Abstract

The electrical heating device in the door lock of a motor vehicle must be capable of being switched on from outside in order to thaw out the frozen door lock. Mechanical switch contacts permanently installed for this in the door lock or on the motor vehicle have the disadvantage that the heating device is switched on continuously as a result of an improper jamming of the switch contact and consequently the battery of the motor vehicle is drained. Switch contacts, in which a simple jamming is impossible, for example those which are actuated by a permanent magnet, or electronic switching devices have the disadvantage of a high technical outlay. To reduce the risk of an improper switch-on and to avoid a high technical outlay, the car key, by means of which an interrupted electrical feed line to the heating device is bridged, is used for switching on the heating device.

Description

Bezeichnung: Türgriff für Türen von KraftfahrzeugenDescription: Door handle for doors of motor vehicles

Beschreibung Türgriff für Türen von Kraftfahrzeugen Die Erfindung betrifft einen Türgriff zum Öffnen eines Türschlosses an der Tür eines Kraftfahrzeuges, dessen Türschloß mittels einer elektrischen Heizvorrichtung heizbar ist, die mindestens ein Heizelement und eine Schalteinrichtung aufweist. Description of door handle for doors of motor vehicles The invention relates to a door handle for opening a door lock on the door of a motor vehicle, whose door lock can be heated by means of an electrical heating device, the at least has a heating element and a switching device.

Schalter im herkömmlichen Sinne zum Einschalten der Heizvorrichtung sind bekannt und haben den nachteil, dass diese auf einfache Weise missbräuchlich blockierbar sind, was zum Entleeren der Spannungsquelle (Autobatterie) führt.Switch in the conventional sense for switching on the heating device are known and have the disadvantage that they can easily be misused can be blocked, which leads to the emptying of the voltage source (car battery).

Schalter wie Reedkontakte, welche nur mittels eines Hilremittels, e,B. eines Permanentmagnetes betätigt worden können, sind technisch und kostenmässig aufwendig.Switches such as reed contacts, which can only be e, B. a permanent magnet can be actuated, are technically and cost-effectively laborious.

Die vorliegende Erfindung hat sich zum Ziel gesetzt, bereits serienmässig an einem Autotürgriff vorhandene Metallteile als Schaltelement zu verwenden.The present invention has set itself the goal, already in series to use existing metal parts on a car door handle as a switching element.

Die Konstruktion ist hierbei so getroffen, dass ein isoliertes Metallteil des Türgriffes mit dem Heizelement elektrisch leitend verbunden wird. Durch Überbrücken auf ein zweites nicht isoliertes und mit Masse verbundenes Metallteil des Türgriffe wird der Heizstromkreis geschlossen.The construction is made in such a way that an isolated metal part the door handle is connected to the heating element in an electrically conductive manner. By bridging to a second non-insulated metal part of the door handle that is connected to ground the heating circuit is closed.
