Background Info:
Airbags argon used required in all automobiles in all industrialized nations. Airbags were first invented by Walter Linderer in 1951. This early, primitive airbag was ground on a compressed air system in which air was stored under high pressure, and was then released into a bag to offend head injury during a collision. This system was non able to fill the airbag quickly enough to safely stop a drivers head from hitting the vagabond and/or the dashboard. Todays airbags are much more sophisticated with much faster vector sums. One of the simplest mechanisms that detect speedy effortal deceleration (as experienced during a frontal collision) is a ball that is held in place with a magnet. The ball is dislodged, and moves off due to inertia when the car decelerates rapidly. The ball then fits in a groove, and completes an electrical circuit that ignites sodium azide. This then causes a chain reaction creating N2 to fill the bag within 40 thousandths of a second. The magnet prevents the airbags from deploying for minor collisions, and bumps. The N2 that is produced fills nylon bags (stored at strategic locations) at velocities of 150 250 miles per hour.



The ideal airbag has already inflated, and has started to deflate by the epoch the driver/ passenger hits the bag. If the airbag is still inflating when the passenger hits the bag, then the passengers head would be thrown back by the force of the bag. This would cause extreme neck, and spine injuries causing any death, or paralysis. The wit would also be thrown from the front of the skull to the back with extreme force causing bruising of the brain that could result in a comatose state, or even death. If the passenger/driver hits the airbag after the bag finished inflating, nevertheless before the deflation process has started, then the high pressure of mess up inside the bag would make the bag very stiff. This would result in head trauma. If the person hits...If you want to get a full essay, order it on our website: Ordercustompaper.com
