Personal body ventilation system
First Claim
1. A garment for selectively supplying air under pressure to an area of the body of a wearer comprising:
- an inner layer adapted to be disposed closer to the body of the wearer;
said inner layer formed of material impervious to air;
said inner layer including an opening therethrough;
an outer layer disposed on top of said inner layer;
said outer layer formed of material impervious to air;
porous means joined to at least one of said inner layer and said outer layer and positioned adjacent said opening in said inner layer to provide a porous surface adjacent the area of the body to which air is intended to be supplied; and
an air inlet for receiving air under pressure;
said inner layer, said outer layer and said porous means being sealed at the peripheral edges thereof such that said garment is impervious to air except for said porous surface whereby air is expelled from the garment under pressure through said porous surface.

Abstract
A personal body ventilation system includes a battery powered blower for providing air under pressure to the interior of a disposable garment formed by an inner air impervious layer and an outer air impervious layer. Porous-to-air open celled foam is incorporated into the garment at areas where cooling is desired and provides porous surfaces adjacent the body of the wearer from which the air under pressure in the interior of the garment may be directed against the body of the wearer. The system includes a filter arrangement in which a filter incorporated in the garment filters the ambient air prior to being drawn into the blower. The blower, the ouput of which is coupled to the garment in the rear by an elliptical connection, includes miniature radial turbine fans operating under a variable speed control. The circulated air may be heated or cooled or treated in various manners such as filtering or humidifying/dehumidifying to meet the requirements of the specific user environment.
