<p>A vehicle door latch assembly including a pivotally mounted latch claw (10) having a mouth (12) operatively co-acting with a striker as the door nears its closed position, a latching pawl (16) self-engaging with the claw to hold it in latched condition retaining the door, and unlatching means selectively operable to disengage the latching pawl for opening the door. The unlatching means comprises a pawl lifter (20) movable from a position of rest to carry the latching pawl out of engagement with the claw, a power output lever (24) movable to engage and displace the pawl lifter from said position of rest, an input crank (30) power actuated between first and second positions, a clutch (23,32) releaseably drive connecting the input crank to the output lever to cause shifting of the latter as the input crank moves to its second position, and an overriding link (36) carrying the clutch into and out of drive connection. The overriding link IS operatively coupled to a manually operable release link of the door to ensure that manual operation of the pawl lifter is not obstructed by failure or malfunction of power actuation of the input crank. <IMAGE></p> |
