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

SYSTEMS IN ADDITION TO THE FRONT SEAT BELTS
Depending on the vehicle, they are
composed of:
– seat belt pretensioners;
– chest-level load limiters;
– air bags for the driver and front pas-
senger.
These systems are designed to act in-
dependently or together when the vehi-
cle is subjected to a frontal impact.
Depending on the severity
of the impact, the system
can trigger:
– seat belt locking;
– the seat belt pretensioner to hold
the occupant in the seat, and the
force limiter;
– the front air bag.
Pretensioner
With the ignition switched on, if the
vehicle is subject to a significant fron-
tal impact the system may, depending
on the severity of the impact, trigger a
piston which instantly retracts the seat
belt.
The pretensioner holds the seat belt
against the body, holding the occupant
more securely against the seat, thus in-
creasing the seat belt's efficiency.
(1/4)
– Have the entire restraint
system checked following
an accident.
– No operation whatsoever
is permitted on any part of the
system (air bags, electronic con-
trol units, wiring) and the system
components must not be reused
on any other vehicle, even if iden-
tical.
– To avoid premature triggering
of the system which may cause
injury, only qualified Network per-
sonnel are authorisedto work on
the methods of restraint in addi-
tion to the front seat belt.
– 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
airbag gas generators.
