Method for producing a pressure-filled bladder, pressure-filled bladder and pneumatic adjustment device for a seat

摘要

Method for producing a bubble (BL) fillable with pressure medium (DM) as an adjusting element (BL1, BL2, BL3) for a seat, in particular vehicle seat (FZS), having the following steps:– producing a preform (VF) in the form of a flat plastic element (FE) by injection molding such that a first part element (TE1) and a second part element (TE2) are connected to each other at least one transition section (UA),-Matching the first part element (TE1) of the flat element (FE) with the second part element (TE2) of the flat element (FE),-Connect the first part element (TE1) to the second part element (TE2) along one or more connecting seams (VN) to create a bubble chamber (BK) that can be filled with pressure medium (DM).
