Abstract
A protective helmet for providing protection against impact to a wearer's head. The helmet includes a helmet shell and an apparatus or component which provides for sizing and energy absorbing capabilities. This component is made of a mesh tube with loose beads of an energy absorbing material stuffed into it. The stuffed tube is flexible, preferably being coiled onto a comfort line and secured to it. The comfort liner and stuffed tube are then attached to the helmet shell. The loose beads are adjustably moveable in response to a slight amount of steady pressure as applied during donning of the helmet, to adjust so as to provide a comfortable fit to the wearer. Preferably the mesh tube is of a knitted fabric, while the beads are preferably of polystyrene. Typically, the comfort liner is of perforated leather, to be breathable.
