Learn About The Organization's Activities On Automobile Airbags

Design and operation

Airbag is fitted in the car only to be used only once, at the start of operation is also the time that it takes to ruin itself. Whether the front collision or side will activate a series of vehicle sensors include accelerometer sensor, crash sensor, pressure sensor slopes, brake pressure sensors, gyroscopes, sensor on the seat.

All these sensors are connected to the airbag controller ACU - particularly brain of the airbag system. When realize the timing of the operation of the airbag reasonable, ACU began activating the airbags inflate.

When compressed air systems used to inflate the airbag does not seem as effective as desired, engineers came up with the idea rather, they design inflate the airbag system based on the principle of missile work thick. Each airbag in combination with a "launcher" by electronic control system is located in a layer of a mixture of Sodium, Potassium Nitrate flammable. When activated the controller will make the compound on fire, burning will create a chemical reaction transformed into carbon compounds sodium, hydrogen, oxygen filled nylon airbag section.

Large amount of compressed gas in a small volume airbag deployment force from the steering wheel or the installation location other than the velocity of 320 km / h, the entire process takes place over a period of 0.04 seconds. This speed 5 times faster than the blink rate of the average human.

The final stage of the airbag after the bung is deflated, this process also takes place immediately after the process is completed inflated. The amount of gas will escape through the vents on the surface of the airbag, which also help victims avoid injury by the greater impact. One other effect of the collapse is the appearance of dust particles, which are mainly ... cornmeal and talcum powder lubrication effect airbags. Initially, the chemicals used in air bags are afraid affect human health, but today that doubts had disappeared, the current airbag system caused some slight irritation in the throat and eyes.

Set up

The first time the car side airbags and airbag shoulders are included in the list option in the form in 1995 Volvo 850. Three years later, the US federal government requires dual airbags fitted front protection protect two people sitting front row for all passenger cars line. By 2006, Honda was put airbags on motorcycles equipped.

On a car, the most popular is still the front airbags in the driver and passengers, on the steering wheel and dashboard. Airbags may inflate in a very small period of time to prevent passengers bumped into the details of the interior when the collision from the collision with the nature of moderate to severe. In the collisions the low-speed interface, advanced airbag systems provide different levels of protection by inflating the airbag with less pressure or not activated front airbags.

Type the second most common airbag is mounted side airbags car - side airbag (SAB) - obviously only works when there is a collision on the side of the vehicle body, while SAB will protect the head and shoulders to avoid injury. SAB has all three major categories: air bags protect the chest area, airbag head area and the last level is to combine the two regions protected. Traffic Safety Administration NHTSA Road America averaged about 60% of deaths in side collisions are caused by traumatic brain injury. When comparing the cars are not equipped with the vehicle SAB equipped, NHTSA estimates that each year as many as 976 lives saved if air bags slopes and 932 people will experience a serious accident if the missing bag a while ago.

In addition to front airbags and airbag ribs, several different types of airbags little known as a knee airbag that Mercedes-Benz SLR McLaren fitted to form the rear curtain airbags or be introduced in the form Toyota iQ in 2008 . in addition, Toyota also introduced the rear center airbag in 2009 to protect the passenger in case of encountering the vehicle side collision. On some modern cars are also equipped with air bags outside the windshield in order to save lives for people with a collision with a car.
