Abstract
A helmet an include a shell, a liner disposed within the shell, a flexible band disposed between the shell and a portion of the liner to releasably couple the liner to the shell without glue, hook and loop fasteners, or snaps. The helmet can also include an energy-absorbing layer of expanded polystyrene (EPS) including a groove. The comfort liner can be attached to the energy-absorbing layer without glue, hook and loop fasteners, or snaps, and a flexible band can be releasably disposed between the energy-absorbing layer and the comfort liner. The helmet can also include a groove on an inner surface of an outer shell. An energy-absorbing liner can include expanded polypropylene (EPP), and a flexible band can be disposed between the outer shell and the energy-absorbing liner to provide additional energy management, to releasably couple the energy-absorbing liner to the outer shell, or both.
