Abstract
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.
Claims22
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 configured to releasably attach a strap component of a respiratory harness assembly;
- wherein the first and second suspension attachment protrusions are spaced to releasably attach to a head suspension of a headwear article.
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 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 configured to contact opposing sides of the lateral strap of the hardhat suspension.

A respiratory protection device harness assembly, comprising:
- a hardhat comprising a hardhat suspension configured to support the hardhat on a wearer's head, the hardhat suspension comprising one or more lateral straps positionable on opposing sides of the wearer's head during use;
- a respirator comprising a harness assembly, the harness assembly including first and second strap portions on opposite sides of the respirator;
- a first unitary harness adapter including means for releasably attaching the first unitary harness adapter to the lateral strap of the hardhat suspension and means for releasably attaching the first unitary harness adapter to the first strap portion;
- and
- a second unitary harness adapter including means for releasably attaching the second unitary harness adapter to the lateral strap of the hardhat suspension and means for releasably attaching the second unitary harness adapter to the second strap portion.
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 attachment elements configured to releasably attach to the first or second lateral strap portions of the harness assembly;
- wherein the first and second harness attachment elements are integral with the lateral strap and form an angle with the lateral strap that is less than 90°.
