Introduction

They consist of:

  • side seat belt inertia reel pretensioners;
  • chest force limiters.

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 cause:

  • blocking of the seat belt;
  • the seat belt inertia reel pretensioner (which engages to correct seat belt slack).

Load 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.

Side seat belt pretensioners

The pretensioners hold the seat belt against the body, holding the occupant more securely against the seat, thus increasing the seat belt's efficiency.

With the ignition on, following a significant frontal impact and depending on the severity of the impact, the system may trigger the seat belt inertia reel pretensioner 1 which instantly retracts the seat belt.

warning
  • Have the entire restraint system checked following an accident.
  • No operation whatsoever is permitted on any part of the system (pretensioners, airbags, computers, wiring) and the system components must not be reused on any other vehicle, even if identical.
  • Only qualified personnel from our Network may work on the airbags; otherwise the system may trigger accidentally and cause injury.
  • The electrical 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 airbags gas generators.
