Den Gegenstand der Erfindung bildet eine Verbesserung an Atmungshelmen.The subject of the invention is an improvement in respiratory helmets.

Die Verbesserung besteht darin, daß das oberhalb des Gesichts angeordnete Mundstück der Außenluftleitung sich düsenartig verengt, wobei die Düsenöffnung zweckmäßig die Gestalt eines der Gesichtsform entsprechend gekrümmten Schlitzes besitzt.The improvement is that the mouthpiece is located above the face the outside air line narrows like a nozzle, the nozzle opening expediently having the shape has a slot that is curved to match the shape of the face.

Die düsenartige Verengung des Mundstücks bezweckt und bewirkt eine festere Führung des Außenluftstromes. Letzterer nimmt nach Verlassen des Mundstücks die Form eines breiten Streifens an, welcher das Gesicht des Trägers gänzlich einhüllt. Dadurch wird die Verwendung besonderer Gesichtsmasken entbehrlich gemacht.The nozzle-like narrowing of the mouthpiece aims and causes a firmer guidance of the outside air flow. The latter takes the form of a after leaving the mouthpiece wide strip, which completely envelops the wearer's face. This will make the Use of special face masks made dispensable.

Beiliegende Zeichnung stellt eine Ausführungsform der Erfindung dar:The accompanying drawing shows an embodiment of the invention:

Fig. ι ist eine Vorderansicht,
Fig. 2 ein Schnitt nach Linie A-B von Fig- -i,.
Fig. Ι is a front view,
Fig. 2 is a section along line AB of Fig- -i ,.

Fig. 3 eine Seitenansicht.Fig. 3 is a side view.

Es bezeichnet:It denotes:

α den Helm oder die sonstige Kopfbedeckung, b den über das Gesicht vorspringenden Schirm derselben, c ist die Luftleitung, an deren eines Ende d sich eine Schlauchleitung anschließt, während das andere Ende e den Schirm durchdringt, so daß,, wenn die Drosselklappe f geöffnet ist, die Außenluft in der Pfeilrichtung (s. Fig. 2) zur Düsenöffnung e gelangt und von hier aus in einem breiten, das Gesicht gänzlich einhüllenden Streifen niederströmt. α the helmet or other headgear, b the umbrella protruding over the face, c is the air line, at one end d of which a hose line connects, while the other end e penetrates the umbrella so that, when the throttle valve f is open the outside air reaches the nozzle opening e in the direction of the arrow (see FIG. 2) and flows down from here in a wide strip that completely envelops the face.
