ABSTRACT:
A passive vehicle occupant restraint belt system includes a restraining belt and apparatus for moving the belt between an occupant-restraining and an occupant-releasing position in response to the closing and opening of the door of the vehicle. A belt transfer device engages the lap or shoulder belt, moves the belt between the restraining and the releasing positions and is actuated by a motion transmission mechanism which transmits and amplifies opening and closing 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 the other end coupled to an input component of the motion amplifier so that opening and closing movement of the door is transmitted through the linkage to the motion amplifier. The linkage incorporates an interrupting mechanism which is actuated by a detector sensing the presence or absence of an occupant in a vehicle seat to actuate the interrupting mechanism when the seat is empty. With the seat empty and the interrupting mechanism actuated, the belt will not be moved between its releasing and restraining positions when the door is closed or opened.
