CONCERTINAED STRUCTURES IN PROTECTIVE GEAR

摘要

Protective gear such as a helmet includes multiple shell layers connected using one or more concertinaed structures. The concertinaed structures allow the shell layers greater flexibility to move relative to each other when mechanical forces are imparted onto the outer shell layer. When energy and impact transformer layers are disposed between the shell layers, the concertinaed structures may also allow improvement function of the energy and impact transformer layers.

1. A helmet, comprising:
an outer shell layer; a middle shell layer; an inner shell layer; and a first concertinaed structure connecting the outer shell layer to the middle shell layer, wherein the first concertinaed structure allows the outer shell layer to move relative to the middle shell layer when mechanical forces are imparted onto the outer shell layer.
