ABSTRACT:
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 includes a housing having slots mounting a pin for movement toward and away from the buckle. The belt passes around the pin. A buckle is selectively engageable with the junction ring to establish the lap belt and shoulder belt in occupant restraining positions across the seat. The shoulder belt is wound by a seat belt retractor having a tension reliever permitting introduction of slack into the shoulder belt. A spring urges the pin in the direction toward the buckle so that the belt is carried into frictional engagement with a friction member to provide a one-way friction detent which prevents transference of the shoulder belt slack into the lap belt so that the lap belt remains taut about the occupant. The spring acting on the pin yields upon the onset of an occupant restraint load to permit movement of the pin away from the buckle and the friction member so that the continuous-loop belt is permitted to pass through the junction ring to adjust the relative restraint lengths of the lap and shoulder belt portions. The frictional engagement of the friction member with the belt is terminated upon disengagement of the junction ring from the buckle so that the belt may pass freely therethrough.
