ABSTRACT:
A vehicle door latch mechanism (10) having an improved double lock assembly (34). The present double lock assembly (34) is disposed between the latch handle assembly (30) and the latching assembly (26). In the un-double locked configuration, the double lock (34) allows motion transfer from the latch handle assembly (30) to the latching assembly (26) by extending the secondary intermittent member (36). In the double locked configuration, the double lock (34) retracts the secondary intermittent member (36) to prevent motion transfer between the latch handle assembly (30) and the latching assembly (26), preventing any unlatching of the door (12) even if the lock assembly (32) is in the unlocked configuration.
