Emergency Locking Retractor (Elr) - Aston Martin V8 Vantage Workshop Manual

Restraining Devices (01.20)
Body System (01.00)
mounted onto a spindle (torsion bar) which once the sensor
has locked the retractor reel and a predetermined load is
applied, twists and allows additional webbing into the
system. The deceleration force required to initiate this
sequence is approximately the same as that required to
initiate airbag deployment. The torsion bar load limiting
device will only react if the safety belt is in use at the time of
the impact.
It should be considered that during any event that
utilizes the full capability of the safety belts, the
webbing may have been elongated and the torsion bar
may have twisted. For this reason, if a vehicle is
involved in an accident which results in the deployment
of the airbag(s), all the safety belts that were in use at
the time of the accident MUST be renewed.

Emergency Locking Retractor (ELR)

The retractors in all seat positions feature ELR. During any
period of sudden deceleration, or under lateral load when
cornering at speed, a sensor weight within the safety belt
retractor moves a locking pawl against the teeth on the
retractor reel, which then locks the retractor preventing any
further release of webbing. As soon as the load applied onto
the retractor through the safety belt webbing is removed the
locking pawl releases the retractor reel and normal
movement is returned to the retractor.
Automatic Locking Retractor (ALR)
Automatic locking retractors (ALR) are installed to all
passenger seat positions.
The safety belt webbing on these are clearly marked to show
their operating feature. To initiate the ALR system, fasten the
safety belt into it's buckle and pull all of the webbing from
the retractor, as the safety belt is released the retractor locks
allowing travel in only one plane thus producing a fixed
length restraint and preventing the safety belt from
introducing slack, making any child seat it may be restraining
secure. The ALR system of the retractor is disengaged by
releasing the safety belt and allowing the safety belt to fully
retract onto the reel.
