What does SRS mean in cars?

The SRS system refers to the airbag, directly translated into Chinese as: Supplemental Inflatable Restraint System, emphasizing the word 'supplemental'. It must be used in conjunction with seat belts to truly serve as a safety aid. The airbag system is a passive safety protection system. The working principle of the airbag: When a collision occurs while the car is in motion, 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 controller. Upon receiving the signal, the electronic controller 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, upon receiving the signal, ignites the gas-generating agent, producing a large amount of gas. This gas is filtered and cooled before entering the airbag, causing the airbag to rapidly inflate through the padding in an extremely short time. It forms an elastic cushion in front of the driver or passenger, then promptly deflates and contracts, absorbing the impact energy. This effectively protects the head and chest, preventing or reducing the severity of injuries. Precautions for airbags: It's essential to confirm whether the car can be retrofitted with additional airbags. Safety equipment should not be arbitrarily modified, as the stability and reliability of aftermarket airbags are certainly inferior to original equipment. The installation cost is also not cost-effective. Only the combined use of seats, headrests, seat belts, and airbags can most effectively protect passenger safety. Correct usage is the guarantee of safety.
