Description

Die Erfindung betrifft einen Lawinen-Schutzhelm.The invention relates to an avalanche safety helmet.

Aus der EP 1 998 639 B1 ist einen Lawinen-Rettungshelm bekannt. Der Helm ermöglicht einem Lawinen-Unfallopfer mittels eines Beatmungssystems sauerstoffhaltige Luft aus dem Schnee zu atmen und kohlendioxidhaltige, ausgeatmete Luft mittels eines Schlauchsystems aus dem Helm abzuleiten. Ein derartiger Helm ist aufwändig konstruiert mit integrierten Luftleitkanälen und einem an den Helm angeschlossenen Schlauch. Insbesondere ist der Tragekomfort für einen Skifahrer beeinträchtigt.From the EP 1 998 639 B1 is known an avalanche rescue helm. The helmet allows an avalanche victim to breathe oxygen-containing air out of the snow by means of a respiratory system and to discharge carbon dioxide-containing, exhaled air out of the helmet by means of a hose system. Such a helmet is elaborately constructed with integrated air ducts and a hose connected to the helmet. In particular, the wearing comfort is impaired for a skier.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Lawinen-Schutzhelm zu schaffen, der es einem Lawinen-Unfallopfer ermöglicht, über einen längeren Zeitraum Atemluft zur Verfügung zu stellen, wobei der Schutzhelm insbesondere unkompliziert aufgebaut ist.Based on this, the object of the invention is to provide an avalanche safety helmet which enables an avalanche victim to provide breathing air over a relatively long period of time, the safety helmet being constructed particularly uncomplicated.

Diese Aufgabe ist durch einen Lawinen-Schutzhelm mit den Merkmalen nach Anspruch 1 gelöst. Erfindungsgemäß wurde erkannt, dass ein Kohlendioxid-Absorber es ermöglicht, in der ausgeatmeten Luft enthaltenes Kohlendioxid aufzunehmen und zu binden. Dadurch ist es möglich, Kohlendioxid aus einem Luftreservoir, das bei einer Lawinenverschüttung begrenzt ist, zu filtern. Die verbleibende Atemluft kann von dem Lawinen-Unfallopfer mehrfach geatmet werden. Bei jeder Atmung wird nur ein geringer Anteil des in der Atemluft enthaltenen Sauerstoffs verbraucht. Die Überlebensdauer eines Lawinen-Unfallopfers ist dadurch verlängert. Dadurch, dass der Kohlendioxid-Absorber aktivierbar ist, ist gewährleistet, dass der Kohlendioxid-Absorber frisch und unverbraucht ist, solange er nicht aktiviert worden ist. Es ist insbesondere möglich, den Lawinen-Schutzhelm über eine längere Nutzungsdauer zu nutzen, ohne dass der Kohlendioxid-Absorber in seiner Funktion eingeschränkt ist. Der Lawinen-Schutzhelm ist insbesondere unkompliziert aufgebaut und dadurch kostengünstig herstellbar.This object is achieved by an avalanche safety helmet with the features of claim 1. According to the invention, it has been recognized that a carbon dioxide absorber makes it possible to absorb and bind carbon dioxide contained in the exhaled air. This makes it possible to filter carbon dioxide from an air reservoir that is limited in an avalanche burial. The remaining breathing air can be breathed several times by the avalanche accident victim. With each respiration, only a small portion of the oxygen contained in the breathing air is consumed. The survival time of an avalanche accident victim is thereby extended. Thereby, that the carbon dioxide absorber is activated, it is ensured that the carbon dioxide absorber is fresh and unused, as long as it has not been activated. In particular, it is possible to use the avalanche protection helmet over a longer service life without the function of the carbon dioxide absorber being restricted. The avalanche safety helmet is particularly uncomplicated and thus inexpensive to produce.

Ein Schutzhelm nach Anspruch 2 ermöglicht einen verbesserten Schutz eines Skifahrers. Dadurch, dass der Schutzhelm als Integralhelm ausgeführt ist und einen Kinnschutz aufweist, begrenzt der Schutzhelm einen Innenraum, der in einer Unfallsituation als Atemreservoir dient.A protective helmet according to claim 2 allows improved protection of a skier. Due to the fact that the protective helmet is designed as a full-face helmet and has a chin guard, the protective helmet limits an interior which serves as a breathing reservoir in an accident situation.

Ein Schutzhelm nach Anspruch 3 weist eine verbesserte Absorption des Kohlendioxids auf. Der Kohlendioxid-Absorber ist an dem Kinnschutz befestigt, sodass Kohlendioxid der ausgeatmeten Luft direkt absorbiert werden kann.A protective helmet according to claim 3 has an improved absorption of carbon dioxide. The carbon dioxide absorber is attached to the chin guard so that carbon dioxide from the exhaled air can be directly absorbed.

Ein Schutzhelm nach Anspruch 4 ist besonders unkompliziert aufgebaut. Ein derartiger Schutzhelm unterscheidet sich äußerlich nicht von einem gewöhnlichen Integralhelm. Insbesondere erfüllt der Schutzhelm höchste ästhetische Ansprüche einerseits und ermöglicht die Absorption von Kohlendioxid andererseits. Insbesondere ist es möglich, den Kohlendioxid-Absorber an einer Innenseite des Schutzhelms anzuordnen, sodass der Kohlendioxid-Absorber von der Helmschale geschützt ist und insbesondere von außen nicht sichtbar ist.A protective helmet according to claim 4 is particularly uncomplicated. Such a protective helmet does not differ externally from a normal full-face helmet. In particular, the protective helmet meets the highest aesthetic demands on the one hand and allows the absorption of carbon dioxide on the other. In particular, it is possible to arrange the carbon dioxide absorber on an inner side of the protective helmet, so that the carbon dioxide absorber is protected by the helmet shell and in particular is not visible from the outside.

Ein Schutzhelm nach Anspruch 5 weist ein verbessertes Absorptionsverhalten auf. Ein Kohlendioxid-Absorber-Granulat ist beispielsweise von Narkosegeräten bekannt. Das Kohlendioxid-Absorber-Granulat kann sehr flexibel geformt und damit einer vorgegebenen Helmform angepasst werden.A protective helmet according to claim 5 has an improved absorption behavior. A carbon dioxide absorber granules is for example of Anesthesia equipment known. The carbon dioxide absorber granules can be shaped very flexible and thus adapted to a given helmet shape.

Ein Schutzhelm nach Anspruch 6 ermöglicht eine vorteilhafte Formgebung für das Kohlendioxid-Absorber-Granulat. Eine gasdurchlässige Umhüllung ermöglicht eine Absorption des Kohlendioxids durch das Granulat und eine flexible, definierte Formgebung des Granulats in der Umhüllung.A protective helmet according to claim 6 allows an advantageous shape for the carbon dioxide absorber granules. A gas-permeable enclosure allows absorption of the carbon dioxide by the granules and a flexible, defined shaping of the granules in the enclosure.

Ein Schutzhelm nach Anspruch 7 ermöglicht eine Konservierung des Kohlendioxid-Absorbers. Dadurch, dass der Kohlendioxid-Absorber in einer, insbesondere gasdichten, Hülle umschlossen ist, erfolgt eine Kohlendioxid-Absorption erst dann, wenn der Kohlendioxid-Absorber aktiviert worden ist. Der Kohlendioxid-Absorber kann über einen langen Zeitraum erhalten bleiben.A protective helmet according to claim 7 allows a preservation of the carbon dioxide absorber. Characterized in that the carbon dioxide absorber is enclosed in a, in particular gas-tight, shell, a carbon dioxide absorption takes place only when the carbon dioxide absorber has been activated. The carbon dioxide absorber can be retained over a long period of time.

Ein Schutzhelm nach Anspruch 8 ermöglicht eine unkomplizierte Aktivierung des Kohlendioxid-Absorbers.A protective helmet according to claim 8 enables uncomplicated activation of the carbon dioxide absorber.

Ein Schutzhelm nach Anspruch 9 ist unkompliziert herstellbar. Insbesondere ist es möglich, einen gewöhnlichen Schutzhelm mit einem daran befestigbaren Aufsatz zu kombinieren, wobei der Kohlendioxid-Absorber in den Aufsatz integriert ist. Eine unkomplizierte und insbesondere wieder lösbare Befestigung des Aufsatzes an dem Schutzhelm kann durch eine Klettverschluss-Verbindung, insbesondere durch mehrere Klettverschluss-Flächen, erfolgen. Dadurch ist es möglich, dass der den Kohlendioxid-Absorber enthaltende Aufsatz unabhängig von dem eigentlichen Schutzhelm hergestellt und anschließend an dem Schutzhelm befestigt wird. Es ist insbesondere auch möglich, einen beispielsweise beschädigten Aufsatz auszuwechseln oder nachzurüsten.A protective helmet according to claim 9 is easy to produce. In particular, it is possible to combine an ordinary protective helmet with an attachable thereto attachment, wherein the carbon dioxide absorber is integrated into the essay. An uncomplicated and in particular detachable attachment of the attachment to the protective helmet can be done by a Velcro connection, in particular by several Velcro surfaces. This makes it possible that the attachment containing the carbon dioxide absorber is produced independently of the actual protective helmet and then attached to the protective helmet. It is in particular also possible to replace or retrofit an example damaged attachment.

Ein Schutzhelm nach Anspruch 10 ermöglicht eine direkte und unkomplizierte Aktivierung des Kohlendioxid-Absorbers. Insbesondere ist es möglich, mindestens eine Aufreißschnur, die insbesondere aus Nylon hergestellt sein kann, vorzusehen. Die Aufreißschnur ist insbesondere derart an einer den Kohlendioxid-Absorber gasdicht umschließenden Hülle angebracht, dass ein Betätigen der Aufreißschnur ein Öffnen der Hülle bewirkt. Dadurch ist es einem Lawinen-Unfallopfer möglich, selbst in einer Unfallsituation den Kohlendioxid-Absorber zu aktivieren.A protective helmet according to claim 10 enables a direct and uncomplicated activation of the carbon dioxide absorber. In particular, it is possible to provide at least one tear-open cord, which may in particular be made of nylon. In particular, the tear-open cord is attached to a shell enclosing the carbon dioxide absorber in a gas-tight manner so that actuation of the tear-open cord causes the sheath to open. This makes it possible for an avalanche victim to activate the carbon dioxide absorber even in an accident situation.

Einander entsprechende Teile sind in den Fig. 1 bis 3 mit denselben Bezugszeichen versehen. Auch Einzelheiten des im Folgenden näher erläuterten Ausführungsbeispiels können für sich genommen eine Erfindung darstellen oder Teil eines Erfindungsgegenstandes sein.Corresponding parts are in the Fig. 1 to 3 provided with the same reference numerals. Also details of the embodiment explained in more detail below may constitute an invention per se or be part of an inventive subject matter.

In Fig. 1 bis 3 ist ein Lawinen-Schutzhelm 1 dargestellt. Der Lawinen-Schutzhelm 1 ist als Integralhelm mit einem Kinnschutz 2 insbesondere in Form eines Kinnbügels ausgeführt. Der Kinnschutz 2 bildet einen umlaufenden, unteren Rand des Lawinen-Schutzhelms 1. Von dem Lawinen-Schutzhelm 1 ist ein Innenraum 3 umschlossen, der zur Aufnahme des Kopfes eines Helmträgers dient. Der Kinnschutz 2 ist derart gestaltet, dass ein Abstand zwischen einer Innenseite 4 des Lawinen-Schutzhelms 1 und dem Kinn des Helmträgers vorgesehen ist. Dieser Abstandsbereich dient als Reservoir für Atemluft in einer Unfallsituation, insbesondere durch Lawinenverschüttung. An der Innenseite 4 ist ein Aufsatz 5 vorgesehen, der mittels einer Klettverschluss-Verbindung an der Innenseite 4 des Lawinen-Schutzhelms 1 befestigt ist. Die Klettverschluss-Verbindung umfasst mehrere kreisförmige Klettverschluss-Flächen 6, wobei beispielsweise an der Innenseite 4 eine Klettverschluss-Fläche 6 mit Widerhaken und an dem Aufsatz 5 eine dazu korrespondierende Klettverschluss-Fläche 6 mit Schlaufen vorgesehen ist. Es ist auch möglich, die Klettverschluss-Flächen 6 an der Innenseite 4 und dem Aufsatz 5 wechselseitig anzubringen. Es ist auch möglich, dass die Klettverschluss-Flächen 6 eine unrunde Kontur aufweisen. Die einzelnen Klettverschluss-Flächen 6 ermöglichen eine sichere und gleichzeitig schnelle und wieder lösbare Befestigung des Aufsatzes 5 an dem Lawinen-Schutzhelm. Aufgrund der lösbaren Befestigung des Aufsatzes 5 an dem Lawinen-Schutzhelm 1 ist ein Austausch und/oder ein Nachrüsten des Kohlendioxid-Absorbers 7 an dem Lawinen-Schutzhelm 1 ermöglicht bzw. vereinfacht.In Fig. 1 to 3 An avalanche protection helmet 1 is shown. The avalanche protective helmet 1 is designed as a full-face helmet with a chin guard 2, in particular in the form of a chin strap. The chin guard 2 forms a circumferential, lower edge of the avalanche protection helmet 1. The avalanche protection helmet 1 encloses an interior 3, which serves to receive the head of a helmet wearer. The chin guard 2 is designed such that a distance between an inside 4 of the avalanche protection helmet 1 and the chin of the helmet wearer is provided. This distance range serves as a reservoir for breathing air in an accident situation, in particular by avalanche burial. On the inside 4 an attachment 5 is provided, which is fastened by means of a Velcro connection on the inside 4 of the avalanche protection helmet 1. The hook-and-loop fastener connection comprises a plurality of circular hook-and-loop fastener surfaces 6, wherein, for example, a hook-and-loop fastener surface 6 with barbs is provided on the inside 4 and a hook-and-loop fastener surface 6 with loops corresponding thereto is provided on the attachment 5. It is also possible to attach the Velcro surfaces 6 on the inside 4 and the top 5 alternately. It is also possible that the Velcro surfaces 6 have a non-circular contour. The individual Velcro surfaces 6 allow a secure and at the same time quick and detachable attachment of the attachment 5 to the avalanche protection helmet. Due to the detachable attachment of the attachment 5 to the avalanche protection helmet 1, an exchange and / or retrofitting of the carbon dioxide absorber 7 on the avalanche protection helmet 1 is made possible or simplified.

Es ist auch denkbar, den Aufsatz 5 in einer anderen Weise an dem Lawinen-Schutzhelm 1 zu befestigen. Beispielsweise könnte dies mittels eines umlaufenden Reißverschlusses oder mittels Druckknöpfen erfolgen.It is also conceivable to attach the attachment 5 in a different manner to the avalanche protection helmet 1. For example, this could be done by means of a circumferential zipper or snaps.

In dem Aufsatz 5 ist ein Kohlendioxid-Absorber 7 integriert. Der Kohlendioxid-Absorber 7 umfasst ein Kohlendioxid-Absorber-Granulat 8, das von einer gasdurchlässigen Umhüllung in Form eines Textilbeutels 9 umschlossen ist. Der Textilbeutel 9 ermöglicht eine vorteilhafte Formgebung des Kohlendioxid-Absorber-Granulats 8 zu dem Kohlendioxid-Absorber 7. Der Kohlendioxid-Absorber 7 kann besonders vorteilhaft an die Innenform des Lawinen-Schutzhelms 1 angebracht werden. Der Kohlendioxid-Absorber 7 ist unauffällig in den Lawinen-Schutzhelm 1 integriert. Gemäß dem gezeigten Ausführungsbeispiel weist der Kohlendioxid-Absorber 7 eine Dicke D von etwa 1 cm auf. Die Dicke D ist im Wesentlichen senkrecht zu der Innenseite 4 des Lawinen-Schutzhelms 1 orientiert. Der Textilbeutel 9 ist luftdurchlässig und ermöglicht dadurch, dass Kohlendioxid durch den Textilbeutel 9 zu dem darin angeordneten Kohlendioxid-Absorber-Granulat 8 gelangen und dort absorbiert werden kann.In the article 5, a carbon dioxide absorber 7 is integrated. The carbon dioxide absorber 7 comprises a carbon dioxide absorber granulate 8, which is enclosed by a gas-permeable envelope in the form of a textile bag 9. The textile bag 9 allows an advantageous shaping of the carbon dioxide absorber granules 8 to the carbon dioxide absorber 7. The carbon dioxide absorber 7 can be particularly advantageously attached to the inner shape of the avalanche protective helmet 1. The carbon dioxide absorber 7 is inconspicuously integrated into the avalanche protective helmet 1. According to the embodiment shown, the carbon dioxide absorber 7 has a thickness D of about 1 cm. The thickness D is oriented substantially perpendicular to the inside 4 of the avalanche protection helmet 1. The textile bag 9 is permeable to air and thereby allows carbon dioxide to pass through the textile bag 9 to the carbon dioxide absorber granules 8 arranged therein and can be absorbed there.

Der Textilbeutel 9 ist von einer Kunststoff-Hülle 10 gasdicht umschlossen. Dadurch ist gewährleistet, dass, solange die Kunststoff-Hülle 10 unversehrt ist, das darin angeordnete Kohlendioxid-Absorber-Granulat 8 nicht aktiviert ist. Das bedeutet, das Kohlendioxid-Absorber-Granulat 8 absorbiert kein Kohlendioxid, solange die Kunststoff-Hülle 10 verschlossen ist. Dadurch ist gewährleistet, dass der Kohlendioxid-Absorber 7 unverbraucht und frisch ist, solange keine Aktivierung des Kohlendioxid-Absorbers 7 erfolgt.The textile bag 9 is enclosed by a plastic sleeve 10 gas-tight. This ensures that, as long as the plastic shell 10 is intact, the disposed therein carbon dioxide absorber granules 8 is not activated. That is, the carbon dioxide absorber granules 8 are absorbed no carbon dioxide, as long as the plastic sheath 10 is closed. This ensures that the carbon dioxide absorber 7 is fresh and fresh, as long as no activation of the carbon dioxide absorber 7 takes place.

Eine Aktivierung des Kohlendioxid-Absorbers 7 ist mittels eines Aktivieningselements in Form einer Aufreißschnur 11, beispielsweise aus Nylon, möglich. Die Aufreißschnur 11 ist in den Aufsatz 5 derart integriert und an der Kunststoff-Hülle 10 befestigt, dass ein Betätigen der Aufreißschnur 11 zu einem Aufreißen der Kunststoff-Hülle 10 führt.Activation of the carbon dioxide absorber 7 is possible by means of an active-ring element in the form of a tear-open cord 11, for example of nylon. The tear-open cord 11 is integrated into the attachment 5 and attached to the plastic sleeve 10 such that actuation of the tear-open cord 11 leads to tearing of the plastic sleeve 10.

Die Aufreißschnur 11 ist mit einem freien Ende an dem Aufsatz 5 weggeführt und weist einen Ring 12 auf. Der Ring 12 ermöglicht ein vorteilhaftes Greifen und Betätigen der Aufreißschnur 11. Die Aufreißschnur 11 ist umlaufend entlang des Kinnschutzes 2 in den Aufsatz 5 integriert. Es ist insbesondere denkbar, die Aufreißschnur 11 derart in den Aufsatz 5 zu integrieren, dass die Aufreißschnur 11 eine Kontur bildet. In diesem Fall wird durch Betätigung der Aufreißschnur 11 der Textilbeutel 9 großflächig freigelegt und somit die Aktivierung des Kohlendioxid-Absorbers verbessert.The tear-open cord 11 is led away with a free end on the attachment 5 and has a ring 12. The ring 12 allows an advantageous gripping and operating the tear-open 11. The tear-11 is integrated circumferentially along the chin guard 2 in the article 5. In particular, it is conceivable to integrate the tear-open cord 11 into the attachment 5 such that the tear-open cord 11 forms a contour. In this case, the textile bag 9 is exposed over a large area by actuation of the tear-open cord 11, thus improving the activation of the carbon dioxide absorber.

Der Kohlendioxid-Absorber wird aktiviert, indem der Textilbeutel 9 mit dem darin angeordneten Kohlendioxid-Absorber-Granulat 8 mit dem Atemluftreservoir in dem Innenraum 3 des Lawinen-Schutzhelms 1 verbunden wird. Dadurch kann Kohlendioxid aus der Atemluft von dem Kohlendioxid-Absorber-Granulat 8 des Kohlendioxid-Absorbers 7 absorbiert werden. Die in dem Atemluftreservoir angeordnete Luft kann in einer Unfallsituation mehrfach geatmet werden. Dadurch kann ein Unfallopfer längere Zeit in einer verschütteten Situation atmen und bleibt dadurch für einen längeren Zeitraum überlebensfähig.The carbon dioxide absorber is activated by connecting the textile bag 9 with the carbon dioxide absorber granules 8 arranged therein to the respiratory air reservoir in the interior 3 of the avalanche protection helmet 1. As a result, carbon dioxide from the breathing air can be absorbed by the carbon dioxide absorber granules 8 of the carbon dioxide absorber 7. The air arranged in the breathing air reservoir can be breathed several times in an accident situation.
