    摘要： Respirator and buckle having a flexural member allowing the buckle to move in three dimensions, potentially improving user comfort, the effectiveness of the respirator, and allowing for more precise adjustments to be made to the fit of the respirator on the user. The flexural member may be a three dimensional living hinge. By lifting on the buckle, the straps that secure the respirator to the user are released and the ability of the buckle to move in three dimensions tends to increase the situations in which the adjustment may occur. Various types of three dimensional living hinges may be utilized, including a cylindrical hinge and a serpentine hinge.

    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.
