    In the earthquake, the helmets play an important role in protecting the head of people, so the helmet needs to be less than 300 mm×200 mm×50 mm and should be put in the emergency bag for the time being. The existing helmets can't satisfy the requirement. In order to achieve the target, a foldable helmet is inspired by Origami engineering.

     Based on the MHLW helmet standards, a foldable helmet consisting of accordion cover origami structure/honeycomb origami structure is applied and the impact characteristic of the foldable helmet is investigated by FEM analyses and experiments.

     On the basis of this new foldable origami helmet that has been confirmed in satisfying the requirements of saving and safety, in order to make the foldable origami helmet be used for infants, the RSO structure is added. Finally, the improved helmet satisfied higher safety standards and could be put in the small box at the same time.
