Abstract

Various embodiments described herein are directed to a face mask assembly configured with a drop-down feature and methods of using the same. In various embodiments, a face mask assembly comprises a face mask configured for dynamic engagement with a first strap of a strap assembly such that the face mask is configured for selective movement along a strap length of the first strap between a donned position and a drop-down position, the face mask comprising: a first strap pathway configured to receive at least a portion of the first strap and a strap engagement tongue positioned along the first strap pathway and comprising a plurality of strap engagement teeth protruding from of the interior tongue surface; wherein the face mask is configured to be selectively adjustable between a dynamic configuration and a locked configuration based on the arrangement of the first strap relative to the strap engagement tongue.

First claim

That which is claimed:

1 . A face mask assembly configured with a drop down feature, the face mask assembly comprising:
a face mask configured for dynamic engagement with at least a first strap of a strap assembly such that the face mask is configured for selective movement in one or more directions along a strap length of the first strap between a donned position and a drop-down position, the face mask comprising:
a first strap pathway comprising an exterior pathway surface positioned on a first lateral side of the face mask, the first strap pathway being configured to receive at least a portion of the first strap along the exterior pathway surface; and
a strap engagement tongue defined by a material thickness extending between an exterior tongue surface and an interior tongue surface, the strap engagement tongue comprising a plurality of strap engagement teeth protruding from of the interior tongue surface;
wherein the strap engagement tongue is positioned along the first strap pathway such that the exterior tongue surface defines at least a portion of the exterior pathway surface of the first strap pathway;
wherein the face mask is configured to be selectively adjustable between a dynamic configuration and a locked configuration relative to the first strap based at least in part on the arrangement of the first strap relative to the strap engagement tongue; and wherein, in the locked configuration, the plurality of strap engagement teeth are configured to provide frictional resistance to the first strap to resist the movement of the face mask relative to the strap length of the first strap.

2 . The face mask assembly of claim 1 , wherein the face mask is dynamically engaged with the strap assembly via a connection of the first strap to a face mask cover of the face mask, wherein the first strap pathway is defined along an exterior surface of the face mask cover.

3 . The face mask assembly of claim 2 , further comprising:
a face engagement component configured to engage a face of a user at a seal interface that extends along a perimeter of an open end of the face engagement component; and wherein the face engagement component and the face mask cover define distinct components configured to be removably attached to one another.

4 . The face mask assembly of claim 2 , further comprising:
a second strap pathway comprising a second exterior pathway surface defined along the exterior surface of the mask cover and positioned on a second lateral side of the face mask, the second strap pathway being configured to receive at least a portion of a second strap of the strap assembly along the second exterior pathway surface such that the face mask is configured for selective movement in one or more directions along a second strap length of the second strap; and a second strap engagement tongue defined by a second material thickness extending between a second exterior tongue surface and a second interior tongue surface, the second strap engagement tongue comprising a second plurality of strap engagement teeth protruding from of the second interior tongue surface; wherein the second strap engagement tongue is positioned along the second strap pathway such that the second exterior tongue surface defines at least a portion of the second exterior pathway surface of the second strap pathway; and wherein, in the locked configuration, the second plurality of strap engagement teeth are configured to provide frictional resistance to the second strap to resist the movement of the face mask relative to the second strap length of the second strap.

5 . The face mask assembly of claim 1 , wherein the first strap is defined along the strap length between a first strap end and a second strap end, wherein the first strap end and the second strap end of the first strap are each configured for attachment to a head support component of the strap assembly such that the first strap defines a closed-loop strap portion including an intermediate strap portion defined in between the first strap end and the second strap end, and wherein the first strap pathway is configured to receive the first strap at the intermediate strap portion such that the selective movement of the face mask between the donned position and the drop-down position is at least partially defined within the close-loop strap portion of the first strap.

6 . The face mask assembly of claim 5 , wherein a second strap of the strap assembly is defined along a second strap length between two opposing strap ends, wherein both of the two opposing strap ends of the second strap are configured for attachment to the head support component of the strap assembly such that the second strap defines a second closed-loop strap portion including a second intermediate strap portion defined in between the two opposing strap ends, and wherein the second strap pathway is configured to receive the second strap at the second intermediate strap portion such that the selective movement of the face mask between the donned position and the drop-down position is defined at least partially within the second closed-loop strap portion of the second strap.

7 . The face mask assembly of claim 1 , wherein the first strap pathway comprises a strap pathway protrusion further comprising a material protrusion extending from a first lateral side edge of the first strap pathway in a width direction towards a second lateral side edge of the first strap pathway, wherein the strap pathway protrusion s configured to physically engage the first strap in order to provide frictional resistance to the first strap to resist the movement of the face mask relative to the strap length of the first strap.

8 . The face mask assembly of claim 7 , wherein the strap pathway protrusion is arranged in a position along the first strap pathway that is at least substantially aligned with at least a portion of the strap engagement tongue.

9 . The face mask assembly of claim 8 , wherein the strap pathway protrusion and the strap engagement tongue are provided at a central portion of the first strap pathway, the central portion being defined by a midpoint along a strap pathway length of the first strap pathway at least approximately halfway between a first strap pathway end and a second strap pathway end.

10 . The face mask assembly of claim 1 , wherein the first strap pathway extends along a strap pathway length between a first strap pathway end and a second strap pathway end, and wherein the first strap pathway further comprises a second plurality of strap engagement teeth protruding from of the exterior pathway surface at the second strap pathway end of the first strap pathway.

11 . The face mask assembly of claim 10 , wherein the second strap pathway end of the first strap pathway is defined by a bottom end of the first strap pathway positioned at least substantially adjacent a bottom edge of the face mask.

12 . The face mask assembly of claim 10 , wherein the second plurality of strap engagement teeth are configured to protrude from the exterior pathway surface in an at least substantially outward direction away from the face mask so as to provide frictional resistance to a bottom surface of the first strap to resist the movement of the face mask relative to the first strap length of the first strap.

13 . The face mask assembly of claim 10 , further comprising:
a second strap pathway comprising a second exterior pathway surface defined along the exterior surface of the mask cover and positioned on a second lateral side of the face mask, the second strap pathway being configured to receive at least a portion of a second strap of the strap assembly along the second
