Abstract
The invention relates to a vehicle seat, in particular for commercial vehicles, with an upper part and a lower part and with at least one air spring which exerts a resilient effect on a height-distance-movement which changes between the upper and lower parts, and with at least one damper element which damps the changing height-distance movement, wherein the air spring is connected at an air spring outlet to an adjustment device which adjusts a degree of damper hardness, which damps the changing height-distance-movement, wherein the air spring is connected at an air spring outlet to an adjustment device for adjusting a degree of damper hardness of the damper element, wherein the degree of damper hardness can be adjusted and changed by means of an air pressure of the air spring.
Claims8
A vehicle seat, comprising:
- an upper part;
- a lower part;
- at least one air spring, wherein the at least one air spring exerts a resilient effect on a height-distance-movement which varies between the upper and lower parts;
- and
- at least one damper element, wherein the at least one damper element damps the varying height-distance-movement,
- wherein the air spring is connected at an air spring outlet to an adjustment device for adjusting a degree of damper hardness of the damper element,
- wherein the degree of damper hardness being adjustable and variable by means of an air pressure of the air spring,
- wherein the adjustment device is a swivelling lever arm which is attached to the damper element and whose instantaneous swivel position is assigned to a degree of damper hardness of the damper element.
