摘要： 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. A pendulum sensitive to a predetermined magnitude of vehicle deceleration is effective to initiate axial movement of the collet members so that the rollers coact with the inclined outer walls to contract the collet members into gripping engagement with the cable. The forward momentum of the occupant imparts a load on the restraint belt and cable so that the coaction between the rollers and the inclined outer walls cause the cable to be progressively gripped to thereby lock the effective length of the restraint belt.

摘要： 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. When a load is imposed on the shoulder belt portion of the continuous loop belt, the cinching member is pivoted in the opposite direction to unclamp the continuous loop belt and permit sliding movement of the belt in the direction to shorten the lap belt portion and lengthen the shoulder belt portion. When the latch plate is disengaged from the buckle the belt may pass freely in either direction around the cinching member so that the latch plate is free falling to a desired position along the belt.

摘要： 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. Upon occurrence of ramp member acceleration with the belt in the belt extending direction, the resting inertia of the wedge member and platform overcomes the spring so that movement of the wedge member lags behind the ramp member and the ramp member forces the wedge member radially outward to initiate self actuating frictional locking engagement of the wedge member with the inner walls to lock the ramp member against belt extending movement. A pendulum acts upon the platform to move the wedge member axially relative the ramp member in response to a vehicle deceleration so that the wedge member moves radially to engage the inner wall and thereby initiate self actuating frictional locking engagement to lock the belt against belt extending movement.

摘要： 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. A manually operated handle is connected to the support link and permits the occupant to forcibly move the support link in the direction away from the stop and the ratchet plate so that the pivot axis of the lockbar is moved over center with respect to the support link pivot axis and the face of the lockbar engaging the ratchet plate. Thus, the lockbar is disengaged from locking engagement with the ratchet plate so that the belt may be unwound to terminate restraint of the occupant and permit opening movement of the door.

摘要： 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.

摘要： 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. The spring yields to permit movement of the gate member to a slot opening position when engaged by the belt during engagement of the belt over the upper leg and insertion into the slot. A release lever has a generally planar body portion pivotally mounted on the mounting bracket and a laterally extending occupant accessible push button portion adapted to overlie the upper leg in spaced relation therefrom to permit limited pivotal movement of the release lever relative the hook member. The release lever also has a cam surface for pivoting the gate member out of engagement with the notch of the lower leg during the limited pivotal movement of the release lever. A further occupant depression of the push button portion causes engagement of the laterally extending push button portion with the upper leg to effect rearward pivoting movement of the hook member to release the belt therefrom.

摘要： 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 by a resilient yieldable support for positioning the hook member adjacent the hip of the seated occupant. The upper leg has a curved lower face 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 motion. The spring yields to permit movement of the gate member to a slot opening position when engaged by the belt during engagement of the belt over the upper leg and insertion into the slot. During restraint of the occupant the resilient support yields to permit bodily forward and pivoting movement of the hook member and mounting bracket to maintain capture of the belt without imposing a load on the gate member. The belt is released by pivoting the gate member rearwardly to unlatch the hook member and pivoting the hook member rearwardly to an upwardly directed position to release the belt for windup by the retractor.

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. The spring yields to permit movement of the gate member to a slot opening position when engaged by the belt during engagement of the belt over the upper leg and insertion into the slot. During restraint of the occupant the resilient support yields to permit bodily forward and pivoting of the hook member and mounting bracket to maintain capture of the belt without imposing a load on the gate member. The hook member is manually pivoted rearwardly to an upwardly directed position to move the upper leg away from the gate member and release the belt for windup by the retractor. The belt securing device may be used in a continuous loop three-point belt system or in a two-point lap or shouler belt having a loop sewn on the belt end.
