Description

Die Erfindung betrifft ein Fahrzeugrückhaltesystem mit einem Pfosten, mit einer mit dem Pfosten verbundenen Platte, insbesondere Grundplatte, wobei die Platte mindestens eine vom Pfosten beabstandete Aussparung aufweist, und mit einer an den Pfosten und an die Platte anschließenden sowie Pfosten und Platte stoffschlüssig verbindenden Schweißnaht, insbesondere Kehlnaht, mit einer Schenkellänge entlang der Platte.The invention relates to a vehicle restraint system with a post, with a plate connected to the post, in particular a base plate, the plate having at least one recess spaced from the post, and with a weld seam adjoining the post and the plate and integrally connecting the post and plate, especially fillet weld, with a leg length along the plate.

Um bei Fahrzeugrückhaltesystemen ein scharnierartiges Wegkippen eines Pfostens an einer Grundplatte zu ermöglichen, ist es aus dem Stand der Technik bekannt ( EP1650351 A2 ), die Grundplatte, an welche der Pfosten angeschweißt und über die dieser auch an einen festen Untergrund befestigt ist, partiell mit einem Stahlband zu verstärken. Das Stahlband befindet sich hierzu auf der Grundplatte und wird über Anker, welche die Grundplatte mit dem festen Untergrund verbinden und hierfür kreisrunde Aussparungen der Grundplatte durchgreifen, an die Grundplatte gezogen. Bei einem entsprechend heftigen Anprall eines Fahrzeugs reißt der Pfosten oberhalb der Schweißnaht ein - wodurch das Fahrzeugrückhaltesystem die Heftigkeit eines Anpralls für das Fahrzeug reduzieren und damit den Schutz der Insassen verbessern soll. Nachteilig bedarf es eines vergleichsweise hohen konstruktiven Aufwands - etwa in der gegenseitigen mechanischen Abstimmung von Grundplatte, Stahlband, Schweißnaht und Pfosten, um das gewünschte Verhalten bzw. die geforderte Anpralleigenschaften des Fahrzeugrückhaltesystems sicherstellen zu können.In order to enable a hinge-like tilting of a post on a base plate in vehicle restraint systems, it is known from the prior art ( EP1650351 A2 ), partially reinforce the base plate to which the post is welded and via which it is also attached to a solid surface with a steel band. For this purpose, the steel strip is located on the base plate and is pulled to the base plate via anchors, which connect the base plate to the solid base and pass through circular recesses in the base plate. In the event of a correspondingly violent impact of a vehicle, the post tears above the weld seam - the purpose of the vehicle restraint system is to reduce the severity of an impact for the vehicle and thus to improve the protection of the occupants. The disadvantage is that a comparatively high amount of construction is required - for example in the mutual mechanical coordination of the base plate, steel strip, weld seam and post, in order to be able to ensure the desired behavior or the required impact properties of the vehicle restraint system.

Dieser Aufwand hinsichtlich der mechanischen Abstimmung kann verringert werden, wenn ein Abschälen des Pfostens von der Grundplatte zugelassen wird - wie dies beispielsweise die DE6608370U offenbart. Laut dieser wird die durchgezogene Schweißverbindung zwischen Pfosten und Grundplatte auf einer Seite des Pfostens abgesetzt. Nachteilig führt ein Abschälen des Pfostens von der Grundplatte allerdings zu lose an einer Leitplanke pendelnden Elementen, welche etwa aufgrund der so erhöhten Verletzungsgefahr als problematisch einzustufen sind.This effort in terms of mechanical adjustment can be reduced if peeling of the post from the base plate is permitted - as is the case, for example DE6608370U disclosed. According to this, the solid welded connection between the post and the base plate is placed on one side of the post. However, peeling off the post from the base plate is disadvantageous elements swinging too loosely on a guardrail, which can be classified as problematic due to the increased risk of injury.

Des Weiteren ist ein Pfosten für ein Fahrzeugrückhaltesystem aus der DE3809896A1 bekannt.Furthermore, a post for a vehicle restraint system is from the DE3809896A1 known.

Die Erfindung hat sich daher die Aufgabe gestellt, ein Fahrzeugrückhaltesystem der eingangs geschilderten Art derart zu verändern, dass unter Gewährleistung einer geringen Verletzungsgefahr eine geforderte Anprallheftigkeit exakt eingehalten werden kann.The object of the invention is therefore to change a vehicle restraint system of the type described at the outset in such a way that a required severity of impact can be met exactly while ensuring a low risk of injury.

Die Erfindung löst die gestellte Aufgabe durch die Merkmale des Anspruchs 1.The invention solves this problem by the features of claim 1.

Indem die Aussparung der Platte an die Schweißnaht mindestens bis zu einem maximalen Abstand von einer Schenkellänge heranreicht, kann die Anprallheftigkeit des Fahrzeugrückhaltesystems im Bereich des Pfostens durch mechanische Schwächung der Grundplatte auf konstruktiv einfache Weise eingestellt werden. Dies unter der Prämisse, nicht auch die Eigenschaften der außenliegenden Schweißnaht zu beeinträchtigen, was erreichbar ist, indem die Aussparung dabei höchstens an der Schweißnaht anschließt - und damit diese nicht schwächt. Eine derartige Aussparung kann zudem vergleichsweise einfach in eine Grundplatte eingebracht werden, wodurch reproduzierbar die Anprallheftigkeit des Fahrzeugrückhaltesystems über die Kriterien der Aussparung eingestellt werden kann. Zudem kann durch diese erfindungsgemäße Schwächung der Grundplatte in bestimmten Bereichen eine scharnierartige Bewegung des Pfostens an der Grundplatte ermöglicht werden, wodurch ein Abschälen des Pfostens und damit ein Lösen des Pfostens von der Platte vermeidbar ist. Mit einem losen Pfostenende im Falle eines Anpralls muss daher nicht gerechnet werden - womit unter anderem Gefährdungspotenzial und Verletzungsgefahr aufgrund derartiger Teile des Fahrzeugrückhaltesystems vermeidbar sind.
Weiter kann es sich aus vorteilhaft herausstellen, dass durch das Einreißen der Platte auch die in den Untergrund eingeleiteten Kräfte reproduzierbar verringert werden können, wodurch eine Verankerung des Fahrzeugrückhaltesystems bei festen Untergründen, beispielsweise an einer Asphalt-, Betonfahrbahn, etc., erst möglich werden kann.Since the recess in the plate reaches the weld seam at least up to a maximum distance of one leg length, the impact force of the vehicle restraint system in the area of the post can be adjusted in a structurally simple manner by mechanically weakening the base plate. This is based on the premise that the properties of the external weld seam should not be impaired, which can be achieved by at most connecting the recess to the weld seam - and thus not weakening it. Such a recess can also be made comparatively easily in a base plate, as a result of which the impact severity of the vehicle restraint system can be set reproducibly using the criteria of the recess. In addition, this weakening of the base plate according to the invention enables a hinge-like movement of the post on the base plate in certain areas, as a result of which a peeling of the post and thus a detachment of the post from the plate can be avoided. A loose end of the post in the event of an impact is therefore not to be expected - which, among other things, can prevent danger and injury from such parts of the vehicle restraint system.
Furthermore, it can be found to be advantageous that the tearing of the plate also reproducibly reduces the forces introduced into the subsurface can be, whereby anchoring of the vehicle restraint system on solid surfaces, for example on an asphalt, concrete roadway, etc., is only possible.

Im Allgemeinen wird erwähnt, dass die Platte des Pfostens eine Grundplatte sein kann, über welche der Pfosten am Untergrund befestigbar ist. Die Platte ist aber auch als Fußplatte denkbar, welche den Pfosten über eine weitere Platte, vorzugsweise Grundplatte, am Untergrund befestigt.In general, it is mentioned that the plate of the post can be a base plate, via which the post can be fastened to the base. However, the plate is also conceivable as a base plate, which attaches the post to the base via a further plate, preferably a base plate.

Die Konstruktion der Grundplatte kann vereinfacht werden, wenn die Aussparung schlitz-, dreieck- oder sichelförmig ausgestaltet ist. Des Weiteren kann eine derartige Form der Ausnehmung die Zuverlässigkeit des Fahrzeugrückhaltesystems verbessern - nämlich durch eine scharnierartige Bewegung des Pfostens.The construction of the base plate can be simplified if the recess is slit, triangular or crescent-shaped. Furthermore, such a shape of the recess can improve the reliability of the vehicle restraint system - namely by a hinge-like movement of the post.

Wird die Aussparung von zwei aneinander anschließenden, geraden Schlitzen ausgebildet, kann dies die Herstellung und damit auch die Kosten der Platte erheblich vereinfachen - beispielsweise, indem die Aussparung durch ein Laserschnittverfahren eingebracht wird. Die genannten Vorteile sind besonders ausgeprägt, wenn die beiden gerade verlaufenden Schlitze im rechten Winkel zueinander stehen und an einem ihrer Enden ineinander übergehen.If the recess is formed by two adjoining, straight slits, this can considerably simplify the manufacture and thus also the cost of the plate - for example by introducing the recess by means of a laser cutting process. The advantages mentioned are particularly pronounced if the two straight slots are at right angles to one another and merge into one another at one of their ends.

Wird der Verlauf der, der Schweißnaht abgewandten Außenkontur der Aussparung aus Konturabschnitten gebildet, die jeweils parallel zur Schweißnaht an einer Pfostenseite des Pfostens verlaufen, kann die scharnierartige Bewegung des Pfostens zur Platte auf konstruktiv einfache Weise vorbestimmt werden. Die im Falle eines Anpralls auf den Pfosten wirkenden Kräfte führen dadurch auch zu einer Rissbildung in der Platte, welche den Pfostenseiten des Pfostens folgt - was die scharnierartige Bewegung des Pfostens festlegt und welche damit reproduzierbar am Fahrzeugrückhaltesystem eintritt. Das erfindungsgemäße Fahrzeugrückhaltesystem kann daher in besonders sicherer Weise ausgebildet werden.If the course of the outer contour of the recess facing away from the weld seam is formed from contour sections which each run parallel to the weld seam on a post side of the post, the hinge-like movement of the post to the plate can be predetermined in a structurally simple manner. The forces acting on the post in the event of an impact also lead to crack formation in the plate, which follows the post sides of the post - which determines the hinge-like movement of the post and which thus reproducibly occurs on the vehicle restraint system. The vehicle restraint system according to the invention can therefore be designed in a particularly safe manner.

Eine bevorzugte Richtung in der scharnierartigen Bewegung des Pfostens kann beispielsweise festgelegt werden, indem die Aussparung bei einem Pfosteneck des Pfostens vorgesehen ist.A preferred direction in the hinge-like movement of the post can be determined, for example, by providing the cutout in a post corner of the post.

Der scharnierartigen Bewegung des Pfostens kann eine bevorzugte Richtung in Fahrtrichtung gegeben werden, wenn die Aussparung bei der, in Fahrtrichtung gesehen ersten Pfostenecke des Pfostens vorgesehen ist, welche Pfostenecke der Richtungsfahrbahn zugewandt ist.The hinge-like movement of the post can be given a preferred direction in the direction of travel if the recess is provided in the first post corner of the post seen in the direction of travel, which post corner faces the directional roadway.

Weist die Platte zwei Aussparungen auf, die an diagonal gegenüberliegenden Pfostenecken des Pfostens vorgesehen sind, kann das Fahrzeugrückhaltesystem auch zwischen zwei Richtungsfahrbahnen mit entgegengesetzten Fahrtrichtungen vorgesehen werden - und dennoch die erfindungsgemäß vorstehend beschriebene Funktion für jede der Richtungsfahrbahnen bieten. Vorzugsweise kann sich das erfindungsgemäße Fahrzeugrückhaltesystem daher auf festem Untergrund, beispielsweise einer Brücke, Fahrbahn, Richtungsfahrbahn, Asphaltfahrbahn, Betonfahrbahn etc. eignen.If the plate has two recesses, which are provided on diagonally opposite post corners of the post, the vehicle restraint system can also be provided between two directional lanes with opposite directions of travel - and yet offer the function described above for each of the directional lanes. The vehicle restraint system according to the invention can therefore preferably be suitable on solid ground, for example a bridge, roadway, directional roadway, asphalt roadway, concrete roadway, etc.

Die Handhabbarkeit des Pfostens bei der Montage kann erleichtert werden, wenn der Pfosten mittig der Platte angeordnet ist. Zudem kann durch diese mittige Anordnung das Verhalten des Pfostens gegenüber der Platte winkelunabhängiger in Bezug auf die Anprallrichtung ausgebildet werden. Derart können beispielsweise die Einsatzmöglichkeiten des erfindungsgemäßen Fahrzeugrückhaltesystems erhöht werden.The handling of the post during assembly can be made easier if the post is arranged in the center of the plate. In addition, with this central arrangement, the behavior of the post with respect to the plate can be made more angle-independent with respect to the direction of impact. In this way, for example, the possible uses of the vehicle restraint system according to the invention can be increased.

Ist die Platte rechteckig ausgebildet und weist diese in ihren Plattenecken Befestigungslöcher zur mechanischen Verbindung mit einem Untergrund auf, können sich die Montage des Pfostens erleichtern und die Handhabbarkeit des Fahrzeugrückhaltesystems verbessern.If the plate is rectangular and it has fastening holes in its plate corners for mechanical connection to a substrate, the assembly of the post can be simplified and the manageability of the vehicle restraint system can be improved.

Die Herstellung des Fahrzeugrückhaltesystems kann sich erleichtern, wenn der Pfosten an der Platte aufgesetzt ist. Zudem kann dies - im Gegensatz zu einem in einer Ausnehmung der Platte eingesetzten Pfosten - eine tiefergehende Schweißverbindung im T-Stoß zulassen, was zu einer mechanisch besonders belastbaren Schweißverbindung führen kann.Manufacturing the vehicle restraint system can be easier if the post is attached to the panel. In addition, in contrast to a post inserted in a recess in the plate, this can permit a deeper weld connection in the T-joint, which can lead to a mechanically particularly robust weld connection.

Die stoffschlüssige Verbindung zwischen Pfosten und Platte kann mechanisch besonders belastbar ausgebildet werden, wenn der Pfosten mit einer umlaufenden Schweißnaht mit der Platte verbunden ist. Zudem kann dem Pfosten durch solch eine umlaufende Schweißnaht im Falle eines Anpralls stets eine scharnierartige Bewegung aufgezwungen werden - und zwar unabhängig vom Anprallwinkel des Fahrzeugs auf das Fahrzeugrückhaltesystem.The integral connection between the post and the plate can be made particularly mechanically strong if the post is connected to the plate with a circumferential weld seam. In addition, a hinge-like movement can always be forced on the post by such a circumferential weld seam in the event of an impact - regardless of the angle of impact of the vehicle with the vehicle restraint system.

Die Konstruktion und damit der Herstellungsaufwand des Fahrzeugrückhaltesystems können weiter vereinfacht werden, wenn der Pfosten ein offenes Hohlprofil aufweist.The construction and thus the manufacturing costs of the vehicle restraint system can be further simplified if the post has an open hollow profile.

Besonders vorteilhaft hinsichtlich der Reduktion der Anprallheftigkeit des Fahrzeugrückhaltesystems kann sich erweisen, wenn das offene Hohlprofil von einem U-Profil, C-Profil oder Sigma-Profil ausgebildet wird.It can prove particularly advantageous with regard to the reduction in the impact severity of the vehicle restraint system if the open hollow profile is formed by a U-profile, C-profile or Sigma profile.

Vorteilhaft kann das Fahrzeugrückhaltesystem eine mechanische Verbindung zwischen der Platte und dem festen Untergrund aufweisen. Zudem kann eine Überbelastung des Befestigungsgrunds des Fahrzeugrückhaltesystems verhindert werden, wenn die erste mechanische Verbindung und die stoffschlüssige Verbindung der Schweißnaht mechanisch belastbarer (zum Beispiel in der Bruchfestigkeit, Zugfestigkeit, Torsionssteifigkeit etc.) als die Platte sind. Dadurch kann sich das erfindungsgemäße Fahrzeugrückhaltesystem für einen festen Untergrund beispielsweise an Brücken, Asphaltfahrbahn etc. besonders eignen, um deren Beschädigungen aufgrund der, vom Fahrzeugrückhaltesystem in diesen eingeleiteten Kräfte zu vermeiden.The vehicle restraint system can advantageously have a mechanical connection between the plate and the solid surface. In addition, an overloading of the fastening base of the vehicle restraint system can be prevented if the first mechanical connection and the integral connection of the weld seam are mechanically stronger (for example in terms of breaking strength, tensile strength, torsional rigidity, etc.) than the plate. As a result, the vehicle restraint system according to the invention can be particularly suitable for a solid subsurface, for example on bridges, asphalt roadways, etc., in order to avoid their damage due to the forces introduced into them by the vehicle restraint system.

Der Pfosten 4 ist in weiterer Folge mit einer Platte 5 über eine außenliegende Schweißnaht 6 stoffschlüssig verbunden, welche Platte 5 als Grundplatte dient und das Fahrzeugrückhaltesystem 1 an einem vorzugsweise festen Untergrund 7 über eine mechanische Verbindung 8 befestigt.According to Fig. 1 For example, a vehicle restraint system 1 is shown with a crash barrier 2.1, 2.2, which is only indicated, and which is connected to a post 4 via a spacer element 3.1, 3.2, which is also only indicated. The post 4 is subsequently cohesively connected to a plate 5 via an external weld 6, which plate 5 serves as a base plate and fastens the vehicle restraint system 1 to a preferably solid base 7 via a mechanical connection 8.

Hierzu durchgreift ein Verbindungselement, nämlich die Schraube 8.2 mit einem Sechskantkopf, je ein kreisrundes Befestigungsloch 9, welches Befestigungsloch 9 von einer vom Pfosten 4 beabstandeten Aussparung 10.1 in der Platte 5 gebildet wird.This mechanical connection 8 releasably fastens the plate 5 to the base 7, as shown, for example - via anchored ground anchors 8.1 and screws 8.2 interacting therewith. For this purpose, a connecting element, namely the screw 8.2 with a hexagon head, passes through a circular fastening hole 9, which fastening hole 9 is formed by a recess 10.1 in the plate 5 spaced from the post 4.

Die Schweißnaht 6 ist als gleichschenkelige Kehlnaht mit der Schenkellänge z bzw. einer Schenkellänge z1 entlang der Platte 5 ausgeführt - was etwa der Fig. 3 entnommen werden kann. Es ist aber auch denkbar, die Schweißnaht 6 als Doppelkehlnaht, HV-Naht mit Kehlnaht oder HY-Naht mit Kehlnaht etc. auszuführen, was nicht dargestellt ist.The weld seam 6 is designed as an isosceles fillet weld with the leg length z or a leg length z1 along the plate 5 - which is about Fig. 3 can be removed. However, it is also conceivable to carry out the weld 6 as a double fillet, HV seam with fillet or HY seam with fillet seam, etc., which is not shown.

Erfindungsgemäß weist die Platte 5 zusätzliche Aussparungen 10.2, 10.3, 10.4 auf. Diese besonderen Aussparungen 10.2, 10.3, 10.4 reichen an der Schweißnaht 6 mindestens bis zu einem maximalen Abstand von einer Schenkellänge z, z1 heran, schließen dabei jedoch höchstens an der Schweißnaht an - wie dies in den Figuren 2 bis 4 erkennbar ist.According to the invention, the plate 5 has additional cutouts 10.2, 10.3, 10.4. These special cutouts 10.2, 10.3, 10.4 extend at the weld 6 at least up to a maximum distance of a leg length z, z1, but at most connect to the weld seam - as shown in the Figures 2 to 4 is recognizable.

So zeigt die Fig. 3, dass die sichelförmige Aussparung 10.2 bis an die Schweißnaht 6 heranreicht und damit an diese anschließt, wohingegen die dreieckförmige Aussparung 10.3 gemäß der Fig. 4 vor der Schweißnaht 6 mit einem Abstand von einer Schenkellänge z, z1 endet bzw. damit an die Schweißnaht 6 genau mit einem maximalen Abstand von einer Schenkellänge z, z1 heranreicht. Fig. 3 und Fig. 4 zeigen daher die beiden Extremstellen. Die Aussparung kann aber auch im Bereich zwischen den beiden Extremstellen an die Schweißnaht heranreichen, was nicht näher dargestellt worden ist.So it shows Fig. 3 that the crescent-shaped recess 10.2 reaches up to the weld 6 and thus adjoins it, whereas the triangular recess 10.3 according to the Fig. 4 ends in front of the weld seam 6 with a distance of a leg length z, z1 or thus exactly reaches the weld seam 6 with a maximum distance from a leg length z, z1. 3 and 4 therefore show the two extreme points. However, the cutout can also reach the weld seam in the area between the two extreme points, which has not been shown in more detail.

Mit solch einer erfindungsgemäßen Ausführung der Aussparungen 10.2, 10.3 kann bei einem Anprall auf das Fahrzeugrückhaltesystem 1 sichergestellt werden, dass sich eine Rissbildung 11 in der Platte 5 entlang der Schweißnaht 6 ergibt, welche von der Aussparung 10.2 mit einer Anprallrichtung 12 ausgeht und an den Rissenden eine Achse 13 festlegt, um die sich der Pfosten 4 scharnierartig gegenüber der Platte 5 bewegen kann. Ein reproduzierbares Anprallverhalten des Fahrzeugrückhaltesystems 1 kann sich derart ergeben, was dazu beitragen kann, die Sicherheit des Fahrzeugrückhaltesystems 1 - beispielsweise in Bezug auf eine vorbestimmte Anprallheftigkeit - besonders zu erhöhen und die in den festen Untergrund 7 eingeleiteten Kräfte zu reduzieren.With such a design of the cutouts 10.2, 10.3 according to the invention, in the event of an impact on the vehicle restraint system 1, it can be ensured that there is a crack formation 11 in the plate 5 along the weld seam 6, which starts from the cutout 10.2 with an impact direction 12 and at the crack ends defines an axis 13 about which the post 4 can move in a hinge-like manner with respect to the plate 5. A reproducible impact behavior of the vehicle restraint system 1 can result in such a way, which can help to particularly increase the safety of the vehicle restraint system 1 - for example in relation to a predetermined impact severity - and to reduce the forces introduced into the solid base 7.

Wie des Weiteren den Figuren 2 bis 4 im Detail zu entnehmen, sind diverse Formen der Aussparung 10.2, 10.3, 10.4 vorstellbar. Neben den dargestellten sichel- oder dreieckförmigen Aussparungen 10.2, 10.3 ist auch eine schlitzförmige Aussparungen 10.4 vorstellbar. Eine Ausführungsvarianten für Letztere ist in der Figur 2 rechts dargestellt. Diese Aussparung 10.4 wird durch zwei aneinander anschließende, gerade Schlitze 14.1, 14.2 ausgebildet, welche an jeweils einen ihrer Enden ineinander übergehen und im rechten Winkel zueinander stehen. Diese können zudem vergleichsweise einfach durch ein Laserschneidverfahren in eine Platte 5 eingebracht werden.Like the further Figures 2 to 4 Various forms of recess 10.2, 10.3, 10.4 can be imagined in detail. In addition to the crescent-shaped or triangular cutouts 10.2, 10.3 shown, a slot-shaped cutouts 10.4 is also conceivable. A variant for the latter is in the Figure 2 shown on the right. This recess 10.4 is formed by two adjoining straight slots 14.1, 14.2, which merge into one another at one of their ends and are at right angles to one another. These can also can be introduced into a plate 5 comparatively easily by means of a laser cutting method.

Der Fig. 2 ist auch zu entnehmen, dass die Außenkontur 15 der Aussparungen 10.3 sowie auch der Aussparung 10.4 jeweils aus zwei Konturabschnitten 15.1, 15.2 bzw. 15.2, 15.3 gebildet wird. Diese Konturabschnitte 15.1, 15.2, 15.3 verlaufen parallel zur Schweißnaht 6 an je einer Pfostenseite 4.5, 4.6, 4.7 des Pfostens 4 und folgen damit dem Verlauf 17 der Schweißnaht 6 in diesem Bereich. Damit kann sichergestellt werden, dass die Platte 5 bei einem Anprall entlang der Pfostenseiten 4.5 und 4.6 bzw. 4.6 und 4.7 aufreißt - womit sich die scharnierartige Bewegung des Pfostens 4 ergibt.Of the Fig. 2 it can also be seen that the outer contour 15 of the cutouts 10.3 and also of the cutout 10.4 are each formed from two contour sections 15.1, 15.2 and 15.2, 15.3. These contour sections 15.1, 15.2, 15.3 run parallel to the weld 6 on each post side 4.5, 4.6, 4.7 of the post 4 and thus follow the course 17 of the weld 6 in this area. This can ensure that the plate 5 tears open in the event of an impact along the side of the post 4.5 and 4.6 or 4.6 and 4.7 - which results in the hinge-like movement of the post 4.

Im Allgemeinen wird erwähnt, dass beispielsweise die jeweiligen Konturabschnitte 15.1, 15.2 bzw. 15.2, 15.3 der Aussparungen 10.3, 10.4 im rechten Winkel aufeinander stehen können, wie dies an der dreieckförmige Aussparung 10.3 und an der schlitzförmige Aussparungen 10.4 nach Fig. 2 zu erkennen ist. Im Allgemeinen wird weiter erwähnt, dass die dreieckförmige Aussparung 10.3 in der Kontur einem rechtwinkeligen Dreieck folgen kann.In general, it is mentioned that, for example, the respective contour sections 15.1, 15.2 or 15.2, 15.3 of the cutouts 10.3, 10.4 can be at right angles to one another, as is the case with the triangular cutout 10.3 and the slit-shaped cutouts 10.4 Fig. 2 can be seen. In general, it is further mentioned that the triangular cutout 10.3 can follow a right-angled triangle in the contour.

Zudem ist in den Figuren 1 und 2 gezeigt, dass sich die Aussparungen 10.2, 10.3, 10.4 jeweils bei den Pfostenecken 4.1, 4.2, 4.3 der abgerundeten Pfostenecken 4.1, 4.2, 4.3, 4.4 des Pfostens 4 befinden - insbesondere sich auf diese Bereiche der Pfostenecken 4.1, 4.2, 4.3 des Pfostens 4 beschränken.In addition, in the Figures 1 and 2nd shown that the recesses 10.2, 10.3, 10.4 are each at the post corners 4.1, 4.2, 4.3 of the rounded post corners 4.1, 4.2, 4.3, 4.4 of the post 4 - in particular on these areas of the post corners 4.1, 4.2, 4.3 of the post 4 restrict.

Die Aussparungen 10.2 und 10.3 sind jeweils auf der, in Fahrtrichtung 16.1 bzw. 16.2 gesehen ersten Pfostenecke 4.1 bzw. 4.2 des Pfostens 4 vorgesehen, welche Pfostenecke 4.1 bzw. 4.2 der Richtungsfahrbahn 70.1 bzw. 70.2 zugewandt ist - auf diese Weise ist die Rissbildung 11 und damit die scharnierartige Bewegung des Pfostens 4 begünstigt.The recesses 10.2 and 10.3 are each provided on the first post corner 4.1 or 4.2 of the post 4, as seen in the direction of travel 16.1 or 16.2, which post corner 4.1 or 4.2 faces the directional roadway 70.1 or 70.2 - in this way the crack formation is 11 and thus favors the hinge-like movement of the post 4.

Da die beiden Aussparungen 10.2, 10.3 an diagonal gegenüberliegenden Pfostenecken 4.1, 4.2 des Pfostens 4 vorgesehen sind, ist es möglich, das Fahrzeugrückhaltesystem 1 für Verkehrswege mit zwei Richtungsfahrbahnen 70.1 bzw. 70.2 mit entgegengesetzten Fahrtrichtungen 16.1 bzw. 16.2 zu verwendet - womit eine vielseitige Einsatzmöglichkeit des Fahrzeugrückhaltesystems 1 gewährleistet werden kann.Since the two cutouts 10.2, 10.3 are provided on diagonally opposite post corners 4.1, 4.2 of the post 4, it is possible to use the vehicle restraint system 1 for traffic routes with two directional lanes 70.1 or 70.2 with opposite directions of travel 16.1 or 16.2 - which makes them versatile in use of the vehicle restraint system 1 can be guaranteed.

Der Pfosten 4 ist mittig der rechteckig ausgebildeten Platte 5 angeordnet, was ein Verhalten des Pfostens 4 im Wesentlichen unabhängig von der Anprallrichtung 12 sicherstellt. Des Weiteren weist die Platte 5 in ihren Plattenecken je ein Befestigungsloch 9 für ein Verbindungselement der mechanischen Verbindung 8 auf.The post 4 is arranged in the center of the rectangular plate 5, which ensures that the post 4 behaves essentially independently of the direction of impact 12. Furthermore, the plate 5 has in each of its plate corners a fastening hole 9 for a connecting element of the mechanical connection 8.

Der Pfosten 4 ist außerdem auf der Platte 5 aufgesetzt, was eine standfeste stoffschlüssige Verbindung bzw. Kehlnaht garantiert. Dies besonders in jenem Fall, in welchem der Pfosten 4 mit einer umlaufenden Schweißnaht 6 mit der Platte 5 verbunden ist.The post 4 is also placed on the plate 5, which guarantees a stable material connection or fillet weld. This is particularly the case in which the post 4 is connected to the plate 5 by a circumferential weld 6.

Der Pfosten 4 nach Fig. 1 und 2 weist ein geschlossenes Hohlprofil 18 auf, wobei jedoch - wenn auch nicht dargestellt - auch offene Hohlprofile, etwa ein U-Profil, C-Profil oder Sigma-Profil vorstellbar sind.Post 4 after Fig. 1 and 2nd has a closed hollow profile 18, but - although not shown - open hollow profiles, such as a U-profile, C-profile or Sigma profile, are also conceivable.

Um das scharnierartige Verhalten des Pfostens 4 zu verbessern, sind die erste mechanische Verbindung 8 und die stoffschlüssige Verbindung der Schweißnaht 6 mechanisch belastbarer als die der Platte 5. Durch die vorzugsweise geringere Bruchfestigkeit der Platte 5 gegenüber den an diese Platte 5 angebundenen Verbindungen kann sichergestellt werden, dass die Platte 5 im Falle eines Anpralls entsprechend der Vorgaben der Ausnehmungen 10.2, 10.1 parallel zu den Pfostenseiten 4.1, 4.2, 4.3, 4.4 bzw. der Schweißnaht 6 einreißt.In order to improve the hinge-like behavior of the post 4, the first mechanical connection 8 and the integral connection of the weld seam 6 are mechanically stronger than that of the plate 5. The preferably lower breaking strength of the plate 5 compared to the connections connected to this plate 5 can be ensured that, in the event of an impact, the plate 5 tears parallel to the post sides 4.1, 4.2, 4.3, 4.4 or the weld 6 in accordance with the specifications of the recesses 10.2, 10.1.
