Description

Die Erfindung betrifft eine Passagiersauerstoffmaske mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to a passenger oxygen mask with the in the preamble of claim 1 specified characteristics.

Passagiersauerstoffmasken sind an Bord von Flugzeugen vorgesehen, um die Passagiere in Notfallsituationen und in der Phase eines Post-Dekompressions-Flughöhenabstiegs des Flugzeugs mit Sauerstoff zu versorgen sowie Passagieren, die während des normalen Flugbetriebs zusätzlichen Sauerstoff benötigen, therapeutischen Sauerstoff zur Verfügung zu stellen.Passenger oxygen masks are provided on board aircraft around the passengers in emergency situations and in the phase of post-decompression flight altitude descent to supply the aircraft with oxygen and passengers who are extra during normal flight operations Need oxygen, therapeutic oxygen available to deliver.

Bekannte Passagiersauerstoffmasken weisen üblicherweise einen rotationssymmetrischen Maskenkörper auf, dessen kreisrunde Atemöffnung der Passagier im Anwendungsfall an den Gesichtsbereich rund um Nase und Mund anlegt. Wegen des kreisrunden Öffnungsquerschnitts des Maskenkörpers liegt die Passagiersauerstoffmaske nicht immer vollständig an dem Gesicht des Benutzers an, so dass ein Zwischenraum zwischen Gesicht und Maskenkörper offen und damit luftdurchlässig bleibt. Je nach Gesichtsphysiognomie fallen diese Zwischenräume mehr oder weniger groß aus. Durch diese Spalte geht bei Sauerstoffmasken, die einen konstanten Sauerstoffstrom zur Verfügung stellen, eine nicht unerheblich große Menge Sauerstoff verloren. Sauerstoffmasken, bei denen die Sauerstoffzufuhr nur dann erfolgt, wenn ein in dem Maskenkörper angeordnetes Ventil durch den Einatemimpuls geöffnet wird, können von dem Benutzer nur schwer bzw. gar nicht aktiviert werden, da der zum Öffnen des Ventils erforderliche Unterdruck in dem Maskenkörper aufgrund der Zwischenräume zwischen Maskenkörper und Gesicht nicht aufgebaut werden kann. Dies kann bei Passagieren zu einer Hypoxie führen.Known passenger oxygen masks usually have a rotationally symmetrical Mask body on, whose circular breathing opening the passenger in the application to the facial area around nose and mouths. Because of the circular opening cross section of the Mask body, the passenger oxygen mask is not always complete on the user's face, leaving a gap between Face and mask body remains open and thus permeable to air. Depending on the physiognomy of the face, these spaces are more or less less big. Through this column goes with oxygen masks, the provide a constant flow of oxygen, not insignificant lost a lot of oxygen. Oxygen masks in which the oxygen supply takes place only if one in the mask body arranged valve is opened by the inspiration pulse can be difficult or not activated by the user because of the required to open the valve vacuum in the mask body due to the gaps between mask body and face can not be established. This can cause hypoxia in passengers to lead.

Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Passagiersauerstoffmaske zu schaffen, welche dem Benutzer sicher und in ausreichendem Maße Sauerstoff zu Verfügung stellt und dabei einfach und kostengünstig hergestellt werden kann.Against this background, the present invention has the object underlying to create a passenger oxygen mask, which the user safely and to a sufficient extent provides oxygen and can be easily and inexpensively manufactured.

Diese Aufgabe wird erfindungsgemäß durch eine Passagiersauerstoffmaske mit den im Anspruch 1 angegebenen Merkmalen gelöst.

At least one Section of the mask body is plastically deformable or provided for receiving a plastically deformable support element.

Der weichelastische Maskenkörper ist bevorzugt rotationssymmetrisch und mit einer kreisrunden Atemöffnung ausgebildet. Dies ist insbesondere für die Betriebssicherheit der Passagiersauerstoffmaske erforderlich, da die Sauerstoffmasken so, beispielsweise in Paniksituationen, in allen Positionen in Achslage aufgesetzt und eingesetzt werden können. Nach einer Beruhigung des Passagiers kann die Sauerstoffmaske gegebenenfalls richtig positioniert werden. Anschließend ist es möglich, den plastischen Abschnitt des Maskenkörpers zu verformen und so den Öffnungsbereich des Maskenkörpers an die Gesichtskontur anzupassen, wodurch der offene Zwischenraum zwischen dem Maskenkörper und dem Gesicht minimiert bzw. geschlossen wird.The soft-elastic mask body is preferably rotationally symmetrical and formed with a circular breathing opening. This is special necessary for the operational safety of the passenger oxygen mask, because the oxygen masks so, for example in panic situations, in all Positions can be placed in axis position and used. To a reassurance of the passenger, the oxygen mask, if necessary be positioned correctly. Then it is possible to do the plastic Section of the mask body to deform and so the opening area of the mask body to match the facial contour, whereby the open space between the mask body and the face is minimized or closed.

Bevorzugt ist der Maskenkörper im Bereich der Anlagefläche zur Nase des Benutzers plastisch verformbar ausgebildet, da der Maskenkörper in diesem Bereich aufgrund der Topographie des Gesichts von der übrigen Gesichtsoberfläche besonders beabstandet ist.Preferably, the mask body is in the region of the contact surface to the nose the user formed plastically deformable, since the mask body in this area due to the topography of the face of the rest Facial surface is particularly spaced.

Es kann auch vorteilhaft sein, den Maskenkörper vollständig flexibel zu gestalten und auf dem Maskenkörper im Bereich der Nase ein Stützelement aufzusetzen, welches so verformbar ist, dass es die Atemöffnung des Maskenkörpers möglichst lückenlos an die Gesichtsoberfläche zwingt.It may also be advantageous to fully flexible the mask body shape and on the mask body in the nose area a support element to sit up, which is so deformable that it is the respiratory opening the mask body as completely as possible to the face surface forces.

Eine Drahtstruktur ermöglicht beispielsweise eine besonders gewichtssparende Ausführungsform des Stützelements, wodurch der Tragekomfort der Sauerstoffmaske verbessert werden kann. Als Material für das Stützelement können alle Metalle eingesetzt werden, die gewährleisten, dass das Stützelement ohne besondere Kraftanstrengung plastisch verformt werden kann.If the mask body is deformed by the reception of a support element, this support element is preferably made of a metallic material educated. The support element is advantageously made of a thin, easily bendable sheet or made of a wire structure, wherein the Dimensions of the sheet or the wire structure of the size of the deformed Mask section are adjusted and a slight deformation enable the support element. A wire structure, for example, allows a particularly weight-saving embodiment of the Support element, which improves the comfort of the oxygen mask can be. As material for the support element, all metals be used, which ensure that the support element without special Strain can be plastically deformed.
