  • Stress deformable and sealed breathing mask
    Patent number: 8910634
    Abstract: A stress deformable and sealed breathing mask that includes an air permeable rectilinear mask body having at least one layer of air filtering material and a resilient sealing strip at an upper edge of the mask body for sealing engagement with a user's face. An upper attachment strap is in a laced engagement with the mask body and the resilient sealing strip such that tightening of the upper attachment strap about a user's head causes the resilient sealing strip to resiliently deform substantially to the contour of the user's face in the bridge area of the user's nose. A lower attachment strap secures the bottom of the mask body against a portion of the user's face below the user's mouth.
