Abstract
A loose fitting respirator hood made of flaccid, non-stretchable, air impervious material with a curved optical lens panel interposed in the sidewall thereof. The method of making the hood is disclosed in which curvature is imparted to a relatively stiff lens panel by the flaccid material of the hood. Head engaging members are disclosed for supporting the hood on the head of the wearer. A neck engaging ruff is disclosed which is sealingly mounted about the interior of the hood and can define a hollow annulus with apetures through the sidewall thereof to provide for air distribution to the interior of the hood. A rigid collar member for interconnecting the hood with a suit is disclosed together with the provision of an air filter in communication with a tubular member sealed through the lens panel and extending into proximity with the mouth of the wearer to supply respirable air.
