ABSTRACT:
A window frame of rubber, or the like covering material, has two U-shaped sealing strips at opposite surfaces of the window. A respective U-shaped cross-section reinforcing strip insert is embedded in each of the sealing strips. A bridge joins the legs of the two sealing strips near the window. The sealing strips and the bridge include projecting fingers which engage the window surface. The bridge is removed from the bottom of the window cutout, and the bridge instead hangs down to define guides for the sides of the window as it moves down. Each reinforcing insert is a high tensile and compressive strength metal strip, but is also flexurally elastic and is smooth on the outside and is developed approximately U-shaped in cross-section. The window frame has ends which are butted and butt vulcanized, with the butt vulcanization place being free of the reinforcement insert.
