Rear belts

Depending on the vehicle, these may consist of:

• belt pretensioners built into the retractors,
• load limiter.

These systems are designed to operate separately or together in the event of frontal impacts.

Depending on the severity of the impact, two cases are possible:

• only the seat belt provides protection;
• the pretensioner fires to take up belt slack.

Pretensioners for

Rear seat belts The system only operates once the vehicle ignition is switched on.

In a severe frontal impact, a device retracts the belt again, pressing it against the body and thereby increasing its effectiveness.

• After an accident, have all restraint systems checked.
• Any work on the complete system (pretensioners, airbags, electronic control units, wiring) or reuse on any other vehicle, even an identical one, is strictly prohibited.
• To prevent unintentional deployment that could cause damage, only qualified personnel from the brand network are authorised to work on pretensioners and airbags.
• Checking the electrical characteristics of the igniter must only be carried out by specially trained personnel using suitable equipment.
• When scrapping the vehicle, contact a Brand Representative for the disposal of the gas generator in the pretensioners and airbags.

Load limiter

Above a certain level of impact severity, this mechanism fires to limit the force of the belt on the body to a tolerable level.
