Abstract

A pneumatic adjustment arrangement for a vehicle seat. The pneumatic adjustment arrangement has at least one chamber or bladder, which can be filled with a pressure medium, as an adjustment element. Furthermore, the pneumatic adjustment arrangement has a fluid line for the filling and/or evacuation of the chamber. Additionally, the pneumatic adjustment arrangement has a valve device which is provided in the fluid line for volume flow regulation. Finally, the pneumatic adjustment arrangement has a noise absorber which is likewise arranged in the fluid line in order to absorb noise generated in the fluid line. In this way, it is possible to create a pneumatic adjustment arrangement for a vehicle seat, in particular for comfort functions, such that objectionable noises during the execution of the comfort fiction are reduced.
