Abstract
This invention relates to a window regulator comprising a guide rail having a slideway of L-section and a window-bearing slider in which is made a notch adapted to allow fit of the slideway. The notch is defined by walls of which zones are in sliding abutment on the adjacent guiding faces of the slideway. The zones of abutment of the slider are formed by regular surfaces with generatrix parallel to the direction of displacement of the slider.

Window regulator for vehicle, comprising;
- a guide rail having a slideway,
- a window-bearing slider in which is made a notch adapted to a section of the slideway to allow fit of the slideway and guiding of the slider in a direction parallel to the slideway, the notch being defined by walls of which zones are in sliding abutment on the adjacent guiding faces of the slideway,
- wherein the zones of abutment of the slider are point contacts formed by regular convex surfaces disposed on either side of said slider with generatrix parallel to the direction of displacement of the slider.
