The first shock absorbing portion 1A and the second shock absorbing portion 1B are arranged such that a plurality of air cells 11 into which air is injected are arranged in a matrix form and each air cell 11 is horizontally And are connected to each other through the communication hole 111 to move the air to the surrounding air cell 11 according to the Pascal principle to disperse the impact,
The first shock absorbing portion 1A provided on the upper portion of the partition wall 3 can absorb an impact generated from the upper portion of the first shock absorbing portion 1A and the second shock It is possible to absorb the impact generated from the lower portion through the absorption portion 1B,
The partition wall 3 is provided with an air cell of the first shock absorbing portion 1A and a second impact absorbing portion 1A so that the impact can be dispersed into the second shock absorbing portion 1B when the first shock absorbing portion 1A is impacted, A vertical through hole 31 is formed so that air is moved between the air cells of the absorbing portion 1B,
The cross-sectional size of the vertical through-hole 31 is smaller than the cross-sectional size of the horizontal communication hole 111,
The first shock absorbing portion 1A and the second shock absorbing portion 1B are formed of a thermoplastic polyurethane (TPU) film and span fibers adhered to each other in a laminated structure (LAMINATE)
When an impact is generated at the upper portion of the first shock absorbing portion 1A, the impact is primarily absorbed by the air injected into the air cell 11 of the first shock absorbing portion 1A,
A plurality of air cells 11 provided in the first shock absorber 1A are absorbed secondarily by moving air to the surrounding air cells 11 through the horizontal communication holes 111 in accordance with the principle of Pascal ,
The air injected into the first shock absorbing portion 1A along the vertical through hole 31 is absorbed by the second shock absorbing portion 1B,
A plurality of air cells 11 provided in the second shock absorber 1B move air to the surrounding air cells 11 through the horizontal communication holes 111 in accordance with the principle of Pascal, Wherein the shock absorbing member is made of a multi-layered air cell.
