Abstract
A dual drive window regulator mechanism is disclosed for use in an automobile door assembly for raising and lowering the window glass. The system provides two attachment points to the glass for raising and lowering the glass. This can be accomplished by using various lift mechanisms including a translating rack or a dual cable and drum mechanism. By driving the window at two points as opposed to one point in typical regulator mechanisms, more accurate control of the movement and location of the window glass in the door assembly is achievable.
