Abstract

A vehicle seat for a motor vehicle is provided. The vehicle seat includes a seat frame, a backrest and a backrest adjuster having a pivot axis, a first fitting and a second fitting for adjusting an inclination angle of the backrest. The vehicle seat also includes a switch, which activates a drive at particular inclination angles of the backrest, in order to move the vehicle seat forward or backward. The switch is arranged beneath the pivot axis in the outer region of the first fitting.

Claims

1. A vehicle seat for a motor vehicle, comprising:

a seat frame;

a backrest;

a backrest adjuster having a pivot axis, a first fitting and a second fitting for adjusting an inclination angle of the backrest; and

a switch, which activates a drive at particular inclination angles of the backrest, in order to move the vehicle seat forward or backward,

wherein the switch is arranged beneath the pivot axis in the outer region of the first fitting.

2. The vehicle seat according to claim 1, wherein the switch has a sensing element, which detects the inclination angle of the backrest.

3. The vehicle seat according to claim 2, wherein the second fitting has a switching cam in order to switch the switch.

4. The vehicle seat according to claim 3, wherein the sensing element is movable at least approximately parallel to the outer side of the first fitting.

5. The vehicle seat according to claim 4, wherein the sensing element is bent such that its free end is able to be applied on the second fitting.

6. The vehicle seat according to claim 5, wherein the switch is able to be arranged on a carrier element and the carrier element on the seat frame.

7. The vehicle seat according to claim 6, wherein the carrier element has a fastening arrangement for a fabric cover of the vehicle seat.

8. The vehicle seat according to claim 6, wherein the carrier element has a fastening arrangement for a cover facing of the vehicle seat.

9. The vehicle seat according to claim 6, wherein the switch is able to be arranged between the carrier element and the first fitting.

10. The vehicle seat according to claim 1, wherein the switch has a time delay on switching over from one movement direction of the vehicle seat to an opposite movement direction.

11. The vehicle seat according to claim 1, wherein the switch is only able to be activated in an angle range which lies outside a comfort range for a person to sit and rest comfortably.

12. The vehicle seat according to claim 1, wherein the switch is a microswitch.

13. The vehicle seat according to claim 1, wherein the activating angle at which the drive is able to be activated is able to be set on the switch.

14. A motor vehicle, comprising:

a vehicle seat including a seat frame, a backrest, a backrest adjuster having a pivot axis, a first fitting and a second fitting for adjusting an inclination angle of the backrest, a switch, which activates a drive at particular inclination angles of the backrest, in order to move the vehicle seat forward or backward, and the switch is arranged beneath the pivot axis in the outer region of the first fitting,

wherein the switch is able to be arranged on a carrier element and the carrier element on the seat frame.

15. The motor vehicle according to claim 14, wherein the switch is able to be arranged between the carrier element and the first fitting.

16. The motor vehicle according to claim 14, wherein the switch has a time delay on switching over from one movement direction of the vehicle seat to an opposite movement direction.

17. The motor vehicle according to claim 14, wherein the switch is a microswitch.

18. The motor vehicle according to claim 14, wherein the activating angle at which the drive is able to be activated is able to be set on the switch.

19. The motor vehicle according to claim 14, wherein the switch has a sensing element, which detects the inclination angle of the backrest.

20. The motor vehicle according to claim 19, wherein the second fitting has a switching cam in order to switch the switch.
