Abstract

A motor driven window regulator combined with a door lock for a motor vehicle. A reversible motor is used to drive a sector gear. The sector gear in turn rotates a gear to pivot a lever to raise and lower the window. An engaging clutch pivoted to the free end of the lever is used to couple and decouple the mechanism to the window.

  1. 1. A combination power window and power door locking device for use in an automotive vehicle door comprising, in combination:a reversible electric motor;means for mounting said motor internally of said door;first means for coupling said motor to a movable window pane holder within said door to move said holder between first and second end positions;second means for coupling said motor to a movable extension of a door locking mechanism within said door which is activated to lock and unlock said door;means for selectively applying external power to said motor;means cooperating with said first and second means and responsive to the position of said holder for engaging and activating said door locking mechanism when said holder is in one of its end positions;wherein said motor is rotatably mounted in said door and resiliently urged toward an angular stop position until said holder is in said one of its end positions whereupon continued application of said external power to said motor rotates said motor away from said stop position to activate said door locking mechanism;wherein said second means includes:an input element connected to said motor, an output element connected to said extension of said door locking mechanism and a disengaging clutch connecting said input element to said output element; and,wherein said door locking mechanism includes an actuating member connected to said output element for manually locking and unlocking said door when a predetermined force is applied to said actuating member; andwherein said disengaging clutch disconnects said output element from said input element when the force transmitted through said disengaging exceeds said predetermined force.
