Lead screw window regulator

A window-regulating assembly for selectively moving a window of a vehicle door between an open position and a closed position, said window-regulating assembly comprising:

• a rail fixedly adapted to be secured to the vehicle door and extending through a radius of curvature of the vehicle door;
• a lift plate slidably engaged with said rail and adapted to have the window fixedly secured thereto such that said lift plate moves the window between the open and closed positions;
• a lead screw secured to said rail, said lift plate traveling along said lead screw to move the window between the open and closed positions;
• a drive motor secured to said lift plate, said drive motor receiving electrical energy and converting the electrical energy into a selectively bidirectional rotational force to drive said lift plate over said lead screw, said drive motor defining a center of mass;
• and
• a pivot mount extending between said drive motor and said lift plate allowing said drive motor to move through said radius of curvature as said lift plate slides along said rail.
