Abstract: A device provides a pneumatic pressure medium via a pressure medium source for at least one pressure medium chamber in particular of a vehicle seat of a motor vehicle. The device has a pressure medium source for the pressure medium and a pressure medium line disposed between the pressure medium source and at least one valve. At least one connection for a pressure medium line is disposed between the valve and the pressure medium chamber. A control module actuates the pressure medium source and the at least one valve. The device further has a housing. A motor of the pressure medium source is located between the control module and a pump of the pressure medium source.

Abstract: A pneumatic device for adjusting a contour of a seating face of a vehicle seat is disclosed. The pneumatic device includes a first foil; a second foil arranged on the first foil; a third foil arranged on the second foil; a first seam connecting the first foil, the second foil and the third foil to one another, wherein the first seam is configured to provide a first fluid chamber between the first foil and the second foil, a second fluid chamber between the second foil and the third foil, and wherein the first fluid chamber and/or the second fluid chamber are configured to adjust the contour of the seating face of the vehicle seat. The pneumatic device further includes a connection passage formed in the second foil and configured to fluidly connect the first fluid chamber with the second fluid chamber.
