Abstract: A strap retaining device having an actuation arm that may engage a retaining tab is provided. In an exemplary embodiment, the strap retaining device includes a frame, a retention tab pivotally connected to the frame, and an actuation arm connected to the frame and having a first actuation element movable towards the retention tab from a neutral position to an actuated. The first actuation ramp is movable in a first plane to cause the retention tab to move in a second plane that is perpendicular to the first plane.

Abstract: A respirator apparatus includes a respirator body, a filter cartridge receiver integral with and extending from the respirator body, and a filter cartridge. The filter cartridge includes a nozzle element being integral with the filter cartridge. The respirator body and filter cartridge are configured to be fluidically coupled through sleeve-fit engagement between the filter cartridge receiver and nozzle element and the filter cartridge receiver and nozzle element define an airflow channel.

Abstract: A respirator 10 that has a mask body 12 and a harness 16 has an exhalation valve 23 that includes a valve seat 36 and a flexible flap 42. The valve seat 36 has an orifice 38 and has a noncircular seal surface 40 surrounding the orifice 38. The flexible flap 42 is secured to the valve seat 36 at a centroid of the orifice and has a variable stiffness structure. The variable stiffness structure allows the flap to equally deflect under a given load at different distances from the centroid at the noncircular seal surface. An exhalation valve having this construction may beneficially optimize pressure drop and overall valve performance for applications where valve space may be limited.
