  • Pretensioner device for a seat belt
    Patent number: 9114780
    Abstract: A piston for a pretensioner device (10) for a motor vehicle seat belt system of a type having a gas generator (17) with the piston (21) guided in a tube (16) that closes a pressure space (20) in the tube (16). The pressure space (20) can be pressurized by the gas generator (17), driving the piston (21) to undergo pretensioning operation transmitted to the seat belt system by a force transmission means. The piston has a dome shaped front side adapted to engage a force transmission element and a skirt forming a sealing lip oriented toward the pressure space. At least one slot is formed in the outer surface of the piston extending axially from the sealing lip. The slot can be enlarged by the material erosion caused by the pressure and/or pressure conditions in the pressure space produced by gas from the gas generator.

  • Tensioning device for a safety belt
    Patent number: 9050941
    Abstract: 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).
