ADJUSTABLE HELMET

摘要

The invention relates to a helmet comprising a mechanism to increase or decrease the internal volume thereof through the displacement of one or more portions of the protective material lining the helmet shell. The invention includes an adjustment mechanism mounted on or adjacent the shell of the helmet, from which project one or more connectors which are operationally connected to the movable portions of the protective material. When the adjustment mechanism is activated, for example clockwise or counterclockwise, the connectors are displaced, which causes the movable portions of the protective material to either be displaced away from the shell of the helmet or towards the shell of the helmet and thus allowing for a fine tuning of the fit of the helmet on a player's head.
