Abstract

The invention relates to a vehicle seat comprising a base frame and comprising a seat frame which can be adjusted relative to the base frame, and comprising a gas spring which acts between this base frame and this seat frame and which is supported against the seat frame, wherein at least one pressure source and at least one valve device which is in fluid connection with this pressure source are provided, and in that furthermore a manually operated actuation element is provided for adjusting the vehicle seat, wherein this at least one valve device is arranged on or in the actuation element.

Claims

1. Vehicle seat, comprising:

a base frame;

a seat frame which can be adjusted relative to the base frame;

a gas spring which acts between the base frame and the seat frame and which is supported against the seat frame;

a manually operated actuation element for adjusting the vehicle seat; and

at least one pressure source and at least one valve device which is in fluid connection with the pressure source, wherein the at least one valve device is arranged on or in the actuation element.

2. The vehicle seat of claim 1, further comprising a seat height adjustment device for displacing the seat frame relative to the base frame in order to adjust the seat height.

3. The vehicle seat of claim 1, further comprising a gas adjustment device for adjusting the gas pressure in the gas spring as a function of the weight of a person sitting on the vehicle seat.

4. The vehicle seat of claim 2, further comprising a gas adjustment device for adjusting the gas pressure in the gas spring as a function of the weight of a person sitting on the vehicle seat.

5. The vehicle seat of claim 1, further comprising a microswitch arranged on or in the actuation element.

6. The vehicle seat of claim 1, wherein the at least one valve device comprises a 2/2-way valve and a 3/2-way valve.

7. The vehicle seat of claim 1, wherein the manually operated actuation element is configurable to pivot about a pivot axle upon actuation.

8. The vehicle seat of claim 1, wherein the manually operated actuation element has a plurality of actuation positions and one neutral position.

9. The vehicle seat of claim 2, wherein the manually operated actuation element has a plurality of actuation positions and one neutral position.

10. The vehicle seat of claim 3, wherein the manually operated actuation element has a plurality of actuation positions and one neutral position.

11. The vehicle seat of claim 5, wherein the manually operated actuation element has a plurality of actuation positions and one neutral position.

12. The vehicle seat of claim 1, wherein the at least one valve device is a solenoid valve having a monoflop control system as protection against overheating.

13. The vehicle seat of claim 2, wherein the at least one valve device is a solenoid valve having a monoflop control system as protection against overheating.

14. The vehicle seat of claim 3, wherein the at least one valve device is a solenoid valve having a monoflop control system as protection against overheating.

15. The vehicle seat of claim 5, wherein the at least one valve device is a solenoid valve having a monoflop control system as protection against overheating.

16. The vehicle seat of claim 1, further comprising an ignition interface for transmission of a signal indicating the change of state of the vehicle from “

Ignition off”

to “

Ignition on,”

which signal triggers an automatic (weight) level regulation.

17. The vehicle seat of claim 2, further comprising an ignition interface for transmission of a signal indicating the change of state of the vehicle from “

Ignition off”

to “

Ignition on,”

which signal triggers an automatic (weight) level regulation.

18. The vehicle seat of claim 3, further comprising an ignition interface for transmission of a signal indicating the change of state of the vehicle from “

Ignition off”

to “

Ignition on,”

which signal triggers an automatic (weight) level regulation.

19. The vehicle seat of claim 5, further comprising an ignition interface for transmission of a signal indicating the change of state of the vehicle from “

Ignition off”

to “

Ignition on,”

which signal triggers an automatic (weight) level regulation.

20. Vehicle seat, comprising:

a base frame;

an adjustable seat frame having a gas spring configured to act between the base frame and the seat frame;

at least one pressure source; and

a manually operated actuation element for adjusting the vehicle seat having at least one valve device in fluid connection with the pressure source.
