Abstract
A reverse to park mechanism of the type in which a crank arm is eccentrically pivoted relative to a reversable drive shaft axis. The crank arm is held in a first position by a drive lug on one side of the crank arm that prevents it from pivoting in one direction, and a latching lever pivoted to the crank arm that engages a latching pin to prevent it from pivoting in the other direction. The orientation of a keeper surface of the latching lever relative to the cylindrical surface of the latching pin that it contacts is designed to provide a very strong resistance to slip off, while allowing a reversal activated torque means to easily move the keeper surface off of the latching pin to release the crank arm.
