Abstract

An articulated window panel for vehicles includes a glass sheet, a hinge or a latch mounting area on the inner surface of the sheet, and a hinge or a latch bonded to the hinge or latch mounting area by an adhesive such that there is no exposure of the hinge or latch on the outer surface of the glass sheet. The panel is preferably fitted in a generally vertical window opening of the vehicle such that the panel forms one of a side window, rear window, or lift gate window. The bonded hinge or latch resists failure due to severe vibration and extreme climatic conditions. A substantially opaque coating may be used between the hinge or latch and the glass sheet to aid in hiding those items from view from the outer sheet surface.
