[0002] After the car seat airbag is connected to the shell, the airbag needs to be folded so that it can be stored in the shell. The flatness and size of the airbag during the folding process directly affect the accuracy of the airbag deployment path in the later stage, which has a crucial impact on the safety performance of the airbag. The traditional airbag folding method requires 2-3 people to cooperate, and the position of each folding line needs to be manually measured before each step of folding to complete the folding. Because the reference system is not fixed, the accuracy of the folding size is difficult to guarantee, and the efficiency is low.

[0003] The known Chinese public authorized invention (publication number: CN208698935U) discloses an airbag quick folding tool, which first puts the airbag shell into the airbag shell installation groove, then clamps the airbag shell collar into the airbag shell collar installation groove, fixes the airbag shell, then passes the airbag shell collar and lays it flat on the top surface of the tooling base, before folding the airbag, first locates the position of the folding plate through the size scale line on the side tooling assembly, then pulls the pull ring to move the clamping plate upward, and at the same time moves the folding plate spring fixing clamping piece to make the folding plate spring fixing clamping piece close to the folding plate, then releases the pull ring to make the clamping plate clamp the folding plate, and then manually folds the airbag, after the folding is completed, pulls the folding plate from the side to pull the folding plate out of the airbag, and the folding of the airbag is completed;

[0004] Although the above patent realizes the rapid folding of the airbag, manual operation of the folding plate is still required during the folding process, and the work efficiency is low. Therefore, a folding mechanism for a car seat airbag is proposed. Utility Model Content
