    Abstract: The present invention relates to an ejector clutch (1) for a belt tensioner, comprising a first shaft (10), a second shaft (20), and a coupling part (30), wherein the coupling part (30) is arranged between the first shaft (10) and the second shaft (20) in a longitudinal axis (X) defining an axial direction, wherein the coupling part (30) has at least one clutch finger (40), which engages in a first recess (15) of the first shaft (10) for transmitting a torque (M) and, when a torque (M2) to be transmitted is exceeded, said clutch finger is displaced, against a spring force in the axial direction, from the first recess (15) of the first shaft (10) into a second recess (25) of the second shaft (20). The invention further relates to a belt tensioner with an ejector clutch (1).

    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).

    Abstract: A reversible seat belt tensioner includes an electric motor (2), a belt shaft (1) drivable in the belt winding direction by the electric motor (2) via a drive wheel (10), and a drive shaft (9) transmitting the rotational movement of the electric motor (2) to the drive wheel (10). The drive shaft (9) is connected to at least one of the drive wheel (10) and the electric motor (2) via a helical gear unit. The teeth of the helical gear unit make point-shaped contacts with each other, and the drive shaft (9) is axially movable relative to the electric motor (2) or the drive wheel (10) without disengaging the gear teeth.

    Abstract: A power transmission mechanism (19) for transmitting power from a motor (34) to a spindle (12) having a clutch housing (50), a pawl (41) engageable with the clutch housing (50), a gear wheel (57) which holds the pawl (41) and rotates with the rotation of the motor (34), an outer gear cover (26), and a friction ring (42) engaging with the pawl (41) and held on the outer gear cover (26) by frictional force. The friction ring (42) is provided with a protruding portion (42a) which engages with an engagement groove (41b) of the pawl (41), and a plurality of contact pieces (42b) in contact with an outer peripheral surface of a small diameter ring portion (26c) of the outer gear cover (26) and press radially against the outer peripheral surface towards an inner side The friction ring can be easily coupled to the outer gear cover.
