ABSTRACT LOCKING JUNCTION RING FOR CONTINUOUS-LOOP PASSIVE SEAT BELT SYSTEM A load locking junction device is provided to couple a continuous-loop belt (20) having ends mounted on the vehicle door with an anchor belt (32) retractably mounted at the inboard side of the occupant seating position. The junction ring (34) includes a stamped metal frame (40) having a central elongated aperture defining spaced apart first and second elongated load bearing walls (46), (48). The continuous-loop belt (20) is slidable over the first wall (46) to divide the continuous-loop belt into a lap belt portion (38) and a shoulder belt portion (36). The anchor belt (32) extends through the aperture and has a pin (50) engaged in the end thereof to enlarge the anchor belt end por- tion for simultaneous engagement against the second wall (48) the continuous-loop belt so that the belts are cou- pled together and maintained in engagement with the load bearing walls against migration towards the ends of the elongated aperture. A spring (56) acts between the frame and the pin to normally hold the anchor belt (32) in spaced relation from the continuous-loop belt (20) and thereby permit free adjusting movement of the con- tinuous-loop belt through the junction ring. The im- position of oppositely directed occupant restraining loads on the continuous-loop belt and the anchor belt during emergency induced vehicle deceleration causes the enlarged anchor belt end portion to forcefully clamp the continuous-loop belt against the first load bearing wall (46) whereby the restraining lengths of the lap belt and shoulder belt portions are fixed relative one another. A disconnect buckle (29) provided at one end of the continuous-loop belt may be disconnected to terminate the occupant restraining load so that the clamping effort is terminated and the continuous-loop belt may pass freely through the juncture ring to permit opening movement of the door and occupant egress.
