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 cancelled and normal operation is restored.

CONSTRUCTION

The driver's and front passenger's 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 pulled 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.

DRIVER'S PRETENSIONER

The gas generator is activated.

The generated gas pushes the steel balls.

Moving steel balls cause the ring gear to rotate.
