摘要： There is provided a respiratory protection device comprising a mask body defining a breathable air zone for a wearer and having a front cover; an exhale valve in fluid communication with the breathable air zone; and a seal check mechanism disposed in the front cover, where the seal check mechanism comprises a button associated with a flap such that, when actuated, the flap biases the exhale valve in a closed position. There is provided in some embodiments a plane of the button intersecting with a plane of the exhale valve. There is also provided in some embodiments the button and the plunger being a monolithic part.

摘要： 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.

摘要： A respirator is described that includes a mask body and at least one housing directly or indirectly coupled to the mask body. The at least one housing includes a pair of slots spaced apart from each other, a cantilevered snap feature disposed between the pair of slots, and a latch connected to the cantilevered snap feature. The respirator further includes at least one cover movably coupled to the at least one housing and including a pair of arms. Each of the pair of arms is disposed adjacent to a corresponding slot from the pair of slots and includes a wide end portion. The at least one cover further includes an elongate member extending between the pair of arms and connected to the wide end portion of each of the pair of arms. The elongate member is at least partially received through each of the pair of slots.
