[0009] In some embodiments, the edge of the first opening of the airbag is bent outward to form a first flange, and the outer edge of the first plate is bent inward to form a first hook, and the first hook is snap-connected to the first flange.

[0010] In some embodiments, the foot assembly further includes a second bolt;

[0011] The second end sealing plate includes a second plate body and a second recessed portion connected to the second plate body, the second recessed portion extends toward the interior of the airbag, an inner surface of the second recessed portion is provided with an internal thread, and the second bolt is connected to the second recessed portion by threads.

[0012] In some embodiments, the edge of the second opening of the airbag bends outward to form a second flanging, and the outer edge of the second plate body bends inward to form a second hook, and the second hook is snap-connected with the second flanging.

[0013] In some embodiments, both the airbag and the base are made of rubber, and the hardness of the rubber material of the base is greater than that of the rubber material of the airbag; and / or
