Abstract

The windscreen with ducted washer jets has the ducts (3) formed inside the inner layer (7) of the laminated structure. The ducts lead from one edge of the windscreen to outlets (4) spaced over the front. The ducts provide a supply of washer fluid directly under the wiper blades and require no high pressure pumps to direct jets from the bonnet fittings to the windscreen. The ducts are prevented from freezing by the windscreen heater system.

Description

"FaMrzeugscheibe""Vehicle disk"

Die Erfindung betrifft eine Fahrzeugscheibe, und zwar insbesondere eine aus Mehrschichtenglas bestehende FrOnt- oder Heckscheibe eines Kraftwagens.The invention relates to a vehicle window, in particular a front or rear window of a motor vehicle made of multilayer glass.

Zur Beaufschlagung derartiger Scheiben mit Waschflüssigkeit werden bis heute allgemein Düsen verwendet, die z. 8. auf der Motorhaube des Fahrzeugs oder im Bereich des Scheibenrahmens angeordnet sind. Aus diesen Düsen muß die Waschflüssigkeit unter relativ hohem Druck austreten, weil bei allen Fahrzuständen ein bestimmter Punkt der Scheibe vom Flüssigkeitsstrahl getroffen werden soll. Ein weiterer Nachteil dieser bekannten Anordnungen ist darin zu sehen, daß derartige Düsen im Winter zum Einfrieren neigen und deshalb an sich eine separate Heizung der Düsen erforderlich wäre. Ungünstig ist schließlich auch noch, daß für solche Düsen Befestigungslöcher z. B. in der Außenhaut der Karosserie vorgesehen werden müssen und daß ihre Montage aufwendig ist.To act on such panes with washing liquid to this day commonly used nozzles z. 8. on the hood of the vehicle or are arranged in the area of the window frame. The washing liquid must come from these nozzles exit under relatively high pressure, because there is a certain one in all driving conditions Point of the disc should be hit by the liquid jet. Another disadvantage these known arrangements can be seen in the fact that such nozzles in winter for Tend to freeze and therefore separate heating of the nozzles is required were. Finally, it is also unfavorable that there are mounting holes for such nozzles z. B. must be provided in the outer skin of the body and that their assembly is expensive.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, diese Nachteile der bekannten Anordnungen zu vermeiden und eine Möglichkeit zur Beaufschlagung von Fahrzeugscheiben mit Waschflüssigkeit zu schaffen, die besonders einfach aufgebaut und bei allen Witterungsverhältnissen betriebssicher ist.The present invention was therefore based on the object of addressing these disadvantages to avoid the known arrangements and a possibility of applying To create vehicle windows with washer fluid that are particularly simple and is safe to operate in all weather conditions.

Dies wird erfindungsgemäß dadurch erreicht, daß ausgehend von einer Kante derselben innerhalb der Scheibe mindestens ein Kanal zur Zuführung von Waschflüssigkeit angeordnet ist, der in eine Öffnung auf der Außenseite der Scheibe mündet.This is achieved according to the invention in that, starting from a Edge of the same inside the disk at least one channel for the supply of washing liquid is arranged, which opens into an opening on the outside of the disc.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The object of the invention is to be based on one in the Drawing illustrated embodiment will be explained in more detail.

In der Zeichnung zeigen Fig. 1 eine Vorderansicht einer erfindungsgemäß aufgebauten Fahrzeugscheibe, und Fig. 2 in größerem Maßstab einen Schnitt nach der Linie II - II in Fig. 1.In the drawing, FIG. 1 shows a front view of a device according to the invention constructed vehicle window, and Fig. 2 on a larger scale a section according to the Line II - II in FIG. 1.

In der in der Zeichnung dargestellten Fahrzeugscheibe 1 sind ausgehend von deren Unterkante 2 drei Kanäle 3 angeordnet, die an Stellen, an der nicht dargestellte Scheibenwischer die Waschflüssigkeit gut erfassen können, in Öffnungen 4 an der Vorderseite der Scheibe münden. Im dargestellten Ausführungsbeispiel besteht die Scheibe 1 aus zwei Glasschichten 5 und 6, die jeweils einen Teil jedes Kanals 3 bilden, und einer dazwischen angeordneten, aus Kunststoff bestehenden Zwischen£olie 7.In the vehicle window 1 shown in the drawing are based arranged by the lower edge 2 three channels 3, which are in places where the not shown Windshield wipers can capture the washer fluid well in openings 4 on the Open to the front of the disc. In the illustrated embodiment, there is the Disc 1 made of two glass layers 5 and 6, each part of each channel 3 form, and an intermediate layer made of plastic 7th

Der Flüssigkeitsdruck sollte bei einer derartigen Einrichtung vorzugsweise der jeweiligen Fahrzeuggeschwindigkeit angepaßt werden, d. h. er sollte bei stehendem Fahrzeug am niedrigsten und bei hoher Fahrgeschwindigkeit am höchsten sein.Fluid pressure should be preferred in such a device be adapted to the respective vehicle speed, d. H. he should be standing Vehicle at its lowest and highest at high driving speed.
