International Classification:

A62B 18/10
A62B 27/00

Abstract:

A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.

A44B 11/00

Abstract:

A buckle assembly for selectively connecting first and second straps of a personal protective device. The buckle assembly includes a receiver member and a latch member configured for coupling to a respective one of the straps. The receiver member defines a slot and provides a release arm. The latch member includes a latch tab pivotally connected to a base. In a latched state in which the latch member is disposed within the slot and a latch face is engaged with a capture surface. The release arm disposed over a portion of the latch tab. The latch face can be disengaged from the capture surface in response to an actuation force applied to the release arm. In some embodiments, the receiver member and the latch member incorporate various, complimentary guide surfaces that promote easy insertion of the latch member into the receiver member.
