Abstract
Breathing apparatus including headgear comprises a helmet (1, 11), a breathable gas supply connected to the helmet, a flexible bag (2, 14) stowable in a restrained ''non-ballooning'' position in the neck region (3, 13) of the helmet (1, 11) is connected directly without hose lines to the helmet and may be deployed by tugging upon grip (7, 17) attached by cord (8, 18) to releasable retaining means (6, 16) and inflated by helmet gas pressure to provide a re-breathable volume of gas. A CO2 scrubber canister (-, 21) is attached directly to the helmet (1, 11) and the said helmet is supplied with O2- rich gas from a cylinder on a back pack. The canister and cylinder are sealed during normal use of the apparatus and are brought into use only with the re-breather bag (2, 14) under emergency ''bail-out'' conditions.
