  • Patent number: 4575967
    Abstract: The window glass closure for a vehicle window opening occupies a closed position in which its outer surface is substantially flush with the exterior surface of the door or other body portion in which the opening is provided. This is accomplished by guiding the upper edge of the window along a path inclined slightly outwardly of the vehicle as the window completes its upward movement from its lowered open position. It further comprises guiding the lower edge of the window along a path which is inclined substantially outwardly from the vertical as the window reaches upper position. Preferably this is effected by a generally vertical main guide track which receives a follower carried adjacent the upper edge of the window constrained to follow the main guide track. An abruptly inclined diversion track is connected with the main guide track which receives a follower carried adjacent the lower edge of the window and is adapted to depart from the main track and to enter the inclined diversion track portion.
