Die Neuerung betrifft eine Heizfolie für elektrische Scheibenheizung, bei der eine transparente isolierende Folie mit Widerstandsbelägen als Heizleiter an der zu heizenden Scheibe mittels Klebstoff befestigt ist. Hierbei war die Scheibe bisher nur an einer Seite mit Widerstandsbelägen versehen und mit dieser Seite an der zu heizenden Scheibe festgeklebt. Dies hatte den Nachteil, daß die Folie nicht über ihre gesamte Fläche gleichmäßig erwärmt wurde und dadurch sich von der zu heizenden Scheibe ablöste.The innovation concerns a heating foil for electric window heating, in which a transparent insulating film with resistance coatings as a heating conductor on the pane to be heated by means of Adhesive is attached. In this case, the disk was previously only provided with resistance coatings on one side and with this Side glued to the pane to be heated. This had the disadvantage that the film was not uniform over its entire surface was heated and thereby detached itself from the pane to be heated.
Gemäß der Neuerung wird dieser Nachteil in einfachster Weise dadurch beseitigt, daß beide Seiten der Folie mit Widerstandsbelägen versehen sind. Die Widerstandsbeläge sind so bemessen, daß die Folie über ihre gesamte Fläche gleichmäßig erwärmt wird. Um dies zu erzielen, ist es vorteilhaft, die von der zu heizenden Scheibe abgewandte Seite der Folie in der Nähe der Stromanschlußstellen mit weniger Widerstandsbelägen als die andere Seite der Heizfolie zu versehen.According to the innovation, this disadvantage becomes the simplest eliminated in that both sides of the film are provided with resistance coatings. The resistance coverings are dimensioned in such a way that that the film is heated evenly over its entire surface. To achieve this, it is advantageous to use the side of the film facing away from the pane to be heated near the power connection points with less resistance layers than to provide the other side of the heating foil.
In den Fig. 1 und 2 ist die Neuerung an einem Beispiel einer Heizfolie für die Beheizung einer Heckscheibe von Kraftfahrzeugen dargestellt.In FIGS. 1 and 2, the innovation is based on an example of a heating film for heating a rear window of a motor vehicle shown.
Die Fig. 1 zeigt die von der zu heizenden Scheibe angewandte Seite der Heizfolie in Ansicht;Fig. 1 shows that applied by the pane to be heated Side of the heating foil in view;
in Figo 2 ist die Heiafolie im Schnitt vergrößert dargestellt.in FIG. 2 the foil is shown enlarged in section.
Die Folie 1 bestellt aus einem klar durchsichtigen Kunststoff, z.B. aus Acetat, und ist mit mehreren Widerstandsbelägen 2, z.B. aus Leitsilberpaste, versehen. Das Auftragen kann im Siebdruck erfolgen. The film 1 is made of a clear, transparent plastic, for example made of acetate, and is provided with several resistance coatings 2, for example made of conductive silver paste. The application can be done by screen printing.
Diese Widerstandsbeläge 2 sind neuerungsgemäß auf beiden Seiten quer über die gesamte Breite der Folie aufgebracht. Sie sind an den Rändern durch Anschlußbeläge 3> 4 verbunden.According to the innovation, these resistance coatings 2 are applied across the entire width of the film on both sides. They are connected at the edges by connecting pads 3> 4.
Der Stromanschluß erfolgt durch Druckknöpfe 5» 6, die beide durch eine dünne metallische Unterlagscheibe 7 und 8 mit den seitlichen Anschlußbelägen 3 und 4 in guter elektrischer Verbindung stehen. In der Nähe der Anschlußdruckknöpfe 5 und sind die quer verlaufenden Widerstandsbeläge 2 wegzulassen, damit die Folie im unteren Teil nicht stärker erhitzt wird als der übrige Teil der Folie.The power connection is made by push buttons 5 »6, both of them through a thin metallic washer 7 and 8 with the side connection pads 3 and 4 in good electrical Connected. In the vicinity of the connection push buttons 5 and, the transverse resistance linings 2 are to be omitted, so that the lower part of the film is not heated more than the rest of the film.
