Abstract

This is a seat belt system for a motor vehicle which has a belt retractor behind the inboard rear corner of the seat, a belt guide next to the inboard side of the head rest, a slip ring on a slide in an upwardly and forwardly inclined guideway in the vehicle door next to that seat, and an anchor next to the inboard side of the seat in front of the belt retractor. The seat belt extends up from the retractor behind the back rest of the seat, slidable through the belt guide at the inboard side of the head rest, downward and laterally outward diagonally across the front of the back rest from the guide to the slide on the door, and slidably through the slip ring on that slide back across the seat to the anchor.
