ABSTRACT:
A passive seat belt system having a belt anchored to a hinged vehicle door at upper and lower anchorage points and a strap extending from an inboard retractor mechanism to a slip ring slidably on the belt. In door closed position, the portions of the belt between the slip ring and the lower anchorage point and the slip ring and the upper anchorage point forming a lap belt segment and a torso belt segment, respectively, for restraining a seat occupant on a vehicle seat. A fixed web stop located on the lap belt is sized to prevent its passage through the slip ring as the door is opened. The effective length of the torso segment becomes fixed upon engagement of the web stop with the slip ring causing the torso segment and retractor strap to be placed under linear tension and the retractor strap and belt segments to be lifted upwardly and forwardly of a seat occupant.
