ABSTRACT:
The full face flexible oxygen mask for use with flight helmets includes an elastic face seal with an oronasal cone that seals around the nose and mouth of the wearer, and flexible sealing flaps along the perimeter of the face seal to adapt the face piece of the mask to seal against the surface of a flight helmet. The mask face piece has two large sealing surfaces or channels down each side of the mask that overlap and flex to adapt to seal to a variety of flight helmets. The top of the face seal has an inner and outer flap that work together to seal the exposed face visible between the sides of the flight helmet.
