SELF-COMPENSATING THERMAL INSULATION GARMENTS

摘要

Self-compensating thermal insulating garments are found useful for protecting the body of a user from hostile temperature environments. The garments each comprise a plurality of compartments with each compartment having a heat insulating core of a flexible porous material. Outer and inner continuous resilient sheets span the compartments and preferably seal the cores against unwanted passage of gas and liquid in conjunction with barrier means for each compartment which form gas and water barriers. Preferably tubular means pass into and through the cores to deliver a gas at a predetermined pressure to maintain each of the compartments at predetermined internal pressures preventing compression of the compartments due to pressure differentials.
