ELECTRIC DOOR LOCK ACTUATOR

摘要

Electric Door Lock Actuator 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 loss motion coupling together with a pair of springs mounted to engage a shoulder extending from a rack are disclosed to achieve the above function.
