Abstract
A sport helmet may include a first surface and a second surface opposite one another, and a lattice formed of flexible polymeric material, configured to deform from an initial shape upon an impact on the sport helmet and recover the initial shape thereafter to absorb at least part of the impact.

A sport helmet comprising:
- a first surface and a second surface opposite one another;
- and
- a lattice formed of flexible polymeric material, configured to deform from an initial shape upon an impact on the sport helmet and recover the initial shape thereafter to absorb at least part of the impact;
- wherein:
- the lattice comprises a regular geometrical arrangement of structural members that are formed of the flexible polymeric material, intersect one another at nodes, are integral and polymerized together at the nodes, and have designed dimensions, orientations and positions relative to one another individually controlled during formation of the structural members from the flexible polymeric material;
- and respective ones of the nodes of the lattice are spaced from one another in three orthogonal directions that include a thickness-wise direction of the sport helmet from the first surface of the sport helmet to the second surface of the sport helmet.
A sport helmet comprising:
- an outer shell;
- and
- a liner disposed within the outer shell and comprising a lattice;
- wherein:
- the lattice is formed of flexible polymeric material, is configured to deform from an initial shape upon an impact on the sport helmet and recover the initial shape thereafter to absorb at least part of the impact, and occupies at least a majority of a dimension from an exterior surface of the outer shell to an interior surface of the liner;
- the lattice comprises a regular geometrical arrangement of structural members that are formed of the flexible polymeric material, intersect one another at nodes, are integral and polymerized together at the nodes, and have designed dimensions, orientations and positions relative to one another individually controlled during formation of the structural members from the flexible polymeric material;
- and respective ones of the nodes of the lattice are spaced apart from one another in three orthogonal directions that include a thickness-wise direction of the sport helmet from the exterior surface of the outer shell to the interior surface of the liner.

- a liner disposed within the outer shell and comprising a lattice;
- wherein:
- the lattice is formed of flexible polymeric material and is configured to deform from an initial shape upon an impact on the sport helmet and recover the initial shape thereafter to absorb at least part of the impact;
- the lattice comprises struts that are formed of the flexible polymeric material, intersect one another at nodes, are integral and polymerized together at the nodes, and have designed dimensions, orientations and positions relative to one another individually controlled during formation of the struts from the flexible polymeric material;
- respective ones of the nodes of the lattice are spaced apart from one another in three orthogonal directions that include a thickness-wise direction of the sport helmet from an exterior surface of the outer shell to an interior surface of the liner.
A method of manufacturing a liner for a sport helmet, the method comprises forming a lattice of the liner, the lattice comprising a regular geometrical arrangement of structural members that are formed of flexible polymeric material, intersect one another at nodes, and are integral and are polymerized together at the nodes, wherein said forming comprises individually controlling designed dimensions, orientations and positions of structural members relative to one another during formation of the structural members from the flexible polymeric material.
