  • Pyrotechnic drive unit and method for the production of such a unit
    Patent number: 8596179
    Abstract: A pyrotechnic drive unit includes a cylinder tube (12) having an axial end (28), a piston (14) guided in the cylinder tube (12), a pyrotechnic igniter (16) which is adjacent to the piston (14) and constitutes the pyrotechnic drive, and a plastic part (18). The plastic part (18) is injection-molded to the igniter (16) and to the axial end (28) of the cylinder tube (12) so that it fastens the igniter (16) to the cylinder tube (12) and tightly closes the axial end (28) of the cylinder tube (12), the plastic part (18) engaging the piston (14) in an initial position of the drive unit (10).
