Multiple first horizontal bars 1003 and first vertical bars 1004 are arranged in the middle of the first reinforcing layer 2, and multiple second horizontal bars 1103 and second vertical bars 1104 are arranged in the middle of the second reinforcing layer 4. In the present utility model, a first reinforcing layer 2 is arranged between the polyurethane cloth 1 and the rubber diaphragm layer 3, and a second reinforcing layer 4 is arranged between the rubber diaphragm layer 3 and the polyurethane cloth 5. The first reinforcing layer 2 generates tension and elasticity by means of the first horizontal bars 1003 and the first vertical bars 1004, and the second reinforcing layer 4 generates tension and elasticity by means of the second horizontal bars 1103 and the second vertical bars 1104, which can further increase the strength of the airbag cloth, has better elasticity than the multi-layer structure on the market, and has higher strength than the single-layer structure.

[0021] One side of the polyurethane cloth 1 is fixedly installed with the first reinforcing layer 2 through a first glue layer 6. Through the first glue layer 6, it is used for installing the polyurethane cloth 1 on the outer side of the first reinforcing layer 2.

[0022] The other side of the first reinforcing layer 2 is fixedly installed with the rubber diaphragm layer 3 through a second glue layer 7. Through the second glue layer 7, it is used for installing the first reinforcing layer 2 between the polyurethane cloth 1 and the rubber diaphragm layer 3.
