Electrically controlled actuator for a vehicle door latch assembly
First Claim
1. An electronically controlled actuator for controlling a door latch assembly between an unlocked condition, a first locked condition and a second locked condition, said actuator comprising;
- a cover having at least one projecting abutment;
a cam rotatably mounted to said cover and including a camming surface defining at least one stop for selective engagement with said abutment;
a rocker movably mounted to said cover for selectively engaging said camming surface of said cam;
a first controller for rotating said cam between a first position wherein said stop engages said abutment and said rocker engages said camming surface for defining the unlatched condition of the door lock;
a second position wherein said rocker engages said stop to prevent further rotation of said cam and define the first locked condition; and
a third position wherein said stop engages said abutment and said rocker is released from said camming surface to define the second locked condition; and
a second controller for rotating said rocker to release said rocker from said camming surface during rotation of said cam from said second position to said third position.

Abstract
A vehicle door latch assembly is moveable between an unlocked condition, a locked condition and a double locked condition. The door latch assembly has a support housing with a cover having a projecting block. A cam is rotatably mounted to the cover and includes an integral notch defining a pair of stops for selective engagement with the block. A rocker is movably mounted to the cover for selectively engaging at least one of the stops of the notch within the cam. A first controller rotates the cam into selective engagement with the block and the rocker for defining the unlocked condition and the locked condition, respectively, of the door lock. A second controller rotates the rocker to release the rocker from one of the stops of the notch to allow further rotation of the cam from the locked condition to the double locked condition.
