Abstract

The invention relates to a vehicle seat having a backrest and a seat surface device that forms a seat surface and that is provided with a pad cover, in particular an outer pad cover, wherein the seat depth of the seat surface is adjustable. A seat depth adjustment device facilitates seat depth adjustment, the seat depth adjustment device including a first deflection device for deflecting the seat pad cover in the end region of the seat surface remote from the backrest, a flexible part that is coupled to the pad cover, and at least one second deflection device for deflecting the flexible part, the second deflection device being arranged at a distance from the first deflection device.

Claims

1. An adjustable depth vehicle seat having a backrest and a seat pad cover that defines a seat surface extending between the backrest and an end region remote from the backrest, comprising a seat depth adjustment device having:

a first deflection device for deflecting the seat pad cover in the end region of the seat surface;

a flexible member that is coupled to a first end of the seat pad cover; and

a second deflection device for deflecting the flexible member, the second deflection device being arranged at a distance from the first deflection device,

wherein the first deflection device is formed by at least one non-rotating curved or bent plate section,

wherein the first and second deflection devices are coupled to an operating part,

wherein the operating part is arranged below the first and second deflection devices, such that movement of the operating part causes motion of the seat pad cover and the flexible member about the respective deflection devices.

2. The vehicle seat according to claim 1, wherein the position of the first deflection device is adjustable relative to the backrest for the purpose of seat depth adjustment.

3. The vehicle seat according to claim 1, wherein the first deflection device is configured for a deflection of the seat pad cover through an angle of more than 100°

.

4. The vehicle seat according to claim 1, wherein the position of the second deflection device is adjustable for the purpose of seat depth adjustment.

5. The vehicle seat according to claim 1, wherein the second deflection device is configured for a deflection of the flexible member through an angle of more than 100°

.

6. The vehicle seat according to claim 1, wherein the second deflection device comprises at least one bolt.

7. The vehicle seat according to claim 1, wherein the second deflection device is fixedly connected to the first deflection device.

8. The vehicle seat according to claim 1, wherein the thickness of the seat pad cover substantially tapers from the backrest to the end region remote from the backrest.

9. An adjustable depth vehicle seat, comprising:

a backrest;

a seat surface device having a seat pad cover that defines a seat surface extending between the backrest and an end region remote from the backrest, wherein a first end of the seat pad cover is attached to the backrest; and

a seat depth adjustment device having

a first deflection device for deflecting the seat pad cover in the end region of the seat surface;

a flexible member that is coupled to a second end of the seat pad cover; and

a second deflection device for deflecting the flexible member, the second deflection device being arranged at a distance from the first deflection device,

wherein the first deflection device is formed by at least one a non-rotating curved or bent plate section,

wherein the first and second deflection devices are coupled to an operating part,

wherein the operating part is arranged below the first and second deflection devices, such that movement of the operating part causes motion of the seat pad cover and the flexible member about the respective deflection devices.

10. The vehicle seat according to claim 9, wherein the position of the first deflection device is adjustable relative to the backrest for the purpose of seat depth adjustment.

11. The vehicle seat according to claim 9, wherein the first deflection device is configured for a deflection of the seat pad cover through an angle of more than 100.

12. The vehicle seat according to claim 9, wherein the position of the second deflection device is adjustable for the purpose of seat depth adjustment.

13. The vehicle seat according to claim 9, wherein the second deflection device is configured for a deflection of the flexible member through an angle of more than 100.

14. The vehicle seat according to claim 9, wherein the second deflection device comprises at least one bolt.

15. The vehicle seat according to claim 9, wherein the second deflection device is fixedly connected to the first deflection device.

16. The vehicle seat according to claim 9, wherein the thickness of the seat pad cover substantially tapers from the backrest to the end region remote from the backrest.
