Description

'1Sicherheitslenkung für Kraftwagen Die Erfindung betrifft eine Sicherheitsienkung für Kraftsfagen, mit einem Lenkhandrad mit einer - in Geradeausfahrt-Stellung der Lenkung gesehen - quer verlaufenden Speiche und einem zwischen dem oberen Ende der Lenkwelle und dem Lenkhandrad angeordneten, plastisch verformbaren Deformationsglied.1Safety steering for motor vehicles The invention relates to a safety steering for Kraftsfagen, with a steering handwheel with a - in the straight-ahead position of the Steering seen - transverse spoke and one between the top of the Steering shaft and the steering handwheel arranged, plastically deformable deformation member.

Disher vorgeschlagene, sicherheitsgerecht gestaltete Lenkhandrider wiesen ganz allgemein den Nachteil auf, daß die Sicht des Fahrers insbesondere auf die Instrumententafel ziemlich stark eingeschränkt war. Andererseits war es so, daß Lenkungsanordnungen, die dem Fahrer eine ausreichende Sicht auf die Instrumente boten, wesentliche Mangel hinsichtlich der inneren Sicherheit des Fahrzeugs aufwiesen.This proposed, safety-oriented steering handrider generally had the disadvantage that the driver's vision in particular the instrument panel was quite restricted. On the other hand it was like that that steering arrangements that give the driver an adequate view of the instruments offered, had significant deficiencies in terms of the internal security of the vehicle.

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine Sicherheitslenkung für Kraftwagen zu schaffen, die dem Fahrer bei durcll einen Unfall verursachtem Aufprall auf das Lenkhandrad optimale Sicherheitsbedingungen bietet und die dem Fahrer andererseits eine völlig unbehinderte Sichtauf die Instrumententafel des Fahrzeugs gestattet.The present invention was therefore based on the object of addressing these disadvantages to avoid and to create a safety steering system for the driver optimal safety conditions in the event of an impact on the steering wheel caused by an accident and on the other hand the driver a completely unobstructed view of the instrument panel of the vehicle.

Weiterhin soll durch die vorliegende Erfindung ein Lenlchandrad einer Sicherheitslen1ung geschaffen werden1 dessen unteres Teil eine große, formstabile Fläche fiir den Aufprall der Brustpartie des Fahrers und dessen oberes Teil einen biegeweichen r2ereich für den Kopfaufprall bietet.Furthermore, the present invention is intended to be a Lenlchandrad Safety system is created1 whose lower part is a large, dimensionally stable Surface for the impact between the driver's chest and the driver's upper part flexible area for head impact.

Diese Aufgaben werden erfindungsgemäß dadurch gelöst, daß die obere Kontur der quer verlaufenden Speiche in an sich bekannter Weise unterhalb des Mittelpunktes des Lenkradkranzes liegt und daß die Nittellängsachse des Deformationsgliedes in Geradeausfallrt-Stellung der Lenkung wenigstens annähernd horizontal verläuft.These objects are achieved according to the invention in that the upper Contour of the transverse spoke in a manner known per se below the center point of the steering wheel rim and that the central longitudinal axis of the deformation member in Geradeausfallrt position of the steering is at least approximately horizontal.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. In der Zeichnung zeigen Fig. 1 einen vertikalen Längsschnitt durch eine erfindungsgemäße Lenkungsanordnung, und Fig. 2 eine Ansicht des dabei verwendeten Lenichandrades.The object of the invention is to be based on one in the Drawing illustrated embodiment will be explained in more detail. In the drawing 1 shows a vertical longitudinal section through a steering arrangement according to the invention, and FIG. 2 is a view of the Lenichand wheel used in this case.

Bei der in Fig.1 dargestellten Sicherheitslenkung ist zwischen dem oberen Ende der Lenkwelle t und dem Lenkhandrad 2 ein wellrohrförmig ausgebildetes Deformationsglied 3 angeordnet, dessen Mittellängsachse in Geradeausfahrt-Stellung der Lenlcung - in der Zeichnung dargestellt - horizontal verläuft. Diese Anordnung bietet den Vorteil, daß beim Aufprall des Fahrers auf das Lenkhandrad i das Deformationsglied 3 in Richtung seiner Mittellängsachse belastet wird, wodurch eine optimale Verformung des Deformationsgliedes 3 ohne seitliches Ausknicken erreicht wird.In the safety steering shown in Figure 1 is between the upper end of the steering shaft t and the steering handwheel 2 a corrugated tube-shaped Deformation member 3 is arranged, its central longitudinal axis in the straight-ahead position the steering - shown in the drawing - runs horizontally. This arrangement has the advantage that the deformation member when the driver impacts the steering handwheel i 3 is loaded in the direction of its central longitudinal axis, whereby an optimal deformation of the deformation member 3 is achieved without lateral buckling.

Das in Fig.2 dargestellte Lenkhandrad 2 weist eine gestaltfeste breite, quer verlaufende Speiche 4 auf, deren obere Kontur 5 unterhalb des Mittelpunkt es des Lenkradkranzes 6 verläuft. Im unteren Teil i des dargestellten Lenichandrades 2 ist mit unterbrochenen Linien 7 eine mögliche Variante der Speichenausbildung dargestellt, durch die sich zusätzlich eine vertikal verlaufende Speiche 8 ergeben lmrde.The steering handwheel 2 shown in Figure 2 has a solid shape, transverse spoke 4, the upper Contour 5 below the The center point of the steering wheel rim 6 runs. In the lower part i of the illustrated Lenichandrades 2 with broken lines 7 is a possible variant of the spoke design shown, which also result in a vertically extending spoke 8 tired.
