20090078268 | BUCKLE HAVING A FLEXURAL STRAP ATTACHMENT MEMBER AND RESPIRATOR USING SUCH BUCKLE - 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. | 03-26-2009 |

The cinch bar then returns to a closed position and supports the strap over the cinch bar. The cinch bar may be deformable through the use of a living hinge connecting the cinch bar to the body of the buckle. The cinch bar may be split into two members, each being deformably coupled to the buckle body, perhaps with living hinges. | 08-06-2009 |
