Description

Arm für die Scheibenwischer von Kraftfahrzeugen Die Erfindung betrifft einen Arm für die Scheibenwischer von Kraftfahrzeugen, der aus Kunststoff besteht und bei dem in einem Gehäuse am inneren Ende des Wischerarmes ein mit der Wischerwelle verdrehsicher zu verbindendes Spannstück schwenkbar gelagert ist, gegen das sich eine den Wischerarm gegen die Windschutzscheibe drückende Feder- legt.Arm for the windshield wipers of motor vehicles The invention relates to an arm for the windshield wipers of motor vehicles, which is made of plastic and with the one in a housing at the inner end of the wiper arm with the wiper shaft torsion-proof to be connected clamping piece is pivotably mounted against which a spring pressing the wiper arm against the windshield.

Bekannt ist ein Scheibenwischerarm, dessen sämtliche oder wenigstens wichtigste Teile aus durchsichtigem Kunststoff bestehen, wobei der Wischerarm aus drei Einzelteilen zusammengesetzt ist. Es soll damit bezweckt werden, die Sicht des Fahrers nicht zu beeinträchtigen. Dieser durchsichtige Wischerarm hat sich aber nicht bewährt; denn die Parkstellung eines Scheibenwischerarmes wird schon so gewählt, daß dieser außerhalb des Sichtfeldes des Fahrers liegt. Die Wischbewegungen selbst sind aber so schnell, daß auch durch einen undurchsichtigen Wischerarm kaum eine Sichtbehinderung entsteht.A windshield wiper arm is known, all or at least of which most important parts are made of clear plastic, with the wiper arm made of is composed of three individual parts. The purpose of this is the view not to affect the driver. This transparent wiper arm has, however not proven; because the parking position of a windshield wiper arm is chosen so that this is outside the driver's field of vision. The swipes themselves but are so fast that even with an opaque wiper arm hardly any Obstructed view arises.

DieVerwendung von Kunststoff für einen Scheibenwischerarm bietet jedoch große Vorteile, da seine Bestandteile ohne weiteres zu einem einstöckigen und formschönen Bauteil zusammengefügt werden können.However, the use of plastic for a wiper arm offers great advantages, since its components easily become a one-story and shapely Component can be joined together.

Die Erfindung besteht darin, daß der Wischerarm einschließlich des das Spannstück mit Feder aufnehmenden Gehäuses und der Wischblatthalterung einstöckig ist, über seine ganze Länge im wesentlichen einen U-förmigen Querschnitt hat, zwischen den Seitenwangen Versteifungen und Rippen aufweist und, sich vom äußeren nach dem inneren Ende hin allmählich verbreiternd, in das Gehäuse übergeht, in welchem zur schwenkbaren Lagerung des Spannstückes und zur Aufnahme der Druckfeder Vorsprünge, Vertiefungen und Löcher vorgesehen sind, während das äußere Ende des Wischerarmes ebenfalls auf der Innenseite seiner Seitenwangen zur schwenkbaren Lagerung des Wischblattes Vorsprünge hat, die unter vorübergehender elastischer Verformung in entsprechend ausgebildete Vertiefungen im Wischblatträger einrasten. Bei einer besonderen Ausführung ist in dem aus Kunststoff hergestellten Wischerarm eine Metalleinlage vorgesehen.The invention consists in that the wiper arm including the the clamping piece with the spring receiving housing and the wiper blade holder in one piece is, has a substantially U-shaped cross-section over its entire length, between the side cheeks has stiffeners and ribs and, from the outer to the gradually widening towards the inner end, merges into the housing in which the pivotable mounting of the clamping piece and projections to accommodate the compression spring, Depressions and holes are provided while the outer end of the wiper arm also on the inside of its side cheeks for the pivoting mounting of the wiper blade Has projections under temporary elastic deformation in accordance with Engage the recesses formed in the wiper blade carrier. With a special version a metal insert is provided in the wiper arm made of plastic.

Die Erfindung ist an zwei Ausführungsbeispielen erläutert. In der Zeichnung zeigt Fig. 1 einen Kunststoff-Scheibenwischerarm im Längsschnitt mit einem Teil des eingesetzten Wischblattes, Fig. 2 den Schnitt nach der Linie I-I der Fig. 1, Fig. 3 die Untenansicht des Wischerarmes und Fig.4 einen Kunststoff-Wischerarm mit Metalleinlage im Längsschnitt mit eingesetztem Spannstück und der Feder.The invention is explained using two exemplary embodiments. In the The drawing shows FIG. 1 a plastic windshield wiper arm in longitudinal section with a Part of the wiper blade used, FIG. 2 shows the section along the line I-I of FIG. 1, FIG. 3 the bottom view of the wiper arm and FIG. 4 a plastic wiper arm with metal insert in longitudinal section with inserted clamping piece and the spring.

Ein aus -einem hartelastischen Kunststoff hergestellter Wischerarm 1 ist im Querschnitt im wesentlichen U-förmig ausgebildet. Nach der Anschlußseite hin verbreitert sich dieser Wischerarm und bildet ein Gehäuse 2. In diesem Gehäuse sind Vertiefungen 3 und 4, Vorsprünge 5 und 6 sowie ein Loch 7 vorgesehen zur schwenkbaren Aufnahme eines Spannstückes 8 und einer Feder 9. Im Innern des U-Profils des Wischerarmes 1, also zwischen den Seitenwangen, sind Rippen 10 und Versteifungen 11 zur Verfestigung des Armes eingeformt. Zur schwenkbaren Aufnahme eines Wischblattes 12 sind an den Seitenwangen des äußeren Wischerarmendes 17 zwei Vorsprünge 13 und 14 angeordnet, die unter vorübergehender elastischer Verformung in ein Loch 15 im Wischblatt 12 einrasten.A wiper arm made of a hard-elastic plastic 1 is essentially U-shaped in cross section. After the connection side towards this wiper arm widens and forms a housing 2. In this housing recesses 3 and 4, projections 5 and 6 and a hole 7 are provided for pivoting Receipt of a clamping piece 8 and a spring 9. Inside the U-profile of the wiper arm 1, that is, between the side cheeks, ribs 10 and stiffeners 11 are used for reinforcement molded into the arm. To pivot a wiper blade 12 are on the Side cheeks of the outer wiper arm end 17 have two projections 13 and 14 arranged, which under temporary elastic deformation into a hole 15 in the wiper blade 12 snap into place.

Entsprechend der--Fig. 4 ist in dem Wischerarm 1' eine Metalleinlage 16 vorgesehen, die vorzugsweise den elastischen Teil des Wischerarmes ganz durchzieht.According to the - Fig. 4 is a metal insert in the wiper arm 1 ' 16 is provided, which preferably extends completely through the elastic part of the wiper arm.
