[0006] As a preferred embodiment of the present invention, the airbag guide cloth is connected and fixed to the main seat cover by sewing, and the airbag reinforcement cloth is connected and fixed to the side seat cover by sewing.

[0007] As a preferred embodiment of the present invention, the airbag reinforcement cloth is connected and fixed to the elastic drawstring and the clamping strip by sewing, and the elastic drawstring is connected and fixed to the seat side guard by sewing.

[0008] As a preferred embodiment of the present invention, there are at least three elastic straps, and the three elastic straps are arranged at intervals along the length direction of the seat back.

[0009] As a preferred embodiment of the present invention, the sewing line between the airbag reinforcement cloth and the seat side protector just coincides with the airbag line.

[0010] Advantages and beneficial effects of the utility model: The airbag fixing structure provided by the utility model comprehensively considers the cost, labor and feasibility, and finally adds an airbag reinforcement cloth piece on the outside of the guide cloth. The airbag reinforcement cloth is arranged on the inner side of the seat side guard. One end of the airbag reinforcement cloth is fixed to the side of the seat side guard close to the airbag line, and the other end is connected to the elastic drawstring and the clip strip. The seat side guard and the airbag reinforcement cloth are fixed to the back of the seat frame through the clip strip, so as to constrain the deployment position of the airbag cloth, reduce skin tearing, and improve blasting stability and experimental success rate.
