Embodiment 1

[0017] see image 3 and Figure 4 , the airbag in the present invention includes an airbag 1 , an airbag housing 2 , a gas generator 3 and a circular snap ring 4 . Flanges 21 are evenly distributed around the bottom of the circular hole in the middle of the airbag housing 2, and the uniformly distributed flanges 21 form a cylindrical structure. In this example, the flanges 21 adopt square tooth pieces perpendicular to the bottom surface of the airbag housing.

[0018] Add a circle of connecting cloth at the bottom of the air bag 1, the bottom of the connecting cloth can be set as a tooth piece, and then set a hole 11 on each tooth piece of the connecting cloth, this hole is called "window" in this paper, the air bag 1 first Put into the air bag housing 2 from the top of the air bag housing 2, then the bottom of the connecting cloth can stretch out from the circular hole at the bottom of the air bag housing 2, and the windows set on the connecting cloth at the bottom of the ai...

Embodiment 2

[0021] see Figure 5 , it can be further improved on the basis of the above-mentioned embodiment 1, a flange 31 and a groove 32 can also be provided on the gas generator 3, that is, a gas generator 3 outer wall under the gas outlet hole of the gas generator 3 is provided with a Circle flange 31, set a circle groove 32 again on the gas generator outer wall under flange 31. The gas generator 3 is first placed under the connecting cloth of the air bag 1, and then the air bag 1 and the gas generator 3 are installed together from the top of the air bag housing 2, and the windows at the bottom of the air bag 1 are respectively hung on the corresponding windows at the bottom of the air bag housing 2. On the flange 21 , due to the existence of the flange 31 at this time, the flange 31 will rest on the bottom surface of the airbag housing 2 , and the groove 32 on the gas generator 3 corresponds to the flange 21 . Put the circular snap ring 4 from bottom to top into the cylindrical str...

Abstract

The invention relates to the technical field of machinery, particularly to a safety airbag. The safety airbag comprises an airbag, an airbag shell, a gas generator, a circular clamp ring, turned edges and a connecting cloth, wherein a circle of connecting cloth is connected at the bottom of the airbag, holes are uniformly distributed on the connecting cloth, the turned edges are uniformly distributed around the bottom of the circular hole in the middle of the airbag shell, and the uniformly distributed turned edges form a barrel-shaped structure; the airbag is arranged in the airbag shell, and after the connecting cloth arranged at the bottom of the airbag stretches out of the circular hole of the airbag shell, the holes on the connecting cloth are respectively sheathed on the corresponding turned edges on the bottom of the airbag shell; and the upper half part of the gas generator is located in the airbag shell below the airbag, the bottom of the gas generator is located below the turned edges after penetrating through the barrel-shaped structure formed from the turned edges, and the circular clamp ring is hooped outside the barrel-shaped structure formed from the turned edges. Compared with the prior art, the safety airbag has smaller part quantity, less weight and lower raw material cost; and the assembly procedures are simplified, the time of driving net is saved, and the assembly efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a safety airbag. Background technique [0002] Airbags are currently equipped in most motor vehicles. For the front airbags, namely the driver's airbag and the passenger's airbag, the pie-shaped gas generator has the advantages of compact structure, light weight, reliable performance, and low cost, and has been widely used at present. The airbags currently on the market, in order to connect the airbag shell and the pie-shaped gas generator, usually need to use multiple additional parts such as retaining rings, studs, nuts, etc., see the attached figure 1 And attached figure 2 . Such a design needs to be further improved in terms of product weight and manufacturing cost. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, by simplifying the connection structure between the pie-shaped gas generator and t...
