It is formed of a cushion that inflates in-
stantaneously contained in a special recess:
– in the centre of the steering wheel for
the driver;
– in the dashboard and with a bigger cush-
ion for the passenger.
The front Air bag (driver’s and passenger’s)
has been designed to protect the occupants
in the event of head-on crashes of medium-
high severity, by placing the cushion be-
tween the occupant and the steering wheel
or dashboard.
In the case of a crash, an electronic con-
trol unit processes the signals leading from
a deceleration sensor and, when necessary
triggers inflation of the cushion.
The cushion inflates instantaneously, set-
ting itself between the body of the front oc-
cupants and the structures that could cause
injury. The cushion then deflates immedi-
ately afterwards.
The front air bag (driver’s and passenger’s)
does not replace but is complementary to
the use of belts, which should always be
worn, as specified by law in Europe and
most non-European countries.
In the event of a crash a person that is not
wearing the seat belt moves forwards and
may come into contact with the cushion
while it is still opening. Under these cir-
cumstances the protection offered by the
cushion is reduced.
Front air bags designeed to protect car’s
occupants in front crashes and therefore non-
activation in other types of collusions (side
collisions, rear-end shunts, roll-overs, etc...)
is not a system malfunction
In collisions against highly deformable or
mobile objects (road signposts, heaps of ice
or snow, etc.), rear collisions (hit from be-
hind by another vehicle), side collisions,
wedging under other vehicles or protective
barriers (for example under a lorry or guard
rail) cutting in of the air bag is not activat-
ed as it does not offer any more protection
than the seat belts therefore activation
would be inappropriate.
Therefore the failure to be triggered does
not mean that the system is not working
properly.
