    Abstract: A winding prevention mechanism for a vehicle occupant restraint belt retractor of the inertia locking type that selectively holds the associated restraint belt unwound for use against the winding bias of the retractor belt reel. The mechanism is actuated to hold the belt unwound when the belt is unwound slightly further than the length required to snugly belt an occupant, allowed to wind back to a snug condition, and then unwound a slight amount less than a limited extent. If the belt is unwound more than the limited extent, the mechanism permits belt winding reel rotation that stores the belt within the retractor. A leaf spring type pawl is mounted on the retractor housing and normally biased into engagement with a ratchet wheel carried by the retractor belt reel so as to provide the actuated mechanism condition holding the belt unwound. A blocking disk is frictionally clutched to the belt reel so as to move between a blocking position preventing this engagement and a non-blocking position where the engagement is allowed. A control disk also frictionally clutched to the belt reel has a control portion that moves the pawl out of engagement with the ratchet wheel so as to allow the blocking disk to move to the blocking position in a manner that provides the sequenced operation of the retractor.

    Abstract: AN AUTOMATIC LOCKING RESTRAINT BELT LINEAR RETRACTOR INCLUDES A GENERALLY FORK-LIKE CARRIER THAT HAS A BASE WITH SPACED PAWL LEGS EXTENDING THEREFROM AND SPRING BIASED TOWARD THE BASE WALL OF THE RETRACTOR HOUSING. MOVEMENT OF THE FREE END OF A RESTRAINT BELT OUTWARDLY OF THE HOUSING MOVES THE BELT FROM A FULLY STOWED POSITION WITHIN THE HOUSING AND CONCOMITANT THEREWITH MOVES THE CARRIER FROM A FULLY RETRACTED POSITION TOWARD A SUCCESSIVE SERIES OF EXTENDED POSITIONS. DURING MOVEMENT OF THE CARRIER TO THE FIRST EXTENDED POSITION OF THE SERIES FROM AN INTERMEDIATE POSITION SLIGHTLY RETRACTED THEREFROM, THE SPRING BIAS CAUSES THE PAWL LEGS TO ENGAGE AND MOVE RESPECTIVE BLOCKING MEMBERS FROM UNBLOCKED POSITIONS TO BLOCKED POSITIONS N WHICH THE BLOCKING MEMBERS BLOCK ENGAGEMENT OF THE PAWL LEGS AND LINEAR RATCHET WALLS OF A CHANNEL-SHAPED LINEAR RATCHET MEMBER MOUNTED ON THE BASE WALL. WITH THE BLOCKING MEMBERS IN BLOCKED POSITIONS, THE CARRIER IS THUS FREE TO MOVE TO ANY EXTENDED POSITION OF THE SERIES AD UPON THE INITIAL RETRACTING MOVEMENT THEREFROM, THE PAWL LEGS ENGAGE AND MOVE THE BLOCKING MEMBERS TO UNBLOCKED POSITIONS TO ALLOW ENGAGEMENT OF THE PAWL LEGS AND THE RATCHET WALLS WHEREUPON A SUBSEQUENT OUTWARDLY APPLIED BELT FORCE PIVOTS THE BASE OF THE CARRIER INTO ENGAGEMENT WITH THE COVER WALL OF THE HOUSING TO HOLD THE CARRIER FROM FURTHER EXTENDING MOVEMENT AND THE FREE END OF THE BELT FROM CORRESPONDING MOVEMENT OUTWARDLY OF THE HOUSING.

    Abstract: A vehicle occupant restraint belt retractor in which a winding prevention mechanism responsive to belt reel rotation prevents belt winding reel rotation under the spring bias of the reel when the belt is being buckled in use position after unwinding from its fully stored condition on the reel. The mechanism includes a pawl for engaging the reel to prevent the belt winding movement thereof and a sensing member that moves under a leaf spring bias in response to the diameter of stored belt on the reel so as to control the pawl movement as a function of the length of unwound belt. The pawl is mounted on a shaft of the retractor housing in a pin and slot fashion for pivotal and limited bodily shifting movement with respect thereto and the sensing member is pivotally mounted on the same shaft. A pin and leaf spring on the sensing member are engageable with and control the pawl movement in a manner that allows belt winding reel rotation after the buckled belt is pulled from the retractor a slight amount. Secondary locking surfaces on one of the end plates of the retractor belt reel are arranged in opposed relationship to the primary locking surfaces that are selectively engaged by the retractor locking member to prevent belt unwinding reel rotation, and these secondary surfaces are where the pawl engages the reel to prevent the belt winding reel rotation.
