geometry structure composite for the absorption and dissipation of the? energy produced by a collision and protective helmet comprising such structure

摘要

A composite geometry structure for the absorption and dissipation of the energy generated by an impact includes a plurality of hollow cells, adjacent and stably connected to each other. On each cell there are identified one or more arc elements which develop starting from two juxtaposed areas of the same perimeter edge of the cell, such arc elements being configured to be elastically deformed.
