Description

Die Erfindung betrifft eine Schnallenanordnung für ein Gurtband nach dem Oberbegriff des Anspruchs 1.The invention relates to a buckle assembly for a webbing according to the preamble of claim 1.

Bei einer solchen Schnallenanordnung für ein Gurtband kann es sich beispielsweise um eine Schnallenanordnung für die Kinnbänder eines Skihelms oder eines Fahrradhelms handeln. Es kann sich bei der Schnallenanordnung aber auch beispielsweise um eine Schnallenanordnung für die Schulterriemen eines Rucksacks oder für die Bänder einer Schwimmweste handeln.Such a buckle assembly for a webbing may be, for example, a buckle assembly for the chin straps of a ski helmet or a bicycle helmet. However, the buckle arrangement can also be, for example, a buckle arrangement for the shoulder straps of a backpack or for the straps of a life jacket.

Eine derartige Schnallenanordnung für ein Gurtband umfasst einen Schnallenkörper, der mindestens einen Anlageabschnitt aufweist und mit mindestens einem Gurtband verbindbar ist, wobei in einem verbundenen Zustand mindestens eine erste Anlagepartie des mindestens einen Gurtbandes an dem mindestens einen Anlageabschnitt anliegt.Such a buckle assembly for a webbing comprises a buckle body which has at least one contact section and can be connected to at least one webbing, wherein in a connected state at least one first contact section of the at least one webbing rests against the at least one contact section.

Schnallenanordnungen der eingangs genannten Art sind in verschiedenen Ausführungsformen bekannt und können beispielsweise Doppel-D-Ringschnallen, Doppelstegschnallen, Dreistegschnallen, Leiterstegschnallen, Schiebeschnallen oder Klemmschnallen umfassen.Buckle assemblies of the type mentioned are known in various embodiments and may include, for example, double-D buckles, Doppelstegschnallen, Dreistegschnallen, Leiterstegschnallen, sliding buckles or buckles.

Häufig dienen derartige Schnallenanordnungen einer längenverstellbaren Fixierung einer Gurtbandanordnung. Dabei beruht die Fixierung der Gurtbandanordnung im Allgemeinen auf einer kraftschlüssigen Verbindung zwischen mindestens einer Gurtbandpartie und einem Abschnitt des Schnallenkörpers und/oder zwischen verschiedenen Gurtbandpartien im Bereich des Schnallenkörpers.Frequently, such buckle assemblies serve for a length-adjustable fixation of a webbing arrangement. The fixation of the webbing arrangement is generally based on a non-positive connection between at least one webbing part and a portion of the buckle body and / or between different webbing parts in the region of the buckle body.

Die Klemmwirkung, die der kraftschlüssigen Verbindung zugrunde liegt, ist bei vielen Schnallenanordnungen gerade dann besonders wirksam, wenn eine gerichtete Zugkraft auf mindestens ein Gurtbandende wirkt. Dementsprechend besteht häufig das Problem, dass bei einer unbelasteten Gurtbandanordnung, das heißt, in Abwesenheit von gerichteten Zugkräften auf mindestens ein Gurtbandende, die Längenfixierung einer Gurtbandanordnung durch die Schnallenanordnung nur unzuverlässig gewährleistet ist. So können sich beispielsweise die Kinnriemen eines Fahrradhelms, die anfänglich mittels einer Schnallenanordnung nicht ganz fest gezurrt werden, im Laufe der Zeit lösen. Dieser unerwünschte Effekt wird durch die Bewegung des Kinns, also durch unregelmäßige Zugkräfte auf die Riemen, noch verstärkt.The clamping effect, which is the basis of the non-positive connection, is particularly effective in many buckle assemblies, especially when a directed tensile force acts on at least one strap end. Accordingly, there is often the problem that with an unloaded webbing arrangement, that is, in the absence of directed tensile forces on at least one webbing end, the length fixation of a webbing arrangement by the buckle assembly is ensured only unreliable. For example, the chin straps of a bicycle helmet that are initially not lashed tightly by means of a buckle assembly may over time loosen. This undesirable effect is exacerbated by the movement of the chin, that is, by irregular pulling forces on the straps.

Bei einer aus der WO 2013/019610 A2 bekannten Schnallenanordnung ist eine Schlaufe an einem Gurtband angeordnet, um ein ungewolltes Verstellen des Gurtbandes zu verhindern. Die Schlaufe ist dabei separat von einem Schnallenkörper vorgesehen, was dazu führen kann, dass das - gewollte - Verstellen des Gurtbandes behindert und somit für einen Nutzer umständlicher wird.At one of the WO 2013/019610 A2 Known buckle assembly is a loop on a webbing arranged to prevent accidental adjustment of the webbing. The loop is provided separately from a buckle body, which can lead to the - intentional - obstructing the adjustment of the webbing and thus becomes more cumbersome for a user.

Aufgabe der vorliegenden Erfindung ist es, eine Schnallenanordnung für ein Gurtband zur Verfügung zu stellen, die eine zuverlässige längenverstellbare Fixierung einer Gurtbandanordnung auf eine einfache und kostengünstige Weise sicherstellt.Object of the present invention is to provide a buckle assembly for a webbing available, which ensures a reliable length-adjustable fixation of a webbing arrangement in a simple and cost-effective manner.

Diese Aufgabe wird durch eine Schnallenanordnung für ein Gurtband mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a buckle assembly for a webbing with the features of claim 1.

Demnach umfasst die Schnallenanordnung ferner eine an dem Schnallenkörper angeordnete Klemmschlaufe, die umfänglich geschlossen ist und eine Öffnung begrenzt. Die Klemmschlaufe ist derart an dem Anlageabschnitt um den Schnallenkörper herum angeordnet, dass der Schnallenkörper sich durch die Öffnung hindurch erstreckt. Die Klemmschlaufe ist zudem ausgebildet, die in verbundenem Zustand an dem Anlageabschnitt anliegende Anlagepartie mit einer Kraft in Richtung des mindestens einen Anlageabschnitts zu beaufschlagen.Accordingly, the buckle assembly further comprises a buckle disposed on the buckle body, which is closed circumferentially and defines an opening. The clamping loop is disposed on the abutment portion around the buckle body such that the buckle body extends through the opening. The clamping loop is also formed in the connected state to the Applying plant section adjacent plant section with a force in the direction of the at least one contact section.

Die Klemmschlaufe stellt in dem verbundenen Zustand des Schnallenkörpers und des mindestens einen Gurtbandes eine zusätzliche kraftschlüssige Verbindung zwischen einer Anlagepartie eines Gurtbandes und einem Anlageabschnitt des Schnallenkörpers bereit, die von gerichteten Zugkräften auf ein Gurtbandende unabhängig ist. Auf diese Weise kann das unerwünschte Lösen der Längenfixierung einer unbelasteten oder zeitweise unbelasteten Gurtbandanordnung ganz oder teilweise vermieden werden.The clamping loop provides in the connected state of the buckle body and the at least one webbing an additional frictional connection between a plant section of a webbing and a contact portion of the buckle body, which is independent of directed tensile forces on a Gurtbandende. In this way, the unwanted loosening of the length fixation of an unloaded or temporarily unloaded webbing arrangement can be completely or partially avoided.

Die Klemmschlaufe kann insbesondere die Gestalt eines umfänglich geschlossenen Rings, beispielsweise in Form eines sogenannten O-Rings, aufweisen. Die Klemmschlaufe ist vorzugsweise in sich flexibel verformbar und dabei weiter vorteilhafterweise längenelastisch, also entlang ihrer Umfangsrichtung dehnbar.The clamping loop may in particular have the shape of a circumferentially closed ring, for example in the form of a so-called O-ring. The clamping loop is preferably flexibly deformable in itself and furthermore advantageously elastic in length, that is to say it can be stretched along its circumferential direction.

In einer vorteilhaften Ausgestaltung der Erfindung kann die Klemmschlaufe elastisch ausgebildet sein. Insbesondere kann die Klemmschlaufe in dem verbundenen Zustand des Schnallenkörpers und des mindestens einen Gurtbandes elastisch vorgespannt sein. Die Kraft in Richtung des mindestens einen Anlageabschnitts wird dann ganz oder teilweise durch die elastische Vorspannung der Klemmschlaufe bewirkt.In an advantageous embodiment of the invention, the clamping loop can be designed to be elastic. In particular, the clamping loop may be resiliently biased in the connected state of the buckle body and the at least one webbing. The force in the direction of the at least one contact portion is then wholly or partially effected by the elastic bias of the clamping loop.

In einer Weiterbildung der Schnallenanordnung weist der Schnallenkörper mindestens eine Haltevorrichtung auf, die ausgebildet ist, zu verhindern, dass die Klemmschlaufe entlang einer Hauptbelastungsrichtung, in die eine Belastungskraft auf das mindestens eine Gurtband wirkt, von dem Schnallenkörper herabgleitet. So kann die Klemmschlaufe auf einfache Weise am Schnallenkörper im Bereich des Anlageabschnitts gehalten werden.In a further development of the buckle assembly, the buckle body has at least one holding device, which is designed to prevent the clamping loop from sliding down the buckle body along a main loading direction in which a loading force acts on the at least one webbing. Thus, the clamping loop can be easily held on the buckle body in the region of the contact section.

In einer Variante umfasst die Haltevorrichtung mindestens einen von dem Schnallenkörper vorspringenden Vorsprung, der die Klemmschlaufe in die Hauptbelastungsrichtung abstützt. Ein Herabgleiten der Klemmschlaufe von dem Schnallenkörper entlang der Hauptbelastungsrichtung kann auf diese Weise durch den Vorsprung verhindert werden.In one variant, the holding device comprises at least one protrusion projecting from the buckle body, which supports the clamping loop in the main loading direction. A sliding down of the clamping loop of the buckle body along the main loading direction can be prevented in this way by the projection.

In einer Ausführungsform ist die Klemmschlaufe stoffschlüssig mit dem Schnallenkörper verbunden. Beispielsweise kann ein Abschnitt der Klemmschlaufe mit einem Abschnitt des Schnallenkörpers verklebt oder verschweißt sein. Einem möglichen Verlust der Klemmschlaufe wird somit vorgebeugt.In one embodiment, the clamping loop is integrally connected to the buckle body. For example, a portion of the clamping loop with a section be glued or welded the buckle body. A possible loss of the clamping loop is thus prevented.

In einer weiteren Ausführungsform ist die Klemmschlaufe einstückig mit dem Schnallenkörper ausgebildet. Auf diese Weise kann ebenfalls ein Verlust der Klemmschlaufe vermieden werden, wobei die Herstellungskosten einer derart einstückig ausgebildeten Anordnung von Schnallenkörper und Klemmschlaufe in Folge weniger Montageschritte besonders günstig sein können.In a further embodiment, the clamping loop is formed integrally with the buckle body. In this way, a loss of the clamping loop can also be avoided, wherein the manufacturing cost of such an integrally formed arrangement of the buckle body and clamping loop in consequence of fewer assembly steps can be particularly favorable.

In einer Variante der erfindungsgemäßen Schnallenanordnung liegt in dem verbundenen Zustand mindestens eine zweite Anlagepartie des mindestens einen Gurtbandes oder eines anderen Gurtbandes an der mindestens einen ersten Anlagepartie an, wobei die mindestens eine zweite Anlagepartie von der Klemmschlaufe mit der Kraft in Richtung des mindestens einen Anlageabschnitts beaufschlagt wird. So kann eine kraftschlüssige Verbindung nicht nur zwischen dem Anlageabschnitt des Schnallenkörpers und der ersten Anlagepartie des Gurtbandes sondern, zudem zwischen der ersten Anlagepartie und der zweiten Anlagepartie geschaffen werden. Dementsprechend kann ein besonders starker Kraftschluss erzeugt werden, der einer unerwünschten Lockerung der Längenfixierung der Gurtbandanordnung wirksam entgegensteht.In a variant of the buckle assembly according to the invention, in the connected state, at least one second plant section of the at least one webbing or other webbing abuts against the at least one first planting section, the at least one second conditioning section being acted upon by the clamping loop with the force in the direction of the at least one contact section becomes. Thus, a non-positive connection can be created not only between the abutment portion of the buckle body and the first plant section of the webbing, but also between the first plant section and the second plant section. Accordingly, a particularly strong adhesion can be generated, which effectively counteracts an unwanted loosening of the length fixing of the webbing arrangement.

In diesem Fall ist das Gurtband beispielsweise um einen Steg des Schnallenkörpers herum geschlungen, so dass die erste Anlagepartie und die zweite Anlagepartie des Gurtbandes im Bereich des Anlageabschnitts des Schnallenkörpers zu liegen kommen und von der Klemmschlaufe kraftbeaufschlagt sind, um eine Reibung der Anlagepartien mit dem Anlageabschnitt zu vergrößern und auf diese Weise ein Verstellen der Anlagepartien zueinander - insbesondere auch in einem Zustand, in dem keine oder nur geringe Zugkräfte auf das Gurtband wirken - zu verhindern oder zumindest zu erschweren.In this case, the webbing is looped around a web of the buckle body, for example, so that the first contact part and the second contact part of the webbing come to lie in the area of the contact portion of the buckle body and are subjected to force by the clamping loop, in order to friction the contact parts with the contact portion To increase and in this way an adjustment of the plant sections to each other - especially in a state in which no or only low tensile forces acting on the webbing - to prevent or at least complicate.

In einer vorteilhaften Ausführungsform umfasst die Schnallenanordnung mindestens eine Doppel-D-Ringschnalle, Doppelstegschnalle, Dreistegschnalle, Leiterschnalle, Schiebeschnalle oder Klemmschnalle. Bei derartigen Schnallen tritt das eingangs beschriebene Problem der unerwünschten Lockerung der Längenfixierung eines Gurtbandes im unbelasteten Zustand häufig auf, so dass die erfindungsgemäße Schnallenanordnung hier besonders vorteilhafter Weise eingesetzt werden kann.In an advantageous embodiment, the buckle assembly comprises at least one double-D ring buckle, double-bar buckle, three-bar buckle, ladder buckle, sliding buckle or clamp buckle. In the case of such buckles, the problem of undesired loosening of the length fixing of a strap in the unloaded state described at the beginning occurs frequently, so that the buckle arrangement according to the invention can be used here in a particularly advantageous manner.

Das Gurtband ist vorzugsweise entlang seiner Längserstreckungsrichtung nicht elastisch ausgebildet. Das Gurtband kann beispielsweise aus einem Stoffgewebe oder auch aus Leder oder dergleichen gefertigt sein.The webbing is preferably not elastic along its longitudinal direction. The webbing may for example be made of a fabric or leather or the like.

Eine Schnallenanordnung der hier beschriebenen Art kann vorteilhafterweise an Rucksäcken, Taschen, Koffern oder Behältern anderer Art zum Einsatz kommen. Eine Schnallenanordnung der hier beschriebenen Art kann zudem an Helmen, insbesondere, Ski-, Fahrrad- oder Motoradhelmen oder überall dort, wo ein Verstellen eines Gurtbandes relativ zum Schnallenkörper verhindert werden soll, zum Einsatz kommen.A buckle assembly of the type described herein may advantageously be used on rucksacks, bags, suitcases or containers of other types. A buckle assembly of the type described here can also be used on helmets, especially, ski, bicycle or motorcycle helmets or wherever an adjustment of a webbing is to be prevented relative to the buckle body used.

Der der Erfindung zugrundeliegende Gedanke soll nachfolgend anhand der in den Figuren dargestellten Ausführungsbeispiele näher erläutert werden. Es zeigen:

Die Figuren 1A und 1B zeigen aus unterschiedlichen Perspektiven eine Schnallenanordnung 1 für ein Gurtband, wie sie auf vielfältige Weise zum Beispiel an einem Bekleidungsstück, einem Helm oder einer Tasche zum Einsatz kommen kann. Die Schnallenanordnung 1 umfasst einen Schnallenkörper 10, der ausgebildet ist, mit einem zweiten Schnallenkörper 11 in eine lösbare Rastverbindung gebracht zu werden.The Figures 1A and 1B show from different perspectives a buckle assembly 1 for a webbing, as it can come in many ways, for example on a piece of clothing, a helmet or a bag used. The buckle assembly 1 comprises a buckle body 10, which is designed to be brought with a second buckle body 11 in a releasable latching connection.

Der Schnallenkörper 10 ist mit einem Gurtband 2 verbunden. Dabei ist in von Stegschnallen bekannter Weise ein Gurtbandende 20 des Gurtbandes 2 um einen Steg 102 des Schnallenkörpers 10 geschlungen und entlang einer Richtung Z des Gurtbandes wieder aus dem Schnallenkörper 10 herausgeführt. Der Schnallenkörper 10 weist einen Anlageabschnitt 101 auf, an welchem in dem dargestellten verbundenen Zustand eine erste Anlagepartie 21 des Gurtbandes 2 anliegt.The buckle body 10 is connected to a webbing 2. In this case, a webbing end 20 of the webbing 2 is wrapped around a web 102 of the buckle body 10 in known manner by webbing buckles and led out of the buckle body 10 along a direction Z of the webbing. The buckle body 10 has an abutment portion 101 on which in the illustrated connected state a first abutment portion 21 of the webbing 2 is applied.

In einem entlasteten Zustandes 2, das heißt, wenn keine Zugkraft Z auf das Gurtband 2 wirkt, kann die Länge einer Gurtbandanordnung, die das Gurtband 2 umfasst, durch Schieben an dem Gurtband 2 und Ziehen an dem Gurtbandende 20 verstellt werden. In einem belasteten Zustand der Gurtbandanordnung, in dem eine Zugkraft Z auf das Gurtband 2 wirkt, verklemmen sich, wie in der Schnittdarstellung in Figur 1C zu erkennen, benachbarte erste und zweite Anlagepartien 21, 22 des Gurtbandes 2 derart aneinander und an dem Anlageabschnitt 101 des Schnallenkörpers 10, dass ein Verschieben gegeneinander und somit eine Längenverstellung der Gurtbandanordnung verhindert wird.In a unloaded state 2, that is, when no tensile force Z acts on the webbing 2, the length of a webbing assembly comprising the webbing 2 can be adjusted by pushing on the webbing 2 and pulling on the webbing end 20. In a loaded state of the webbing arrangement, in which a tensile force Z acts on the webbing 2, jam, as in the sectional view in Figure 1C to recognize, adjacent first and second bearing parts 21, 22 of the webbing 2 to each other and to the contact portion 101 of the buckle body 10 that a displacement against each other and thus a length adjustment of the webbing arrangement is prevented.

Dabei kann in anderen Ausführungsbeispielen das Gurtbandende 20 auch nach Art einer Zweisteg-, Dreisteg- oder Leiterschnalle um mehr als einen Steg 102 herumgeführt sein, um die wirkenden Reibungskräfte zu erhöhen und den Kraftschluss zu verstärken.In this case, in other embodiments, the strap end 20 may also be guided around more than one web 102 in the manner of a two-web, three-web or ladder buckle in order to increase the frictional forces acting and to reinforce the frictional connection.

Um einer unerwünschten Längenverstellung der Gurtbandanordnung im entlasteten Zustand entgegenzuwirken, ist an dem Schnallenkörper 10 eine Klemmschlaufe 13 angeordnet. Die Klemmschlaufe 13 ist umfänglich geschlossen und begrenzt eine Öffnung 130. Beispielsweise kann die Klemmschlaufe 13 ein umfänglich geschlossener flexibler Ring nach Art eines O-Rings sein.In order to counteract an undesirable length adjustment of the webbing arrangement in the unloaded state, a clamping loop 13 is arranged on the buckle body 10. The clamping loop 13 is circumferentially closed and defines an opening 130. For example, the clamping loop 13 may be a circumferentially closed flexible ring in the manner of an O-ring.

In dem dargestellten verbundenen Zustand erstreckt sich der Schnallenkörper 10 durch die Öffnung 130 hindurch, so dass die Klemmschlaufe 13 den Anlageabschnitt 101 des Schnallenkörpers 10 vollumfänglich umgreift.In the illustrated connected state, the buckle body 10 extends through the opening 130, so that the clamping loop 13 fully engages the contact portion 101 of the buckle body 10.

Das Gurtband 2, mit welchem der Schnallenkörper 10 verbunden ist, erstreckt sich gleichfalls durch die Klemmschlaufe 13 hindurch, so dass die Klemmschlaufe 13 insbesondere auch die erste und zweite Anlagepartie 21, 22 des Gurtbandes 2 vollumfänglich umgreift.The webbing 2, with which the buckle body 10 is connected, likewise extends through the clamping loop 13, so that the clamping loop 13 in particular also completely surrounds the first and second contact section 21, 22 of the webbing 2.

Die Klemmschlaufe 13 beaufschlagt die Anlagepartie 21 des Gurtbandes 2 mit einer Kraft K in Richtung des Anlageabschnitts 101. Zugleich beaufschlagt die Klemmschlaufe 13 die zweite Anlagepartie 22 des Gurtbandes, die an der ersten Anlagepartie 21 anliegt, mit einer Kraft K in Richtung des Anlageabschnitts 101 und in Richtung der ersten Anlagepartie 21.The clamping loop 13 acts on the contact section 21 of the webbing 2 with a force K in the direction of the contact section 101. At the same time, the clamping loop 13 acts on the second contact section 22 of the webbing, which bears against the first contact section 21, with a force K in the direction of the contact section 101 and in the direction of the first investment section 21.

Vorzugsweise ist die Klemmschlaufe 13 zu diesem Zweck elastisch ausgebildet. Beispielsweise kann die Klemmschlaufe 13 aus einem längenelastischen Material wie Silikon oder einem thermoplastischen Elastomer gefertigt sein.Preferably, the clamping loop 13 is designed to be elastic for this purpose. For example, the clamping loop 13 may be made of a length-elastic material such as silicone or a thermoplastic elastomer.

Insbesondere kann eine solche elastische Klemmschlaufe 13 in dem dargestellten verbundenen Zustand des Schnallenkörpers 10 und des mindestens einen Gurtbandes 2 elastisch vorgespannt sein. Eine elastische Vorspannung der Klemmschlaufe 13 kann beispielsweise bereits dadurch erzeugt werden, dass sich der Schnallenkörper 10 durch die Öffnung 130 der Klemmschlaufe 13 hindurch erstreckt Die Kraft K kann beispielsweise ganz oder teilweise durch die elastische Vorspannung der Klemmschlaufe 13 bewirkt werden.In particular, such an elastic clamping loop 13 may be elastically biased in the illustrated connected state of the buckle body 10 and the at least one webbing 2. An elastic prestress of the clamping loop 13 can already be generated, for example, by the fact that the buckle body 10 extends through the opening 130 of the clamping loop 13. The force K can, for example, be wholly or partly effected by the elastic prestressing of the clamping loop 13.

Durch die Kraft K werden die erste Anlagepartie 21 und die zweite Anlagepartie 22 des Gurtbandes 2 derart kraftschlüssig aneinander und/oder an dem Anlageabschnitt 101 des Schnallenkörpers 10 fixiert, dass auch im unbelasteten Zustand der Gurtbandanordnung, das heißt, bei Ausbleiben der Zugkraft Z (oder nur geringer Zugkraft Z) auf das Gurtband 2, eine unerwünschte Längenverstellung der Gurtbandanordnung ganz oder teilweise vermieden wird.By the force K, the first plant section 21 and the second plant section 22 of the webbing 2 are so non-positively fixed to each other and / or to the contact portion 101 of the buckle body 10 that even in the unloaded state of the webbing arrangement, that is, in the absence of tensile force Z (or only low tensile force Z) on the webbing 2, an unwanted length adjustment of the webbing arrangement is completely or partially avoided.

Wie anhand von Figur 1A erkennbar, weist der Schnallenkörper 10 als Haltevorrichtung 103 einen Vorsprung auf, der verhindert, dass die Klemmschlaufe 13 entlang einer Hauptbelastungsrichtung Z, in die die Zugkraft Z als Belastungskraft auf das mindestens eine Gurtband 2 wirkt, von dem Schnallenkörper 10 herabgleitet. Der Vorsprung stützt die Klemmschlaufe 13 in die Hauptbelastungsrichtung Z ab Ein Herabgleiten der Klemmschlaufe 13 von dem Schnallenkörper 10 entlang der Hauptbelastungsrichtung Z kann auf diese Weise durch den Vorsprung 103 verhindert werden.As based on Figure 1A recognizable, the buckle body 10 as a holding device 103 has a projection which prevents the clamping loop 13 along a main loading direction Z, in which the tensile force Z acts as a loading force on the at least one webbing 2, from the buckle body 10 slides down. The projection supports the clamping loop 13 in the main loading direction Z. A sliding down of the clamping loop 13 from the buckle body 10 along the main loading direction Z can be prevented in this way by the projection 103.

Es ist aber auch denkbar, dass die Haltevorrichtung 103 nicht als Vorsprung, sondern auf eine andere Weise, beispielsweise als Ausnehmung oder Nut, ausgebildet ist. Mit einer derartigen Haltevorrichtung 103 kann die Klemmschlaufe 13 auf einfache Weise im Bereich des Anlageabschnitts 101 an dem Schnallenkörper 10 gehalten werden.But it is also conceivable that the holding device 103 is not formed as a projection, but in another way, for example as a recess or groove. With such a holding device 103, the clamping loop 13 can be held in a simple manner in the region of the abutment portion 101 on the buckle body 10.

Um die bestimmungsgemäße Anordnung der Klemmschlaufe 13 an dem Schnallenkörper 10 jederzeit zu gewährleisten und um in einem demontierten Zustand der Schnallenanordnung 1 einen Verlust der Klemmschlaufe 13 vorzubeugen, kann es vorteilhaft sein, die Klemmschlaufe 13 stoffschlüssig mit dem Schnallenkörper 10 zu verbinden. Beispielsweise kann die Klemmschlaufe 13 mit einem seitlichen Abschnitt des Schnallenkörpers 10 verklebt oder verschweißt sein.In order to ensure the proper arrangement of the clamping loop 13 on the buckle body 10 at any time and to prevent loss of the clamping loop 13 in a disassembled state of the buckle assembly 1, it may be advantageous to connect the clamping loop 13 cohesively with the buckle body 10. For example, the clamping loop 13 may be glued or welded to a lateral portion of the buckle body 10.

In einer Variante kann die Klemmschlaufe 13 aber auch einstückig mit dem Schnallenkörper 10 ausgebildet sein. Dies kann den Vorteil einer besonders einfachen und kostengünstigen Montage der Schnallenanordnung 1 mit sich bringen.In a variant, the clamping loop 13 may also be formed integrally with the buckle body 10. This can bring the advantage of a particularly simple and cost-effective installation of the buckle assembly 1 with it.
