A respiratory mask is provided with an eye shield having a body portion which is releasably-secured to the mask, and a shield portion which shields the eyes of the wearer. The shield portion is self-supporting on the body portion and, hence, on the mask, and includes a sheet of transparent, eye-shielding, material which can be replaced is it becomes marked or damaged. The shield portion can be pivoted forwards, relative to the mask, so that it is removed from the line of vision of the wearer without affecting the respiratory protection provided by the mask. A valve arrangement in the body portion of the eye shield can divert air from the mask into the shield portion, to remove contaminants from the region around the eyes of the wearer.
Un masque respiratoire est muni de protections oculaires dont le corps peut être détaché du masque et d'un élément protecteur des yeux du porteur. L'élément protecteur qui s'adapte au corps et donc au masque comporte une feuille d'un matériau transparent de protection de l'oeil remplaçable si marquée ou endommagée. La partie protectrice peut pivoter vers l'avant par rapport au masque de manière à quitter le rayon visuel du porteur sans affecter la protection respiratoire offerte par le masque. Une soupape disposée dans le corps de la protection oculaire peut faire passer l'air occlus dans le masque vers les éléments protecteurs pour éliminer les substances contaminantes de la zone périoculaire.
