 
        1. Buffer protection : At the moment of collision, the airbag rapidly inflates and expands, forming a buffer zone that reduces the possibility of direct contact between passengers and hard objects inside the car (such as the steering wheel and dashboard), thereby reducing impact injuries to key areas such as the head and chest.
2. Disperse Impact Force : Safety airbags can disperse the impact force during collisions, and through their large surface contact, distribute the impact force to a wider area of the passenger's body, reducing the severity of local injuries.
3.Preventing secondary collisions : The rapid expansion of the airbag can also prevent secondary collisions between passengers inside the vehicle, that is, passengers throwing forward or backward due to the sudden stop of the vehicle and colliding with other parts or passengers inside the vehicle.
