(b) Load Limiters:
Load limiters are to be used only in airbag
equipped vehicles. Load limiters are provided to
limit the seat belt loads to a pre-defined value.
The load limiter fitted inside the retractor unit is
basically a torsion bar
Whenever the belt load increases beyond the pre-
defined limit, some length of the belt is released
due to twisting of the torsion bar. The activation of
the load limiter does not depend on signal from
the ECU.
