Seat Belt Retractor: Description and Operation

AUTOMATIC RETRACTOR
When the front passenger's seat belt and the rear seat belts for the right and left seating positions 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.
