Abstract

Vehicle seat comprising a vehicle seat top part, a vehicle seat bottom part and a guide device for guiding the vehicle seat top part with respect to the vehicle seat bottom part when the vehicle seat top part is deflected relative to the vehicle seat bottom part.
The guide device includes a first assembly having a first lever element, a second lever element and a lever element connector. The first lever element and the second lever element are arranged so as to extend forwards in a longitudinal direction.
The guide device also includes a second assembly having a third lever element, a fourth lever element and the lever element connector. The third lever element and the fourth lever element are arranged so as to extend backwards in a longitudinal direction.
The guide device further includes a stabilization device having a fifth lever element, a sixth lever element and a seventh lever element, which are pivotally connected by means of a shared pivot axis. The fifth lever element is pivotally connected to the vehicle seat top part, the sixth lever element is pivotally connected to the vehicle seat bottom part and the seventh lever element is pivotally connected to the lever element connector.

First claim

What is claimed is:

1. A vehicle seat comprising a vehicle seat top part, a vehicle seat bottom part and a guide device for guiding the vehicle seat top part with respect to the vehicle seat bottom part when the vehicle seat top part is deflected relative to the vehicle seat bottom part,
wherein
the guide device comprises:
a first assembly having a first lever element, a second lever element and a lever element connector, the first lever element and the second lever element being arranged so as to extend forwards in a longitudinal direction;
a second assembly having a third lever element, a fourth lever element and the lever element connector, the third lever element and the fourth lever element being arranged so as to extend backwards in a longitudinal direction;
a stabilization device having a fifth lever element, a sixth lever element and a seventh lever element, which are pivotally connected by means of a shared pivot axis;

the fifth lever element being pivotally connected to the vehicle seat top part, the sixth lever element being pivotally connected to the vehicle seat bottom part and the seventh lever element being pivotally connected to the lever element connector.

2. The vehicle seat according to claim 1 , wherein the first lever element is pivotally connected to the vehicle seat bottom part by means of a first pivot axis and the second lever element is pivotally connected to said vehicle seat bottom part by means of a second pivot axis, and the third lever element is pivotally connected to the vehicle seat top part by means of a third pivot axis and the fourth lever element is pivotally connected to said vehicle seat top part by means of a fourth pivot axis.

3. The vehicle seat according to claim 2 , wherein the fifth lever element is pivotally connected to the vehicle seat top part by means of the third pivot axis.

4. The vehicle seat according to claim 2 , wherein when the vehicle seat top part is in a non-deflected position, the third pivot axis is arranged above the first pivot axis and the fourth pivot axis is arranged above the second pivot axis when viewed in a height direction.

5. The vehicle seat according to claim 1 , wherein the first lever element, the third lever element and the lever element connector are pivotally connected by means of a fifth pivot axis, and the second lever element, the fourth lever element and the lever element connector are pivotally connected by means of a sixth pivot axis, and the seventh lever element being pivotally arranged by means of the sixth pivot axis.

6. The vehicle seat according to claim 1 , wherein the sixth lever element is pivotally connected to the vehicle seat bottom part by means of a seventh pivot axis.

7. The vehicle seat according to claim 6 , wherein when viewed in the longitudinal direction, the seventh pivot axis is arranged between the first pivot axis and the second pivot axis.

8. The vehicle seat according to claim 1 , wherein a suspension unit is provided, which is connected to the vehicle seat top part and the vehicle seat bottom part.

9. The vehicle seat according to claim 1 , wherein the lever element connector is designed such that the length of the lever element connector can be changed by the deflection of the vehicle seat top part.

10. The vehicle seat according to claim 1 , wherein the fifth lever element is designed such that the length of the fifth lever element can be changed by the deflection of the vehicle seat top part.
