ABSTRACT:
This vehicle door latch assembly incorporates a blocker bar which has a follower operatively mounted within a conical recess of an upstanding block so that when subjected to an unbalancing force of predetermined magnitude, the block will be tilted and the bar moved to a block position in which a transfer lever of the latch assembly is inhibited from turning. An associated intermittent lever is resultantly immobilized so that a connected detent lever cannot be moved from a holding position with respect to a spring biased locking bolt. With the locking bolt so held, it cannot be moved from a latching position with respect to a striker to thereby prevent door opening. When door opening is subsequently desired, an unblocking lever system can be actuated to cam the blocker bar to a release position allowing the transfer lever to be turned by a pull handle and a connected release rod to effect the spring biased movement of the locking bolt to an unlatching position with respect to the striker. A dual lever holding system on the release lever rod and on lock control rod is operable to hold the lock control rod in an unblocking position until the pull handle is released from a door opening position so that the lock control rod is returned to its unlocked position.
