What Makes an Airbag Inﬂate?

In a deployment event, the sensing system sends

an electrical signal triggering a release of gas from

the inﬂator. Gas from the inﬂator ﬁlls the airbag causing

the bag to break out of the cover and deploy. The

inﬂator, the airbag, and related hardware are all part

of the airbag module.

Frontal airbag modules are located inside the

steering wheel and instrument panel. For vehicles

with seat-mounted side impact airbags, there are airbag

modules in the side of the front seatbacks closest to the

door. For vehicles with roof-rail airbags, there are airbag

modules in the ceiling of the vehicle, near the side

windows that have occupant seating positions.

How Does an Airbag Restrain?

In moderate to severe frontal or near frontal collisions,

even belted occupants can contact the steering wheel

or the instrument panel. In moderate to severe side

collisions, even belted occupants can contact the

inside of the vehicle.

Airbags supplement the protection provided by

safety belts.

Frontal airbags distribute the force of the impact more

evenly over the occupant’s upper body, stopping the

occupant more gradually. Seat-mounted side impact and

roof-rail airbags distribute the force of the impact more

evenly over the occupant’s upper body.

Rollover capable roof-rail airbags are designed to

help contain the head and chest of occupants in the

outboard seating positions in the ﬁrst, second, and

third rows. The rollover capable roof-rail airbags

are designed to help reduce the risk of full or partial

ejection in rollover events, although no system can

prevent all such ejections.

But airbags would not help in many types of collisions,

primarily because the occupant’s motion is not toward

those airbags. See When Should an Airbag Inﬂate? on

page 1-65 for more information.

Airbags should never be regarded as anything more

than a supplement to safety belts.
