How Do Airbags Work?
by Novus AutoGlass Novus Auto GlassThere
is no denying the fact that airbags have made cars a lot safer. Ever since
their introduction in 1969 as ‘Air Pillows’, they have helped in bringing down
accident mortality rates to a bare minimum. However, recently the safety of
airbags has been questioned. This has lead people to wonder if these safety
devices can, in fact, be dangerous. We need to understand the internal working
of an airbag in order to answer this question.
The Science Behind Airbags
Airbags
aren’t that complex and the science behind them is quite simple. It is merely a
chain of events that is triggered when the car suddenly stops. It can be caused
either by hitting a tree or a pole or ramming into the back of another car.
Whatever the case, the accelerometer of the car notices this sudden drop in
speed and triggers a circuit which in turn sends an electric current through a
heating element. The heat created lights up a charge which is composed of
sodium azide pellets. This charge explodes and produces nitrogen gas which
inflates the nylon airbag that shoots out of the steering column. It takes only
a fraction of a second for this process to complete.
Benefits of Airbags
If the
airbags work as per their design, they can significantly reduce the injuries
sustained by car drivers and passengers in the event of an accident. The
airbags are designed to stop the body from hitting the steering column when the
car comes to a sudden halt. Not only does it soften the impact but also spread
it over a large part of the body. This ensures that the impact isn’t focused on
a single body part like the forehead or neck. Moreover, the airbags deflate
very quickly after successfully stopping the driver’s momentum to ensure that
their head doesn’t bounce off it.
Safety Concerns Regarding Airbags
The working
mechanism of the airbags is not flawed but the equipment itself can be
dangerous. For instance, if the airbags aren’t positioned correctly in the
steering column then they won’t be able to perform their job properly. In fact,
they would cause more harm than good if they aren’t deployed as they are
supposed to. Moreover, the airbags become a safety concern if your windscreen
is damaged. A cracked windscreen can weaken the car’s frame and its ability to
absorb sudden impacts. So, in order to ensure safety, you must get your Car
