In this airbag, the performance of protecting the occupant depends largely on the folding method of the airbag. Currently, the airbag is often rolled up from one edge to the inflation area, through which gas can flow into the airbag.

[0003] In the prior art, a patent with publication number CN1226860A discloses a method for folding an airbag of an airbag device, in which at least a portion of a flat fabric segment consisting of two fabric layers surrounding the airbag volume is folded inward by means of rolling, and the flat fabric segment is clamped by a tool approximately in the middle of its longitudinal length and rolled toward the gas generator, so that when the tool rotates toward the gas generator, the segments of the fabric segment on the side of the tool facing away from the gas generator are folded inward in the formed roll, that is, a two-layer roll of a folded airbag is formed, and the tool is pulled out of the roll at the end of the folding process.

[0004] The above structure utilizes the circular cross-sectional shape of the rolled airbag and requires a shell with a corresponding installation depth. It is impossible to obtain a flat airbag package according to the installation conditions of the seat airbag, resulting in the inability to position it between the vehicle body and the inner guard plate, and it does not match the area with a smaller installation depth and has poor adaptability.

The insert plates 16 in the positive folding plate 14 and the reverse folding plate 15 are extended out in turn for folding, so as to realize Z-folding on both sides of the SAB airbag, and then taken out after folding.

[0022] As an implementation method, Figure 1 , Figure 3 and Figure 4 As shown, the frame 13 is slidably mounted on the height-enhancing frame 5, and multiple groups of positive folding plates 14 and reverse folding plates 15 are provided.

[0023] Among them, the positive folding plate 14 and the reverse folding plate 15 both include a second cylinder 17, the second cylinder 17 is installed on one side of the frame 13, and the output end of the second cylinder 17 is connected to the plug-in plate 16, and the plug-in plate 16 in the positive folding plate 14 and the plug-in plate 16 in the reverse folding plate 15 are staggered.

[0024] In this embodiment, the left and right folding members 7 and 8 are moved toward the center at the same time, the inner insert plate 16 of the positive folding plate 14 of the first layer in the left folding member 7 is pushed out by the second cylinder 17, the air bag clamping plate 11 releases the air bag, and then the inner insert plate 16 of the reverse folding plate 15 of the first layer in the right folding member 8 is pushed out by the second cylinder 17, and the insert plates 16 in the positive folding plate 14 and the reverse folding plate 15 are extended out in turn to fold, so as to realize Z-folding on both sides of the SAB air bag.

[0025] As an implementation method, Figure 3 and Figure 4 As shown, a first cylinder 12 is installed on one side of the heightening frame 5 , and an output end of the first cylinder 12 is connected to an air bag pressing plate 11 , and the air bag pressing plate 11 is inserted between the positive folding plate 14 and the reverse folding plate 15 .
