Abstract
Die Erfindung geht von einem gelenkfreien Wischblatt (10) mit einem Grundkörper (18) aus, an dem eine Wischlippe (16) angeformt ist und dessen Kopfleiste (20) einen Längskanal (22) aufweist, in dem ein federelastisches Tragelement (50) eingebettet ist, wobei ein Adapter (32) zum Anschluss des Wischblatts (10) an einen Wischarm die Kopfleiste (20) im Bereich des Tragelements (50) seitlich mit Krallen (34) umgreift. Es wird vorgeschlagen, dass die Kopfleiste (20) im Querschnitt auf der der Wischlippe (16) abgewandten Seite dachförmig verdickt ist und die Verdickung (48) in ihren seitlichen Randbereichen mit einer zu einer Fahrzeugscheibe parallel verlaufenden Ebenen (52) einen Winkel (alpha) einschließt, der in einem Bereich zwischen 10 DEG und 25 DEG liegt.The invention relates to a joint-free wiper blade (10) with a base body (18) on which a wiper lip (16) is integrally formed and the head strip (20) of which has a longitudinal channel (22) in which a resilient support element (50) is embedded , An adapter (32) for connecting the wiper blade (10) to a wiper arm laterally engages the head strip (20) in the region of the support element (50) with claws (34). It is proposed that the head strip (20) be thickened in a roof shape in cross section on the side facing away from the wiper lip (16) and the thickening (48) in its lateral edge areas with an angle (alpha) with a plane (52) running parallel to a vehicle window. includes that is in a range between 10 DEG and 25 DEG.
Description
Die Erfindung geht von einem gelenkfreien Wischblatt nach dem Oberbegriff des Anspruchs 1 aus.The invention is based on a joint-free wiper blade according to the preamble of claim 1.

Vorteile der ErfindungAdvantages of invention
Nach der Erfindung ist die Kopfleiste des Wischblatts im Querschnitt auf der der Wischlippe abgewandten Seite dachförmig verdickt. Die Verdickung fällt zu den Längsseiten hin ab und bildet in ihren seitlichen Randbereichen mit einer zu einer Fahrzeugscheibe parallel verlaufenden Ebenen einen Winkel, der in einem Bereich zwischen zehn und fünfundzwanzig Grad liegt. Der Adapter ist mit seinen Krallen der Querschnittsform der Kopfleiste angepasst und liegt vollflächig, insbesondere an den zur Fahrzeugscheibe geneigt verlaufenden, oberen Bereichen an. Er wird durch Krallen gehalten, die die Kopfleiste im Bereich des Tragelements umfassen.According to the invention is the header of the wiper blade in cross section on that facing away from the wiper lip Roof-shaped side thickened. The thickening falls to the long sides towards and forms with one in its lateral edge areas a plane of a vehicle window parallel to an angle, which is in a range between ten and twenty-five degrees. The With its claws, the adapter is the cross-sectional shape of the header adapted and lies over the entire surface, especially on the upper, inclined to the vehicle window Areas. It is held by claws that hold the header include in the area of the support element.
Gemäß einer Ausgestaltung der Erfindung ist an der Verdikkung, die zweckmäßigerweise symmetrisch ausgebildet ist, ein Spoiler angeformt, dessen konkave Anströmfläche auf der Anströmseite tangential in die dachförmige Fläche der Verdikkung der Kopfleiste einläuft, und dessen Rückseite mit der Verdickung eine Einkerbung bildet. Da die seitlichen Randbereiche der Verdickung mit der Fahrzeugscheibe einen Winkel zwischen zehn und fünfundzwanzig Grad bilden, ergibt sich für den Spoiler ein optimaler Anströmwinkel für den Fahrtwind. Es hat sich gezeigt, dass sich die Strömung vom Spoiler einerseits ablöst, wenn der Anströmwinkel kleiner als zehn Grad ist, andererseits verringert sich der Druckaufbau am Spoiler bei gleich bleibender Höhe des Spoilers, wenn ein größerer Anströmwinkel als fünfundzwanzig Grad gewählt wird. Ferner bewirkt ein Anströmwinkel von mindestens achtzig Grad an der Abströmkante des Spoilers einen guten Druckaufbau. Dies wird dadurch erreicht, dass die Anströmfläche des Spoilers konkav ausgebildet ist.According to an embodiment of the invention at the thickening, which is convenient is formed symmetrically, a spoiler formed, the concave Inflow surface the upstream side tangential into the roof-shaped area the thickening of the header bar, and the back forms a notch with the thickening. Because the side edge areas the thickening with the vehicle window an angle between ten and twenty five Form degrees results for the Spoiler an optimal flow angle for the Wind. It has been shown that the flow of the Detaches spoiler on the one hand, if the approach angle is less than ten degrees, on the other hand the pressure build-up decreases on the spoiler with the height of the spoiler remaining the same, if a larger angle of attack than twenty five Degree selected becomes. A flow angle also causes a good one of at least eighty degrees on the trailing edge of the spoiler Pressure build-up. This is achieved in that the inflow surface of the Spoilers is concave.
Um einen möglichst großen Anpressdruck zu erreichen, sollte die Breite des Spoilers möglichst groß gewählt werden. Gemäß einer Ausgestaltung der Erfindung beschränkt sich jedoch die Spoilerbreite auf die Breite der Kopfleiste des Wischblatts, so dass beim Extrudieren das Profil auf dem Transportband weniger verformt wird.In order to achieve the greatest possible contact pressure, the width of the spoiler should be chosen as large as possible. According to one Embodiment of the invention, however, limits the spoiler width to the width of the header of the wiper blade, so that when extruding the profile is less deformed on the conveyor belt.
Zur Montage des Adapters wird in der Regel in den Spoiler ein Fenster ausgeschnitten und der Adapter eingesetzt. Damit der Adapter fest und präzise anliegt, muss der Schnitt sehr exakt durchgeführt werden. Bei dem erfindungsgemäßen Wischblatt wird gemäß einer Ausgestaltung der Schnitt so durchgeführt, dass die zu den Seiten abfallenden Schrägen der Verdickung des Grundkörpers erhalten bleiben. Dadurch ergibt sich eine schmale Schnittfläche, die nicht besonders genau zu sein braucht, weil der Adapter an den nicht geschnittenen Schrägen der Verdickung des Grundkörpers anliegt und einen guten Halt besitzt. Das Wischblatt kann außerdem während des Schneidens in einer Aufnahmevorrichtung gut gehalten werden. Die Aufnahmevorrichtung kann bis dicht an die Schnetdfläche reichen, so dass mit einem Schneidmesser in einem kostengünstigen Verfah ren eine ausreichende Schnittqualität erreicht werden kann. Da die seitlichen Randbereiche des Grundkörpers, an denen der Adapter anliegt, bei einem Wischblatt mit einem Spoiler oder ohne einen Spoiler identisch sein können, besteht die Möglichkeit, für beide Wischblatttypen einen gleichen Adapter zu verwenden.To mount the adapter, in usually cut out a window in the spoiler and the adapter used. The cut must be made so that the adapter fits tightly and precisely performed very precisely become. In the wiper blade according to the invention is according to one Shaping the cut so that the sides sloping slopes the thickening of the body remain. This results in a narrow cut surface that does not need to be particularly precise because the adapter on the not cut bevels the thickening of the body fits and has a good grip. The wiper blade can also during the Cutting can be held well in a cradle. The Pick-up device can reach close to the cutting surface, so that with a cutting knife in an inexpensive process, an adequate cutting quality can be achieved. Since the lateral edge areas of the body, on to which the adapter is attached, for a wiper blade with a spoiler or can be identical without a spoiler, there is the possibility for both Wiper blade types to use the same adapter.
