Abstract
Description
Die Erfindung betrifft eine gefaltete Schutzhaube mit einem Sichtfenster und einer Sauerstoffmaske, die mit einem Atemgasanschluß zur Sauerstoffversorgung versehen ist.The invention relates to a folded protective hood with a viewing window and an oxygen mask, which is provided with a breathing gas connection for oxygen supply.
Derartige Schutzhauben werden beispielsweise für Passagiere in Flugzeugen benutzt, um ihnen im Notfall geeigneten Schutz vor einer Rauchentwicklung und eine notwendige Versorgung von Sauerstoff im Falle einer Dekompression zu ermöglichen. Eine solche kombinierte Schutzhaube ist in der US-A-4 559 939 beschrieben worden.Protective hoods of this type are used, for example, for passengers in aircraft in order to provide them with suitable protection against smoke in an emergency and a necessary supply of oxygen in the event of decompression. Such a combined protective hood has been described in US-A-4,559,939.
Die Handhabung derartiger kombinierter Schutzhauben ist jedoch insofern aufwendig, als zunächst die Schutzhaube über den Kopf gezogen werden muß, bevor der Atemanschluß zur Sauerstoffversorgung hergestellt werden kann. Dieser Handhabungsvorgang verlängert unnötigerweise die Zeit, bis zu der die Sauerstoffversorgung im Dekompressionsfalle tatsächlich dem Passagier zunutze kommt. Im Dekompressionsfalle ist zunächst vorrangig, die erforderliche Sauerstoffversorgung sicherzustellen. Dies kann man bei der bekannten Schutzhaube dadurch erreichen, daß zunächst nur die Maske gegen das Gesicht gedrückt wird. Kommt es im Verlaufe des Notfalles zu einer belästigenden oder gefährdenden Rauchentwicklung, die das Anlegen einer Rauchschutzhaube erfordert, muß die vorher angelegte Sauerstoffmaske abgesetzt, die Schutzhaube über den Kopf gezogen und die Atemgasversorgung durch Aufsetzen der Sauerstoffmaske auf einen entsprechenden, an der Schutzhaube vorgesehenen Anschluß wiederhergestellt werden. Während der Durchführung dieser Handlungen ist der Passagier von der Sauerstoffversorgung abgekoppelt und muß die Haube umständlich entfalten und über seinen Kopf ziehen. Für diese Arbeiten kann man im Notfall aber nicht die genügende Zeit und Sorgfalt aufwenden, so daß es zu Mißgriffen und unkorrektem Sitzen der Haube kommen kann.However, the handling of such combined protective hoods is complex in that the protective hood must first be pulled over the head before the breathing connection for oxygen supply can be established. This handling process unnecessarily extends the time until the oxygen supply in the decompression case actually benefits the passenger. In the event of decompression, the first priority is to ensure the necessary oxygen supply. This can be achieved with the known protective hood by initially pressing only the mask against the face. If, in the course of an emergency, there is a nuisance or danger in the development of smoke, which requires the installation of a smoke protection hood, the previously created one must Oxygen mask removed, the protective hood pulled over the head and the respiratory gas supply can be restored by putting the oxygen mask on an appropriate connection provided on the protective hood. During the execution of these actions, the passenger is disconnected from the oxygen supply and has to unfold the hood and pull it over his head. In an emergency, however, it is not possible to spend sufficient time and care for this work, so that the hood can be misplaced and incorrectly seated.
Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, eine Schutzhaube der genannten Art so zu verbessern, daß zunächst die Sauerstoffversorgung ungehindert sichergestellt sein kann und im Bedarfsfalle die Schutzhaube mit einem sicheren Handgriff über den Kopf gezogen werden kann, ohne daß dabei die Sauerstoffversorgung unterbrochen zu werden braucht.The present invention is therefore based on the object of improving a protective hood of the type mentioned so that initially the oxygen supply can be ensured unimpeded and, if necessary, the protective hood can be pulled over the head with a secure handle without interrupting the oxygen supply needs.
Die Lösung der Aufgabe erfolgt mit den im kennzeichnenden Teil des Anspruchs 1 dargestellten Merkmalen.The problem is solved with the features shown in the characterizing part of claim 1.
Der Vorteil der Erfindung liegt im wesentlichen darin, daß die Schutzhaube im gefalteten Zustand die freie Innenfläche der Sauerstoffmaske dem Passagier zuwendet, so daß dieser im Dekompressionsfalle sofort die Maske anlegen kann und mit Sauerstoff versorgt wird. Wird es während dieser Zeit notwendig, die Schutzhaube über den Kopf zu ziehen, braucht der Passagier lediglich mit der einen Hand an dem Griffrand zu ziehen, so daß sich die nach außen gefaltete Innenfläche der Schutzhaube in Folge der Zugwirkung selbsttätig entfaltet und mit einem Zuggriff über den Kopf hinweg bis zum Nacken sicher angelegt werden kann. Während dieser Zeit kann die Sauerstoffmaske mit der anderen Hand ständig an Mund und Nasenbereich angedrückt bleiben, da das Überziehen der Schutzhaube mit nur einer Hand möglich wird.The advantage of the invention lies essentially in the fact that the protective hood, when folded, turns the free inner surface of the oxygen mask towards the passenger, so that in the event of decompression he can immediately put on the mask and is supplied with oxygen. If it becomes necessary during this time to pull the protective hood over the head, the passenger need only pull on the edge of the handle with one hand, so that the inner surface of the protective hood folded outwards unfolds automatically as a result of the pulling action and with one Access can be securely applied over the head to the neck. During this time, the oxygen mask can be kept pressed on the mouth and nose area with the other hand, since the protective hood can be pulled over with only one hand.
Die gefaltete Schutzhaube benötigt nur wenig mehr Platz als die Sauerstoffmaske selbst und behindert die Handhabung der Sauerstoffmaske während der Atmung im Dekompressionsfalle nicht. Die Packung der Haube ist klein und benötigt somit wenig Stauplatz.The folded protective hood requires only a little more space than the oxygen mask itself and does not hinder the handling of the oxygen mask during breathing in the event of decompression. The pack of the hood is small and therefore requires little storage space.
Besonders vorteilhaft erweist es sich, sowohl die Halteelemente als auch den Griffrand als Klettbandverschlüsse auszubilden, welche sich beim Überziehen der Kopfhaube von selbst lösen und die gewickelten Enden der Schutzhaube freigeben.It proves to be particularly advantageous to design both the holding elements and the grip edge as Velcro fasteners, which release themselves when the hood is pulled over and release the wound ends of the protective hood.
Zweckmäßigerweise ist der Griffrand aus einer Halteschlaufe gebildet, er kann aber auch als eine Durchgriffsöffnung am Rande der Haubenöffnung im Nackenbereich ausgebildet sein.The edge of the handle is expediently formed from a holding loop, but it can also be designed as a passage opening at the edge of the hood opening in the neck area.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung dargestellt und im folgenden näher erläutert.An embodiment of the invention is illustrated by the drawing and explained in more detail below.

- Figure 1
- The folding conditions af from the spread out to the packed protective cover
- Figure 2
- The folded protective hood seen from the mask side.
Die in Figur 1, Teil a, gezeichnete Schutzhaube (1) ist im ausgebreiteten Zustand gezeichnet und zeigt einen Kopfbereich (2) mit einem Sichtfenster (3), unter welchem ein Atemgasanschluß (4) mit einem Ausatemventil (5) für die dahinterliegende Sauerstoffmaske versehen ist. Der Haubenrand (7) schließt den unterhalb des Sichtfensters befindlichen Halsbereich (8) der Haube (1) ab. Ein Atembeutel (9) ist an den Atemgasanschluß (4) befestigt und über ein Schlauchstück (10) mit einer nicht dargestellten Sauerstoffquelle verbindbar. Die in Teilfigur a dargestellte Haube (1) wird zunächst längst der Pfeile A von hinten nach vorne aufgerollt, bis der am rückwärtigen Teil des Haubenrandes (7) angebrachte Griffrand in Form einer Schlaufe (11) hervortritt (siehe Teilfigur b). Anschließend wird das vorderseitige Teilstück des Haubenrandes (7) ebenfalls von hinten nach vorne in Bewegungsrichtung der Pfeile B in Richtung des Anschlußstückes (4) aufgerollt. Die in Teilfigur c dargestellte obere Rolle (12) und untere Rolle (13) liegen in vertikaler Richtung beidseitig des Anschlußstückes (4) und des Ausatemventils (5). Längs der Richtungspfeile C wird die Schlaufe (11) in Richtung auf das Anschlußstück (4) umgefaltet und die beiden Verbindungsseiten (15) zwischen den Enden beider Rollen (12, 13) in Richtung der Pfeile D ebenfalls zum Anschlußstück (4) hin umgelegt. Danach sind, wie in Teilfigur e ersichtlich, auf der Innenseite angebrachte Halteelemente (14) in Form von Klettbändern sichtbar, die mit den entsprechenden Klettbändern (14) der hochgeschlagenen Schlaufe (11) verheftet werden (Richtungspfeile E). Die fertig gefaltete Schutzhaube nach Teilfigur f ist somit von allen vier Richtungen zu dem Anschlußstück (4) und dem Ausatemventil (5) hin zusammengewickelt und wird durch die Schlaufe (11) zusammengehalten. Sie zeigt auf der Rückseite gemäß Figur 2 den nicht gefalteten Teil der Innenwand (16) der Haube (1) in dem freiliegenden Teilbereich um die Sauerstoffmaske (6), deren Dichtrand (17) die zum Benutzer weisenden Einlaßöffnungen des Atemgasanschlusses (4) und des Ausatemventils (5) umschließt.The protective hood (1) shown in FIG. 1, part a, is drawn in the expanded state and shows a head region (2) with a viewing window (3), under which a breathing gas connection (4) is provided with an exhalation valve (5) for the oxygen mask behind it is. The hood edge (7) closes off the neck area (8) of the hood (1) located below the viewing window. A breathing bag (9) is attached to the breathing gas connection (4) and can be connected to an oxygen source (not shown) via a piece of hose (10). The hood (1) shown in part figure a is first rolled up along the arrows A from the back to the front until the grip edge attached to the rear part of the hood edge (7) emerges in the form of a loop (11) (see part figure b). Then the front section of the hood edge (7) is also rolled up from the back to the front in the direction of the arrows B in the direction of the connector (4). The upper roller (12) and lower roller (13) shown in partial figure c are located in the vertical direction on both sides of the connecting piece (4) and the exhalation valve (5). The loop (11) is folded over in the direction of the arrows C in the direction of the connector (4) and the two connecting sides (15) between the ends of both rollers (12, 13) are also folded in the direction of the arrows D towards the connector (4). Thereafter, as can be seen in partial figure e, attached holding elements (14) in the form of Velcro strips are visible on the inside, which are stitched with the corresponding Velcro strips (14) of the loop (11) folded up (directional arrows E). The fully folded protective hood according to sub-figure f is thus wound together from all four directions to the connecting piece (4) and the exhalation valve (5) and is held together by the loop (11). It shows on the back of Figure 2 the unfolded part of the inner wall (16) of the hood (1) in the exposed area around the oxygen mask (6), the sealing edge (17) of the user-facing inlet openings of the breathing gas connection (4) and Exhales valve (5) encloses.
