LOAD LIMITER OPERATION
BME081157000T04
-
Warning
-
• When the load limiter operates, the belt and anchor rub against each other strongly leaving a trace of wear. If the seat belt is used in this state, the seat belt will not function to its designed effect and there is the possibility of serious injury to passenger. Be sure to replace the seat belt once the load limiter operates.
ELR (Emergency Locking Retractor) Locks
• When the belt is extracted, the ELR lock mechanism is activated, and the pawl engages the housing gear. This locks the locking base as well as the torsion bar and guide drum integrated to the locking base.
