Die Erfindung betrifft ein Fahrzeug-Rückhaltesystem zur Anbringung an Verkehrswegen.The invention relates to a vehicle restraint system for attachment to traffic routes.
Aus der auf die Anmelderin der vorliegenden Erfindung zurückgehenden schweizerischen Patentschrift
Andere Schutzeinrichtungen des Stands der Technik bilden bei einem Anprall eines Fahrzeuges eine Tasche aus, in der sich das Fahrzeug verfängt und im Anschluss schleudernd und unkontrolliert zurück auf die Fahrbahn gelangt.Other protective devices of the prior art form in the event of a collision of a vehicle, a pocket in which the vehicle catches and then comes hurling and uncontrolled back on the road.
Es ist Aufgabe der vorliegenden Erfindung, ein Fahrzeug-Rückhaltesystem zur Anbringung an Verkehrswegen, mit mehreren in Fahrtrichtung hintereinander angeordneten Pfosten, mit mindestens einem Längsprofil und mindestens einer dem Verkehrsweg zugewandten Wandfläche, gebildet von zumindest einem Wandelement, wobei im Kraftfluss zwischen dem mindestens einen Wandelement und den Pfosten mindestens ein Dämpfungselement und das mindestens eine Längsprofil angeordnet sind, so weiterzubilden, dass es im Falle eines seitlichen Anpralls einen erheblichen Teil der kinetischen Anprallenergie absorbiert und das Fahrzeug in Fahrtrichtung auf den Verkehrsweg zurückführt.It is an object of the present invention, a vehicle restraint system for attachment to traffic routes, with several in the direction of travel successively arranged posts, with at least one longitudinal profile and at least one traffic route facing wall surface, formed by at least one wall element, wherein in the power flow between the at least one wall element and the post at least one damping element and the at least one longitudinal profile are arranged, so educate that it absorbs a significant portion of the kinetic impact energy in the event of a side impact and the vehicle in the direction of travel leads back to the traffic route.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 dadurch gelöst, dass das mindestens eine Dämpfungselement unmittelbar an den jeweiligen Pfosten und das Längsprofil zwischen dem mindestens einen Wandelement und dem mindestens einen Dämpfungselement angeordnet ist.This object is achieved by the characterizing features of claim 1, characterized in that the at least one damping element is arranged directly on the respective post and the longitudinal profile between the at least one wall element and the at least one damping element.
Hierdurch wird erreicht, dass bezüglich der Krafteinleitung in das System des Fahrzeug-Rückhaltesystems ein direkter Bezug zwischen dem jeweiligen Dämpfungselement und dem jeweiligen Pfosten gewährleistet werden kann. Die Pfosten stellen die stabile Rückhaltefunktion bereit und sind für anprallende Fahrzeuge ein besonders robuster Rückhaltewiderstand, der ein Durchbrechen der Schutzeinrichtung verhindern kann. Aufgrund der den Pfosten vorgelagerteh Bauteile, wie z.B. die Dämpfungselemente und das Wandelement, wird die Kraft des anprallenden Fahrzeugs verteilt, so dass der Widerstand der Pfosten nicht punktuell sondern über eine breite Fläche verteilt auf das Fahrzeug verlangsamend und gleichzeitig führend wirken kann.This ensures that with respect to the introduction of force into the system of the vehicle restraint system, a direct relationship between the respective damping element and the respective post can be ensured. The posts provide the sturdy restraint function and are a particularly robust restraining resistor for impacting vehicles that break prevent the protective device. Due to the upstream of the post components, such as the damping elements and the wall element, the force of the impacting vehicle is distributed so that the resistance of the posts not punctiform but distributed over a wide area on the vehicle slowing and at the same time can lead.
Die Erfindung schließt die allgemeine technische Lehre mit ein, dass das zumindest einen Teil einer Anprallfläche bildende Wandelement des passiven Fahrzeug-Rückhaltesystems frei schwenkbar gehalten ist, wobei durch diese vorteilhafte Ausführung eine besonders gleichmäßige Dämpfung des anprallenden Fahrzeugs erfolgt und eine Verkantung von innen liegenden Elementen der Schutzeinrichtung verhindert werden kann.The invention includes the general technical teaching that the at least part of an impact surface forming wall element of the passive vehicle restraint system is held freely pivotable, which is carried out by this advantageous embodiment, a particularly uniform damping of the impacting vehicle and a canting of internal elements of the Protective device can be prevented.
Auch ist Teil der technischen Lehre der Erfindung, dass die Wandfläche, d.h. die zum Verkehrsweg weisende Fläche des passiven Fahrzeug-Rückhaltesystems gegenüber einer senkrechten Ebene in Richtung des Verkehrswegs nach vorne geneigt ist. Hierdurch kann die positive Wirkung der Erfindung, anprallende Fahrzeuge auf ihrer Fahrseite zurückzuhalten und ein Abheben oder Überspringen der Schutzeinrichtung zu verhindern, verstärkt werden.Also part of the technical teaching of the invention is that the wall surface, i. the traffic-route facing surface of the passive vehicle restraint system is inclined forward relative to a vertical plane in the direction of the traffic route. This can enhance the positive effect of the invention of restraining impacting vehicles on their drive side and preventing the guard from being lifted or skipped.
Vorteilhafterweise können bei der Erfindung an jedem Pfosten jeweils zwei übereinander angeordnete und vertikal beabstandete Dämpfungselemente angeordnet sein, um die teilweise erhebliche kinetische Anprallenergie (Ekin=0,5*mv2) wirkungsvoll in Verformungsenergie und Wärme umzuwandeln. Dabei kann die Ausbildung der Dämpfungselemente durch der Wandstärke oder Auswahl spezifischer Materialien an individuelle Anforderungen angepasst und die Dämpfungscharaktetistik eingestellt werden. In einer bevorzugten Ausführungsform sind die Dämpfungselemente rohrförmig ausgebildet und innerhalb der Schutzeinrichtung liegend angeordnet, so dass die jeweilige Rohröffnung am oberen bzw. unteren Ende der Dämpfungselemente in Fahrtrichtung ausgerichtet ist.Advantageously, in each case two superimposed and vertically spaced damping elements can be arranged in the invention on each post, in order to effectively convert the partially considerable kinetic impact energy (E kin = 0.5 * mv 2 ) into deformation energy and heat. The design of the damping elements can be adapted to individual requirements by the wall thickness or selection of specific materials and the damping characteristics can be adjusted. In a preferred embodiment, the damping elements are tubular and arranged lying within the protective device, so that the respective pipe opening is aligned at the upper or lower end of the damping elements in the direction of travel.
Es ist günstig, dass sich die Dämpfungselemente in Fahrtrichtung beidseitig über die Breite des jeweiligen Pfostens hinaus erstrecken können, um einen Anprall und ein Verhaken des Fahrzeugs an der Pfostenkante bzw. eine Taschenblldung der Schutzeinrichtung zu vermeiden Es ist jedoch nicht ausgeschlossen, dass die Breite der Dämpfungselemente mit der Breite der Pfosten übereinstimmt bzw. die Dämpfungselemente schmaler ausgebildet sind als die Pfosten, wenn die Anforderung an die Schutzeinrichtung dies erfordert.It is favorable that the damping elements can extend in the direction of travel on both sides beyond the width of the respective post in order to avoid a collision and entanglement of the vehicle at the post edge or a pocket of the protective device. However, it is not excluded that the width of the Damping elements coincides with the width of the post or the damping elements are formed narrower than the posts, if the request for the protection device requires it.
In einer bevorzugten Ausführungsform verlaufen entlang des Verkehrswegs jeweils Längsprofile auf Höhe der Dämpfungselemente über eine Länge von mindestens zwei Pfosten, bevor sie mit den daran anschließenden Längsprofilen verbunden sind. Auf diese Weise kann die Anprallenergie insbesondere bei einem schrägen Anprall auf mehrere Pfosten und somit auch mehrere Dämpfungselemente verteilt werden, wobei durch die Längsprofile eine Übertragungswirkung realisiert werden kann. Günstig ist, dass die Längsprofile als C-Profil ausgebildet sein können, so dass sie leicht montierbar und ggf. auch leicht austauschbar sind. Die Anordnung der Längsprofile ist dahingehend günstig, dass neben der Dämpfung des Anpralls gleichzeitig eine Führung zurück in Fahrtrichtung und entlang der Schutzeinrichtung im Bereich der Dämpfungselemente erfolgen und eine Taschenbildung sicher vermieden werden kann.In a preferred embodiment, longitudinal profiles each extend along the traffic route at the level of the damping elements over a length of at least two posts, before they are connected to the adjoining longitudinal profiles. In this way, the impact energy can be distributed in particular in an oblique impact on a plurality of posts and thus also a plurality of damping elements, wherein a transfer effect can be realized by the longitudinal profiles. It is favorable that the longitudinal profiles can be formed as C-profile, so that they are easy to install and possibly also easily replaceable. The arrangement of the longitudinal profiles is favorable to the effect that in addition to the damping of the impact at the same time a guide back in the direction of travel and along the protective device in the region of the damping elements and a pocket formation can be safely avoided.
Vorteilhafterweise können Verformungsfüllelemente zwischen den Längsprofilen und den Dämpfungselementen und/oder zwischen den Dämpfungselementen und den jeweiligen Pfosten angeordnet sein, mit deren Hilfe eine genau vorbestimmte Verformungscharakteristik bezüglich der Art und Weise der Deformation der Dämpfungselemente ermöglicht werden kann. Günstig ist hierbei, wenn die Verformungsfüllelemente so angeordnet sind, dass die Krafteinleitung in das jeweils zugehörige Dämpfungselement im Falle eines Anpralls im wesentlichen in der Mitte der oberen und/oder unteren Hälfte des Dämpfungselements erfolgt. Durch die spezielle Positionierung der Verformungsfüllelemente und deren Kontaktpunkt zu den Dämpfungselementen ist die besonders bevorzugte stärkere Verformung im Mittelbereich gegenüber dem in Vertikalrichtung oberen und unteren Randbereich des Dämpfungselements, die nach einem Anprall zumeist jeweils eine Schleifenform aufweisen, realisierbar. Durch die Verformungstollelemente ist eine Einleitung eines großen Teils des Kraftflusses in vorbestimmter Lage möglich, der verbleibende Anteil kann direkt in das Dämpfungselement eingeleitet werden.Advantageously, deformation filling elements can be arranged between the longitudinal profiles and the damping elements and / or between the damping elements and the respective posts, with the aid of which a precisely predetermined deformation characteristic with respect to the manner of Deformation of the damping elements can be made possible. It is favorable in this case if the deformation filling elements are arranged so that the introduction of force into the respectively associated damping element takes place in the event of an impact substantially in the middle of the upper and / or lower half of the damping element. Due to the special positioning of the deformation filling elements and their point of contact with the damping elements, the particularly preferred greater deformation in the middle region can be achieved compared to the upper and lower edge regions of the damping element in the vertical direction, which generally have a loop shape after an impact. Due to the Verformstollelemente is an introduction of a large part of the Force flow in a predetermined position possible, the remaining portion can be introduced directly into the damping element.
Ein weiterer Teil der technischen Lehre der Erfindung beinhaltet, dass mindestens ein, aber auch mehrere Dämpfungselemente mit dem zugehörigen Verformungsfüllelementen als eine Baueinheit ausgebildet und am Pfosten befestigbar sein können. Es ist günstig, dass derartige Baueinheiten unabhängig von der Konstruktion der Schutzeinrichtung vorgefertigt und erst an der Baustelle als komplette Einheit angebracht werden können. Auch nach einer Zerstörung können somit derartige Baueinheiten leicht und kostengünstig ersetzt werden. In einer bevorzugten Ausführung ist die Baueinheit als eine Rahmenkonstruktion ausgebildet, welche sowohl die einzelnen Dämpfungselemente als auch die jeweils zugehörigen Verformungsfüllelemente trägt.Another part of the technical teaching of the invention includes that at least one, but also a plurality of damping elements can be formed with the associated Verformungsfüllelementen as a structural unit and fastened to the post. It is favorable that such units can be prefabricated independently of the construction of the protective device and can only be attached to the construction site as a complete unit. Even after destruction, such assemblies can thus be easily and inexpensively replaced. In a preferred embodiment, the structural unit is designed as a frame construction, which carries both the individual damping elements and the respectively associated deformation filling elements.
Das mindestens eine Wandelement kann an zumindest einem der Längsprofile und das Längsprofil wiederum an der Baueinheit der Rahmenkonstruktion bzw. der Baueinheit von Dämpfungselement und Verformungsfüllelementen befestigbar sein. Auf diese Weise kann ein Verschieben des Wandelements gegenüber der Längsprofile vermieden und bezüglich der Krafteinleitung auf die Schutzeinrichtung eine direkte Verbindung von Wandelement zu den Längsprofilen und somit den Dämpfungselementen sicher gewährleistet werden.The at least one wall element can in turn be fastened to at least one of the longitudinal profiles and the longitudinal profile can in turn be fastened to the structural unit of the frame construction or the assembly of damping element and deformation filling elements. In this way, a displacement of the wall element relative to the longitudinal profiles can be avoided and with respect to the application of force to the protective device, a direct connection of the wall element to the longitudinal profiles and thus the damping elements can be reliably ensured.
Wie oben bereits beschrieben, ist ein Auffahren des Fahrzeugs auf die Schutzeinrichtung bzw. im Extremfall sogar ein Abheben oder Überspringen der Schutzeinrichtung in jedem Falle zu verhindern. Die Schutzeinrichtung ist deshalb im oberen Bereich steifer ausgebildet als im unteren Bereich des Wandelements und der Dämpfungselemente. Dies kann dadurch erreicht werden, dass im oberen Bereich der Pfosten oberhalb des Wandelements mindestens ein sich in Fahrtrichtung erstreckendes Versteifungsprofil angeordnet ist, wobei als Versteifungsprofile vorzugsweise zwei übereinander angeordnete und miteinander und an den Pfosten befestigte Kastenprofile verwendet werden. Durch eine derartige Befestigung kann durch die Kastenprofile die Wirkung eines Doppel-T-Trägers realisiert und somit eine enorm hohe Steifigkeit und Führung für anprallende Fahrzeuge in Längsrichtung (Fahrtrichtung) gewährleistet werden. In einer bevorzugten Ausführung kann das Wandelement an dem unterem Kastenprofil unmittelbar oder mittelbar befestigt und/oder schwenkbar gehalten sein, so dass sich der Drehpunkt im Bereich des Kastenprofils befindet.As already described above, a drive-up of the vehicle on the protective device or in extreme cases, even a lifting or skipping the guard in any case to prevent. The protective device is therefore stiffer in the upper region than in the lower region of the wall element and the damping elements. This can be achieved by arranging at least one stiffening profile extending in the direction of travel in the upper region of the uprights above the wall element, wherein stiffening profiles preferably comprise two box sections arranged one above the other and fastened to one another and to the stanchions. By such a fastening can be realized by the box profiles, the effect of a double-T-beam and thus an extremely high rigidity and guide for impacting vehicles in the longitudinal direction (direction of travel) are ensured. In a preferred embodiment, the wall element can be fastened directly or indirectly to the lower box profile and / or be held pivotably, so that the pivot point is in the region of the box profile.
Zur Unterstützung der Zurückhaltungs- und Umlenkungswirkung des passiven Fahrzeug-Rockhaltesystems können die Pfosten nach vorne in Richtung des Verkehrswegs geneigt sein.To support the restraining and deflecting action of the passive vehicle rock-holding system, the posts may be inclined forward in the direction of the traffic route.
Vorteilhafterweise können in Fahrtrichtung auf der Rückseite der Pfosten eine oder mehrere Abspannungen, vorzugsweise in Form eines Abspanngurtes vorgesehen sein, die eine Verbindung der Pfosten untereinander darstellen und ein Ausbrechen einzelner Pfosten verhindern. In einer bevorzugten Ausführung sind zwei Abspannungen vorgesehen, wobei die eine rückseitig an den Pfosten auf Höhe der Kastenprofile, die andere auf Höhe der oberen Dämpfungselemente verläuft. Die Lehre des Erfindung ist jedoch nicht auf die Verwendung zweier oder mehrerer Abspannungen begrenzt, vielmehr kann für bestimmte Anforderungen an die Schutzeinrichtung nur eine Abspannung ausreichen.Advantageously, in the direction of travel on the back of the post one or more guying, preferably be provided in the form of a guy belt, which represent a compound of the posts with each other and prevent breakage of individual posts. In a preferred embodiment, two braces are provided, the one at the back of the post at the height of the box sections, the other runs at the height of the upper damping elements. However, the teaching of the invention is not limited to the use of two or more guying, but may be sufficient for certain requirements of the protective device only one guy.
Eine bevorzugte Ausgestaltung des Abspanngurtes ist dadurch gekennzeichnet, dass dieser in einem oberen und einem unteren an dem Pfosten anliegenden Bereich befestigt und im Mittelbereich eine Dreiecksform aufweisen kann, wobei das Dach des Dreiecks von dem Pfosten beabstandet ist.A preferred embodiment of the Abspanngurtes is characterized in that this fixed in an upper and a lower voltage applied to the post area and may have a triangular shape in the central region, wherein the roof of the triangle is spaced from the post.
Vorteilhafterweise sind die Pfosten auf einer im Boden verankerten Fußplatte befestigt, so dass ein Ausreißen einzelner Pfosten verhindert und ein einfaches und schnelles Aufstellen der erfindungsgemäßen Schutzeinrichtung auf unterschiedlichen Untergründen beispielsweise auch auf Brücken gewährleistet ist.Advantageously, the posts are mounted on a base plate anchored in the ground, so that tearing of individual posts prevented and a simple and quick installation of the protection device according to the invention on different surfaces, for example, is guaranteed on bridges.
In einer ebenfalls vorteilhaften Ausführungsform kann sich im Falle eines Anpralls ein oder mehrere Pfosten von der Fußplatte trennen, so dass die Konstruktion wie eine bewegliche Wand in Richtung der Fahrbahn abgewandten Seite zurückweichen kann. Hierdurch kann ein Zurückbiegen der Pfosten mit dem Wandelement und somit die Wirkung einer Rampe vermieden werden. Das Fahrzeug-Rückhaltesystem kann stets als eine Wand erhalten bleiben.In a likewise advantageous embodiment, in the event of an impact, one or more posts may separate from the base plate, so that the construction can retreat like a movable wall facing away from the roadway. This can be a bending back of the post with the wall element and thus the effect of a ramp can be avoided. The vehicle restraint system can always be maintained as a wall.
Andere vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Unteransprüchen gekennzeichnet bzw. werden nachstehend mit der Beschreibung der bevorzugten Ausführungsform der Erfindung anhand der Figuren näher dargestellt.Other advantageous developments of the invention are characterized in the dependent subclaims or are presented in more detail below with the description of the preferred embodiment of the invention with reference to FIGS.

Die Darstellung in den beigefügten Figuren erfolgt beispielhaft schematisch. In den Figuren sind jeweils gleiche Bauteile mit jeweils gleichen Bezugszeichen versehen. Ferner sind nur die für das Verständnis der Erfindung wesentlichen Elemente dargestellt.The illustration in the accompanying figures is exemplary schematically. In the figures, the same components are each provided with the same reference numerals. Furthermore, only the essential elements for understanding the invention are shown.
Das in
Im unteren Bereich 13 weist die Schutzeinrichtung 1 an jedem Pfosten 2 übereinander beabstandet angeordnete Dämpfungselemente 4 auf, die an dem Pfosten 2 befestigt und vorzugsweise als metallene Rohre ausgebildet sind. Die von den Dämpfungselementen 4 durch Verformung umzuwandelnde kinetische Energie ist durch eine Anpassung der Wandstärke und/oder des Materials erzielbar. Den Dämpfungselementen 4 in Richtung des Verkehrswegs vorgelagert weist die Schutzeinrichtung 1 jeweils mittig zu den Dämpfungselementen 4 ausgerichtete Längsprofile 6 auf, die vorzugsweise als C-Profil ausgebildet sind. Die Öffnung des C kann dabei sowohl in Richtung des Pfostens 2 als auch in Richtung des Verkehrswegs erfolgen. Zwischen dem Längsprofil 6 und dem Dämpfungselement 4 sowie zwischen dem Pfosten 2 und dem Dämpfungselement 4 sind Verformungsfüllelemente 7 angeordnet, die vorzugsweise mit Streben (in Querrichtung zu dem Verkehrsweg) eine Krafteinleitung im Falle eines Anpralls auf die Dämpfungselemente 4 übertragen, so dass eine gezielte Verformung in einem vorbestimmten Bereich der Dämpfungselemente 4 ermöglicht ist. Hierzu greifen die Streben der Verformungsfüllelemente 7 im wesentlich im mittleren Bereich der oberen bzw. unteren Hälfte des jeweiligen Dämpfungselements 4 in horizontaler Richtung an dem Dämpfungselement 4 an. Die Anordnung der Streben der Verformungsfüllelemente 7 ist nicht auf die dargestellte Art und Weise beschränkt, sie können beispielsweise auch in einem vorbestimmten Winkel in Richtung der meist von schräg vorne anprallenden Fahrzeuge ausgerichtet sein. Auch ist es für die Erfindung nicht unbedingt notwendig, auf beiden Seiten des Dämpfungselements 4 Verformungsfüllelemente 7 anzubringen, es kann auch ausreichen diese zwischen Wandelement 3 und Dämpfungselement 4 oder zwischen Dämpfungselement 4 und Pfosten 2 vorzusehen.In the
Über eine Rahmenkonstruktion 8 sind das obere und untere Dämpfungselement 4 sowie die jeweils zugehörigen Verformungsfüllelemente 7 als eine Baueinheit ausgebildet, die vorgefertigt werden kann und erst an der Baustelle als ein komplettes Bauteil an dem Pfosten 2 befestigbar ist. Auf diese Weise ist eine Verkürzung der Montage sowie eine Kostenersparnis zu erzielen.About a frame structure 8, the upper and lower damping
Dem Verkehrsweg nächstgelegen weist die Schutzeinrichtung 1 im unteren Bereich 13 ein Wandelement 3 auf, das an dem unteren der Kastenprofile 9 sowie im Vorderbereich an den Längsprofilen 6 befestigt, vorzugsweise verschraubt ist. Es wäre auch möglich, das Wandelement 3 anstatt an dem Kastenprofil 9, bzw. zusätzlich, an dem Pfosten 2 zu befestigen. Die Kastenprofile 9 und das Wandelement 3 bilden auf der Seite des Verkehrswegs eine Wandfläche 5, die im steifen oberen Bereich 12 eine Führung entlang des Vertcehrsweges und im relativ zu dem oberen Bereich 12 weicheren unteren Bereich 13 insbesondere eine Dämpfung aber auch eine gewisse Führung für anprallende Fahrzeuge. Das Wandelement 3 verläuft von dem Kastenprofil 9 in einer Schräge in Richtung des Bodens bis zu der vorderen Ebene der Längsprofile 6 und ist am unteren Ende frei endend ausgebildet. Durch das offene untere Ende und die oberseitige Befestigung ist das Wandelement 3 frei in Richtung des Pfostens um den Befestigungspunkt (Drehpunkt) am Kastenprofil 9 bzw. einen nicht gezeigten aber möglichen Befestigungspunkt (Drehpunkt) am Pfosten 2 schwenkbar.Next to the traffic route, the protective device 1 in the
Das passive Fahrzeug-Rückhaltesystem 1 ist in ihrer Gesamtheit um den Winkel α gegenüber einer senkrechten Ebene nach vorne in Richtung des Verkehrsweges geneigt, wobei vorzugsweise die Neigung des Pfostens 2 und die Neigung der Wandfläche 5 im oberen Bereich 12 an den Kastenprofilen 9 sowie die Neigung der Wandfläche 5 im unteren Bereich 13 des Wandelements 3 identisch sind. Als mögliche Neigung könnten 1% bis 10%, vorzugsweise 4% bis 6% vorgesehen sein. Es soll jedoch auch Bestandteil der Lehre der Erfindung sein, dass die Neigungen, beispielsweise durch Variation der Abmaße der einzelnen Elemente, im Bereich der Kastenprofile 9 und des Wandelements 3 auch unterschiedlich sein können.The passive vehicle restraint system 1 is inclined in its entirety by the angle α with respect to a vertical plane forward in the direction of the traffic route, preferably the inclination of the
Im rückwärtigen Bereich sind an den Pfosten 2 zwei Abspannungen 10 vorgesehen, die vorzugsweise als Abspanngurte ausgebildet sind, wobei die obere Abspannung 10 vorzugsweise im Bereich der Kastenprofile 9 und die untere Abspannung 10 vorzugsweise auf Höhe des oberen Dämpfungselements 4 angeordnet ist. Die Abspannung 10 ist jeweils an einem an dem Pfosten 2 anliegenden Bereich mit diesem verschraubt und weist im Mittelbereich die Form eines Dreiecks auf, dessen Katheten sich in Richtung der dem Verkehrsweg abgewandten Seite erstrecken, so dass das Dach des der Dreiecksbereichs von dem Pfosten 2 beabstandet ist. Die Anzahl der Abspannungen 10 ist variabel und an die jeweilige Anforderung an das Fahrzeug-Rückhaltesystem anpassbar, so dass beispielsweise auch eine einzige Abspannung 10 ausreichen kann.In the rear area two

Es wird ausdrücklich darauf hingewiesen, dass alle verschiedenen Merkmalselemente der einzelnen beschriebenen bzw. gezeigten Ausführungsbeispiele beliebig miteinander kombinierbar sind, soweit dies technisch möglich ist und kein Widerspruch besteht. So ist es zum Beispiel möglich, dass Wandelement 3 direkt an dem Pfosten 2 zu befestigen und im unteren Bereich 13 eine andere Neigung der Wandfläche 5 als im oberen Bereich 12 zu gewährleisten. Ferner können beispielsweise Schraubbefestigungen regelmäßig durch Schweißverbindungen ersetzt werden.It is expressly pointed out that all the different feature elements of the individual embodiments described or shown can be combined with one another as far as is technically possible and there is no contradiction. It is thus possible, for example, to fasten the
