ABSTRACT:
An improved fireman's helmet is disclosed which includes an outer shell, a compressible, non-resilient foam liner, and an inner shell of hemispherical shape conforming to the foam liner. An annularly extending channel of generally U-shaped cross-section is integrally formed on and around an outer edge portion of the inner liner into which an edge portion of the foam liner is disposed. A series of flexible, stretchable, resilient crossing one another at an apex, extend radially outwardly and downwardly from the apex and extend under and across the channel, thence upwardly between the liner and the outer shell to connections on distal end portions thereof with rigid, non-resilient, incompressible anchors resting on a floor of the channel. The anchors are disposed within open slots formed in and around outer surface portions of the liner. Apex impact forces applied to the helmet thus tend to be essentially entirely absorbed without causing deformation of the non-resilient foam liner at the anchor locations, at least within the design limits of the helmet.
