ABSTRACT:
A passive occupant restraint belt system for a vehicle which includes a restraining belt and apparatus for moving the belt between occupant-restraining and occupant-releasing positions in response to partial opening of a door of the vehicle. A belt transfer device engages the seat or shoulder belt for moving the belt from the retraining to the releasing position and is actuated by a motion transmission mechanism which transmits and amplifies door opening motions to the belt transfer device. The transmission includes a motion amplifier mounted on either the vehicle body or door, and a force transmitting input rod having one end coupled to an input component of the motion amplifier. The other end of the rod engages a coupler mounted on the other of the vehicle body or door, the coupling arrangement such that the rod is connected when the door is between closed and partway open to transmit opening and closing motions of the door to the motion amplifier thereby to move the belt transfer device between its releasing and restraining positions. The rod, however, is disconnected from the door or body when the door is between partway open and fully open, such that the door may be fully opened without further actuating the belt transfer mechanism. The coupler for engaging the input rod also includes an emergency releasing feature for permitting the door to open when the belt transfer mechanism or amplifier is inoperative and thereby bound up.
