Abstract

A vehicle seat having a seat with a seat frame, a backrest with a backrest frame, the backrest frame being pivotally mounted relative to the seat frame around a first transverse axis between at least one deployed position for receiving a seat occupant and a folded position in which the backrest frame is folded opposite the seat frame. The seat further includes on each side of the seat a first and a second connecting rod intended to be fixed on a support of the seat so as to be pivotable about a respective transverse axis to lift the backrest frame relative to the seat support.

First claim

The invention claimed is:

1. A vehicle seat, comprising a seat with a seat frame, a backrest with a backrest frame, the backrest frame being pivotally mounted relative to the seat frame about a first transverse axis between at least one deployed position for receiving a seat occupant and a folded position in which the backrest frame is folded to a substantially horizontal position opposite the seat frame, the seat further comprising on each side of the seat a first connecting rod and a second connecting rod attached to a seat support so as to be pivotable about a first transverse axis and a second transverse axis, respectively, for raising the backrest frame relative to the seat support from the folded position into a console position of the seat with the backrest frame remaining in a substantially horizontal position, such that an angle between a direction of a back of the backrest frame in the console position and a direction of the back of the backrest frame in the at least one deployed position is greater than or equal to 100° and less than or equal to 115°, wherein the first connecting rod and the second connecting rod are configured so that the backrest frame is at a first distance from the seat support in the folded position and the backrest frame is at a second distance from the seat support in the console position, and wherein the second distance is greater than the first distance.

2. The vehicle seat according to claim 1 , comprising a flange on each side of the seat and a tilting device for inclining the backrest frame relative to the flanges.

3. The vehicle seat according to claim 2 , comprising a latch adapted to lock the position of one or more flanges relative to the seat support of the vehicle seat.

4. The vehicle seat according to claim 3 , wherein the latch is fixed to one of the flame flanges.

5. The vehicle seat according to claim 2 , comprising an actuator for adjusting the angular position of the backrest frame relative to the flanges.

6. The vehicle seat according to claim 2 , wherein the tilting device is discontinuous.

7. The vehicle seat according to claim 2 , wherein, on each side of the seat, the first and second connecting rods are fixed to each side of the seat to the flanges so as to be pivotable about a third transverse axis and a fourth transverse axis, respectively.

8. The vehicle seat according to claim 1 , wherein the seat frame is pivotally fixed to a third connecting rod.

9. The vehicle seat according to claim 1 , further comprising a headrest attached to the backrest frame.

10. The vehicle seat according to claim 9 , wherein the headrest is movable relative to the backrest frame.

11. The vehicle seat according to claim 1 , comprising an actuator for adjusting the angular position of the first and second connecting rods relative to the seat support.

12. A vehicle seat according to claim 1 , further comprising a third connecting rod mounted on the seat support of the vehicle seat pivotally about a third transverse axis, the seat frame being fixed to the third connecting rod, pivotally about a fourth transverse axis.

13. A vehicle seat according to claim 1 , wherein the seat support is or comprises a rail for a slide for attachment for slidable longitudinal adjustment with respect to a floor of a motor vehicle.

14. A motor vehicle comprising a chassis defining a passenger compartment with a floor, and a vehicle seat according to claim 1 , wherein the seat support is the floor or the seat support is secured to the floor.

15. A method of folding a motor vehicle seat from at least one deployed position to a console position, the motor vehicle seat comprising a seat with a seat frame, a backrest with a backrest frame, the backrest frame being pivotally mounted relative to the seat frame about a first transverse axis between the at least one deployed position for receiving a seat occupant and a folded position in which the backrest frame is folded opposite the seat frame, the seat further comprising on each side of the seat a first connecting rod and a second connecting rod attached to a seat support so as to be pivotable about a first transverse axis and a second transverse axis, respectively, for raising the backrest frame relative to the seat support, comprising the steps of:
folding down the backrest frame from the deployed position to the folded position in which the backrest frame is located opposite the seat frame in a substantially horizontal position, and
pivoting the first and second connecting rods to lift the backrest frame relative to the seat support until reaching the console position with the backrest remaining in a substantially horizontal position, wherein the first connecting rod and the second connecting rod are configured so that the backrest frame is at a first distance from the seat support in the folded position and the backrest frame is at a second distance from the seat support in the console position, and wherein the second distance is greater than the first distance.

16. The method of folding a motor vehicle seat according to claim 15 , the motor vehicle seat further comprising a flange on each side of the seat and a tilting device for inclining the backrest frame relative to the flanges, the method further comprising a step of disengaging the tilting device of the backrest frame relative to the flanges.

17. The method of folding a motor vehicle seat according to claim 15 , the motor vehicle seat further comprising a flange on each side of the seat, a tilting device for inclining the backrest frame relative to the flanges, and a latch adapted to lock the position of the relative to the seat support of the vehicle seat, the method further comprising a step of unlocking the latch.

18. The method of folding a motor vehicle seat according to claim 15 , the motor vehicle seat further comprising a flange on each side of the seat and a tilting device for inclining the backrest frame relative to the flanges, the method further comprising a step of engaging the tilting device of the backrest frame relative to the flanges.

19. The method of folding a motor vehicle seat according to claim 15 , further comprising a step of locking the seat in the console position.
