Methods Of Restraint In Addition To The Rear Seat Belts - Renault LAGUNA Driver's Handbook Manual

METHODS OF RESTRAINT IN ADDITION TO THE REAR SEAT BELTS

Depending on the vehicle, they are
composed of:
– seat belt pretensioners built into
the inertia reels,
– force limiter.
These systems are designed to act
independently or together when the
vehicle is subjected to a frontal impact.
There are two possibilities, depending
on the force of the impact:
– protection is provided by the seat
belt only;
– the pretensioner is triggered to rec-
tify seat belt slack.
Rear seat belt pretensioners
This system is only operational when
the ignition is switched on.
If the vehicle is subjected to a severe
frontal impact, a device retracts the
seat belt, pulling the seat belt tight
against the body and thus improving its
effectiveness.
– Have the entire restraint
system checked following
an accident.
– No operation whatso-
ever is permitted on any part of
the system (pretensioners, air
bags, computers, wiring) and the
system components must not
be reused on any other vehicle,
even if identical.
– To avoid incorrect triggering of the
system which may cause injury,
only qualified personnel from an
approved dealer may work on the
pretensioner and air bag system.
– The electric trigger system may
only be tested by a specially
trained technician using special
equipment.
– When the vehicle is scrapped,
contact an approved dealer for
disposal of the pretensioner and
air bag gas generators.

Force limiter
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.
