COLLAPSIBLE STRUCTURE WITH VARYING STIFFNESS-BASED ENERGY ATTENUATION SYSTEM

摘要

A collapsible structure (20) is provided and includes a hub (30), an exterior skin (40) surrounding the hub (30) and a plurality of spokes (50) extending outwardly from the hub (30) to the exterior skin (40). Each spoke (50) is tapered along a length thereby providing varying stiffness based energy attenuation capabilities.
