1. A method for designing an energy-absorbing impact zone for a vehicle interior, comprising:

  • acquiring test data representative of an occupant impacting the impact zone;

    determining a force versus deflection curve for the impact zone;

    analyzing the force versus deflection curve;

    adjusting the stiffness of the impact zone;

    shaping the force versus deflection curve without exceeding a certain force limit and a certain head impact criterion.
