  • Force-limiting device for a safety belt system
    Patent number: 10046734
    Abstract: A reversible seat belt tensioner including a rotationally operable plastic driven gear (1), and a drive moved with a belt shaft of the belt tensioner. At least one coupling pawl (4) is provided on the drive gear, engaging a gearing of the drive gear upon activation of the reversible belt tensioner, and in a load-transmitting position produces a linkage between the driven gear (1) and the drive gear. A support ring (3) made of a material having a greater strength than the driven gear (1) is provided and is connected to the driven gear (1) for with a projection (21, 22) which into a recess (15, 16) of the driven gear (1). The recess (15, 16) positioned such that the coupling pawl (4) is braced against the driven gear (1) via the projection (21, 22) which engages in the recess (15, 16).
