Energy Management Retractor
The front driver and passenger (if a passenger air bag
is fitted) seat safety belt retractors, attached to the
base of the B pillar, have an energy management
feature designed to provide a controlled amount of
webbing pay-out in severe frontal crashes. Once
activated, the spindle in the retractor deforms so that
the belt forces transferred to the occupant’s chest do
not rise above a predetermined load.
