Abstract
Several crash investigation studies recently lead to opposing
conclusions on the importance of abdominal injury risk to children.
This paper deals with an in-depth and synthetic analysis of new
accidentological data. In particular, the risk is studied by
isolating parameters such as age and crash type, as well as
restraining systems.
The abdominal risk appears higher above 2 or 3 years old for
children using poorly designed booster cushions or adult belts
alone.
The prevention of such a risk for protected children should be
given by a pertinent restraint-system assessment in frontal impact
simulation. Unfortunately, the lack of biofidelity of the
pelvic-abdominal segment of the current child dummies does not
allow this child restraint assessment. Data for the improvement of
dummy pelvises and for the definition of an abdominal criterion are
provided in this paper.
The authors propose the use of geometrical criteria to
differentiate poor and acceptable booster cushions, as a temporary
measure, until effective abdominal injury assessment becomes
possible.
