ABSTRACT:
A protective structure is disclosed which provides a compound cushioning effect to impact-loading from an external source. The structure comprises a plurality of cells formed between two layers of plastic film material. The cells contain a sealed-in pneumatic substance which substantially surrounds a core of low density, plastic foam material. Vents may be provided through the layers' intermediate adjacent cells to provide for the flow of air. A cover of fabric material may be provided over the layers of plastic film material depending on the desired use of the structure.
