Scheibenwischer für Kraftfahrzeuge, Windscreen wipers for motor vehicles,
Die Erfindung betrifft einen Scheibenwischer für Windschutzscheiben Ton Kraftfahrzeugen«The invention relates to a windshield wiper for windshields Sound motor vehicles «
Wegen der unterschiedlichen Krümmung der Windschutzscheiben von Kraftfahrzeugen sind die Scheibenwischer im allgemeinen so gestaltet, daß ein durch eine Metallschiene verstärktes Wischblatt aus Gummi von einem Bügelsystem getragen wird, das aus einem Hauptbügel und daran angelenkten wagebalkenähnliehen Hilfsbügeln besteht. Ein Nachteil der Bügelsysteme besteht darin, daß sie im Winter durch Schnee und Eis ihre Wirkung leicht verlieren. Ein weiterer Nachteil sind Klappergeräusche, die durch die Metallteile bei verschiedenen Konstruktionen entstehen können.Because of the different curvature of the windshields of motor vehicles, the windshield wipers are generally designed so that a wiper blade made of rubber reinforced by a metal rail is carried by a bracket system consisting of a main bracket and there is a balance beam-like auxiliary bracket hinged to it. A disadvantage of the ironing systems is that they get through in winter Snow and ice easily lose their effect. Another disadvantage are rattling noises caused by the metal parts at various Constructions can arise.
Man hat deshalb vorgeschlagen, die Bügel durch elastische Kunststoff -Verbindungsglieder miteinander zu verbinden, jedoch ist das Herstellverfahren relativ umständlich.It has therefore been proposed that the bracket be made of elastic plastic -Connecting links to one another, but the manufacturing process is relatively cumbersome.
Es ist ferner eine Konstruktion ohne Hilfsbügel bekannt, bei der ein gleichmäßiges Anliegen des Wischblatts an die unterschiedlichen Krümmungen der Windschutzscheibe dadurch erzielt wird, daß das Wischblatt in gekrümmter Form gefertigt, durch einen vorgebogenen Metallstreifen verstärkt, und zwischen den Enden eines Metallbügels gespannt wird.There is also a construction without an auxiliary bracket is known in which a uniform fit of the wiper blade to the different curvatures of the windshield is achieved in that the Wiper blade made in a curved shape, reinforced by a pre-bent metal strip, and between the ends of a metal bracket is tensioned.
Der Erfindung liegt die Aufgabe zugrunde, die bekannten Konstruktionen zu vereinfachen und den Scheibenwischer unter Vermeidung einer Bügelkonstruktion mit angelenkten Hilfsbügeln so zu gestalten, daß er auch bei gekrümmten Scheiben einwandfrei arbeitet, eine niedrige Bauart aufweist und möglichst geräuschfrei arbeitet.The invention is based on the object of the known constructions to simplify and to design the windshield wiper while avoiding a bracket construction with hinged auxiliary brackets, that it works flawlessly even with curved panes, has a low construction and works as quietly as possible.

Diese Aufgabe wird dadurch gelöst, daß das Wischblatt fest verbunden ist mit einem aus elastischem Kunststoff bestehenden Wischerbügel, der entsprechend der Krümmung der Windschutzscheibe vorgeformt ist und in der Biegesteifigkeit senkrecht zur Wischflache nach den Enden zu abnimmt.This object is achieved in that the wiper blade is firmly connected is with a wiper bracket made of elastic plastic, which corresponds to the curvature of the windshield is preformed and in the flexural rigidity perpendicular to the wiping surface decreasing towards the ends.
In einer Gestaltung der Erfindung ist das Wischblatt in einer Hut des Wischerbügels befestigt.In one embodiment of the invention, the wiper blade is fastened in a hat of the wiper bracket.
In einer anderen Gestaltung ist Wischerbügel und Wischblatt aus einem Stück aus elastischem Kunststoff hergestellt.In another design, the wiper bracket and the wiper blade are made from one piece of elastic plastic.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt und werden im folgenden näher beschrieben. Es zeigenExemplary embodiments of the invention are shown in the drawing and are described in more detail below. Show it
Pig.1 einen Wischerbügel in Seitenansicht; Pig.2 einen Querschnitt durch einen Wischerbügel; Pig.3 einen Querschnitt durch einen Wischerbügel mit einerPig.1 a wiper bracket in side view; Pig.2 a cross section through a wiper bracket; Pig.3 shows a cross section through a wiper bracket with a
anderen Querschnittsgestaltung; Pig.4 einen Querschnitt durch einen Wischerbügel, bei dem Wischerbügel und Wischblatt aus einem Stück bestehen.other cross-sectional design; Pig.4 shows a cross section through a wiper bracket, in which The wiper bracket and wiper blade consist of one piece.
In Pig.1 ist der Wischerbügel 1 im mittleren ieil durch einen Steg 2 verstärkt. Die Biegesteifigkeit nimmt dadurch von der Mitte zu den Enden des Wischerbügels ab. Der Wischerbügel hat ein Ansatzstück 3 für eine Befestigung am nicht gezeichneten Wischerarm. Der Wischerbügel ist entsprechend der Krümmung der Windschutzscheibe vorgeformt, und zwar sind die Enden des Wischerbügels in unbelastetem Zustand zweckmäßig etwas stärker als die Scheibe gekrümmt, da der Druck des Wischerarms in der Mitte des Wischerbügels ansetzt. Durch die Vorformung und die geringe Biegesteifigkeit des Wischerbügels an den Enden wird bewirkt, daß das Wischblatt während des Wischvorgangs immer an der Scheibe anliegt.In Pig.1, the wiper bracket 1 is in the middle by a Bridge 2 reinforced. The bending stiffness thereby decreases from the center to the ends of the wiper bracket. The wiper bracket has an extension piece 3 for attachment to the wiper arm, not shown. The wiper bracket is corresponding to the curvature of the Preformed windshield, namely the ends of the wiper bracket in the unloaded state are appropriately somewhat stronger than that Windshield curved because the pressure of the wiper arm is in the center of the wiper bracket. Due to the preforming and the low The bending stiffness of the wiper bracket at the ends ensures that the wiper blade is always on the windshield during the wiping process is present.
Die Herabsetzung der Biegesteifigkeit zu einem oder beiden Enden des Wischerbügels hin entsprechend der Krümmung der Windschutzscheibe kann auch durch eine Verkleinerung der QuerschnittsflächeThe reduction in bending stiffness towards one or both ends of the wiper arm according to the curvature of the windshield can also be achieved by reducing the cross-sectional area

des Wischerbügels oder durch eine beliebige an sich bekannte Querschnittsform bewirkt werden.of the wiper bracket or by any known cross-sectional shape.
In Pig.2 ist 5 ein Wischerbügel, der in einer lint ein Wischblatt 6 aus Gummi trägt. Die Anordnung des Wischblatts in einer Mut ergibt eine niedrige Bauhöhe des Wischers. Das Wischblatt wird in der Nut abgestützt, so daß eine weiche Gummiqualitat Terwendet werden kann.In Pig.2, 5 is a wiper bracket, which is a wiper blade in a lint 6 made of rubber. The arrangement of the wiper blade in a courage results in a low overall height of the wiper. The wiper blade will supported in the groove, so that a soft rubber quality Terwendet can be.
Fig. 3 zeigt einen Wischerbügel 7 in einer aerodynamisch günstigen Querschnittsform. Das Wischblatt 8 ist in einer IJut des Wiscnerbügels 7 angeordnet. Schräge S'lächen 9 verhindern, daß das Wischblatt 8 sich über ein bestimmtes Maß hinaus seitwärts abbiegen kann.Fig. 3 shows a wiper bracket 7 in an aerodynamically favorable Cross-sectional shape. The wiper blade 8 is in an IJut of the Wiscner bracket 7 arranged. Inclined surfaces 9 prevent the wiper blade 8 from bending sideways beyond a certain amount can.
In ilfig.4 bestehen Wischerbügel und Wischblatt aus einem Stück. Dei Wischerbügel 10 läuft hier in eine dünne Wischleiste 11 als Wischblatt aus. Diese einfache Ji'orm kann Torteilhaft da verwendet werden, wo die Windschutzscheibe keine großen }{rümmungsunterschiede aufweist.In ilfig.4 the wiper bracket and wiper blade consist of one piece. The wiper bracket 10 runs here in a thin wiper strip 11 as Wiper blade off. This simple Ji'orm can be used in part be where the windshield does not have any great differences in curvature having.
