A method for producing an adjusting device for a vehicle seat has the following steps. A flexible hollow body is molded from a thermoplastic plastic by injection molding, wherein the hollow body forms a pressure medium chamber and has an opening which is surrounded by a connecting portion. Furthermore, a first film is arranged at the opening. In particular, a pressure medium line is inserted between the connecting portion or the opening and the first film. Finally, the first film is connected to the hollow body at the connecting portion of the opening at the connecting seam in order to thereby close off the pressure medium chamber. Because the flexible hollow body is formed in one step, in particular by an injection molding process, the manufacturing complexity is minimized and the robustness of the hollow body is increased.

A pneumatic element including: a first, a second, and a third air chamber which are coupled to one another, the first air chamber being coupled to the second air chamber by a weld joint and the second air chamber being coupled to the third air chamber by another weld joint; and an overflow area, which is arranged within the weld joints along a longitudinal axis of the pneumatic element, for a pneumatic communication between the air chambers. Each of the air chambers has a first state in which a pressure inside the air chambers corresponds to a pressure outside of the air chambers and a second state in which the pressure inside the air chambers is greater than the pressure outside of the air chambers. Furthermore, a flow opening is provided for a pneumatic communication between the overflow region and the second air chamber in the first state.
