Abstract:
A cover unit for closing a roof opening in a motor vehicle roof comprising:a cover element composed of at least a partially transparent plastic, a reinforcing frame having a thermal expansion characteristic different from a thermal expansion characteristic of the cover element and which extends along a side edge of the cover element, and a seal supported by the reinforcing frame such that the seal surrounds the side edge of the cover element and is adapted to contact an essentially vertically extending, roof-mounted sealing surface of the roof, wherein the reinforcing frame is cemented with a flexible cement to the cover element such that the cover element can move relative to the reinforcing frame in a transverse direction in order to permit thermal expansion sliding of the cover element, and wherein the seal has a roof sealing area, for contact with the roof-mounted sealing surface, which is essentially unaffected by the thermal expansion sliding of the cover element, and wherein the seal has a cover sealing area providing compensation for the thermal expansion sliding of the cover element.
