FILTERING FACE-PIECE RESPIRATOR HAVING BUCKLES INTEGRAL TO THE MASK BODY SUPPORT STRUCTURE |
摘要 |
A filtering face-piece respirator 10 that includes a mask body 12 and a harness 14 and a support structure 16. The support structure 16 has a perimeter 20 that includes buckles 40 that are integrally joined to the perimeter 20. A mask body of this construction avoids the need to separately make the buckles and the mask body support structure and avoids an additional step in the assembly of the respirator.
