Abstract
Description
Die Erfindung betrifft ein Gurtschloss für ein Sicherheitsgurtsystem zur Verriegelung einer Gurtzunge mit einem Riegelmechanismus und einem den Riegelmechanismus in Schließrichtung belastenden Federelement.The The invention relates to a buckle for a safety belt system for locking a belt tongue with a locking mechanism and a locking element loading the locking mechanism in the closing direction spring element.

Da der Riegelmechanismus im Allgemeinen bei Gurtschlössern insgesamt Lasttragend ausgebildet sein muss und daher bevorzugt aus metallischen Werkstoffen gebildet ist, können bei der Schließbewegung des Riegelmechanismus unerwünschte hart klingende Geräusche entstehen. Dies ist insbesondere dann der Fall, wenn nur eine Feder verwendet wird und die Schließbewegung wie oben beschrieben abrupt abgestoppt wird, so dass die Teile des Riegelmechanismus mit einem hohen Impuls aufeinanderschlagen.There the locking mechanism generally in buckles in total Load-bearing must be formed and therefore preferably made of metallic materials is formed, can during the closing movement the locking mechanism undesirable hard-sounding noises arise. This is especially the case when only one spring is used and the closing movement abruptly stopped as described above, so that the parts of the Bolt mechanism with a high pulse beat each other.
Aufgrund der erhöhten Anforderungen in modernen Kraftfahrzeugen an die Akustikverhältnisse im Innenraum ist es jedoch wünschenswert, die entstehenden Geräusche beim Verriegeln des Gurtschlosses soweit wie möglich zu reduzieren.by virtue of the heightened Requirements in modern motor vehicles to the acoustic conditions in the Interior, however, it is desirable the resulting noise when locking the buckle as much as possible to reduce.

Aufgabe der Erfindung ist es daher, ein Gurtschloss mit einer möglichst geringen Geräuschentwicklung beim Verriegeln des Riegelmechanismus zu schaffen.task The invention is therefore a buckle with a possible low noise to create when locking the latch mechanism.
Die Lösung der Aufgabe erfolgt erfindungsgemäß durch ein Gurtschloss mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterentwicklungen sind in den Unteransprüchen angegeben.The solution The object is achieved by a buckle with the features of claim 1. Advantageous developments are in the subclaims specified.
Gemäß Anspruch 1 wird vorgeschlagen, dass ein gegen die Schließrichtung des Riegelmechanismus wirkendes Dämpfungselement vorgesehen ist. Damit wird die Schließbewegung bewusst gedämpft, so dass die Verzögerung des Riegelmechanismus gegen Ende der Schließbewegung und die damit einhergehende Geräuschentwicklung entsprechend vermindert ist.According to claim 1 it is proposed that an against the closing direction of the latch mechanism acting damping element is provided. Thus, the closing movement is deliberately dampened, so that the delay the locking mechanism towards the end of the closing movement and the associated noise is reduced accordingly.
Eine einfache Ausführung des Dämpfungselementes besteht darin, dass dieses durch ein zweites Federelement gebildet ist, und die von dem zweiten Federelement auf den Riegelmechanismus ausgeübte Federkraft kleiner als die von dem ersten Federelement auf den Riegelmechanismus ausgeübte Federkraft ist. Durch die Auslegung der Federkräfte wird sichergestellt, dass der Verriegelungsvorgang nicht durch das Dämpfungselement gestört werden kann.A simple execution of the damping element is that this formed by a second spring element is, and that of the second spring element on the locking mechanism practiced Spring force smaller than that of the first spring element on the locking mechanism applied spring force is. The design of the spring forces ensures that the locking process can not be disturbed by the damping element.
Das zweite Federelement kann bevorzugt aus einer Blattfeder gebildet sein, die kostengünstig als Stanzteil hergestellt werden kann und auch in den beengten Bauraumverhältnissen des Gurtschlosses einfach angeordnet werden kann.The second spring element may preferably be formed from a leaf spring be that cost-effective as Stamped part can be produced and in the cramped space conditions the buckle can be easily arranged.
Der Aufbau der Konstruktion vereinfacht sich weiter dadurch, indem die Blattfeder mit einem Ende fest an dem Gurtschloss eingespannt ist und mit einem freien Ende an dem Riegelmechanismus anliegt.Of the Construction of the structure is further simplified by the fact that the Leaf spring is firmly clamped at one end to the buckle and abuts the latch mechanism with a free end.
Es wird weiter vorgeschlagen, dass die Blattfeder wenigstens zwei an dem Riegelmechanismus anliegende Federarme aufweist. Hierdurch wird zum einen sichergestellt, dass auch bei dem Brechen einer der Federarme die Funktion gewährleistet wird und zum anderen die Federkraft beidseitig verteilt wird, so dass die Federbelastung nicht zu einem Verkippen des Riegelmechanismus führen kann.It is further proposed that the leaf spring at least two Having the locking mechanism fitting spring arms. This will on the one hand ensures that even when breaking one of the spring arms Ensures the function and on the other hand, the spring force is distributed on both sides, so that the spring load does not cause a tilting of the latch mechanism to lead can.
Zusätzlich kann die Blattfeder einen die Gurtzunge im eingeschobenen Zustand in Auswurfrichtung belastenden Federarm aufweisen. Hierdurch wird zusätzlich die Auswurfbewegung der Gurtzunge unterstützt.In addition, the leaf spring having a belt tongue in the inserted state loading in the direction of ejection spring arm. hereby In addition, the ejection movement of the belt tongue is supported.
Ein besonders einfacher konstruktiver Aufbau ergibt sich dadurch, dass das Gurtschloss einen Einschubkanal für die Gurtzunge aufweist, der Riegelmechanismus einen bei in den Einschubkanal eingeschobener Gurtzunge in eine Ausnehmung der Gurtzunge eingreifenden Riegel aufweist und das Dämpfungselement zwischen dem Riegel und dem Einschubkanal angeordnet ist, wobei der Riegel vorzugsweise schwenkbar an dem Gurtschloss angeordnet ist.One Particularly simple structural design results from the fact that the buckle has a slot for the belt tongue, the Latch mechanism one inserted into the insertion channel Belt tongue in a recess of the belt tongue engaging latch and the damping element is arranged between the latch and the insertion channel, wherein the latch preferably pivotally mounted on the buckle is.
Die Blattfeder ist dann bevorzugt im Bereich des Schwenklagers des Riegels fest eingespannt und liegt mit ihrem freien Ende an der dem Einschubkanal zugewandten Seite an dem Riegel an.The Leaf spring is then preferred in the region of the pivot bearing of the bolt firmly clamped and lies with its free end to the insertion channel facing side of the latch.
Ferner kann das Gurtschloss zwischen dem Einspannbereich der Blattfeder und dem Federarm eine die Blattfeder an der von dem Riegel abgewandten Seite unterstützende Anlagefläche aufweisen, so dass die Federbewegung nicht zu einem Knicken der Blattfeder führen kann.Further can the buckle between the clamping area of the leaf spring and the spring arm, a leaf spring on the side facing away from the bolt Side supporting contact surface so that the spring movement does not cause the leaf spring to buckle to lead can.
Es hat sich durch Versuche herausgestellt, dass die Federarme zu dem Einspannbereich einen Winkel von 140–170 Grad einschließen sollen. Durch die Abwinkelung der Federarme wird den Federarmen eine Eigensteifigkeit eingeprägt, wodurch letztlich die gewünschten Federkräfte auch unter Berücksichtigung der zur Verfügung stehenden engen Bauraumverhältnisse einfach erzeugt werden können.It has been found by experiments that the spring arms to the Clamping area to include an angle of 140-170 degrees. By bending the spring arms, the spring arms an inherent rigidity imprinted, ultimately the desired ones spring forces also considering the available standing tight space conditions can be easily generated.
Nachfolgend wird die Erfindung zum besseren Verständnis anhand eines bevorzugten Ausführungsbeispieles näher erläutert. In den Figuren ist im Einzelnen zu erkennen:following The invention will be better understood by reference to a preferred embodiment explained in more detail. In The figures show in detail:
