Abstract: The lower extremity forces developed during vehicle accidents
with significant floor pan intrusion are considered, and the
forces generated directly by the intrusion are focused on . The
analysis is based on the modification and use of SUPERCRASH-a
multibody crash computer simulator. For 48 km/h frontal
collisions, the results show that there is marked asymmetry on
the forces exerted on the left and right legs, arising due to
the asymmetrical restraint of the 3-point seat belts. The
results also show, as expected, that floor pan intrusion
reduction will greatly reduce the forces on the lower
extremities.
