DESCRIPTION

The purpose of an airbag is to reduce injury by either cushioning the occupants contact with the interior of the vehicle or preventing contact completely.

• An airbag is a large nylon bag which inflates and deflates very rapidly in the event of a severe crash.
• The driver’s airbag is housed in the centre pad of the steering wheel, and the passenger’s airbag, where fitted, in the upper left of the dash.
• Other airbags could also be found in the lower dash, seats, seatbelts, roof pillars and roof structures.
• Some motorcycles also have frontal airbags.

How airbags work

• The airbag’s deployment is controlled by sensors that detect the occurrence and severity of a crash. When the airbag controller determines that the airbag should be deployed, the system triggers an inflator unit that burns chemicals very rapidly to produce large volumes of inert gas to inflate the bag.
• As the bag inflates, it splits open the covers on the wheel / dash / pillar / seat etc, as it emerges.
• In the case of a front airbag, as the occupant’s head and upper body moves forward and strikes the inflated bag, the bag starts deflating through vent holes in its base to cushion the decelerating head’s forward movement.
• The whole process of inflating and deflating occurs within about 100 milliseconds - about the same time as the blink-of-an-eye. The process is so fast that the occupant is often unaware that the airbag has deployed.
• Side and curtain airbags are sometimes slightly slower to deflate as the types of crash they are designed to protect against are different to frontal impacts.
• In the process of deploying, considerable smoke, dust and noise is produced. This is normal.
