Preferably, the outer bag 2 is made of a composite material and the inner bag 1 is made of a single material. Compared with a single material, the composite material has the advantages of higher supporting strength and difficult deformation and burst; compared with a composite material, the single material has the advantages of simple welding and longer service life. Therefore, the outer air bag 2 is made of a composite material, and the inner air bag 1 is made of a single material, so that the nested structure air bag body has the advantages of high supporting strength and long service life.

Specifically, the composite material can be formed by a TPU or PU composite fiber fabric lining, and the single material is a TPU or PU material.

Preferably, the composite material is a double-layer composite structure of a TPU layer and a nylon layer, or a three-layer composite structure of the TPU layer, the nylon layer and the TPU layer. Wherein the wear-resistant grade can be improved by arranging the nylon layer.
