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.
