Wischvorrichtung für Scheiben von Kraftfahrzeugen Stand der Technik Wiper device for windows of motor vehicles State of the art
Bei "bestimmten Witterungsbedingungen, insbesondere bei gefrierendem Regen, vereisen die Gelenke der Tragsysteme, so daß sich das Wischblatt nicht mehr der Scheibenkrümmung anzupassen vertrag, wodurch das Sichtfeld des Fahrers extrem eingeengt -wird. Um diesem Mangel abzuhelfen hat man bei einer bekannten Wischvorrichtung das Heizelement im Wischelement untergebracht. Dadurch kann aber lediglich die Flexibilität des Wischelements auch bei Eisregen erhalten werden. Die Vereisung der Gelenke des Tragsystems wird dadurch aber nicht verhindert.In certain weather conditions, especially freezing rain, the joints of the support system freeze, so that the wiper blade can no longer adapt to the curvature of the windshield, which severely restricts the driver's field of vision. To remedy this problem, a known wiper device has a heating element housed in the wiper element. This only allows the flexibility of the wiper element to be maintained even in freezing rain. This does not prevent the joints of the support system from freezing.
Um einen zuverlässigen Schutz gegen Vereisung der Gelenke zu erreichen, ist es bekannt, das gesamte TragsysteÄ mit einer am Wischelement befestigbaren Hülle zu umgeben. Durch diese Maßnahme wird jedoch das aerodynamische Verhalten des Wischblatts, insbesondere bei höheren Fahrgeschwindigkeiten* problematisch.In order to achieve reliable protection against icing of the joints, it is known to surround the entire support system with a cover that can be attached to the wiper element. However, this measure makes the aerodynamic behavior of the wiper blade problematic, especially at higher driving speeds*.

Ausführungsheispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 einen Scheibenwischer gemäß der Erfindung in Seitenansicht, mit schematisch eingezeichneten Heizelementen, Figur 2 die Querschnittsfläche eines Tragsystemteils, entlang der Linie II-II in Figur 1 geschnitten, in vergrößerter Darstellung, Figur 3 die Querschnittsfläche gemäß Figur 2 durch ein anders ausgebildetes Tragsystemteil und Figur k einen Schaltplan für ein Wischblatt gemäß Figur 1, bei dem zusätzlich das flexible Wischelement beheizt ist.Embodiments of the invention are shown in the drawing and explained in more detail in the following description. Figure 1 shows a windshield wiper according to the invention in side view, with schematically drawn heating elements, Figure 2 shows the cross-sectional area of a support system part, cut along the line II-II in Figure 1, in an enlarged view, Figure 3 shows the cross-sectional area according to Figure 2 through a differently designed support system part and Figure k shows a circuit diagram for a wiper blade according to Figure 1, in which the flexible wiping element is additionally heated.
Beschreibung der AusführungsbeispieleDescription of the embodiments
Figur 1 zeigt ein Wischblatt 10 zu dem ein Tragsystem 12 gehört, welches beim Ausführungsbeispiel aus zwei Krallenbügeln 1H und einem die beiden Krallenbügel verbindenden Hauptbügel 16 besteht. Zum Wischblatt 10 gehört ferner ein langgestrecktes, flexibles Wischelement 18, das von Krallen 15 der beiden Krallenbügel 1U gehalten ist. Das Wischblatt ist am freien Ende eines angetriebenen Wischerarms 20 angelenkt. Das Tragbügelsystem 12 dient zum Verteilen des Anpreßdruckes auf das Wischelement 18, damit dieses mit einer vorbestimmten Kraft an der zu wischenden Scheibe angelegt ist. Der Hauptbügel 16 ist über Gelenke 22 mit den Krallen-Figure 1 shows a wiper blade 10 to which a support system 12 belongs, which in the embodiment consists of two claw brackets 1H and a main bracket 16 connecting the two claw brackets. The wiper blade 10 also includes an elongated, flexible wiping element 18, which is held by claws 15 of the two claw brackets 1U. The wiper blade is hinged to the free end of a driven wiper arm 20. The support bracket system 12 serves to distribute the contact pressure on the wiping element 18 so that it is applied to the window to be wiped with a predetermined force. The main bracket 16 is connected to the claw brackets via joints 22.

daß sieh das Wischelement 18 auch sphärisch gekrümmten
Scheiten anzupassen vermag, wenn es quer zu seiner ErstrekkungsrichtUng
über die Scheibe bewegt wird. Dazu ist es
auch erforderlich j daß das Wischelement 18 in den Krallen■iron 1 H. The joints 22 ensure that
that the wiping element 18 also has spherically curved
logs when it is moved across the disk transversely to its direction of extension. For this purpose, it is
also necessary j that the wiping element 18 in the claws
15 der Krallenbügel 1k zumindest um ein bestimmtes Maß15 the claw bracket 1 k at least by a certain amount
in Längsrichtung verschiebbar ist. Wie Figur 2 zeigt, hat der Hauptbügel 12 einen im wesentlichen U-förmigen Querschnitt. Einen entsprechenden Querschnitt können auch die beiden Krallenbügel lk aufweisen. Zum Beheizen des Bügelsis displaceable in the longitudinal direction. As shown in Figure 2, the main bracket 12 has a substantially U-shaped cross-section. The two claw brackets lk can also have a corresponding cross-section. To heat the bracket
16 sind in dem von der U-Form des Bügels 12 umschlossenen Kanal, nahe den Gelenken 22> zwei Heizelemente 2k untergebracht, die in dem Kanal'in einer Vergußmasse 25, vorzugsweise Polyesterharz, eingebettet sind. Eine entsprechende Ausgestaltung ist in den Krallenbügeln Ik vorhanden. Dort sind je zwei Heizelemente 27 beidseitig an Gelenke 22 angeordnet und vergossen.16, two heating elements 2k are housed in the channel enclosed by the U-shape of the bracket 12, near the joints 22>, which are embedded in the channel in a casting compound 25, preferably polyester resin. A corresponding design is present in the claw brackets Ik . There, two heating elements 27 are arranged on each side of the joints 22 and cast.
Abweichend von dem beschriebenen Ausführungsbeispiel kann
der Querschnitt der Bügel 16 bzw. lU V-förmig sein, so wie
dies in Figur 3 gezeigt ist. In diesem Fall sind die Heiselemente 2k und 27 in dem von der V-Form umschlossenen
Kanal angeordnet.Deviating from the described embodiment, the cross section of the brackets 16 and 1U can be V-shaped, as shown in Figure 3. In this case, the heating elements 2k and 27 are in the area enclosed by the V-shape
channel arranged.
Durch die erfindungsgemäße Ausgestaltung wird erreicht, daß
die Gelenke 22 auch bei extremen Witterungsbedingungen
gangbar bleiben. Wenn nämlich die Heizelemente 2k und 27
über ihre Zuleitung 26 an einer Stromquelle angeschlossen sind, wird die von den Heizelementen erzeugte Wärme auf
die aus einem wärmeleitfähigen Material bestehenden Bügel
^k, 16 gebracht und gelangt somit in die Gelenke 22.The design according to the invention ensures that the joints 22 remain in place even under extreme weather conditions
remain viable. If the heating elements 2k and 27
are connected to a power source via their supply line 26, the heat generated by the heating elements is
the brackets ^k, 16, which are made of a thermally conductive material, and thus reaches the joints 22.
Um auch das Wischelement 18 flexibel zu halten, ist gemäß der Ausführungsform gemäß Figur 2 in dem WischelementIn order to keep the wiping element 18 flexible, according to the embodiment according to Figure 2,
