ABSTRACT:
A shock attenuation system comprising a plurality of shock attenuating columns of a substantially resilient elastomeric material. The columns are so dimensioned and configured that, when subjected to an axial impact force of predetermined magnitude, they resiliently deform for attenuating the shock resulting from the impact force. The columns then spring back substantially to their undeformed shape.
