Slide system mechanism and seal system for vehicular backlite

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 sealing lip of the gasket to seal the aperture. A channel liner continuously engages the horizontal edges of the sliding window to maintain the sliding window in tension in the channels. A leading edge gasket is formed on the vertical edge of the sliding window. The leading edge gasket is provided with a beveled outer edge to facilitate the movement of the sliding window past the sealing lip of the gasket.
