Title (EN) FILTERING FACE-PIECE RESPIRATOR WITH STIFFENING MEMBER INTEGRAL WITH FILTERING STRUCTURE
(FR) RESPIRATEUR-MASQUE FILTRANT COMPRENANT UN ÉLÉMENT DE RAIDISSEMENT FAISANT CORPS AVEC UNE STRUCTURE-FILTRE
Abstract: front page image
(EN)A filtering face-piece respirator 10 having a mask body 12 formed of a filtering structure 16. The mask body 12 has at least one transversely extending stiffening member 50, formed by an s-shaped or tri-fold pleat permanently connected, such as by welding. The at least one stiffening member 50 increases the integrity of the mask body 12, when in the opened cup-shaped configuration, inhibiting collapse of the mask body, due to, for example, increased pressure drop across the mask body 12 due to dirty or moisture laden air.
(FR)L'invention concerne un respirateur-masque filtrant (10) constitué d'un corps de masque (12) comportant une structure-filtre (16). Le corps de masque (12) comporte au moins un élément transversal de raidissement (50), constitué d'une côte en forme de S ou à trois plis reliés en permanence, par exemple par soudure. Ledit élément de raidissement (50) augmente l'intégrité du corps de masque (12), lorsqu'il se trouve dans la configuration ouverte en forme de coupe, inhibant ainsi l'écrasement du corps de masque, par exemple suite à une chute de pression accrue à travers le corps de masque (12) causée par de l'air sale ou chargé d'humidité.
