Title:
RESPIRATOR HARNESS HAVING COLLAPSIBLE HEAD CRADLE
Document Type and Number:
WIPO Patent Application WO/2011/112401
Kind Code:
A3
Abstract:
A respirator (10) that includes a harness (12) and a mask body (14). The harness (12) has one or more straps (21) and a head cradle (16) that is joined to the one or more straps (21) and that includes first and second laterally-extending members (18, 20) and a latch (26). The latch (26) is able to secure the laterally-extending members (18, 20) in a spaced apart first open position to allow for placement on a person's head and is able to disengage so that the members (18, 20) can move to a second collapsed position to allow for off-the-face storage. The harness is beneficial in that it can be quickly removed from the wearer's head and can be conveniently disposed behind the wearer's neck when the wearer wants to temporarily displace the mask body from their face.
