Abstract
Description
Die Erfindung betrifft ein Wischerblatt mit integrierten Heizelement zum wischen von Scheiben insbesondere in der Automobiltechnik.The The invention relates to a wiper blade with integrated heating element for wiping windows, in particular in the automotive industry.
Einem Autofahrer soll bei feuchten Witterungsverhältnissen eine gute Sicht durch die Windschutzscheibe ermöglicht werden.a Motorists should have a good view in damp weather conditions the windscreen allows become.
Es ist bekannt , dass zur Erfüllung dieser Erfordernisse ein Wischerblatt über die Windschutzscheibe streift und vorhandene Wassertropfen zur Seite wischt. Diese laufen dann an der Scheibe nach unten.It is known to be fulfilling These requirements wipes a wiper blade on the windshield and wipes existing drops of water aside. These then run at the disc down.
Zum Stand der Technik gehört, dass beim Wischvorgang sich das Wischblatt der Form der Windschutzscheibe anpasst.To the State of the art is heard, that during wiping, the wiper blade of the shape of the windshield adapts.
Bei Minusgraden und Schneetreiben kommt es vor, dass der Schnee an der Windschutzscheibe taut. Diese Wassertropfen werden vom Wischerblatt weggewischt, gefrieren dann aber am Wischerblatt und können eine Eisschicht bilden.at Temperatures below freezing and snowfall, it happens that the snow at the Windscreen thaws. These drops of water are wiped away from the wiper blade, but then freeze on the wiper blade and can form an ice layer.
Dieser Umstand kann dazu führen, dass das Wischerblatt in einer bestimmten Form verharrt und sich beim wischen nicht mehr der Form der Windschutzscheibe anpasst. Dies führt wiederum dazu, das an bestimmten Stellen der Windschutzscheibe die Wassertropfen nicht mehr weggewischt werden. Der Fahrer ist dann in seiner Sicht behindert.This Circumstance may cause that the wiper blade remains in a certain shape and is when wiping no longer adapts to the shape of the windshield. this leads to turn to that in certain places of the windshield the Water drops can not be wiped off. The driver is then hampered in his view.
Der Erfindung liegt die Aufgabe zugrunde, auch unter diesen widrigen Umständen einem Autofahrer eine gute Sicht zu gewährleisten.Of the Invention is based on the object, even among these adverse circumstances to ensure a good view of a motorist.
Diese Aufgabe wird Erfindungsgemäss dadurch gelöst, dass über die gesamte Länge des Wischerblattes ein elektrisches Heizelement integriert ist.These Task is according to the invention solved by that over the entire length the wiper blade an electric heating element is integrated.
Um das Wischblatt unter den beschriebenen Umständen Eisfrei zu halten, muss eine elektrische Spannung an das Heizelement angelegt werden. Diese Spannungsversorgung ist mit geeigneten Mitteln herzustellen. Ausserdem kommt es zu unterschiedlichen Leistungsanforderungen an das Heizelement. Diese ergeben sich aus der Aussentemperatur und der Geschwindigkeit des Fahrzeuges. Mit unterschiedlich hohen elektrischen Spannungen kann darauf Einfluss genommen werden. Die Berechnung der Leistung und die Bereitstellung der elektrischen Spannung übernimmt die Fahrzeugelektrik. Zusätzlich kann im Wischerblatt noch ein Temperaturfühler integriert werden. Dieser kann zu weiteren Temperaturregelungen verwendet werden. Um im Fehlerfall ein Überhitzen des Wischerblattes zu verhindern, kann eine Temperatursicherung eingebaut werden.Around to keep the wiper blade ice-free under the circumstances described an electrical voltage is applied to the heating element. These Voltage supply must be established by suitable means. Moreover There are different performance requirements for the heating element. These result from the outside temperature and the speed of the vehicle. With different levels of electrical voltage can be influenced. The calculation of the power and the provision of electrical voltage takes over the vehicle electrics. additionally can be integrated in the wiper blade still a temperature sensor. This can be used for further temperature control. To overheat in case of error To prevent the wiper blade, a thermal fuse to be built in.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass die Verkehrssicherheit erhöht wird.The particular advantages of the invention are that increases traffic safety becomes.
