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 Ebene (52) einen Winkel (α) einschließt, der in einem Bereich zwischen 10° und 25° liegt.The invention is based on a joint-free wiper blade (10) with a base body (18) on which a wiper lip (16) is formed and whose head strip (20) has a longitudinal channel (22) in which a spring-elastic support element (50) is embedded , wherein an adapter (32) for connecting the wiper blade (10) to a wiper arm, the head strip (20) in the region of the support member (50) laterally with claws (34) engages. It is proposed that the head strip (20) is roof-shaped thickened in cross-section on the side facing away from the wiper lip (16) and the thickening (48) forms an angle (α) in its lateral edge areas with a plane (52) running parallel to a vehicle window. which lies in a range between 10 ° and 25 °.
Description
Stand der TechnikState of the art
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.
Aus der
Ferner ist aus der
Es ergibt sich daraus die Aufgabe, ein besonders gutes Wischergebnis, insbesondere bei hohen Fahrgeschwindigkeiten, bei gleichzeitig niedrigem konstruktiven Aufwand zu erzielen.It results from the task of achieving a particularly good wiping result, in particular at high speeds, at the same time low design effort.
Gelöst wird diese Aufgabe bei einem gattungsgemäßen Wischblatt durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved in a generic wiper blade by the characterizing features of claim 1.
Vorteile der ErfindungAdvantages of the 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, the head strip of the wiper blade is thickened roof-shaped in cross-section on the side facing away from the wiper lip. The thickening drops off towards the longitudinal sides and forms in its lateral edge regions with an angle parallel to a vehicle window an angle which lies in a range between ten and twenty-five degrees. The adapter is adapted with its claws of the cross-sectional shape of the head strip and lies over the entire surface, in particular at the inclined to the vehicle window extending upper areas. It is held by claws which comprise the head strip in the region of the support element.
Gemäß einer Ausgestaltung der Erfindung ist an der Verdickung, die zweckmäßigerweise symmetrisch ausgebildet ist, ein Spoiler angeformt, dessen konkave Anströmfläche auf der Anströmseite tangential in die dachförmige Fläche der Verdickung 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 Abströmwinkel 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 one embodiment of the invention, a spoiler is formed on the thickening, which is expediently symmetrical, whose concave inflow surface runs tangentially on the inflow side in the roof-shaped surface of the thickening of the head strip, and the rear side forms a notch with the thickening. Since the lateral edge regions of the thickening with the vehicle window form an angle between ten and twenty-five degrees, the spoiler results in an optimum angle of incidence for the airstream. On the one hand the flow from the spoiler has been shown to come off when the angle of attack is less than ten degrees, on the other hand the pressure build-up at the spoiler decreases while the height of the spoiler remains the same if an angle of attack greater than twenty-five degrees is chosen. Furthermore, an outlet angle of at least eighty degrees at the trailing edge of the spoiler causes a good pressure build-up. This is achieved in that the inflow surface of the spoiler 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 as large as possible. According to one embodiment of the invention, however, the spoiler width is limited to the width of the head strip of the wiper blade, so that during extrusion the profile on the conveyor belt is less deformed.
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 Schneidfläche reichen, so dass mit einem Schneidmesser in einem kostengünstigen Verfahren 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 install the adapter, a window is usually cut into the spoiler and the adapter used. In order for the adapter to be tight and precise, the cut must be made very precisely. In the wiper blade according to the invention, according to one embodiment, the cut is made so that the sloping slopes of the thickening of the base body are preserved. This results in a narrow cutting surface, which does not need to be very accurate, because the adapter rests against the uncut bevels of the thickening of the body and has a good grip. The wiper blade may also be held well during cutting in a pick-up device. The receiving device can extend to close to the cutting surface, so that with a cutting blade in a cost-effective method sufficient cut quality can be achieved. Since the lateral edge regions of the base body against which the adapter rests can be identical for a wiper blade with a spoiler or without a spoiler, it is possible to use a same adapter for both wiper blade types.
