What is the reason why the airbag does not open when the car collides violently?

Mercedes-Benz S300 car traveled less than 6,543,800 kilometers, and suddenly the steering wheel was out of control at 87 kilometers of Hainan Middle Line Expressway (in Tunchang), causing the front and rear of the car to violently hit the guardrail, which was seriously damaged. Fortunately, the accident did not cause any casualties. The driver, Mr. Fu, said that after the vehicle violently hit the guardrail, the airbag in the car did not open, and it was suspected that there was something wrong with the quality of the Mercedes S300.

On the morning of July 16, Mr. Fu came to the Mercedes-Benz store to discuss. The 4S store said that the airbag of the car needs conditions to open, and it is not easy to open before reaching the impact point.

What happened:

At about noon on July 5th, 65438 12, the driver, Mr. Fu, and his colleagues drove the Mercedes S300 from Haikou and headed for Wuzhishan along the South Central Expressway. He said that at about 3 pm that day, the vehicle drove 87 kilometers to Hainan Middle Line Expressway (in Tunchang) and the steering wheel suddenly lost control. The vehicle hit the middle guardrail of the expressway at 90 degrees, and the vehicle rebounded from the middle guardrail to the emergency lane guardrail, and the speed dropped several times. He stepped on the brake and stopped to report to the insurance company. At present, the front and rear of the car have been smashed. Fortunately, there was no vehicle collision behind the incident, otherwise their lives would be hard to protect.

In response to the problems reflected by Mr. Fu, the driver of Mercedes-Benz S300, Auto Service Co., Ltd. said that the airbag of the vehicle will not be easily opened when it does not reach the impact point, because the airbag opening is a condition, the airbag sensor is an induction pulse, and the car is spinning at the time of the incident, and the ABS is locked, not out of control. The specific reasons need professional explanation.
