Abstract

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.
