Abstract

Abstract PARALLEL OPPOSED SHEETS ARE BONDED TOGETHER IN A USHAPED SEAL TO FORM A POCKET. THE POCKET IS INFLATED BY A CONTROLLED AMOUNT, THEN SEALED OFF BY FORMING A NEW POCKET WHEREIN THE BOTTOM OF THE SECOND U-SHAPED SEAL OVERLAPS THE ENDS OF THE FIRST U-SHAPED SEAL. THE SEALED INFLATED POCKET MAY BE FURTHER SUB-DIVIDED INTO SMALLER INFLATED POCKETS BY FURTHER SEALING.
