ABSTRACT:
A substantially rigid dome-shaped shell encloses a deformable cap-like headpiece of uniform thickness. The headpiece conforms to the contour of the wearer's head and cooperates with the shell to define a dome-shaped cavity which is sealed around its bottom portion. The cavity is filled with an expandable plastics foam material which hardens and conforms to the contour of the headpiece. In one embodiment, spacer members are positioned within the cavity and extend from the headpiece to the shell for positioning the shell relative to the headpiece, and in another embodiment, the shell is spaced within a slightly larger outer shell by resilient energy-absorbing foam pads. In a further embodiment, separate earpiece units are contour fitted to the wearer's head with a resilient expandable plastics foam material, and a modified helmet shell is used as a holder for fitting the headpiece and earpiece units.
