ABSTRACT:
A window frame assembly is provided with a sliding glass mechanism and seal system for vehicular backlites. The assembly includes a pair of fixed side windows secured in a frame in spaced-apart relationship, and one or more sliding windows positioned in channel brackets to close and open the aperture between the fixed window panes. A single gasket formed by a reaction injection molding process is formed around the periphery of the window assembly for mounting the window assembly in the opening of a body panel of a pickup truck. The gasket is integrally formed about the aperture during the reaction injection molding process and includes a flexible lip to engage the sliding window. The sliding window slides in the channels of the channel brackets and is positioned to engage the lip of the gasket to seal the aperture. The required sliding force to open and close the sliding window may be reduced by spring loading the sliding window in the channel. Channel guides with a spring mechanism are placed on the top and bottom edges of the sliding glass. A cam formed in the channel bracket is used to compress the springs and force the sliding glass window against the lip of the gasket to sealingly close the aperture. When the sliding window is in the range of open positions, the spring mechanism clears the cam and forces the sliding window away from the lip of the gasket to facilitate sliding of the glass.
