Abstract
A helmet for improved impact protection includes a shell and a first pad disposed within the shell. The first pad includes a first lattice structure with at least one LCE pillar. In some aspects, the helmet includes a plurality of pads. Each pad may include multiple regions. Each region of a pad may be comprised of different lattice structures, some of which contain LCE pillars and some of which do not.
Claims12
A pad for a helmet, the pad comprising:
- a first lattice structure comprising a buckling column, an LCE column, and a plurality of struts extending between the buckling and LCE columns;
- and
- an LCE pillar disposed within the LCE column,
- wherein the LCE pillar comprises an LCE chemistry having a first mesogen and a second mesogen, and wherein the LCE pillar is press fit into the LCE column.
