Abstract

DC60 (01/02/48) A heated composite glass panel (1) with a trapezoidal outline and a heating area (2) which is formed in the composite glass panel and formed from heating wires (3) which are arranged in parallel and at least two supply bridges (4, 5) which electrically connect the ends of many heating wires (3) together in parallel and are arranged opposite each other along the lateral edges of the composite glass panel (1), which is parallel to each other with at least one supply bridge (4S, 5S; 8) protruding along the lateral edges in the area of the triangular outer surfaces of the trapezoidal outline and where at least one triangular outer surface of the trapezoidal outline is also used by additional heating wires (6) which can be electrically fed by the supply bridges (4S, 5; 5S; 8) and are arranged parallel to each other. A heated composite panel (1) with a trapezoidal shape and a heating area (2) is provided, along with at least two groups of heating wires connected in series. It is characterized by the fact that in at least one side of the triangular outer surface, heating wires (6) arranged in parallel and of different lengths are assembled into groups (6.1, 6.2, 6.3) connected in parallel, and at least two of these groups are connected in series such that the length of the wires that affect the main bridges is increased in order to uniformly heat the power in the triangular surface with the power of heating in the heating area (2). A heated composite panel (1) with a trapezoidal shape and a heating area (2) is formed in the composite panel and formed from the arranged heating wires (3) and the main bridges. At least two pieces (4, 5) which electrically connect the ends of the bulk heating wires (3) together in parallel and are positioned opposite each other along the lateral edges of the parallel composite pane (1), with at least one power bridge (4S, 5S; 8) protruding along the lateral edges in the area of the triangular outer surfaces of the trapezoidal outline, and where at least one triangular outer surface of the trapezoidal outline is also used by additional heating wires (6), which can be electrically fed by the power bridge (4S, 5; 5S; 8) and are positioned exactly parallel to and parallel to the heating wires (3) of the heating area (2), and together with at least two groups of heating wires which are electrically connected in series are also provided, with the characteristic that in the area of at least one triangular outer surface Heating wires (6), which are arranged in parallel and of different lengths, are assembled into groups (6.1, 6.2, 6.3) connected in parallel, and where at least two of these groups are electrically connected in series such that the length of the wires that affect the main bridges is increased in order to uniformly distribute the heating power across the triangular surface with the heating power in the heating area (2).
