Airbag systems are made up of three basic components the bag itself, the inflator unit, and the crash sensor. The bag and inflator are housed together in an airbag module. In most cases, the sensor is located in the passenger compartment facing upwards, so in the event of an accident it is detected immediately.
When the crash sensor deteriorates rapidly, it causes the inflator to produce nitrogen gas as quickly as it raises the bag, causing the bag to escape its condition. The most commonly used type of sensor is the electromechanical ball and tube structure. This type of sensor is made of a tube with a rotating machine and a metal ball on one of them held in place by a magnetic field. In the event of a strong enough blow, the ball is removed from its place, pulling down the tube and hitting the switch. Blowing the switch causes the electrical circulation that overflows the airbag to close. With the circuit closed, the inflator inserts to install an airbag.
Inside the inflation device is a small, solid propellant that is completely different from the types of antagonists used in rocket boosters. The propellant used in most airbags is a combination of sodium azide (NaN3) and potassium nitrate (KNO3). When these two chemical compounds react, they heat up rapidly and produce the nitrogen gas that fills the bag.
Airbags should send a very high speed to properly protect car occupants from hitting the interior of the car. In fact, when the airbag throws off its module it reaches 322km / h. The whole process of airbag bottles rises from the time the accident is discovered when the bag is completely above holds about one twenty five seconds. Seconds after the bag has completely risen, the gas inside the bag begins to slowly leak from the small holes. This allows people inside the car to have a room after the accident. In addition, after an airbag pulls on people around it they may notice that a toxic substance has been released. This material either talcum powder or corn starch is harmless and is used to keep air layers soft while stored in the module.
Can air layers cause damage?
Airbags should strike a balance between speeding fast enough to prevent occupants from colliding with the inside of the vehicle and robbing at high speed which results in injuries. To protect the occupants of the vehicles, the airbags must be tightened immediately so that under certain conditions the force of the inflation itself could cause injury to the occupants of the vehicles. Therefore, drivers and passengers in the front seat should take care to ensure that they are not placed in a position that could put them at risk of injury in the event of an airbag deploy.
The position of the driver in relation to the airbag is a very important factor in whether you are injured in the air bag service. Transportation Canada notes that the only equivalent of eight people in 2001 who suffered injuries caused by airbags was that they were too close to the air bag while operating
