Research on the scientific principle involved in the inflation of an airbag. Explain how this device protects the driver and the front passenger from injuries.

Answer 1

An airbag is a vehicle safety device. It is an occupant restraint system consisting of a flexible fabric envelope or cushion designed to inflate rapidly during an automobile collision. Its purpose is to cushion occupants during a crash and provide protection to their bodies when they strike interior objects such as the steering wheel or a window.
Method for controlling inflation of an airbag in a vehicle which protects an occupant from injury in a crash involving the vehicle includes sensing a crash, inflating the airbag to protect the occupant during the crash, sensing contact between the airbag and the occupant during inflation of the airbag, and adjusting the continued inflation of the airbag after contact of the airbag with the occupant based on the sensed contact. Contact between the airbag and the occupant may be sensed in a variety of ways. One way is to arrange or otherwise incorporate a sensor in connection with the airbag to sense contact between the airbag and the occupant during inflation of the airbag, the continued inflation of the airbag after contact of the airbag with the occupant being adjusted based on contact between the airbag and the occupant as sensed by the sensor.
The airbag cushions the impact. This creates a small force over a long period of time rather than a big force over a small period of time, this is called and impulse. There is more force that comes from the airbag that it stops your body in time to not be thrown from the vehicle. It comes out with a high rate of energy.
