ABSTRACT:
A shaft on which a restraint belt is wound is rotatably mounted in the side walls of a U-shaped frame. A plastic belt guide is connected by side arm belt edge protectors to tubular flanges that form bushings for the shaft. A driving hub mounted on the shaft drives a locking hub through a clutch formed of ball bearings mounted in recesses in the faces of the hubs. Belt payout rotation of the shaft at a predetermined acceleration will cause the locking hub to rotationally lag. This causes the locking hub to move axially and further causes locking teeth on the locking hub to engage holes in the sidewall of the frame. This prevents further rotation until the belt extension load on the belt is removed. A synchronization spring arrests rotation of the locking hub as it moves axially into locking position.
