Description
Stand der TechnikState of the art
Die Erfindung geht von einem Scheibenwischer und einem Tragelement einer Wischleiste nach den Oberbegriffen der Ansprüche 1 und 11 aus.The invention is based on a windshield wiper and a support element of a wiper strip according to the preambles of claims 1 and 11.

Offenbarung der ErfindungDisclosure of the invention
Nach der Erfindung bildet das Tragelement an seinem dem Wischarm zugewandten Ende einen von der Wischleiste abgewandten Bogen, der einen in der Verlängerung des Tragelements verlaufenden unteren Schenkel mit einem parallel zu diesem verlaufenden oberen Schenkel verbindet, dessen freies Ende am zugewandten Ende des Wischarms befestigt ist. Die Befestigung kann lösbar über eine Klippverbindung, z.B. einen Adapter, oder durch eine formschlüssige, kraftschlüssige oder stoffschlüssige Verbindung hergestellt werden.According to the invention, the support member forms at its end facing away from the wiper arm bow facing away from the wiper extending in the extension of the support member lower leg with a parallel thereto extending upper leg, the free end is attached to the facing end of the wiper arm. The attachment may be releasably connected via a clip connection, e.g. an adapter, or be made by a positive, non-positive or cohesive connection.
Bedingt durch die Krümmung der Scheibe ergibt sich, dass sich der Winkel der Welle zur Normalen der Scheibe am Innenkreis des Wischblatts während dem Wischen ändert. Diese Änderung bewirkt wiederum, dass sich der Winkel zwischen Wischarm und Wischblatt ändert. Diese Winkeländerung zwischen Wischarm und Wischblatt wird im Folgenden Verlaufswinkel genannt. Da die Einspannstelle des Wischblatts am Innenkreis kein Gelenk hat, erzeugt der Verlaufswinkel ein Moment. Um dieses Moment abzufedern, soll die Federschiene am Innenkreis länger ausgelegt werden, bevor der Wischgummi anfängt. Der Einfluss für die Anpresskraft des Wischgummis am Innenkreis wird dadurch minimiert. Um den Verlaufswinkel auszugleichen, wird die Federschiene im Bereich der Anbindung am Innenkreis des Wischblatts stark gebogen, z.B. in Form eines einbogigen, c-förmigen oder eines doppelbogigen, w-förmigen Bereichs. Diese Form bewirkt, dass sich das Moment nur gering mit dem Verlaufswinkel ändert. Um die Besonderheiten eines Kraftfahrzeugs leicht adaptieren zu können, ist es zweckmäßig, dass der Bogen am Innenkreis des Tragelements als separates Bauteil ausgelegt ist, z.B. optional inklusiv einem Adapter zur Montage des Wischblatts.Due to the curvature of the disc, it follows that the angle of the shaft to the normal of the disc on the inner circle of the wiper blade changes during wiping. This change in turn causes the angle between wiper arm and wiper blade to change. This angle change between the wiper arm and the wiper blade is referred to below as the course angle. Since the clamping point of the wiper blade on the inner circle has no joint, the course angle generates a moment. To cushion this moment, the spring rail on the inner circle should be designed longer before the squeegee begins. The influence on the contact force of the wiper blade on the inner circle is thereby minimized. To compensate for the course angle, the spring rail is strongly bent in the region of the connection to the inner circle of the wiper blade, e.g. in the form of a single-arched, c-shaped or double-arched, w-shaped area. This shape causes the moment to change only slightly with the course angle. In order to easily adapt the particularities of a motor vehicle, it is expedient that the arc is designed on the inner circle of the support element as a separate component, e.g. optionally including an adapter for mounting the wiper blade.
Gemäß einer Ausgestaltung der Erfindung besitzt das Tragelement einen Längsschlitz, der zumindest an einem Ende einstückig geschlossen ist. Dies ist zweckmäßigerweise das Ende, das dem Wischarm zugewandt ist. Dabei kann an dem anderen Ende eine Endkappe die durch den Schlitz gebildeten Schenkel relativ zueinander fixieren. Aus Stabilitätsgründen sowie aus schwingungstechnischen Gründen kann es zweckmäßig sein, dass der Längsschlitz versetzt zu einer Mittelebene des Tragelements verläuft.According to one embodiment of the invention, the support element has a longitudinal slot which is integrally closed at least at one end. This is expediently the end which faces the wiper arm. In this case, at the other end an end cap formed by the slot Fix the legs relative to each other. For reasons of stability as well as for reasons of vibration technology, it may be expedient that the longitudinal slot extends offset to a center plane of the support element.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing. In the drawings, embodiments of the invention are shown. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.
