1. An air cell device, comprising:
an air cell having two long sides, two height sides, and two short sides defined by an air cell wall when the air cell is inflated, the air cell wall having a left air cell wall and a right air cell wall which are defined on two sides of the long sides; and
an air transfer unit in fluid communication with an inside of the air cell and an outside of the air cell to transfer air,
wherein the air cell has an upper connection segment and a lower connection segment extending along the long side direction, which are formed by directly joining of the left air cell wall and the right air cell wall, allowing inner surfaces of the left and right walls to be in direct contact, the upper and lower connection segments partitioning the inside of the air cell into three chambers extending along the long side direction,
wherein the upper connection segment and the lower connection segment each have at least one curved portion by arranging a plurality of positions where the left air cell wall and the right air cell wall to be directly joined, thereby causing the cross-sectional area of each chamber to vary along the long side direction.
