Description

Die Erfindung betrifft einen Trapezgurt zum Kitesurfen, Windsurfen oder Segeln gemäß dem Oberbegriff des Patenanspruchs 1.The invention relates to a harness for kitesurfing, windsurfing or sailing according to the preamble of claim 1.

Derartige Trapezgurte können als Hüfttrapez oder als Sitztrapez ausgeführt sein und haben üblicher Weise einen Trapezhaken, der an einem Frontbügel oder einer Frontplatte befestigt ist. An dieser Frontplatte ist ein Hüftgurt mit einem gepolsterten Rückenteil angelascht, das im Bereich der Lendenwirbelsäule mit Pads Verstärkungen oder dergleichen versehen ist. Da beispielsweise beim Kitesurfen die über den Kite eingeleiteten Kräfte relativ stark in Vertikalrichtung wirken, ist es insbesondere bei Hüfttrapezen wichtig, dass diese gut sitzen. Dementsprechend muss das Trapez relativ straff an den Körper angelegt werden, um ein Verrutschen zu verhindern. Um dieses Anlegen zu vereinfachen, haben Trapeze üblicherweise einen Trapezverschluss, bei dem ein karabinerartiges Element in eine Öse eingehängt wird, wobei durch verstellbare Gurte zwischen der Platte bzw. dem Frontbügel und dem Rückenteil eine Anpassung an den Hüftumfang ermöglicht ist.Such harness belts can be designed as a waist harness or as a seat harness and usually have a harness hook that is attached to a front bracket or a front panel. A hip belt with a padded back part is attached to this front panel, which is provided with pads reinforcements or the like in the area of the lumbar spine. Since, for example, when kite surfing, the forces introduced via the kite act relatively strongly in the vertical direction, it is particularly important for waist harnesses that they fit well. Accordingly, the trapeze must be applied relatively tightly to the body to prevent it from slipping. In order to simplify this application, trapezoids usually have a trapezoid fastener in which a snap-hook element is hooked into an eyelet, with adjustable straps between the plate or the front bar and the back part making it possible to adapt to the waist circumference.

Problematisch dabei ist, dass der Karabiner mit relativ viel Kraft in die Öse eingehängt werden muss, um das exakte Anliegen des Trapezes an der Hüfte zu gewährleisten. Insbesondere problematisch ist auch das Lösen dieses Verschlusses, da zum Lösen des Karabiners entsprechend eine Vorspannung aufgebracht werden muss, um den Karabiner aushängen zu können.The problem here is that the carabiner has to be hooked into the eyelet with a relatively large amount of force in order to ensure that the trapeze fits exactly on the hip. The release of this lock is also particularly problematic, since in order to release the carabiner, a corresponding pretension must be applied in order to be able to unhook the carabiner.

In der DE 20 2004 006 143 U1 ist eine Lösung erläutert, bei der der Karabinerhaken über eine Federlasche an der Öse gesichert ist und mittels einer Handhabe aus seiner Verriegelungsposition in eine Freigabeposition bringbar ist. Konkret kann diese Handhabe als Zuglasche ausgeführt sein, über die der Surfer eine vergleichsweise große Kraft zum Lösen aufbringen kann.In the DE 20 2004 006 143 U1 a solution is explained in which the snap hook is secured to the eyelet by a spring clip and can be brought out of its locking position into a release position by means of a handle. Specifically, this handle can be designed as a pull strap, via which the surfer can apply a comparatively large amount of force to release it.

Problematisch ist jedoch auch bei dieser Variante, dass das Einhängen des Karabiners in die Öse immer noch schwierig ist, da zum Schließen die Hand zwischen den Karabiner und den Körper gebracht werden muss, um die erforderliche Zugkraft aufbringen zu können.The problem with this variant, however, is that it is still difficult to hang the carabiner in the eyelet, since the hand has to be placed between the carabiner and the body in order to be able to apply the required pulling force.

In der US 6,293,215 B1 ist ein Trapezgurt beschrieben, bei dem an den Endabschnitten einer Hakenplatte Ratschenhebel angeordnet sind, über die die Wirklänge von zahnriemenartigen Zugmitteln verstellbar ist. Dabei werden die Endabschnitte der Zahnriemen in einen Hohlraum der Hakenplatte 17 geführt. Eine derartige Lösung ist nur mit hohem fertigungstechnischen Aufwand realisierbar.In the US 6,293,215 B1 describes a trapeze belt in which ratchet levers are arranged on the end sections of a hook plate, via which the effective length of toothed belt-like traction means can be adjusted. The end sections of the toothed belts are guided into a hollow space in the hook plate 17 . A solution of this type can only be implemented with a great deal of manufacturing effort.

Viele Surfer lockern daher zum Anziehen die Gurtbänder, hängen dann den Trapezverschluss ein und ziehen danach wieder die Gurtbänder fest - diese Vorgehensweise ist sehr umständlich.Many surfers therefore loosen the straps to put them on, then attach the trapeze buckle and then tighten the straps again - this procedure is very cumbersome.

In der EP 2 834 309 A2 der Anmelderin wird zur Überwindung dieses Nachteils ein Trapezgurt beschrieben, bei dem ein mit einem ring- oder ösenförmigen Rückhalteelement verbindbares Schließstück eines Trapezverschlusses als Schwenkhebel ausgeführt ist, der um eine Schwenkachse schwenkbar gelagert ist. Dieser Schwenkhebel hat an einem ersten Endabschnitt einen Einhängehaken und beabstandet dazu einen Schließhaken, wobei die Schwenkachse im Abstand zum Einhängehaken ausgebildet ist. Beim Anlegen des Trapezgurtes wird das Rückhalteelement zunächst in den Einhängehaken eingehängt, wobei dieser Einhängevorgang sehr einfach ist, da der Trapezgurt locker sitzt. Durch Verschwenken des Schwenkhebels in seine Schließposition gelangt der Schließhaken in Wirkeingriff mit dem Rückhalteelement, wobei durch dieses Verschwenken die Wirklänge des Trapezverschlusses und damit der Umfang des Trapezgurtes verkürzt wird, so dass der Trapezgurt straff in der gewünschten Weise sitzt.In the EP 2 834 309 A2 To overcome this disadvantage, the applicant describes a trapeze belt in which a locking piece of a trapeze lock that can be connected to a ring-shaped or eyelet-shaped retaining element is designed as a pivoted lever that is pivoted about a pivot axis. This pivoting lever has a suspension hook on a first end section and a locking hook at a distance therefrom, the pivot axis being formed at a distance from the suspension hook. When putting on the trapeze belt, the restraining element is first hooked into the hanging hook, this hanging process being very simple since the harness belt is loose. By pivoting the pivoting lever into its closed position, the locking hook comes into operative engagement with the restraining element, this pivoting shortening the effective length of the trapeze lock and thus the circumference of the harness belt, so that the harness belt sits taut in the desired manner.

In der Praxis zeigte sich, dass ein derartiger Trapezgurt äußerst komfortabel anzulegen ist. Ein Nachteil aller beschriebener Lösungen besteht jedoch darin, dass die Anpassung des Trapezgurts an den Hüftumfang des jeweiligen Nutzers, der unter anderem vom Körperbau und von der getragenen Kleidung abhängt, sehr umständlich ist, da der oben beschriebene Trapezverschluss üblicherweise beidseitig über zwei Gurtbänder mit dem eigentlichen Hüft- oder Sitztrapez - im Folgende Trapezgurt genannt - verbunden ist und die Längenverstellung dieser Gurtbänder über Gurtbandspanner erfolgt, die sehr umständlich zu bedienen sind und des Weiteren häufig in einer Tasche des Trapezgurts aufgenommen sind, und somit sehr schwierig zugänglich und zu betätigen sind.Practice has shown that such a harness is extremely easy to put on. However, a disadvantage of all the solutions described is that the adjustment of the trapeze belt to the hip circumference of the respective user, which depends, among other things, on the physique and the clothing worn, is very cumbersome because the trapeze lock described above is usually connected on both sides via two straps to the actual hip or seat harness - referred to below as the trapeze belt - and the length of these straps is adjusted via strap tensioners, which are very cumbersome to use and are also often found in a pocket of the harness Harness belts are included, and are therefore very difficult to access and operate.

In der US 6,293,215 B1 ist eine Frontplatte mit einem Trapezhaken offenbart, wobei an den Endabschnitten der Hakenplatte verrastete Verriegelungselemente angebracht sind, die mit verzahnten Gurten zusammenwirken, deren von der Hakenplatte entfernter Endabschnitt am Hüftgurt befestigt ist. Der Verzahnungseingriff lässt sich durch betätigen einer hakenplattenseitigen Entriegelung lösen.In the US 6,293,215 B1 discloses a front panel with a harness hook, with snapped locking elements attached to the end portions of the hook plate, which interact with toothed straps, the end portion of which remote from the hook plate is fastened to the waist strap. The interlocking engagement can be released by pressing a release on the hook plate.

Nachteilig bei dieser Lösung ist, dass das Anlegen relativ umständlich ist, da die Gurtbänder jedes Mal in den Verriegelungsmechanismus eingeführt werden müssen.The disadvantage of this solution is that it is relatively difficult to put on, since the straps have to be inserted into the locking mechanism each time.

Dem gegenüber liegt der Erfindung die Aufgabe zugrunde, ein Trapezgurt mit verbesserter Handhabbarkeit zu schaffen.In contrast, the invention is based on the object of creating a trapeze belt with improved handling.

Diese Aufgabe wird durch einen Trapezgurt mit den Merkmalen des Patentanspruchs 1 gelöst.This problem is solved by a trapeze belt with the features of patent claim 1 .

Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject matter of the dependent claims.

Der erfindungsgemäße Trapezgurt, der beispielsweise als Hüft- oder Sitztrapez ausgeführt sein kann, hat Zugmittel, die jeweils über eine Verstelleinrichtung längenverstellbar mit einem Trapezverschluss verbunden sind. Dieser Trapezverschluss hat in an sich bekannter Weise ein Schließstück, das in Spanneingriff mit einem Rückhalteelement bringbar ist. Erfindungsgemäß sind die Verstelleinrichtungen und die Zugmittel nach Art einer Ratschenanordnung ausgebildet. Dies ist ein wesentlicher Unterschied zu dem eingangs beschriebenen Stand der Technik gemäß der US 6,293,215 B1 , bei der im Prinzip kein Trapezverschluss vorhanden ist und das oder die Gurtbänder lediglich in den Verriegelungsmechanismus eingeschoben werden. Bei der erfindungsgemäßen Lösung erfolgt das Einhängen in einfacher Weise mittels des Trapezverschlusses, wobei die Anpassung an den jeweiligen Hüftumfang über die Ratschenanordnung erfolgt.The harness according to the invention, which can be designed, for example, as a hip harness or seat harness, has traction means that are each connected to a harness fastener via an adjustment device in a length-adjustable manner. In a manner known per se, this trapezoidal closure has a locking piece which can be brought into clamping engagement with a retaining element. According to the invention, the adjusting devices and the traction means are designed in the manner of a ratchet arrangement. This is a major difference from the prior art described above according to the US 6,293,215 B1 , in which in principle there is no trapezoidal lock and the strap or straps only go into the locking mechanism be inserted. In the solution according to the invention, hanging is carried out in a simple manner by means of the trapezoidal lock, with the adjustment to the respective hip circumference taking place via the ratchet arrangement.

Ein weiterer Vorteil dieser Lösung gegenüber dem oben genannten Stand der Technik besteht darin, dass bei der erfindungsgemäßen Lösung die Hakenplatte sehr einfach aufgebaut werden kann, während bei der bekannten Lösung an der Hakenplatte beidseitig Verriegelungsmechanismen befestigt werden müssen, so dass diese einen komplexen Aufbau hat und zudem über eine Vielzahl von vorstehenden Bauelementen verfügt, die die Gefahr eines versehentlichen Lösens erhöhen.Another advantage of this solution compared to the above-mentioned prior art is that in the solution according to the invention the hook plate can be constructed very simply, while in the known solution locking mechanisms have to be attached to the hook plate on both sides, so that it has a complex structure and also has a large number of protruding components that increase the risk of accidental detachment.

Derartige Ratschenanordnungen erlauben es, die Wirklänge der Zugmittel sehr schnell einzustellen und dabei jedes Zugmittel individuell auf die gewünschte Wirklänge einzustellen. Aufgrund dieser sehr einfachen Verstellmöglichkeit kann unter Umständen auf einen relativ komplexen Mechanismus, wie er in der EP 2 835 309 A2 beschrieben ist verzichtet werden, da das Lösen und Spannen alleine über die Verstelleinrichtung erfolgt.Ratchet arrangements of this type allow the effective length of the traction means to be set very quickly and each traction means to be set individually to the desired effective length. Due to this very simple adjustment, a relatively complex mechanism, as shown in the EP 2 835 309 A2 described can be dispensed with, since the loosening and tightening takes place solely via the adjustment device.

Dabei kann es ausreichen, wenn die Verstelleinrichtungen lediglich schließstückseitig ausgebildet sind, so dass dieses durch Verstellen der Ratschenanordnungen in eine Einhängeposition und eine Schließposition (mit Vorspannung) gebracht werden kann.It can be sufficient if the adjusting devices are only formed on the closing piece side, so that this can be brought into a hanging position and a closed position (with pretension) by adjusting the ratchet arrangements.

Das Anlegen des Trapezgurtes ist besonders komfortabel, da dem Schließstück und dem von diesem entfernten Endabschnitt der Hakenplatte jeweils zwei Ratschenanordnungen mit zwei etwa parallel oder etwa V-förmig verlaufenden Zahnriemen zugeordnet sind, die am Schließstück bzw. an der Hakenplatte angreifen.The harness is particularly easy to put on because the closing piece and the end section of the hook plate remote from it are each assigned two ratchet arrangements with two approximately parallel or approximately V-shaped toothed belts which engage the closing piece or the hook plate.

Bei einem besonders bevorzugten Ausführungsbeispiel sind die Zugmittel als Zahnriemen ausgebildet, die entlang einer trapezgurtseitigen Führungsplatte geführt sind und an der ein Ratschenhebel schwenkbar gelagert ist, durch dessen Verschwenkung der Zahnriemen mit Bezug zur Führungsplatte verstellbar ist. Derartige Zahnriemen sind mit einer gewissen Biegesteifigkeit ausgeführt, die ein optimales Einleiten der Zugkraft in den Trapezgurt ermöglicht. Dies ist ein wesentlicher Vorteil gegenüber den herkömmlichen Gurtbändern, die biegeschlaff ausgeführt sind und keinerlei Eigensteifigkeit aufweisen, so dass die aufgebrachte Zugkraft nicht - wie bei der erfindungsgemäßen Lösung - eine definierte Richtung hat sondern eher von der Abstützung des Hüftgurts am Körper abhängt und somit keine definierte Verspannposition ermöglicht.In a particularly preferred embodiment, the traction means are designed as toothed belts, which are guided along a guide plate on the trapezium belt side and on which a ratchet lever is pivotably mounted, by pivoting the toothed belt being adjustable in relation to the guide plate. Such toothed belts are designed with a certain flexural rigidity that is optimal Introduction of the tensile force in the trapeze belt allows. This is a significant advantage over conventional belt straps, which are designed to be flexible and have no inherent rigidity, so that the applied tensile force does not have a defined direction—as in the solution according to the invention—but rather depends on the support of the hip belt on the body and is therefore not a defined one bracing position allows.

Bei einer bevorzugten Lösung ist die Ratschenanordnung mit einem Sperrelement ausgeführt, das eine Bewegung des Zahnriemens in Richtung Erhöhung der Spannung zulässt und in Gegenrichtung, d. h., in Richtung der Entlastung lösbar sperrt. Zum Entlasten wird dann dieses Sperrelement gelöst.In a preferred solution, the ratchet assembly is designed with a locking element that allows movement of the toothed belt in the direction of increasing tension and in the opposite direction, i. H. Releasably locks in the direction of relief. To relieve this blocking element is then released.

Das Einleiten der Zugkraft wird noch weiter optimiert, wenn das Schließstück zumindest zwei etwa parallele hakenförmige Klauen hat, die entsprechend ausgebildete Halteelemente des Schließstücks einhängbar sind.The introduction of the tensile force is further optimized if the closing piece has at least two approximately parallel hook-shaped claws that can be hooked into correspondingly designed holding elements of the closing piece.

Die Anmelderin behält sich vor, auf ein Schließstück mit zwei derartigen Klauen oder ähnlichen Befestigungsmitteln, einen eigenen unabhängigen Patentanspruch zu richten.The applicant reserves the right to direct its own independent patent claim to a closing piece with two such claws or similar fastening means.

Durch die Verwendung eines Schließstücks mit zwei beabstandeten Klauen ist ein Verdrehen des Schließstücks mit Bezug zu einer einen Trapezhaken haltenden Hakenplatte oder dergleichen zuverlässig verhindert, so dass die Krafteinleitung weiter optimiert ist. Diese Hakenplatte bildet dem entsprechend das Rückhalteelement aus. Dabei können in diesem Rückhalteelement Taschen ausgebildet sein, in die die hakenförmigen Klauen eintauchen und in Spanneingriff mit Haltebolzen oder dergleichen bringbar sind, so dass die Klauen nicht nach außen hin vorstehen.The use of a closing piece with two spaced claws reliably prevents the closing piece from twisting in relation to a hook plate or the like holding a harness hook, so that the introduction of force is further optimized. Accordingly, this hook plate forms the retaining element. In this case, pockets can be formed in this retaining element, into which the hook-shaped claws immerse and can be brought into clamping engagement with retaining bolts or the like, so that the claws do not protrude outwards.

Bei einer hochwertigen Lösung sind diese Klauen aus Metall oder einem faserverstärktem Kunststoff gebildet.In a high-quality solution, these claws are made of metal or a fiber-reinforced plastic.

Erfindungsgemäß wird es bevorzugt, wenn die Klauen etwa in Verlängerung der Zugmittel, insbesondere der Zahnriemen verlaufen.According to the invention, it is preferred if the claws run approximately as an extension of the traction means, in particular the toothed belt.

Für den Fall, dass es von Nutzern gewünscht wird, kann das Schließstück oder das Rückhalteelement wiederum mit einem Hebelmechanismus ausgebildet sein, der ein Spannen und Entspannen ohne Betätigung der Ratschenanordnung ermöglicht.In the event that it is desired by users, the striker or the retaining element can in turn be formed with a lever mechanism which allows for cocking and decocking without actuation of the ratchet assembly.

Das im Folgenden beschriebene Trapez kann als Hüfttrapez oder Sitztrapez ausgeführt sein und ist zum Kitesurfen, Windsurfen oder Segeln geeignet. Bei den folgenden Ausführungen wird ein Hüfttrapez - Trapezgurt genannt - beschrieben. Dieser Trapezgurt 1 hat gemäß der in Figur 1 dargestellten Draufsicht einen Hüftgurt 2 mit einem Rückenteil 4, das beispielsweise eine Versteifung aufweist, um die Kräfte am Rückenbereich zu verteilen. Das Rückenteil 4 ist dabei an die Anatomie des Rückens angepasst. Das Rückenteil 4 geht in zwei Seitenteile 6, 8 über, die wesentlich elastischer als das Rückenteil 4 ausgeführt sind und den Rumpf des Nutzers seitlich umschließen. In Verlängerung der Seitenteile 6, 8 können bauchseitige Frontlaschen 10, 12 vorgesehen sein, die beim Anlegen des Trapezgurtes mittels eines Klettverschlusses verbunden werden. An den beiden Seitenteilen 6, 8 ist eine Frontoder Hakenplatte 14 befestigt, die die beiden Frontlaschen 10, 12 überstreckt und an der ein Trapezhaken 16 befestigt ist. Beim dargestellten Ausführungsbeispiel ist die Hakenplatte 14 als Formstück aus Kunststoff ausgebildet, das flächig am Bauch anliegt.The trapeze described below can be designed as a waist harness or seat harness and is suitable for kitesurfing, windsurfing or sailing. In the following explanations, a hip harness—called a harness belt—is described. This harness belt 1 has according to in figure 1 shown plan view a hip belt 2 with a back part 4, which has, for example, a reinforcement to distribute the forces on the back area. The back part 4 is adapted to the anatomy of the back. The back part 4 merges into two side parts 6, 8, which are made much more elastic than the back part 4 and enclose the user's torso laterally. As an extension of the side parts 6, 8, front straps 10, 12 on the stomach side can be provided, which are connected by means of a Velcro fastener when the harness belt is put on. On the two side parts 6, 8, a front or hook plate 14 is attached, which stretches over the two front tabs 10, 12 and which a harness hook 16 is attached. In the illustrated embodiment, the hook plate 14 is designed as a molded piece made of plastic that rests flat on the abdomen.

Die Hakenplatte 14 ist einerseits über Zugmittel 20 und eine Verstelleinrichtung 22 mit dem Seitenteil 6 verbunden. Der in Figur 1 links liegende Endabschnitt der Hakenplatte 14 ist über einen Trapezverschluss 24 mit einem oder mehreren Zugmitteln 26 und einer weiteren Verstelleinrichtung 28 verbunden. Über die beiden Verstelleinrichtungen 22, 28 kann durch entsprechendes Verlängern oder Verkürzen der Zugmittel 20, 26 der Abstand der Hakenplatte 14 zu den Seitenteilen 6, 8 verändert werden, um eine Anpassung an den Hüftumfang des Nutzers zu ermöglichen.The hook plate 14 is connected to the side part 6 on the one hand via traction means 20 and an adjustment device 22 . the inside figure 1 The end section of the hook plate 14 lying on the left is connected to one or more traction means 26 and a further adjustment device 28 via a trapezoidal lock 24 . The distance between the hook plate 14 and the side parts 6, 8 can be changed via the two adjusting devices 22, 28 by correspondingly lengthening or shortening the traction means 20, 26 in order to enable an adjustment to the waist circumference of the user.

Wie im Folgenden noch näher erläutert wird, sind die Zugmittel 20, 26 und die Verstelleinrichtungen 22, 28 als Ratschenanordnung 30, 32 ausgebildet, die ein sehr schnelles und exaktes Verstellen ermöglichen.As will be explained in more detail below, the traction means 20, 26 and the adjusting devices 22, 28 are designed as a ratchet arrangement 30, 32, which enables very quick and precise adjustment.

Figur 2 zeigt eine Teildarstellung des Trapezgurts 1 mit dem Seitenteil 8, das über die Zugmittel 26 und die Verstelleinrichtung 28 sowie den Trapezverschluss 24 mit der Hakenplatte 14 verbindbar ist. figure 2 shows a partial representation of the trapeze belt 1 with the side part 8 which can be connected to the hook plate 14 via the traction means 26 and the adjusting device 28 as well as the trapeze lock 24 .

Demgemäß hat der Trapezverschluss 24 ein Schließstück 34, das mit zwei in etwa im Parallelabstand verlaufenden Klauen 36, 38 in ein Rückhalteelement 40 einsetzbar ist, das in die Hakenplatte 14 integriert ist. Bei dem in Figur 2 dargestellten Ausführungsbeispiel ist zusätzlich zu dem angedeuteten Trapezhaken 16 noch ein Trapeztampen 42 vorgesehen, der alternativ zum Trapezhaken 16 verwendet werden kann, um beispielsweise der Chicken-Loop mehr seitlichen Spielraum zu geben.Accordingly, the trapezoidal closure 24 has a closing piece 34 which, with two claws 36 , 38 running approximately at a parallel distance, can be inserted into a retaining element 40 which is integrated into the hook plate 14 . At the in figure 2 In the illustrated embodiment, a harness line 42 is provided in addition to the indicated harness hook 16, which can be used as an alternative to the harness hook 16, for example to give the chicken loop more lateral play.

Beim konkreten Ausführungsbeispiel greifen die beiden Klauen 36, 38 - wie im Folgenden noch näher erläutert wird - in zwei Ausnehmungen 44, 46 des Rückhalteelements 40 der Hakenplatte 14 ein, in denen jeweils ein Haltebolzen (siehe Figur 4) gelagert ist, der von der jeweiligen Klaue 36 bzw. 38 umgriffen ist. Die beiden Klauen 36, 38 sind an einem Basisteil 48 befestigt, das etwa bündig in eine gestufte Aufnahme 50 der Hakenplatte 14 eintaucht. Die Taschen 44, 46 münden jeweils in diese Aufnahme 50 ein, so dass weder die Klauen 36, 38 noch das Basisteil 48 nach vorne (weg vom Nutzer) hin auskragen. Am Basisteil 48 sind zwei als Zugmittel ausgeführte Zahnriemen 52, 54 befestigt. Diese sind aus einem vergleichsweise steifen, hochfesten Kunststoffmaterial ausgebildet und haben eine Vielzahl von Zähnen 56, die jeweils mit einer steilen und einer flacheren Zahnflanke ausgeführt sind. Die Zahnriemen 52, 54 sind dabei verschwenkbar und/oder verstellbar am Schließstück 34 gelagert, so dass sie sich in der dargestellten V-Relativposition an den jeweiligen Spannzustand anpassen können. Die Zahnriemen 52, 54 bilden gemeinsam mit Ratschenhebeln 58, 60 jeweils eine Ratschenanordnung 30, 31. Jeder der Ratschenhebel 58, 60 ist schwenkbar an einer am Seitenteil 8 befestigten Führungsplatte 62, 64 verbunden. An den schwenkgelenkseitigen Endabschnitten der Ratschenhebel 58, 60 ist jeweils eine Verzahnung 66, 68 ausgebildet, die ebenfalls eine Vielzahl von Zähnen mit einer steilen und einer flacheren Zahnflanke hat. Bei Verschwenken des Ratschenhebels 58, 60 um die jeweilige Schwenkachse 70, 72 wird der jeweilige Zahnriemen 52, 54 durch den Verzahnungseingriff im Bereich der steilen Zahnflanken in Richtung des Spanneingriffs transportiert, so dass entsprechend der Abstand zwischen dem jeweiligen Ratschenhebel 58, 60 und dem Schließstück 34 verkürzt wird. Zum Verlängern kann ein Entriegelungshebel 74, 76 betätigt werden, um den Verzahnungseingriff zu lösen, so dass die wirksame Länge des jeweiligen Zahnriemens 52, 54 wieder verlängert wird. Wie in Figur 2 dargestellt, verlaufen die beiden Zahnriemen 52, 54 etwa in Verlängerung der beiden Klauen 36, 38, so dass ein sehr homogener Kraftverlauf ohne in einer Verdrehung resultierende Querkräfte gewährleistet ist.In the specific exemplary embodiment, the two claws 36, 38 - as will be explained in more detail below - engage in two recesses 44, 46 in the retaining element 40 of the hook plate 14, in each of which a retaining bolt (see figure 4 ) is mounted, which is encompassed by the respective claw 36 or 38. The two claws 36, 38 are fastened to a base part 48 which dips into a stepped receptacle 50 of the hook plate 14 approximately flush. The pockets 44, 46 each open into this receptacle 50, so that neither the claws 36, 38 nor the base part 48 after cantilever out at the front (away from the user). Two toothed belts 52 , 54 designed as traction means are fastened to the base part 48 . These are made of a comparatively stiff, high-strength plastic material and have a large number of teeth 56, which are each designed with a steep and a flat tooth flank. The toothed belts 52, 54 are pivotably and/or adjustably mounted on the closing piece 34, so that they can adapt to the respective clamping state in the relative V position shown. The toothed belts 52, 54 together with ratchet levers 58, 60 each form a ratchet arrangement 30, 31. Each of the ratchet levers 58, 60 is pivotably connected to a guide plate 62, 64 fastened to the side part 8. At the end sections of the ratchet levers 58, 60 on the swivel joint side, toothing 66, 68 is formed, which likewise has a large number of teeth with a steep tooth flank and a flatter tooth flank. When the ratchet lever 58, 60 is pivoted about the respective pivot axis 70, 72, the respective toothed belt 52, 54 is transported in the direction of the clamping engagement by the toothing engagement in the area of the steep tooth flanks, so that the distance between the respective ratchet lever 58, 60 and the closing piece 34 is shortened. For lengthening, an unlocking lever 74, 76 can be actuated in order to release the toothed engagement, so that the effective length of the respective toothed belt 52, 54 is lengthened again. As in figure 2 shown, the two toothed belts 52, 54 run approximately as an extension of the two claws 36, 38, so that a very homogeneous course of force is ensured without transverse forces resulting in twisting.

Die beiden Ratschenhebel 58, 60 sind im Bereich ihrer Endabschnitte etwas nach oben gebogen, um ein einfaches Ergreifen zu gewährleisten. Eine versehentliche Verstellung in Öffnungsrichtung ist nur bei betätigten Entriegelungshebeln 74, 76 möglich, so dass ein versehentliches Lösen der Gurtspannung ausgeschlossen ist.The two ratchet levers 58, 60 are slightly bent upwards in the area of their end sections in order to ensure easy gripping. Accidental adjustment in the opening direction is only possible when the release levers 74, 76 are actuated, so that the belt tension cannot be released accidentally.

Figur 3 zeigt eine Teildarstellung des Bereichs des anderen Seitenteils 6, das einen entsprechenden Aufbau aufweist. figure 3 shows a partial view of the area of the other side part 6, which has a corresponding structure.

Auch auf dieser Seite ist eine Ratschenanordnung 32, 33 vorgesehen, um die Weite des Trapezgurts 1 zu verstellen.A ratchet arrangement 32, 33 is also provided on this side in order to adjust the width of the harness belt 1.

Dabei sind an dem vom Trapezverschluss 24 entfernten Endabschnitt der Hakenplatte 14 wiederum zwei Zahnriemen 78, 80 befestigt. Diese sind auch wieder etwa in der Zeichenebene verschwenkbar über Verbindungsschrauben 82, 84 oder sonstige Verbindungsmittel, wie Nieten oder dergleichen, an dem in Figur 3 sichtbaren Endabschnitt der Trapezplatte 14 angelenkt. Die Wirklänge der Zahnriemen kann dann wiederum über Ratschenhebel 84, 86 verstellt werden, die - wie die Ratschenanordnungen 30, 31 gemäß Figur 2 in Verzahnungseingriff mit der Verzahnung der Zahnriemen 78, 80 stehen. Die Verzahnung ist die Gleiche wie anhand Figur 2 beschrieben, so dass weitere Erläuterungen entbehrlich sind. Beide Ratschenhebel 84, 86 sind jeweils in einer am Seitenteil 6 befestigten Führungsplatte 88, 90 um ein Schwenklager 92, 94 verschwenkbar gelagert. Das Lösen erfolgt wiederum durch Betätigung eines Entriegelungshebels 96, 98.In this case, two toothed belts 78, 80 are in turn attached to the end section of the hook plate 14 remote from the trapezoidal closure 24. These can also be pivoted again approximately in the plane of the drawing via connecting screws 82, 84 or other connecting means, such as rivets or the like, on the figure 3 visible end portion of the trapezoidal plate 14 articulated. The effective length of the toothed belt can then in turn be adjusted via ratchet levers 84, 86 - like the ratchet assemblies 30, 31 according to figure 2 are in meshing engagement with the teeth of the toothed belts 78, 80. The gearing is the same as shown figure 2 described, so that further explanations are unnecessary. Both ratchet levers 84, 86 are each mounted in a guide plate 88, 90 attached to the side part 6 so as to be pivotable about a pivot bearing 92, 94. Release is in turn effected by actuating a release lever 96, 98.

Bei dem beschriebenen Ausführungsbeispiel wird im Bereich des Seitenteils 6 eine konstruktiv etwas anders gestaltete, jedoch funktional identische Ratschenanordnung 32, 33 wie am Seitenteil 8 verwendet.In the exemplary embodiment described, a ratchet arrangement 32 , 33 which is structurally somewhat different but functionally identical to that on the side part 8 is used in the area of the side part 6 .

Der Abstand der beiden Zahnriemen 78, 80 entspricht in etwa demjenigen der Zahnriemen 52, 54.The distance between the two toothed belts 78, 80 corresponds approximately to that of the toothed belts 52, 54.

Figur 4 zeigt das in Figur 2 dargestellte Seitenteil 8 mit gelösten Zahnriemen 52, 54 und geöffnetem Trapezverschluss 24. figure 4 shows that in figure 2 shown side part 8 with loosened toothed belt 52, 54 and open trapezoid lock 24.

Der Verzahnungseingriff der beiden Zahnriemen 52, 54 mit den Ratschenhebeln 58, 60 ist dabei durch Betätigen der Entriegelungshebel 74, 76 gelöst, so dass die Zahnriemen 52, 54 aus der Führungsplatte 62, 64 herausgezogen werden können. In der Darstellung gemäß Figur 4 sieht man recht deutlich das Basisteil 58, an dem einerseits die beiden Zahnriemen 52, 54 verschwenkbar und/oder verstellbar befestigt sind. Andererseits sind die beiden hakenförmigen Klauen 36, 38 angeordnet, die zur Hakenplatte 14 hin auskragen. An dem zugeordneten Endabschnitt der Hakenplatte 14 ist die Aufnahme 50 ausgebildet, deren Abmessungen in etwa denjenigen des Basisteils 48 entsprechen, so dass diese passgenau in die stufenförmige Aufnahme 50 eingesetzt werden kann. Die beiden Taschen 44, 46 münden in diese Aufnahme 50. In jeder der Taschen 44, 46 ist ein Haltebolzen 100, 102 vorgesehen, der bei geschlossenem Trapezverschluss 24 von den hakenförmigen Endabschnitten 104, 106 der Klauen 36, 38 umgriffen wird, wobei die Klauen 36, 38 passgenau in die Taschen 44, 46 eintauchen, so dass ein Verdrehen oder Kippen nicht möglich ist und die Zugkraft exakt in Verlängerung der Hakenplatte 14 verläuft.The toothed engagement of the two toothed belts 52, 54 with the ratchet levers 58, 60 is released by actuating the release lever 74, 76, so that the toothed belts 52, 54 can be pulled out of the guide plate 62, 64. In the representation according to figure 4 one sees quite clearly the base part 58 on which on the one hand the two toothed belts 52, 54 are fastened pivotably and/or adjustably. On the other hand, the two hook-shaped claws 36, 38 are arranged, which protrude towards the hook plate 14. The receptacle 50 is formed on the associated end section of the hook plate 14, the dimensions of which roughly correspond to those of the base part 48, so that it fits exactly into the stepped receptacle 50 can be used. The two pockets 44, 46 open into this receptacle 50. In each of the pockets 44, 46 there is a retaining bolt 100, 102 which, when the trapezoidal closure 24 is closed, is surrounded by the hook-shaped end sections 104, 106 of the claws 36, 38, the claws 36, 38 fit exactly into the pockets 44, 46, so that twisting or tipping is not possible and the tensile force runs exactly as an extension of the hook plate 14.

Dies ist anschaulich in Figur 5 dargestellt. Man erkennt, dass die beiden Klauen 36, 38 vollständig in die jeweilige Tasche 44, 46 eintauchen und das Basisteil 48 in der Aufnahme 50 aufgenommen ist und dabei bündig zur benachbarten Großfläche der Hakenplatte 14 verläuft. Die beiden Zahnriemen 52, 54 sind mit ihren an den Verbindungsschrauben 82, 83 befestigten Endabschnitten in eine entsprechende Ausnehmung 108 des Basisteils 48 eingesetzt, so dass auch hier kein oder nur ein unwesentlicher Überstand vorliegt.This is vividly in figure 5 shown. It can be seen that the two claws 36 , 38 dip completely into the respective pocket 44 , 46 and the base part 48 is accommodated in the receptacle 50 and runs flush with the adjacent large area of the hook plate 14 . The two toothed belts 52, 54 are inserted with their attached to the connecting screws 82, 83 end sections in a corresponding recess 108 of the base part 48, so that there is no or only an insignificant overhang.

Zum vollständigen Schließen des Trapezgurts 1 werden die beiden Zahnriemen 52, 54 in die jeweiligen Führungsplatten 62, 64 (letztere nicht sichtbar in Figur 5) eingeschoben und die Spannung dann durch Betätigen der Ratschenhebel 58, 60 aufgebaut. Durch den relativ engen Zahnabstand ist sehr exakte Einstellung der gewünschten Gurtspannung gewährleistet.To completely close the trapeze belt 1, the two toothed belts 52, 54 are pushed into the respective guide plates 62, 64 (the latter not visible in Fig figure 5 ) is inserted and the tension then built up by actuating the ratchet levers 58, 60. Due to the relatively narrow tooth spacing, very precise adjustment of the desired belt tension is guaranteed.

Bei der erfindungsgemäßen Ausführungsform ist - wie eingangs erläutert - kein Schwenkhebelmechanismus zum Öffnen und Schließen des Trapezverschlusses 24 erforderlich. Durch die individuelle Einstellung der Wirklänge der vier Zahnriemen 52, 54, 78, 80 ist eine exakte Anpassung an die jeweilige Anatomie möglich, wobei die Kraftübertragung durch die beiden im Abstand zueinander stehenden Klauen 36, 38 und die in Verlängerung von diesen ausgebildeten Zahnriemen 52, 54 und die weiteren Zahnriemen 78, 80 optimal ist, so dass ein exakter Sitz des Trapezgurtes 1 auch bei schwierigen Manövern gewährleistet ist. In Verbindung mit einem anatomisch ausgeformten, vorzugsweise relativ steifen Rückenteil 4 wird somit ein perfekter Sitz geschaffen, der auf einfache Weise an unterschiedliche Körperkonturen anpassbar ist.In the embodiment according to the invention - as explained above - no pivoting lever mechanism for opening and closing the trapezoidal closure 24 is required. By individually adjusting the effective length of the four toothed belts 52, 54, 78, 80, an exact adaptation to the respective anatomy is possible, with the power transmission taking place through the two spaced-apart claws 36, 38 and the toothed belts 52, 54 and the other toothed belts 78, 80 is optimal, so that an exact fit of the trapeze belt 1 is guaranteed even with difficult maneuvers. In conjunction with an anatomically shaped, preferably relatively stiff back part 4, a perfect fit is thus created which can be easily adapted to different body contours.

Offenbart ist ein Trapezgurt, bei dem die Verstellung mittels einer Ratschenanordnung erfolgt.A trapeze belt is disclosed in which the adjustment takes place by means of a ratchet arrangement.
