Abstract: A sliding window panel assembly for a motor vehicle. The assembly includes a stationary window panel having an opening formed therein, at least one guide rail coupled to the stationary window panel below the opening and above a bottom edge of the stationary window panel, a shoe slidably received within the guide rail and configured to slidably move within the guide rail, a movable window panel mounted onto the shoe such that the movable window panel slidably moves with the shoe. The movable window panel can slidably move with respect to the stationary panel along a movable panel path. The lead screw drive unit engages the shoe and is adapted to move the shoe and the movable panel along the movable panel path within the guide rail.

Abstract: A slider window assembly for an automotive vehicle comprises a fixed glass panel adapted to be installed in a window frame defined by a body panel. The fixed glass panel is bonded to the window frame by an adhesive bead and defines an opening. A sliding window opens and closes the opening and includes an edge that is received in a guide rail that is adhesively bonded to the fixed glass panel. The guide rail defines a channel for the edge of the sliding window and also includes an extension that is bonded to the window frame by the adhesive bead. In this manner, the guide rail continues to support the sliding window in the event that the fixed glass panel is unable to provide the primary support function.
