ABSTRACT:
An air supplying hood has a top wall, to which the upper edge of a flexible plastic front wall is connected, with the upper portion of the front wall forming a transversely curved front window. A flexible back wall behind the window is connected with the top wall and the sides of the window to form with the window an open-bottom enclosure for a person's head. The lower portion of the flexible back wall and the front wall below the window form areas shaped to fit over a person's shoulder and lie against his chest and back. Above those areas is a hollow band extending around the hood and communicating with the lower ends of circumferentially spaced hollow vertical struts with which the wall of the head enclosure is provided. The band and struts are inflatable by an air tube extending through the back wall for supplying air to the head enclosure.
