What is the SRS system in a car?

[OStella]

The SRS system in a car is the Supplemental Restraint System, which serves as an auxiliary device to the seat belt as an occupant restraint device. Composition of the SRS system: It consists of an integrated airbag module comprising the airbag and inflator mechanism, a collision sensor system that detects impacts and sends deployment signals to the airbag module, and wiring harnesses that transmit signals from the sensors. Types of airbags: Frontal airbags, divided into driver-side frontal airbags and passenger-side frontal airbags. Side airbags, generally available in two forms: one that protects only the occupant's chest and another that protects both the chest and head. Curtain airbags, which can be categorized into three types: those protecting only the front seats, those protecting both front and rear seats, and those protecting the front, rear, and third-row seats. Knee airbags, with the airbag module installed under the instrument panel. Smart airbags, equipped with additional Doppler speed sensors.
