Abstract

A vehicle seat having a seat bottom comprising a ramp and a stop, a slide comprising a first slide segment and a second slide segment, a movable element capable of being moved relative to the slide, the seat bottom being pivotally mounted relative to the movable element about a pivot axis, an articulation member that is stationary relative to the slide member, and a pivoting connecting rod having a first end that is articulated to the articulation member and a second end able to slide against the ramp during the movement of the movable element on the first slide segment, the pivoting connecting rod being shaped to push against the ramp and cause the rotation of the seat bottom during the movement of the movable element on the second slide segment, the second end of the connecting rod bearing against the stop.

First claim

The invention claimed is:

1. A seat for a vehicle comprising:
a seat back,
a seat bottom connected to the seat back, the seat bottom comprising at least one ramp extending in a longitudinal direction and a stop extending in a transverse direction,
at least one slide extending in the longitudinal direction, the at least one slide comprising a first slide segment and a second slide segment,
at least one movable element capable of being moved in the longitudinal direction relative to the at least one slide, the seat bottom being pivotally mounted relative to the movable element about a pivot axis directed in the transverse direction,
at least one articulation member that is stationary relative to the at least one slide, and
a pivoting connecting rod having at least one first end and one second end, the first end being articulated to the at least one articulation member about an articulation axis directed in the transverse direction, the second end being able to slide against the ramp of the seat bottom during the movement of the at least one movable element on the first slide segment,
the pivoting connecting rod being shaped to push against the ramp and to cause the seat bottom to rotate about the pivot axis, during the movement of the at least one movable element on the second slide segment, the second end of the connecting rod bearing against the stop.

2. The seat of claim 1 , wherein the movement of the at least one movable element, when the at least one movable element is positioned on the first slide segment, pivots the seat bottom about the pivot axis and simultaneously moves the at least one movable element when the at least one movable element is positioned on the second slide segment.

3. The seat of claim 1 , which comprises a plate attached to the at least one slide, the at least one articulation member being attached to the plate.

4. The seat of claim 1 , wherein the at least one articulation member is configured to be attached to a floor of a motor vehicle.

5. The seat of claim 1 , wherein the ramp and the stop are formed by a support comprising a hole wherein the second end of the pivoting connecting rod is able to move.

6. The seat of claim 1 , wherein the first slide segment has a length of between 50 and 180 millimeters, and wherein the second slide segment has a length of between 30 and 70 millimeters.

7. A motor vehicle comprising the seat of claim 1 .

8. The seat of claim 1 , wherein the first slide segment has a length equal to 150 millimeters, and wherein the second slide segment has a length equal to 50 millimeters.

9. The seat of claim 1 , which comprises a single actuator able to move only the at least one movable element, when the at least one movable element is positioned on the first slide segment, and to pivot the seat bottom about the pivot axis and simultaneously move the at least one movable element when the at least one movable element is positioned on the second slide segment.

10. The seat of claim 9 , wherein the actuator is an electric motor, the actuator being able to move the at least one movable element of the second slide segment toward the first slide segment, the actuator and the pivoting connecting rod driving the rotation of the seat bottom about the pivot axis in a clockwise direction and the movement of the seat bottom in the longitudinal direction when the movable element is moved on the first slide segment.

11. The seat of claim 1 , wherein the pivoting connecting rod is made of a flexible material, and wherein the at least one articulation member is able to force the pivoting connecting rod into a position wherein its second end pushes on the ramp and contributes to pivoting the seat bottom about the pivot axis during the movement of the at least one movable element on the first slide segment and on the second slide segment.

12. The seat of claim 11 , wherein the flexible material is made of spring steel.

13. The seat of claim 1 , wherein the pivoting connecting rod comprises at least one pivot leg and a first fastening leg that is bent relative to the pivot leg, the at least one articulation member is shaped to have a first profile delimiting a first housing extending in the transverse direction, the first fastening leg being arranged in the first housing.

14. The seat of claim 13 , wherein the pivoting connecting rod comprises a second fastening leg that is bent relative to the first fastening leg, the at least one pivot leg and the first fastening leg being arranged in a plane, the second fastening leg forming an angle greater than 20° with the plane, and wherein the articulation member is shaped to have a second profile delimiting a second housing extending in the longitudinal direction, the second fastening leg being arranged in the second housing.

15. The seat of claim 13 , which comprises two parallel slides that are distant in the transverse direction, and wherein the pivoting connecting rod has a general U shape having a central support leg, two pivot legs, two first fastening legs and two second fastening legs.

16. The seat of claim 13 , wherein the pivoting connecting rod comprises a second fastening leg that is bent relative to the first fastening leg, the at least one pivot leg and the first fastening leg being arranged in a plane, the second fastening leg forming an angle greater than 40° with the plane, and wherein the articulation member is shaped to have a second profile delimiting a second housing extending in the longitudinal direction, the second fastening leg being arranged in the second housing.

17. The seat of claim 1 , which comprises an anchoring device that is able to lock the pivoting of the seat bottom relative to the at least one movable element, during the movement of the at least one movable element on the first slide segment, the anchoring device being unlocked, during the movement of the at least one movable element on the second slide segment.

18. The seat of claim 17 , which further comprises a control member that is configured to unlock the anchoring device and a controller that is able to transmit an unlocking command to the control member when the seat bottom is moved from the first slide segment toward the second slide segment.

19. The seat of claim 17 , wherein the anchoring device is able to be manually unlocked regardless of the position of the movable element on the first slide segment and on the second slide segment.

20. The seat of claim 17 , wherein the at least one movable element moves only on the first slide segment for the adjustment of the longitudinal position of the seat bottom, the anchoring device being held locked.
