摘要： A method of producing a device containing pyrotechnical material comprises the following steps: providing a tubular housing element with a base and metal ducts incorporated in the base, with the housing element and the base being integrally formed of glass and the housing element and the base defining a housing interior with a bottom adjoining the base, and the metal ducts extending through the bottom into the housing interior; applying a metal layer on the bottom by forming a heat-generating element integrally connected with the metal ducts and the bottom; introducing the pyrotechnical material into the housing element; and sealing the housing element by heating and melting off. The device obtainable in this way serves for use in vehicle occupant restraint systems, for instance as an igniter in gas generators and belt tensioners.

摘要： A linear drive (10) for a belt tensioner has a cylinder tube (20) comprising at one axial end a face wall (33) provided with an opening (34). A piston (22) is arranged shiftably in the cylinder tube. The piston has a hollow inner space (24). A pyrotechnical propellant charge (28) is provided which following its ignition acts upon the inner space (24) of the piston (22) with compressed gas. To provide a cooling and a filtering function, a pad (44) of a wire conglomerate is arranged within the cylinder tube adjacent the face wall (33) of the cylinder tube.
