Abstract
In a glass lid (1) for a vehicle roof opening, the glass pane (2) is provided in its edge zone all around with a cast-on or foamed-on plastics border (3). At least at the longer sides of the glass pane (2), curved correspondingly to the roof curvature, stiffening profiles (4, 5) of steel, supporting the glass pane from below, are embedded into the border (3). The stiffening profiles (4, 5) have, before embedding, a curvature different from that of the glass pane and, in the completed lid (1), are elastically bent corresponding to the curvature of the glass pane so that they are embedded with prestress in the border (3), in order to counteract uplift forces acting upon the lid (1) while the vehicle is travelling, in the sense of maintaining the shape of the lid (1).
