Abstract
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.
