Airbags are safety systems currently equipped in most cars, and most cars are currently equipped with airbags. The working principle of airbag detonation is to instantaneously generate a large amount of gas through a gas generator to fill the airbag. However, during the detonation process, due to the high gas pressure generated by the gas generator, the sewing thread on the top of the airbag is prone to tearing, so that the airbag cannot achieve the protective effect; its solution is to fix it on the shell of the airbag through the first bracket plate and the second bracket plate, and be located inside the airbag of the airbag, and at least part of the gas generator is placed in the space between the first bracket plate and the second bracket plate, so that the gas generator is located below the second bracket plate provided with a plurality of diversion holes, so that the gas ejected instantly by the gas generator is effectively diverted, thereby reducing the instantaneous impact force on the airbag around the gas generator, and avoiding the tearing of the airbag sewing thread due to insufficient strength.

[0003] In the above scheme and the prior art, when the airbag generator bracket is in use, the generator bracket and the airbag housing are connected by bolts. During use, the bolts may be loosened by the gas ejected instantly from the gas generator, resulting in a gap between the generator bracket and the airbag, which cannot meet actual use requirements.
