Abstract
A protective helmet for use particularly by the rider of a two-wheeled vehicle, having an upper rigid shell joined to a semi-rigid shell of plastic material, the latter having extensions over the regions of a wearer's ears. An interior shock absorbing element is composed of two parts, the upper part extending frontwardly and rearwardly as far as the lower part, which is ring-like in form and extends around the entire lower interior part of the head, to provide protection in the rear.
