Upon hitting by an object, ,the helmet, dissipates some of the energy in the following mechanisms: (i) Stretching of harness ,inside the helmet,; (ii) Partial damage of outer shell of ,helmet,.
Suspension bands ,inside the helmet, spread ,the helmet,'s weight and the force of any impact over the top of the ,head,. A suspension also provides space of approximately 30 mm (1.2 inches) between ,the helmet,'s shell and the wearer's ,head,, so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull.
