METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS (continued)
Chest and lap belt force limiters
Above a certain severity of impact,
this mechanism is used to limit the
force of the belt against the body so
that it is at an acceptable level.
Driver and passenger airbags
Fitted to the driver and passenger
side.

indicated by the word Airbag on the
steering wheel and (depending on
the vehicle) the dashboard (airbag
zone A)andalabelonthelower
part of the windscreen.
Each airbag system consists of:
- an airbag and gas generator fitted
on the steering wheel for the
driver and in the dashboard for the
front passenger,
- an intelligent computer for both
systems, which includes an
impact sensor and a monitor
controlling the electrical trigger
system for the gas generator;
- a single indicator light on
the instrument panel.
The airbag system uses the
principles of pyrotechnics. This
explains why, when the airbag
inflates, it will generate heat,
produce smoke (this does not mean
that a fire is about to start) and
make a noise upon detonation. In a
situation where an airbag is
required, it will inflate
immediately and this may cause
some minor, superficial grazing to
the skin.
