Abstract: A seat belt retractor adapted for mounting on a vehicle door includes an inertia sensing pendulum for moving the lock bar into engagement with a belt reel to lock the reel against belt unwinding rotation. A feeler device, such as a plunger, is mounted on the door for sensing initial movement of the door away from the closed position. A flexible element, such as a chain, is connected to the pendulum and the feeler device. The flexible element has a normal slackened link when the door is closed so that the pendulum is free for movement to move the lock bar to the reel engaging position. Upon initial door opening movement, the plunger extends and tensions the flexible element so that the flexible element restrains the pendulum against movement from the normal position by an inertia stimulus induced by door opening movement.

Abstract: A belt clamping mechanism for a seat belt retractor having a belt reel rotatably journaled on a frame and a locking means for locking the reel against unwinding rotation. The retractor frame is mounted on the vehicle body for limited movement in the direction of belt pull. A yieldable device such as a frangible member acts between the frame and the vehicle body to establish the frame at a normal position in which a belt clamping member carried by the retractor frame is spaced from a clamping abutment mounted on the vehicle body. When the reel is locked and an occupant restraint load is imposed on the belt, the yieldable device permits movement of the reel and the frame in the direction of belt pull so that the belt is clamped between the clamping member carried by the frame and the clamping abutment mounted on the vehicle body to fix the belt length against spooling down on the reel.

Abstract: A linear belt storage retractor includes a locking mechanism attached to the end of the belt and travelling vertically inside a vertical tubular housing mounted on the vehicle body. The weight of the locking mechanism retracts the belt into the tubular housing. The locking mechanism includes a ramp member attached to the belt and having a ramp surface facing the inner wall of the tubular housing. A wedge member is seated upon the ramp surface and moves radially relative the inner wall upon axial movement relative the ramp member. A platform engages the wedge member and is spring biased to support the wedge member at a normal position away from the inner wall.

Abstract: A seat belt retractor and locking mechanism includes a cable attached to the restraint belt and attached to a spring biased reel. A housing encircles the cable and encloses first and second collet members having aligned inner walls with mating recesses defining a cable passage therethrough and opposed-facing angularly-inclined outer walls. First and second rollers are interposed respectively between the housing and the inclined outer walls of the collet members. A pair of spring clips acting between the collet members and an adjustable support plate for the rollers cooperate to establish a normal spaced apart position of the collet members in which the cable passes freely through the cable passage during belt extension and retraction induced by winding and unwinding of the cable from the reel.

Abstract: A buckle assembly for a continuous loop lap and shoulder restraint belt system includes a latch plate assembly carried by the belt and a buckle mounted on the body. The latch plate includes a housing having a cinching member pivotally mounted thereon. The continuous loop belt passes around the cinching member. The buckle has a lip member on the buckle housing which projects into proximity with the restraint belt generally along one side of the cinching member to provide an abutment surface against which the cinching member may clamp the restraint belt. When a load is imposed on the lap belt portion of the continuous loop belt, the cinching member is rotated in the direction to clamp the belt against the abutment surface of the buckle housing to prevent sliding movement of the continuous loop belt in the direction to increase the length of the lap belt.

Abstract: A seat belt retractor has a belt reel rotatably mounted on a support member which is mounted on the housing by a pivot axis spaced from the reel shaft. A lockbar is pivotally mounted on the housing for movement between a locking position engaging a ratchet plate attached to the reel and an unlocked position disengaged from the ratchet plate to permit belt unwinding. A latch acts between the reel and the support member to normally latch the reel support member with the housing at a position establishing the reel ratchet plate in proximity with the lockbar for the selective locking engagement by the lockbar. The latch may be manually disengaged to permit the belt load acting on the reel to pivot the support member about the pivot axis and thereby carry the reel and ratchet plate away from locking engagement with the lockbar to permit belt unwinding irrespective of the lockbar being located at the locking position.

Abstract: A seat belt retractor for use in a passive seat belt system having one of the belt ends attached to the vehicle door. A belt reel is rotatably mounted on the retractor housing for belt winding and unwinding rotation. A toothed ratchet plate is carried by the reel. A lockbar is pivotally mounted on a support link which is in turn pivotally mounted on the retractor housing. A stop provided on the housing limits movement of the support link in the direction toward the toothed ratchet plate to establish the support link at a normal position wherein the pivot axis of the lockbar is situated over center with respect to the locking face of the lockbar and the pivot axis of the support link. Accordingly, whenever the inertia sensing pendulum moves the lockbar into locking engagement with the ratchet plate, the stop supports the support link and the lockbar against movement by the belt load so that the reel is locked against unwinding rotation.

Abstract: A seat belt securing device includes a C-shaped hook member having upper and lower legs spaced apart to define a belt receiving slot having a forwardly facing open end. The lower leg is pivotally mounted on a mounting bracket attached to the vehicle body and positioning the hook member adjacent the hip of the seated occupant. The upper leg is engaged by the belt upon entry of the belt into the slot and is arranged relative the pivot so that belt force applied against the hook member by a retractor associated with the belt and by restraint of the occupant maintain the hook member in a downwardly directed belt capturing position. A gate member is pivotally mounted on the mounting bracket and is spring biased to a normal position where its one end engages the upper leg to close the open end of the slot and a latch portion at its other end engages a notch in the lower leg to latch the hook member against rearward belt releasing motion.

An abutment lip extends downwardly from the upper leg adjacent the open end to partially close the open end of the slot to assist retention of the belt against inadvertent disengagement. A gate member is pivotally mounted on the mounting bracket and is spring biased against the lip to normally close the open end of the slot.
