Abstract
An object of the invention is to provide an impact energy absorbing structure in the form of resin moldings such as interior components of automobiles and other impact energy absorbing structures, with better impact properties, particularly the performance in absorbing impact energy to passenger heads. The invention relates to an impact energy absorbing structure for absorbing the kinetic energy of a colliding object by means of its own deformation, wherein when a certain colliding object collides with the impact energy absorbing structure at a certain velocity, the relationship between dimensionless displacement D, where the deformation of the impact energy absorbing structure is normalized by the permissible deformation, and the dimensionless energy E, where the kinetic energy absorbed by the impact energy absorbing structure is normalized by the kinetic energy of the colliding object prior to collision, meets E>D.
