  • Patent number: 5078130
    Abstract: Protective headgear with a face shield which can be tilted up out of the way, and which when tilted downwardly can be placed in a standby position enabling free breathing of ambient air through a gap between a helmet and the face shield, and can be pressed back to create a seal to require breathing from a controlled source. A selector is mounted on the face shield to enable the wearer to make a quick and effective selection of breathing modes. A face seal can be mounted to the inside of the face shield to form an oro-nasal dam around the nose and mouth of the wearer to provide another seal, and a reduced plenum volume.
