How frontal air bags are useful, give some examples.
Advanced frontal airbags have been specifically designed for protecting the driver and the other occupants in a car, for any unfortunate frontal crash. The airbags have been designed to automatically determine the level of power that is needed for it to inflate and at what level. Sensors, used in such airbag system, provide the information of the rate of inflation. The sensors typically detect -
Ø The size of the occupant.
Ø Seating position.
Ø Use of the seat belt by the occupant.
Ø The severity of the crash.
It should always be remembered that airbags are supplementary safety systems, and you must use the seat belt as a primary condition of safety. The occupants in the car are required to sit in a proper position, with their seat belts on.
Every passenger in the car attains the same momentum of speed of that of the car when it is on the move. With a frontal crash the car comes to a sudden stop. At this time the force needed to stop the passengers in motion is quite large when the car’s momentum has suddenly come to zero. The frontal airbags help to bring the passengers’ motion to zero with minimum damage. The device sensors needs to act in fraction of a second, enabling the airbag to inflate.
