Abstract

The invention concerns an impact neutralizer intended to protect parts of the human body and designed in the form of a cushion of plastics material. The impact neutralizer is a body (8) made of synthetic-polymer material in which particles (12, 14, 16) are embedded which can be destroyed by an impact and/or absorb the energy of impact.

Description

Stoßneutra LisatorShock-neutral Lisator
Die Erfindung betrifft einen Stoßneutrali sator zum Schutz menschlicher Körpertei le in Form eines Polsters aus Kuns stoff .The invention relates to a shock neutral to protect human body parts le in the form of a cushion made of plastic.
Es ist bekannt, daß insbesondere Motorradfahrer Schutzbekleidungen verwenden, wie ein- oder mehrtei lige Anzüge, die aus Leder und/oder synthetischem Material bestehen. Diese Schutzbekleidungen bieten weitgehenden Schutz bei einem Sturz dadurch, daß die am meisten gefährdeten Körpertei le durch entsprechende Stoßneut ra l i satoren geschützt werden. Durch diese in die Schutzbekleidung integrierten Stoßneutralisatoren wird insbesondere die Gefahr von Prellungen und Schürfve r let zungen verringert. Ein wesentlicher Nachtei l der bekannten Stoßneut ra l i satoren besteht darin, daß sie ein erhebliches Volumen aufweisen müssen, um die zu erwartenden Stöße annähernd vollständig auffangen zu können. ies hat jedoch zur Folge, daß die Schutzbekleidungen im Bereich der Stoßneutralisatoren voluminös und somit auch nicht besonders ansehnlich sind. Schließlich ist noch von Bedeutung, daß die bekannten Stoßneutralisatoren wenig flexibel sind und dem jewei ligen Körpertei l angepaßt werden müssen. Ausgehend von dem obigen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den gattungsgemäßen Stoßneutral sator so weiterzubilden, daß er bei besonders guten ämpfungseigenschaften e n verhältnismäßig geringes Volumen einnimmt und problemlos herstellbar ist.It is known that in particular motorcyclists use protective clothing, such as one-piece or multi-part suits made of leather and / or synthetic material. These protective clothing offers extensive protection in the event of a fall by the most vulnerable parts of the body being protected by appropriate shock-neutralizers. These shock neutralizers integrated in the protective clothing reduce in particular the risk of bruises and abrasions. An important disadvantage of the known shock neutrators is that they must have a considerable volume in order to be able to absorb the expected impacts almost completely. However, this has the consequence that the protective clothing in the area of the shock neutralizers is voluminous and therefore not particularly attractive. Finally, it is also important that the known shock neutralizers are not very flexible and must be adapted to the respective body part. Based on the above prior art, the invention has for its object to further develop the generic shock neutral sator so that it takes up relatively small volume with particularly good damping properties and is easy to manufacture.
Die gestellte Aufgabe wird beim gattungsgemäßen Stoßneutralisator erfindungsgemäß durch einen aus polymerem Kunststoff bestehenden Körper gelöst, in dem Partikel eingebettet, sind, die beim Stoß zerstörbar sind und/oder Stoßenergie aufnehmen.The object is achieved in the generic Stoßneutralisator according to the invention by a group consisting of polymeric plastic body, embedded in the particles are which are destroyed upon impact and / or absorb the impact energy.
Man erkennt, daß die Erfindung jedenfalls dann verwirklicht ist, wenn der eigentliche Stoßneutralisator aus energieaufnehmenden oder beim Stoß in ihrer Struktur zerstörbaren Partikeln besteht, die in einem polymeren Kunststoff eingebettet sind und sich somit den Besonderheiten des zu schützenden Körperteils problemlos anpassen können. Die eigentliche Energieabsorbtion erfolgt dadurch, daß die Partikel, z.B. Granulat, Kügelchen oder andere kleine Formen aufweisende Teilchen des Polysti rol-Schaumstoffs oder Korks, beim Aufprall nicht unbedingt elastisch verformt, sondern eher zerstört werden. Die Aufprallenergie wird daher in Zerstörrungsenergie der Partikel umgewandelt. Die Partikel sind zweckmäßigerweise sehr klein.It can be seen that the invention is implemented in any case when the actual shock neutralizer consists of energy-absorbing or structure-destructible particles which are embedded in a polymeric plastic and can therefore adapt easily to the characteristics of the body part to be protected. The actual energy absorption takes place in that the particles, e.g. Granules, beads or other small particles of polystyrene foam or cork that do not necessarily become elastically deformed on impact, but are rather destroyed. The impact energy is therefore converted into the destruction energy of the particles. The particles are expediently very small.
Weitere zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further expedient and advantageous refinements of the invention emerge from the subclaims.
Eine besonders zweckmäßige Ausgestaltung sieht vor, daß der Korper aus Polyurethan besteht, während die Partikel aus Styropor gebildet sind. Im Rahmen dieses Erfindungsgedankens ist es besonders zweckmäßig, wenn der Körper aus geschäumtem Polyurethan besteht. Um den Stoßneut ra l i sator problemlos in Jacken bzw. Anzüge einbringen zu können, sieht eine weitere zweckmäßige Ausgestaltung der Erfindung vor, daß das Polster die Form einer Platte besitzt, deren Fläche größer ist als die Fläche des zu schützenden Körpertei les. Um das Körpertei l opti al schützen zu können, ist es zweckmäßig, wenn das Polster partiell unterschiedliche Dicken aufweist, wobei die dickeren Abschnitte in diesem Bereich des zu schützenden Körpertei ls angeordnet sind, wo die Hauptbelastungen des Körpertei les zu erwartens sind. Der wesentliche Vortei l der Erfindung besteht somit nicht nur in der einfachen und problemlosen Herstellung des Stoßneutral isators, sondern auch in der Tatsache, daß er extrem leicht ist, und zwar vor allem dann, wenn es sich um einen Körper aus geschäumten Polyurethan handelt. Da der Stoßneut ra l i sator verformbar ist, muß er nicht schon während seiner Herstellung die Besonderheiten des zu schützenden Körpertei ls berücksichtigen. Für alle zu schützenden Körpertei le kann vielmehr ein Stoßneut ra l i sator hergestellt und sodann zugeschnitten werden .A particularly useful embodiment provides that the body is made of polyurethane, while the particles are made of styrofoam. As part of this The idea of the invention is particularly expedient if the body consists of foamed polyurethane. In order to be able to easily introduce the shock-neutralizer into jackets or suits, a further expedient embodiment of the invention provides that the cushion has the shape of a plate, the area of which is larger than the area of the body part to be protected. In order to be able to protect the body part optically, it is expedient if the pad has partially different thicknesses, the thicker sections being arranged in this region of the body part to be protected, where the main loads on the body part are to be expected. The essential advantage of the invention is therefore not only the simple and problem-free manufacture of the shock-neutral isator, but also the fact that it is extremely light, especially when it is a body made of foamed polyurethane. Since the impact resizer is deformable, it does not have to take the special features of the body part to be protected into account during its manufacture. For all parts of the body that are to be protected, a shock absorber can rather be produced and then cut to size.
In der Zeichnung ist ein E L Ibogens c hutz 10 dargestellt, der aus Kunststoff besteht und in dem Partikel 12, 14, 16 aus Po lyst i ro l-Schaumstoff eingebettet sind. Der Ellbogenschutz ist der Form des Benutzerellbogens angepaßt, jedoch elastisch verformbar. Lm Körper 8 sind die Partikel 12, 14, 16 in etwa gleichmäßig vertei lt. Die Besonderheit der als Mikrotei lchen ausgebi ldeten Partikel besteht darin, daß sie beim Stoß entweder zerstört oder elastisch verformt werden. Dabei kann es auch zur Änderung der Anordnung der Partikel innerhalb des Körpers 8 kommen. Denn der Körper 8 ist nicht nur ein Träger der Partikel 12, 14, 16, sondern auch ein Bindemittel, das mit den Partikeln elastisch verbunden ist. Wird nun auf den Stoßneutralisator Kraft ausgeübt, verformt er sich elastisch, wobei die Partikel innerhalb des Körpers zerstört, verdrängt oder verformt werden können. In the drawing, an EL Ibogens protector 10 is shown, which consists of plastic and in which particles 12, 14, 16 made of polystyrene foam are embedded. The elbow protection is adapted to the shape of the user elbow, but is elastically deformable. The particles 12, 14, 16 are distributed approximately uniformly in the body 8. The peculiarity of the particles formed as microparticles is that they either destroy or elastically deform them on impact become. The arrangement of the particles within the body 8 can also change. Because the body 8 is not only a carrier of the particles 12, 14, 16, but also a binder that is elastically connected to the particles. If force is now exerted on the shock neutralizer, it deforms elastically, whereby the particles inside the body can be destroyed, displaced or deformed.
