摘　　要：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.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.
