Restraint systems (Description): Description and operation

Description

General

Seat belts are provided as the primary restraint for all occupants. An inertia reel, three point seat belt is installed at each seat position. A load limiter feature is incorporated into the inertia reels on NAS vehicles and is available as an option in all other markets.

On NAS vehicles, the inertia reel of the driver's seat belt is the Emergency Locking Retractor (ELR) type and the inertia reel for all of the passenger seat belts are the Automatic Locking Retractor (ALR) type. In all other markets ELR inertia reels are fitted at all seat positions.

Both types of inertia reel incorporate a liftshaft locking system with webbing sensor and car sensor activating mechanisms. The webbing sensor activates the locking system if the webbing is subjected to a sharp pull. The car sensor activates the locking system if the vehicle is subjected to sudden deceleration or a severe tilt angle.

Front Seat Belts

The inertia reel of each front seat belt is attached to the related B/C post, behind the finishers. The webbing runs from the inertia reel, through an upper mounting attached to a height adjuster on the B/C post, to an anchor point either at the base of the B/C post (five door models), or on a bar attached to the inner sill (three door models).

The buckle assembly for each belt, consisting of a buckle attached to a flexible stalk and an integrated pretensioner, is secured to the inboard side of the related front seat frame.

Rear Seat Belts

Inertia reel seat belts are installed for all of the rear seats.

Three Door Models The inertia reel of each rear seat belt is attached to a bracket on top of the related rear suspension turret, behind the loadspace rear quarter trim. The webbing runs from the inertia reel, through an upper mounting on the D post, to an anchor point in the rear wheel arch.

The buckle for each belt is directly attached to the inboard side of the related rear seat frame.

Five Door Models The inertia reel of each outboard rear seat belt is attached to the related D post, behind the D/E post finisher. The webbing runs from the inertia reel, through an upper mounting on the D post, to an anchor point in the rear wheel arch.

The inertia reel for the centre rear seat belt is installed in a recess in the back of the rear seat. The webbing runs from the inertia reel, over the top of the seat, to an anchor point in the lower frame of the right rear seat.

The buckle assembly for each belt, consisting of a buckle attached to a length of webbing, is fixed to the lower frames of the rear seats. The buckle assembly for the right seat belt shares an anchor point with the webbing of the centre seat belt.
