1. A junction ring adapted for use in a seat belt system wherein a continuous loop belt is slidable through the junction ring to define shoulder belt and lap belt portions, a buckle is selectively engageable with the junction ring to establish the lap and shoulder belt portions in restraining positions across the seat occupant, and the shoulder belt portion is wound by a seat belt retractor having a tension reliever permitting introduction of slack into the shoulder belt, said junction ring comprising:

  • a frame, a pin having the continuous loop belt passing therearound, means mounting the pin on the housing for movement toward and away from the buckle, spring means urging the pin in the direction toward the buckle, a friction member adapted to frictionally engage with the belt on the opposite side thereof from the pin when the junction ring is engaged with the buckle to provide a one way friction detent which enables the introduction of slack into the shoulder belt portion by the tension reliever of the seat belt retractor and yet prevents transference of the slack into the lap belt portion so that the lap belt portion remains taut about the occupant, said friction engagement of the friction member with the belt being terminated upon disengagement of the junction ring from the buckle so that the belt may pass freely therethrough, said spring means acting on the pin yielding upon the onset of an occupant restraint load to permit movement of the pin in the direction away from the buckle and the friction member so that the continuous loop belt is permitted to pass freely around the pin and through the junction ring to adjust the relative restraint lengths of the lap and shoulder belt portions.
