Abstract
A rotary power element for tensioning devices of safety mechanisms for protecting the occupants of vehicles by the use of safety belts has a rotatable drive mechanism, a compress-gas generator, and a tubular element between the drive mechanism and the compressed-gas generator. Also, the element includes at least one preformed acceleration member arranged in the tubular element. This member is capable of being driven forward against the drive mechanism under the action of compressed gas produced by said compressed-gas generator to accelerate the drive mechanism.
