[0050] Furthermore, first reserved grooves 91 are provided at positions of the first surface 11 corresponding to the respective hanging ears 24 , and the first reserved grooves 91 are used to expose the first connecting member 8 .

[0051] Please refer to Figure 3 As shown, the shape of the first reserved groove 91 is not limited, and the portion of the entire first connecting member 8 corresponding to the hanging ear 21 can be exposed. When the first reserved groove 91 is not present, the position of the first connecting member 8 can be judged by touch. By adding the first reserved groove 91 to expose the first connecting member 8, the accuracy of the fixing position of the fixing assembly is improved, and the air bag 2 is further prevented from falling off.

[0052] In a preferred embodiment, the fixing assembly further includes a C-shaped nail 71 , and the C-shaped nail 71 fixes the hanging ear 24 and the first connecting member 8 .

[0053] Please refer to Figure 4 As shown, after the C-shaped nail 71 passes through the hanging ear 24 at both ends to embrace the first connecting member 8 , the two ends of the C-shaped nail 71 are brought closer to each other, thereby fixing the hanging ear 24 and the first connecting member 8 .

After one end of the cable tie 72 passes through the first hanging hole 241 and then embraces the first connecting member 8, it passes over the top of the hanging ear 24 and is fixed to the other end of the cable tie 72, thereby achieving the fixation of the hanging ear 24 and the first connecting member 8.

[0056] Example 3

[0057] The similarities with Embodiment 1 and Embodiment 2 are not repeated here, and the difference lies in that: a second hanging hole is provided on the hanging ear 24; the fixing component is a buckle 73, and the buckle 73 passes through the second hanging hole to be fixedly connected to the first surface 11.

The buckle cap 731 can prevent the ear 24 from falling out. The outer wall of the buckle 73 is circumferentially provided with a plurality of barbs. Due to the characteristics of the foam 1, the barbs can be inserted into the foam 1 and fixed to the foam 1.

[0059] Furthermore, a second reserved groove 92 is provided at a position of the first surface 11 corresponding to the hanging ear 24 , and the buckle 73 fixes the hanging ear 24 in the second reserved groove 92 .

[0060] Please refer to Fig.11 and Fig.12 As shown, the opening direction of the second reserved groove 92 faces away from the second surface 12, and its shape is not limited, and only a certain depth is required, so that the buckle 73 can be embedded in the second reserved groove 92 and will not be exposed outside the first surface 11. Moreover, the buckle 73 is placed in the second reserved groove 92, and the force acting on the air bag 2 has a decomposition force along the first direction, which increases the pulling force on the air bag 2. However, the depth of the second reserved groove 92 is not easy to be too deep, so as to avoid the ear 24 not being long enough to stick to the bottom of the second reserved groove 92, thereby reducing the contact area between the ear 24 and the buckle 73.

[0061] Also, please refer to Fig.12 As shown, the buckle also includes a clamping base 74 and a clamping pin 741 used in conjunction with the clamping base 74.
