Description

Gasschutzmaske oder -haube Bei den bekannten, meist aus imprägniertem Gewebe hergestellten Gasschutzmasken oder -hauben läßt die Dichtigkeit mit der Zeit nach; bei Verwendung von gummiertem Gewebe z. B. wird der Gummi nach einiger Zeit brüchig, so daß die Maske dann denAtmungsorganen keinen zuverlässigen Schutz mehr bietet.Gas protective mask or hood With the known, mostly made of impregnated Fabric-made gas protective masks or hoods leaves the tightness over time after; when using rubberized fabric z. B. the rubber becomes after some time brittle, so that the mask then no longer provides reliable protection for the respiratory organs offers.

Es wurde nun gefunden, daß es möglich ist, Gasschutzmasken oder -hauben aus Metall herzustellen, deren Gasundurchlässigkeit bedeutend zuverlässiger ist als die der bisher bekannten Gasschutzmasken oder -hauben. Bei Metall besteht keinerlei Gefahr des Alterns und Austrocknens. Zur Herstellung derartiger Gasschutzmasken oder -hauben werden erfindungsgemäß dünn gewalzte Metallfolien verwendet, welche mittels Klebstoff ein- oder beiderseitig mit anderen, den mechanischen Widerstand erhöhenden Materialien vegbunden werden. Hierzu eignen sich vorzugsweise faserfreie Cellülosehäute.It has now been found that it is possible to use protective gas masks or hoods made of metal, the gas impermeability of which is significantly more reliable than those of the previously known gas protective masks or hoods. In the case of metal, there is nothing Risk of aging and dehydration. For the production of such gas protective masks or hoods, thinly rolled metal foils are used according to the invention, which by means of adhesive on one or both sides with others, the mechanical resistance increasing materials. Fiber-free are preferably suitable for this purpose Cellulose skins.

Aus diesem kombinierten Baustoff he= stehende Gasschutzmasken sind gegen mechanische Beschädigungen sehr widerstandsfähig, insbesondere dann, wenn die Metallfolie zwischen zwei faserfreien 'Häuten eingebettet ist und so von beiden Seiten vor Beschädigungen bewahrt wird.He = standing gas protective masks are made of this combined building material very resistant to mechanical damage, especially when the metal foil is embedded between two fiber-free 'skins and so from both Pages is protected from damage.

Der in dieser Weise zusammengesetzte gasundurchlässige Baustoff der Maske oder Haube kann- ferner in bei Gasschutzmasken andererArt bekannter Weise ein- oder beiderseitig mit einer Gewebeschicht überzogen werden, welche jedoch nicht zur Erhöhung der Gasundurchlässigkeit beizutragen hat, sondern lediglich zum Schutze der gasundurchlässigen Schicht dient.The gas-impermeable building material of the assembled in this way Mask or hood can also be used in a manner known from other types of gas protective masks be coated on one or both sides with a layer of fabric, which, however, are not has to contribute to increasing the gas impermeability, but only to the protection the gas-impermeable layer is used.
