The invention relates to a drive unit for a safety belt tensioner which has a drive which can be triggered on the response of an acceleration sensor and which can be rotationally fixedly coupled to the belt winding reel. The drive is located in a drive chamber which is formed by two plates, which extend parallel to one another and which are provided with a coating material, and which has a drive band of which at least one end is fastened to a drive shaft.

Drive unit for a safety belt tensioner

A safety belt apparatus for motor vehicles. The apparatus includes a safety belt and a belt tensioner which can be mounted to the vehicle in the region of a free belt section and which cooperates with the safety belt in the region of the free belt section to alter the effective length of the safety belt.

Safety belt apparatus

A belt winder for safety belts has a spindle (,) for the winding up of the safety belt (,) and a rotatable latching flange (,) which can be latched with respect to a fixed base frame (,). A torsion bar (,) is rotationally fixedly connected at its one end to the spindle (,) and is rotationally fixedly connected at its other end to the latching flange (,). A further torsion bar (,) is provided, which can be selectively switched in.

Belt winder

The invention relates to an arrangement for the rolling up of a belt band (,) comprising a reel (,) which has at its jacket surface (,) an axial cut-out (,) extending parallel to the reel axis, comprising a belt band (,) secured to the reel (,) and comprising a reinforcement element (,) which is arranged at the reel (,) and which bridges the axial cut-out (,).

Arrangement for the rolling up of a belt band

An arrangement for the attachment of a belt to a reel of a safety belt reeling mechanism has a shaft (10') and a reel (12') arranged coaxial to the shaft with a belt (14') attached to the reel (12') forming a closed loop (16') at its end. A securing pin (18') extending transverse to the direction of the belt is provided in the loop and is not formed by the shaft (10').

Safety belt attachment arrangement

The invention relates to a safety belt arrangement in vehicles having a belt tensioner comprising: a holder which is to be secured to the vehicle chassis, with a belt winding reel with a safety belt wound thereon being rotatably mounted on the holder; a belt retraction spring arrangement by means of which the safety belt is continuously lightly pretensioned in the draw-in direction so that it only loosely lies against the vehicle occupant secured by it; and an auxiliary drive which is separated drivewise by a clutch from the belt winding reel but is activated abruptly with an accident-dependent acceleration and is rotationally fixedly coupled to the belt winding reel via the then engaged clutch. The auxiliary drive has two band running chambers separated by sealing walls and two draw bands which are each arranged in one band running chamber, with the draw bands being secured at one end to a housing and at the other end to a drive reel and being acted on by the pressure source in the event of an accident-dependent acceleration of the vehicle in order to drive the drive reel which is fixedly connected to the belt winding reel in the belt draw-in direction. In accordance with the invention, the clutch is accommodated in a hollow coupling cavity provided in the drive reel.

Safety belt arrangement in motor vehicles having a belt tensioner

A belt tensioner for safety belt arrangements in motor vehicles has a holder (11) on which are provided a belt winding reel (12) with a safety belt (13) coiled thereon, a blocking arrangement and an additional drive (15) connected via clutch (20) to the belt winding reel (12). The additional drive (15) contains a pressure source (16) which abruptly builds up a high pressure in a pressure chamber on being triggered and also contains a torque generating device (18) acted on by the pressure in the pressure chamber (17) and a drive shaft (19) connected to the latter. The drive shaft (19) is rotationally fixedly connectable to the belt winding reel (12) via the clutch (20). The torque generating device (18) includes a flexible draw band (21) which is secured at one end at a first mounting point (25) to the periphery of the drive shaft (19) or to the drive reel (22) concentrically mounted thereon and is partially wound onto the drive shaft (19), or onto the drive reel (22) and is secured at the other end, at a second mounting point (26) to the peripheral wall (30) of a band running chamber (23) within a housing (24). Pressure applied to the draw band causes belt tensioning movement of the drive shaft (19) or drive reel (22).
