A vehicle roof (1) having a cover (3) which, selectively, can close or at least partially expose a roof opening (2). A liner (6) which is made of a waterproof transparent material is slidably arranged below the cover (3). Contrary to a known design, in which the transparent liner, in combination with an opaque cover, does offer a variety of options regarding light transmission of the entire vehicle roof, the vehicle roof of the present invention provides an additional ventilation possibility, in that the liner (6) has ventilation openings (21) which are designed to prevent water penetration. The ventilation openings, preferably, have rearward facing slots (23) and can selectively be exposed or closed by way of movable parts (24).

Vehicle roof

A panel system with variable light transmissiveness is formed of two essentially parallel transparent panels, and a seal encircling both panels. A cavity, defined by the panels and the seal, communicates with a liquid reservoir, from which liquid can be conveyed into the cavity by a transport element for the purpose of changing the distance between the panels by changing the thickness of the liquid layer between the panels. In order to render the panel system suitable for usage in a cover of a vehicle sliding/lifting roof, the liquid reservoir and the transport element, which is driven by a pole-reversible electric motor, are supported at an inner cover plate, which has an undercut in an edge portion in which an electrical contact element for establishing a conductive connection between the electric motor and the vehicle battery is disposed.

Panel system with variable transparency

Transparent pane for vehicles, in particular, a transparent cover for sliding roofs, lifting roofs and the like, with a transparent outer layer and a solar laminate lying flat against the inside of this outer layer. The active part of the solar laminate is formed of a first subsection lying in the outer edge area of the pane which is made of crystalline semiconductor material, and a second subsection that is made of an amorphous semiconductor material.
