FILTERING FACE-PIECE RESPIRATOR THAT HAS EXPANDABLE MASK BODY
摘要
<p>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.</p>
