ABSTRACT:
An ancillary multichambered fluid-filled cushion for use as an energy-absorbing insert on the inside of protective headgear of the type having an outer helmet shell and a flexible inner liner. The chambers may be distinct or may be interconnected by means of communicating passages which control the flow of fluid between chambers. The chamber and communicating passages are formed of resilient material bonded together at perimeter flanges which may be engageable with the helmet inner liner so as to hold the cushion in place. The cushion is aligned intermediate the wearer's head and the outer shell, between existing inner liner components, so as to provide partial support of the helmet shell.
