Abstract
A power actuator used in combination with a motor-vehicle door latch movable between a locked and unlocked position has a housing, a reversible electric motor in the housing having a rotatable output shaft defining an axis, and an input gear on the shaft. A threaded output spindle spaced from the shaft in the housing carries an output gear out of mesh and out of engagement with the input gear. A nut is threaded on the spindle. An actuating element couples the nut with the latch to switch it between its positions. A support pivotal in the housing about the axis carries a pair of coupling gears in mesh with and flanking the input gear. The support is rockable about the axis from a central position in which neither of the coupling gears meshes with the output gear into a pair of end positions in each of which a respective one of the coupling gears meshes with the output gear and couples same to the input gear. The support is biased into the central position with a relatively small force such that on rotation of the input gear in either direction the biasing force is overcome and the support is rocked in the same direction into the respective end position.
