GLOSSARY

Pre-tensioners

These are safety devices fitted to the front seat belts which replace normal reels.In the case of a fairly severe frontal impact the device, activated by a small explosive charge, intervenes preventing the sliding of the belt and thereby securing the occupant to the seat, overcoming the inertia force which would tend to project them forwards.

Submarining

This is the phenomenon which can occur in the case of a frontal impact.Even with the seat belt fastened, the body of the occupant of the seat tends to slide under the belt. 1, FRONT SEAT BELT 2, SECURING ROD 3, HEIGHT ADJUSTER 4, PRE-TENSIONER 5, REAR SEAT BELT 6, SECURING ROD 7, REEL

FRONT SEAT BELTS

The front seat belts, fitted with pretensioners, have a double mounting on the seat.In this way the belt follows the seat in the various positions it can assume, adapting to them to guarantee maximum safety in all situations.In addition, the shape of the seat cushion and the profile of the seat belt greatly limit the phenomenon of the body sliding under the belt in the case of a frontal impact (submarining).The belts are also height adjustable with a easily operated control. The management system for the pretensioners and side Air Bags is integrated with the Air Bags and is controlled by a single electronic control unit.For further information on the system  See subassembly 5580   SPECIAL ACCESSORIES - Air Bag System

REAR SEAT BELTS

The rear seat belts are integrated in the seats and the reel is not mounted on the floor, but fixed under the rear parcel shelf.This solution makes it possible to avoid the upper idler and ensure a better grip of the belt to the body and less elongation in the case of an accident.
