Patent ID: 8376456

Claim:
An impact absorbing structural body comprising a laminated body obtained by laminating at least two layered planar members made of heterogeneous materials, wherein the laminated body is comprised of planar members made of synthetic resin and a planar member made of cloth, is configured by sandwiching the planar member made of cloth between the planar members made of synthetic resin, and is configured such that, by action of delamination caused between respective layers upon receipt of an impact, both the tensile stress and the Izod impact strength of the laminated body regarding at least one tensile direction of a vertical direction, a lateral direction and an oblique direction are lowered as compared with those of a homogeneous laminated body obtained by laminating a planar member made of a homogeneous material on either of the planar members used in the laminated body, and lowering rates of the tensile stress and the Izod impact strength are 40% or less, wherein an undulation portion is formed on the laminated body.
