Abstract
A method is disclosed for designing an energy-absorbing impact zone for a vehicle interior, including acquiring test data representative of an occupant, determining a force versus deflection curve for the vehicle impact zone, analyzing the force versus deflection curve, and utilizing the analysis to adjust the stiffness of the energy-absorbing impact zone and to shape the force versus deflection curve so that a constant area under the force versus deflection curve has the minimum deflection possible without exceeding a certain force limit and a certain head impact criterion.
