For the first time ever, it is possible
to close the gap between a wrecked car and the occupant or occupants. The
Safety Follow-up Dummy, SFD, is adjustable
in length and width. In contrast to all other dummies it can mimic
one specific person’s size, thus making
it easier to establish in greater detail what occured and visualize how
it
looked in a certain vehicle during a real
life impact.
The SFD, invented by former crash investigator
Sverker Dahl, Sweden, is designed to be easy to operate and will
be supported by a software system suitable
for both in depth analysis of a single crash or, used systematically, for
following up many crashes to find possible
patterns in the relations between the victims and the vehicles.
For obvious reasons a victim is never repostioned
in the vehicle he or she was injured or killed in. That ethical
circumstance many times makes it hard
for professional crash investigators to find the real reason for a certain
injury or ceratin injuries and it makes
it almost impossible for a layperson, for example a judge or juror, to
understand the origin of an injury.
SFD makes it easier to understand what
happened
The SFD:s spine, upper and lower arms and
legs are adjustable in length and the shoulder, hip and cheast areas
are adjustable in width. All joints have
a range of movement similar to thoose of a human being. The dummy is
light weight, easy to use and offers the
possibility to be placed in the wreck either as a whole structure or part
by
part. The dummy can be disassembled in
order to be stored or carried in a box or case.
These unique characteristics combined with
the victims specified injuries makes the investigation easier. Used on
a large number of cases SFD will be able
to detect for example the differences in injury panorama between short
and tall occupants. It also makes it possible
for persons with limited knowledge about vehicle crashes to better
understand what really happened in the
actual impact.
