The invention relates to a safety belt tensioning device comprising a piston which is guided in a tube and, when triggered, is supplied with a gas produced by a gas generator arranged in a tube section, a lateral section introduced into the tube by a cable opening being connected to said piston. The inventive device is characterised in that the receiving section (12) of the tube (10), receiving the gas generator (16), is staggered in relation to the piston stroke section (11) of the tube (10), receiving the piston (17), by means of a narrowing of the cross-section of the tube (10), having a defined overflow course (29). |
