Specifically, the plurality of reinforcing ribs 12 are integrally formed, which not only enhances the overall stability of the structure around the air hole 11, but also makes the connection between the reinforcing rib 12 and the leather layer 1 more firm. Figure 1 Figure 2 As shown in the drawings, the plurality of reinforcing ribs 12 are arranged in a cross staggered manner and close to the opening direction of the air hole 11, so that when the air hole 11 is subjected to external force from different directions, the pressure can be dispersed and borne through the supporting points in multiple directions, effectively maintaining the shape and stability of the air hole 11.

[0041] As shown in the drawings, the plurality of reinforcing ribs 12 are arranged in a cross staggered manner and close to the opening direction of the air hole 11, so that when the air hole 11 is subjected to external force from different directions, the pressure can be dispersed and borne through the supporting points in multiple directions, effectively maintaining the shape and stability of the air hole 11. Figure 2 The cross section of the air hole 11 is square, and the four corners of the square are all circular arc transitions. This design not only enhances the structural stability of the air hole 11, but also reduces stress concentration and reduces the risk of tearing or damage of the air hole 11 at the corner, so that the air hole 11 is not easy to be stretched during use.
