A respirator (15) has a harness (10) that allows the respirator body (20) to be conveniently disposed beneath a wearer's chin when not in use. The harness (10) includes a substantially flat, flexible strap (14) and an element (12) that contains a curved elongated slot (16). The subtantially flat, flexible strap (14) is threaded through the curved elongated slot (16). The curved configuration of the slot (16) causes the flat flexible strap (14) to be deformed to assume the curved configuration of the slot. This deformation of the strap (14) allows the strap (14) to frictionally engage element (12), and the frictional engagement allows the respirator body (20) to be incrementally withdrawn from the wearer's face so that it can be temporarily stored beneath the wearer's chin, and allows the respirator body (20) to be conveniently repositioned over the nose and mouth of the wearer by simply pulling on free ends (34) of each strap (14) and joining a buckle (32) behind the wearer's neck.
Un masque respiratoire (15) possède un harnais (10) qui permet de laisser pendre le corps du masque respiratoire (20) sous le menton de l'utilisateur lorsque le masque respiratoire n'est pas utilisé. Le harnais (10) comprend une sangle souple sensiblement plate (14) et un élément (12) qui présente une fente allongée incurvée (16). La sangle souple plate (14) est enfilée à travers la fente allongée incurvée (16). La configuration incurvée de la fente (16) provoque la déformation de la sangle souple plate (14) qui adopte la configuration incurvée de la fente. La déformation de la sangle (14) permet à celle-ci d'avoir un contact par friction avec l'élément (12), et ce contact par friction permet de retirer progressivement le corps (20) du masque respiratoire du visage de l'utilisateur et le laisser temporairement sous le menton de l'utilisateur, puis de repositionner aisément le corps (20) du masque respiratoire sur le nez et la bouche de l'utilisateur en tirant simplement sur les extrémités libres (34) de chaque sangle (14) eten les rattachant à une boucle (32) derrière le cou de l'utilisateur.
