Abstract
In order for protection criteria to be convincing, the dummy
used must behave in such a way that the choice of solutions
retained for occupant protection will be the same whether they
pertain to tests with dummies or to similar true life accidents
involving human beings.
This objective has not been completely reached using dummies
like the "Part 572" one. In lateral impact, a padding
convenient for a dummy can prove too resistive for a human thorax
and is therefore dangerous. In frontal impact, a belt implantation
can make the dummy, not a possible passenger, submarine.
Taking as reference biomechanical data obtained principally on
cadavers, the arms and the shoulders have been deeply modified and
a rib cage has been shaped with a flexibility similar to that of
human beings for the solicitations during side impacts. The new
thorax fulfills, in the case of frontal impact, the requirements of
the Part 572. However, the design allows conditions in frontal
impacts other than those of the Part 572 to be satisfied.
The adjustments to the pelvis have as a goal a more realistic
simulation of the submarining phenomenon. The dummy and results
obtained are presented here.
