Abstract
A control element for a vehicle seat includes a bladder configured to be filled with a pressure medium and which includes first and second films connected together along a connecting seam to form a bladder chamber. The connecting seam may have a shape of a polygon, e.g., a square or rectangle, with rounded corners, wherein the sides connecting the corners are curved in a concave manner toward the interior of the polygon. The shape of the connecting seam and thus the shape of the resulting bladder chamber may prevent or reduce the occurrence of constrictions and/or kinks when filling the bladders, which may ensure a reliable and durable operation of the control element.
