    摘要: A tensioning device (10) for a seat belt, in particular in a motor vehicle, having a gas generator (17) and a piston (21) guided in a tube (16) that closes a pressure space (20) in the tube (16), whereas the pressure space (20) can be pressurized by the gas generator (17), as a result of which the piston (21) can be driven to perform a tensioning operation which can be transmitted to the seat belt by means of the force transmission means. The piston (21) having a closed or constricted opening (1, 1a), and the opening (1, 1a) can be enlarged and/or opened by the material erosion caused by the pressure and/or pressure conditions in the pressure space (20).
