Seat Belt Systems: Description and Operation

Seat Belt

A: ADJUSTABLE SHOULDER BELT ANCHOR




1. FRONT
Each front seat belt system has an adjustable shoulder belt anchor which allows the occupant to select the most appropriate anchor height from among the five positions in a 100 mm (3.94 in) range.




2. REAR
The side rear seat belt system has an adjustable shoulder belt anchor which allows the occupant to select the most appropriate anchor height from among the three positions in a 36 mm (1.4 in) range.

B: REAR CENTER THREE-POINT TYPE SEAT BELT

Sedan:




1. SEDAN
A three-point type seat belt is available for the center seating position of the rear seat. The retractor for the seat belt is installed on the luggage shelf behind the seating position.

Wagon:




2. WAGON
A three-point type seat belt is available for the center seating position of the rear seat. The retractor is installed inside the right rear quarter panel.




C: AUTOMATIC RETRACTOR
When the front passenger's seat belt and all the rear seat belts are drawn out completely, their retractors are placed in the automatic locking mode which is used when installing a child restraint system. In this mode, the belt can be retracted but cannot be extended. When the belt is retracted to a certain length, this mode is canceled and normal operation is restored.

D: PRETENSIONER

1. CONSTRUCTION
The driver's and front passengers seat belts are equipped with seat belt pretensioners. The pretensioners use the front sub sensors and the airbag control module inside sensors to control their operation. If the sensors detect an impact exceeding the predetermined level during a frontal or front-angled collision, the front seat belts are quickly rewound by the retractors to take up slacks for maximum restraining of the seat occupants. If the load placed on a seat belt exceeds the predetermined level, the torsion bar twists to allow the belt to be payed out, thus lessening the load imposed on the belt wearer's chest. Once the seat belt pretensioner has been activated, the seat belt retractor remains locked.
