Seats and Restraints 3-27

In any particular crash, no one can

say whether an airbag should have

inflated simply because of the

damage to a vehicle or because

of what the repair costs were.

For frontal airbags, inflation is

determined by what the vehicle hits,

the angle of the impact, and how

quickly the vehicle slows down.

For seat‐mounted side impact and

roof-rail airbags, deployment is

determined by the location and

severity of the side impact. In a

rollover event, roof-rail airbag

deployment is determined by the

direction of the roll.

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 airbags 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 and second 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 3‑25 for more information.

Airbags should never be regarded

as anything more than a supplement

to safety belts.
