Seat Belt Retractor: Description and Operation
VEHICLE-SENSITIVE (EMERGENCY) LOCKING MODE
NOTE: The rear seat belts cannot be made to lock up by pulling quickly on the belt.
The vehicle-sensitive locking mode is the normal retractor mode, allowing free shoulder belt length adjustments to occupant movements and locking
in response to vehicle movements. If the driver brakes suddenly, turns a corner sharply or the vehicle receives an impact of approximately 8 km/h (5
mph), the combination safety belts will lock to restrain forward movement of the driver and passengers.
The front seat belt system can also be made to lock manually by quickly pulling on the shoulder belt.
AUTOMATIC LOCKING RETRACTOR (ALR) MODE
NOTE: The automatic locking retractor (ALR) mode is not available on the driver safety belt.
In the automatic locking retractor (ALR) mode, the shoulder belt is automatically pre-locked. However, the belt will still retract to remove any slack in
the shoulder belt. This mode is used any time a child safety seat is installed in an outboard seating position, or when a tight lap/shoulder belt fit is
desired. The ALR mode is automatically engaged when the webbing is fully extracted from the retractor. As the webbing is retracted back onto the
spool, an audible clicking sound is made, indicating that the retractor is in the ALR mode. The ALR mode is automatically disengaged when the
webbing is retracted back onto the spool. ALR mode is disengaged when the audible clicking sound ceases and the webbing is free to move in or out
of the retractor, indicating that the belt has returned to the vehicle sensitive (emergency) locking mode of operation.
Energy Management Retractor
This vehicle has a safety belt system with an energy management feature at the front seating positions to help further reduce the risk of injury in the
event of a head-on collision.
The energy management retractor feature is designed to pay out webbing in a controlled manner. This feature is designed to help reduce the belt force
acting on an occupant's chest.
