Abstract
A helmet, has a shell that includes a first portion and a second portion. The first portion has first, second and third layers. The second layer is positioned between the first layer and the third layer. The second layer is less dense than the first layer and the third layer. The second portion has a plurality of enemy dissipaters. Each of the energy dissipaters has a rod that extends in a spiraling manner from a fixed end to a free end. The rod tapers continuously along its length from the fixed end to the free end so that the fixed end exhibits a larger internal cross sectional area than the free end. The free end is capable of vibrating when the helmet is impacted by an object in order to dissipate impact energy.
