Methods Of Restraint In Addition To The Front Seat Belts - Renault 2009 CLIO Handbook

METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS

Depending on the vehicle, they are
composed of:
– seat belt inertia reel pretension-
ers;
– lap belt pretensioners;
– chest-level load limiters;
– anti-submarining air bags;
– air bags for driver and front pas-
senger.
These systems are designed to act
independently or together when the
vehicle is subjected to a frontal impact.
Depending on the severity of the impact,
the system can trigger:
– seat belt locking;
– the seat belt inertia reel pretensioner
(which engages to correct seat belt
slack);
– the front air bag;
– the lap seat belt pretensioners to
hold the occupant in his seat.

Pretensioners
The pretensioners hold the seat belt
against the body, holding the occupant
more securely against the seat, thus in-
creasing the seat belt's efficiency.
In the event of a severe frontal impact
and if the ignition is switched on, the
system may engage the following de-
pending on the force of the impact:
– seat belt inertia reel pretensioner 1
which instantly retracts the seat belt;
– lap belt pretensioner 2 on the front
seats or anti-submarining air bag 3.
– Have the entire restraint
– 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
1
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.
