Motor vehicle window regulator with low friction guide rails

摘要

A motor vehicle window regulator in which a matrix coating is applied to a metal blank. The matrix coating is comprised of particles of a fluoropolymer (such as polytetrafluoroethylene) carried in an organic polymer binder. The coated metal blank is cold-formed to the shape of a guide rail with a longitudinal track disposed along an edge of the guide rail. A window slider is mounted onto the guide rail to slide along the longitudinal track, so that the fluoropolymer particles lubricate the sliding of the window slider on the longitudinal track.
