Impact absorber

摘要

A cellular component with cell walls aligned to be loaded in compression by an impact force applied to an impact surface of the absorber from which the cell walls extend laterally, wherein the cells walls are formed from multiple strips of material spaced apart across the impact surface but orientated so that adjacent sides of the walls abut and are joined at spaced regions along the length of the strips. The physical characteristics of the absorber can be varied to vary the impact absorbency longitudinally and/or laterally of the strips. The thickness of a cell wall can be varied either along one length of a strip and/or from one strip to another. The density or material of a cell wall can be varied. The depth of a cell may be adjusted by changing the width of a strip along a strip or from one strip to another. The cross-sectional area of a cell may be varied to give the cell a particular impact absorbency. The length of a joint between strips may also be varied.
