Die Erfindung geht aus von einem
Wischblatt nach dem Oberbegriff des Anspruchs 1. Bei einem bekannten
Wischblatt dieser Art (
Vorteile der ErfindungAdvantages of invention
Bei dem erfindungsgemäßen Wischblatt mit den kennzeichnenden Merkmalen des Anspruchs 1 befindet sich das Heizelement auf der von der Scheibe abgewandten Seite des Tragelements, welches als Schutzschild wirkend den Straßenschmutz weitgehend vom Heizelement fern hält.In the wiper blade according to the invention with the characterizing features of claim 1 the heating element on the side of the support element facing away from the pane, which acts as a protective shield largely from the street dirt from the heating element keeps away.
In Fortbildung der Erfindung ist das Heizelement mit einer Abdeckung versehen, so dass es gegen Umwelteinflüsse gekapselt vollständig geschützt ist.In development of the invention provide the heating element with a cover so that it is encapsulated against environmental influences Completely is protected.
Ein besonders kostengünstiger Anwendungsfall ergibt sich, wenn die Abdeckung als Windabweisleiste ausgebildet ist. Diese Ausführungsform der Erfindung bietet sich dann an, wenn das Wischblatt aufgrund anderer Kriterien ohnehin mit einer Windabweisleiste versehen sein muss.A particularly inexpensive Use case arises when the cover acts as a wind deflector strip is trained. This embodiment of the Invention lends itself when the wiper blade due to others Criteria must be provided with a wind deflector anyway.
In einem solchen Fall ergeben sich Vorteile bei der Montage eines gemäß dem Oberbegriff des Anspruchs 4 ausgebildeten Wischblatts, wenn das Heizelement zwischen dieser Dreiecksseite der Windabweisleiste und der dieser zugewandten Bandfläche des Tragelements angeordnet ist.In such a case arise Advantages when installing a according to the preamble of the claim 4 trained wiper blade when the heating element between this triangle side the wind deflector strip and the band surface of the Supporting element is arranged.
Dabei hat es sich als zweckdienlich erwiesen, wenn in Weiterbildung des Erfindungsgedankens die Windabweisleiste als separates Bauelement ausgebildet ist, wenn weiter die der Bandfläche zugewandte Dreiecksseite der Windabweisleiste mit einer sich in deren Längsrichtung erstreckenden Ausnehmung versehen ist und wenn darüber hinaus in dem sich so ergebenden Längskanal das vorzugsweise bandartige Heizelement untergebracht ist.It has come in handy proven if in further development of the inventive idea the wind deflector is designed as a separate component, if that further facing the belt surface Triangular side of the wind deflector strip with a lengthwise direction extending recess is provided and if beyond in the resulting longitudinal channel the preferably band-like heating element is housed.
Alternativ ist es aber auch denkbar eine sich in Längsrichtung der Wischleiste erstreckende Auskehlung in einem sich zwischen Windabweisleiste und Tragelement befindlichen Teil der Wischleiste anzuordnen, in welcher das Heizelement untergebracht ist. Selbstverständlich ist es auch denkbar das Heizelement in einem Raum unterzubringen, welcher durch eine entsprechende Ausnehmung in der Windabweisleiste zuzüglich einer entsprechenden Auskehlung der Wischleiste gebildet ist.Alternatively, it is also conceivable one in the longitudinal direction the wiper strip extending groove in a between the wind deflector and Arrange part of the wiper strip located in the support element, in which the heating element is housed. Of course it is also conceivable to accommodate the heating element in a room, which by a corresponding recess in the wind deflector strip plus one corresponding groove of the wiper strip is formed.
Bei einem Wischblatt, welches gemäß dem Oberbegriff des Anspruchs 7 ausgebildet ist, kann die angestrebte Erwärmung der Wischleiste bis zumindest in den Bereich des Kippstegs dadurch erreicht werden, dass ein zur Erwärmung der Wischleiste notwendiges Heizelement an der konvex gekrümmten Bandfläche des aus einem wärmeleitenden Material bestehenden Heizelement angeordnet ist.With a wiper blade, which according to the generic term of claim 7 is formed, the desired heating of Wiper strip can be reached up to at least in the area of the tilting bar that one for warming the wiper strip necessary heating element on the convex curved surface of the from a thermally conductive Material existing heating element is arranged.
Um die Betriebssicherheit eines derartigen Wischblatts zu erhöhen, ist das Heizelement mit einer Abdeckung versehen, welche gegebenenfalls durch eine entsprechend ausgebildete Windabweisleiste realisierbar ist.The operational safety of such a wiper blade to increase the heating element is provided with a cover, which if necessary by a correspondingly designed wind deflector bar can be implemented.
Bei einem Wischblatt gemäß dem Oberbegriff des Anspruchs 10 ergibt sich eine kostengünstige Lösung der eingangs geschilderten Problematik, wenn das Heizelement zwischen dieser Dreiecksseite der Windabweisleiste und der dieser zugewandten Bandfläche. des Tragelements angeordnet ist.With a wiper blade according to the generic term of claim 10 results in an inexpensive solution to the above Problem if the heating element between this triangle side the wind deflector strip and the belt surface facing it. of Supporting element is arranged.
Eine einfache Montage eines Wischblatts mit einer einzigen als Tragelement dienenden Federschiene – wie sie im Oberbegriff des Anspruchs 11 bezeichnet ist – ergibt sich dadurch, dass die der konkav gekrümmten Bandfläche des eine einzige Federschiene aufweisenden Tragelements zugewandte obere Fläche der Wischleiste mit einer nutartigen Längsauskehlung versehen ist, in welcher ein Heizelement untergebracht ist. Eine solche Anordnung ist natürlich auch denkbar, wenn das Wischblatt mit einer Windabweisleiste versehen sein muss.A simple assembly of a wiper blade with a single spring rail serving as a support element - as is referred to in the preamble of claim 11 - results from the fact that the upper surface of the wiper strip facing the concavely curved band surface of the support element having a single spring rail is provided with a groove-like longitudinal groove , in which a heating element is housed. Such an arrangement is naturally also conceivable if the wiper blade must be provided with a wind deflector strip.
Weitere vorteilhafte Ausgestaltungen und Einzelheiten der Erfindung sind der nachfolgenden Beschreibung zu entnehmen, in der die Erfindung anhand der in der Zeichnung dargestellten Ausführungsbeispiele näher erläutert ist.Further advantageous configurations and details of the invention are the following description to see in which the invention with reference to that shown in the drawing embodiments is explained in more detail.

Der dazu notwendige Wärmefluss in der Wischleiste kann – falls erforderlich – durch entsprechend hilfreiche Zuschläge zur Material-Ausgangsmischung für die Wischleiste verbessert werden. Denkbar ist dazu auch eine Wischleiste mit einer vergleichsweise gut wärmeleitenden Kernleiste, welche mit einer an der Scheibe anlegbaren Wischlippe aus einem für die Wischarbeit vorteilhaften Material versehen ist.The heat flow required for this in the wiper strip can - if required - by correspondingly helpful supplements to the starting material mix for the wiper strip can be improved. A wiper strip is also conceivable with a comparatively good thermal conductivity Core strip, which has a wiper lip that can be attached to the window from one for the wiping material is provided advantageous.
