<p>A passenger vehicle door latch assembly 10 (Figure 2) includes a cam e.g. 90a rotating in common with a latching claw 30 which is retained by a pawl 34 at first safety and fully closed positions of an associated door, the shaping of the cam controlling operation of locking mechanism of the assembly. Lobes, e.g. 92a,92b on the cam co-act to shift a release lever 64 of the mechanism back to an active position at which it will free the pawl by operation of a door handle for opening of the door even if it has previously been set to a disabled condition at which the door would otherwise be locked so as to prevent inadvertent slam locking of the door. Different cams 90a,90b 90c or 90d may be substituted in an otherwise common assembly to provide a selection of logic sequences of self-cancelling or prevention of locking operations. <IMAGE></p> |
