Abstract
Description
Normgerechte Motorradschutzhelme bestehen aus einer Außenschale, im Regelfall aus Glasfaserkunststoff, einem Kern aus Styropor als eigentlich schlagdämpfendem Element und einem Innenfutter aus Stoff.Standard-compliant motorcycle helmets consist of an outer shell, usually made of fiberglass, a core made of polystyrene as a shock absorbing element and a fabric lining.
Motorradschutzhelme entsprechen in der Form ihrer Innenschale (Kopfauflageseite) einem Normkopf, der im Regelfalle durch keinen potentiellen Träger erbracht wird. So kommt es im Bereich zwischen Helmschale und Kopf immer wieder zur Bildung von Zwischenräumen. Diese Zwischenräume führen bei einem Sturz/Schlag zu Druckspitzen auf die eng anliegenden Kopfpartien und verhindern eine gleichmäßige Energieverteilung zur Verarbeitung der auftreffenden Schlagenergie. Folge hiervon sind immer wieder schwere Verletzungen, trotz ausreichender Helmqualität.Motorcycle protective helmets correspond in shape to theirs Inner shell (head support side) a standard head that in As a rule, no potential sponsor provides this. So it always happens in the area between the helmet shell and head again to form gaps. These spaces lead to pressure peaks on the tight in the event of a fall / impact adjacent head areas and prevent an even Energy distribution for processing the incoming Impact energy. The consequences of this are always serious Injuries, despite adequate helmet quality.
Gedacht ist, zwischen Helmschale und Kopf einen variablen Distanzausgleich einzubringen. Dieser soll nach dem Anlegen des Helmes diese Zwischenräume ausgleichen und so für eine gleichmäßigere Verteilung auftreffender Energiemengen sorgen. Der Inhalt dieses Distanzausgleiches muß über eine hohe Schlagdämpfungseigenschaft verfügen und wird hierzu mit einem Gel gefüllt werden. In Verbindung mit Helmschale, Styropor-Kern, Distanzausgleich und Frottee-Innenfutter wird so ein kompakter und gleichmäßiger Schlagdämpfungs schutz erreicht. Is intended to be a variable between the helmet shell and head Distance compensation. This should be after the creation of the helmet compensate for these gaps and so for one more even distribution of incoming energy to care. The content of this distance compensation must have a have high shock absorption properties and will do so be filled with a gel. In connection with helmet shell, Styrofoam core, distance compensation and terry lining becomes a compact and even shock absorption protection achieved.
Aufbau in Grundform (Fig. 1a/b) mit je vier Lappen für Kopf oberseite (1), rechte und linke Kopfseite (2) und Hinterkopf (3). Die vier Lappen münden in einem Zentrum (4), daß im Helm später so positioniert wird, daß es im Bereich der kleinen Fontanelle des Schädels eines Trägers liegt.Structure in basic form ( Fig. 1a / b) with four tabs each for the top side ( 1 ), right and left side of the head ( 2 ) and back of the head ( 3 ). The four lobes end in a center ( 4 ) that is later positioned in the helmet so that it lies in the area of the small fontanel of a wearer's skull.
Die Lappen und das Zentrum sind aus PVC-Klarsichtfolie (Fig. 2, 1, 4, 6), ca. 0,2 mm stark, gearbeitet. Sie sind dreifach gearbeitet (Fig. 2), so das es zur Bildung von zwei Kammern (2/5) kommt.The flaps and the center are made of transparent PVC film ( Fig. 2, 1, 4, 6), approx. 0.2 mm thick. They are worked in triplicate ( Fig. 2), so that two chambers ( 2/5 ) are formed.
Die obere, am Styropor-Kern anliegende Kammer (2) ist durch Abschweißungen (3) labyrinthartig unterteilt und mit Luft oder einem anderen Stoff gefüllt. Über einen am Zentrum beginnenden PVC-Schlauch (Fig. 1a/b, 4) wird eine Verbindung zu einem, mit dem gleichen Stoff gefüllten Reservoir (Fig. 1a/b, 6) hergestellt. Mittels einer Pumpe und einem Ventilsystem kann das Volumen des Stoffes in der oberen Kammer variiert werden.The upper chamber ( 2 ) lying against the styrofoam core is divided by labyrinthine welds ( 3 ) and filled with air or another substance. A PVC hose ( Fig. 1a / b, 4) beginning at the center is used to connect to a reservoir ( Fig. 1a / b, 6) filled with the same substance. The volume of the substance in the upper chamber can be varied by means of a pump and a valve system.
Die untere, der Kopfseite aufliegenden Kammer (5) ist mit einem viskosen Gel oder einem elastischen Kunststoff gefüllt. Bei gleichmäßiger Verteilung des Stoffes in dieser Kammer soll eine ca. Stärke von 2-3 mm erreicht werden.The lower chamber ( 5 ) lying on the head side is filled with a viscous gel or an elastic plastic. If the material is evenly distributed in this chamber, an approximate thickness of 2-3 mm should be achieved.
Das Gesamtgewicht der Konstruktion soll unter 300 g liegen und sie soll so angelegt werden, daß keine Behinderung eventuell vorhandener Entlüftungseinrichtungen des Motor radschutzhelms entstehen.The total weight of the construction should be less than 300 g and it should be laid out so that no disability any existing ventilation devices of the engine protective helmets arise.
