Head protection for reducing linear acceleration

摘要

Safety head wear for use for example in high risk activities such as sports and industrial purposes where protection from head injuries is required. Components are provided inserted between the liner and outer shell and consists of two parts; a pod and a foam or foam like surrogate or structure. The foam or foam like material is contained in the chamber and is positioned in such a way to create constant force between the surface of the shell and head. The device provides a method of managing compression force characteristics of the helmet around the head designed to decrease brain trauma resulting from high linear acceleration during impacts to the helmet.

主权项

1. Protective headwear for protection from a load generated by impact accelerations comprising:
an outer member for engaging external objects; an inner layer having an inner surface and an outer surface; a plurality of compressible components arranged between the outer member and the inner layer at spaced positions around the inner layer; the compressible components being arranged to compress in a direction generally orthogonal to the inner layer so as to absorb said load; each compressible component comprising:
a body having an inner surface for engaging the inner layer and an outer surface for engaging the outer member;the body comprising a tubular peripheral wall having the compression characteristics such that the tubular peripheral wall is collapsible longitudinally when a load is applied between the inner and outer surfaces greater than a predetermined load;and a compressible body located inside the tubular peripheral wall and having the compression characteristics to provide a resistance to compression;such that each compressible component responds to said load by combining the characteristics of the peripheral wall and the resistance to compression of the compressible body.
