Load limiter
-
• The load limiter adjusts the restraint force of the seat belt by slightly loosening the seat belt tightened by the pre-tensioner operation, preventing injury to the driver and passenger from seat belt pressure.
ELR (Emergency Locking Retractor)
-
• If a sudden force is applied to the seat belt such as by a collision or emergency braking, the ELR locks the seat belt so that it cannot be pulled out any more.
ALR (Automatic Locking Retractor)
-
• When the seat belt is pulled out and fastened, the ALR locks the seat belt at that length and it cannot be pulled out any more.
• The ALR is mainly used for installing a child-restraint.
Pre-tensioner seat belt

Construction
• For the three-point seat belt, the seat belt is secured to the drum in the retractor and wrapped.
• The seat belt is pulled out or retrieved by the rotation of the drum to adjust the length of the seat belt.
