    摘要： A filtering face-piece respirator 10 that includes a mask body 12 and a harness 14. The mask body 12 contains a filtering structure 18 that is retained in position on the mask body 12 by a support structure 16 that includes a longitudinally-movable, centrally-spaced, transversely-extending member 26 that extends from a first side 22 of the structure 16 to a second side 24 without being joined together by any longitudinally-extending members that hinder movement of the transversely extending member 26 in the longitudinal direction. The transversely-extending members converge towards each other at east side 22, 24 of the mask body 12. A filtering face-piece respirator 10 of this construction can allow the mask body 12 to readily accommodate the motion of a person's jaw. Workers who use this filtering face-piece respirator may find it much easier to talk to other persons when working. A single mask size also may be able to properly fit to faces of various sizes.

    摘要： A respirator 10 that comprises a mask body 32 and a nose foam 10. The mask body 32 is adapted to fit over the nose and mouth of a person and has an interior surface 34. The nose foam 10 has a rear side 24, a front side 26, a rear side 24, and is secured to the interior surface 34 of the mask body 32 at a mask contacting surface 12. The nose foam 10 also has a central portion 14 and first and second side-contacting portions 16 and 18 that are symmetrically located on opposing sides of the central portion. The nose foam further has a nose-contacting surface 20 that extends over the central portion 14 and the first and second side-containing portions 16, 18. The nose-contacting surface 20 is skewed at first and second angles α to a plane 22 that cuts through the nose foam orthogonally to its lengthwise dimension. A nose foam of this construction can provide a snug fit to a wearer's face in the nose region without having to use a nose clip.
