<p>A remote actuator (10) for an automobile power door lock application has a housing (12), a first gear reduction stage in a first tier (A) in the housing, a second gear reduction stage in a second tier (B1 in the housing, a reversible pancake-type electric motor (56) in the second tier (B) in the housing operative to drive a second gear means (40,46) through a first gear means (30,32) with two stages of gear reduction between respective ones of a pair of parked positions, a linear actuator (108) in the housing (12) in a third tier (C) thereof movable in extending and retracting directions between positively defined limits, and a rotary detent clutch (88) between the second gear means (40,46) and the linear actuator (108) operative to move the latter in the one of the extending and retracting directions corresponding to the direction of rotation of the second gear means (40,46) and to release the linear actuator (108) at either of the limits thereby to permit overdrive of the second gear means (40,46) to the corresponding one of the parked positions.</p> |
