Abstract

The combination noise suppression and breathing respirator of the present invention includes a face mask of the snorkel or diving type, the facemask sealing against the face of the user around the nose, cheeks, eyes and forehead of the wearer. The facemask has a nosepiece having an exhalation flap check valve for exhalation by the user. Each side of the face mask has a one-way inlet valve at a connection which connects with rearward extending dual use air channel and straps. A noise suppression and air filter module is worn over each ear of the user and is attached to respective dual use air channel and straps. Head bands extend around the back of the wearer'"'"'s head between air filter modules an adjustably connected by buckles thereto.

Claims

1. A combination hearing protector and breathing respirator, comprising:

a face mask having a front lens having a side lens on each side thereof, a face conforming sealing body having a nose conforming portion, a frame supporting said lenses and said sealing body, an exhalation flap check valve located on said nose portion, and a supporting frame for supporting said lenses and said sealing body, said frame having opposed side portions, and a one-way check valve module located in each of said frame side portions;

said face mask defining a plenum chamber between said face mask and the face of the user;

a dual purpose air channel and facemask strap connected with each of said frame side portions and extending rearward therefrom, each said air channel being in one-way fluid communication with said plenum chamber through said one-way check valve modules;

a pair of air filter and noise reduction modules each having a sealing frame for sealing over the respective ears of the user, an air inlet grid extending outward from said sealing frame, said sealing frame having outlet air channel connections connected with said rearward extending dual purpose air channel and facemask straps, said air inlet grid being in fluid communication through said outlet air channels and thus said dual purpose air channel and facemask straps;

said sealing frame having rearward mounted buckles; and

a head band extending between said sealing frame buckles for extending around the back of the user'"'"'s head;

whereby noise suppression is accomplished by said air filter and noise suppression modules when worn by a user; and

whereby air for breathing through the use'"'"'s nose travels through said air filter and noise suppression modules, said dual purpose air channel and facemask straps, said one-way check valves, and into said plenum chamber upon breathing in by the user, and exhausted breath exits said plenum chamber through said nose portion mounted exhalation flap check valve upon exhalation by the user.

2. The combination hearing protector and breathing respirator, of claim 1, said noise suppression filter module having a layered paper filtration medium.
