摘要： A rotational tensioning device for a safety belt of a motor vehicle has a reeling device with reeling shaft and a drive wheel connected to the reeling shaft. The drive wheel has a circumference with semi-spherical recesses. A channel, having a first and a second end, is positioned in a plane parallel to the drive wheel. It extends at least over a portion of the circumference of the drive wheel. Spherical mass bodies are contained in the channel. A gas generator is connected to the first end of the channel, wherein, upon activation of the gas generator, a gas is released into the channel for accelerating the spherical mass bodies in the channel and driving the spherical mass bodies through the channel into the semi-spherical recesses to thereby drive the drive wheel and the reeling shaft in a direction of winding of the safety belt. A drive piston, for driving the spherical mass bodies, consists of two of the spherical mass bodies fixedly connected to one another to form a twin ball. The drive piston is positioned within the first end of the channel.

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).

摘要： 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.

摘要： A pretensioning device (10) for a safety belt, of a motor vehicle, having a gas generator (17), a piston (21) guided in a tube (16), which closes a pressure area (20) in the tube (16) that is pressurized by the gas generator (17) whereupon the piston (21) is able to move in a pretensioning movement which is able to be conveyed to the safety belt by means of an inertia body (19a) resting on a front face (9) of the piston (21). The piston (21) forms a pass-through opening (1) releasable upon exceeding of a predetermined pressure and a recess (26) is provided in the front face (9) with an inertia body (19a) resting thereon, so that a flow connection is created from the pass-through opening (1) to the area (25) located behind the piston (21) in the direction of the pretensioning movement (S).
