ABSTRACT:
A power door latch that eliminates the need to slam a door and that also allows the required two stage lock to engage. The OEM striker once engaged is driven toward the door frame in a linear motion, by a reversible electric motor that drives an acme screw within the drive housing. Adjustable limit switches detect full closure and full open to activate and deactivate the motor. A mechanical delay is incorporated within the drive housing to allow the engagement of the two stage lock mechanism. The power door latch can be used with any OEM striker in most vehicles. Additionally, the power door latch can be manually engaged in the event of a power failure.
