Wire-type door window regulator for an automotive vehicle

摘要

An improved wire-type door window regulator moves a window pane upward and downward relative to a door panel or body panel of an automotive vehicle in accordance with a rotating operation of a crank or electric motor. The wire-type door window regulator comprises: (a) a wire extending along an orbit in which the window pane moves upward and downward; (b) a wire driving mechanism to which the ends of the wire are secured and which winds and unwinds the wire so as to move the window pane to a desired elevation with respect to the door panel (window pane receiving well) according to the rotation thereof; (c) a substantially U-shaped-cross-sectioned guide rail member attached to the door inner panel or body panel and which extends in substantially the same direction as the motion of the window pane, having a longitudinal leg on each side thereof and one longitudinal leg being bent at a right angle to form a flange and the other longitudinal leg being folded backward by press working to form a guide runner; and (d) a mechanism for connecting the window pane to the wire for movement therewith having a substantially U-shaped-cross-sectioned groove matching the guide rubber so as to allow slidably the window pane to slide in the longitudinal direction of the guide rail member, a substantially L-shaped-cross-sectioned groove separate from the substantially U-shaped-cross-sectioned groove engaging the flange of the guide rail member, and a stop member for fixing the wire thereto. Therefore, the window pane can smoothly be moved upward and downward.
