Abstract: A passive seat belt system having a torso belt that in passenger restraining position extends over upper torso of the seat occupant from a fixed roof rail attachment to a retractor mechanism anchored at the inboard side of occupant seating position. A trolley is movable along a track that in part parallels the vehicle roof rail and in part the windshield pillar at one side of the vehicle body. The trolley carries a "D" ring that engages the torso belt intermediate its ends. The trolley is movable along the track by a cable mechanism responsive to movement in door opening direction. As the trolley moves along the portion of the track paralleling the roof rail from the track end adjacent the roof rail attached end of the torso belt, the "D" ring automatically raises the torso belt forwardly and upwardly from restraining position. A hanger catch extends below the track prior to the point at which the track curves downwardly alongside of the windshield piller.
