Rear Seat Belts And Buckles

All three rear seating positions are equipped with three-point seat belt systems. The outboard seating position belts employ lower C-pillar mounted inertia latch-type emergency locking retractors, fixed position upper C-pillar mounted turning loops and fixed lower seat belt anchors secured to the rear floor panel. The rear seat center seating position has an inertia latch-type emergency locking retractor that is secured within the left seat back and has a dedicated, keyed anchor buckle that allows the belt anchor to be quickly detached when the left rear seat back is folded down for additional cargo space. In the NAFTA market, all of the rear seat belt retractors for this vehicle are also switchable from an emergency locking retractor to an automatic locking retractor for compatibility with child seats. The center seating position belt lower anchor buckle is secured along with the right outboard seat belt buckle to the rear floor panel. All three rear seat belts have fixed end-release seat belt buckles.

The seat belt retractors used in all seating positions include an inertia-type, emergency locking mechanism as standard equipment. The outboard rear seat belt retractors in vehicles manufactured for Europe-Middle East-Africa (EMEA) markets include a retractor tensioner and the load limiting feature.

The standard inertia-type emergency locking retractor will allow the seat belt webbing to unwind from and wind onto the retractor spool freely unless and until a predetermined inertia load is sensed. The retractor has an internal inertia latch mechanism that will lock the retractor spool once the predetermined inertia load is sensed. Locking the retractor spool prevents the seat belt webbing from being extracted from the retractor and firmly restrains the occupant wearing the seat belt. The retractor spool is automatically unlatched once the loading of the retractor inertia mechanism and the seat belt are relieved.

The emergency locking mechanism, the retractor tensioner mechanism and the load limiting feature are each integral to the retractor unit and are concealed beneath molded plastic covers located on each side of the retractor spool. These features cannot be adjusted or repaired and if ineffective, damaged or deployed, the entire seat belt and retractor unit must be replaced.
