Abstract: An articulating window assembly for a motor vehicle and a method of manufacturing thereof is disclosed, the window assembly comprising a windowpane, a hinge attachment means such as one or more mounting studs for securing the windowpane to a support structure. Preferably the hinge is composed of a unitary elastomeric material such as reaction injection molded polyurethane, having a first surface lying against the inner surface in a closed position. A first portion of such first surface is bonded to the windowpane. A second portion not bonded to the windowpane is spaced therefrom in an open position. Preferably the elastomeric hinge partially encapsulates mounting studs or the like. As the articulating window assembly pivots from a closed position to an open position there is local disengagement of the hinge member from the windowpane at the second surface portion, thereby reducing the stresses on the mounting studs with respect to the hinge.
