Seatbelt Load Limiter

It works together with the pretensioner and the airbag. A torsion bar inside the retractor often does the job. It reduces the risk of rib and chest injuries. Load limiters are set to work together with the airbag, which takes over some of the restraint.

Once belt force reaches a set limit, a torsion bar twists and allows controlled pay-out of the belt.

Seatbelts that have been loaded in a crash should be replaced. Belt clips or comfort devices can interfere with the system.
