Abstract
An impact attenuation lattice structure includes a plurality of unit cells. Each of the plurality of unit cells has a horizontal plane, a central axis, and a plurality of struts that form a plurality of sidewall frames. Each of the plurality of sidewall frames are angled relative to the central axis and the horizontal plane is perpendicular to the central axis. The plurality of unit cells are connected to one another to form a lattice structure. A first unit cell of the plurality of unit cells share one sidewall frame of the plurality of sidewall frames with a second unit cell of the plurality of unit cells adjacent to the first unit cell. The second unit cell is in an inverted position about the horizontal plane compared to the first unit cell.

An impact attenuation lattice structure comprising:
- a plurality of unit cells, each of the plurality of unit cells having a horizontal plane, a central axis, a first end, a second end opposite the first end, and a plurality of struts forming a plurality of sidewall frames, each of the plurality of sidewall frames angled relative to the central axis such that the second end of each of the plurality of unit cells is wider than the first end, the horizontal plane being perpendicular to the central axis,
- wherein the plurality of unit cells are connected to one another to form a lattice structure, a first unit cell of the plurality of unit cells sharing one sidewall frame of the plurality of sidewall frames with a second unit cell of the plurality of unit cells adjacent to the first unit cell, and the second unit cell being in an inverted position about the horizontal plane compared to the first unit cell.
An impact attenuation lattice structure comprising:
- a plurality of unit cells, each of the plurality of unit cells having a horizontal plane, a central axis perpendicular to the horizontal plane, a first end, a second end opposite the first end, and a plurality of struts forming a plurality of sidewall frames, each sidewall frame having a geometric shape devoid of cross members and being angled relative to the central axis such that the second end of each of the plurality of unit cells is wider than the first end, each of the plurality of sidewall frames disposed along a perimeter of the unit cell and coupled together by one or more spacing struts,
- wherein the plurality of unit cells are connected to one another to form a lattice structure, a first unit cell of the plurality of unit cells sharing one sidewall frame of the plurality of sidewall frames with a second unit cell of the plurality of unit cells adjacent to the first unit cell, the second unit cell being in an inverted position about the horizontal plane compared to the first unit cell.
