Description

Die Erfindung betrifft einen Schlüssel, insbesondere zum Betätigen eines Lenk- oder Zündschlosses eines Kraftfahrzeugs. Solche Schlüssel weisen einen Schlüsselgriff auf, an dem ein Schlüsselschaft mit einem mechanisch codierten Schlüsselbart befestigt ist.The invention relates to a key, in particular for actuation a steering or ignition lock of a motor vehicle. Such keys have a key handle on the Key shaft with a mechanically coded key bit is attached.

Bei bekannten Schlüssein (DE 34 37 439 C2 oder DE 42 03 886 C2) ist der Schlüsselschaft über ein bewegliches Scharnier mit dem Schlüsselgriff verbunden. Wenn der Schlüssel ein Zündschlüssel eines Kraftfahrzeugs ist, der im Zündschloß steckt, so besteht bei einem Auffahrunfall die Gefahr, daß das Knie des Fahrers gegen den Zündschlüssel und dessen Schlüsselgriff stößt. Um dies zu vermeiden, wird bei den bekannten Schlüssein der Schlüsselgriff um 90° geschwenkt und verbleibt dort. In dieser Position wird die Gefahr einer Knieverletzung jedoch nur gering gemindert.With known keys (DE 34 37 439 C2 or DE 42 03 886 C2) is the key shaft via a movable hinge connected to the key handle. If the key is one The ignition key of a motor vehicle is in the ignition lock is stuck, there is a risk in a rear-end collision that the driver's knee against the ignition key and its Key handle bumps. To avoid this, the known The key handle is swiveled by 90 ° and stay there. In this position there is a danger of However, knee injury was only slightly reduced.

Das Problem der Erfindung ist es, einen Schlüssel zu schaffen, der Schutz vor Verletzungen bietet, wenn eine Person gegen den Schlüsselgriff stößt.The problem of the invention is to create a key protection from injury when a person is against pushes the key handle.

Dieses Problem wird erfindungsgemäß durch die Merkmale von Patentanspruch 1 gelöst. Dabei ist der Schlüsselschaft elastisch mittels einer Halterung mit dem Schlüsselgriff verbunden. Wenn eine Kraft auf den Schlüsselgriff einwirkt, so gibt der Schlüsselgriff in die betreffende Richtung nach.According to the invention, this problem is solved by the features of Claim 1 solved. The key shaft is elastic connected to the key handle by means of a holder. If there is a force on the key handle, there is the key handle in the relevant direction.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet. So ist es besonders vorteilhaft, wenn die Halterung eine Sollbruchstelle aufweist. Somit bricht diese Stelle, wenn der Druck auf den Schlüsselgriff zu groß wird. Der Krafteinwirkung auf den Schlüsselgriff kann ebenfalls gut nachgegeben werden, wenn die Halterung aus einem elastischen Material hergestellt ist. Des weiteren wird die Elastizität der Halterung des Schlüsselgriffs dadurch verbessert, daß die Halterung über federnde, S-förmige Verbindungsstege mit dem Schlüsselschaft verbunden ist. Somit kann der Schlüsselgriff in alle Richtungen nachgiebig bewegt werden.Advantageous embodiments of the invention are in the subclaims featured. So it’s particularly beneficial if the bracket has a predetermined breaking point. Consequently breaks this point when pressure is applied to the key handle gets big. The force acting on the key handle can also give way well if the bracket comes from a elastic material is made. Furthermore, the elasticity of the holder of the key handle improves that the bracket via resilient, S-shaped connecting webs connected to the key shaft. Consequently the key handle can be flexibly moved in all directions will.

Ein Schlüssel 1 (Figur 1), insbesondere zum Betätigen eines Lenk- oder Zündschlosses eines Kraftfahrzeugs weist einen Schlüsselgriff (im folgenden als Griff 2 bezeichnet) auf, an dem über einen Schlüsselschaft (im folgenden als Schaft 3 bezeichnet) ein Schlüsselbart (im folgenden als Bart 4 bezeichnet) mit einer mechanischen Codierung befestigt ist. Der Bart 4 und der Schaft 3 stecken dabei in einem Schlüsselloch 5 eines Schlosses 6.A key 1 (Figure 1), in particular for actuating a Steering or ignition lock of a motor vehicle has one Key handle (hereinafter referred to as handle 2) on via a key shaft (hereinafter referred to as shaft 3) a key bit (hereinafter referred to as beard 4) is fixed with a mechanical coding. The beard 4 and the shaft 3 are in a keyhole 5 one Castle 6.

Der Schaft 3 ist elastisch (federnd) mit Hilfe eines elastischen Befestigungsmittels (im folgenden als Halterung 7 bezeichnet) an dem Griff 2 befestigt (zur besseren Verständnis ist der Bereich des Schlüssels 1 um die Halterung 7 in den Figuren als Schnitt und nicht als Draufsicht dargestellt). Hierzu kann die Halterung 7 einerseits aus einem elastischen, nachgiebigen Material hergestellt sein und/oder andererseits durch seine Formgebung in Form von elastischen Verbindungsstegen 8 (hier S-förmig ausgebildet) federnd ausgebildet sein. Wenn beispielsweise eine axiale Kraft F1 (in der Figur 1 durch den Pfeil dargestellt; Kraftrichtung parallel zur Achse 3' des Schafts 3 und zum Schloß 6 hin gerichtet) einwirkt, so wird der Griff 2 aufgrund der Elastizität der Halterung 7 gegen das Schloß 6 gedrückt.The shaft 3 is fastened elastically (resiliently) to the handle 2 with the aid of an elastic fastening means (hereinafter referred to as holder 7) (for better understanding, the area of the key 1 around the holder 7 is shown in the figures as a section and not as a plan view ). For this purpose, the holder 7 can be made on the one hand from an elastic, resilient material and / or on the other hand can be designed to be resilient due to its shape in the form of elastic connecting webs 8 (here S-shaped). If, for example, an axial force F 1 (represented by the arrow in FIG. 1; direction of force directed parallel to the axis 3 ′ of the shaft 3 and towards the lock 6) acts, the handle 2 becomes against the lock 6 due to the elasticity of the holder 7 pressed.

Eine solche axiale Kraft F1 kann beispielsweise dann entstehen, wenn eine Person unbeabsichtigterweise gegen den Griff 2 drückt oder anstößt. Da der Griff 2 über die Halterung 7 federnd mit dem Schaft 3 verbunden ist, wird ein Verletzungsrisiko der Person gemindert.Such an axial force F 1 can arise, for example, when a person inadvertently presses or pushes the handle 2. Since the handle 2 is resiliently connected to the shaft 3 via the holder 7, a risk of injury to the person is reduced.

Statt der axialen Kraft F1 kann auch eine seitliche Kraft F2 (Figur 2; siehe Pfeil) an einer von dem Schloß 6 abgewandten Seite des Griffs 2 angreifen. Infolgedessen wird der Griff 2 um einen Verbiegungswinkel α gegenüber der Achse 3' des Schaftes 3 verbogen (ursprüngliche Lage des Griffs 2 ist in der Figur 2 gestrichelt dargestellt), da die Halterung 7 durch ihre individuelle Formgebung oder durch das elastische Material, aus dem die Halterung 7 hergestellt ist, federnd nachgiebig wirkt. Die Größe des Verbiegungswinkels α hängt dabei von der Größe, von der Richtung und von dem Angriffspunkt der Kraft F1 oder F2 ab.Instead of the axial force F 1 , a lateral force F 2 (FIG. 2; see arrow) can also act on a side of the handle 2 facing away from the lock 6. As a result, the handle 2 is bent by a bending angle α with respect to the axis 3 'of the shaft 3 (original position of the handle 2 is shown in dashed lines in FIG. 2), since the holder 7 by its individual shape or by the elastic material from which the Bracket 7 is made, resilient acts. The size of the bending angle α depends on the size, the direction and the point of application of the force F 1 or F 2 .

Das Schloß 6 seinerseits kann so ausgebildet sein, daß der Griff 2 ab einem bestimmten Verbiegungswinkel α gegen das Gehäuse des Schlosses 6 anstößt. Falls der Griff 2 zusätzlich noch eine nicht dargestellte, elastische Kappe aufweist, so wird der Stoß zusätzlich gedämpft. Je nach Härte und Elastizität des verwendeten Materials für die Halterung 7 kann verhindert werden, daß der Griff 2 von dem Schaft 3 abbricht.The lock 6 in turn can be designed so that the Handle 2 from a certain bending angle α against the housing of the castle 6 abuts. If the handle 2 is additional still has an elastic cap, not shown, so the shock is additionally dampened. Depending on the hardness and elasticity of the material used for the holder 7 can be prevented be that the handle 2 breaks off from the shaft 3.

Die Halterung 7 darf jedoch nicht zu weichelastisch sein, damit der Schaft 3 im Schloß 6 per Hand noch gedreht werden kann. Sie darf aber auch nicht zu unnachgiebig sein, damit auch hohe Kräfte und Stöße, beispielsweise bei Knieaufprall auf den Griff 2, durch die elastische Halterung 7 aufgenommen werden.The bracket 7 must not be too soft, so that the shaft 3 in the lock 6 can still be turned by hand can. But you mustn't be too adamant about it either also high forces and shocks, for example in the event of a knee impact on the handle 2, taken up by the elastic holder 7 will.

Werden die Kräfte jedoch zu groß, so bricht die Halterung 7. Falls die Halterung 7 Sollbruchstellen 9 aufweist, so kann die Größe der Kraft F1 oder F2, bei der Griff 2 abbrechen soll, und der genaue Ort des Bruchs festgelegt werden. Sollbruchstellen 9 sind Verjüngungen im Material, die beispielsweise durch Einkerbungen erzeugt werden. Sollbruchstellen 9 können auch durch ein Material erzeugt werden, das nur in einem eng begrenzten Bereich vorhanden ist und das wegen seiner geringeren Elastizitätsgrenze als das sonstige Material des Griffs 2 für eine solche Anwendung in Frage kommt (oberhalb der Elastizitätsgrenze findet eine plastische Verformung statt, d.h. bei zu großer Krafteinwirkung zerreißt oder bricht das Material).If the forces become too great, however, the holder 7 breaks. If the holder 7 has predetermined breaking points 9, the size of the force F 1 or F 2 at which handle 2 is to break off and the exact location of the break can be determined. Predetermined breaking points 9 are tapers in the material, which are produced, for example, by indentations. Predetermined breaking points 9 can also be produced by a material which is only present in a narrowly limited area and which, because of its lower elastic limit than the other material of the handle 2, is suitable for such an application (above the elastic limit there is a plastic deformation, ie if the force is too great, the material tears or breaks).

Falls sich das Schloß 6 - wie in den Figuren 1 und 2 dargestellt - in einer Vertiefung oder Nische befindet, so wird dadurch erreicht, daß der Griff 2 auch bei sehr großer Krafteinwirkung nicht bricht, da der Griff 2 dann an die Seitenwände der Nische anstößt.If the lock 6 - as shown in Figures 1 and 2 - is located in a recess or niche achieved in that the handle 2 even with very great force does not break, since the handle 2 then on the side walls the niche bumps.

Die Sollbruchstellen 9 können in der Nähe des Schafts 3 angeordnet sein. Allerdings ist dann ein Drehen des Schlüssels 1 im Schloß 6 kaum noch möglich, wenn der Griff 2 abgebrochen ist. Aus diesem Grunde ist es vorteilhaft, wenn die Sollbruchstellen 9 weiter entfernt von dem Schaft 3 angeordnet sind. Somit verbleiben noch genügend lange Hebel, mit denen ein genügend großes Drehmoment auf den Schaft 3 ausgeübt werden kann, damit dieser im Schloß 6 verdreht werden kann.The predetermined breaking points 9 can be arranged in the vicinity of the shaft 3 be. However, turning the key 1 hardly possible in lock 6 when handle 2 broke off is. For this reason, it is advantageous if the predetermined breaking points 9 arranged further away from the shaft 3 are. This leaves enough leverage with which a sufficiently large torque can be exerted on the shaft 3 can so that it can be rotated in lock 6.

Der Schlüssel 1 kann zum mechanischen Betätigen oder auch zum elektrischen Betätigen des Schlosses 6 verwendet werden. Zum elektrischen Betätigen des Schlosses 6 weist der Schlüssel 1 eine in einem Griffgehäuse 10 (Figur 3) angeordnete Sende- und/oder Empfangseinheit auf, durch die codierte Signale drahtlos (per Infrarot oder Funk) ausgesendet bzw. empfangen werden. Zum Senden von Signalen weist das Griffgehäuse 10 Tasten 11 auf, bei deren Betätigung die codierten Signale erzeugt und anschließend über eine Sende- und Empfangsantenne ausgesendet werden.The key 1 can be used for mechanical actuation or electrical actuation of the lock 6 can be used. To the the key 1 is electrically actuated by the lock 6 a transmitting and / or arranged in a handle housing 10 (Figure 3) Receiving unit through which coded signals transmitted or received wirelessly (via infrared or radio) will. The handle housing has 10 buttons for sending signals 11 on, the coded signals generated when actuated and then via a transmitting and receiving antenna be sent out.

Das Griffgehäuse 10 wird vorteilhafterweise in einen Aufnahmekörper 12 eingesteckt und dort durch Einrasten befestigt. Hierzu weist der Aufnahmekörper 12 und das Griffgehäuse 10 Rastnasen und Rastnuten auf, die der Übersichtlichkeit halber nicht in den Figuren dargestellt sind. Der Aufnahmekörper 12 weist die elastische Halterung 7 auf, an der der Schaft 3 befestigt ist. Somit wird der Griff 2 gegenüber dem Schaft 3 federnd gehalten.The handle housing 10 is advantageously in a receiving body 12 inserted and fastened there by snapping. For this purpose, the receiving body 12 and the handle housing 10 Lugs and notches on, for the sake of clarity are not shown in the figures. The receiving body 12 has the elastic holder 7 to which the shaft 3 is attached is. The handle 2 is thus opposite the shaft 3 kept resilient.

Die Halterung 7 kann Nuten 13 (Figuren 3 oder 4) aufweisen, durch die ein elastisches Verbiegen des Griffs 2 gegenüber dem Schaft 3 erleichtert wird. Die Nuten 13 können darüber hinaus derart tief in das Material hineinragen, daß eine Sollbruchstelle 9 entsteht. Falls die Kraft F1 oder F2 auf den Griff 2 zu groß wird, so bricht der Griff 2 im Bereich der Nuten 13 ab. Die Größe der Kraft F1 oder F2, bei der der Griff 2 abbricht, hängt dabei von dem verwendeten Material und der Formgebung der Halterung 7 ab. Kleine Kräfte wirken sich hingegen nur wenig aus, da solche Stöße wegen der Elastizität der Halterung 7 aufgefangen werden, so daß sich der Griff 2 nur kurzzeitig gegenüber der Achse 3' des Schafts 3 verbiegt und anschließend wieder in seine ursprüngliche Lage zurückkehrt.The holder 7 can have grooves 13 (FIGS. 3 or 4), by means of which an elastic bending of the handle 2 relative to the shaft 3 is facilitated. The grooves 13 can also protrude so deeply into the material that a predetermined breaking point 9 is created. If the force F 1 or F 2 on the handle 2 becomes too great, the handle 2 breaks off in the area of the grooves 13. The magnitude of the force F 1 or F 2 at which the handle 2 breaks off depends on the material used and the shape of the holder 7. Small forces, on the other hand, have little effect, since such shocks are absorbed because of the elasticity of the holder 7, so that the handle 2 bends only briefly with respect to the axis 3 'of the shaft 3 and then returns to its original position.

Die Halterung 7 ist vorzugsweise aus einem elastischen Material, wie einem - zum Teil mit Glasfaser verstärkten - Kunststoff (z.B. Polyamid), hergestellt, so daß der Griff 2 gegenüber dem Schaft 3 elastisch ist, wenn eine Kraft F1 oder F2 an dem Griff 2 angreift. Die Halterung 7 wirkt dadurch wie eine Feder mit einer von Material und Formgebung abhängigen Federkonstanten mit einem begrenzten Ausschlag.The bracket 7 is preferably made of an elastic material, such as a - partially reinforced with glass fiber - plastic (eg polyamide), so that the handle 2 is elastic relative to the shaft 3 when a force F 1 or F 2 on the handle 2 attacks. The holder 7 thus acts like a spring with a spring constant depending on the material and shape, with a limited deflection.

Die Nuten 13, durch die das Verbiegen des Griffs 2 ebenfalls ermöglicht wird, können auf der Innenseite des Griffs 2 (wie in Figur 3 dargestellt) oder auch auf der Außenseite (wie in Figur 4 dargestellt) angebracht sein. Es können auch mehrere Nuten 13 in dem Griff 2 angeordnet sein (vgl. Figuren 1 und 2).The grooves 13 through which the handle 2 is also bent enabled, can on the inside of the handle 2 (like shown in Figure 3) or on the outside (as in Figure 4 shown) be attached. You can also have several Grooves 13 may be arranged in the handle 2 (see FIGS. 1 and 2).

Das von dem Aufnahmekörper 12 trennbare Griffgehäuse 10 hat den Vorteil, daß der Aufnahmekörper 12 universell für viele Schlösser verwendet werden kann. Das Griffgehäuse 10 mit der Sende- und Empfangseinheit braucht erst am Ende der Fertigung eines Kraftfahrzeugs oder erst beim Kunden zusammen mit dem Aufnahmekörper 12 zu einer Einheit zusammengefügt werden. Vorher ist das Starten des Kraftfahrzeugs mit dem Aufnahmekörper 12 möglich, der hierzu genügend Angriffsfläche bietet. Denn mit dem in den Figuren 3 und 4 dargestellten etwa u-förmigen Aufnahmekörper 12 kann bereits ein mechanisches Betätigen (Drehen des Schlüssels 1) des Schlosses 6 vorgenommen werden, wenn ein Benutzer an den beiden Schenkeln des Aufnahmekörpers 12 angreift. Has the handle housing 10 separable from the receiving body 12 the advantage that the receiving body 12 is universal for many Locks can be used. The handle housing 10 with the The sending and receiving unit is only needed at the end of production a motor vehicle or only at the customer together with the Receiving body 12 can be assembled into a unit. Before that is starting the motor vehicle with the receiving body 12 possible, which offers enough surface for this. Because with the approximately U-shaped shown in Figures 3 and 4 Receiving body 12 can already be operated mechanically (Turn the key 1) of the lock 6 made be when a user on the two legs of the receiving body 12 attacks.

Der Schlüssel 1 in der dargestellten Form ist vorzugsweise als Schlüssel 1 für ein Lenk- oder Zündschloß geeignet.
