CA 2218060

A mask (1) for protecting the respiratory system of the wearer comprises a full face mask of a foam material having curved eye pieces (9a, 9b) or a visor, and integral wide bands (5a, 5b) which are wrapped around the wearer's head. The bands (5a, 5b) have respective hook and loop fastening pads (7a, 7b) which are overlapped and fastened together to secure the mask to the wearer's head. The mask (1) includes a face seal (11) to provide a tight seal between the mask and the wearer's face. One way exhalation valves (17a, 17b) are located in the nose and mouth area of the mask, to allow the exhalation of breathed air from the interior of the mask (1) into the environment. The mask (1) includes a filter assembly (19) extending along at least one side of the mask, which provides a passage for air from the environment to the interior of the mask (1). The filter assembly (19), in use, houses a filter (27) which removes particulates and toxins from air drawn through it in response to inhalations of the wearer.

Masque (1) servant à protéger l'appareil respiratoire de l'utilisateur, et comportant un masque intégral en mousse pourvu de viseurs courbés (9a, 9b) ou d'une visière, et de sangles larges (5a, 5b) faisant corps avec le masque et entourant la tête de l'utilisateur. Ces sangles (5a, 5b) possèdent des plaquettes de fixation respectives (7a, 7b) à boucles et crochets, que l'on place l'une sur l'autre pour les relier l'une à l'autre et fixer le masque à la tête de l'utilisateur. Le masque (1) comprend un joint (11) assurant un contact étanche entre le masque et le visage de l'utilisateur. Des clapets anti-retour d'expiration (17a, 17b) se situent dans les zones nasale et buccale du masque et permettent à l'air déjà respiré de passer de l'intérieur du masque (1) au milieu ambiant. En outre, le masque (1) comprend un ensemble filtrant (19) s'étendant sur l'un au moins des côtés du masque et permettant à l'air du milieu ambiant de pénétrer à l'intérieur du masque (1). Lors de son utilisation, cet ensemble filtrant (19) reçoit un filtre (27) qui élimine les matières particulaires et les toxines de l'air qui le traverse sous l'effet de l'inspiration de l'utilisateur.
