Patent attributes
A vehicular rear slider window assembly includes an upper rail and a lower rail and a fixed window panel. The rails are attached at an inner surface of the fixed window panel above and below an opening. First and second movable window panels are movable along the rails. The drive system includes a drive element at the first movable window panel, a gear element rotatably mounted at a rail of the window assembly, and first and second toothed tracks attached at the respective movable window panel and extending toward and overlapping the other movable window panel. When the drive system is operated, the drive element imparts movement of the first movable window panel along the rails. Movement of the first movable window panel causes a corresponding movement of the second movable window panel in an opposite direction along the rails via engagement of the gear element with the toothed tracks.
