Description

Die Erfindung bezieht sich auf einen Scheibenwisch-er, insbesondere für Kraftfahrzeuge, bei dem ein am Wischblattträger angelenkter zweischenkliger Federbügel über eine Rastverbindung lösbar gekuppelt ist mit dem diesen Bügel hakenförmig umgreifenden, umgebogenen Ende des Wischhebels, nach Patent 926 348.The invention relates to a windshield wiper, in particular for motor vehicles in which a two-legged arm hinged to the wiper blade carrier The spring clip is releasably coupled via a latching connection to the hook-shaped clip encompassing, bent end of the wiper lever, according to patent 926 348.

Bei den bekannten Scheibenwischern dieser Art ist der Schwenkbereich des zweischenkligen Federbügels nur durch den Wischblattträger begrenzt. Dadurch kann es vorkommen, daß der am Wischblattträger angelenkte Federbügel in einer um I8o° geschwenkten Stellung mit dem hakenförmigen Ende des Wischhebels zusammengesteckt wird, so daß die Rasteinrichtung nicht einrastet und deshalb eine sichere Verbindung zwischen Wischhebel und Wischblatt nicht zustande kommt.In the known windshield wipers of this type, the swivel range is of the two-legged spring clip is only limited by the wiper blade carrier. Through this it can happen that the spring clip hinged to the wiper blade carrier in a I8o ° pivoted position plugged together with the hook-shaped end of the wiper lever so that the locking device does not engage and therefore a secure connection does not come about between the wiper lever and the wiper blade.

Dieser Nachteil läßt sich erfindungsgemäß vermeiden durch einen Anschlag, der den Schwenkbereich des Federbügels derart begrenzt, daß der Bügel sich beim Zusammenstecken der Teile in der zum Herstellen der Rastverbindung richtigen Lage befinden muß.This disadvantage can be avoided according to the invention by a stop, which limits the pivoting range of the spring clip so that the bracket is when Put the parts together in the correct position to establish the locking connection must be located.

Weitere Merkmale der Erfindung sind unter Bezugnahme auf das gezeichnete Ausführungsbeispiel in der nachfolgenden Beschreibung näher erläutert sowie in den Ansprüchen enthalten.Further features of the invention are with reference to the drawn Embodiment explained in more detail in the following description and in the Claims included.

In der Zeichnung zeigt Fig. I eine Seitenansicht eines Wischblatts mit Wischhebel, Fig. 2 einen in größerem Maßstab dargestellten Ausschnitt aus Fig. I mit einem Teilschnitt durch die Kupplungsverbindung zwischen Wischhebel und Wischblatt, Fig. 3 einen Längsschnitt durch die Kupplungseinrichtung vor dem Zusammenstecken der Teile, Fig. 4 einen Längsschnitt durch den Lagerbock mit dem Federbügel in der einen und Fig. 5 den gleichen Schnitt mit dem Federbügel in der anderen Endstellung, Fig. 6 eine Draufsicht auf den Lagerbock.In the drawing, FIG. I shows a side view of a wiper blade with wiper lever, FIG. 2 shows a detail from FIG. I with a partial section through the coupling connection between the wiper lever and the wiper blade, 3 shows a longitudinal section through the coupling device prior to being plugged together of the parts, Fig. 4 is a longitudinal section through the bearing block with the spring clip in the one and FIG. 5 the same section with the spring clip in the other end position, 6 is a plan view of the bearing block.

An einem Wischblattträger I ist ein Wischblatt 2 aufgehängt. Auf dem Wischblattträger ist ein U-förmiger Lagerbock 3 befestigt, in dessen nach oben gerichteten Schenkeln eine das Wischblatt senkrecht kreuzende Achse 4 gelagert ist. Auf der Achse sitzt eine Buchse 5. Der Scheitelteil eines Federbügels 6 umfaßt diese Buchse.A wiper blade 2 is suspended from a wiper blade carrier I. On the A U-shaped bearing block 3 is attached to the wiper blade carrier, in its upwardly directed Legs an axis 4 perpendicularly crossing the wiper blade is mounted. On the Axis sits a bush 5. The apex part of a spring clip 6 includes this bush.

Der aus einem bandförmigen Metallstreifen bestehende Wischhebel 7 ist an seinem einen Ende in einem mit der Wischerantriebswelle 8 gekuppelten Halter 9 befestigt und am andern Ende hakenförmig umgebogen. Zum Verbinden des Wischhebels 7 mit dem Wischblattträger I wird, wie besonders aus den Fig. 2 und 3 ersichtlich, der am Wischblattträger I angelenkte Federbügel mit seinen beiden Schenkeln in das hakenförmig umgebogene Ende des Wischhebels 7 hineingeschoben. Dabei werden die Federschenkel entsprechend zusammengedrückt und eine aus dem einen Schenkel herausgedrückte Nase Io rastet schließlich in ein Loch II des Wischhebelendes sperrend ein.The wiper lever 7, which consists of a band-shaped metal strip is at one end in a holder coupled to the wiper drive shaft 8 9 attached and bent over like a hook at the other end. For connecting the wiper lever 7 with the wiper blade carrier I, as can be seen particularly from FIGS. 2 and 3, the spring clip articulated on the wiper blade carrier I with its two legs into the The end of the wiper lever 7, which is bent over in the shape of a hook, is pushed in. The Spring legs compressed accordingly and one pressed out of one leg Nose Io finally locks into a hole II of the end of the wiper lever.

Aus den Schenkeln des U-förmigen Lagerbocks 3 sind Nasen 12 herausgedrückt, die zwischen die Schenkel des Federbügels 6 hineinragen und dessen Schwenkbewegungen begrenzen, so daß der die Nase Io tragende Sehenkel des Federbügels 6 immer dem Steg des Lagerbocks 3 zugekehrt ist.Noses 12 are pressed out of the legs of the U-shaped bearing block 3, which protrude between the legs of the spring clip 6 and its pivoting movements limit, so that the bow of the spring clip 6 carrying the nose Io is always the one Web of the bearing block 3 is facing.
