Description

Die vorliegende Erfindung betrifft einen aus mehreren Schichten aufgebauten Schutzhelm.The present invention relates to one of several Layers of hard hat.

Schutzhelme, wie sie von z.B. Motorradfahrern und Ski­ rennfahrern verwendet werden, sollen den Kopf im Falle ei­ nes Unfalls vor Verletzungen schützen.Protective helmets, e.g. Motorcyclists and skis racers should be used in the case of egg Protect an accident from injury.

Die bekannten Helme haben eine dicke, sehr harte Außen­ schicht und eine mehr oder weniger weiche, einfache Innen­ polsterung, die nach innen mit einer Leder- oder Kunststoff­ haut überzogen ist. Durch diese Helme wird der Kopf zwar vor dem direkten Schlag geschützt; aufgrund der mangelhaf­ ten Dämpfung und durch die oft ebenfalls harte Innenpolste­ rung wirkt die Aufprallwucht nur wenig vermindert auf den Kopf ein. Dies gilt um so mehr, je härter die Außenschale ist; dieses ist gerade bei den neuen Schutzhelmen mit einer dickeren und versteiften Außenschale der Fall. Ein weiterer Nachteil der bekannten Schutzhelme ist die schlechte Schwer­ punktsverteilung, da die äußere Schicht üblicherweise schwer ist.The well-known helmets have a thick, very hard exterior layer and a more or less soft, simple interior padding on the inside with a leather or plastic skin is covered. With these helmets, the head is protected from the direct blow; due to inadequate damping and the often hard inner pads impact force is only slightly reduced on the Head on. This applies the more, the harder the outer shell is; this is especially the case with the new protective helmets with one thicker and stiffened outer shell the case. Another The disadvantage of the well-known protective helmets is the poor heavy point distribution since the outer layer is usually is difficult.

Der Erfindung liegt daher die Aufgabe zugrunde, einen verbesserten Schutzhelm zu schaffen, der die von außen auf den Helm einwirkende Kraft besser dämpft und gleichzeitig eine bessere Schwerpunktsverteilung aufweist.The invention is therefore based on the object to create improved hard hat that is on the outside dampens the force of the helmet better and at the same time has a better distribution of the center of gravity.

Die Aufgabe wird erfindungsgemäß durch einen Schutz­ helm gelöst, der sandwichartig aus mehreren Schichten auf­ gebaut ist, wobei der Härtegrad der Schichten von außen nach innen von Schicht zu Schicht zunimmt. Die äußerste dünne Schicht, die z.B. aus PVC besteht, hat lediglich die Aufgabe, den Helm außen abzuschließen und vor Schmutz, Feuchtigkeit etc. zu schützen; sie umschließt den erfin­ dungsgemäßen Helm. Danach kommen mehrere Schutzschichten mit zunehmenden Härtegraden, wobei erfindungsgemäß, abge­ sehen von der äußersten Schutzschicht, die weichste Schicht außen und die härteste innen liegt. Die zweite und die dritte Schicht sollen dabei aus vorzugsweise Kunststoff- Luftkissen zunehmender Festigkeit und Härte, die vierte, fünfte und sechste aus Schaumstoff zunehmender Härte und die siebte aus Kunststoff vorzugsweise aus PVC oder GfK be­ stehen. Die achte Schicht, die wiederum beispielsweise aus Schaumstoff besteht, polstert den Kopf weich ab und ist von einer Leder- oder Kunststoffschicht überzogen.The object is achieved by protection helmet loosened, the sandwich-like on several layers is built, the degree of hardness of the layers from the outside increases from layer to layer inside. The outermost thin layer, e.g. is made of PVC, only has Task to lock the helmet outside and from dirt, Protect moisture etc.; it encloses the inventor proper helmet. Then several protective layers come  with increasing degrees of hardness, whereby according to the invention, abge see from the outermost protective layer, the softest layer outside and the hardest is inside. The second and the third layer should preferably be made of plastic Air cushions of increasing strength and hardness, the fourth, fifth and sixth made of foam increasing hardness and the seventh plastic, preferably PVC or GRP stand. The eighth layer, which in turn consists of There is foam, softly cushions the head and is covered with a layer of leather or plastic.

Durch den erfindungsgemäßen Schichtenaufbau ist ge­ währleistet, daß die auf den Helm von außen einwirkende Kraft zuerst von der flexiblen Außenschicht und der äußer­ sten weichsten Schutzschicht aufgefangen wird, wobei es bei starken Krafteinwirkungen eventuell zu einem Platzen der Luftkissen kommt. Die verbleibende Aufprallenergie wird an die zweite härtere Schutzschicht weitergegeben, die dabei wiederum verbleibende Energie geht an die dritte, nochmals härtere Schicht usw. Vor extrem harten Schlägen und spitzen oder kantigen Gegenständen schützt dann im Ex­ tremfall immer noch die sehr harte Innenschicht, welche mit der harten Außenschicht bisher bekannter Helme zu ver­ gleichen ist. Auf diese Weise wird der Kopf geschützt und vor allem aber wird die Aufprallkraft wesentlich gedämpft.Due to the layer structure according to the invention, ge ensures that the one acting on the helmet from the outside Force first from the flexible outer layer and the outer softest protective layer is collected, whereby it bursting with strong forces the air cushion comes. The remaining impact energy is passed on to the second harder protective layer, the remaining energy goes to the third, even harder layer, etc. Before extremely hard blows and sharp or angular objects then protects in ex tremfall still the very hard inner layer, which with the hard outer layer of previously known helmets same is. In this way the head is protected and but above all, the impact force is significantly dampened.

Ferner hat der erfindungsgemäße Schutzhelm gegenüber bisher bekannten Schutzhelmen den Vorteil einer besseren Schwerpunktsverteilung, da die leichten Schichten außen und die schweren innen liegen.Furthermore, the protective helmet according to the invention has previously known protective helmets have the advantage of a better one Center of gravity because the light layers outside and the heavy ones are inside.

Im folgenden wird die Erfindung anhand der Figuren nä­ her erläutert:In the following the invention is based on the figures explained here:

Fig. 1 zeigt eine schematische Darstellung des erfin­ dungsgemäßen Schutzhelms. Im hinteren Helmbereich wurde ein Längsschnitt angebracht, um die Schichtung sichtbar zu ma­ chen. Fig. 1 shows a schematic representation of the protective helmet inventions to the invention. A longitudinal cut was made in the rear area of the helmet to make the layering visible.

Fig. 2 zeigt den in Fig. 1 markierten Schichtbereich in der Vergrößerung. FIG. 2 shows the layer region marked in FIG. 1 in an enlargement.

Fig. 3 zeigt eine schematische Darstellung der bevor­ zugten Luftkissenschichten in der Draufsicht. Fig. 3 shows a schematic representation of the preferred air cushion layers in plan view.

Der erfindungsgemäße Schutzhelm, wie er in Fig. 1 dar­ gestellt ist, wobei der Schutzhelm genauso gut im Nacken stärker abgerundet, oder im Stirnbereich stärker gewölbt sein kann, umschließt den Hinterkopf und die Kinnpartie, wobei für das Gesicht eine Öffnung vorhanden ist, über die ein üblicherweise seitlich angelenktes Visier klappbar ist.The protective helmet according to the invention, as it is shown in Fig. 1, wherein the protective helmet may be more rounded in the neck, or may be more curved in the forehead area, encloses the back of the head and the chin, with an opening for the face over which a visor that is usually hinged to the side is foldable.

Der Schutzhelm besteht, wie in Fig. 1 oder 2 darge­ stellt aus bevorzugt neun Schichten. Schicht 1 hat eine Dicke von 1 bis 2 mm und besteht aus elastischem, stabi­ len Kunststoff, beispielsweise PVC, Schicht 2 und 3 sind aus Kunststoffluftkissen aufgebaut und haben eine Dicke von 10 bis 15 mm. Wie aus Fig. 3 ersichtlich, ist die Wandstärke von Schicht 3 gegenüber Schicht 2 ver­ doppelt. Schichten 4, 5 und 6 bestehen aus Schaumstoff und haben eine Dicke von ca. 10 bis 15 mm; die Materialhärte steigt vorzugsweise entsprechend zunehmenden Raumgewichten von vorzugsweise 60 über 120 auf 240. Schicht 7, die Innen­ schale, hat eine Dicke von ca. 4 bis 5 mm und besteht aus stabilem bruchsicheren Kunststoff, bevorzugt aus PVC oder GfK. Schicht 8 besteht aus 10 bis 15 mm dickem Schaumstoff, dessen Raumgewicht bei etwa 120 liegt. Schicht 9, die Innen­ verkleidung, ist eine dünne Haut aus Kunststoff oder Leder.The protective helmet consists, as in Fig. 1 or 2 Darge, preferably consists of nine layers. Layer 1 has a thickness of 1 to 2 mm and is made of elastic, stable plastic, for example PVC, layers 2 and 3 are made of plastic air cushions and have a thickness of 10 to 15 mm. As seen from Fig. 3, the wall thickness of layer 3 with respect to layer 2 is twice ver. Layers 4 , 5 and 6 consist of foam and have a thickness of approximately 10 to 15 mm; the material hardness preferably increases in accordance with increasing densities from preferably 60 to 120 to 240. Layer 7 , the inner shell, has a thickness of approximately 4 to 5 mm and is made of stable unbreakable plastic, preferably PVC or GfK. Layer 8 consists of 10 to 15 mm thick foam, the density of which is approximately 120. Layer 9 , the inner lining, is a thin skin made of plastic or leather.
