Abstract

A vehicle seat, in particular for a motor vehicle, is provided. The vehicle seat includes a sitting part with a sitting surface, at least one air bellows arranged in the sitting part for altering the extent of the sitting surface in longitudinal direction of the vehicle seat and a back part. At least one guide element is arranged on the air bellows and is connected with the air bellows, and the guide element is movably mounted on at least one bearing part.

Claims

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

a sitting part with a sitting surface;

at least one air bellows arranged in the sitting part for altering the extent of the sitting surface in longitudinal direction of the vehicle seat; and

a back part,

wherein at least one guide element is arranged on the at least one air bellows and is connected with the at least one air bellows, and the at least one guide element is movably mounted on at least one bearing part.

2. The vehicle seat according to claim 1, wherein the at least one guide element is an eye and the bearing part is a bearing rod.

3. The vehicle seat according to claim 2, wherein a longitudinal axis of the bearing part is aligned substantially in longitudinal direction of the vehicle seat.

4. The vehicle seat according to claim 2, wherein several guide elements are mounted on the bearing part.

5. The vehicle seat according to claim 1, wherein the at least one guide element is mounted with a sliding bearing on the at least one bearing part.

6. The vehicle seat according to claim 1, wherein the at least one guide element is fastened on the upper side on the at least one air bellows, so that the vertical position of the at least one air bellows on the upper side is substantially constant in various filling states of the at least one air bellows.

7. The vehicle seat according to claim 1, wherein the at least one air bellows is constructed on the upper side in the manner of a concertina.

8. The vehicle seat according to claim 1, wherein the at least one guide element is fastened on the lower side on the at least one air bellows so that the vertical position of the at least one air bellows on the lower side is substantially constant in various filling states of the at least one air bellows.

9. The vehicle seat according to claim 1, wherein the sitting part is divided into sitting part elements in transverse direction of the vehicle seat, and an air bellows is arranged in each case between at least two sitting part elements for moving at least one sitting part element in longitudinal direction of the motor vehicle.

10. The vehicle seat according to claim 9, wherein by means of the air bellows on inflating of the air bellows with an air pump, the at least two sitting part elements are movable apart for increasing the extent of the sitting surface in longitudinal direction of the vehicle seat, and by means of at least one elastic element, in particular a spring, the at least two sitting part elements are movable together to reduce the extent of the sitting surface in longitudinal direction of the vehicle seat.

11. The vehicle seat according to claim 1, wherein the at least one air bellows is divided into partial air chambers by at least one dividing wall.

12. The vehicle seat according to claim 1, wherein a movable sitting part is arranged in longitudinal direction of the vehicle seat in front of the at least one air bellows and is connected with the at least one air bellows, and the movable sitting part is constructed as a movable support part, with the at least one air bellows is at least partially arranged beneath the movable support part.

13. The vehicle seat according to claim 1, wherein only one sitting part element is movable in longitudinal direction of the vehicle seat.

14. The vehicle seat according to claim 12, wherein the at least one movable sitting part is movably mounted with a guide track.

15. The vehicle seat according to claim 1, wherein the sitting part of the vehicle seat further comprises two side guide elements and the sitting surface is arranged between the side guide elements.

16. A motor vehicle, comprising:

at least one vehicle seat having a sitting part with a sitting surface, at least one air bellows arranged in the sitting part for altering the extent of the sitting surface in longitudinal direction of the vehicle seat, a back part and at least one guide element arranged on the at least one air bellows and connected with the at least one air bellows, and the at least one guide element is movably mounted on at least one bearing part,

wherein the at least one air bellows is constructed on the upper side in the manner of a concertina.

17. The motor vehicle according to claim 16, wherein the at least one guide element is an eye and the bearing part is a bearing rod.

18. The motor vehicle according to claim 17, wherein a longitudinal axis of the bearing part is aligned substantially in longitudinal direction of the vehicle seat.

19. The motor vehicle according to claim 17, wherein several guide elements are mounted on the bearing part.

20. The motor vehicle according to claim 16, wherein the at least one guide element is mounted with a sliding bearing on the at least one bearing part.
