Foam-In-Place Form Fitting Helmet Liners

摘要

The feasibility of a foamed-in-place, form fitting foam helmet liner for Air Force crash or flying helmets was proven. Polyurethane foam helmet liners may be foamed-in-place directly on the flying crew member's head, producing a perfectly fitting helmet liner with a minimum of time, labor, and inconvenience. A suitable polyurethane foam formulation was tailored to the specific requirements for the foam-in-place helmet liners. Design and fabrication of a suitable mold in which the helmet liner is foamed and which would be worn by the individual being fitted for a custom helmet liner during the foaming process, was accomplished.
