An electric door lock actuator and door lock and latch mechanism are disclosed having manual and electric driven locking means. A combination of a lost motion coupling and resilient spring means for driving the motive means to a neutral position are utilized to effectively isolate the electric motor and gearing from the locking means such that the locking means may be operated manually without back-driving the electric motor and intermediate gearing. A specific rack defining a portion of the lost motion coupling together with a pair of springs mounted to engage a shoulder extending from a rack are disclosed to achieve the above function.

An electric door lock actuator including a door latch locking means which comprises: a reciprocally driven rack means including a shouldered section having a defined travel path; a housing having the rack means mounted therewithin; motive means for driving the rack means; spring means mounted within the housing and positioned to be compressed by the shouldered section of the rack means toward the end of the rack means travel path, said spring means acting to displace the rack means from an end of the travel path when the motive means is not energized; a connecting member extending between the rack means and the door latch locking means; and said connecting member and rack means collectively forming a lost motion coupling, said coupling allowing the rack means to displace the connecting member to drive the door latch locking means and allowing the spring means to displace the rack means without displacing the connecting member or latch locking means.
