Abstract
A drive device includes a piston guided linearly in at least one pressure tube. The drive for the piston includes a plurality of pyrotechnic drive cartridges ignitable in succession, and is especially useful for tightening a seat belt in a motor vehicle. The linear movement of the piston, urged as a result of an initial ignition, triggers subsequent ignitions for driving the piston. The drive cartridges are ignited in succession.
