HELMET, PROCESS FOR DESIGNING AND MANUFACTURING A HELMET AND HELMET MANUFACTURED THEREFROM

摘要

There is provided a helmet engageable with a human head portion. The helmet includes an inner shell, an outer shell and a shock absorbing layer. The shock absorbing layer is located between the inner shell and the outer shell, include at least one 3D structure and is defined by a plurality of interconnected 5 surfaces with a plurality of openings defined inbetween. A designing process is provided, including steps of providing a virtual inner shell model and outer shell model of the virtual helmet model, positioning virtual curves on the virtual inner shell/outer shell model, and generating virtual minimal surfaces. A manufacturing process is 10 further provided, including steps of conceiving the virtual helmet model using at least some steps of the designing process and additive manufacturing at least a portion of the helmet.
