Abstract
A shock attenuation structure having a breadth greater than its thickness and a breadthwise cross section comprising a series of layers arranged side-by-side. The series of layers comprises a first plurality of layers of shock-absorbing material having a relatively high resistance to compression and a second plurality of layers of shock-absorbing material having a lower resistance to compression, the layers of the second plurality alternating with the layers of the first plurality across the breadth of the structure and providing lateral support to the layers of the first plurality. The structure is adapted to be mounted with its breadth generally perpendicular to the direction of impact force for broadside loading of the structure during an impact, the layers in the area of impact being adapted to deform for attenuating the shock resulting from the impact.
