 2 and Figure 4 the use position shown in, the backrest 14 of the second seat is aligned with the backrest 24 of the first rear seat in the transverse direction Y. This position corresponds to the typical position of the rear seat. In Figure 2 and Figure 5 the retracted position shown in, the seat cushion 22 is located on the false floor 20, thereby releasing space in the second row of seats. When the vehicle has a trunk floor 35, the seat cushion 22 is advantageously stored between the false floor 20 and the trunk floor 35.

[0044] Thus, advantageously, the seat cushion 22 of the second rear seat can be retracted, thereby providing more space for passengers. This space can be used either for storage or to release space in order to move the front (passenger and / or driver) seat further rearward and / or tilt it (when it is moved to its maximum rear position).

[0045] Preferably, the backrest 24 of the second rear seat 6 is mounted to be translatable relative to the first rear seat 4 in the longitudinal direction X. To this end, each first slideway 30 includes a third slideway element 38, as Figure 3 shown in. The second slideway element 34 is slidable relative to the third slideway element 38 in the longitudinal direction X. The lower part of the side upright 28 of the seat backrest is integral with the second slideway element 34. The lower part of the second slideway element 34 extends in the longitudinal direction X for a length that at least corresponds to the length of the displacement stroke of the seat cushion 22.

[0046] The third slide element 34 has the shape of a guide rail. It is intended to be attached to the false floor 20. The side posts 28 of the backrest are arranged on either side of the seat cushion 22.

[0047] The backrest 24 of the second rear seat is adapted to slide between Figure 4 the illustrated use position and Figure 5 the illustrated retracted position. In the use position, the backrest 24 of the second rear seat is aligned with the backrest 14 of the first rear seat 4 in the transverse direction Y. In the retracted position, the backrest of the second rear seat is behind the second transverse plane (X2, Y2). Advantageously, the space normally occupied by the backrest of the second rear seat is available for passengers. Moving the backrest provides additional space, as Figure 5 illustrated.

[0048] In this embodiment, the first slide element 32 is driven in translation by a first actuator. The second slide element 34 is driven in translation by a second actuator separate from the first actuator.

[0049] In a variant not shown, the group of seats 2 includes two pairs of first slides. Each first slide includes a first slide element attached to the seat cushion base and a second slide element for attachment to the underlying floor. Each second slide includes a first slide element integral with the lower part of the side post 28 and a second slide element for attachment to the underlying floor. The second slide elements of the first and second slides are, for example, in the form of guide rails. The first slides are arranged between the second slides. The side posts 28 of the backrest are arranged on either side of the seat cushion.

[0050] In this variant, the first slide element of the first slide is driven in translation by a first actuator. The first slide element of the second slide is driven in translation by a second actuator separate from the first actuator.

[0051] Referring Figure 1 , the motor vehicle 7 further includes a first guide rail 40 supported by the floor 11 and extending in the longitudinal direction X. The front passenger seat 10 is slidably mounted on the first guide rail 40. The motor vehicle 7 further includes a second guide rail 42 supported by the floor 11 and extending in the longitudinal direction X, and an armrest 44 including at least one slider sliding in the second guide rail 42.

[0052] The second guide rail 42 is attached to the floor between the driver's seat 8 and the passenger seat 10.

[0053] When the backrest and seat cushion of the rear seat are in the retracted position, the front passenger seat 10 and the armrest 44 can advantageously be moved rearward.

[0054] Figure 7Shows an example set of seats 46 according to the second embodiment. This set of seats 46 is designed to be installed in a vehicle 49 of the minivan or SUV (Sports Utility Vehicle) type. In this type of vehicle, the false floor 20 is at the same height as the floor 11 and is continuous with the floor 11.

[0055] Technical elements of the second embodiment that are the same as or similar to those of the first embodiment have the same reference numerals and will not be disclosed again.

[0056] This set of seats 46 includes a first rear seat 4 and a second rear seat 48. The second rear seat 48 includes a seat cushion 50 and a backrest 52. The first rear seat 4 and the second rear seat 48 are supported by the floor 11.

[0057] The second rear seat 48 is adapted to slide relative to the first rear seat 4 in the longitudinal direction X of the vehicle. For this purpose, this set of seats 46 includes two first guide rails 54, which are intended to be supported by the floor and the false floor. The two first guide rails 54 extend in the longitudinal direction X. The base of the seat cushion 50 of the second rear seat has a slider 56 that slides in the first guide rails 54. The base of the seat cushion 50 of the second rear seat includes two slots 58 that extend in the longitudinal direction X. The backrest 52 of the second rear seat includes a central support 60 for receiving the occupant's back and side uprights 62 that carry the central support. The lower part of the side uprights includes a slider 64, and the slider 64 is arranged in the slot 58 in the seat cushion of the second seat. In this embodiment, the same actuator can be used to move the seat cushion 50 and the backrest 52. A stop 63 attached to the side wall of the trunk holds the seat back in front of the slot 58.

[0058] In Figure 7 the retracted position shown by the dashed line, the seat cushion 50 and the backrest 52 are accommodated behind the second transverse plane (Y2, Z2), in the space usually used for storing items.

[0059] In this embodiment, the front passenger seat 10 is slidably mounted in the first guide rails 54. For this purpose, the base of the seat cushion of the front passenger seat 10 includes a slider that slides in the first guide rails 54.

[0060] In a variant not shown, the second seat is arranged behind the driver's seat. According to this variant, the two first guide rails 54 are attached to the sides of the driver's seat, and the driver's seat is slidably mounted on the two first guide rails 54. The second seat is slidably mounted on the same two first guide rails 54.

[0061] Preferably, the front driver's seat 8 or the passenger seat 10 can slide on the first guide rails 54 to a position where the front seats 8, 10 are aligned with the first rear seat 4. Then, the backrest 22 and the seat cushion 24 of the second rear seat are in the retracted position to allow the front seats to be positioned in the normal position of the rear seats.

[0062] If the backrest and / or seat cushion of the first rear seat 4 can also be translated between the use position and the retracted position, the seat cushion of the second rear seat can be translated relative to the first rear seat in its use position. The use position is the conventional position of the seat on which an occupant can sit. Similarly, if the backrest and / or seat cushion of the first rear seat 4 can also be translated between the use position and the retracted position, the backrest of the second rear seat can be translated relative to the first rear seat in its use position.
