Abstract
Description
Die Erfindung betrifft ein Fahrzeugrückhaltesystem gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to a vehicle restraint system according to the features in the preamble of
Ein solches Fahrzeugrückhaltesystem zählt durch die
Das vorstehend beschriebene Fahrzeugrückhaltesystem soll insbesondere entlang von mit Hindernissen, wie insbesondere Bäumen, besäumten Straßen eingesetzt werden, damit ein aufprallendes Kraftfahrzeug sicher umgelenkt wird bzw. keine Sackbildung entsteht.The vehicle restraint system described above is intended in particular to be used along roads lined with obstacles, in particular trees, so that an impacting motor vehicle is reliably deflected or no bagging occurs.
Zum Stand der Technik zählt ferner das Fahrzeugrückhaltesystem der
Obwohl sich die bekannten Fahrzeugrückhaltesysteme in der Praxis in der überwiegenden Mehrzahl der Fälle bewährt haben, haftet ihnen dennoch die Eigenschaft an, dass bei Fahrzeugcrashs von Personenkraftwagen, die mit zu hoher Geschwindigkeit, also viel Energie, ablaufen, eine zu große Ausbeulung entsteht, was vor Bäumen zu einer Sackbildung führt.Although the known vehicle restraint systems have been proven in practice in the vast majority of cases, they nevertheless have the property that in car crashes of passenger cars that run at too high speed, so much energy, too bulging arises, what Trees leads to a sacking.
Neben der Aufhaltestufe ist der Wirkungsbereich W eine charakteristische Größe zur Beurteilung eines Fahrzeugrückhaltesystems. Als Wirkungsbereich W gilt der Abstand zwischen der dem Verkehr zugewandten Seite des Fahrzeugrückhaltesystems und der maximalen dynamischen seitlichen Position jedes wesentlichen Teils des Fahrzeugrückhaltesystems.In addition to the containment level, the effective range W is a characteristic variable for the evaluation of a vehicle restraint system. The effective range W is the distance between the traffic-facing side of the vehicle restraint system and the maximum dynamic lateral position of each essential part of the vehicle restraint system.
Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zu Grunde, das Aufhaltevermögen eines Fahrzeugrückhaltesystems gattungsgemäßer Art unter Vermeidung einer Sackbildung weiter zu verbessern.The invention is - based on the prior art - the object of the restraint of a vehicle restraint system generic type while avoiding bag formation to further improve.
Die Lösung dieser Aufgabe besteht nach der Erfindung in den Merkmalen des Anspruchs 1.The solution to this problem consists according to the invention in the features of
In diesem Zusammenhang ist es zunächst von Bedeutung, dass endseitig der Schenkel der Verstärkungsprofile voneinander weg gerichtete, an den Innenseiten der Flachschenkel der Schutzplanken anliegende Flansche vorgesehen sind. Damit stützen sich die Flachschenkel großflächig an den einen vergleichsweise großen vertikalen Abstand voneinander aufweisenden Flanschen der Verstärkungsprofile ab. Die Schutzplanken überlappen sich im Bereich eines Pfostens und sind hier unter Fixierung der Verstärkungsprofile über die Böden ihrer Längskanäle mindestens mittelbar mit den Pfosten sowie über ihre Flachschenkel mit den Flanschen der Verstärkungsprofile verschraubt. Auf diese Weise ist dafür Sorge getragen, dass sich die Verstärkungsprofile bei einem Fahrzeugcrash nicht unzulässig aufspreizen können und damit die Funktionstüchtigkeit des Fahrzeugrückhaltesystems beeinträchtigen.In this context, it is first of importance that the ends of the legs of the reinforcing profiles facing away from each other, are provided on the inner sides of the flat leg of the guard rails fitting flanges. Thus, the flat legs are based on a large area at a comparatively large vertical distance from each other having flanges of the reinforcing profiles. The guard rails overlap in the area of a post and are screwed here at least indirectly with the posts and their flanks with the flanges of the reinforcing profiles under fixation of the reinforcing profiles on the bottoms of their longitudinal channels. In this way, care is taken that the reinforcing profiles can not spread inadmissible in a vehicle crash and thus affect the functionality of the vehicle restraint system.
Die Überlappungsbereiche der Verstärkungsprofile sind demgegenüber in den Bereichen zwischen zwei aufeinander folgenden Pfosten vorgesehen und damit in Längsrichtung des Fahrzeugrückhaltesystems zu den Überlappungsbereichen der Schutzplanken versetzt angeordnet. Die Verstärkungsprofile sind hier über ihre Böden sowie über ihre Schenkel miteinander verschraubt. Auf diese Weise ist auch in den Überlappungsbereichen der Verstärkungsprofile eine ausreichende Längs-, Quer- und Verwindungssteifigkeit gegeben.In contrast, the overlapping areas of the reinforcing profiles are provided in the areas between two successive posts and thus arranged offset in the longitudinal direction of the vehicle restraint system to the overlapping areas of the protective barriers. The reinforcing profiles are bolted together over their bottoms and over their legs. In this way, sufficient longitudinal, transverse and torsional stiffness is given even in the overlapping areas of the reinforcing profiles.
Die Erfindung erlaubt es nunmehr, in besonderen Gefahrenstellen, wie zum Beispiel im Bereich von Bäumen, eine gezielte Versteifung eines Fahrzeugrückhaltesystems herbeizuführen. Eine unzulässige Sackbildung des Schutzplankenstrangs wird unterbunden. Die Insassen eines Fahrzeugs werden besser geschützt. Aber auch zu große Beschädigungen an einem an einem Crash beteiligten Fahrzeug werden vermieden.The invention now makes it possible to bring about targeted stiffening of a vehicle restraint system in special danger spots, for example in the area of trees. An inadmissible bagging of the protective barrier string is prevented. The occupants of a vehicle are better protected. But too much damage to a vehicle involved in a crash vehicle are avoided.
Aufgrund der bedarfsgerechten Gestaltung der Situation vor Ort in Kombination der Verstärkungsprofile und einer entsprechenden Anzahl bzw. Vielzahl von Pfosten wird eine harmonische und kontrollierte Umlenkung eines anprallenden Fahrzeugs erreicht. Das erfindungsgemäße Fahrzeugrückhaltesystem erreicht die Aufhaltestufe H2 und einen Wirkungsbereich W5 bei einem ASI-Wert (Acceleration Security Index) von unter 1.Due to the needs-based design of the situation on site in combination of reinforcing profiles and a corresponding number or variety of posts a harmonious and controlled deflection of an impacting vehicle is achieved. The vehicle restraint system according to the invention achieves the containment stage H2 and an effective range W5 with an ASI value (Acceleration Security Index) of less than 1.
Um ein geradliniges Aneinandersetzen aufeinanderfolgender Verstärkungsprofile zu gewährleisten, ist nach Anspruch 2 vorgesehen, dass im Überlappungsbereich zweier Verstärkungsprofile ein Endabschnitt eines Verstärkungsprofils um die Wanddicke der Verstärkungsprofile verkröpft ist. Auf diese Weise kann mithin das nicht verkröpfte Ende eines Verstärkungsprofils in das verkröpfte Ende eingebettet werden. Damit liegen die den Flachschenkeln der Schutzplanken zugewandten Seiten der Flansche der Verstärkungsprofile in einer Ebene.In order to ensure a rectilinear engagement successive reinforcing profiles, it is provided according to
Eine zusätzliche Versteifung des erfindungsgemäßen Fahrzeugrückhaltesystems in Längs- und Querrichtung wird mit den Merkmalen des Anspruchs 3 erreicht. Aufgrund des Sachverhalts, dass nunmehr in den Böden der Verstärkungsprofile mehrere in Längsrichtung zueinander versetzte Bohrungen vorgesehen sind, kann in Gefahrenbereichen, wie zum Beispiel in der Nähe von Bäumen, die jeweils zweckmäßige Anzahl an Pfosten gesetzt, damit in möglichst geringem Abstand zueinander angeordnet und mit den Verstärkungsprofilen verbunden, insbesondere verschraubt, werden.An additional stiffening of the vehicle restraint system according to the invention in the longitudinal and transverse directions is achieved with the features of
Die Verstärkungsprofile können mit einer Lochreihe versehen sein, bei dem werks- bzw. herstellerseitig alle 30 cm bis 40 cm eine Bohrung vorgesehen ist. Grundsätzlich können die Bohrungen aber auch vor Ort auf der Baustelle erzeugt werden, um die Verstärkungsprofile an den Pfosten festzulegen. Die Pfosten können dann entsprechend den örtlichen Gegebenheiten in den Boden gerammt werden, um beispielsweise Wurzeln oder Steine im Erdreich zu umgehen.The reinforcing profiles can be provided with a row of holes, in the factory or manufacturer side every 30 cm to 40 cm a hole is provided. In principle, however, the bores can also be produced on site at the construction site in order to fix the reinforcement profiles to the posts. The posts can then according to local conditions in the ground be rammed, for example, to avoid roots or stones in the ground.
Zur Berücksichtigung der Kopfdicke der der Verbindung von zwei Verstärkungsprofilen dienenden Schraubbolzen ist nach Anspruch 4 vorgesehen, dass zwischen die Böden der Längskanäle der Schutzplanken und die Pfosten Distanzstücke eingegliedert sind. Die Distanzstücke können aus Stahl oder Kunststoff gebildet sein.To take into account the head thickness of the connection of two reinforcing profiles serving bolts is provided according to
Das Aufhaltevermögen des Fahrzeugrückhaltesystems wird mit den Merkmalen des Anspruchs 5 weiter verbessert. Dadurch, dass die Schutzplanken mit den Verstärkungsprofilen in diversen Querebenen jeweils über drei Punkte verbunden sind, wird mit dieser Bauart ein Federverhalten erreicht, bei welchem sich die Konstruktion im Moment eines Kraftfahrzeugaufpralls verformt, dann wieder elastisch entspannt und letztlich das Fahrzeug zurückstellt.The stoppage of the vehicle restraint system is further improved with the features of
Die erfindungsgemäße Ausbildung hat zur Foge, dass gemäß Anspruch 6 die Schutzplanken dünner als die Verstärkungsprofile ausgeführt sein können.The training according to the invention has to Foge that according to
Auch das größere Spiel der Schraubbolzen in den Bohrungen (Anspruch 7) kann bei einem Aufprall zum Abbau der Energie beitragen.Also, the larger game of bolts in the holes (claim 7) can contribute to the reduction of energy in an impact.
Der Montageerleichterung des erfindungsgemäßen Fahrzeugrückhaltesystems dienen die Merkmale des Anspruchs 8. Danach weisen die Pfosten einen sigmaförmigen Querschnitt auf. In den Schenkeln der Pfosten oder in den den Schutzplanken zugewandten Abschnitten der Abstandshalter sind Bohrungen zur Aufnahme eines Montagewerkzeugs vorgesehen. Dieses Montagewerkzeug kann aus einem einfachen Rundstab bestehen, der bei der Montage der Verstärkungsprofile durch diese Bohrungen gesteckt wird. Fahrbahnseitig steht das Montagewerkzeug über die Pfosten oder die Abstandshalter vor, so dass die Verstärkungsprofile zunächst auf diese Rundstäbe gefädelt werden können, ohne dass die Monteure während der weiteren Montage die Verstärkungsprofile manuell in einer bestimmten Höhe halten müssen. Die aufeinander folgenden Verstärkungsprofile können dann miteinander verschraubt werden. Anschließend werden die Schutzplanken mit den Pfosten oder den Abstandshaltern und den Flanschen der Verstärkungsprofile verschraubt.The mounting relief of the vehicle restraint system according to the invention serve the features of
