ABSTRACT:
A passive lap and shoulder belt system for a motor vehicle includes a shoulder belt having an outboard end attached either to the roof rail or the door window frame and an inboard end suitably mounted inboard the occupant. The lap belt has an outboard end mounted on the door and an inboard end suitably mounted inboard the occupant. The shoulder belt and lap belt each have a retractor at one of their belt ends. A track extends longitudinally forward from the shoulder belt retractor and movably mounts a shoulder belt carriage which slidably engages the shoulder belt. A fixed length lift cable extends slidably through the shoulder belt carriage and has an upper end mounted adjacent the rear end of the track and a lower end connected to the lap belt. A suitable drive device moves the shoulder belt carriage forwardly along the track when the door is opened to thereby dispose the shoulder belt forwardly of the occupant and move the lift cable upwardly and forwardly to lift the lap belt upwardly and forwardly away from the seated occupant to facilitate occupant ingress and egress.
