In the illustrated example, this seat assembly 2 is arranged in a second row of a motor vehicle 7. The first rear seat 4 is here located behind a driver's seat 8. The second rear seat 6 is here located behind a front passenger seat 10. According to another embodiment not illustrated in the application, the first rear seat could be located behind the driver's seat and the second rear seat could be located behind the front passenger seat. According to a variant not illustrated, the seat assembly 2 is arranged in a third row of a motor vehicle.

[0021] The set of seats 2, the driver's seat 8 and the front passenger seat 10 are intended to be mounted on a floor 11 of a vehicle.

[0022] In the embodiment shown, the first rear seat 4 is a bench seat intended for two occupants. Alternatively, this bench seat can be replaced by two seats.

[0023] The first rear seat 4 comprises a seat 12 and a backrest 14. The backrest 14 comprises a front face 16 intended to receive the back of an occupant, and a rear face 18 opposite the front face 16.

[0024] For the purposes of this description, a first transverse plane (Yl, Zl) is defined such that it is perpendicular to the longitudinal direction X of the vehicle illustrated in [Fig.l] and such that the first transverse plane (Yl, Zl) contains the front face 16 of the backrest 14 of the first seat 4. If the front face 16 of the backrest 14 of the first seat 4 is inclined towards the rear, the first transverse plane (Yl, Zl) is the plane containing the lower edge of the front face 16. For the purposes of this description, a second transverse plane (Y2, Z2) is also defined such that it is perpendicular to the longitudinal direction X of the vehicle and such that the second transverse plane (Y2, Z2) contains the rear face of the backrest 14 of the first seat 4. If the rear face 18 of the backrest 14 of the first seat 4 is inclined backwards, the second transverse plane (Y2, Z2) is the plane containing the upper edge of the rear face 18.

[0025] The vehicle 7 comprises 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 delimits with the cabin a storage space 21 generally called a trunk.

[0026] The second rear seat 6 comprises a seat 22 and a backrest 24 shown schematically in [Fig.3].

[0027] The seat 22 comprises a base, a supporting structure carried by the base and a layer of foam fixed to the supporting structure.

[0029] The seat 22 of the second rear seat is mounted to move in translation in the longitudinal direction X relative to the first rear seat 4. In other words, the seat 22 of the second rear seat is mounted to move in translation relative to the backrest 24 of the second seat in the longitudinal direction X.

[0030] For this purpose, the set of seats 2 comprises first slides 30 intended to be carried by the false floor 20. The first slides 30 extend in the longitudinal direction X. The first slides 30 have been illustrated schematically in [Fig. 3]. They each comprise a first slide element 32 secured to a base of the seat and a second slide element 34 intended to be carried by the false floor 20. The first slide element 32 is sliding relative to the second slide element 34.

[0031] The seat 22 of the second rear seat is thus adapted to slide between a position of use illustrated in solid lines in [Fig. 2] and a retracted position illustrated in dotted lines in [Fig. 2]. In the position of use illustrated in Figures 2 and 4, the backrest 14 of the second seat is aligned with the backrest 24 of the first seat in the transverse direction Y. This position corresponds to a usual position of a rear seat. In the retracted position illustrated in Figures 2 and 5, the seat 22 is arranged on the false floor 20, freeing up a space in the second row of seats. When the vehicle has a trunk bottom 35, the seat 22 is advantageously stored between the false floor 20 and the trunk bottom 35.

[0032] Thus, advantageously, the seat 22 of the second rear seat can be retracted to offer passengers more space. This space can be used either for storage or to free up space to move back and / or tilt the front seat (passenger and / or driver) more, when the latter is moved to a maximum rearward position.

[0033] Preferably, the backrest 24 of the second rear seat 6 is mounted to be movable in translation relative to the first rear seat 4, in the longitudinal direction X.
