Passive vehicle passenger restraint belt system

A passive vehicle passenger restraint belt system comprising a mechanical motion amplifier mounted in the door of the vehicle;

• an input device connected between the vehicle body adjacent the front hinged end of the door and the motion amplifier to transmit the opening and closing motions of the door relative to the vehicle body to the motion amplifier;
• a shoulder belt guide rail affixed to the vehicle roof generally above the door and extending between a point generally above and behind the adjacent vehicle seat and a point generally above and forward of the seat;
• a shoulder belt transfer ring received in the shoulder belt guide rail for sliding movement between a rearward and a forward position therein;
• a shoulder belt having a portion received by the shoulder belt transfer ring for movement therewith;
• a lap belt guide rail affixed to the vehicle door and extending between a lower position near the lower rear corner of the door and an upper position near the window ledge;
• a lap belt transfer ring received in the lap belt guide rail for sliding movement between a lower position and an upper position therein;
• a lap belt having a portion received by the lap belt transfer ring for movement therewith;
• and a single continuous drive wire coupled adjacent one end to the shoulder belt transfer ring, coupled at an intermediate driven portion to an output of the motion amplifier to be driven thereby and coupled at the other end to the lap belt transfer ring such that upon opening motion of the door the motion amplifier moves the drive wire in a direction to pull the shoulder belt transfer ring forwardly and push the lap belt transfer ring upwardly in the respective guide rails.
