Abstract
The wearing of the so-called three-point seat-belt has
unquestionably brought about a decrease in both the frequency and
the seriousness of the injuries sustained by automobile accident
victims, when one compares the injuries incurred by the wearers of
these belts with the injuries suffered by non-belt wearers in
accidents of comparable impact violence.
However, the standard seat-belt still has room for considerable
improvement. The injury-provoking mechanisms and the tolerances of
the head and thorax are fairly well known, and this knowledge has
enabled definition of protection criteria for frontal collisions
simulated with dummies; the situation is different as concerns the
abdominal viscera and the lumbar spine. However, injuries of this
type are not inconsiderable in the light of the realities
concerning accidents involving seat-belt-wearers.
In what follows, after evaluating the extent of
submarining-induced injuries, it is proposed to compare those of
the real-life victims and those of the cadavers used in frontal
impact simulations. An attempt is then made to define as accurately
as possible the conditions associated with dangerous submarining,
from the viewpoint of a specific protection criterion.
