Abstract
The
present topic is
about safety airbags
in cars. No safety device
has consumed more
attention and resources
than the airbag. It
is known with
high confidence that
when a crash ours , the
presence of airbag
reduces fatality risk
to drivers.
Introduction
Air
Bags have been under development for many years. The attraction of a soft
pillow to land against in a crash must be very strong – the first patent on an
inflatable crash-landing device for airplanes was filed during World War
II. In the 1980’s the first commercial
air bags appeared in automobiles. Since 1988, all new cars have been required
to have air bags on both driver and passenger sides .To date, Statistics show
that air bags reduce the risk of dying in a direct frontal crash by 30
percent. Newer than steering Wheel
mounted or Dashboard-mounted bags, but not so widely used, are seat-mounted and
door mounted side air-bags. Some experts
say that within the nest few years, our cars will go from having dual air bags
top having six or even eight air bags.
Main Parts Of
Air Bag
There
are three parts to an air bag that help to accomplish this feat:
vBag
v Sensor
v Inflation system
Working Of Air Bags
Air
Bags are designed to inflate in frontal or frontal-angle impacts in which the
car strikes an immovable object at more than about 16 Kilometers per hour or
another car at twice that speed. After a
collision, sensors sense an electric current to an igniter system or, in some
cases, to the computerized control unit.
This unit evaluates the situation and then sends an electrical impulse
to the igniter system. The electric current
heats a filament (wire), which then ignites a capsule………
Conclusion
The
air bags are of greater importance in today’s vehicles since safety of human
life is of prior importance. Since the
count of automobiles is increasing tremendously on our roads, the probability
of accidents is also more. So far a safe
riding and for saving the precious life the safety bags must be
implemented.
Disarming The Airbag
Steps in disarming
• Disconnect the battery
• Wait 30 seconds. The air Bag is equipped with a capacitor and
it’s important to make sure that it is completely discharges before
continuing. Change the oil while waiting

airbag assembly, the retainer attached to the steering wheel, the steering
wheel and the clock spring.
