Description

Die Erfindung betrifft eine Zaunanlage mit im Abstand voneinander im Untergrund verankerten Pfosten und an den Pfosten gehaltenen Gitterwerken, wie Draht- oder Stabgitter.The invention relates to a fence system with posts anchored at a distance from one another in the ground and lattice works held on the posts, such as wire or bar grids.

Zaunanlagen dienen zur Einfriedung von Grundstücken und gleichzeitig zu ihrer Sicherung. Um den Sicherheits­effekt zu erhöhen, ist es bekannt, die Zaunanlage mit Alarmeinrichtungen auszurüsten, welche bei Erschütte­rungen des Zaunes oder bei Zerstörungen der Zaunfelder bzw. an diesen Feldern entlangverlaufender Spanndrähte ansprechen. Derartige Alarmeinrichtungen können auch so ausgebildet sein, daß in einer Zentrale der jeweilige Ort der Auslösung des Alarms ersichtlich ist. Das Ein­dringen in den durch die Zaunanlage eingefriedeten Bereich kann jedoch durch die Alarmanlage selbst nicht verhindert werden.Fence systems serve to enclose property and at the same time to secure it. In order to increase the security effect, it is known to equip the fence system with alarm devices which respond when the fence is shaken or when the fence fields are destroyed or tension wires running along these fields. Such alarm devices can also be designed so that the respective location of the triggering of the alarm can be seen in a control center. However, the alarm system itself cannot prevent the area from being fenced in by the fence system.

Erfahrungsgemäß werden zur Überwindung von Zaunanlagen bzw. zum Eindringen in die durch Zaunanlagen ge­sicherten Bereiche Kraftfahrzeuge verwendet, mit denen Personen und Gerätschaften in die Sicher­heitszone gebracht werden, um in die zu sichernden Objekte einzudringen oder diese zu zerstören.Experience has shown that overcoming fence systems or to penetrate into the areas secured by fence systems, with which people and equipment are brought into the security zone in order to penetrate into the objects to be secured or to destroy them.

Die in den Zaunanlagen vorgesehenen Durchfahrt­öffnungen sind in der Regel durch entsprechend widerstandsfähig ausgebildete Tore sowie auch in den Durchfahrten durch sog. Durchfahrtsperren ge­schützt, während der Zaun ein sehr leicht zu über­windendes Hindernis mit geringem Schutzwert dar­stellt.The passage openings provided in the fence systems are usually protected by gates with a correspondingly robust design and also in the passages by so-called passage barriers, while the fence represents an obstacle that is very easy to overcome and has a low protection value.

Der Erfindung liegt die Aufgabe zugrunde, eine Zaunanlage der beschriebenen Art so auszubilden, daß auch über große Längen des Zaunes eine Schutz­wirkung, ähnlich wie sie mittels der Tore oder Durchfahrtsperren erreichbar ist, erzielt wird.The invention has for its object to design a fence system of the type described so that a protective effect, similar to that which can be achieved by means of the gates or passage barriers, is achieved even over great lengths of the fence.

Gelöst wird vorstehende Aufgabe alternativ durch die im Anspruch 1 und Anspruch 6 gekennzeichneten Merkmale.The above object is alternatively achieved by the features characterized in claim 1 and claim 6.

Die neue Durchbruchsicherung des Zaunes läßt sich mit verhältnismäßig geringem Aufwand über lange Strecken erstellen und kann so ausgelegt werden, daß selbst mittelschwere Lastkraftwagen bei ihren im freien Gelände erreichbaren Geschwindigkeiten dieses Hindernis nicht überwinden können und im Falle des Versuchs eines Durchbruches beschädigt und mit größter Wahrscheinlichkeit auch fahrun­tüchtig werden.The new breakthrough protection of the fence can be created with relatively little effort over long distances and can be designed so that even medium-duty trucks cannot overcome this obstacle at their speeds achievable in open terrain and in the event of an attempt to break through it is damaged and most likely damaged become unable to drive.

In Verbindung mit den eingangs beschriebenen Alarm­anlagen, die entweder von dem Zaun oder von der Durchbruchsicherung ausgelöst werden können, ergibt sich ein besonders hoher Sicherheitswert der Zaun­anlage gegen ein Eindringen bei gleichzeitiger Anzeige des Ortes eines jeweiligen Eindringversuches.In connection with the alarm systems described above, either from the fence or from the Breakthrough protection can be triggered, there is a particularly high security value of the fence system against intrusion with simultaneous display of the location of a respective intrusion attempt.

Dadurch, daß die Durchbruchsicherung auf der dem Einfriedungsbereich zugekehrten Seite des Zaunes angeordnet ist, kann sie nur nach Überwindung des Zaunes selbst von Unberechtigten erreicht und ggf. außer Funktion gesetzt werden.Due to the fact that the breakthrough protection is arranged on the side of the fence facing the fencing area, it can only be reached by unauthorized persons after the fence itself has been overcome and may be deactivated.

Die Lastbegrenzungselemente und die Spannglieder sowie auch die Verankerungspfosten können dabei so bemessen werden, daß ein Bersten der Spannglieder bei einem Durchbruchversuch mit Sicherheit verhin­dert wird.The load limiting elements and the tendons as well as the anchoring posts can be dimensioned in such a way that the tendons will definitely not burst during an attempt to break through.

Sowohl durch die nach Anspruch 1 vorgesehenen elastisch verformbaren Lastbegrenzungselemente als auch mit den im Anspruch 6 genannten rohrför­migen, bleibend verformbaren Lastbegrenzungsele­menten wird eine Energie aufzehrende Wirkung und damit eine Bewegungsverzögerung des zum Durchbruch­versuch verwendeten Fahrzeuges und hierdurch die von den Spanngliedern nach der erfolgten Defor­mierung der Lastbegrenzungselemente allein auf­zunehmenden Kräfte vermindert. Die rohrförmigen, durch Zusammendrücken bleibend verformbaren Last­begrenzungselemente sind gegenüber den elastisch verformbaren Lastbegrenzungselementen nur einmal verwendbar, jedoch haben sie den großen Vorteil, daß sie wesentlich wirtschaftlicher herstellbar sind und leicht ersetzt werden können. Abgesehen davon wird es ohnehin bei einem Durchbruchversuch notwendig, die Zaunanlage zu reparieren, so daß der dann vorzunehmende Ersatz der Lastbegrenzungs­elemente ohne großen Aufwand leicht möglich ist.Both through the elastically deformable load limiting elements provided according to claim 1 and with the tubular, permanently deformable load limiting elements mentioned in claim 6, an energy-absorbing effect and thus a delay in movement of the vehicle used for the breakthrough attempt and thereby that of the tendons after the deformation of the load limiting elements alone has taken place forces to be absorbed. The tubular, permanently deformable load limiting elements can only be used once compared to the elastically deformable load limiting elements, but they have the great advantage that they are much more economical to manufacture and can be easily replaced. Apart from that, it will be necessary to repair the fence system anyway in the event of a breakthrough attempt the replacement of the load limiting elements that is then to be carried out is easily possible without great effort.

Die Verankerungspfosten der Durchbruchsicherung müssen nicht den gleichen Abstand wie die Zaun­pfosten haben. In der Regel genügt es, wenn die Verankerungspfosten in einem mehrfachen Abstand der Zaunpfosten angeordnet sind.The breakthrough anchorage posts need not be the same distance as the fence posts. As a rule, it is sufficient if the anchoring posts are arranged at a multiple distance from the fence posts.

Für Zaunanlagen mit elastisch verformbaren Begren­zungselementen sind weitere zweckmäßige Ausbil­dungsformen in den Unteransprüchen 3 bis 5 angegeben.For fence systems with elastically deformable limiting elements, further expedient forms of training are specified in subclaims 3 to 5.

Eine besonders zweckmäßige Ausgestaltung der Zaun­anlage mit rohrförmigen, bleibend verformbaren Lastbegrenzungselementen ist im Anspruch 7 genannt.A particularly expedient embodiment of the fence system with tubular, permanently deformable load limiting elements is mentioned in claim 7.

Unabhängig davon, ob elastisch verformbare oder bleibend verformbare Begrenzungselemente verwendet werden, empfiehlt es sich, die Spannglieder we­nigstens im Bereich der Enden als Spannseile aus­zubilden und zwischen diesen Enden und den an den Lastbegrenzungselementen anliegenden Widerlager­platten nach Art von Maulkupplungen ausgebildete Kupplungsteile vorzusehen, die über Zug- und Ab­standsbolzen mit den Widerlagerplatten verbunden sind. Dabei können die Zug- und Abstandsbolzen zweckmäßig als Spannbolzen mit Spannmuttern aus­gebildet sein. Bei Verwendung elastisch verform­barer Lastbegrenzungselemente können die Spann­bolzen und Spannmuttern gleichzeitig zur Vorspan­nung dieser Lastbegrenzungselemente dienen.Regardless of whether elastically deformable or permanently deformable limiting elements are used, it is advisable to design the tendons as tensioning ropes at least in the area of the ends and to provide coupling parts designed in the manner of jaw couplings between these ends and the abutment plates resting on the load limiting elements. and spacer bolts are connected to the abutment plates. The tension and spacer bolts can expediently be designed as clamping bolts with clamping nuts. When using elastically deformable load limiting elements, the clamping bolts and clamping nuts can simultaneously serve to preload these load limiting elements.

Weitere zweckmäßige Ausführungsformen für die beiden alternativen Lösungen nach den Ansprüchen 1 und 6 sind in den Unteransprüchen 10 bis 14 angegeben.Further expedient embodiments for the two alternative solutions according to claims 1 and 6 are specified in subclaims 10 to 14.

Die in den Figuren 1 und 2 wiedergegebene Zaunanlage weist in gleichem Abstand voneinander angeordnete Zaunpfosten 1 auf, die in dem dargestellten Beispiel als im Querschnitt dreieckförmige sich nach oben hin konisch verjüngende Hohlpfosten ausgeführt sind. An den Zaunpfosten 1 ist in bekannter Weise ein Gitter­werk 2 befestigt, welches sich über die gesamte Länge des Zaunes erstreckt. In dem dargestellten Beispiel ist das Gitterwerk 2 in Form eines Maschendrahtes ausgebildet.The fence system shown in FIGS. 1 and 2 has fence posts 1 which are arranged at the same distance from one another and, in the example shown, are designed as hollow posts which are triangular in cross-section and taper upwards. A lattice work 2 is attached to the fence post 1 in a known manner and extends over the entire length of the fence. In the example shown, the latticework 2 is in the form of a wire mesh.

Die Zaunpfosten 1 tragen an ihren oberen Enden Stachel­drahthalter 3, an denen als Übersteigsicherung Stachel­draht 4 in mehreren parallel zueinander verlaufenden Strängen gehalten ist.The fence posts 1 carry barbed wire holders 3 at their upper ends, on which barbed wire 4 is held in a plurality of strands running parallel to one another as a climbing protection.

Das Drahtgitter 2 ist auf der Außenseite der Zaunpfosten 1, d.h. auf der von dem Einfriedungsbereich abgewandten Seite befestigt.The wire mesh 2 is on the outside of the fence posts 1, i.e. attached on the side facing away from the enclosure area.

Auf der anderen, also dem Einfriedungsbereich zugekehr­ten, Seite des Zaunes bzw. der Pfosten 1 sind dem Zaun unmittelbar benachbart Verankerungspfosten 5 vorgesehen, die verhältnismäßig tief und fest in dem Untergrund gehalten sind, wie in der Fig. 1 durch die mit den Verankerungspfosten verbundenen Fundament­platten 5a angedeutet ist.On the other side of the fence, i.e. the side facing the fence or the post 1, the fence is provided directly with anchoring posts 5, which are held relatively deep and firmly in the ground, as in FIG. 1 by the foundation plates connected to the anchoring posts 5a is indicated.

Die Verankerungspfosten 5 sind jeweils paarweise dicht nebeneinander angeordnet. Zwischen den einander zugekehr­ten Verankerungspfosten 5 benachbarter Paare sind je­weils als Durchbruchsicherungen gegen Kraftfahrzeuge in dem dargestellten Beispiel zwei Spannglieder 6 und 6a gehalten, die bei der dargestellten Ausführung gemäß den Fig. 3 bis 6 als Spann- bzw. Stahlseile ausgeführt sind. Statt der Spannseile können auch über den überwiegenden Teil bzw. die gesamte Länge Stahlketten als Spannglieder vorgesehen sein.The anchoring posts 5 are each arranged in close proximity to one another in pairs. Between the mutually facing anchoring posts 5 of adjacent pairs, two tendons 6 and 6a are each held as breakdown safeguards against motor vehicles in the example shown, which are designed as tensioning or steel cables in the embodiment shown in FIGS. 3 to 6. Instead of the tensioning cables, steel chains can also be provided as tendons over the major part or the entire length.

Der Abstand der den jeweiligen Spanngliedern 6 bzw. 6a zugeordneten Verankerungspfosten 5 ist wesentlich größer als der Abstand zwischen benachbarten Zaunpfosten 1. In dem dargestellten Beispiel beträgt der Abstand der Verankerungspfosten 5 etwa das Fünffache des Abstan­des der Zaunpfosten 1.The distance between the anchoring posts 5 assigned to the respective tendons 6 or 6a is substantially greater than the distance between adjacent fence posts 1. In the example shown, the distance between the anchoring posts 5 is approximately five times the distance between the fence posts 1.

Die Verankerungspfosten 5 sind auch in ihrer Höhe wesentlich geringer bemessen als die Zaunpfosten 1. Sie ragen über den Untergrund nur so weit, daß die Spannglieder 6 bzw. 6a etwa in Achs- bis Chassishöhe üblicher Lastkraftwagen verlaufen, deren gewaltsames Eindringen in den von der Zaunanlage umschlossenen Einfriedungsbereich verhindert werden soll.The anchoring posts 5 are also dimensioned much smaller in height than the fence posts 1. They protrude above the ground only to such an extent that the tendons 6 and 6a run approximately at the height of the axle or chassis of conventional trucks, the violent penetration of which by the fence system enclosed enclosure should be prevented.

Wie besonders deutlich aus den Fig. 3 und 4 hervorgeht, stützen sich die Spannglieder 6 und 6a an den Zaun­pfosten 5 über Lastbegrenzungselemente 7 ab, die in dem dargestellten Beispiel innerhalb des Zaunpfostens 5 untergebracht sind. Die als Spannseile ausgebildeten Spannglieder 6 und 6a sind an ihren freien Enden mit Kauschen 8 ausgerüstet, welche in Kupplungsteile 9 eingreifen, die nach Art von Maulkupplungen ausgebildet sind und die einen Kupplungsbolzen 10 aufweisen, welcher sich durch den ösenförmigen Abschnitt der Kausche 8 hindurch erstreckt. Die Kupplungsteile 9 sind mit Zug- und Abstandsbolzen 10 verbunden, die sich durch den Verankerungspfosten 5 hindurch erstrecken sowie auch durch eine Widerlagerplatte 11 und an ihren freien Enden als Gewindebolzen zur Aufnahme von Spannmuttern 12 ausgebildet sind.As can be seen particularly clearly from FIGS. 3 and 4, the tendons 6 and 6a are supported on the fence posts 5 by means of load limiting elements 7, which are accommodated within the fence post 5 in the example shown. The tension members 6 and 6a designed as tensioning ropes are equipped at their free ends with thimbles 8 which engage in coupling parts 9 which are designed in the manner of jaw couplings and which have a coupling bolt 10 which extends through the eyelet-shaped section of the thimble 8. The coupling parts 9 are connected to tension and spacer bolts 10 which extend through the anchoring post 5 and are also formed by an abutment plate 11 and at their free ends as threaded bolts for receiving clamping nuts 12.

Die Lastbegrenzungselemente 7 stützen sich mit ihrem der Widerlagerplatte 11 abgekehrten Ende über eine Anlageplatte 11a auf der Innenseite der Wandung 5a des Verankerungspfostens 5 ab. Die Anlageplatte 11a kann dabei mit dem zugehörigen Lastbegrenzungselement 7 fest verbunden sein. Auch die Widerlagerplatte 11 kann gleichzeitig als Anlageplatte fest an dem Lastbe­grenzungselement 7 angeordnet sein.The load limiting elements 7 are supported with their end facing away from the abutment plate 11 via a contact plate 11a on the inside of the wall 5a of the anchoring post 5. The contact plate 11a can be firmly connected to the associated load limiting element 7. The abutment plate 11 can also be arranged at the same time as an abutment plate on the load limiting element 7.

Die Lastbegrenzungselemente 7 sind in dem dargestellten Beispiel als Puffer aus Zellkunststoff ausgebildet, die in ihren Abmessungen so gehalten sind, daß sie in dem von den Verankerungspfosten gebildeten Hohl­raum 5b in dem oberen Bereich dieser Pfosten geschützt aufgenommen werden können.The load limiting elements 7 are formed in the example shown as buffers made of cellular plastic, which are held in their dimensions so that they can be received in a protected manner in the cavity 5b formed by the anchoring posts in the upper region of these posts.

Zur Erzielung der notwendigen Stabilität der Veranke­rungspfosten 5 sind diese unter Verwendung von T- oder U-förmigen Profilteilen aufgebaut, wie dies in den Fig. 3 und 4 angedeutet ist.In order to achieve the necessary stability of the anchoring posts 5, they are constructed using T-shaped or U-shaped profile parts, as indicated in FIGS. 3 and 4.

Zum Schutz der über den jeweiligen Verankerungspfosten herausragenden Enden der Zug- und Abstandsbolzen 10 sowie der Spannmuttern 12 sowie auch für Revisionszwecke ist mit dem Verankerungspfosten 5 jeweils eine kasten­förmige Abdeckung 13 lösbar verbunden.A box-shaped cover 13 is detachably connected to the anchoring post 5 in order to protect the ends of the tension and spacer bolts 10 and the clamping nuts 12 projecting above the respective anchoring posts and also for revision purposes.

Die als Spannseile ausgebildeten Spannglieder 6 bzw. 6a sind längs der Zaunpfosten 1 an diesen geführt. Zu diesem Zweck sind die Zaunpfosten 1 gemäß Fig. 5 mit quer von den Zaunpfosten vorspringenden und höhen­einstellbar an den Pfosten gehaltenen Stützträgern 14 ausgerüstet. Die höheneinstellbare Befestigung der Stützträger 14 an den Zaunpfosten 1 erfolgt mittels schematisch dargestellter Schellen 15. An den freien Schenkeln der U-förmigen Stützträger 14, welche von dem Zaunpfosten 1 wegweisen, sind U-förmige Führungs­bügel 16 gehalten, durch die hindurch sich die Spann­seile 6 bzw. 6a mit geringem Bewegungsspiel erstrecken, so daß sie durch die genannten Bügel 16 nur in Längsrich­tung gleitend geführt sind. Auf diese Weise wird ein Durchhängen oder Herunterdrücken der Spannseile 6 bzw. 6a im Bereich zwischen den Verankerungspfosten 5 vermieden. Vielmehr werden die Spannglieder über ihre gesamte Länge in der jeweils gewünschten und eingestellten Höhe gehalten, um ihre Rammschutzwirkung auszuüben.The tendons 6 and 6a, which are designed as tensioning cables, are guided along the fence posts 1. For this purpose, the fence posts 1 according to FIG. 5 are equipped with support beams 14 which project transversely from the fence posts and are adjustable in height on the posts. The height-adjustable fastening of the support beams 14 to the fence posts 1 is carried out by means of schematically illustrated clamps 15. On the free legs of the U-shaped support beams 14, which point away from the fence posts 1, U-shaped guide brackets 16 are held, through which the tensioning cables 6 6a or 6a extend with little movement so that they are only slidably guided in the longitudinal direction by the mentioned bracket 16. In this way, sagging or pressing down of the tensioning ropes 6 and 6a in the area between the anchoring posts 5 is avoided. Rather, the tendons are held over their entire length in the desired and set height in order to exert their impact protection.

Die Fig. 6 und 7 zeigen eine andere Ausbildung der auf der Einfriedungsseite vorgesehenen Anordnung der eigentlichen Durchbruchsicherung, bestehend aus den Verankerungspfosten mit zugehörigen Spanngliedern und Lastbegrenzungselementen.6 and 7 show another embodiment of the arrangement of the actual breakthrough protection provided on the enclosure side, consisting of the anchoring posts with associated tendons and load limiting elements.

In den Fig. 6 und 7 sind die mit den Fig. 1 bis 5 übereinstimmenden Teile mit den gleichen Bezugszeichen versehen.6 and 7, the parts corresponding to FIGS. 1 to 5 are provided with the same reference numerals.

Die Anordnung nach den Fig. 6 und 7 weist statt der getrennten unmittelbar benachbart angeordneten Ver­ankerungspfosten 5 im Abstand der genannten Pfosten 5 angeordnete Verankerungspfosten 25 auf, die in dem dargestellten Beispiel aus einem Doppel-T-Profil be­stehen, an welchem beidseitig die Spannglieder 6 bzw. 6a über Kauschen 8 und Kupplungsteile 9 sowie Spann­schrauben 10 gehalten sind.The arrangement according to FIGS. 6 and 7 has instead of the separate anchoring posts 5 arranged directly adjacent to one another at a distance from the above-mentioned posts 5 anchoring posts 25 which, in the example shown, consist of a double-T profile, on which the tendons 6 and 6 on both sides 6a are held over thimbles 8 and coupling parts 9 and clamping screws 10.

An den freien Schenkeln des Doppel-T-Profiles des Pfostens 25 sind in dem dargestellten Beispiel haar­nadelförmige Zugschlaufen 26 befestigt, beispielsweise angeschweißt, welche die als rohrförmige, durch Zu­sammendrücken bleibend verformbaren Lastbegrenzungs­elemente 27 aufnehmen. Es handelt sich dabei um re­lativ kurze Rohrabschnitte, die sich lediglich über den Abstand erstrecken, der zwischen den Spannglie­dern 6 und 6a vorhanden ist, wobei der Durchmesser, die Wandstärke und auch das Material für die Rohr­abschnitte in Abhängigkeit von den aufzunehmenden Kräften bis zu ihrer bleibenden Verformung gewählt werden können.In the example shown, hairpin-shaped pull loops 26 are fastened, for example welded, to the free legs of the double-T profile of the post 25, which loops receive the load limiting elements 27 which are shaped as tubular and can be deformed by being compressed. These are relatively short pipe sections, which only extend over the distance between the tendons 6 and 6a, the diameter, the wall thickness and also the material for the pipe sections depending on the forces to be absorbed to their permanent Deformation can be selected.

Die Zug- und Abstandsbolzen 10 können sich durch die Schlaufen 26, die rohrförmigen Lastbegrenzungselemente 27 und durch die Widerlagerplatten 11 erstrecken, welche von Profilteilen 28 in dem Ausführungsbeispiel der Fig. 6 und 7 gebildet sind.The tension and spacer bolts 10 can extend through the loops 26, the tubular load limiting elements 27 and through the abutment plates 11, which are formed by profile parts 28 in the exemplary embodiment in FIGS. 6 and 7.

In der dargestellten Ausgestaltung erstrecken sich die Zug- und Abstandsbolzen 10 jedoch ober- bzw. unter­halb der Schlaufen 26 und rohrförmigen Lastbegrenzungs­elemente 27 nur durch die Widerlagerprofilteile 28, die an den rohrförmigen Lastbegrenzungselementen 27 befestigt, beispielsweise angeschweißt sind.In the illustrated embodiment, however, the tension and spacer bolts 10 extend above or below the loops 26 and tubular load limiting elements 27 only through the abutment profile parts 28 which are fastened, for example welded, to the tubular load limiting elements 27.

Die Spannglieder 6 und 6a der Anordnungen nach den Fig. 6 und 7 sind in gleicher Weise wie bei der Aus­führung der Zaunanlage nach den Fig. 1 bis 4 an den Zaunpfosten 1 geführt, wie dies in Fig. 5 dargestellt ist.The tendons 6 and 6a of the arrangements according to FIGS. 6 and 7 are guided in the same way as in the execution of the fence system according to FIGS. 1 to 4 on the fence post 1, as shown in FIG. 5.

Je nach Größe der bis zur bleibenden Verformung der rohrförmigen Lastbegrenzungselemente 27 aufzunehmenden Kräfte können die als Rohrabschnitte ausgebildeten Lastbegrenzungselemente in ihrem Durchmesser, der Wandstärke und auch durch die Materialwahl entspre­chend bemessen werden.Depending on the size of the forces to be absorbed until the tubular load limiting elements 27 are permanently deformed, the load limiting elements designed as tube sections can be dimensioned accordingly in terms of their diameter, the wall thickness and also by the choice of material.

Die Anordnung der rohrförmigen Lastbegrenzungsele­mente 27 in den Zugschlaufen 26 hat den Vorteil, daß die rohrförmigen Lastbegrenzungselemente 27 etwa über ihren halben Umfang zusätzlich abgestützt werden und hierdurch eine zusätzliche Stabilisierung gegen blei­bende Verformung erfahren.The arrangement of the tubular load-limiting elements 27 in the pull loops 26 has the advantage that the tubular load-limiting elements 27 are additionally supported over approximately half their circumference and thereby experience additional stabilization against permanent deformation.
