What are the impacts of replacing airbags in a car?
1 Answers
Replacing airbags has no impact on the car. However, if the airbags were deployed due to an accident, the impact on the car is significant, indicating that the vehicle experienced a very severe collision with substantial force. In such cases, the vehicle's frame may be damaged, and its safety performance could be greatly compromised. Even after repairs, the structural strength may not return to its original state. Additional Information: 1. Airbags: The airbag system is a passive safety protection system (see vehicle safety performance) that works in conjunction with seat belts to provide effective collision protection for occupants. In the event of a car collision, airbags can reduce head injuries by 25% and facial injuries by approximately 80%. 2. Working Principle: When a collision occurs during driving, the airbag sensor first receives the impact signal. If the impact reaches the specified intensity, the sensor activates and sends a signal to the electronic control unit (ECU). Upon receiving the signal, the ECU compares it with its stored data. If the conditions for airbag deployment are met, the drive circuit sends an activation signal to the gas generator in the airbag module. The gas generator ignites the gas-producing agent upon receiving the signal, generating a large volume of gas. This gas is filtered and cooled before entering the airbag, causing it to rapidly inflate through the padding in a very short time. The airbag forms an elastic cushion in front of the driver or passenger, then promptly deflates and contracts to absorb the impact energy, effectively protecting the head and chest from or reducing the severity of injuries.
