Recently, there has been a movement to make bicycle helmets mandatory. One of the authors, Hagiwara et al. produce work helmets made of cardboard. And the helmet has already been well received. As since it follows the iron rule of "Using axial crushing of the pillar structure", a helmet is comparing to the conventional curved structure, it is very light and sufficient energy absorption can be obtained. For bicycles, energy absorption characteristics in all circumferential directions of the head is questioned. Here, we made a new hat based on Namako folding, and confirmed its effectiveness. In addition, we will try to prepare and construct a simulation model for the energy absorption effect to verify whether the helmet is resistant to impact.
