Respirator waist belt
A wearable belt for supporting a respiratory component is disclosed. The belt includes a first end portion, a second end portion, and an interface portion that includes an inner layer, an outer layer, and a rigid attachment element in contact with the inner layer and the outer layer. The rigid attachment element is configured to mate with a corresponding feature of a respiratory component.
1. A wearable belt for supporting a respiratory component, comprising:
a wearable belt having a first end portion, a second end portion, and an interface portion between the first and second end portions;
wherein the interface portion comprises an inner layer, an outer layer, a rigid retention element, and a first rigid attachment element in contact with the inner layer and the outer layer and configured to mate with a corresponding feature of a powered air purifying respirator (PAPR) component, and wherein the inner layer, the outer layer, and the first rigid attachment element each define an opening, and the openings are at least partially aligned to form a first common opening extending through the interface portion, and wherein the rigid retention element inhibits flexure of the interface portion about a longitudinal axis of the belt when the belt is fastened on a user.
2. The belt of claim 1 , wherein the rigid attachment element includes one or more flanges extending over a portion of the inner layer and the outer layer.
3. The belt of claim 1 , wherein the rigid attachment element includes an exposed surface configured to contact a corresponding feature of a PAPR component when the PAPR component is releasably secured to the belt.
4. The belt of claim 1 , further comprising a second rigid attachment element, wherein the inner layer, the outer layer, and the second rigid attachment element each define an opening, and the openings are at least partially aligned to form a second common opening extending through the interface portion.
5. The belt of claim 1 , wherein the first rigid attachment element defines a T-shaped opening.
6. The belt of claim 1 , wherein the belt includes four T-shaped openings spaced in a rectangular configuration on the interface surface of the belt.
7. The belt of claim 1 , wherein the first and second end portions each comprise a bumper wing.
8. The belt of claim 1 , wherein the interface portion has a laminated construction.
9. The belt of claim 1 , wherein the first rigid attachment element comprises a plastic injection molded element.
10. The belt of claim 1 , wherein the first rigid attachment element comprises a die-cut element.
11. The belt of claim 1 , wherein the first rigid attachment element is made of high density polyethylene.
12. The belt of claim 1 , wherein the inner layer is a cushioning layer.
13. The belt of claim 1 , wherein the inner layer comprises a material selected from the group consisting of ethylene-vinyl acetate foam, polyvinyl chloride, polyurethane, and rubber.
14. The belt of claim 1 , wherein the outer layer is abrasion resistant.
15. The belt of claim 1 , wherein the outer layer comprises a material selected from the group consisting of ethylene-vinyl acetate foam, polyvinyl chloride, polyurethane, neoprene rubber, and rubber.
16. The belt of claim 1 , wherein the interface portion comprises a lower peripheral edge and the rigid retention element is positioned between the inner layer and the outer layer having a lower edge adjacent to the lower peripheral edge of the interface portion.
17. The belt of claim 1 , wherein the first rigid attachment element and the rigid retention element form a unitary component.
18. The belt of claim 1 , wherein the rigid attachment element and the rigid retention element do not form a unitary component.
