Description

Bezeichnung: t'Elektrisch beheizter AutoaußenspiegelttDesignation: t'Electrically heated car exterior mirrors

Beschreibung: Die Erfindung bezieht sich auf einen elektrisch beheizten Autoaußenspiegel für Kraftfahrzeuge. Der Autoaußenspiegel hat die Aufgabe, dem fahrer Ohne eine Kopfwendung die Verkehrssituation hinter und neben dem Auto sichtbar zu machen. Der richtig eingestellte Autoaußenspiegel erfüllt diese Aufgabe trotz seiner Kleinen Fläche. Nur in der kalten Jahreszeit überzieht sich der Autoaußenspiegel gern mit Raureif, Eis oder er ist zugeschnait und in der warmen Jahreszeit beschlägt er bei einem Regenguß oder hängt voller Regentropfen und versagt somit in seiner zueedachten Funktion. Es ist bekannt, daß manche Autoaußenspiegel einen tiefen Rand besitzen und somit wenigstens den Regen abhalten.Description: The invention relates to an electrically heated Exterior car mirrors for automobiles. The task of the exterior mirror is the driver You can see the traffic situation behind and next to the car without turning your head do. The properly adjusted car exterior mirror fulfills this task in spite of it Small area. The car exterior mirror is only covered in the cold season like with hoar frost, ice or it is cut up and steamed up in the warm season he in a downpour or hangs full of raindrops and thus fails in his intended function. It is known that some car exterior mirrors have a deep rim own and thus at least keep the rain off.

Bei ßeochlag mit Eis, Schnee, Reif oder Regen der Scheibe ist man bis jetzt gezwungen die Spiegelscheibe mechanisch zu reinigen, Patente für beheizte Autoaußenspieel, sei es nun durch eingebaute Wärmebirnen oder durch Infrarotbestrahlung von außen, scheiterten wohl bis jetzt an der ggewerblichen Verwertung durch den hohen Fertigungsaufwand und die Störanfälligkeit. Die Aufgabe wird erfindungsgemäß dadurch gelöst, das eine auf der Spiegelrückseite direkt aufgeklebte dünne Schicht (a) mit einem bestimmten elektrischen Widerstand beim durchfließen eines elektrischen Stois sich erwärmt und die Wärme unmittelbar von dieser Widerstandsschicht auf das Spiegelglas (b) durch Wärmeleitung übergeht und dadurch Wasser in den verschiedensten Zuständen schnell vom Spiegelglas (b) beseitigt.You are in the event of flooding with ice, snow, frost or rain on the windshield until now forced to clean the mirror pane mechanically, patents for heated ones Car exterior mirrors, be it through built-in heat bulbs or infrared radiation from outside, have probably failed until now due to commercial exploitation by the high manufacturing costs and susceptibility to failure. The object is according to the invention solved by having a thin layer glued directly onto the back of the mirror (a) with a certain electrical resistance when flowing through an electrical Stois heats up and the heat is transferred directly from this resistive layer to the Mirror glass (b) passes through heat conduction and thereby water in the most diverse Conditions quickly eliminated from the mirror glass (b).
