Airbags - Latest Advancement in Car Safety Technologies

Airbags are one of the most advanced car safety technologies that have revolutionized the car industry in the recent years. These are flexible and inflatable cushions built into the car interiors mainly on the steering wheel or the dashboard designed in a way to rapidly expand in case of a car accident. Earlier these were only fitted on the steering wheel but with further advancements airbags are now also found on the door interior, roof, and under the car seat.
Airbags works on a crash testing technology that enables the installed sensor to detect an accident. These sensors further send an electric current to a wire that heats up and charges the inflator. Charging of the inflator undergoes a chemical reaction to fill create gas and inflate the flexible cushions positioned on the steering wheel or the dash or rear compartment in case of side-impact airbags. As the gas expands and fully inflates the airbag it starts deflating, thereby cushioning the impact.
The primary function of airbags is to reduce injuries in case of a car accident. This function follows laws of motion that states that all moving objects have speed and impetus.
