A plurality of ventilation holes 11 are located in the area enclosed by the plurality of grooves 12, the rear end of the ventilation hole 11 penetrates to the groove bottom of the groove 12, so that the ventilation hole 11 is communicated with the groove 12.

[0032] The sheet body 20 is used for covering the rear surface of the seat body 10, for example, is adhered to the rear surface of the seat body 10 by double-sided adhesive, after the sheet body 20 covers the groove 12, the groove 12 is limited to form the air duct 13, so that the airflow can flow along the air duct 13. The first interface 21 is arranged on the sheet body 20, the first interface 21 is communicated with the air duct 13, the second interface 31 on the shell of the fan 30 is communicated with the first interface 21 of the sheet body 20, so that the fan 30 can provide airflow into the air duct 13, the airflow flows along the air duct 13 and then blows to the occupant on the front side of the seat body 10 through the ventilation hole 11. In this way, the cooperation of the sheet body 20 and the groove 12 on the rear surface of the seat body 10 can continuously provide airflow for the ventilation hole 11 in the seat body 10, thus the cooperation structure of the sheet body 20 and the groove 12 is equivalent to the function of the air bag in the prior art, but the cooperation structure almost does not occupy the space on the rear side of the seat body 10, and the manufacturing cost is also low.

[0033] The leaf spring 50 is located on the rear side of the sheet body 20, the main function of the leaf spring 50 is to support the seat body 10, in the utility model, the positioning groove 51 is arranged in the region corresponding to the first interface 21 of the leaf spring 50, the docking part 32 is arranged on the shell of the fan 30, the shape of the docking part 32 matches the shape of the positioning groove 51, the second interface 31 is formed in the inside of the docking part 32, when the fan 30 is installed, the docking part 32 passes through the positioning groove 51 and is inserted into the first interface 21, so that the second interface 31 is communicated with the first interface 21, the positioning groove 51 limits the radial movement of the docking part 32, then the circumferentially arranged bolts are threaded through the shell of the fan 30 and are screwed into the leaf spring 50 to mechanically fix the fan 30 and the leaf spring 50. In this way, the fan 30 is mechanically fixed with the leaf spring 50 to limit the shaking of the fan 30, and the airflow provided by the fan 30 can enter the air duct 13 by communicating the first interface 21 and the second interface 31.

[0034] In some preferred embodiments, the front side surface of the sheet 20 is configured with a support strip 40 in the area corresponding to the groove 12 of the rear surface of the seat body 10, the support strip 40 matching the extension track of the groove 12, the width of the support strip 40 being greater than the width of the groove 12 so that the edges on the width of the support strip 40 can lap on both sides of the groove 12. The rigidity of the support strip 40 is greater than the rigidity of the sheet 20, and the support strip 40 is used to inhibit the corresponding area of the wind bag from collapsing automatically or due to pressure, thereby ensuring the smoothness of the air duct 13.
