Frontal Air Bags
- During moderate to severe frontal crashes, frontal air bags
inflate to prevent occupants from hitting the interior of the
vehicle.
- Frontal air bags do not eliminate the need for safety belts.
- Occupants who are unbelted or out of position can be seriously
injured or killed if they are too close to the air bag module when
it deploys.
- Frontal air bags typically do not offer protection in
rollovers, side-impact or rear-end crashes.
- Frontal air bags, either 1st or 2nd generation, also known as
"depowered" air bags, have been standard equipment in all
passenger cars since model year 1998 and all SUVs, pickup trucks
and vans since model year 1999.
- Advanced frontal air bags, or 3rd generation, are being phased
into new model year 2004 vehicles. All light vehicles will have
advanced frontal air bags by model year 2007.
Side-impact Air Bags (SAB)
- Side air bags (SABs) are inflatable devices that are
designed to help protect your head and/or chest in the event of
a serious crash involving the side of your vehicle. There are
three main types of SABs: chest (or torso) SABs, head SABs and
head/chest combination (or “combo”) SABs.
- Chest (or torso) SABs are mounted in the side of the seat or
in the door and are designed to help protect an adult’s chest in
a serious side-impact crash.
- Head SABs are usually mounted in the roof rail above the
side windows and are designed to help protect an adult’s head in
a side-impact crash. There are two types of head SABs: curtain
SABs and tubular SABs. Typically, curtain SABs help protect both
front and rear occupants in a side-impact crash; some may also
provide protection from ejection if your car rolls over after
being struck on the side.
- Head/chest combination (“combo”) SABs are usually mounted in
the side of the seat and are typically larger than chest (or
torso) SABs. Combo SABs are designed to help protect both the
head and chest of an adult.
- How they work: SABs inflate in a fraction of a second and
are designed to help keep your head and/or chest from being hit
by hard objects both inside and outside your vehicle in serious
side-impact crashes. Sensors determine whether a crash is severe
enough to inflate the SABs. Unlike frontal air bags, some of the
side curtain air bags may stay inflated for several seconds
during a crash for additional protection in the event of a
rollover.
- Vehicle can be equipped with both front and side air bags.
Frontal air bags have been standard equipment in all passenger
cars since model year 1998 and all SUV’s, pickups and vans since
model year 1999. SABs are being offered as standard or optional
equipment on many new passenger vehicles.
Air Bag Safety
Airbags are fitted to cars to protect the driver and
in some cases the front-seat passenger during frontal and
front-angled collisions.
Airbags are most effective when used in conjunction with seatbelts,
and are designed to reduce injuries to the upper body and face by
helping to stop you being thrown against the windscreen, steering
wheel and other hard surfaces during an accident. However, they
don't protect you in roll-over, rear, side or low-speed collisions,
although some car manufacturers, such as Volvo, are fitting
side-impact airbag systems to some of their models.
Not all accidents are severe enough to trigger an airbag.
This is just as well, since the seatbelt should provide adequate
protection in low-speed collisions, and replacing your airbag can be
expensive. Airbag systems for the Australian market tend to be
designed to act in higher-speed accidents than those made for the US
market, where seatbelt usage is much lower than in Australia.
Airbags can cause injury
Airbags inflate in a fraction of a second and with great force.
This means that if the front-seat occupants of the car are not
properly seated and strapped in with seatbelts or are obstructing an
airbag compartment with part of their body, they may be injured.
There have been reports in the US of children sitting in the front
seat or lying in a rear-facing child restraint mounted in the front
seat being crushed to death by airbags in low-speed accidents, which
they might have otherwise survived.
According to the NSW Roads and Traffic Authority, it is common
practice to carry small children in the front seat in the US and
Europe. In Australia they're generally in the back because our child
restraints usually can't be fitted in the front seat. As long as
this doesn't change we shouldn't have the same problem with children
being injured, they say.
However, Australian adults still need to be cautious - there have
been reports in the US of airbags causing bruises, broken arms, eye
damage and adult fatalities.
But they do save lives Despite the occasional problems, airbags
in most cases do prevent serious injury and save lives. For example,
General Motors Holden says there has been a 'dramatic' reduction in
facial, head and chest injuries to occupants of airbag-equipped
Commodores involved in accidents.
The US-based Insurance Institute for Highway Safety has also
compared driver deaths in airbag-equipped cars to cars without
airbags. The research found there were 23% fewer deaths in
airbag-equipped cars involved in frontal and front-angled crashes.
There are ways to make your airbag as safe as possible:
Airbags are a secondary safety device, which means they’re
designed to reduce injuries once a crash is happening. (Primary
safety devices, such as brakes, steering and anti-lock braking, are
designed to help you avoid having an accident in the first place -
obviously a preferable option.)
While airbags can sometimes cause injury, they do save lives, and
there are ways of minimising the risk of injury.
General safety
- All occupants of the car should wear a seatbelt, irrespective
of whether the car is fitted with airbags.
- Avoid sitting too close to the airbag compartment, and don’t
obstruct it with any part of your body. Airbags inflate with great
force and could seriously injure you if you sit too close. This
means drivers shouldn’t hunch over the steering wheel, and
passengers shouldn’t lean or put their feet up on the dashboard.
- Don’t cover the airbag compartment or place any objects
between you and the airbag, including dashboard covers.
- Any maintenance or repair work on the electrical system,
steering column, dashboard area, steering wheel or airbag system
are best carried out by an authorised repair person. If you’re a
‘do- it - yourselfer contact the manufacturer to find out
whether you need to disable the airbag in order to carry out
repairs -- though if you’re not competent with airbags, the best
advice is don’t touch them.
- Fitting a bullbar or making some other modification to the
front of the car could change the impact speed which triggers the
airbag, reducing its effectiveness - check with the manufacturer
before doing so.
- If you’re in a low-speed accident, don’t be surprised if the
airbag doesn’t go off. In most cases it simply means the accident
wasn’t serious enough for the airbag to deploy.
Children and airbags
- Children should sit in the back set of a car and use a
seatbelt or child restraint. Where the front seat has to be used,
it should be moved as far back as possible from the airbag.
- Never fit a rear-facing child restraint to the front passenger
seat. In fact, it’s always better to install a child restraint of
any type in the rear seat
