When your car, truck, SUV or van is involved in an accident, the airbag sensors are the first components to detect the crash. To get more information about takata airbag lawyer you may head to http://takataairbagrecalllawsuit.com/takata-airbag-lawyers.asp.
In vehicles, these detectors were as the vehicle slowed down during the crash switches that reacted to changes in speed. Once two detectors "closed" to affirm that a crash was happening, electric current was allowed to flow into the air bag modules.
In newer vehicles, electronic sensors measure the deceleration (negative acceleration) of the automobile, process it mathematically via a computer algorithm, and compare the measured values to the values stored within it from crash testing. If the values indicate that the collision is intense than the crash tests that are saved, the controller module will allow current to flow into the airbag modules.
When the electric current is flowing into the airbag modules, it warms up a "squib" inside the inflator which has a small filament within a container of explosive or flammable substance. The compounds start to burn when the filament gets hot enough.
These burning sets a reaction of a compound called sodium azide inside the inflated, which produces nitrogen gas, together with byproducts that are many of. In some vehicles, the sodium azide inflator has been replaced with an inflated using gas a mix of argon and helium.
Since the airbag fills, it increases in size, finally breaking out from behind its cover, and inflating to its size. Driver airbags are shaped like a round pancake larger and are about 12 to 20 inches thick when stuffed.
