Abstract

La présente invention se rapporte à un masque respiratoire simplifié, qui sert à protéger les yeux d'une personne évoluant les yeux ouverts dans l'eau ou dans de la fumée lors du naufrage d'un bateau ou lors d'un incendie d'un bâtiment et qui sert à fournir de l'air ou de l'oxygène, nécessaire à la respiration de l'utilisateur, pendant une période prédéterminée, tout en laissant les deux mains de l'utilisateur libres. Le masque respiratoire simplifié de la présente invention comprend des lunettes destinées à être placées sur le visage de l'utilisateur de façon à être en contact étroit avec le visage et à couvrir les organes, tels que les yeux et le nez ou tels que les yeux, le nez ou la bouche; des régulateurs de pression (5) fixés à la monture (1) des lunettes et contenant des raccords (11) reliés à des entrées d'air de bouteilles sous haute pression miniaturisées et remplaçables (6), un organe de dépressurisation (14) et un organe de sécurité (13); ainsi qu'un régulateur d'air d'aspiration (10) disposé entre les parties interne et externe de la monture (1) des lunettes et destiné à fournir un gaz d'alimentation depuis les régulateurs de pression vers l'intérieur des lunettes en utilisant la différence entre la pression externe et la pression de respiration de l'utilisateur.
