Abstract

The invention relates to a suspension device, in particular for a vehicle seat, comprising an upper suspension part and a lower suspension part, which can be connected to one another by a first swivelling connector and a second swivelling connector, wherein a first spring unit can be connected in a first end region on the one hand by means of an adjusting device to the first swivelling connector and can be connected in a second end region on the other hand to the lower suspension part, wherein by means of the adjusting device the position of the first spring unit can be adjusted in order to adjust the spring force and the spring rate of the suspension device.

First claim

What is claimed is:

1 . A suspension device, in particular for a vehicle seat,
comprising an upper suspension part and a lower suspension part, which can be connected to one another by a first swivelling connector and a second swivelling connector, wherein a first spring unit can be connected in a first end region on the one hand by means of an adjusting device to the first swivelling connector and can be connected in a second end region on the other hand to the lower suspension part, wherein by means of the adjusting device the position of the first spring unit can be adjusted, in order to adjust the spring force and the spring rate of the suspension device.

2 . The suspension device according to claim 1 , wherein the first end region of the first spring unit can be adjusted by means of the adjusting device into position, wherein a position of the second end region is essentially constant.

3 . The suspension device according to claim 1 , wherein the suspension device comprises at least one damper, wherein a first end region of the damper can be connected to the adjusting device.

4 . The suspension device according to claim 1 , wherein the second swivelling connector is designed to be longer than the first swivelling connector.

5 . The suspension device according to claim 1 , wherein the adjusting device comprises a rotary lever which is stationary relative to the first swivelling connector, which rotary lever is rotatably mounted about a first axis of rotation, which is stationary relative to the first swivelling connector, and comprises an adjusting element which can be displaced on displacement along a displacement axis.

6 . The suspension device according to claim 5 , wherein a first lever element is arranged pivotably on the adjusting element by means of a second axis of rotation, wherein a second lever element is arranged pivotably on the first lever element by means of a third axis of rotation and the second lever element is connected pivotably to the first swivelling connector by means of a fourth axis of rotation.

7 . The suspension device ( 1 ) according to claim 5 , wherein the displacement axis corresponds to the first axis of rotation.

8 . The suspension device according to claim 1 , wherein the first spring unit is formed by a spring, wherein preferably the spring is a tension spring.

9 . The suspension device according to claim 5 , wherein the first spring unit is at least connected operatively to the second lever element.
