Abstract

A system for providing streaming air to evaporate perspiration from a wearer of personal armour. The system incorporates a set of voluminous layers for wearing beneath the armour, one of which is enveloped voluminous layer. The envelope is perforated in the direction of said wearer, such that an air blower forces air into the perforation and thence onto the body of the wearer.

Claims

1. A system for providing streaming air to evaporate perspiration from a wearer of a personal armour, wherein a set of voluminous layers is worn beneath said armour, said set comprising:

at least one enveloped voluminous layer, and wherein the shell enveloping said layer is perforated in the direction of said wearer, and

an air blower for forcing air into said outer enveloped layer.

2. A system for providing streaming air to evaporate perspiration from a wearer as in claim 1 further comprising a body contact layer between said enveloped layer and said wearer.

3. A system for providing streaming air to evaporate perspiration from a wearer as in claim 1 further comprising an air hose to connect said air blower with said enveloped layer.

6. A system for providing streaming air to evaporate perspiration from a wearer as in claim 1 wherein said at least one enveloped voluminous layer contains volume providing elements.

7. A system for providing streaming air to evaporate perspiration from a wearer as in claim 6 wherein said volume providing elements are any selected from a group consisting of foam, fibers, three dimensional net and mechanical spacers.

8. A system for providing streaming air to evaporate perspiration from a wearer as in claim 2 wherein said body contact layer contains volume providing elements.

9. A system for providing streaming air to evaporate perspiration from a wearer as in claim 8 wherein said volume providing elements are any selected from a group consisting of foam, fibers, three dimensional net and mechanical spacers.

4. A method for cooling the skin of a wearer of personal armour wherein air is forced from an air blower to an enveloped voluminous layer disposed beneath said personal armour, and wherein said air is forced out of said layer in the direction of the body of said wearer, providing a flow of air over said skin of said wearer.

5. A method for cooling the skin of a wearer of personal armour as in claim 4, and wherein said air forced out of said enveloped layers enters a voluminous body contact layer before being applied to said wearer.
