Abstract

1. Respiratory half-mask for once-only use, in a form which ensures a fit over the nose, cheeks and chin of a user, and having, as a headband, (2) an endless resilient band, characterised in that the headband (2) passes through a loose sleeve fixed, one opposite each cheek, on the outside near a sealing edge (4) on a body of the half-mask (1) and is divided into a lower length (5) and an upper length (6).

Description

Die Erfindung betrifft eine Atemhalbmaske für den Einmalgebrauch, entsprechend dem Gattungsbegriff des Anspruchs 1.The invention relates to a breathing half mask for single use, according to the preamble of claim 1.

Atemhalbmasken für den Einmalgebrauch verlangen eine einfache Handhabung beim Anlegen. Eine wesentliche Voraussetzung dazu ist die Anpassung der Kopfbänderung.Breathing half masks for single use require easy handling when putting on. An essential requirement for this is the adjustment of the head harness.

Eine bekannte Atemhalbmaske für den Einmalgebrauch aus einem Filtermaterial in einer Form, die einen Sitz über der Nase, den Wangen und dem Kinn des Benutzers mit einem genügend freien Raum um diesen herum sichert, besitzt Kopfbänder, die durch endlose Elastikbänder dargestellt sind. Sie sind in Seitenschlitzen von Laschen eingehängt, die wiederum Teile des Verstärkungsrahmens am Rande des Maskenkörpers sind. Schwierigkeiten ergeben sich hier aus dem notwendigen Einhängen des Kopfbandes in die Seitenschlitze und dem möglichen Ausfädeln während des Anlegens. Der für einen guten Sitz mit gleichmäßigem Zug der Kopfbänder notwendige Ausgleich der Bandlängen wird durch den Zug in die Seitenschlitze hinein behindert. (DE-OS 29 38 720) Aufgabe der Erfindung ist eine Kopfbänderanbringung an den Maskenkörper der Atemhalbmaske, die das Anlegen einfach macht und einen dichten Sitz ohne besondere Anpassungsmühen sichert.A well-known single-use respiratory half mask made of a filter material in a form that secures a seat over the nose, cheeks and chin of the user with a sufficient free space around it has headbands which are represented by endless elastic bands. They are hung in the side slots of tabs, which in turn are part of the reinforcement frame on the edge of the mask body. Difficulties arise here from the necessary hanging of the headgear into the side slits and the possible unthreading during application. The adjustment of the strap lengths necessary for a good fit with even pulling of the head straps is hindered by the pull into the side slots. (DE-OS 29 38 720) The object of the invention is a headgear attachment to the mask body of the respiratory half mask, which makes it easy to put on and ensures a tight fit without any special adjustment effort.

Die Lösung erfolgt gemäß dem Kennzeichen der Patentansprüche. Sie ist sehr vorteilhaft. Das Aufsetzen der Halbmaske wird dadurch erleichtert, daß fast die Gesamtlänge des Kopfbandes zum Überstreifen über den Kopf zur Verfügung steht. Die Unterlänge umfaßt dabei durch das Hindurchziehen des Kopfbandes durch die Ösen praktisch die gesamte Kopfbandlänge. Beim Nichtgebrauch kann die Atemhalbmaske vor der Brust getragen werden. Die Spannkräfte an der Ober-und Unterlänge gleichen sich über den Längenausgleich, angenaßt durch die Ösen, aus.The solution is according to the characterizing part of the claims. It is very beneficial. Putting on the half mask is made easier by the fact that almost the entire length of the headgear is available for slipping over the head. By pulling the headband through the eyelets, the descender practically covers the entire headband length. The breathing mask can be worn in front of the chest when not in use. The clamping forces on the upper and lower lengths are balanced out by the length compensation, adjusted by the eyelets.

An exemplary embodiment of the invention is shown in the drawing. Show it
  • 1 the overall view,
  • Fig. 2 shows the individual representation of an eyelet.

ber Halbmaskenkörper 1 deckt in bekannter Weise die Nase und den Mund ab. Die Dichtungslinie verläuft dabei über der Nase, den Wangen und dem Kinn des Trägers. Das Kopfband 2 in endloser Ausführung, wie z.B. von den Coupon-Gummibändern her bekannt, ist lose in je einer Öse 3,gegenüber den Wangen, geführt. Die Ösen 3 bestehen z.B. aus einem Kunststoffmaterial und sind von außen in der Nähe des Dichtungsrandes 4 durch Klebung oder Schweißung befestigt. Die Ösen zur Führung des Kopfbandes können auch aus dem Halbmaskenkörper überstehende, umgeschlagene Laschen 7 sein, die durch z.B. Schweißung oder Klebung befestigt 8 sind. Die Unterlänge 5 des Kopfbandes legt sich nach dem Aufsetzen der Halbmaske 1 um die Nackenpartie und die Oberlänge 6 um die Kopfpartie herum.About half-mask body 1 covers the nose and mouth in a known manner. The sealing line runs over the nose, cheeks and chin of the wearer. The headband 2 in an endless design, as is known, for example, from the coupon rubber bands, is loosely guided in an eyelet 3 opposite the cheeks. The eyelets 3 consist, for example, of a plastic material and are from the outside in the vicinity of the sealing edge 4 fixed by gluing or welding. The eyelets for guiding the headband can also be folded-over tabs 7 which protrude from the half-mask body and which are fastened 8 by, for example, welding or gluing. The lower length 5 of the headband wraps around the neck area after the half mask 1 has been put on and the upper length 6 around the head area.
