Abstract
A shock-absorbing structure component has two cover layers and an intermediate layer that is arranged between them. The intermediate layer extends in an alternating form between the cover layers, with the material of the intermediate layer being selected such that it has a higher capacity elongation prior to breaking than that of the outer cover layer. The energy of an impact can thus be absorbed as the intermediate layer is stretched into a bag shape and the inner cover layer breaks off progressively.
