ABSTRACT:
An individually fitted helmet liner includes a plurality of superposed contacting layers, each of which consists of a thermoplastic sheet formed with an array of pockets which are open and unfilled to allow their deformation in response to compressive contact with an adjacent layer. The liner is fitted to an individual wearer's head by heating the sheets to a plastic state, placing the liner between an outer shell and the wearer's head, and pressing down on the outer shell to deform the sheets to the proper extent.
