How do Airbags Work? - airbag

The airbag is a clever invention.
If there is an accident, they will protect the people traveling by car.
Do you know what made them come out of the accident to save your head?
The answer is that we are about to post in this WheelZine.
There are many technical names for airbags, such as supplementary restraint systems (SRS), Air Cushion Restraint Systems (ACRS), and supplementary inflation constraints (SIR ).
Airbags are one of the safety features in the car that can protect you when an accident occurs.
Use airbags to protect the head, neck and chest.
For the safety of drivers and passengers, they are repaired by the vehicle manufacturer.
Typically, they appear from the steering wheel or dashboard within a few milliseconds of the collision.
When your head hits the airbag, the bag starts to deflate slowly and get you off the bus.
In some cars, when the speed is over 200,
300 miles/hour, the airbag will automatically deploy even if there is no collision.
If you don't wear a seat, the airbag will usually prove not enoughbelt.
Due to the increase in the number of accidents, the governments of many countries have used seats
Seat belts are mandatory and are said to have effectively reduced the number of injuries due to vehicle accidents.
However, the latest design of the airbag can protect people, even if he does not wear a seatbelt.
There is a common misconception that airbags prevent our bodies from being thrown forward after a collision.
They are actually meant to protect the driver's head and prevent it from hitting the steering wheel. It is the seat-
Even after the collision, the seat belt will keep the driver in the seat. If the seat-
Seat belts and airbags work together and they can completely eliminate the possibility of injury even in a serious car accident.
When a collision sensor in the car detects a collision, it sends a signal to the control module that deploys the airbag.
There are various types of collision sensors, such as Old sensors placed in the front of the car (collision zone), and the latest micro-mechanical accelerometer installed inside the control module or the airbag brain.
The micro-mechanical accelerometer actually measures the speed and severity of the collision.
Sensors for deploying side airbags are also placed inside the doors.
Front and side sensors only work with front and side airbags, respectively.
Airbags installed on the dashboard or steering wheel will only be opened if there are airbags in front
End the collision, for example in the case of a head collision
In a collision, or within 30 degrees from any side of the car's core.
The same rule applies to airbags installed on the side of the car.
When the car hits at a certain angle, the airbag is unfolded.
If the collision is on the right side, the left side will not be deployed and vice versa.
The control module or airbag brain is a small computer that receives collision data from different sensors and then decides which airbag to deploy.
If the airbag receives only one pulse, it cannot expand the airbag.
Doing so requires two or more pulses from the sensor.
The second pulse comes from the armed sensor located inside the vehicle, which senses a sudden drop in speed.
When the control module determines that a serious collision occurs, it signals the squib inflator (also known as the ignition), an electrical device with a fine bridge line.
When the current flows through the wire, it overheat and ignites the airbag propellant made of sodium bicarbonate.
Sodium nitrate is a fast
Burn fuel that produces a large amount of nitrogen that fills the nylon airbag through a filter.
When your head hits nitrogen
Filled bags, the bags release gas through small holes.
The smoke that fills the vehicle is actually a talcum powder or corn starch.
When the bag is folded inside, the powder prevents the bag from sticking to itself.
Nitrogen released from small holes is absolutely harmless (nitrogen actually accounts for 78% of the air we breathe in ).
All you need to do is open the door or window and the gas and powder can escape.
The side airbag system is different from the front airbag system.
It uses storage
Gas inflator, equipped with a 3000-
Compressed gas of 4000 psi.
The control module signals the ignition, which melts a small bladder inside the cylinder.
Argon gas then fills the airbag and helps inflate.
Like nitrogen, ar is harmless.
Make sure it has an airbag system if you plan to buy a car.
Use of seats-
Around the world, the damage caused by seat belts and airbags in car accidents has been greatly reduced.
