A respirator hood (1) that has an air chamber (6) arranged above the head of a user for delivery of breathable air. The air chamber (6) has an air inlet (13) connected to an air supply hose (5) and an air outlet (17). The outlet (17) is arranged to direct air away from the eyes of the user. The air chamber (6) forms an air duct (12) that substantially covers the top of the hood (1) above the user's head. The duct (12) is collapse-resistant so that the duct shape is maintained in use and air flow through the duct (12) is substantially unrestricted. As a result, a substantially uniform air flow can be achieved in use, which air flow pattern is repeatable from day to day and from hood to hood.

L'invention concerne une cagoule (1) respiratoire équipée d'un réservoir (6) à air placé au-dessus de la tête de l'utilisateur et destiné à fournir de l'air respirable. Ledit réservoir (6) à air est doté d'une admission (13) d'air reliée à un tuyau d'amenée (5) d'air et d'une sortie (17) d'air. Ladite sortie (17) d'air est conçue pour éloigner l'air des yeux de l'utilisateur. Ledit réservoir (6) à air forme une conduite (12) d'air qui recouvre sensiblement le sommet de la cagoule (1) au-dessus de la tête de l'utilisateur. Ladite conduite (12) est résistante à l'affaissement, sa forme restant donc utilisable, et le flux d'air la traversant ne subit sensiblement aucune perturbation. On obtient ainsi un flux d'air sensiblement uniforme, sa configuration pouvant donc se répéter d'un jour à l'autre et d'une cagoule à l'autre.
