Abstract
An under helmet hood for aircrew which has a butyl rubber cowl (1) and, severed but in no way displaced therefrom, a face mask portion which includes a face mask (2) having a fixed vizor (3). The perfect butt joint remaining in the butyl rubber between the cowl (1) and the face mask portion is covered by a longitudinally grooved neoprene strip (5), glued in position during manufacture before the cowl is severed, having a rip toggle arrangement which enables tearing of the strip along its groove (9) to be initiated. The face mask portion is then readily ripped out by further tearing of the strip along its groove and separation of the face mask portion at the butt joint. The invention enables reliable protection against all NBC agents and yet at the same time affords excellent rip off facility.
