Abstract: A rotary drive for a belt tensioner includes a housing, a pinion rotatably mounted therein, and at least one driving gear coupled to the pinion, the driving gear being mounted in the housing and being adapted to be driven by pressurized gas introduced into a pressure chamber. Formed in the driving gear is a cavity having a substantially radially extending wall which, in the installed state, is opposite to a protrusion which projects into the cavity and is rigidly connected to the housing, the wall of the cavity and the protrusion forming part of a wall of the pressure chamber.

Abstract: A deflection fitting for a safety belt includes a carrier plate (10) having an installation opening (18) and an eye (20) for the safety belt to pass through. The deflection fitting further includes a covering (12) of plastic, adapted to the installation situation of the deflection fitting, to form an edge for the carrier plate (10). The deflection fitting further includes an adapter (14) of plastic having a collar portion (28) inserted into the installation opening (18) and a delimiting portion (30) inserted into the eye (20). The covering (12) is constructed as a component made of a single piece, which surrounds the lower and the lateral outer edge regions of the carrier plate (10).

Abstract: A drive (10) for a belt tensioner includes a housing (24), a piston (20) that is movably accommodated in the housing (24), and a rack (16) having a toothing (14). The rack (16) is arranged outside the housing (24) and has a guide section (18). The guide section (18) is coordinated with a counter guide section that is arranged outside the housing (24).
