Abstract

A protective garment system including a bib configured to fit around at least part of an upper portion of a torso of a wearer. The bib includes an outer material and a particulate-blocking material which is configured to be positioned between the outer material and a wearer when the bib is worn. The bib has a perimeter and is configured to be releasably attached to a pair of trousers about the perimeter.

First claim

What is claimed is:

1. A protective garment system comprising:
a bib configured to fit around at least part of an upper portion of a torso of a wearer, wherein said bib includes an outer material and an air-permeable particulate-blocking material which is configured to be positioned between said outer material and the wearer when said bib is worn, wherein said bib has a perimeter, wherein the particulate-blocking material is configured to block particulates and has a plurality of pores formed therein to provide air permeability, having an average pore size of less than about 10 microns, and wherein the particulate-blocking material is made of flame-resistant meta-aramid material or includes flame-resistant meta-aramid material.

2. The protective garment system of claim 1 wherein the particulate-blocking material is generally coextensive with the outer material and wherein said bib further includes an inner face cloth layer, and wherein said particulate-blocking material is generally positioned between said outer material and said inner face cloth layer.

3. The protective garment system of claim 1 wherein said bib lacks a moisture barrier, where such moisture barrier is configured to permit moisture vapor to pass therethrough and configured to block liquids from passing therethrough.

4. The protective garment system of claim 1 wherein said bib has a thermal protection performance of less than about ten.

5. The protective garment system of claim 1 wherein said bib includes releasable fastener extending about or positioned adjacent to a lower edge of said bib and extending continuously at least about 360 degrees about the entire perimeter of the bib.

6. The protective garment system of claim 1 wherein said bib is sleeveless.

7. The protective garment system of claim 1 wherein the bib includes a back portion configured to be positioned adjacent to a back of the wearer when worn and two front portions each of which is configured to be positioned adjacent to a front of the wearer when said bib is worn, and wherein the front portions are releasably attachable to each other.

8. The protective garment system of claim 7 wherein the bib includes a pair of stretch portions, each of which is generally positioned between said back portion and one of said front portions, wherein each stretch portion includes the particulate blocking material.

9. The protective garment system of claim 8 wherein the particulate-blocking material of the stretch portions are elastic, and wherein the bib further comprises a pair of attachment straps, wherein each attachment strap is releasably attachable to said bib in a position where the attachment strap spans one of said stretch portions, and wherein said bib further includes a pair of shoulder straps, each of which is configured to fit over a shoulder of the wearer when said bib is worn.

10. The protective garment system of claim 1 wherein the particulate-blocking material has a thickness of less than about 15 mils.

11. The protective garment of claim 1 wherein the particulate-blocking material has an air permeability of less than about 30 cfm.

12. The protective garment of claim 1 wherein the particulate-blocking material has a basis weight of less than about 1 oz/square yard.

13. The protective garment of claim 1 wherein the particulate-blocking material lacks any pores having a size greater than 100 microns, and has a barrier efficiency of greater than 95% for particles greater than 1 micron.

14. The protective garment system of claim 1 wherein the bib is configured to be releasably attached to a pair of trousers about at least part of the perimeter.

15. The protective garment system of claim 14 further comprising said pair of trousers, and wherein said bib is releasably and continuously coupled to said pair of trousers 360 degrees about an entire perimeter of the trousers.

16. The protective garment system of claim 15 further comprising a firefighter protective coat which is wearable separable from said bib, and wherein said bib is generally positioned between said coat and the wearer.

17. A protective garment system comprising:
a bib configured to fit around at least part of an upper portion of a torso of a wearer, wherein said bib includes an outer material and an air-permeable particulate-blocking material which is configured to be positioned between said outer material and the wearer when said bib is worn, wherein the particulate-blocking material is made of a microfiber filament material or includes a microfiber filament material.

18. A protective garment comprising:
a bib configured to fit around at least part of an upper portion of a torso of a wearer, wherein said bib includes an outer material and an air-permeable particulate-blocking material which is configured to be positioned between the outer material and the wearer when the bib is worn and wherein the bib is sleeveless, has a thermal protection performance less than about 10, and lacks a moisture barrier that is configured to permit moisture vapor to pass therethrough but block liquids from passing therethrough.

19. The protective garment of claim 18 wherein the particulate-blocking material is configured to block particulates, has a plurality of pores to provide the air permeability, and has an air permeability of less than about 30 cfm.

20. The protective garment of claim 18 wherein said bib includes releasable fastener extending about or positioned adjacent to a lower edge of said bib and extending continuously at least about 360 degrees about an entire perimeter of the bib.

21. A protective garment comprising:
a bib configured to fit around at least part of an upper portion of a torso of a wearer, wherein said bib includes an outer material, an inner material and a particulate-blocking material which is not a moisture barrier and is configured to be positioned between said outer material and said inner material when said bib is worn, wherein the particulate-blocking material is configured to block particulates, has a thickness of less than about 15 mils, and has an air permeability of less than about 30 cfm.

22. The garment of claim 21 wherein said bib has a perimeter at or adjacent to a lower edge thereof and is configured to be continuously coupled to a pair of trousers 360 degrees about an entire perimeter of the trousers, wherein said bib is sleeveless, wherein said bib has a thermal protection performance less than about 10, and wherein said bib lacks a moisture barrier that is configured to permit moisture vapor to pass therethrough and configured to block liquids from passing therethrough, and has an average pore size of less than about 100 microns.

23. The garment of claim 21 , wherein the particulate-blocking material has a plurality of pores formed therein to provide the air permeability, having an average pore size of less than about 10 microns.

24. The garment of claim 21 wherein the particulate-blocking material is made of flame-resistant meta-aramid material or includes flame-resistant meta-aramid material, or wherein the particulate-blocking material is made of a microfiber filament material or includes a microfiber filament material.
