ABSTRACT:
An emergency air supply including a body conforming air supply tank having a reduce dimension in the direction extending outwardly from the user. The air supply tank is preferably formed of a high strength alloy tubular material formed into a closed loop having a closed geometric configuration. This closed geometric configuration may include one or more cross members extending across the central portion of the geometric figure and formed of the same tubular alloy and operatively connected to the closed figure to therefore define a further portion of the tank. The closed figure preferably has a complex shape which conforms to a predetermined portion of the users body, such as the back, chest, hip, thigh or upper arm. Various straps may be associated with the air tank to hold a tank in position upon the users body. An air hose connection nipple is provided upon the tube forming the storage tank such that a standard air hose and fresh air mask may be connected to the nipple to allow the compressed air within the tank to pass through the hose and into the mask for use by the user. Preferably, the nipple extends into the central portion defined by the closed geometric shape to reduce the overall size of the device and to reduce the thickness of the device in a direction extending outwardly from the user's body.
