Abstract

The heatable motor vehicle steering wheel is heated by flexible heating wires (1) enveloped by a special synthetic material (2) and connected via a relay. The wires enclose the entire steering wheel and the wire ends lead from the center of the wheel and back to the center after passing around the entire wheel.

Description

BeschreibungDescription

Heizbares KraftfahrzeuglenkradHeated vehicle steering wheel

Herkömmliche Kraftfahrzeuglenkräder weisen ein rundes Metallgerüst, das von Kunststoff (Schaumstoff) umhüllt ist, auf.Conventional car steering wheels have a round metal frame covered with plastic (foam).

Diese herkömmlichen Lenkräder sind entsprechend der Temperatur im Auto besonders im Winter sehr kalt. Es dauert sehr lange, bis die Oberfläche des Lenkrades eine für die menschliche Hand angenehme Temperatur erreicht. Abgesehen von dem Unbehagen, dass man beim Festhalten eines kalten Lenkrades verspürt, wird das Fahrvermögen dadurch negativ beeinflusst.These conventional steering wheels are very cold, especially in winter, compared to the temperature in the car. It takes a long time for the surface of the steering wheel to reach a temperature that is comfortable for the human hand. Apart from the discomfort that one feels when holding a cold steering wheel, this negatively affects the driving ability.

Der im Schutzbereich angegebenen Erfindung liegt das Problem zugrunde, ein Lenkrad zu schaffen, dessen Oberfläche unabhängig von der Umgebungstemperatur warm wird.The invention specified in the scope of protection is based on the problem of creating a steering wheel whose surface becomes warm regardless of the ambient temperature.

Dieses Problem wird mit den im Schutzbereich angegebenen Merkmalen (von einem Spezialkunststoff umhüllte, flexible Heizdrähte, die das gesamte Lenkrad umschließen und über ein Relais zugeschaltet werden) gelöst.This problem is solved with the features specified in the protection area (flexible heating wires covered in a special plastic that enclose the entire steering wheel and are switched on via a relay).

Durch die Zuschaltung über ein Relais, wird die zugeführte Stromleistung so reguliert, dass der Spezialkunststoff warm wird und die Wärme an die Oberfläche des Lenkrades so abgibt, dass die Temperatur der Oberfläche fur die Hände des Fahrers angenehm ist, aber nie so hoch ist, dass sich der Aggregatzustand der Lenkradoberfläche und ebenso der des Spezialkunststoffes zu extrem verändert.By switching on via a relay, the supplied power is regulated so that the special plastic becomes warm and transfers the heat to the surface of the steering wheel in such a way that the temperature of the surface is comfortable for the driver's hands, but is never so high that the state of the steering wheel surface and also that of the special plastic changes too drastically.

Mit der Erfindung wird erreicht, dass die Oberfläche des Lenkrades unabhängig von der Umgebungstemperatur warm wird. Das bedeutet, dass der Fahrer des Kraftfahrzeuges beim Führen seines Fahrzeugs nicht durch die Kälte der Oberfläche des Lenkrades beeinträchtigt wird. Dadurch ist sein Fahrvermögen sehr viel besser als beim Fahren mit kaltem Lenkrad, was nicht nur seinem eigenen Wohlbefinden dient, sondern auch zur Sicherheit aller Verkehrsteilnehmer im Straßenverkehr beiträgt.The invention ensures that the surface of the steering wheel becomes warm regardless of the ambient temperature. This means that the driver of the motor vehicle is not affected by the coldness of the surface of the steering wheel when driving his vehicle. This means that his driving ability is much better than when driving with a cold steering wheel, which not only benefits his own well-being, but also contributes to the safety of all road users.

Ein Ausfuhrungsbeispiel der Erfindung wird anhand der Figuren 1 und 2 und den Querschnittdarstellungen A-A und B-B erläutert.An embodiment of the invention is explained with reference to Figures 1 and 2 and the cross-sectional views A-A and B-B.

Fig. 1 ist eine Schnittdarstellung des Lenkrades von vorne. Sie zeigt, wie die flexiblen Heizdrähte in der Mitte des Lenkrades angeschlossen werden und wie sie um das Lenkrad laufen.Fig. 1 is a front cross-sectional view of the steering wheel. It shows how the flexible heating wires are connected in the center of the steering wheel and how they run around the steering wheel.

Fig. 2 ist eine Schnittdarstellung des Lenkrades von hinten. Sie zeigt die Fig.l um einen Winkel von 180° nach unten gekippt. Hier ist zu sehen, wie die Heizdrähte zurück zur Anschlussstelle gelangen, nachdem sie das gesamte Lenkrad umschlossen haben.Fig. 2 is a sectional view of the steering wheel from behind. It shows the fig. 1 tilted downwards by an angle of 180°. Here you can see how the heating wires return to the connection point after they have surrounded the entire steering wheel.

Die Querschnittdarstellung A-A zeigt den Verlauf des Spezialkunststoffes mit den Heizdrähten im inneren des Lenkrades.The cross-section A-A shows the course of the special plastic with the heating wires inside the steering wheel.

Die Querschnittdarstellung B-B zeigt, wie die Heizdrähte in der Mitte des Lenkrades angeschlossen sind und wie sie nach einer kompletten Umdrehung um das gesamte Lenkrad wieder diese Anschlussstelle erreichen.The cross-section B-B shows how the heating wires are connected in the middle of the steering wheel and how they reach this connection point again after a complete rotation around the entire steering wheel.

In den Figuren 1 und 2 und den Querschnittdarstellungen A-A und B-B sind die Heizdrähte mit der Zahl 1 gekennzeichnet. Der spezielle Kunststoff, der diese Heizdrähte umschließt ist mit 2 gekennzeichnet. Der Kunststoff (Schaumstoff) ist mit 3, das Metallgerüst des Lenkrades ist mit 4 gekennzeichnet.In Figures 1 and 2 and the cross-sectional views A-A and B-B, the heating wires are marked with the number 1. The special plastic that encloses these heating wires is marked with 2. The plastic (foam) is marked with 3, the metal frame of the steering wheel is marked with 4.
