Abstract:
A vehicle door latch having a forkbolt that moves between a latched position and an unlatched position and a detent for holding the forkbolt in the latched position, characterized by a power operated release mechanism for moving the detent to a position releasing the forkbolt, the power operated release mechanism comprising:a power unlatching lever moveable from a rest position to an unlatch position the power unlatching lever engaging the detent or a part connected to the detent and moving the detent to the position releasing the forkbolt when the power unlatching lever moves from the rest position to the unlatch position, and a motor driven actuator that is operatively connected to the power unlatching lever for moving the power unlatching lever from the rest position to the unlatch position, the motor driven actuator including a bell crank lever that is rotated about a first pivot and a bell crank link that is pivotally connected to the bell crank lever at one end by a second pivot and that is pivotally connected to the power unlatching lever at the other end by a third pivot, the first pivot, the second pivot and the third pivot being aligned substantially linearly when the power unlatching lever is in the rest position to hold the power unlatching lever in the rest position.
