Definitions

  • the present invention relates to an electrically heated automobile window comprising, on one of its faces, narrow printed and baked heating conductors which are connected to collective conductors arranged along the edge of the glass and printed and baked at the same time as the heating conductors, metallic strips being arranged on the collective printed and baked conductors and being electrically connected thereto.
  • Heated glass panes fitted with such reinforcing strips brazed to collective conductors again have other drawbacks.
  • the metal strips applied to the surface represent obstacles during the handling, packaging and shipping of the panes and it can easily happen that in the event of an impact against the brazed metal strips, these deform in bending or that the brazed places let go.
  • such collective conductors reinforced by metal strips are particularly disadvantageous when the collective conductors are not disposed at the outer edge of the glass but at a certain distance from the frame of the glass inside the field of vision. , which is necessarily the case when the heating conductors are used at the same time as antenna conductors.
  • the collective conductors in particular must be placed at a distance of a few centimeters from the frame of the body, otherwise the capacity of the antenna conductor would become excessive.
  • a conductive network serving simultaneously as an antenna and a heating resistor it is advantageous to make the collective conductors which are entirely in the field of vision, as narrow as possible, which is possible in particular by reinforcement at by means of an additional metal strip.
  • the mounting of the additional metal strip is troublesome because this metal strip not only constitutes an obstacle, for example when cleaning the window, but also because above all there is a risk that the additional metal strip, during cleaning of the glass or in other circumstances, is requested to such an extent that the places of junction with the baked layer of collective conductors fail.
  • the object of the invention is to produce a heating glass of the type described, in such a way that the risk of damaging the additional metal strips and destroying the junction points between the metal strips and the cooked collective conductors is avoided with certainty. .
  • this object is achieved by the fact that the collective baked conductors and the metal strips which are connected thereto in a manner ensuring electrical conduction are provided with a coating of plastic material which covers them as a whole and which it is stuck to it as well as to the glass surface.
  • the metal reinforcing strip of a composite collective conductor is also, in accordance with the invention, completely embedded in a mass of plastic material which, for its part, adheres firmly and permanently to the baked layer of the collective conductors and to the glass surface immediately adjacent to the baked conductive layer.
  • the bonded coating guarantees additional mechanical fixing of the metal strip on the baked layer of collective conductors. Consequently, the electrically conductive junction with the layer of collective conductors can be carried out in a way which simply ensures a good electrical connection without having, moreover, to have a high mechanical strength. In this way it is now possible to also use electrical junctions which, as such, have insufficient mechanical strength because, thanks to the encapsulation of the collective conductors by means of the hardening plastic, the junction places show considerable mechanical consolidation and stabilization. In the case of a heating glass according to the invention, it is also possible to return to economic contacting methods without having to take into account the mechanical strength of the electrical junction.
  • the junction points must also not offer any particular resistance to chemical attack, for example to humidity, since they are optimally protected against such influences by complete encapsulation.
  • the heating glass shown in FIG. 1 is a heated rear window for a motor vehicle which, as such, is joined to the fixing wing of the bodywork by the direct bonding process.
  • the silicate glass pane 1 is provided, along its periphery, with a framing layer 2, generally a few centimeters in width, made of an opaque material, in particular a ceramic baking paint. .
  • a framing layer 2 generally a few centimeters in width, made of an opaque material, in particular a ceramic baking paint.
  • On this baked paint layer 2 are arranged collective conductors 3 from which the heating conductors 4 extend over the field of vision of the window.
  • the collective conductors 3 and the heating conductors 4 are made of an electrically conductive baking paint, are applied according to a current process in a single and same operation by screen printing on the glass surface or on the layer 2 previously applied and are baked in the course of heating necessary for the bending and / or tempering process of the glass.
  • a metal strip 6 is arranged on the collective conductor 3, preferably over its entire length.
  • the metal strip 6 can, for example, be a strip of copper sheet. Alternatively, the metal strip may be formed from a flat strand of copper or tinned copper. In the case of the embodiment shown, the metal strip 6 is applied in a slightly wavy form. At intervals, the metal strip 6 comes into contact with the baked collective conductor 3. At these contact points, the metal strip is joined together with a suitable junction material 7 to the baked collective conductor 3.
  • the junction material can for example be, as is usually done, a solder. It is however advantageous to replace the solder joint by a more economical method.
  • the well-known bonding process can be used in which the electrical conductive junction is produced as a welded junction using ultrasounds acting punctually. It is also possible to use as bonding materials electrically conductive or thermosetting adhesives.
  • a layer 8 of a hardening plastic which is united securely and sealingly to the layer 2, to the collective conductor 3 and to the metal strip 6.
  • the application of this layer plastic material 8 is advantageously carried out using a correspondingly calibrated extrusion nozzle which, by means of an appropriate device, is guided automatically along the window.
  • the adhesive material is thus deposited on the layer 2, the collective conductor 3 and the metal strip 6, envelops the metal strip 6 and, after hardening, adheres securely and durably to the layer 2, to the collective conductor 3 and to the metal strip 6.
  • a conventional adhesive composition which is also suitable for the present case, is, for example, a one-component polyurethane adhesive which cures with humidity, as described in US Patent No. 3 779 794.
  • the surfaces to which the adhesive is applied must be pretreated in a known manner using suitable cleaning agents and / or suitable compositions serving as base coats.
  • the application of the plastic layer 8 on the peripheral zone of the glass is advantageously carried out during the manufacture of the heating glass. In this way, it is possible to take full advantage of the advantages offered by the invention. As soon as the plastic layer 8 has hardened, the heating glass is ready for packaging and shipment to the automobile manufacturing plant.
  • the adhesive strip 10 necessary for bonding is applied using a extrusion nozzle on the plastic layer 8 and the glass is placed in the window opening.
  • the bead of adhesive 10 can be applied to the fixing wing in the window bay of the bodywork. Where appropriate, it is advantageous activate the surface of the cured adhesive layer before bringing the layer 8 and the adhesive bead 10 into contact.
  • FIG. 2 shows a heatable automobile window without peripheral coating in the form of a frame, which, for its assembly, is provided with a rubber frame.
  • the pane 11 is again provided on a surface with collective conductors 13 and heating conductors 14 printed and baked.
  • the collective conductors 13 are arranged parallel to the edge of the glass at a distance of several centimeters therefrom, so that, when the glass is installed in place, they are spaced at least 2 to 3 cm from the metal parts of window frame.
  • Such spacing of the collective conductors of the metal frame is necessary, when the electrical conductors 13, 14 must be used not only to heat the window, but also as antenna conductors, otherwise the capacity of the antenna conductor would become excessive.
  • a narrow metal strip 16 for example made of copper sheet.
  • This metal strip 16 extends over the entire length of the collective conductor 13 and is joined at the junction points 17 punctually to the collective conductor 13.
  • the junction points 17 can advantageously be arranged directly at the level of the individual heating conductors 14. In this way , the collective cooked conductors 13 essentially have the function of covering the metal strip 13 towards the outside.
  • the collective conductors 13 can thus be of an extremely narrow configuration.
  • Electrically conductive junctions 17 can again be carried out using suitable methods, for example by brazing, gluing or, in accordance with the known bonding method, using ultrasonic energy.
  • the metal strip 16 is bent at one end and shaped into a flat plug 19 by means of which, when the heating glass is installed in place, the electric power cable is connected via a corresponding connector.
  • the collective baked conductors 13 and the metal strip 16 which is electrically connected thereto are again covered with a layer of plastic material 18 applied in the form of a strip.
  • This layer of plastic material 18 is made, as in the previous embodiment, of an adhesive material suitable for extrusion, firmly and durably connected to the surface of the glass, to the collective conductors 13 and to the metal strip 16. It is applied to collective conductors using a suitable method, for example by means of a correspondingly calibrated extrusion nozzle, and using a device operating automatically to guide the extrusion nozzle. After the adhesive material has hardened, layer 18 represents ideal protection for collective conductors.
  • the electric heatable glass shown in FIG. 3 presents, with regard to the collective conductors 13 and the heating conductors 14 printed and baked on the glass 11, as well as the metal strips 16 reinforcing the collective conductors 13, the junction points 17, the plastic layer 18 covering the collective conductors and the flat plug 19, the same structure and the same configuration as the heatable glass shown in FIG. 2. It is however in this case prepared for direct bonding to the frame of the bodywork. To this end, the coating in the form of the usual opaque frame 20 is again placed on the peripheral zone. This coating in the form of a frame 20 may consist of any enamel suitable for this purpose or even also of a baking paint. On this coating 20 is disposed a layer of continuous adhesive which is shaped flat and hardened 21.
  • This layer of hardened adhesive 21 is also deposited using a correspondingly calibrated extrusion nozzle, which is guided along from the edge of the glass.
  • the profiled adhesive layer is provided, on the side facing the viewing surface of the window, with a substantially wedge-shaped lip 22.
  • this lip 22 is has a stop rib for the adhesive material which is deposited in the form of an extruded bead 23 on the hardened adhesive layer 21 or on the fixing flange of the window frame of the bodywork.
  • the lip 22 prevents the soft adhesive material from being pushed back towards the viewing surface of the glass. This measure not only has an aesthetic role, but is also important for technical reasons when the electrical conductors are to be used as antenna conductors.
  • an exit of the adhesive material from the adhesive bead 23 may, under certain circumstances, lead to a short circuit between the body and the antenna conductors, in particular when the plastic layer 18 also has a certain electrical conductivity. In the event of such a short circuit, the electrical conductors on the glass would no longer fulfill their antenna function.
