Headwear suspension attachment element
The present description provides components that allow a respiratory protection device to be secured in a position of use by attachment with a headwear suspension. In some exemplary embodiments, a harness adapter is positioned along a strap of a headwear suspension and includes a harness attachment element that may releasably attach to a strap component of a respiratory harness assembly.
1. A respiratory protection device harness adapter, comprising:
first and second major surfaces having an upper edge region and a lower edge region;
a first suspension attachment protrusion proximate the upper edge region;
a second suspension attachment protrusion proximate the lower edge region; and
a harness attachment element comprising a hook and configured to releasably attach a strap component of a respiratory harness assembly;
wherein the first and second suspension attachment protrusions are spaced and configured to releasably attach to a head suspension of a headwear article, the adapter further comprising a strap attachment element and wherein the strap attachment element further comprises a loop, and the hook is connectable with the loop.
2. The adapter of claim 1 , wherein the harness attachment element extends downwardly from the lower edge region.
3. The adapter of claim 1 , wherein the first and second suspension attachment protrusions extend outwardly from the first major surface.
4. The adapter of claim 1 , wherein the first suspension attachment protrusion is configured to attach around an upper edge of the head suspension of the headwear article.
5. The adapter of claim 1 , wherein the first and second suspension attachment protrusions are spaced to define a channel configured to receive the head suspension of the headwear article.
6. The adapter of claim 1 , wherein the second major surface is configured to contact a wearer's head and is free of projections extending from the second major surface.
7. The adapter of claim 1 , wherein the first and second major surfaces are separated by a thickness (t), and the thickness (t) is between 0.25 mm and 4 mm.
8. The adapter of claim 1 , further comprising a lateral stability element configured to contact the head suspension of the headwear article and prevent relative motion between the head suspension and the adapter along a longitudinal axis of the head suspension.
9. The adapter of claim 8 , wherein the lateral stability element comprises a post configured to extend through an opening in the head suspension.
10. The adapter of claim 8 , wherein the lateral stability element comprises an adhesive.
11. The adapter of claim 1 , wherein when the adapter is attached to the head suspension, the hook is angled relative to a vertical axis.
12. The adapter of claim 3 , wherein the first major surface is configured to contact an inner surface of the head suspension.
13. A respiratory protection assembly, comprising:
a hardhat comprising a hardhat suspension configured to support the hardhat on a wearer's head, the hardhat suspension comprising a lateral strap configured to extend at least partially along a side of a wearer's head;
a respirator comprising a harness assembly, the harness assembly including first and second strap portions on opposite sides of the respirator; and
first and second harness adapters, each comprising:
first and second major surfaces having an upper edge region and a lower edge region;
a first suspension attachment protrusion proximate the upper edge region;
a second suspension attachment protrusion proximate the lower edge region; and
a harness attachment element comprising a hook and extending downwardly from the lower edge region and configured to releasably attach to the first or second strap portions of the harness assembly;
wherein the first and second suspension attachment protrusions are spaced and configured to releasably attach to the hardhat suspension of the hardhat and configured to contact opposing sides of the lateral strap of the hardhat suspension wherein, for both the first and second harness adapters, the lateral strap comprises a loop, and the hook is connectable with the loop.
14. The respiratory protection assembly of claim 13 , wherein, for both the first and second harness adapters, the first and second suspension attachment protrusions extend outwardly from the first major surface.
15. The respiratory protection assembly of claim 13 , wherein the first harness adapter is a mirror of the second harness adapter.
