Transparent laminates with heating wires are known. In this case, the heating wire is provided in the synthetic resin layer between the lower plate and the upper plate. The lower and upper plates are usually glass plates with an intermediate layer of synthetic resin. Instead of a glass plate, other materials such as polymethyl-methacrylate-synthetic resin (PMMA) can be used. PMMA is a hard synthetic resin. Vinyl-butyl-aldehyde-resin is recommended as the material for the intermediate layer. A heating wire and a strip conductor are embedded in this resin. British Patent No. 97245
As described in U.S. Pat. No. 3, the heating conductor is mounted on the flat side of a plate of relatively stiff material, the heating conductor being embedded in the next layer. The material of this layer must be at least during fabrication to accommodate the heating wire.
It must be relatively soft.

The radius in this case is in the range of 20 mm or less. In the past, it was not possible to make an electrically heatable rear transparent plate for this kind of vehicle, so it was necessary to arrange a ventilation passage in the underbody of the automobile and to provide an additional heating fan. ..

The strip conductors are provided on both longitudinal edges of the heating conductor, and the strip conductors are covered by a covering film on the side of the lower plate and the upper plate, which covering film is more chemically than the material of the strip conductor. It is solved by being made of stable synthetic resin.

板の製作は一つの方法ステップで可能である。In the production of transparent plates, the lower cover film, the correspondingly cut heating conductors and the upper cover film are placed on the lower plate, and after the upper plate is attached the heating and cooling process. Can be pasted together. At that time, the heating conductors are fixed at the same time, and the two synthetic resin plates are connected so that they are permanently transparent and do not generate streaks. The production of the transparent plate is possible in one method step.

取りが達成される。The reaction between the material of the plate and the material of the strip conductor is prevented by the insertion of the covering film. If the covering film is dyed, for example in black, and extends over the entire edge area of the transparent plate, edging of the transparent plate is achieved, as is customary at present on glass plates.

可能な透明板とほとんど同じ機械的特性を有する。When the thickness of each of the lower and upper plates made of soft polyvinyl chloride is about 0.5 mm, the transparent plate according to the present invention, in terms of its flexibility, is a non-heatable transparent plate which is conventionally used. It has almost the same mechanical properties as.

取付けの前に対応する幅に切断することができる。If the heating conductor is formed as a fabric,
Its rational production is possible. Highly conductive wires extending in the warp direction are woven as strip conductors on both longitudinal edges of the fabric. In particular, the strip conductor extends substantially horizontally when the transparent plate is installed. Thereby, the heating conductor can be produced as a rollable textile strip of any length and cut to the corresponding width before mounting the transparent plate.

れている。The high electrical conductivity of the strip conductors at the longitudinal edges of the heating conductor is achieved when the wire is made of copper. In particular, the diameter of the strip conductor wire is larger than the diameter of the heating wire. When the woven fabric including the strip conductor is thinned by rolling, it is advantageous because the strip conductor does not project. As a result, in order to prevent the reaction between copper and polyvinyl chloride that occurs over time, the strip conductors are coated on the upper and lower flexible PVC plates, especially with an acrylate film. There is.

Below, especially with a mesh width of 0.5 mm, below 0.5 mm,
Especially when it consists of chrome-nickel wire with a diameter of less than 0.05 mm, the complete connection of the upper plate is made in the mesh when the upper plate is attached to the lower plate. Thereby very good transparency is obtained.

This is, for example, using lines with different thicknesses, using lines with different material compositions, arranging the lines with different intervals in the warp direction and the weft direction, woven fabrics with different shapes from the right-angle mesh shape, Alternatively, it is achieved by making the woven fabric non-conductive in the warp direction, in particular by using non-conductive lines or fibers extending in the warp direction.

It is recommended to adjust the resistance of the. The resistance of the heating conductor is interrupted in the region of the transparent surface of the heating conductor so as to at least electrically insulate transversely to the strip conductor by at least 1 degree, and one of the strip conductors likewise at least 1 degree. At least interrupted to provide electrical insulation, thereby forming at least two heating zones,
It is possible to increase. Thereby, the heating conductors are divided into resistance groups forming two or more heating ranges, which resistance groups are conductively connected to one another via strip conductors which respectively pass through the edge sections.

If an even number of heating conductor areas is formed, the electrical connections of the strip conductors can be mounted respectively near the outer edge of the lower side of the transparent plate.
