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

Foldable pneumatic support

Disclosed is a support structure comprising a tension-compression element () which is composed of tension-compression bars () that are connected in real joints () as well as tension straps () that extend from one joint () to another (). The outermost tension-compression bars () are connected in one respective knot (). Two pressurized hollow members that are surrounded by a cover () are arranged on both sides of a plane that extends through the tension-compression element () such that the linear tensions &#x3c3; generated in the cover () preload the tension straps () on the plane of the tension-compression element (), secure the tension-compression bars () against bending, and stabilize the joints (). The linear tensioning components that extend perpendicular to said plane of symmetry strut the tension-compression element () against lateral bending. Air-tight, optionally elastic pneumatic elements () can be inserted into the hollow members ().
