Abstract

A device for level regulation and level stabilization of a vehicle seat upper part. The device includes an air spring that spring loads a movement of the vehicle seat lower part and of the vehicle seat upper part relative to one another, the vehicle seat lower part and the vehicle seat upper part are arranged in a non-deflected state at a predeterminable distance from one another. The air spring is fluidically connected to a working volume of an additional volume module. A control unit decreases the volume of the working volume in the event of an increase in the distance and increases the volume of the working volume in the event of a decrease in the distance such that the pressure in the air spring can be changed such that the distance between the vehicle seat upper part and a reference surface is substantially unchanged.
