Abstract:
1. An elongated impact-absorbing member, which is made of synthetic resin material, and is adapted to be disposed in a load-receiving member struck by an impactor in a portion thereof that is struck by the impactor, the impact-absorbing member comprising: a plurality of tabular ribs extending in a direction orthogonal to an impact load input direction of impact load produced by striking by the impactor, and being disposed spaced apart in the impact load input direction such that all of the plurality of tabular ribs are substantially parallel to one another; and a load transmitting member connected with width-wise opposite ends of the respective tabular ribs so as to extend between the tabular ribs on a diagonal with respect to the impact load input direction, for transmitting to each of the plurality of tabular ribs the impact load in a form of tensile load directed in a lateral direction, wherein differing levels are established for at least one of: tensile stiffness in the plurality of tabular ribs; and transmission efficiency of the tensile load by the load transmitting member, so that load-deformation characteristics of some of the plurality of tabular ribs differ in the impact load input direction.
