Abstract
The invention relates to a pneumatic support (1) which can be folded together as a result of joints (10) in the pressure member (3) and has a flexible web (12) that is connected to the tractive member (4) over the entire length of the latter and is connected to the pressure member (3) only in the region of the joints of said member (10). This allows the joints (10) to be fixed in such a way that the pressure member (3) does not buckle at the site of the joints and thus remains stable.
