ABSTRACT:
A passive occupant restraint belt system for a vehicle which includes a restraining belt and apparatus for moving the belt from an occupant restraint to an occupant releasing position in response to opening of a door of a vehicle. A belt transfer device engages the seat or shoulder belt for moving the belt between the restraining to releasing positions and is actuated by a motion transmission mechanism which transmits and amplifies opening motions of the door to the belt transfer device. The transmission includes a motion amplifier mounted on either the vehicle body or door, and a linkage having one end attached to the other of the body and door and its other end coupled to an input component of the motion amplifier. The linkage is coupled to the other of the vehicle body or door during normal door operation when the door is between closed and partway open to transmit door opening movement to the amplifier but released when the door is between partway open and fully open. The linkage also releases in emergency situations, when the amplifier or belt transfer mechanism is damaged and thereby inoperative, so that the door may open notwithstanding the inability of the motion amplifier to operate.
