understand how the airbag works in the car

There are various types of collision sensors that can be used, such as sensors placed on the front of the car (collision area), as well as an accelerometer placed inside the control module. The accelerometer measures the speed and severity of the collision. There is also a sensor placed on the door for side airbags.

When the sensor detects a collision, the sensor sends a signal to the control module which then ejects the airbag.

place in the airbag pairs.
Airbags mounted inside the dashboard or steering wheel can only be used in case of a collision on the front of the car. Similarly applies to airbags mounted on the side of the car. The airbag will come out when the car is hit at a certain angle. For example, the left airbag will not come out if there is a collision on the right and vice versa.

which controls airbags.
The control module is a small computer that receives accident data from different sensors, then decides which airbags to use. The module can not remove the airbag if it only receives one signal, the module needs two or more signals from the sensors to use airbags.

The second signal is given by the arming sensor located inside the car, which detects a sudden drop in speed. When the module control is sure that there is a severe collision, the module will send a signal to the squib inflater, also known as the igniter, which is an electrical device that has a thin bridge cable.

With the flow of electricity through the cable, the cable gets hot, which then burns airbag propellants made of sodium azide. Sodium azide is a fuel that can quickly burn and produce a lot of nitrogen gas. The nitrogen gas then flows through the filter and fills a nylon-made airbag.

how to work airbag
After your head hit a nitrogen-filled airbag, the airbag begins to deflate by releasing the gas through small holes. The smoke cloud that fills the vehicle is actually cornmeal or talcum powder, which is used to prevent sticky airbags from sticking together when folded inside.

The nitrogen released through the tiny holes is harmless (nitrogen is actually 78% of the air we breathe). You just need to open the door or window so that gas and smoke can come out.
difference airbag.
The side airbag system is different from the airbag system that lies ahead. The side airbags use a saving gas comprising a cylinder loaded with 3000-4000 psi compressed argon gas (compressed argon gas). The control module gives a signal to the igniter, which melts the small bladder inside the cylinder. The argon gas then fills the airbag. Just like nitrogen, argon is also harmless.

well that's the airbag system on the car that prioritizes safety and consumer comfort.
