Seat Belt Retractor: Description and Operation
Dual Locking Mode Retractor
NOTE: when replacing a dual locking mode retractor, the retractor should be checked to make sure it is not in the Automatic Locking Mode (ALR)
after installation in the stowed position.
All outboard continuous-loop, three-point retractor systems, except the driver position, are equipped with the dual locking mode system.
The Emergency Locking Retractor (ELR) mode will allow the occupant freedom of movement, locking tight only on hard braking, hard cornering, or an
impact of approximately 8 km/h (5 mph). The ELR mode helps to reduce the forward movement of the driver and passengers. The Emergency Locking
Retractor (ELR) mode is continuously in operation at all seating positions.
The ALR portion of this system does not allow the occupant freedom of movement. The ALR mode is used when locking a child seat in an outboard
seating position or when a tight belt fit is desired. The ALR mode is disengaged when the webbing is free to move in or out of the retractor. The ARL
mode is automatically engaged when the webbing is fully extracted from the retractor and then allowed to retract. As the webbing is retracted back onto
the spool, an audible clicking sound is made indicating the retractor is in ALR mode. The ALR mode is automatically disengaged when most of the
webbing is retracted back onto the spool.
