Definitions

  • the invention relates to a belt buckle for a belt system with a lap belt and two shoulder belts, wherein one end of the lap belt is attached to a metal frame bordered by the lock housing and the other end of the lap belt is connected to a metallic lock tongue which can be plugged into the lock housing and can be locked to the frame via a lock that can be released manually by means of a button, while end pieces are provided for fastening the shoulder strap ends, which are plugged in alignment on a common holding part when the buckle is in the closed position.

Description

Die Erfindung betrifft ein Gurtschloß für ein Gurtsystem mit einem Beckengurt und zwei Schultergurten, wobei das eine Ende des Beckengurtes an einem vom Schloßgehäuse eingefaßten, metallischen Rahmen befestigt ist und das andere Ende des Beckengurtes mit einer metallischen Schloßzunge verbunden ist, die in das Schloßgehäuse steckbar und mit dem Rahmen über eine von Hand mittels einer Taste lösbare Sperre verrastbar ist, während zur Befestigung der Schultergurtenden Endstücke vorgesehen sind, die bei in Schließstellung befindlichem Gurtschloß auf einem gemeinsamen Halteteil fluchtend aufgesteckt sind.The invention relates to a belt buckle for a belt system with a lap belt and two shoulder belts, wherein one end of the lap belt is attached to a metal frame bordered by the lock housing and the other end of the lap belt is connected to a metallic lock tongue which can be plugged into the lock housing and can be locked to the frame via a lock that can be released manually by means of a button, while end pieces are provided for fastening the shoulder strap ends, which are plugged in alignment on a common holding part when the buckle is in the closed position.

Ein bekanntes Gurtschloß dieser Art ermöglicht es, daß die Gurtband-Endstücke auf ein gemeinsames Halteteil aufgesteckt werden, wobei diese Endstücke nach Verrastung der Schloßzunge im Schloßgehäuse gegen Abgleiten vom Halteteil gesichert sind. Da das Halteteil ein Bestandteil des vom Schloßgehäuse im wesentlichen verkleideten Schloßrahmens ist, benötigt es beträchtlichen Platz, weil es außerhalb des eigentlichen Schloßgehäuses vorgesehen sein muß. Ferner weist das Schloßgehäuse eine aus relativ vielen Einzelteilen bestehende Mechanik auf, mit deren Hilfe ein Gurtband-Endstück formschlüssig arretiert auf dem Halteteil gesichert ist. Diese Mechanik verursacht wegen ihrer Einzelteile entsprechend hohe Fertigungskosten, und es besteht die Gefahr, daß wegen Verschleißes dieser Teile die Funktionssicherheit, insbesondere die Entriegelung der Gurtband-Endstücke im Notfall, gefährdet ist. Auch ist das Zusammenstecken des Gurtschlosses noch verbesserungsbedürftig, da wenigstens eines der aufgesteckten Endstücke beim Einführen der Schloßzunge noch besonders festgehalten werden muß, was zu einer umständlichen Handhabung des Gurtschlosses führt. Schließlich kann die Schloßzunge auch dann verrastet werden, wenn nicht sämtliche Gurtband-Endstücke auf dem erwähnten Halteteil aufgesteckt sind, wobei auch der Verrastungsvorgang der Schloßzunge ggf. zusätzliche Handgriffe erfordert und somit auch hierdurch die Schloßbedienung erschwert ist.A known buckle of this type enables the webbing end pieces to be plugged onto a common holding part, these end pieces being secured against sliding off the holding part after the lock tongue has been locked in the lock housing. Since the holding part is part of the lock frame which is essentially clad by the lock housing, it requires considerable space because it must be provided outside the actual lock housing. Furthermore, the lock housing has a mechanism consisting of a relatively large number of individual parts, with the aid of which a strap end piece is secured in a form-locking manner on the holding part. This mechanism causes correspondingly high manufacturing costs because of its individual parts, and there is a risk that the functional safety, in particular the unlocking of the belt end pieces in an emergency, is endangered due to wear of these parts. The plugging together of the belt buckle is still in need of improvement, since at least one of the plugged-on end pieces has to be particularly firmly held when the lock tongue is inserted, which leads to cumbersome handling of the belt buckle. Finally, the lock tongue can be locked even if not all of the webbing end pieces are attached to the holding part mentioned, the locking process of the lock tongue also possibly requiring additional manipulations and thus also making the lock operation difficult.

Die Aufgabe der Erfindung besteht in der Schaffung eines Gurtschlosses der einleitend angeführten Art, das in seinem Aufbau weiter vereinfacht, kompakter gestaltet und in seiner Bedienung erleichtert und sicherer gemacht ist sowie hinsichtlich der Verrastung der Schloßzunge verbessert ist.The object of the invention is to provide a belt buckle of the type mentioned in the introduction, which is further simplified in its construction, is more compact in design, is easier to operate and made safer, and is improved with regard to the latching of the buckle tongue.

Die Lösung dieser Aufgabe geht von dem angegebenen Gurtschloß aus und kennzeichnet sich dadurch, daß die Gurtband-Endstücke bei einer durch Formschluß festgelegten Anlage aneinander mit ihren Aufsteckschlitzen fluchten, daß die Schloßzunge von einer Seite her durch die Schlitze steckbar ist und daß der auf der anderen Seite aus den Aufsteckschlitzen herausragende Abschnitt der Zunge in dem Gehäuse verriegelbar ist, nachdem wenigstens ein an dem dem Gehäuse benachbarten Gurtband-Endstück vorgesehenes Steuerorgan durch Verstellung eines federbelasteten Riegels dessen Sperrstellung aufgehoben hat.The solution to this problem is based on the specified buckle and is characterized in that the belt end pieces are aligned with one another with their attachment slots in a system defined by positive locking, that the buckle tongue can be inserted from one side through the slots and that on the other Side protruding from the plug-in slots of the tongue in the housing can be locked after at least one control member provided on the belt end piece adjacent to the housing has released its locked position by adjusting a spring-loaded latch.

Ein derartiges Gurtschloß ist in seinem Aufbau weiter vereinfacht und kompakter ausgestaltet, da ein entsprechend groß bemessenes gemeinsames Halteteil für die Gurtband-Endstücke am Schloßgehäuse entfällt. Stattdessen sitzen die Endstücke auf einem relativ kurzen Abschnitt der Schloßzunge. Die Bedienung, insbesondere das Zusammenstecken des Schlosses, ist insofern vereinfacht, als daß die Gurtband-Endstücke zunächst miteinander gekuppelt und so auf die Schloßzunge aufgesteckt werden, die dann mit dem übrigen Schloß verrastet und verriegelt wird, was insgesamt leicht und schnell durchgeführt werden kann, wobei die miteinander verbunden Endstücke und die Schloßzunge beim Verrastungsvorgang auf einfache Weise mit der Hand zusammengehalten und geführt werden können. Die Verrastung der Schloßzunge im übrigen Schloß ist insofern sicherer gestaltet, als daß die Zunge nicht ohne weiteres oder leichtfertig in ihre Rastlage gebracht werden kann, sondern dies ist erst nach Freigabe der Rastposition durch einen Riegel möglich. Dieser wird jedoch erst dann betätigt, wenn beide Gurtband-Endstücke in richtiger Lage auf der Zunge sitzen, da eines der Endstücke das den Riegel verstellende Steuerorgan aufweist. Weitere vorteilhafte Merkmale der Erfindung ergeben sich aus der vorzugsweisen Ausgestaltung gemäß den Unteransprüchen.The structure of such a buckle is further simplified and more compact, since there is no need for a correspondingly large common holding part for the strap end pieces on the buckle housing. Instead, the end pieces sit on a relatively short section of the lock tongue. The operation, in particular the plugging together of the lock, is simplified in that the strap end pieces are first coupled together and thus plugged onto the lock tongue, which is then locked and locked with the rest of the lock, which can be carried out easily and quickly overall. wherein the interconnected end pieces and the lock tongue can be easily held and guided by hand during the latching process. The locking of the lock tongue in the rest of the lock is designed to be safer in that the tongue cannot be easily or lightly brought into its locked position, but this is only possible after the locking position has been released by a bolt. However, this is only activated when both webbing end pieces are seated in the correct position on the tongue, since one of the end pieces has the control element adjusting the bolt. Further advantageous features of the invention result from the preferred embodiment according to the subclaims.

Die Erfindung ist nachstehend anhand eines in den anliegenden Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. Die Zeichnungen zeigen in schematischer Darstellung :

The invention is explained below with reference to an embodiment shown in the accompanying drawings. The drawings show in a schematic representation:
  • FIG. 1 shows a top view of the embodiment shown essentially exploded,
  • FIG. 2 shows a top view of the assembled embodiment with the lock housing missing,

Gemäß Figur 1 besteht das dargestellte Gurtschloß aus dem Schloßgehäuse 1, das in seinem Innern den üblichen Sperrund Auslösemechanismus enthält, der weiter unten näher erläutert ist, aus der Schloßzunge 2 sowie mindestens aus den beiden Endstücken 3 und 4 zur Befestigung an den Enden 5 von nicht weiter dargestellten Schultergurten. Die vorzugsweise vollständig aus Kunststoff bestehenden Endstücke 3 und 4 weisen außer den üblichen Bereichen zur Befestigung der Schuftergurte zwei den Gurtschloßteilen 1 und 2 zugekehrten Arme 6 bzw. 7 auf, wobei jeder Arm einen Schlitz 8 bzw. 9 aufweist. Diese Schlitze fluchten miteinander, wenn die Arme 6, 7 in ihrer vorbestimmten Betriebslage gegeneinander zur Anlage gebracht sind, wie es aus den Figuren 1 und 2 hervorgeht. Durch diese Schlitze wird die Schloßzunge 2 hindurchgesteckt, wobei dann die beiden Arme 6, 7 auf dem Abschnitt 2a der Zunge 2 zu liegen kommen. Der Abschnitt 2b der Zunge 2 erstreckt sich in üblicher Weise in das Schloßgehäuse 1 und rastet in dieses ein. Hierzu zeigt Figur 2, wie die Arme 6 und 7 auf dem Abschnitt 2a sitzen, wobei der Abschnitt 2b der Zunge 2 auf der anderen Seite der Schlitze herausragt, so daß dieser Abschnitt in das Schloßgehäuse 1 eingesteckt werden kann. Außer dem Abschnitt 2a ist die Schloßzunge 2 in ihrem übrigen Aufbau bekannt, so daß sie nicht weiter erläutert zu werden braucht.According to Figure 1, the belt buckle shown consists of the lock housing 1, which contains the usual locking and release mechanism inside, which is explained in more detail below, from the lock tongue 2 and at least from the two end pieces 3 and 4 for attachment to the ends 5 of not further illustrated Shoulder straps. The end pieces 3 and 4, which are preferably made entirely of plastic, have two arms 6 and 7 facing the buckle parts 1 and 2 in addition to the usual areas for fastening the sling belts, each arm having a slot 8 and 9, respectively. These slots are aligned with one another when the arms 6, 7 are brought into abutment against one another in their predetermined operating position, as can be seen from FIGS. 1 and 2. The lock tongue 2 is inserted through these slots, the two arms 6, 7 then coming to rest on the section 2a of the tongue 2. The section 2b of the tongue 2 extends in the usual way into the lock housing 1 and engages in it. 2 shows how the arms 6 and 7 sit on the section 2a, the section 2b of the tongue 2 protruding on the other side of the slots, so that this section can be inserted into the lock housing 1. In addition to section 2a, the lock tongue 2 is known in its remaining structure, so that it need not be explained further.

Der Abschnitt 2a der Schloßzunge 2 ist gemäß Figur 1 in Aufsteckrichtung der Zunge verjüngt ausgebildet, und dies ist ebenfalls entsprechend bei den Aufsteckschlitzen 8 und 9 der Arme 6 bzw. 7 der Fall. Hierdurch wird vermieden, daß die Schloßzunge 2 in dem Schloßgehäuse 1 bei nur einem aufgesteckten Endstück oder bei falsch aufgestecktem Endstück verrastet werden kann. Sollte der Fall eintreten, daß das Endstück 4 allein auf den Abschnitt 2a aufgesteckt wird, so kann letztlich eine Verriegelung der Schloßzunge 2 nicht erfolgen, da aufgrund des Spieles zwischen dem Abschnitt 2a und dem Aufsteckschlitz 9 des Armes 7 dieser Arm immerhin noch soweit zurückgeschoben wird, daß die an ihm gehäuseseitig vorgesehenen Steuerorgane 10 noch nicht voll wirksam werden können, so daß eine Verrastung des Zungenabschnittes 2b nicht erfogen kann.The section 2a of the lock tongue 2 is tapered according to FIG. 1 in the plug-on direction of the tongue, and this is likewise the case with the plug-in slots 8 and 9 of the arms 6 and 7, respectively. This avoids that the lock tongue 2 can be locked in the lock housing 1 with only one end piece plugged in or with the end piece fitted incorrectly. Should the case occur that the end piece 4 is only plugged onto the section 2a, then ultimately the lock tongue 2 cannot be locked, since due to the play between the section 2a and the insertion slot 9 of the arm 7 this arm is still pushed back as far that the control elements 10 provided on the housing side thereof cannot yet become fully effective, so that a latching of the tongue section 2b cannot be achieved.

Wie deutlicher aus den Figuren 3 und 4 zu ersehen ist, ist der Arm 6 des einen Gurtband-Endstückes 3 mit einem Steg 11 versehen, der sich vom Arm 6 seitwärts und gemäß den Figuren 1 und 2 über den Arm 7 des anderen Endstüpkes 4 erstreckt. Dieser Steg 11 ist mit einem Vorsprung 12 versehen, der in eine entsprechende Vertiefung 13 des Armes 7 des anderen Endstückes 4 formschlüssig eingreift. Der Steg 11 und der an ihm vorgesehene Vorsprung 12 sowie die Vertiefung 13 erstrecken sich - in Steckrichtung der Schloßzunge 2 gesehen - quer zu der Zunge und weisen zu ihr einen Abstand auf.As can be seen more clearly from FIGS. 3 and 4, the arm 6 of the one webbing end piece 3 is provided with a web 11 which extends sideways from the arm 6 and according to FIGS. 1 and 2 over the arm 7 of the other end piece 4 . This web 11 is provided with a projection 12 which positively engages in a corresponding recess 13 in the arm 7 of the other end piece 4. The web 11 and the projection 12 provided on it and the recess 13 extend — seen in the insertion direction of the lock tongue 2 — transversely to the tongue and are at a distance from it.

Bevor die Endstücke 3 und 4 auf den Abschnitt 2a der Schoßzunge 2 aufgesteckt werden, werden zunächst die Arme 6 und 7 gegeneinander so zur Anlage gebracht, daß der Vorsprung 12 in die Vertiefung 13 eingreift, wodurch die Aufsteckschlitze 8 und 9 zueinander in Fluchtlage gebracht sind. Die so miteinander gekuppelten Endstücke 3 und 4 können nun leicht gemeinsam auf den Abschnitt 2a der Schloßzunge 2 aufgesteckt werden. Der aufgesteckte Zustand ist in Figur 2 dargestellt.Before the end pieces 3 and 4 are attached to the section 2a of the lap tongue 2, the arms 6 and 7 are first brought into abutment against one another in such a way that the projection 12 engages in the recess 13, as a result of which the plug-in slots 8 and 9 are brought into alignment with one another . The end pieces 3 and 4 which are coupled to one another in this way can now easily be pushed together onto the section 2a of the lock tongue 2. The attached state is shown in Figure 2.

Obwohl es sich als vorteilhaft erwiesen hat, daß der Vorsprung 12 und die Vertiefung 13 in Form einer Nut-Feder-Ausbildung gestaltet sind, können jedoch auch andere Formschlußausbildungen angewendet werden, z. B. ein Zapfen, der in eine entsprechende Ausnehmung eingreift. Ferner ist es auch möglich, daß das vorspringende Formschlußmittel am Arm 7 und das aufnehmende Formschlußmittel am Arm 6 vorgesehen ist.Although it has proven to be advantageous that the projection 12 and the recess 13 are designed in the form of a tongue and groove design, other form-fitting designs can also be used, e.g. B. a pin which engages in a corresponding recess. Furthermore, it is also possible that the projecting positive locking means is provided on the arm 7 and the receiving positive locking means is provided on the arm 6.

Wie bereits erwähnt, weist der Arm 7 des Gurtband-Endstückes 4 zwei vorspringende Steuerorgane 10 auf. Diese Steuerorgane kommen beim Einschieben der Schloßzunge 2 in das Schloßgehäuse 1 gegen die beiden Schenkel 14a eines vorzugsweise aus Kunststoff bestehenden, U-förmigen Riegels 14 zur Anlage und drücken den Riegel zurück, wie es aus den Figuren 5 und 6 zu ersehen ist. Im Stegbereich 14b weist der Riegel 14 vorzugsweise zwei Sperransätze 15 auf, die sich in Richtung zum Einsteckschlitz des Schloßgehäuses 1 erstrecken, und zwar in Sperrlage des Riegels 14 soweit, daß sie den Eingang zur Rastlage der Schloßzunge 2 sperren, wie es am besten aus Figur 6 zu erkennen ist. Dies hat zur Folge, daß der Raststeg 2c der Schloßzunge 2 nicht in seine Rastlage gelangen kann, welche durch den üblichen metallischen Rahmen 16 und dessen Rastnocken 16a definiert ist. Wird nun die Schloßzunge zusammen mit den Armen 6 und 7 weiter in das Schloßgehäuse 1 hineingedrückt, so wird der Riegel 14 mittels der Steuerorgane 10 in seine Freigabelage gemäß Figur 7 geschoben. Bei dieser Bewegung wird auch gleichzeitig ein winkelförmiger, am Rahmen 16 schwenkbar gelagerter Niederhalter 17 entgegen der Kraft einer nicht dargestellten Feder zurückgeschwenkt, so daß der Steg 2c der Schloßzunge 2 nunmehr in seine Rastlage gelangen kann. In dieser Lage ist der Niederhalter 17 durch die erwähnte Feder zurückgeschwenkt und bewirkt eine Verriegelung der Schloßzunge 2 in dem Schloßgehäuse 1.As already mentioned, the arm 7 of the belt end piece 4 has two projecting control members 10. When the lock tongue 2 is inserted into the lock housing 1, these control elements come to rest against the two legs 14a of a U-shaped bolt 14, which is preferably made of plastic, and press the bolt back, as can be seen from FIGS. 5 and 6. In the web area 14b, the bolt 14 preferably has two locking lugs 15, which extend in the direction of the insertion slot of the lock housing 1, in the locked position of the bolt 14 to such an extent that they block the entrance to the locking position of the lock tongue 2, as best shown in FIG 6 can be seen. This has the consequence that the latching web 2c of the lock tongue 2 cannot get into its latched position, which is defined by the usual metallic frame 16 and its latching cams 16a. If the lock tongue together with the arms 6 and 7 is now pressed further into the lock housing 1, the bolt 14 is pushed into its release position according to FIG. 7 by means of the control elements 10. During this movement, at the same time an angular hold-down device 17 which is pivotably mounted on the frame 16 is pivoted back against the force of a spring, not shown, so that the web 2c of the lock tongue 2 can now reach its latched position. In this position, the hold-down device 17 is pivoted back by the spring mentioned and causes the lock tongue 2 to lock in the lock housing 1.

Zur Entriegelung der Schloßzunge 2 und damit auch der Gurtband-Endstücke 3 und 4 wird folgendermaßen vorgegangen. In üblicher Weise wird eine Taste 18 durch Fingerdruck niedergedrückt, wodurch der winkelförmige Niederhalter 17 gegen die Kraft einer nicht dargestellten Feder wieder zurückgeschwenkt wird, so daß der Steg 2c der Schloßzunge 2 freigegeben wird und dieser ausgestoßen werden kann. Hierzu ist vorzugsweise eine integrierte, aus dem Material des Schloßgehäuses 1 bestehende, zungenartige Hilfsfeder 19 vorgesehen, die eine entsprechende Ausnehmung 20 im Rahmen 16 durchgreift und am Steg 2c der Zunge 2 anliegt. Diese Hilfsfeder bewirkt, ein sicheres Ausstoßen der Schloßzunge aus ihrer Rastlage, wobei der wieder nach vorn schwenkende Niederhalter 17 die Schloßzunge schließlich aus dem Gehäuse 1 ausstößt. Dabei wird gleichzeitig auch der Riegel 14 mittels einer Feder 21 in seine aus den Figuren 1 und 6 entnehmbare Sperrlage zurückgeschoben.The procedure for unlocking the lock tongue 2 and thus also the belt end pieces 3 and 4 is as follows. In a conventional manner, a button 18 is depressed by finger pressure, whereby the angular hold-down device 17 is pivoted back against the force of a spring, not shown, so that the web 2c of the lock tongue 2 is released and can be ejected. For this purpose, an integrated, tongue-like auxiliary spring 19, preferably made of the material of the lock housing 1, is provided, which extends through a corresponding recess 20 in the frame 16 and bears against the web 2c of the tongue 2. This auxiliary spring causes the lock tongue to be reliably ejected from its latched position, the hold-down device 17, which again swivels forward, finally ejects the lock tongue from the housing 1. At the same time, the bolt 14 is also pushed back into its blocking position which can be seen in FIGS. 1 and 6 by means of a spring 21.

Beim vorstehend beschriebenen Ausführungsbeispiel sind zwei Gurtband-Endstücke 3 und 4 verwendet, die an den Enden von Schultergurten befestigt werden. In Weiterbildung kann auch so vorgegangen werden, daß ein Schrittgurt mit einem Endstück versehen wird, das ebenfalls einen Arm aufweist, der dann zusammen mit den Armen 6 und 7 der Endstücke 3 und 4 auf den entsprechend längeren Abschnitt 2a der Schloßzunge 2 geschoben wird. Auch ein solches Gurtschloß ist kompakt und leicht in seinem Aufbau, leicht zu bedienen und ebenfalls funktionssicher. Der übrige Aufbau des Gurtschlosses ist in diesem Fall wie vorstehend beschrieben, wobei noch zu erwähnen ist, daß die Enden des Beckengurtes in üblicher Weise an der Schloßzunge und am Schloßgehäuse befestigt werden.In the embodiment described above For example, two webbing end pieces 3 and 4 are used, which are attached to the ends of shoulder straps. In a further development it can also be done that a crotch strap is provided with an end piece which also has an arm which is then pushed together with the arms 6 and 7 of the end pieces 3 and 4 onto the correspondingly longer section 2a of the lock tongue 2. Such a buckle is also compact and light in structure, easy to use and also functionally reliable. The rest of the structure of the buckle in this case is as described above, and it should also be mentioned that the ends of the lap belt are fastened to the buckle tongue and the buckle housing in the usual way.
