Claims

[Claims for Utility Model Registration] 1. Individually segmented inflatable airbags;
an air injection tube that penetrates through each air bag and is sealed at both ends of each air bag, and has a flat valve structure at a portion located inside the air bag, and the flat valve structure allows the air injection tubes to make surface contact with each other. A pore is formed on one of the two sides, and the pore is opened by air pressure from inside the air injection tube to introduce air from inside the tube into the air bag, and the air pressure filling the air bag causes the pore to be opened by air pressure from inside the air injection tube.
A connected airbag type cushioning material having a flat valve structure, characterized in that it closes when its surface is pressed. 2. The connected air bag type cushioning material according to claim 1, wherein the air bag is formed by folding a rectangular rubber or plastic film in half and bonding the three combined sides together by adhesive or heat fusion. 3. The air bag is formed as a series of individually segmented air bags by heat-sealing the bag-like material crosswise at predetermined intervals from above through an air injection tube passed through a continuous bag-like material. The connected air bag type cushioning material according to item 1. 4. The connected air bag type cushioning material according to claim 2 or 3, wherein the injection tube passes through two opposing sides of the air bag and is heat-sealed to the air bag, but the inner surfaces of the injection tube are not fused to each other. 5. The connected airbag type cushioning material according to claim 4, wherein the injection tube is a plurality of tubes arranged in parallel and penetrating the airbag. 6. A flat valve structure formed in an injection tube that passes through and connects each inflatable air bag, with a slit formed in one of the two flat surfaces of the injection tube located inside the air bag so that the injection tube can make surface contact with each other. Or a flat valve structure consisting of a pore consisting of a slot and another flat surface that can be in pressure contact with the flat surface near the pore.
