Abstract

A vehicle seat (1) having adjustment kinematics, in particular height-adjustment kinematics (6), with movable rockers (12, 14), in particular for adjusting the height of a seat frame of the vehicle seat (1) relative to a connectable vehicle structure, wherein at least one rocker (14) is mounted rotatably about an axis (A), in particular about an axis (A) of a transverse tube (16), and a toothed segment (18) which is connected to the at least one rocker (14) is provided, wherein the vehicle seat (1) has a drive (20) for moving the at least one rocker (14), and the drive (20) is mounted on a seat frame, in particular on a side part (100) of the seat frame, wherein a pinion (26) of the drive (20) meshes with the toothed segment (18), wherein, by aligning the position of the entire drive (20) relative to the side part (100) by means of a compensating body (200), the pinion (26) is positioned relative to the toothed segment (18) in a manner free from play.

Claims (30)

1. A vehicle seat, comprising:

adjustment kinematics with movable rockers, wherein at least one rocker is mounted rotatably about an axis, and a toothed segment which is connected to the at least one rocker is provided,

wherein the vehicle seat has a drive for moving the at least one rocker, and the drive is mounted on a seat frame,

wherein a pinion of the drive meshes with the toothed segment, wherein by aligning the position of the entire drive relative to the side part via a compensating body, the pinion is positioned relative to the toothed segment in a manner free from play,

wherein at least one rib is provided on a surface of the compensating body that is oriented in the direction of the toothed segment.

2. The vehicle seat as claimed in claim 1 , wherein the adjustment kinematics are height adjustment kinematics.

3. The vehicle seat as claimed in claim 1 , wherein the rockers are configured for adjusting the height of a seat frame of the vehicle seat relative to a connectable vehicle structure.

4. The vehicle seat as claimed in claim 1 , wherein the axis is the axis of a transverse tube.

5. The vehicle seat as claimed in claim 1 , wherein the drive is mounted on a side part of the seat frame.

6. The vehicle seat as claimed in claim 5 , wherein the pinion of the drive is secured to the side part via a bridge and a spacer sleeve, thus forming a closed system of forces.

7. The vehicle seat as claimed in claim 1 , wherein the compensating body has a supporting portion with a bevel.

8. The vehicle seat as claimed in claim 7 , wherein the at least one rib extends over the supporting portion and the bevel.

9. The vehicle seat as claimed in claim 1 , wherein the compensating body is supported on a spacer sleeve, which is arranged behind the toothed segment as viewed from the pinion, or on a crash bolt.

10. The vehicle seat as claimed in claim 1 , wherein the compensating body is manufactured from a plastic.

11. The vehicle seat as claimed in claim 1 , wherein the pinion of the drive is guided through an opening in the side part with a gap being formed.

12. The vehicle seat as claimed in claim 1 , wherein the side part has a through bore and two elongated holes.

13. The vehicle seat as claimed in claim 12 , wherein the drive is mounted by a threaded bolt in a manner free from play in the through bore and by two further threaded bolts in each case one of the two elongated holes on the side part.

14. The vehicle seat as claimed in claim 1 , wherein the drive has a step by step transmission or a geared motor.

15. A vehicle seat, comprising:

adjustment kinematics with movable rockers, wherein at least one rocker is mounted rotatably about an axis, and a toothed segment which is connected to the at least one rocker is provided,

wherein the vehicle seat has a drive for moving the at least one rocker, and the drive is mounted on a seat frame,

wherein a pinion of the drive meshes with the toothed segment, wherein by aligning the position of the entire drive relative to the side part via a compensating body, the pinion is positioned relative to the toothed segment in a manner free from play,

wherein the compensating body has a supporting portion with a bevel,

wherein the at least one rib extends over the supporting portion and the bevel.

16. A vehicle seat, comprising:

adjustment kinematics with movable rockers, wherein at least one rocker is mounted rotatably about an axis, and a toothed segment which is connected to the at least one rocker is provided,

wherein the vehicle seat has a drive for moving the at least one rocker, and the drive is mounted on a seat frame,

wherein a pinion of the drive meshes with the toothed segment, wherein by aligning the position of the entire drive relative to the side part via a compensating body, the pinion is positioned relative to the toothed segment in a manner free from play, wherein the compensating body is clipped in a holding opening of a bridge by at least one clip.

17. The vehicle seat as claimed in claim 16 , wherein in the region of the at least one clip slots are provided in the compensating body.

18. The vehicle seat as claimed in claim 17 , wherein a web is arranged in the region of the clip to reinforce the compensating body.
