A transparent pane having an electrically heatable coating and at least one coating-free zone that can be used, for example, as a communication window, is disclosed. The electrically heatable coating is connected to two collecting electrodes, such that a supply voltage applied to the electrodes generates a heating current that flows via a heating field formed between the collecting electrodes, the heating field containing the coating-free zone whose zone-edge is formed, at least in sections, by the heatable coating. Other implementation details include subdivision of one of the two collecting electrodes into separated subregions, each connected, via an electrical supply line, to an additional electrode. In one case, the electrical supply line runs, at least in sections, in the coating-free zone, in a coating-free edge strip, in a subregion of the coating outside the heating field, and/or in the zone-edge. Methods for producing the transparent pane are also disclosed.

A pane having an electric heating layer is described, including at least: a first pane having a first surface; at least one electric heating layer that is applied to at least part of the surface and has an uncoated zone; at least two busbars, provided for connection to a voltage source, which are connected to the electric heating layer such that a current path for a heating current is formed between the busbars; and at least one separating line which electrically subdivides the electric layer into at least two segments. At least one segment is arranged in the form of a strip around the uncoated zone such that the current path for the heating current is at least partially guided around the uncoated zone.

A pane arrangement having an electrically heatable baffle plate is described. The pane arrangement has a pane having an enclosure on the inner side of the pane, a radiation receiver and/or a radiation source facing the pane within the enclosure such that a beam path of electromagnetic radiation passes through a predefined region of the pane, a baffle plate arranged within the enclosure and below the beam path, and an electrically heatable area in the baffle plate heating the region.

Disclosed is a heating element, including: a substrate; a first bus bar provided on the substrate; a second bus bar which is provided on the substrate so as to be opposite to the first bus bar; and a heating pattern which is provided to electrically connect the first bus bar and the second bus bar, wherein the heating pattern includes a first pattern region which is in contact with the first bus bar and a second pattern region which is in contact with each of the second bus bar and the first pattern region and the first pattern region has an opening region which serves as a communication window.

A pane having an electric heating layer is described, including at least: a first pane having a first surface; at least one electric heating layer that is applied to at least part of the surface and has an uncoated zone; at least two busbars, provided for connection to a voltage source, which are connected to the electric heating layer such that a current path for a heating current is formed between the busbars; and at least one separating line which electrically subdivides the electric layer into at least two segments.

A heated laminated windscreen including two sheets of glass joined by an inserted sheet, and including a system of conductive layers covering most of a surface of one glass sheet of the windscreen. The system is electrically powered by busbars at a top and bottom of the windscreen, with windows which are devoid of layers arranged at the top in the middle of the windscreen. The windscreen further including at least one additional busbar arranged laterally on edges and at the top of the windscreen.

An electrically-heated window sheet material includes a heatable transparent conductive film, and bus bars for supplying electricity to the transparent conductive film. The bus bars includes left and right bus bars connected to left and right edges of the transparent conductive film. The transparent conductive film includes a band-shaped first region interposed between the left and right bus bars, a band-shaped second region interposed between the left and right bus bars, and openings provided in the first region. A distance between the left and right bus bars is shorter in the first region than in the second region. The openings are arranged so that a current flowing in the first region from one of the left and right bus bars to the other of the left and right bus bars is bypassed at least once by the openings.

A heatable laminated vehicle window for separating a vehicle interior from an outer surrounding area is presented. The vehicle window includes an outer pane bonded to an inner pane via a thermoplastic intermediate layer. An electrically heatable coating of the vehicle window is electrically connected to two busbars such that by applying a supply voltage across the two bus bars, a heating current that forms heating field flows between the two busbars. In one aspect, a metal element is arranged on or in the vehicle window such that heat is dissipated out of a region of the heating field that has elevated heat generation by means of thermal conduction of the metal element.

A transparent pane having an electrically heatable coating and at least one coating-free zone that can be used, for example, as a communication window, is disclosed. The electrically heatable coating is connected to two collecting electrodes, such that a supply voltage applied to the electrodes generates a heating current that flows via a heating field formed between the collecting electrodes, the heating field containing the coating-free zone whose zone-edge is formed, at least in sections, by the heatable coating. Other implementation details include subdivision of one of the two collecting electrodes into separated subregions, each connected, via an electrical supply line, to an additional electrode. In one case, the electrical supply line runs, at least in sections, in the coating-free zone, in a coating-free edge strip, in a subregion of the coating outside the heating field, and/or in the zone-edge. Methods for producing the transparent pane are also disclosed.
