Abstract

A pneumatic device for the variation of a contour of a seat bearing surface of a vehicle seat is disclosed. The pneumatic device includes a first foil portion, a second foil portion which is connected to the first foil portion along at least one connecting seam such that a bladder for the variation of the contour of the seat bearing surface, having a bladder chamber which can be filled with pressure medium and having an inflow opening for the inflow of the pressure medium, is formed, and a throttle element, which is arranged in the interior of the bladder chamber and which is designed to throttle a pressure medium flow flowing in through the inflow opening.
