Abstract:
1. Automotive vehicle having an aperture in the vehicle body in which a glazing, comprising a switchable film laminated between at least two plies of an interlayer material, the plies of interlayer material being laminated between a first ply of glazing material facing out of the vehicle and a second ply of glazing material facing into the vehicle, is fitted, the switchable film comprising first and second electrodes, both in electrical connection with a power supply, wherein the first electrode is capacitively connected to electrical ground on the vehicle body, wherein the capacitive connection comprises a capacitor formed from the first electrode and an electrically conductive element, and wherein the electrically conductive element comprises at least one of a functional coating on a portion of one surface of at least one ply of glazing material, a ply of polymer material having a functional infrared coating that is laminated between the switchable film and the first ply of glazing material, a busbar connected to a non-electrically conducting surface of the first electrode, and a part of the vehicle body that extends into the aperture to overlap the first electrode.
