Abstract: A protective hood molded to the contours of the interior of an aircrew helmet. The brow pad and a support panel are located within the protective hood. The custom fitting system, that adjusts the position of the support panel relative to the helmet, is located outside the hood. The custom fitting system is pivotally connected to the support panel, with the protective hood sealed around the pivotal connection. The brow pad and support panel lift the hood off the wearer's head, providing a gap to circulate ventilating air.

Abstract: A fitting assembly for a helmet having an interiorly located forehead dome and side sections. A crown pad provided with adjusting straps engages retention clips on the side sections to set the vertical position of the helmet. A nape panel provided with adjusting straps engages additional retention clips on the side sections to set the fore and aft position of the helmet. A pouch is fitted into the gap created between the dome and the forehead. A liquid foam is introduced into the pouch which expands and solidifies thereby creating a mold of the wearer's forehead. The pouch, nape panel and chip strap or breathing mask serve to lock the helmet in position on the wearer's head.
