Airbag
The airbag, or inflatable restraint system, or SRS(Supplemental Restraint System) is
a life safety device implanted in the front inside of the car. They can be found in the
steering wheel or the right dashboard. The inflated cloth bag stops the driver or the
passenger from hitting the dashboard, steering wheel, or the window.
The airbag system is made up of two major parts, the sensors and the bag. The
sensors under the hood react when the car is involved with a frontal collision of at least
12 ~ 15mph. That triggers an electrical signal that causes a chemical reaction in the
inflator module at the end of the bag. The cloth bag which is made out of a nylon is
inflated with a nitrogen gas which is safe, because the 80 percent of the air we breathe is
nitrogen gas, stops the crash victim from hitting the dash board or any other harmful
objects. Surprisingly, the entire inflation and deflation cycle takes less than 1/2 second.
Also, the speed of the airbag inflating is around 200 MPH.
According to the text book, the most frequent cause of death in collisions is injury to
the head and chest caused by hitting the steering assembly or windshield. However, air
bags help to prevent life threatening head and chest injuries. The NHTSA (National
Highway Traffic Safety Administration) reports airbags are 75 percent effective in
preventing serious head injuries and 66 percent effective in preventing chest injuries.
During this same time period, there were 87 deaths associated with airbags and 49 were
children. In most cases this was because the victim was too close to the airbag when it
started to deploy. Most of the children were improperly...
