Abstract
A vehicle seat has a scissor-type stand vibratable and adjustable in height, with a pneumatic spring and cranks intersecting at a scissor shaft, and a control device for level control and height adjustment of the stand. The control device has a driver, a switching element coupled with the driver, and a valve device controlled by the switching element, for controlling the pneumatic spring. The driver and the valve device are kinematically assigned to different parts of the stand, such parts being movable relative to one another. The switching element is spaced from the shaft and rotatably supported on the first crank. The valve device is connected with the first crank, and the driver is configured as a Bowden cable, the core of which is coupled with the switching element, and the jacket of which is fixedly connected with the second crank.
