Abstract
A vehicle seat includes a height-adjustable seat frame which has at least two seat frame parts which can be moved relative to one another and at least one gas spring arranged between the seat frame parts for height adjustment purposes. The seat includes a control device that acts upon the gas spring and includes a valve device attached to a first seat frame part and has control valves for actuating gas flows for the gas spring. A control link on a second frame part actuates the control valves, so that a predefinable height of the vehicle seat is ensured regardless of a weight load on the vehicle seat. Movement of the control link relative to the second seat frame part brings about a height adjustment of the vehicle seat.
