ABSTRACT:
A belt retractor shaft-rotating pretensioner for a vehicle seat belt comprises a cable, a power source coupled to a pulling portion of the cable for pulling the cable, and a mechanism for coupling a pulled portion of the cable to a reel shaft of the belt retractor when the cable is pulled to transmit rotation to the reel shaft. A brake unit ensures that the coupling mechanism remains engaged with the reel shaft when the cable is pulled. The brake unit includes a friction device on one end of a lever that frictionally engages the pulling portion of the cable and generates a braking input force when the cable is pulled and a brake shoe on the other end of the lever for transmitting the braking input force to the pulled portion of the cable.
