NETWORK STRUCTURE, CUSHIONING BODY, VEHICLE, AND METHOD FOR DESIGNING NETWORK STRUCTURE

摘要

A three-dimensionally networked cushioning body 12 has a network structure obtained by arranging a plurality of polyhedral frames 21 each of which is formed of a plurality of vertices arranged in a three-dimensional space and of connection members 25 connecting the vertices to one another. The plurality of polyhedral frames 21 are arranged regularly such that, when a certain load is applied thereto, the polyhedral frames 21 are displaced in a certain manner. Further, the plurality of polyhedral frames 21 are arranged such that one type of the polyhedral frames 21, which are truncated octahedrons, fills the space.
