Abstract: A passive vehicle occupant restraint belt system comprises a belt leading from an inboard location adjacent the lower rear portion of the seat to an outboard location adjacent the rear edge of the vehicle door. An elongated guide rail affixed on the inboard side of the seat carries a belt transfer guide having a guide ring through which the belt passes intermediate the inboard and outboard ends. The guide rail extends lengthwise along the seat and slopes upwardly from back to front. The guide ring is located at substantial distance above the guide rail, and the slope of the guide rail is such that the guide ring holds an inboard portion of the belt at substantially the level of or some distance above the level of the front of the seat when the belt transfer guide is in the forward position on the guide rail. The belt transfer guide is driven back and forth along the guide rail, preferably in response to opening and closing motions of the door.

Abstract: A vehicle occupant restraint system for restraining an occupant of a seat located adjacent a door that is hinged along the front edge comprises a shoulder belt having one end secured to an anchor affixed to the upper rear portion of the door, a portion that extends down and in across the seat and an inboard portion that is wound on to an emergency locking retractor. An elongated guide rail extending along the edge of the roof generally coextensively with the upper edge of the door receives a slider for sliding movement therealong. A belt guide ring is movably attached to the slider and receives the intermediate portion of the belt for movement therethrough. The system may also comprise a lap belt having its inboard end secured to the intermediate portion of the shoulder belt and its outboard end wound on to an emergency locking retractor affixed adjacent the lower rear corner of the door.
