For loss-free deflection of the gases generated by a gass generator (22) in a drive unit for a restraining system for vehicle occupants, the connecting passage comprising a deflection is formed between the outlet (24) of the gas generator (22) and a space (26) beneath the piston (16) of a Piston/cylinder drive free from discontinuities at which reflections of the pressure wave generated could occur. The connecting passage consists of two straight passage portion (30, 32) extending inclined to the axis of the gas generator (22) and a curved portion which connects said portions and which is formed by a concave recess (34) in the bottom of the bore (20) into which the gas generator (22) is inserted.
