How does the air bag supplemental restraint system work?

The air bag SRS is designed to

activate when the vehicle sustains

longitudinal deceleration sufficient

to cause the sensors to close an

electrical circuit that initiates air

bag inflation.

The fact that the air bags did not

inflate in a collision does not mean

that something is wrong with the

system. Rather, it means the forces

were not of the type sufficient to

cause activation. Front air bags are designed to inflate in frontal and

near-frontal collisions, not rollover, side-impact, or rear-impacts unless

the collision causes sufficient longitudinal deceleration.

The air bags inflate and deflate

rapidly upon activation. After air bag

deployment, it is normal to notice a

smoke-like, powdery residue or

smell the burnt propellant. This may

consist of cornstarch, talcum

powder (to lubricate the bag) or

sodium compounds (e.g., baking

soda) that result from the

combustion process that inflates the

air bag. Small amounts of sodium

hydroxide may be present which

may irritate the skin and eyes, but

none of the residue is toxic.

While the system is designed to help

reduce serious injuries, contact with

a deploying air bag may also cause abrasions, swelling or temporary

hearing loss. Because air bags must inflate rapidly and with considerable

force, there is the risk of death or serious injuries such as fractures,

facial and eye injuries or internal injuries, particularly to occupants who

are not properly restrained or are otherwise out of position at the time

of air bag deployment. Thus, it is extremely important that occupants be

properly restrained as far away from the air bag module as possible while

maintaining vehicle control.
