Integrated helmet system

摘要

An integrated helmet system for presenting the wearer with visible images in which an outer helmet providing a surface on which the images are projected is adapted to be assembled on the frame of an inner helmet having a headband on which the frame is mounted for adjustment in front to back and side to side directions. A fixture adapted to be mounted on the frame provides a simulation of the images to be presented to the wearer on a surface positioned in front of the frame at a distance equal to the distance between the frame and the outer helmet viewing surface when the outer helmet was assembled on the frame, thus to permit the frame to be adjusted relative to the headband so that the outer helmet viewing surface is properly positioned with reference to the wearer's eyes when the outer helmet is assembled on the inner helmet.
