Abstract
A pyrotechnical drive device for a safety tensioning device has a guide tube and a drive element movably mounted within the guide tube. A receiving member is connected to the guide tube. A gas generator for producing a gas when activated is provided. The gas drives the drive element within the guide tube. The gas generator includes a sleeve and is mounted with the sleeve within the receiving member. The receiving member has a wall with an opening and the opening has a size adapted to the wall thickness material of the sleeves such that, when a pressure load limit of the gas generated within the sleeve is surpassed upon activation of the gas generator, the sleeve is pressed into the opening and bursts open.
