Description

Die Erfindung betrifft ein Fahrzeugrückhaltesystem mit mindestens einem Pfosten, mit wenigstens einer Schutzplanke, dessen Plankenprofil einen mittleren Plankensteg und an den Plankensteg oberhalb und unterhalb anschließende Plankenschenkel aufweist, und mit mindestens einem, zwischen Pfosten und Schutzplanke vorgesehenen Distanzhalter, der einen mit dem Pfosten fest verbundenen, ersten Halteschenkel und einen mit der Schutzplanke fest verbundenen zweiten Halteschenkel aufweist.The invention relates to a vehicle restraint system having at least one post, with at least one guard rail, the plank profile has a central plank web and the plank web above and below plank legs, and with at least one, provided between the post and guard rail spacers, the one firmly connected to the post , First holding leg and having a fixedly connected to the protective barrier second holding leg.

Um bei einem Fahrzeugrückhaltesystem eine Schutzplanke an einem Pfosten zu befestigen, sind aus dem Stand der Technik mehrteilige Distanzhalter bekannt ( DE2202510A , EP1564334B1 , AT004689U1 , EP1 061179B1 ).In order to attach a protective barrier to a post in a vehicle restraint system, multi-part spacers are known from the prior art ( DE2202510A . EP1564334B1 . AT004689U1 . EP1 061179B1 ).

Beispielsweise werden in der DE2202510A zwei parallel zur Schutzplanke verlaufende Distanzhalterprofile gezeigt, die je einen mit dem Pfosten fest verbundenen, ersten Halteschenkel und einen mit der Schutzplanke fest verbundenen, zweiten Halteschenkel aufweisen. Solch ein aus mehreren Profilen ausgebildeter Distanzhalter ist konstruktiv aufwendig unter vergleichsweise hohen Kosten herzustellen. Zudem bedarf solch ein mehrteiliger Distanzhalter eines hohen Montageaufwands beim Zusammenbau, zumal durch seine Profilform eine exakte Ausrichtung dessen Teile erforderlich ist, um vorgegebene Montageöffnungen frei von Profilüberlappungen zu halten.For example, in the DE2202510A two running parallel to the guardrail spacer profiles shown, each having a fixedly connected to the post, first holding leg and a fixed to the guardrail, second holding leg. Such a trained from several profiles spacers is structurally complex to produce at relatively high cost. In addition, such a multi-part spacer requires a high assembly cost when assembling, especially as a result of its profile shape exact alignment of the parts is required to keep predetermined mounting holes free of profile overlaps.

In Bezug auf diese Nachteile lässt auch der mehrteilige Distanzhalter der EP1061179B1 keine Verbesserungen erkennen, welcher sich aus zwei Haltewinkeln ausbildet, die oberhalb oder unterhalb des Plankenstegs der Schutzplanke vorgesehen sind. Dieser Distanzhalter soll mithilfe einer Verformung seiner Haltewinkel Stoßenergie abbauen, bevor Pfosten und/oder die Schutzplanke weitere Stoßenergie aufnehmen. Bekanntermaßen weisen Pfosten und/oder die Schutzplanke unterschiedliche Steifigkeiten auf. Da nun die Formänderungen der Haltewinkel von den Parametern des Anpralls abhängen, wirken je nach Art eines Anpralls unterschiedliche mechanische Steifigkeiten des Fahrzeugrückhaltesystems auf das rückzuhaltende Fahrzeug. Sollbruchstellen an den Haltewinkeln, um deren Verformungen in bestimmte Bahnen zu lenken, können diese Nachteile nicht ganz beseitigen.With regard to these disadvantages, the multi-part spacer of the EP1061179B1 recognize no improvements, which is formed by two brackets, which are provided above or below the plank ridge of the guardrail. This spacer is intended to break down impact energy by means of a deformation of its holding angle before the posts and / or the guardrail provide further impact energy take up. As is known, posts and / or the guardrail have different rigidity. Since the shape changes of the bracket depend on the parameters of the impact, different mechanical stiffnesses of the vehicle restraint system act on the vehicle to be backed up, depending on the type of impact. Predetermined breaking points on the brackets in order to direct their deformation in certain tracks, can not completely eliminate these disadvantages.

Es ist daher die Aufgabe der Erfindung, ausgehend vom eingangs geschilderten Stand der Technik ein kostengünstiges Fahrzeugrückhaltesystem zu schaffen, das nicht nur einfach und schnell montiert werden kann, sondern auch unabhängig von Parametern des Anpralls eine hohe Leistungsfähigkeit gewährleistet.It is therefore an object of the invention, starting from the above-described prior art to provide a cost-effective vehicle restraint system that can be mounted not only simple and fast, but also ensures high performance regardless of parameters of the impact.

Die Erfindung löst die gestellte Aufgabe dadurch, dass der Distanzhalter als zwei-schenkliger Haltewinkel ausgebildet ist, dessen erster Halteschenkel oberhalb des Plankenstegs mit dem Pfosten und dessen zweiter Halteschenkel unterhalb des Plankenstegs mit der Schutzplanke fest verbunden sind.The invention solves the problem set by the fact that the spacer is designed as a two-legged bracket, the first retaining leg above the plank web with the post and the second holding leg are firmly connected below the plank web with the guardrail.

Ist der Distanzhalter als zweischenkliger Haltewinkel ausgebildet, kann ein einfach herzustellender und damit kostengünstiger Distanzhalter zur Verfügung gestellt werden, der sich zudem durch eine Vereinfachung der Montage auszeichnen kann. Besonders aber kann diese konstruktive Ausführung des Distanzhalters zur Erhöhung der Leistungsfähigkeit des Fahrzeugrückhaltesystems beitragen, wenn dessen erster Halteschenkel oberhalb des Plankenstegs mit dem Pfosten und dessen zweiter Halteschenkel unterhalb des Plankenstegs mit der Schutzplanke fest verbunden sind. Die erhöhte Steifigkeit bzw. Formstabilität des winkelförmigen Distanzhalters in Kombination mit dessen erfindungsgemäßer Einspannung an Pfosten und Schutzplanke kann nämlich stets für eine kontrollierte Wirkung zwischen Pfosten und Schutzplanke sorgen. Dies kann beispielsweise auch für ein gezieltes Lösen bzw. Ausknöpfen der festen Verbindung zwischen Pfosten und Schutzplanke genutzt werden, beispielsweise damit die Zugwirkung der Schutzplanke auf das rückzuhaltende Fahrzeug frei von der Steifigkeit des Pfostens wirken kann, der auch, ohne damit die Funktionalität des Fahrzeugrückhaltesystems zu gefährden, wegknicken kann. Zudem kann dies auch die bei der Verformung des Pfostens wirkenden Torsionskräfte von Verbindungselementen zwischen den Schutzplanken fernhalten. Der Zusammenhalt der Schutzplanken bzw. die Stabilität des Schutzplankenstrangs kann dadurch deutlich erhöht werden, was der Standfestigkeit des Fahrzeugrückhaltesystems förderlich sein kann. Erfindungsgemäß kann trotz des verhältnismäßig steifen Distanzhalters dennoch mit einer geringen Anprallheftigkeit gerechnet werden, die für alle Anprallfälle reproduzierbar eine hohe Leistungsfähigkeit sicherstellen kann, und zwar -im Gegensatz zum Stand der Technik- unabhängig von unterschiedlichen Umständen, Bedingungen etc. eines Anpralls.If the spacer is designed as a two-legged bracket, a simple to manufacture and therefore more cost-effective spacer can be made available, which can also be characterized by a simplification of the assembly. But in particular, this constructive design of the spacer to increase the performance of the vehicle restraint system contribute if its first holding leg above the plank web with the post and the second holding leg are firmly connected below the plank bridge with the guardrail. The increased rigidity or dimensional stability of the angle-shaped spacer in combination with its inventive clamping on posts and guardrail can namely always ensure a controlled effect between the post and guardrail. This can also be used, for example, for a targeted release or Ausknöpfen the solid connection between the post and guardrail, for example, so that the traction of the guardrail can act on the vehicle to be restrained free of the rigidity of the post, which, without so that the functionality of the vehicle restraint system can endanger, can bend away. In addition, this can also keep the forces acting on the deformation of the post torsional forces of fasteners between the guardrails. The cohesion of the crash barrier and the stability of the barrier rail can be significantly increased, which can be beneficial to the stability of the vehicle restraint system. According to the invention, despite the relatively stiff spacer can still be expected with a low impact severity, which can ensure reproducible high performance for all impact cases, and - in contrast to the prior art - regardless of different circumstances, conditions, etc. of an impact.

Die Hebelwirkung des Distanzhalters auf seine Verbindungselemente mit dem Pfosten kann erhöht werden, wenn die beiden Halteschenkel im stumpfen Winkel aneinander anschließen. Dieser Verlauf der verhältnismäßig breiten Spreizung der Halteschenkel kann auch einer einfacheren Montage bzw. Wartung des Fahrzeugrückhaltesystems dienlich sein, da die Zugänglichkeit zu dessen entsprechenden Stellen erleichtert ist.The lever effect of the spacer on its connecting elements with the post can be increased if the two holding legs connect at an obtuse angle to each other. This course of the relatively wide spread of the holding leg can also be a simpler installation and maintenance of the vehicle restraint system useful, since the accessibility is facilitated to its corresponding points.

Nimmt der Distanzhalter in seiner Breite vom dem, mit dem Pfosten verbundenen ersten Halteschenkel zum zweiten Halteschenkel hin zu, können aufgrund einer dadurch verbesserten Zugänglichkeit der Verbindungselemente Montage und Wartung weiter erleichtert werden - wodurch auch entsprechende Montagegeräte etc. einsetzbar sind.If the spacer increases in width from the first holding limb connected to the post to the second holding limb, assembly and maintenance can be further facilitated due to improved accessibility of the connecting elements.

Material- und in weiterer Folge kostensparend kann die Endbreite des ersten Halteschenkels der Breite des Pfostens entsprechen.Material and subsequently cost-saving, the end width of the first retaining leg of the width of the post correspond.

Endet der zweite Halteschenkel in zwei Flanschen, die jeweils mit der Schutzplanke fest verbunden sind, kann die Einspannung der Verbindung zwischen Distanzhalter und Schutzplanke mechanisch fester ausgeführt werden. Die Standfestigkeit des Fahrzeugrückhaltesystems kann damit erhöht werden. Auch kann diese zwei Einspannbereiche aufweisende feste Verbindung zur Reduktion der Kippneigung des Distanzhalters beitragen. Auch kann so eine unterschiedlich feste Verbindung zwischen Distanzhalter und Pfosten bzw. Distanzhalter und Schutzplanke ermöglicht werden. Somit sind im Falle eines Anpralls reproduzierbar hohe Leistungsfähigkeit und Funktionssicherheit des Fahrzeugrückhaltesystems sicherzustellen.Ends the second holding leg in two flanges, which are each firmly connected to the guardrail, the clamping of the connection between the spacer and guardrail can be made mechanically stronger. The stability of the vehicle restraint system can thus be increased. Also, these two clamping areas contribute solid compound to reduce the tilt tendency of the spacer. Also, a different firm connection between spacers and posts or spacers and guardrail can be made possible. Thus, in the case of an impact reproducibly high performance and reliability of the vehicle restraint system to ensure.

Die Montage der Verbindungselemente zwischen Distanzhalter und Schutzplanke kann erleichtert und damit beschleunigt werden, wenn der seitliche Abstand zwischen den Flanschen größer ist als die Breite des Pfostens.The assembly of the connecting elements between spacer and guardrail can be facilitated and thus accelerated if the lateral distance between the flanges is greater than the width of the post.

Liegen die beiden Flansche auf Abstand zum sich zwischen erstem und zweitem Halteschenkel ausbildenden Haltesteg, kann dies der Steifigkeit des Distanzhalters förderlich sein. Aufgrund der dadurch erhöhten Formstabilität des Distanzhalters können vom erfindungsgemäßen Fahrzeugrückhaltesystem also selbst vergleichsweise hohe Stoßenergien sicher und in vorgesehener bzw. reproduzierbarer Weise abgetragen werden.If the two flanges are at a distance from the retaining web forming between the first and second retaining limbs, this can promote the rigidity of the spacer. Due to the thus increased dimensional stability of the spacer can thus be removed safely and in the intended or reproducible manner by the vehicle restraint system according to the invention even comparatively high impact energies.

Die mechanische Kraftkopplung zwischen Schutzplanke und Pfosten kann verbessert werden, wenn sich der zwischen erstem und zweitem Halteschenkel ausbildende Haltesteg auf Höhe des Plankenstegs der Schutzplanke befindet.The mechanical power coupling between the guardrail and posts can be improved if the forming between the first and second holding leg retaining bar is at the level of the plank ridge of the guardrail.

Verläuft der Haltesteg, der sich zwischen erstem und zweitem Halteschenkel ausbildet, am Distanzhalter durchgehend, kann eine vergleichsweise hohe mechanische Steifigkeit am Distanzhalter gegenüber anprallbedingten Verformungskräften ermöglich werden.If the retaining web, which forms between the first and second retaining limbs, extends continuously along the spacer, a comparatively high mechanical rigidity on the spacer can be made possible with respect to impact-induced deformation forces.

Sind Distanzhalter und Pfosten über ein Verbindungselement miteinander fest verbundenen und weist der erste Halteschenkel eine vom Verbindungselement durchgegriffene Montageöffnung auf, die sich in ihrem Öffnungsquerschnitt zumindest abschnittsweise erweitert, kann das Ausknöpfen der Verbindungselemente zwischen Distanzhalter und Pfosten erleichtert werden. Dies kann ein gewünschtes Lösen der festen Verbindung zwischen Schutzplanke und Pfosten sicherstellen, und so eine reproduzierbare Funktionsweise des Fahrzeugrückhaltesystems gewährleisten.Are spacers and posts firmly connected to each other via a connecting element and has the first retaining leg on a durchgegriffene by the connecting member mounting opening, which widens in its opening cross-section at least partially, the Ausknöpfen the fasteners between spacers and posts can be facilitated. This can be a desired Ensure release of the fixed connection between the guard rail and the post, thus ensuring a reproducible functioning of the vehicle restraint system.

Einfache Konstruktionsverhältnisse können sich ergeben, wenn die Montageöffnung schlüssellochförmig ausgebildet ist.Simple construction conditions may arise when the mounting hole is keyhole-shaped.

Der erfindungsgemäße Distanzhalter kann sich insbesondere auszeichnen, wenn dieser im überlappenden Stoßbereich der Schutzplanken vorgesehen und mit diesen Schutzplanken fest verbunden ist. Durch einen sich im Fall eines Anpralls vom Pfosten lösenden Distanzhalter, kann nämlich vermieden werden, dass ein Pfosten auf die Verbindungselemente von Schutzplanken mechanische belastend einwirkt. Der Stoßbereich der Schutzplanken bzw. die diesbezüglichen Verbindungselemente können also vor Überbelastungen geschützt werden, was zu einem mechanisch belastbaren Schutzplankenstrang und damit standfesten Fahrzeugrückhaltesystem führen kann.The spacer according to the invention may be distinguished, in particular, if it is provided in the overlapping joint region of the protective barriers and firmly connected to these protective barriers. By in the case of an impact from the post-releasing spacers, namely, it can be avoided that a post acts on the fasteners of guard rails mechanical stress. The joint area of the guard rails and the related fasteners can therefore be protected from overloads, which can lead to a mechanically robust safety barrier and thus stable vehicle restraint system.

Liegt der obere und/oder der untere Plankenschenkel insbesondere endseitig am Pfosten an, kann durch diese Abstützung die Formstabilität der Schutzplanke gegenüber anprallbedingter Verformung erheblich erhöht werden. Zudem kann dies die Trennfunktion des Distanzhalters vom Pfosten unterstützen und damit die Verbindungselemente zwischen den Leitplanken entlasten, was die Standfestigkeit des Fahrzeugrückhaltesystems erhöhen kann.If the upper and / or the lower plank limb lies against the post, in particular at the end, the dimensional stability of the protective plank with respect to impact-induced deformation can be considerably increased by this support. In addition, this can support the separation function of the spacer from the post and thus relieve the fasteners between the guardrails, which can increase the stability of the vehicle restraint system.

Die Erfindung hat sich außerdem die Aufgabe gestellt, ein Verfahren zu Herstellung eines Distanzhalters für ein Fahrzeugrückhaltesystem zu schaffen, das einfach handzuhaben ist und eine hohe Steifigkeit bzw. Formstabilität aufweist.The invention has also the object of providing a method for producing a spacer for a vehicle restraint system, which is easy to handle and has a high rigidity or dimensional stability.

Die Erfindung löst die gestellte Aufgabe dadurch, dass zur Herstellung eines einteiligen Distanzhalters aus einem Blech in einem Abkantbiegeschritt ein zweischenkliger Haltewinkel mit aneinander in stumpfem Winkel anschließenden Halteschenkeln abgetrennt wird.The invention solves the problem set by the fact that for the production of a one-piece spacer from a sheet in a Abkantbiegeschritt a zweischenkliger Bracket is separated with adjoining each other at an obtuse angle holding legs.

Wird zur Herstellung eines einteiligen Distanzhalters aus einem Blech in einem Abkantbiegeschritt ein zweischenkliger Haltewinkel mit aneinander in stumpfem Winkel anschließenden Halteschenkeln abgetrennt, kann mit einem Einzelhubverfahren schnell und kostengünstig - auf eine mehrteilige Ausführung des Distanzhalters verzichtend - ein Fahrzeugrückhaltesystem geschaffen werden, das höchsten Erfordernissen hinsichtlich Standfestigkeit und Funktion gerecht wird.If, for the production of a one-piece spacer from a metal sheet in a Abkantbiegeschritt a zweischkliger bracket with adjoining each other at an obtuse angle holding legs, can quickly and inexpensively - waiving a multi-part design of the spacer - a vehicle restraint system can be created with a Einzelhubverfahren - the highest requirements in terms of stability and function justice.

Werden die Distanzhalter nacheinander, auf jeweilige Lücke zwischen den Flanschen gereiht vom Blech abgetrennt, kann durch diese verkettete Reihenfolge am Blech ein besonders schnittreduziertes Verfahren ermöglicht werden. Dies kann für eine erhebliche Kostenreduktion in der Herstellung genützt werden.If the spacers are successively separated from the metal sheet on the respective gap between the flanges, a particularly reduced-cutting process can be made possible by this chain-linked sequence on the metal sheet. This can be used for a significant cost reduction in manufacturing.

Das beispielsweise nach Fig. 1 dargestellte Fahrzeugrückhaltesystem 1 zeigt mehrere verankerte Pfosten 2, 3, an denen Schutzplanken 4 und/oder 5 befestigt sind. Von diesen Pfosten 2, 3 trägt der Pfosten 3 die beiden Schutzplanken 4, 5 bzw. deren überlappenden Stoßbereich 6. Über diesen Stoßbereich 6 werden die Schutzplanken 4, 5 zu einem Schutzplankenstrang 7 bzw. Leitplankenband zusammengehalten. Gemäß Fig. 3 sind die wellenförmigen Plankenprofile der Schutzplanken 4, 5 näher zu erkennen. Es ist jedoch jegliche andere Profilform, beispielsweise Profil A (Armco), Profil B (Bethlehem) oder dergleichen, denkbar. Das Plankenprofil der Schutzplanken 4, 5 bildet sich aus einem mittleren Plankensteg 8 und an diesen Plankensteg 8 jeweils oberhalb und unterhalb anschließenden Plankenschenkeln 9, 10. Zwischen den Schutzplanken 4 bzw. 5 und den Pfosten 2, 3 sind einteilige Distanzhalter 11 vorgesehen. Diese Distanzhalter 11 weisen einen mit dem Pfosten 2, 3 fest verbundenen ersten Halteschenkel 12 und einen mit der Schutzplanke 4 bzw. 5 fest verbundenen, zweiten Halteschenkel 13 auf.For example, after Fig. 1 shown vehicle restraint system 1 shows several anchored posts 2, 3, where guard rails 4 and / or 5 are attached. Of these posts 2, 3 carries the post 3, the two guard rails 4, 5 and their overlapping joint area 6. About this joint area 6, the guard rails 4, 5 are held together to form a guard rail 7 and guardrail band. According to Fig. 3 the wave-shaped plank profiles of the guard rails 4, 5 can be seen closer. However, any other profile shape, for example profile A (Armco), profile B (Bethlehem) or the like, is conceivable. The plank profile of the guard rails 4, 5 is formed from a central plank web 8 and to this plank web 8 each above and below subsequent plank legs 9, 10. Between the guard rails 4 and 5 and the posts 2, 3 one-piece spacers 11 are provided. These spacers 11 have a first holding leg 12 fixedly connected to the post 2, 3 and a second holding leg 13 fixedly connected to the guard rail 4 or 5.

Konstruktive Einfachheit am Distanzhalter 11 samt erleichterter Montage- und Wartungsmöglichkeit ergeben sich, indem der Distanzhalter als zweischenkliger Haltewinkel 111 ausgebildet ist. Zudem kann solch ein Distanzhalter 11 aus einem Blech in einem Abkantbiegeschritt hergestellt werden, was hierbei erhebliche Kostenvorteile schafft. Der erste Halteschenkel 12 des Distanzhalters 11 ist oberhalb des Plankenstegs 8 mit dem Pfosten 3, dessen zweiter Halteschenkel 13 unterhalb des Plankenstegs 8 mit der Schutzplanke 4 fest verbunden, sodass unter Berücksichtigung der hohen Steifigkeit des winkelförmigen Distanzhalters 11 mit einem sicheren Lösen der festen Verbindung 14 zwischen Pfosten 3 und Schutzplanken 4, 5 zu rechnen ist. Dies kann sowohl durch Bruch des Verbindungselements 15 bzw. der Schraubverbindung oder auch durch ein Ausknöpfen erreicht werden, indem der Distanzhalter 11 - einer Verformung wiedersetzend - sich in seiner Montagelage gegenüber dem Pfosten 3 verändert. Mithilfe der bei Bedarf sicher lösbaren festen Verbindung 14 kann die Rückhaltewirkung des Systems mithilfe der Schutzplanken 4, 5 bzw. des Schutzplankenstrangs 7 eingeleitet werden. Die Pfosten 2 weisen also einen reduzierten Einfluss auf den Distanzhalter 11 sowie auf die Funktion des Rückhaltesystems 1 im Falle eines Fahrzeuganpralls auf - etwa durch eine Schwächung der Verbindung zwischen Distanzhalter 11 und Schutzplanken 4, 5. Daraus folgend bzw. aufgrund der erfindungsgemäß hohen mechanischen Stabilität und Belastbarkeit des Distanzhalters 11, der die Schutzplanken 4, 5 besonders stark und sicher verbindet, wird also ein Fahrzeugrückhaltesystem 1 zur Verfügung gestellt, das auch weitgehend unabhängig von Anprallwinkel, -geschwindigkeit etc. und trotz vergleichsweise hoher Steifigkeit des Distanzhalters 11 eine verbesserte Leistungsfähigkeit sicherstellt.Constructive simplicity on the spacer 11 together with facilitated installation and maintenance options arise by the spacer is designed as a two-legged bracket 111. In addition, such a spacer 11 can be made of a metal sheet in a Abkantbiegeschritt what this creates significant cost advantages. The first retaining leg 12 of the spacer 11 is fixedly connected above the plank web 8 to the post 3, the second retaining leg 13 below the plank web 8 with the protective barrier 4, so taking into account the high rigidity of the angular spacer 11 with a secure release of the fixed connection 14th between post 3 and crash barriers 4, 5 is expected. This can be achieved both by breaking the connecting element 15 or the screw connection or by a Ausknöpfen by the spacer 11 - a deformation re-changing - changed in its mounting position relative to the post 3. By means of the securely detachable if necessary solid compound 14, the retention effect of the system using the guard rails 4, 5 and the guard rail 7 can be initiated. The posts 2 thus have a reduced influence on the spacer 11 and on the function of the restraint system 1 in the event of a vehicle collision - such as a weakening of the connection between spacers 11 and crash barriers 4, 5. Consequently, or due to the high mechanical stability according to the invention and load capacity of the spacer 11, which connects the guard rails 4, 5 particularly strong and secure, so a vehicle restraint system 1 is provided which also largely independent of impact angle, speed, etc. and despite comparatively high rigidity of the spacer 11 ensures improved performance ,

Die beiden Halteschenkel 12, 13 schließen in stumpfem Winkel 16 aneinander an, was die Krafteinleitung zum Lösen der festen Verbindung 14 erleichtert. Zudem bilden der so nach außen geneigte Halteschenkel 13 eine Auflagefläche für die jeweilige Schutzplanke 4, 5 aus, was die Montage des Fahrzeugrückhaltesystems 1 erleichtert.The two holding legs 12, 13 close at an obtuse angle 16 to each other, which facilitates the introduction of force to release the fixed connection 14. In addition, the retaining leg 13, which is inclined outwards, form a support surface for the respective safety barrier 4, 5, which facilitates the installation of the vehicle restraint system 1.

Gemäß Fig. 1 und 2 kann erkannt werden, dass der Distanzhalter 11 in seiner Breite 17 vom mit dem Pfosten 3 verbundenen ersten Halteschenkel 12 zum zweiten Halteschenkel 13 hin zunimmt. Der Distanzhalter 11 ist damit trapezförmig ausgebildet, wobei seine Endbreite 18 am ersten Halteschenkel 12 der Breite des Pfostens 3 entspricht. Der Distanzhalter 11 ist damit äußerst Material sparend und damit kostengünstig in seiner Herstellung.According to Fig. 1 and 2 it can be seen that the spacer 11 increases in its width 17 from the first holding leg 12 connected to the post 3 to the second holding leg 13. The spacer 11 is thus trapezoidal, with its end width 18 corresponds to the first holding leg 12 of the width of the post 3. The spacer 11 is thus extremely material-saving and therefore inexpensive to manufacture.

Wie in Fig. 2 deutlich zu sehen, endet der zweite Halteschenkel in zwei Flansche 19 und 20 aus. Über diese Flansche 19 und 20 ist der Distanzhalter 11 mit den Schutzplanken 4, 5 fest verbunden, indem den jeweiligen Flansch 19 bzw. 20 und die Schutzplanken 4, 5 durchgreifende Schraubverbindungen 21 (bzw. im Allgemeinen Verbindungselemente) vorgesehen sind. Zudem ist der seitliche Abstand 22 zwischen den Flanschen 19 und 20 größer als die Breite des Pfostens 3, damit auf der Rückseite des Fahrzeugrückhaltesystems 1 vom Pfosten 3 ungehindert Montage- bzw. Wartungstätigkeiten an den Schraubverbindungen 21 vorgenommen werden können. Zudem ergeben sich durch konstruktive diese Maßnahme Kostenvorteile beim Herstellen des Distanzhalters 11, in dem ein Blechverschnitt minimiert wird. Der Halteschenkel 12 passt nämlich in die Lücke zwischen den beiden Flanschen 19, 20, was beim Abkantbiegeschritt eine im Verschnitt reduzierte Aneinanderreihung der Distanzhalter 11 erlaubt.As in Fig. 2 clearly visible, the second holding leg ends in two flanges 19 and 20. About these flanges 19 and 20 of the spacer 11 with the guard rails 4, 5 fixedly connected by the respective flange 19 and 20 and the guard rails 4, 5 cross-threaded connections 21 (or in general fasteners) are provided. In addition, the lateral distance 22 between the flanges 19 and 20 is greater than the width of the post 3, so that on the back of the vehicle restraint system 1 from the post 3 unhindered assembly and maintenance activities on the screw 21 can be made. In addition, this measure results in cost advantages in the manufacture of the spacer 11, in which a sheet metal waste is minimized. Namely, the holding leg 12 fits into the gap between the two flanges 19, 20, which allows a juxtaposed reduction of the spacers 11 in the folding bending step.

Der sich zwischen erstem und zweitem Halteschenkel 12, 13 ausbildende Haltesteg 23 des Distanzhalters 11 entspricht nahezu der maximalen Breite des Distanzhalters 11, was zu einer vergleichsweise hohen mechanischen Steifigkeit am Distanzhalter 11 führt. Der beispielsweise durch Öffnungen nicht unterbrochene und damit durchgehend ausgeführte Haltesteg 23 erhöht zudem diese mechanische Steifigkeit.The retaining web 23 of the spacer 11 forming between the first and second retaining limbs 12, 13 corresponds almost to the maximum width of the spacer 11, which leads to a comparatively high mechanical rigidity on the spacer 11. The uninterrupted, for example, through openings and thus Continuously running holding web 23 also increases this mechanical rigidity.

Auch wird diese Steifigkeit bzw. Formstabilität durch die Art und Weise der Flanschausbildung nicht beeinträchtigt, da diese beiden Flansche 19, 20 auf Abstand zum sich zwischen erstem und zweitem Halteschenkel 12, 13 ausbildenden Haltesteg 23 liegen.Also, this rigidity or dimensional stability is not affected by the manner of the flange formation, since these two flanges 19, 20 at a distance to form between the first and second retaining legs 12, 13 support web 23.

Gemäß Fig. 3 ist zu erkennen, das der sich der zwischen erstem und zweitem Halteschenkel 12, 13 ausbildende Haltesteg 23 auf Höhe des Plankenstegs 8 der Schutzplanke 4, 5 befindet. Dadurch ist eine hervorragende mechanische Kopplung zwischen Schutzplane und Pfosten geschaffen, um auch im Falle eines Fahrzeuganpralls ausreichenden Rückhalt von Fahrzeugen zu gewährleisten.According to Fig. 3 It can be seen that the of the first and second holding leg 12, 13 forming support web 23 at the level of the plank web 8 of the protective barrier 4, 5 is located. As a result, an excellent mechanical coupling between the tarpaulin and posts is created to ensure sufficient support of vehicles even in the event of a vehicle impact.

Wie der Fig. 2 weiter zu entnehmen, ist am ersten Halteschenkel 12 eine Montageöffnung 24 vorgesehen, die vom Verbindungselement 15 bzw. der Schraubverbindung durchgegriffen wird. Diese Montageöffnung 24 erweitert sich in ihrem Öffnungsquerschnitt 25 abschnittsweise, wodurch sich diese schlüssellochförmig ausgebildet. Eine anprallbedingte Verschiebung des Distanzhalters 11 kann damit das Lösen bzw. Ausknöpfen der festen Verbindung 14 erleichtern bzw. damit auch sicherstellen.Again Fig. 2 can be seen further, a mounting hole 24 is provided on the first holding leg 12, which is penetrated by the connecting element 15 and the screw. This mounting opening 24 widens in sections in its opening cross-section 25, thereby forming this keyhole-shaped. An impact-related displacement of the spacer 11 can thus facilitate the release or unbuttoning of the fixed connection 14 and thus also ensure.

Gerade der im überlappenden Stoßbereich 6 der Schutzplanken 4, 5 vorgesehene Distanzhalter 11 kann damit verhindern, dass die Verbindung zwischen den Schutzplanken 4, 5 durch die Steifigkeit des Pfostens 3 mechanisch beeinträchtigt wird. Die mechanische Verbindung im Stoßbereich 6 wird durch die Schraubverbindungen 21 des Distanzhalters 11 sowie durch weitere Schraubverbindungen 26 (bzw. im Allgemeinen Verbindungselemente) verstärkt ausgebildet. Zudem ist für zwei Schraubverbindungen 26 am Plankenschenkel 10 ein Verbindungsblech 27 vorgesehen, um diese mechanische Verbindung zu verstärken. Dieses Verbindungsblech 27 besteht bei allen Schraubverbindungen 26, wie dies in der Fig. 3 erkannt werden kann. Der Übersichtlichkeit halber wurde dies in den Figuren 1 und 2 nicht dargestellt.Especially in the overlapping joint area 6 of the guard rails 4, 5 provided spacers 11 can thus prevent the connection between the guard rails 4, 5 is mechanically impaired by the rigidity of the post 3. The mechanical connection in the joint area 6 is formed reinforced by the screw 21 of the spacer 11 and by further screw 26 (or in general fasteners). In addition, a connecting plate 27 is provided for two screw 26 on the plank leg 10 in order to strengthen this mechanical connection. This connecting plate 27 is in all screw 26, as shown in the Fig. 3 be recognized can. For the sake of clarity, this was in the FIGS. 1 and 2 not shown.

Der Schutzplankenstrang 7 kann damit eine hohe Belastung sicher abtragen und die Standfestigkeit des Fahrzeugrückhaltesystems 1 deutlich erhöhen.The protective barrier 7 can thus safely remove a high load and increase the stability of the vehicle restraint system 1 significantly.
