Definitions

  • a safety hat 1 or helmet of any desired shape contains an energy absorbing liner that may be held in place by an adhesive or by an inner liner that fits inside the energy absorbing liner and is attached to the hat below it.
  • the way the liner is held in place forms no part of this invention.
  • the liner is formed from a plurality of upwardly tapered segments or columns 2 that curve upwardly and inwardly toward one another. The upper ends of these columns do not meet at a central point, but define the wall of a central polygonal opening that is fille by a center pad 3. This pad .and all of the columns around it are joined to one another by an adhesive to form the liner.
  • the tubes can all offer the same resistance to crushing, or they can be made in such a manner that different ones will require different pressures to crush them. In the latter case, the tubes are arranged in the stacks with the tubes at the inside of the liner the easiest to crush while the rest of them are progressively more difficult to deform ranging from the inside to the outside of the liner.
  • the different energy absorption characteristics of different tubes can be obtained by making them of different materials or in different sizes or wall thickness. The load or pressure against the outermost tubes is transmitted by them to all neighboring tubes, whereby the applied forces are dissipated over a large area of the liner. Also, there is some movement of the tubes against one another, which produces friction thatlikewise absorbs some energy.
  • the liner can be formed in the manner'indicated in FIG. 4 from a plurality of hexagonal members 10 that are fitted together in such a manner as to form a dome-like liner for a safety hat.
  • Each of the hexagonal members has side walls and parallel inner and outer walls formed from a thin plastic sheath 11.
  • Each sheath contains a stack of stiff deformable tubes 12 like those described above and arranged in superimposed rows, with the tubes in each row parallel and staggered relative to the adjoining rows, so that each tube engages two underlying tubes.
