Abstract

Window wiper systems for motor vehicles are known in which the effective length of the wiper blade can be varied in order to be able to reach the corner areas of the windows. A window wiper system of this kind is to be optimised according to the invention in that a shorter additional wiper blade which extends in parallel with the wiper blade and is displaceably mounted is attached to the wiper blade in the area of its free end and can be displaced via a control which is dependent on the angle of swing.

Description

Scheibenwischesanlajie für KraftwagenWindshield wiper system for motor vehicles

Die Erfindung betrifft eine Scheibenwischeranlage, insbesondere Einarm-Scheibenwischeranlage, für Kraftwagen, deren Wischerblatt in seiner wirksamen Länge verstellbar ist.The invention relates to a windshield wiper system, in particular a single-arm windshield wiper system, for motor vehicles whose wiper blade is adjustable in its effective length.

Derartige Scheibenwischeranlagen sind z. B. der DE-OS 22 15 307 und der DE-OS 24 30 831 als bekannt zu entnehmen. Nachteilig bei diesen bekannten Anlagen ist einmal, daß zum Verschieben des gesamten Wischerblattes bzw. Wischerarms relativ hohe Kräfte erforderlich sind. Als weiterer Nachteil kommt noch hinzu, daß sich bei diesen Scheibenwischern die ungewischte Fläche im unteren, mittleren Bereich der Scheibe vergrößert.Such windshield wiper systems are z. B. DE-OS 22 15 307 and can be found in DE-OS 24 30 831 as known. These known systems are disadvantageous is once that for moving the entire wiper blade or wiper arm is relative high forces are required. Another disadvantage is that With these windshield wipers, the unwiped area in the lower, middle area of the disc enlarged.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine Scheibenwischeranlage für kraftwagen zu schaffen, deren Verstellantrieb keine Schwierigkeiten bietet und durch die ein optimales Wischfeld erreichbar ist.The present invention was therefore based on the object of addressing these disadvantages to avoid and to create a windshield wiper system for motor vehicles, their adjustment drive offers no difficulties and through which an optimal wiping field can be achieved.

Diese Aufgabe lird erfindungsgenräß dadurcll gelöst, daß im Bereich des freien Endes des Wischerblatts an diesem ein parallel dazu verlaufendes, verschiebbar gelagertes, kürzeres Zusatz-Wischerbiatt be festigt ist, das über eine schwenkwinkelabhängige Steuerung verschiebbar ist. According to the invention, this object is achieved in that in the area of the free end of the wiper blade on this one running parallel to it, displaceable stored, shorter additional wiper blade is fastened, which has a swivel angle dependent Control is movable.

In vorteilhafter Ausgestaltung der Erfindung ist dabei vorgesehen, daß das Verschieben des Zusatz-Wischerblatts über einen drucksteifen Seilzug erfolgt der über eine vom Wischermotor angetriebene Kurvenscheibe gesteuert wird. In an advantageous embodiment of the invention, it is provided that the displacement of the additional wiper blade takes place via a pressure-resistant cable which is controlled by a cam driven by the wiper motor.

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 schematisch eine Gesamtansicht einer erfindungsgemäß aufgebauten Scheibenwischeranlage, und Fig. 2 in größerem Maßstab das freie Erde eines dabei verwendeten Wischerblatts. In the drawing, Fig. 1 shows schematically an overall view of a Windshield wiper system constructed according to the invention, and FIG. 2 on a larger scale the free earth of a wiper blade used.

Im Bereich des freien Endes des in der Zeichnung dargestellten Wischerblatts 1 ist parallel zu diesem ein kürzeres Zusatz-Wischerblatt 2 befestigt und in seiner Halterung 3 verschiebbar gelagert. Die Steuerung der Verschiebebewegung erfolgt über einen drucksteifen Seilzug 's, der einerseits im Zusatz-Wischerblatt 2 gelagert ist und dessen anderes Ende - belastet durch eine Zugfeder 5 -an einer Kurvenscheibe 6 anliegt, die in nicht dargestellter Weise vo Wiscnermotor angetrieben wird. In the area of the free end of the wiper blade shown in the drawing 1, a shorter additional wiper blade 2 is attached parallel to this and in his Bracket 3 slidably mounted. The sliding movement is controlled Via a pressure-resistant cable, which is mounted on the one hand in the additional wiper blade 2 is and the other end - loaded by a tension spring 5 - on a cam 6 is applied, which is driven by Wiscner motor in a manner not shown.

Das auf der Windschutzscheibe 7 vom eigentlichen Wischerblatt 1 bestrichene Wischfeld ist in Fig. 1 der Zeichnung in durchgezogenen Linien dargestellt und mit 8 bezeichnet, während die Begrenzung des vom Zusatz-Wischerblatt 2 überstrichenen Feldes mit 9 bezeichnet und in unterbrochenen Linien dargestellt ist.That which is coated on the windshield 7 by the actual wiper blade 1 The wiping area is shown in solid lines in FIG. 1 of the drawing and with 8 denotes, while the boundary of the swept by the additional wiper blade 2 Field is denoted by 9 and shown in broken lines.

Es ist selbstverständlich, daß im Rahmen der Erfindung der Verschiebeantrieb des Zusatz-Wischerblatts auch auf andere, geeignete Weise erfolgen kann.It goes without saying that within the scope of the invention, the displacement drive of the additional wiper blade can also be done in other suitable ways.
