Description
Leit- (oder Schutz-) Planken leiten den fließenden Verkehr und schützen die sich hinter ihnen befindlichen Objekte, wobei bei Aufprall eines Verkehrsteilnehmers eine winkelabhängige Zurückweisung auf die Fahrbahn erfolgt. Aufgrund der üblicher Weise starren Bauweise der Leitplanken ergeben sich in Abhängigkeit von Geschwindigkeit und Masse mehr oder weniger große Deformationen am Schutzsystem und an den Fahrzeugen.conductivity (or protective) planks guide the flowing traffic and protect the behind them objects, whereby upon impact of a Road user an angle-dependent rejection on the road he follows. Because of the usual way rigid construction of the guardrails arise in dependence of speed and mass more or less large deformations on the protection system and on the vehicles.
Diese Deformationen erzeugen zwar eine bauartlich bedingte Knautschwirkung; die Beeinträchtigung der Kfz- Insassen wird dabei aber gar nicht oder nur unbefriedigend gedämpft. Im PKW versuchen die installierten Rückhaltesystem diesen Umstand auszugleichen, – anders als bei Zweiradfahrzeugen. Hierbei werden Fahrer und Fahrzeug meist getrennt auf die Fahrbahn geschleudert, wobei oft irreparable Deformationen am Krad erfolgen und der Körper des Fahrers die Dämpfung beim Aufprall in vollem Umfang zu erbringen hat,- ein wesentliches Merkmal vieler schwerer Motorradunfälle.These Although deformations produce a construction-related Knautschwirkung; the impairment However, the vehicle occupant is not at all or only unsatisfactory attenuated. In cars, the installed restraint system try this circumstance compensate, - different as with two-wheeled vehicles. This driver and vehicle are usually separated Flung on the road, often irreparable deformations done on the bike and the body the driver's damping has to perform fully on impact, - an essential feature many serious motorcycle accidents.
Diese Starrheit üblicher Leitsysteme hat zudem zur Folge, dass bereits bei leichtem Auffahren mit geringer Geschwindigkeit wie auf der Straße aber auch bei Ein- und Ausfahrten in Parkhäusern zu verzeichnen, erhebliche Beschädigungen an den Fahrzeugen auftreten; all zu oft werden so z.B. beim Bedienen der Kartensysteme in Parkhäusern den PKW teure Beschädigungen zugefügt, die bei flexibleren Leitsystemen vermeidbar wären.These Rigidity more usual In addition, guidance systems have the consequence that they start with light starting low speed as on the road but also at entry and exit in parking garages Significant damage occur on the vehicles; all too often, e.g. when operating of the card systems in parking garages the car expensive damage added which would be avoidable with more flexible control systems.
Sicherlich könnten Leitsysteme gefordert und geschaffen werden, die ein höheres Maß an Energieabbau ohne Verletzungen und Beschädigungen gewährleisten. Doch die Durchsetzung eines Austauschs unendlich vieler Kilometer an den Straßen und/oder im Parkraum ist gewiss nicht durchsetzbar. Somit ist ein kostengünstiges Nachrüstsystem wünschenswert, dessen Elemente durch modularen Aufbau an allen Formen installierter Leitplanken nachträglich angebracht werden können.Definitely could Control systems are required and created, which requires a higher level of energy reduction without injury or damage. But the implementation of an exchange of endless kilometers on the streets and / or in the parking area is certainly not enforceable. Thus, a cost-effective retrofit system desirable, whose elements are installed by modular construction on all forms Guard rails later can be attached.
In Deutschland und vielen Ländern Europas ist ein genormter Typ von Leitplanken aus verzinktem Stahl anzutreffen. Die hier beschriebene Erfindung sieht vor, die Frontfläche mit einem geeigneten Schaumstoff so aufzufüttern bzw. zu „polstern", dass eine anteilige Aufpralldämpfung erfolgt, die in vielen der o.a. Fälle einen beschädigungslosen und verletzungsminimierenden Ausgang erwarten lässt. Hierzu eignet sich in besonderem Maße ein Polypropylen-Schaumstoff, der auch in Stoßfängersystemen im Automobil sein Energieabsorptionsvermögen und seine mechanische Belastbarkeit bewiesen hat und zudem durch große Witterungsbeständigkeit gekennzeichnet ist.In Germany and many countries Europe is a standardized type of guardrail made of galvanized steel encountered. The invention described here provides the front surface with a suitable foam so to feed or "cushion" that a pro-rata shock absorption done in many of the o.a. Cases a damageless and injury-minimizing outcome. This is suitable in special size a polypropylene foam, which is also used in automotive bumper systems Energy absorption capacity and has proved its mechanical strength and also by size weatherability is marked.
Gegenstand dieser Erfindung ist somit ein modulares Aufprall-Dämpfungs-System für die (ggf. nachträgliche) Anbringung an Schutz- bzw. Leitplanken, das die herkömmliche Formenvielfalt ganzheitlich abdeckt und die Gefahr von Blechschäden im unteren Geschwindigkeitsbereich sowie von vielen Motorrad-Unfälle deutlich verringert.object This invention is thus a modular impact-damping system for the (possibly subsequent) Attachment to guardrails, which is the conventional Comprehensively covers the diversity of forms and the danger of sheet metal damage in the lower part Speed range as well as many motorcycle accidents clearly reduced.
Die
hierzu erforderlich Dämpfungselemente (
Für Straßenstellen, an denen eine erhöhte Gefahr für Motorrad-Fahrer besteht unter die Leitplanken geschleudert zu werden, können dieselben Sicherheits-Elemente auch verwendet werden, um den Raum unter (oder über) der installierten Leitplanke zusätzlich abzusichern.For street posts, where an increased risk for motorcycle riders is to be thrown under the guardrails, the same security elements Also used to move the space under (or over) the installed guardrail additionally secure.
