The drive device of lightweight construction for restraining systems in motor vehicles, in particular safety-belt tightening means, comprises a pyrotechnical gas generator, the gases of which act on a working chamber. The working chamber comprises an outwardly leading relief path which is sealed by a closure element of a material which at a temperature which lies above the operating temperature range of the gas generator but which at the most is equal to the self-igniting temperature of the gas generator softens at least to such an extent that the closur...
A drive device for restraining systems in motor vehicles comprising a working chamber and a pyrotechnical gas generator, which, when energized, produces gas with an operating temperature and acting on said working chamber, said working chamber comprising an outwardly leading relief and a closure element sealing said relief path and consisting of a material which at a temperature exceeding said operating temperature but not exceeding a self-igniting temperature of said gas generator softens at least to such an extent that said closure element on self-igni...
