Abstract

Abstract An individualized helmet assembly and method of and apparatus for making the same in which a helmet liner having a plurality of apertures is removably secured inside a fixture in the form of a rigid template simulating a helmet shell and having apertures registering with the apertures in the liner. Resilient, snugly fitting spacer plugs are inserted in the apertures from the inner side of the liner, and the entire assembly is placed over the wearer's head. Selected plugs are pushed inwardly against the head of the wearer properly to position and stabilize the helmet-simulating fixture and liner on the wearer's head. The remaining spacers are then pushed inwardly until they abut the wearer's head. Finally, with the assembly removed from the wearer's head, the portions of the spacers protruding outwardly from the template are cut off, and the liner is separated from the template and assembled with an outer helmet shell to complete the construction.
