    Abstract: A latch for a vehicle body closure, the latch including a latch bolt, a detent lever, means frictionally resisting movement of the detent lever and a transfer lever operable to overcome the friction and move the detent lever into and out of a detenting position against the latch bolt. A control pin on the latch bolt engages the transfer lever during movement of the latch bolt from an unlatched to a latched position to actuate the transfer lever and initiate simultaneous movement of the detent lever to the detenting position, the aforementioned friction functioning to maintain the detent lever in the detenting position.

    Abstract: A seat belt retractor includes a U-shaped support having generally vertically disposed closed end slots in the side walls thereof. A reel having ratchet toothed end plates and a shaft mounts a seat belt. The ends of the shaft are received within the slots and torsion springs bias the shaft ends into engagement with the lower ends of the slots. The reel is spring biased in a belt retracting direction. A pawl is movable mounted on the side walls of the frame and normally located against movement by a columnar spring. Cooperating cam surfaces on the pawl and side walls move the pawl laterally of and into engagement with the ratchet plates of the reel when the pawl moves laterally of the side walls or longitudinally of the reel. When belt acceleration or movement of the belt in an extending direction exceeds a predetermined rate, the reel moves bodily upwardly with respect to the frame as the shaft ends move within the slots, and the ratchet plates of the reel engage cooperating teeth on the side walls of the frame to block further rotation of the reel in a belt extending direction. When the pawl is subjected to an acceleration pulse of predetermined amplitude and time longitudinally thereof and generally normal to the direction of bodily movement of the reel, the pawl moves laterally of the side walls and into engagement with the ratchet plates of the reel to provide a fulcrum for movement of the reel bodily upwardly so that the ratchet plates of the reel again engage the cooperating teeth on the side walls of the frame. When the pulse is laterally of the pawl, it also moves into engagement with the ratchet plates to provide the same fulcrum.

    Abstract: A vehicle body door lock detent lever is pivotally and slidably mounted on a stud carried by the lock frame. A combined compression and torsion spring normally biases the detent into detented engagement with the bolt and also holds serrations on the detent out of engagement with mating serrations on the stud. This spring is opposed by a Belleville washer and is normally stronger than the washer. If for any reason the washer becomes stronger than the spring, the detent shifts axially of the stud to engage the serrations.
