The two side edges S1, S2 of the first sheet body 10 of the present embodiment further form a plurality of segment portions 14, and the segment portions 14 are spaced apart between the recess portions 12. Referring to FIG. 2, the present embodiment is symmetrically joined except for the inner edge 121 of the recess 12, and further, the segment portions 14 of each side S1, S2 of the first sheet 10 are connected to each other side by side. In other words, after the recessed portions 12 of the first sheet 10 are symmetrically joined, the first sheet 10 has a rectangular shape and a size corresponding to the outer shape of the second sheet 20.

The arrangement of the accommodating area 13 may be a closed shape, and the first sheet body 10 is joined to the second sheet body 20 along the periphery of the lower circumference of the accommodating area 13 , thereby forming a plurality of The closed area is for receiving the accommodating area 13 of the elastic body 30.

In addition, the first sheet body 10 and the second sheet body 20 only indicate the sheet body located above and the sheet body below, and do not necessarily need to be separated. For example, the second sheet body 20 may be connected to the straight side S3 or S4 of the first sheet body 10 to be a one-piece type.

As shown in FIGS. 3 and 4, in the present embodiment, the accommodating area 13 is open for inflation inside, thereby adjusting the degree of elasticity of the air cushion. The outer edge 141 of the segment portions 14 of the first sheet body 10 is connected to the outer edge of the second sheet body 20 to form an outer connecting line L2. The first body 10 is openly joined to the second body 20 along the lower circumference of the accommodating area 13 to form a plurality of inner connecting lines L3, and the inner connecting line L3 of the lower periphery of each accommodating area 13 is U-shaped. Both the outer connecting line L2 and the inner connecting line L3 can be regarded as the second joint portion C2.
