Abstract
A combined program of accident investigation, staged collisions, and simulated collisions involving three-point harnessed occupants in frontal force collisions has provided a means of correlating injury with forces and/or other physical parameters associated with the injuries. The harness is highly efficient in mitigating injuries, rib and sternum fractures are the more prevalent injuries, submarining is not a major problem, females are injured at lower collision severity than males, and age is an important factor in injury susceptibility.
