The cushion part 2 is arranged on the upper side of the air bag fixing cushion 11, the cushion part 2 is provided with a pre-sitting area, through holes 4 penetrating through the cushion part 2 and the air bag fixing cushion 11 are arranged at positions corresponding to the pre-sitting area on the cushion part 2 and the air bag fixing cushion 11, the air bag unit 12 is not arranged in the through hole 4 area, namely, on the lower side surface of the air bag fixing cushion 11, and the area outside the through holes 4 is an air bag distribution area.

Referring to fig. 2, in one embodiment, the adjusting portion 1 includes twenty-three airbag units 12, the twenty-three airbag units 12 are uniformly spaced in an airbag distribution area, and two adjacent airbag units 12 are communicated through a communicating pipe 13 in the airbag distribution area, so that air chambers of the twenty-three airbag units 12 are communicated into a whole, and air pressures are uniform. At least one of the air bag units 12 is communicated with an inflatable ball 15 through an inflation tube 14, and the inflation tube 14 is provided with a deflation valve 16 for deflation. The air release valve 16 may be a conventional air release valve in the prior art, and will not be described in detail herein.

The cushion part 2 is arranged on the upper side of the airbag fixing cushion 11, when the hardness of the cushion is required to be increased, the airbag unit 12 is inflated through the inflatable ball 15, a one-way valve for preventing gas leakage is arranged at an air suction inlet of the inflatable ball (the prior art is used, and the description is omitted), and gas is inflated into each airbag unit 12 through the communicating pipe 13. When the hardness of cushion needs to be reduced, the air in the air bag unit 12 can be released through the air release valve 16, the softness and hardness of the cushion are determined by the air filling degree of the air bag unit 12, namely, the softness and hardness of the cushion can be simply adjusted through the operation of inflation and deflation, and the cushion is convenient to adjust and simple in structure.

Further, the air bag units 12 have a space therebetween, and the air circulation in the space can reduce the temperature of the seat cushion to some extent, thereby improving the comfort of use. Of course, in winter, the air bag units 12 can be deformed more, the space between adjacent air bag units 12 becomes smaller, and the air flow between the spaces of the air bag units 12 is reduced by appropriately reducing the amount of air in the air bag units 12, so that the heat preservation effect is improved to a certain extent.

In addition, because the position corresponding to the pre-sitting area is of a through hole structure, the air bag unit 12 lacks of support, the ventilation performance is improved, and the comfort is further improved.

In order to improve the air permeability of the seat cushion, in some preferred embodiments, the seat cushion portion 2 is provided with air holes 3 penetrating through the seat cushion portion 2.

In order to further improve the air permeability of the seat cushion, as shown in fig. 4 and 5, air holes 3 are formed at positions corresponding to the gaps between the airbag units 12 and penetrate through the seat cushion part 2 and the airbag fixing cushion 11 to form air flow passages penetrating through the seat cushion up and down, thereby increasing the air permeability of the seat cushion.

In order to ensure the supporting strength of the air bag unit 12 while maximizing the air flow of the seat cushion, in some preferred embodiments, referring to fig. 3, the air bag unit 12 has a cross-sectional area that gradually decreases from the end close to the air bag fixing pad 11 to the end away from the air bag fixing pad 11.
