Abstract
A pneumatic support comprises a long hollow body, tapering towards the ends and two pressure/tension elements. The hollow body is embodied by a sleeve of gas-tight, flexible, non-stretch material. Said sleeve can be formed from two layers, an external non-stretch, flexible sleeve and an inner gas-tight elastic bladder. The hollow body can be pressurised with compressed gas by means of a valve. The both pressure/tension elements lie along diametrically opposed surface lines of the hollow body on the same and are partly or completely frictionally connected to the hollow body along said surface lines. The ends of the pressure/tension elements are frictionally connected to each other.
