ABSTRACT:

A controllable actuating means having cams and stops controls the position of the spring coil and the diameter of the spring coil to either grip or release the grip on the turntable member in response to manipulation of the seat belt by the passenger. A remote control actuator also may change the spring coil diameter of release the tension relieving mechanism allowing automatic rewind of the belt with the opening of the vehicle door.
