Vehicle seat with pneumatic suspension with automatic weight adjustment

摘要

The invention relates to a so-called pneumatic seat for vehicles, in which the internal operating pressure of the pneumatic spring can be increased or lowered by means of a valve controlled by switching cams. The object of the invention is not only to ensure that the internal operating pressure is maintained in an economical fashion after automatic weight adjustment but also to obtain a high service life of the valve and thus of the pneumatic seat. This object is achieved in that the valve and/or the switching cams can be uncoupled from one another. <IMAGE>
