Abstract: A positive restraint safety system consists of an automatic lap belt and shoulder belt assembly which move simultaneously within two tracks and a rotatable belt position guide, an extendable belt position guide or a trackable belt position guide to restrain or to release a seated occupant in a vehicle. The simultaneous movements of the lap belt, shoulder belt and belt position guide are predetermined by the movements of vehicle wheel, door and engine, and the independent manual switch operation. When the lap belt and shoulder belt simultaneously move from restrained position to released and stand-by position, they move away from the body and above the lap of the seated occupant to a most desired position, therefore all belts are unobtsructing for a driver or passenger to exit from or to enter into a vehicle seat.
