FRAMELESS WINDOW REGULATOR RAIL WITH OVER-MOLDED FUNCTIONAL EDGE

A window regulator module for a motor vehicle includes a pair of window regulator rails operably coupled to one another via at least one cable wrapped about pulleys on the window regulator rails. Each window regulator rail has a body extending lengthwise between opposite ends. The body has a main body portion and a guide edge along which a lifter travels upwardly and downwardly. The main body portion is plastic and the guide edge is metal. The metal guide edge provides the window regulator module with increased stiffness and increased cross-vehicle stability to a window carried by the lifters.
