[0075] The orthographic projection of the crotch breathable outer hole 211 on the crotch inner protective layer 11 is cross-arranged with the crotch breathable inner hole 111, that is, the orthographic projection of the crotch breathable outer hole 211 on the crotch inner protective layer 11 overlaps with the crotch breathable inner hole 111, so as to ensure that the seat body has better breathability in the crotch, and foreign matter can only penetrate into the seat body through the part where the orthographic projection of the crotch breathable outer hole 211 on the crotch inner protective layer 11 overlaps with the crotch breathable inner hole 111.

[0076] In the embodiment of the present application, there is no limitation on the communication method between the crotch ventilation outer hole 211 and the crotch ventilation inner hole 111. In the present application, air needs to reach the outside of the seat body from the outside of the seat body, and the air flow will naturally pass through the crotch ventilation outer hole 211 and the crotch ventilation inner hole 111 to realize air circulation between the inside and outside of the seat body.

[0077] Please refer to Figure 2 and Figure 3 As shown, in some embodiments of the present application, the crotch ventilation outer hole 211 and the crotch ventilation inner hole 111 are both set as long holes, and the length direction of the crotch ventilation outer hole 211 is set at an angle to the length direction of the crotch ventilation inner hole 111.

[0078] The embodiment of the present application does not limit the length of the crotch ventilation outer hole 211 and the crotch ventilation inner hole 111. At the same time, the embodiment of the present application does not limit the size of the angle between the length direction of the crotch ventilation outer hole 211 and the length direction of the crotch ventilation inner hole 111. As long as the crotch ventilation outer hole 211 and the crotch ventilation inner hole 111 can reduce the probability of foreign matter passing through the crotch ventilation outer hole 211 and the crotch ventilation inner hole 111 to the inner side of the seat body while ensuring the ventilation of the crotch of the seat body, it is sufficient. In order to further reduce the probability of foreign matter passing through the crotch ventilation outer hole 211 and the crotch ventilation inner hole 111 to the inner side of the seat body, in some embodiments of the present application, the length direction of the crotch ventilation outer hole 211 and the length direction of the crotch ventilation inner hole 111 are set at a 90° angle, so that the overlapping area of ​​the orthographic projection of the crotch ventilation outer hole 211 on the crotch inner protective layer 11 and the crotch ventilation inner hole 111 is minimized. For details, please refer to Figure 2 and Figure 3As shown, the length direction of the crotch ventilation outer hole 211 is parallel to the length direction of the crotch outer protective layer 21 , and the length direction of the crotch ventilation inner hole 111 is parallel to the height direction of the crotch outer protective layer 21 .
