History of airbag development: airbag began to apply for patent from 1952, but it has gone through many twists and turns in application and promotion, and has gone through a long road of more than 30 years. Until 1984, after being abolished many times in the United States, the automobile collision safety standard was re-recognized and implemented. The standard stipulated that airbags should be equipped in front of the front seats of automobiles manufactured after 1 September 19951. Airbags were invented in America.

Airbag system is a passive safety protection system, which can provide effective collision protection for passengers when used in conjunction with seat belts. When a car collides, the car airbag can reduce the head injury rate by 25% and the face injury rate by about 80%.
