Abstract:
In one aspect, the invention is directed to a closure latch for a vehicle door. The closure latch includes an emergency lock actuator to permit a person to lock the door in the event that the power lock actuator is unusable. The latch also includes an ‘impatient passenger’ feature, which permits the doors to be unlocked using the remote keyless-entry feature on the key fob even in a situation where an ‘impatient passenger’ had prematurely lifted the door handle of the vehicle. In some prior art latches, such an action by an ‘impatient passenger’ would prevent the drive motor on the latch from unlocking the latch, thereby necessitating the owner to press the unlock button on the key fob a second time. There is some overlap in the components that used for the ‘impatient passenger’ feature and the components used for the emergency lock actuator, thereby reducing cost and complexity of the latch.
