Abstract
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.
Claims18
A composite geometry structure for the absorption and dissipation of the energy generated by an impact comprising:
- an outer structure having a plurality of hollow cells passing therethrough, the outer structure being comprised of a plurality of sidewalls that are interconnected, each of the plurality of sidewalls encircling a corresponding one of the plurality of hollow cells and extending between an outside perimeter edge and an opposing inside perimeter edge;
- and
- a plurality of arc elements projecting from the outer structure, each of the plurality of arc elements having opposing ends projecting from spaced apart areas of a corresponding one of the plurality of sidewalls so as to span completely across the hollow cell of the corresponding one of the plurality of sidewalls in the shape of an arch, each of the plurality of arc elements projecting away from the hollow cell of the corresponding one of the plurality of sidewalls so that plurality of hollow cells are free of the plurality of arc elements, wherein each of the plurality of arc elements is configured to be elastically deformed and wherein each of the plurality of hollow cells is polyhedric-shaped.
