Abstract : A custom fitted pilot's helmet includes a liner attached within the confines of a helmet shell having numerous pressure relief holes over its entire surface. The liner includes a flexible sheet on one side of which is formed a plurality of elastic cell pairs separated by permanent heat seals or partitions overlaid with air tubes. The cells within a cell pair are separated from each other by a removable partition or severable heat seal. One cell of the cell pair contains one component of a foamable mixture and the other cell pair contains the second component of the foamable mixture. The linershell combination is positioned on the pilot's heat and the removable cell partitions are all virtually simultaneously removed. Thereafter, the foaming components within the cells admix and foam in situ to form a custom fitted helmet liner. (Author)
