Abstract:
A method of absorbing energy from a moving object upon impact, where the method includes utilizing at least two types of energy absorbing elements to absorb at least some of the energy of the impact in an energy absorbing apparatus. A first type of energy absorbing element absorbs the majority of the energy absorbed by the apparatus and subsequent types of energy absorbing elements continue to absorb energy after the first type of energy absorbing element has ceased operation and can no longer absorb energy.
