Abstract
A cover unit, for closing the roof opening in the solid skin of a motor vehicle roof, having a cover element, composed of an at least partially transparent plastic, and a reinforcing frame, for example, made of metal, which extends along the side edge of the cover element, and which bears a seal which surrounds the side edge of the cover element for contact against an essentially vertically running roof-mounted sealing surface. The reinforcing frame is cemented, using a flexible cement, to the cover element such that the cover element can move, in the transverse direction, relative to the reinforcing frame in order to enable thermal expansion of the cover element. The seal has a roof sealing area, contacting a roof-mounted sealing surface, which is substantially unaffected by thermal expansion of the cover element, and the seal has a cover sealing area for compensation of thermal expansion of the cover element.
