Abstract

An airbag assembly includes: a gas generator that generates gas; a gas bag which expands due to the gas generated from the gas generator; an accommodating groove, wherein a safety air bag is arranged in the accommodating groove; a maintaining mechanism is arranged in the air bag and comprises a maintaining frame, the air bag is arranged between the maintaining frame and the containing groove, and the maintaining frame enables the outer wall of the air bag to be close to the inner wall of the containing groove. According to the safety air bag assembly and the automobile, the safety air bag assembly comprises the air bag, the containing groove, the air generator and the maintaining mechanism, the maintaining mechanism comprises the maintaining frame, the safety air bag assembly enlarges an opening of the air bag while guaranteeing the air guiding function of the maintaining ring, the area defined by fixing points of the air bag is large enough, and the safety air bag assembly is convenient to assemble and disassemble. After the air bag breaks through the instrument board, the air bag can be inflated all around, so that the unfolding stability of the air bag is improved; besides, the air bag passes through the space between the accommodating groove and the retaining mechanism, and the retaining ring can ensure that the air bag can be quickly far away from the air generator during inflation, so that the air bag is not easy to burn out.

Description

technical field [0001] The invention relates to the technical field of automobile safety, and in particular to an airbag assembly and an automobile. Background technique [0002] The airbag is installed closer to the front than the vehicle seat, and when the vehicle collides from the front, the airbag is inflated further forward than the passenger to protect the passenger by stopping the passenger from moving forward. [0003] In the prior art, the airbag assembly generally has two structures, one is the external hanging type, the airbag of this structure can ensure a larger inflation outlet, but the inflation is not integrated, and the blasting force is not enough, which makes the airbag not easy to open. Breaks through dashboard surface coverings. The other is a structure with a retaining ring to figure 1 For example, please refer to figure 1 , the assembly process of each part of the airbag device is as follows: [0004] 1. First insert the retaining ring 3 into the a...
