Abstract

The buckle comprises a locking mechanism and at least one ejectable seat-belt end piece (2) which can be inserted into the latter and has a buckle latch (4) lockable by means of the mechanism. The mechanism consists of a U-shaped metal frame (7), of a locking element (8) mounted in the lateral cut-outs of the latter and intended for locking the buckle latch, an ejector (9) for the buckle latch (4), a locking- element support (10), and of a release button (11). In order to further simplify the buckle and to be able to manufacture it more cheaply, the locking element (8) is designed as a component in the form of a small plate and the lateral cut-outs (18) in the metal frame (7) for mounting the locking element (8) consist of elongate holes in the frame which extend parallel to the direction of motion of the buckle latch (4) and are dimensioned such that the pins (19) of the locking element (8) can be moved in the direction of motion of the buckle latch but are guided essentially without play perpendicularly thereto. The web part (22) of the U-shaped metal frame (7) has a stop (24) for fixing the locking position of the locking element (8) and the locking-element support (10) is arranged behind the locking element, above the ejector (9), and can be moved at least essentially parallel to the direction of motion of the ejector. <IMAGE>

Description

Die Erfindung geht aus von einem Gurtschloß für Grutband­rückhaltesysteme, umfassend einen Schließmechanismus und wenigstens ein in diesen einsteckbares, infolge Tasten­druck auswerfbares Gurtband-Endstück, wobei das Endstück eine mit dem Mechanismus mit Hilfe eines endstückseitigen Steuerorgans verriegelbare Zunge aufweist und wobei der Mechanismus aus einem U-förmigen Metallrahmen mit einem mittels Zapfen in dessen seitlichen Ausnehmungen gelagerten Sperrglied für die Verriegelung der Zunge des Endstückes, einem federbelasteten, die Zunge betätigenden Auswerfer, einer federbelasteten Sperrgliedstütze zur Sicherung we­nigstens der Raststellung des Sperrgliedes und aus einer federbelasteten Auslösetaste besteht.The invention is based on a belt buckle for conveyor belt restraint systems, comprising a locking mechanism and at least one belt strap end piece which can be inserted into it and can be ejected as a result of a push of a button, the end piece having a tongue which can be locked with the mechanism with the aid of a control member on the end piece, and the mechanism consisting of a U- Shaped metal frame with a locking member mounted in the lateral recesses for locking the tongue of the end piece, a spring-loaded, tongue-actuating ejector, a spring-loaded locking member support for securing at least the latching position of the locking member and a spring-loaded release button.

In der EP-OS 0 252 403 ist ein Gurtschloß der vorgenannten Art beschrieben. Bei diesem Schloß ist das Sperrglied re­lativ kompliziert aufgebaut und weist eine beträchtliche Masse auf, so daß das Sperrglied zeitaufwendig und mit hohen Kosten gefertigt werden muß und ferner bei seiner Betätigung relativ hohe Reibungskräfte überwunden werden müssen. Das Sperrglied ist ein relativ großes Bauteil und besitzt eine schräg nach unten abgebogene Rastnase zur Verriegelung mit dem Zungenteil des Gurtband-Endstückes, die genau gebogen werden muß, um die Funktion des Gurt­schlosses unter allen Umständen sicherzustellen. Außer­dem ist die Masse dieses Sperrgliedes relativ hoch, so daß in Verbindung mit den beträchtlichen Reibwiderständen bei der Schloßbedienung erhebliche Betätigungskräfte auf­gebracht werden müssen.A belt buckle of the aforementioned type is described in EP-OS 0 252 403. In this lock, the locking member is relatively complicated and has a considerable Mass on, so that the locking member must be manufactured time-consuming and at high cost and also relatively high friction forces must be overcome when it is actuated. The locking member is a relatively large component and has an obliquely bent down latch for locking with the tongue part of the webbing end piece, which must be bent precisely to ensure the function of the buckle under all circumstances. In addition, the mass of this locking member is relatively high, so that considerable operating forces must be applied in connection with the considerable frictional resistances when operating the lock.

In der EP-OS 0 083 752 ist ein vergleichbares Gurtschloß offenbart. Auch bei dem Sperrglied dieses Schlosses sind die vortehend aufgeführten Nachteile vorhanden, wobei das Sperrglied noch komplizierter aufgebaut ist.A comparable belt buckle is disclosed in EP-OS 0 083 752. The above-mentioned disadvantages are also present in the locking member of this lock, the locking member being even more complicated.

Die Aufgabe der Erfindung besteht in der Verbesserung eines Gurtschlosses der einleitend angeführten Art dahingehend, daß das Sperrglied, seine Lagerung und seine Betätigung weiter vereinfacht sind, um das Gurtschloß kostengünstiger und einfacher herstellen sowie leichter bedienen zu können.The object of the invention is to improve a buckle of the type mentioned above in that the locking member, its storage and its actuation are further simplified in order to manufacture the buckle more cost-effectively and easily, and to operate it more easily.

Die Lösung dieser Aufgabe geht von dem einleitend ange­führten Gurtschloß aus und kennzeichnet weiter dadurch, daß das Sperrglied ein zumindest im wesentlichen ebenes plättchenförmiges Bauteil ist, das die seitlichen Aus­nehmungen in dem Metallrahmen für die Halterung und Führung der Zapfen des Sperrgliedes aus Langlöchern bestehen, die sich parallel zur Bewegungsrichtung der Zunge im Rahmen erstrecken und derart bemessen sind, daß die Zapfen in Bewegungsrichtung der Zunge beweglich, jedoch senkrecht dazu und wenigstens in Verriegelungsposition des Sperr­gliedes im wesentlichen spielfrei geführt sind, daß der Stegteil des U-förmigen Metallrahmens einen Anschlag zur Fixierung der Raststellung des Sperrgliedes aufweist, daß der vordere Oberbereich des Sperrgliedes einen Anschlag zwecks Sperrgliedentriegelung durch die Auslösetaste bildet und daß die Sperrgliedstütze hinter dem Sperrglied oberhalb des Auswerfers angeordnet und zumindest im we­sentlichen parallel zur Bewegungsrichtung des Auswerfers beweglich ist.The solution to this problem is based on the above-mentioned belt buckle and further characterized in that the locking member is an at least substantially flat plate-shaped component that the lateral recesses in the metal frame for holding and guiding the pin of the locking member consist of elongated holes that are extend parallel to the direction of movement of the tongue in the frame and are dimensioned such that the pin in Movement direction of the tongue movable, but perpendicular to it and at least in the locking position of the locking member are guided essentially free of play, that the web part of the U-shaped metal frame has a stop for fixing the locking position of the locking member, that the front upper region of the locking member has a stop for unlocking the locking member by Trigger button forms and that the locking member support is arranged behind the locking member above the ejector and is movable at least substantially parallel to the direction of movement of the ejector.

Durch diese Lösung ist das Sperrglied in seiner Form weiter vereinfacht. Es ist durch einen einzigen Stanz­vorgang herstellbar und benötigt keinerlei Biegearbeits­gänge zur weiteren Formgebung. Seine dadurch bedingte kleinere Baugröße führt zu einer kleineren Masse mit dem Vorteil, daß dieses aus Metall bestehende Glied nun weniger Betätigungskräfte erfordert. Letzteres auch deshalb, weil es bei seiner Schließ- und Öffnungsbetätigung kleineren Reibungskräften ausgesetzt ist, zumal es erfindungsgemäß im Prinzip mit relativ großem Spiel in den Langlöchern gelagert ist. Jedoch wird in jedem Falle eine sichere Raststellung des Sperrgliedes erreicht, weil es einer­seits in Querrichtung zur Längserstreckung der seitlichen Langlöcher, zumindest in Rastposition, nicht beweglich ist und sich andererseits unten am Metallrahmen des Gurt­schlosses abstützt. Die rückwärtige, entsprechend gut abgefederte Sperrgliedstütze drückt auf die Rückseite des Sperrgliedes, um ein Herausfallen dieses Gliedes aus seiner Raststellung zu vermeiden. Zum Öffnen des Gurt­schlosses wird das Sperrglied oben durch die Auslösetaste direkt zurückgedrückt, so daß sich das Sperrglied in den beiden Langlöchern zurückbewegt und dabei in eine Schräg­lage kommt, derart, daß es sich aus der Zunge des Gurt­band-Endstückes zurückzieht, so daß dieses entriegelt ist.This solution further simplifies the shape of the locking member. It can be produced by a single punching process and does not require any bending operations for further shaping. Its resulting smaller size leads to a smaller mass with the advantage that this link made of metal now requires less actuation forces. The latter also because it is exposed to smaller frictional forces when it is closed and opened, especially since, according to the invention, it is in principle stored in the elongated holes with a relatively large amount of play. However, a secure locking position of the locking member is achieved in any case, because on the one hand it is not movable in the transverse direction to the longitudinal extension of the lateral elongated holes, at least in the locking position, and on the other hand it is supported at the bottom on the metal frame of the buckle. The rear, correspondingly well sprung locking member support presses on the back of the locking member in order to prevent this link from falling out of its locked position. To open the belt buckle, the locking element is opened by pressing the release button directly pushed back, so that the locking member moves back in the two elongated holes and thereby comes to an inclined position, such that it retracts from the tongue of the belt end piece, so that it is unlocked.

Die Nichtverriegelungsstellung des im wesentlichen recht­eckig ausgebildeten Sperrgliedes ist durch eine nach hinten geneigte Schräglage desselben gesichert, die einerseits durch eine hintere erhöhte Anlage des geneigten Sperr­gliedes an der Sperrgliedstütze und andererseits durch eine vordere untere Anlage des Sperrgliedes an einem Ge­häuseteil des Schlosses in Verbindung mit der oberen An­lage der Sperrgliedzapfen an den Langlöchern gesichert ist.The non-locking position of the substantially rectangular locking member is secured by a backward inclined inclined position thereof, which is achieved on the one hand by a rear raised contact of the inclined locking member on the locking member support and on the other hand by a lower front contact of the locking member on a housing part of the lock in connection with the upper one System of the pawl pin is secured to the elongated holes.

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

  • Figuren 1 bis 3 jeweils Mittellängsschnitte durch das Ausführungsbeispiel, und zwar beim Ein­führen von Gurtband-Endstücken, nach Verriegelung der Endstücke und beim Ent­riegeln der Endstücke, wobei letztere schon ausgeworfen sind,
  • Figur 4 einen vereinfachten Teilschnitt nach der Linie IV-IV in Figur 2,
  • Figur 5 eine Aufsicht auf ein Einzelteil des Ausführungsbeispieles.
The invention is explained below with reference to an embodiment shown in the accompanying drawings. Show it:
  • FIGS. 1 to 3 each show longitudinal longitudinal sections through the exemplary embodiment, namely when inserting webbing end pieces, after locking the end pieces and when unlocking the end pieces, the latter already being ejected,
  • FIG. 4 shows a simplified partial section along the line IV-IV in FIG. 2,
  • Figure 5 is a plan view of an individual part of the embodiment.

Nach den Figuren 1 bis 3 besteht das Gurtschloß haupt­sächlich aus einem Schloßgehäuse 1 mit einem darin be­ findlichen Schließmechanismus und aus zwei Gurtband-­Endstücken 2 und 3. Von dem einen Endstück 2 ist nur die Zunge 4, die mit ihrem Verriegelungsloch 5 mit dem Mecha­nismus verriegelt wird, zu sehen, während das andere End­stück 3 ein Steuerorgan 6 aufweist, das ebenfalls mit dem Mechanismus in Eingriff gelangt. Es kann auch ein einziges Gurtband-Endstück verwendet werden, das dann auch das Steuerorgan 6 aufweist. Auch ist es möglich, mehr als zwei Endstücke zu verwenden.According to Figures 1 to 3, the belt buckle consists mainly of a lock housing 1 with a be in it sensitive locking mechanism and two webbing end pieces 2 and 3. Of the one end piece 2, only the tongue 4, which is locked with its locking hole 5 with the mechanism, can be seen, while the other end piece 3 has a control element 6, which also with the mechanism engages. A single strap end piece can also be used, which then also has the control element 6. It is also possible to use more than two end pieces.

Der erwähnte Mechanismus umfaßt einen U-förmigen Metall­rahmen 7, ein daran gelagertes Sperrglied 8 für die Ver­riegelung der Zunge 4, einen druckfederbelasteten, üb­lichen Auswerfer 9 für die entriegelte Zunge, eine Sperr­gliedstütze 10, die rückwärtig an dem Sperrglied 8 an­greift, und eine druckfederbelastete Auslösetaste 11, die oben am Sperrglied angreift und vorzugsweise parallel zur Bewegungsrichtung der Zunge 4 bewegbar ist. Für die Teile 9, 10 und 11 wird vorzugsweise eine wendelförmige Druckfeder 12, 13 und 14 verwendet. Der Stegteil des Metallrahmens 7 besitzt einen hinteren Fortsatz 15 mit einem Loch 16, voran in bekannter Weise ein (nicht ge­zeigtes) Gurtband befestigt wird.The mechanism mentioned comprises a U-shaped metal frame 7, a locking member 8 mounted thereon for locking the tongue 4, a compression spring-loaded, common ejector 9 for the unlocked tongue, a locking member support 10 which acts on the rear of the locking member 8, and a compression spring-loaded release button 11, which engages the locking member at the top and is preferably movable parallel to the direction of movement of the tongue 4. A helical compression spring 12, 13 and 14 is preferably used for parts 9, 10 and 11. The web part of the metal frame 7 has a rear extension 15 with a hole 16, before a webbing (not shown) is attached in a known manner.

Die beiden sich gegenüberliegenden Schenkel 17 des U-­förmigen Metallrahmens 7 (Figur 4) weisen je ein recht­eckiges Langloch 18 zur Halterung und Führung des Sperr­gliedes 8 auf, die derart angeordnet sind, daß sich die beiden Langlöcher parallel zur Bewegungsrichtung der Zunge 4 in dem Mechanismus erstrecken und je in einem solchen Bereich der Schenkel 17 vorgesehen sind, der etwa über dem Verriegelungsloch 5 der Zunge 4 liegt, wenn diese in dem Mechanismus eingerastet ist.The two opposite legs 17 of the U-shaped metal frame 7 (Figure 4) each have a rectangular slot 18 for holding and guiding the locking member 8, which are arranged such that the two slots parallel to the direction of movement of the tongue 4 in the mechanism extend and are each provided in such an area of the leg 17, which is approximately above the Locking hole 5 of the tongue 4 is when it is snapped into the mechanism.

Das plättchenförmige und im wesentlichen rechteckig aus­gebildete Sperrglied 8 (Figur 4) weist an seinen kurzen Seiten je einen Zapfen 19 auf, wobei die Zapfen in den Langlöchern 18 gehaltert und geführt sind, wie aus den Figuren 1 bis 3 zu erkennen ist. Das Sperrglied hat weiter eine untere mittige Sperrnase 20, die in das Verriegelungs­loch 5 der Zunge 4 eingreift, und einen oberen Anschlag 21, der zur Entriegelung des Mechanismus durch die Aus­lösetaste 11 dient. Das Sperrglied 8 ist vorzugsweise eben ausgebildet, kann aber auch leicht gekrümmt sein, bei­spielsweise in seinem Oberbereich,und besteht z.B. aus Metall.The plate-shaped and essentially rectangular blocking member 8 (FIG. 4) has a pin 19 on each of its short sides, the pins being held and guided in the elongated holes 18, as can be seen from FIGS. 1 to 3. The locking member further has a lower central locking lug 20 which engages in the locking hole 5 of the tongue 4, and an upper stop 21 which serves to unlock the mechanism by the release button 11. The locking member 8 is preferably flat, but can also be slightly curved, for example in its upper region, and consists e.g. made of metal.

Die Breite der Zapfen 19 entspricht im wesentlichen der Höhe der Langlöcher 18, so daß das Sperrglied 8, wenn es vertikal steht, wie die Figuren 2 und 4 zeigen,sich nicht in vertikaler Richtung bewegen kann, insoweit also fixiert ist. In Längsrichtung der Langlöcher dagegen können sich die Zapfen bewegen, und zwar aufgrund der um ein Vielfaches größeren Länge der Langlöcher in bezug auf die Dicke der Zapfen, so daß das Sperrglied gemäß den Figuren 1 und 3 eine Schräglage, die die Ausraststellung des Sperrgliedes ist, einnehmen kann.The width of the pin 19 corresponds essentially to the height of the elongated holes 18, so that the locking member 8, when it is vertical, as shown in FIGS. 2 and 4, cannot move in the vertical direction, that is, it is fixed in this respect. In contrast, the pins can move in the longitudinal direction of the elongated holes, because of the many times longer length of the elongated holes with respect to the thickness of the pins, so that the locking member according to FIGS. 1 and 3 is in an inclined position, which is the disengaged position of the locking member. can take.

Der Metallrahmen 7 besitzt in seinem die beiden Schenkel 17 verbindenden Stegteil 22 eine übliche, längliche Führungs­ausnehmung 23 zur Aufnahme und axialen Führung des Aus­werfers 9 bekannten Aufbaues, der in Verbindung mit der Druckfeder 12 die Zunge 4 des Endstückes 2 bei entriegel­tem Sperrglied 8 auswirft. Auf dem Auswerfer 9 stützt sich auch das Sperrglied 8 ab, wenn letzteres entriegelt ist (Figuren 1 und 3). Das vordere Ende der als Stanzloch gebildeten Ausnehmung 23 dient gleichzeitig auch als Anschlag 24 für die Sperrnase 20 des Sperrgliedes, wenn letzteres eingerastet ist (Figur 2), so daß auch dadurch die Raststellung des Sperrgliedes gesichert ist.The metal frame 7 has in its web part 22 connecting the two legs 17 a conventional, elongated guide recess 23 for receiving and axially guiding the ejector 9 of known construction, which in conjunction with the compression spring 12 ejects the tongue 4 of the end piece 2 when the locking member 8 is unlocked. The ejector 9 is supported also the locking member 8 from when the latter is unlocked (Figures 1 and 3). The front end of the recess 23 formed as a punched hole also serves as a stop 24 for the locking lug 20 of the locking member when the latter is engaged (FIG. 2), so that the locking position of the locking member is thereby also secured.

Oberhalb des Auswerfers 9 und hinter dem Sperrglied 8 ist die Sperrgliedstütze 10 angeordnet, und zwar zumindest im wesentlichen parallel zur Bewegungsrichtung des Aus­werfers axialbeweglich, so daß sich die Stütze 10 beim Verriegeln der Zunge 4 vorbewegt aufgrund der Druckfeder 13 und beim Drücken der Auslösetaste 11 gemäß dem Pfeil 25 zurückbewegt. Wie die Figuren 1 und 3 zeigen, greift die Stütze 10 rückwärtig etwa mittig an dem Sperrglied 8 an und bewirkt so ein Einrastmoment an dem Sperrglied, da dieses im Bereich seiner Sperrnase und während seiner Entriegelungszeit an einem Ergänzungsteil 1a des Gehäuses 1 zeitweise fixiert ist. Die Teile 1 und 1a sind durch eine übliche Rastverbindung 26 miteinander lagesicher verbunden. Das vordere Ende der Sperrgliedstütze hat eine Abrundung 27 als verbesserte Arbeitsfläche für eine er­leichterte Bewegung des Sperrgliedes.Above the ejector 9 and behind the locking member 8, the locking member support 10 is arranged, axially at least substantially parallel to the direction of movement of the ejector, so that the support 10 moves forward when the tongue 4 is locked due to the compression spring 13 and when the release button 11 is pressed the arrow 25 moved back. As FIGS. 1 and 3 show, the support 10 engages at the rear approximately centrally on the locking member 8 and thus causes a locking moment on the locking member, since this is temporarily fixed in the region of its locking lug and during its unlocking time on an additional part 1a of the housing 1. Parts 1 and 1a are connected to one another in a positionally secure manner by means of a customary latching connection 26. The front end of the locking member support has a rounding 27 as an improved working surface for easier movement of the locking member.

Wie es besser aus Figur 5 zu erkennen ist, hat die Sperr­gliedstütze 10 zwei seitliche Arme 28 und 29, mit denen sie in länglichen Aussparungen 30 des gestrichelt ange­deuteten Gehäuseteiles 1a geführt ist, wie dem Fachmann ohne weitere Erläuterung klar ist.As can be seen better from FIG. 5, the locking member support 10 has two lateral arms 28 and 29, with which it is guided in elongated recesses 30 of the housing part 1a indicated by dashed lines, as is clear to the person skilled in the art without further explanation.

Vorzugsweise ist die eine Entriegelungsstellung darstellen­de, nach rückwärts geneigte Schräglage des Sperrgliedes 8 dadurch gesichert, daß das Sperrglied einerseits rück­ wärtig durch die Stütze 10 an einem erhöhten Bereich und andererseits durch eine vordere untere Anlage an dem Ge­häuseteil 1a und an dem Auswerfer 9 sowie durch eine obere Anlage der Sperrzapfen 19 an dem Oberrand der Langlöcher 18 gestützt ist.Preferably, the backward inclined position of the locking member 8, which represents an unlocking position, is secured in that the locking member on the one hand back is supported by the support 10 on an elevated area and on the other hand by a lower front contact on the housing part 1a and on the ejector 9 and by an upper contact of the locking pin 19 on the upper edge of the elongated holes 18.

Alternativ kann die Entriegelungsstellung des Sperr­gliedes auch dadurch gesichert sein, daß die seitlichen Langlöcher 18 für die Halterung und Führung der Zapfen des Sperrgliedes eine solche Länge aufweisen, daß an­stelle der hinteren Sperrgliedstütze 10 die hintere Be­grenzung der Langlöcher einerseits je einen hinteren Anschlag für die Zapfen bei Schräglage des ausgerasteten Sperrgliedes 8 bilden, und daß die Schräglage andererseits durch eine vordere untere Anlage an dem Gehäuseteil 1a und an dem Auswerfer 9 sowie in Verbindung mit der oberen Anlage der Sperrgliedzapfen an den Langlochrändern gege­ben ist.Alternatively, the unlocking position of the locking member can also be ensured in that the side elongated holes 18 for holding and guiding the pins of the locking member have such a length that instead of the rear locking member support 10, the rear limitation of the elongated holes on the one hand each has a rear stop for the pins Form inclined position of the disengaged locking member 8, and that the inclined position is given on the other hand by a front lower contact on the housing part 1a and on the ejector 9 and in connection with the upper contact of the locking member pins on the slot edges.

Die Langlöcher 18 in den Schenkeln 17 des Metallrahmens 7 sind vorzugsweise rechteckig ausgebildet. Sie können jedoch auch eine solche Form aufweisen, die sich nach hinten etwas erweitert. Es ist auch möglich, daß sich die Langlöcher 18 nicht exakt parallel zur Bewegungsrichtung der Zunge 4 des entsprechenden Gurtband-Endstückes 2 erstecken, sondern dazu eine etwas geneigte Richtung auf­weisen. Es muß jedoch gesichert sein, daß sich das Sperr­glied 8 in eine solche Schräglage bewegen läßt, aus wel­cher es sicher in seine Verriegelungsstellung gebracht werden kann.The elongated holes 18 in the legs 17 of the metal frame 7 are preferably rectangular. However, they can also have a shape that widens somewhat towards the rear. It is also possible that the elongated holes 18 do not extend exactly parallel to the direction of movement of the tongue 4 of the corresponding webbing end piece 2, but instead have a somewhat inclined direction. However, it must be ensured that the locking member 8 can be moved into such an inclined position from which it can be brought securely into its locking position.

Das beschriebene Gurtschloß funktioniert auf folgende Weise. Die beiden, voher zusammengesteckten Gurtband-­ Endstücke 2,3 werden in das übrige Schloß eingesteckt, wobei die Zunge 4 zunächst allein gegen den Auswerfer 9 zur Anlage kommt und diesen gegen die Federkraft 12 zurückschiebt. Dabei fällt das Sperrglied 8, unterstützt durch die Sperrgliedstütze 10, auf die Zunge 4. Sobald die Zunge 4 ihre Verriegelungsstellung erreicht, kommt das Steuerorgan 6 des Endstückes 3 gegen die Sperrnase 20 des Sperrgliedes 8 zur Anlage und bewirkt,daß das Sperrglied 8, bei weiterer Unterstützung durch die Stütze 10, in das Loch 23 des Rahmens 7 einklingt und gegen dessen Anschlag 24 zur Anlage kommt. Somit hat sich das Sperrglied 8 aus seiner Schräglage nach Figur 1 in seine Verriegelungsstellung nach Figur 2 bewegt. Aus dieser letzteren Stellung kann das Sperrglied selbsttätig nicht herausgelangen, weil es daran durch seine Zapfen 19, die am Oberrand der Langlöcher 18 anliegen, in Verbindung mit der Sperrgliedstütze 10 gehindert ist. Wird nun die Aus­lösetaste 11 in Richtung des Pfeiles 25 gedrückt (Figur 3), dann wird das Sperrglied 8 nach hinten gedrückt, wo­bei sich die Stütze 10 ebenfalls nach hinten gegen die Kraft der Feder 13 verschiebt, wodurch sich die Sperrnase 20 des Sperrgliedes 8 nach oben bewegt und somit die Zunge 4 des entsprechenden Endstückes wieder freigibt. Der Auswerfer 9 bewegt dann die Zunge 4 aus dem Schloß­mechanismus heraus und gelangt selbst in seine in den Figuren 1 und 3 gezeigte Ausgangsstellung, bei der sich auch das Sperrglied 8 auf dem Auswerfer 9 abstützt.The buckle described works in the following way. The two, previously put together webbing End pieces 2, 3 are inserted into the rest of the lock, the tongue 4 initially coming into contact solely with the ejector 9 and pushing it back against the spring force 12. The locking member 8, supported by the locking member support 10, falls on the tongue 4. As soon as the tongue 4 reaches its locking position, the control member 6 of the end piece 3 comes to bear against the locking lug 20 of the locking member 8 and causes the locking member 8 to further support by the support 10, in the hole 23 of the frame 7 and comes to rest against the stop 24. The locking member 8 has thus moved from its inclined position according to FIG. 1 into its locking position according to FIG. 2. The locking member cannot automatically get out of this latter position because it is prevented from doing so in connection with the locking member support 10 by its pins 19, which abut the upper edge of the elongated holes 18. If the release button 11 is now pressed in the direction of the arrow 25 (FIG. 3), the locking member 8 is pushed backwards, the support 10 also being moved rearward against the force of the spring 13, as a result of which the locking lug 20 of the locking member 8 moves forward moved up and thus the tongue 4 of the corresponding end piece releases again. The ejector 9 then moves the tongue 4 out of the lock mechanism and itself reaches its starting position shown in FIGS. 1 and 3, in which the locking member 8 is also supported on the ejector 9.
