[0002] Airbags are a type of passive safety device used in cars and other vehicles, designed to protect passengers from serious injuries in the event of a collision. Airbags are usually located on the steering wheel, dashboard, seat edge, etc. of the vehicle. When a vehicle collides and the airbag system is triggered, the airbag will quickly inflate and pop out to form a protective barrier, helping to mitigate the impact force of the passengers in the collision and reduce the possibility of head and chest injuries. Airbags play an important role in vehicle collision accidents, effectively reducing the degree of injury and protecting the lives and health of passengers. In order to facilitate the storage and transportation of airbags, airbag folding devices are often used to fold the airbags from the deployed state to a smaller size.

In addition, there is a risk of human error in the traditional manual folding process, which can easily lead to inaccurate folding of the airbag. In order to solve the above problems, the present application proposes a folding mechanism for an airbag. Utility Model Content

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] 1. The device completes the folding operation of the airbag by setting a folding structure. The airbag to be folded is laid flat on the top of two folding plates and a processing box, and then the motor is started to drive the disc to rotate, thereby driving the protruding column to perform a circular motion in the movable groove, thereby driving the incomplete gear to swing back and forth. With the help of the cooperation between the incomplete gear and the connecting rack, the slide plate and the two active racks are driven to move back and forth left and right.
