Airbags for Safety System in Automobile Engineering

An airbag is automotive safety equipment which is used to save lives of the driver as well as the passengers inside a car during an accident. The purpose of an airbag is to cushion the occupants of the car at the moment of the accident in order to provide protection to their bodies when they strike an interior object such as steering wheel or window. The usage of airbag system lowers the intensity of injuries by reducing the force exerted by internal features like steering wheel, windows and dashboard. There are numerous researches going on in order to develop and evolve the features and efficacy of the airbags. Nevertheless the success of any safety equipment depends on its correct implementation and following the stated rules of usage. Airbags is significant safety equipment in the field of automobile and automobile engineering. This post states the importance of evolving an airbag in automobile and how one can pursue a course in automobile engineering.


An airbag is a vehicle occupant-restraint system using a bag designed to inflate rapidly and then quickly deflate during a collision. It consists of the airbag cushion which is a flexible fabric bag, an inflation module, and an impact sensor. As stated earlier, the purpose of the airbag is to provide the person inside the car both the driver and the passenger with a soft cushioning and restraint during a collision. It can reduce the degree of injury between the swinging affected occupant and the interior of the car. The airbag provides an energy-absorbing surface between the vehicle's occupants and the steering wheel, instrument panel, body pillar, headliner, and windshield. Although most cars generally contain two airbags for the two from seat occupants yet it really depends on the model of the car. There are vehicles which have up to 10 airbags and yet again there are car models which completely lack this feature.

Airbags are considered "passive" restraints and act as a supplement to "active" restraints. It is considered a "passive" device as no action by a vehicle occupant is required to activate or employ the airbag. On the other hand, seat belts are considered "active" devices because the onus of using this feature of the car is solely on the vehicle occupant. However the reason behind this naming is not related to active and passive safety, which respectively stands for systems designed to prevent collisions in the first place, and systems designed to minimize the effects of collisions once they occur. To ensure utmost safety, it is the first duty of both the driver and the passenger(s) to tie the seat belt around them after they get into the car. Even more important is for the car buyer to choose a well-equipped car model having at least 2 airbags specifically for the front seat equipments.


If someone is interested in knowing in detail about the mechanism of either airbags or any of the other interior or even exterior features of a vehicle, she has to opt for a course in automobile engineering. This post states basic information about airbags, an automotive safety equipment but a learner interested to know more about the technology of developing airbags or other related features of a vehicle can opt to do a Diploma in Automobile Engineering. George Telegraph Training Institute (GTTI) is a popular institution in Kolkata providing courses in various branches of engineering including automobile engineering. GTTI’s vast experience in vocational education has resulted in a standardised syllabi and methodology that is both structured and flexible to adapt to the changing needs of the industries.
