The function of an airbag is to help the passenger in the vehicle reduce their rate in collision without gaining injured. Objects in a automobile have mass, speed and also direction. If the object, such together a person, is not secured in the car they will proceed moving in the same direction (forward) through the exact same speed (the speed the car was going) once the car abrubtly stops until a force acts upon them. Every object has actually momentum.Momentum is the product of a passenger"s mass and velocity( rate with a direction).In order to protect against the passenger"s momentum they have to be plot on by a force. In some situations the passenger hits right into the dashboard or windshield i m sorry acts as a force stopping them however injuring them at the same time. an airbag gives a pressure over time. This is recognized as impulse. The an ext time the pressure has come act on the passenger to slow-moving them down, the less damage caused to the passenger.

There is a minimal amount the time the the airbag needs to act between when the car hits the other object and also the passenger access time the steering wheel. around 15 come 20 milliseconds after the collision occurs the crash sensors decision whether or not the collison is serious enough to inflate the airbag (usually 6 - 10 km/h). If the crash sensors decide to inflate the airbag it will certainly be deflated at about 25 milliseconds after the crash. the takes about 20 millisecond to inflate the airbag because that the human to land into. around 60 milliseconds the person has made contact with the airbag and the airbag now starts to deflate. The passenger continues to be acted on by the airbag together it is in the deflation procedure which takes about 35 to 40 milliseconds. that is still vital to undertake a seatbelt although every automoblies should be equiped with an airbag because of a couple of reasons: 1) The crash sensors carry out not signal for the airbag to inflate uneven the vechile is relocating atleast 6 km/h. Damage can still happen to the passenger if the collision is the a slower speed. This is to be the seatbelt plays vital role. 2) The airbag situated in the steering wheel walk not assist the passenger in a collision where one more car hits them side on. 3) once the automobile the passenger is in is backing up and collides the the rear end with one more object the airbag does not help. through today"s technology other airbags are being presented in addition to the steering wheel airbag and also the passenger airbag.
