Beschreibung
Zusammenfassung:	A cushioning and impact absorbing pad system with a surface layer of thickness t, and an elastomeric sub-surface structure of height h. The sub-surface structure comprises an array of elastomeric columns wherein each column has a frustoconical column wall surrounding a central void. The frustoconical column walls have a zone that is a more compressible, relatively collapsible zone in a region at an end of the column opposite the surface layer and a zone that is a relatively less compressible zone in a region at the end of the column abutting the surface layer. In other embodiments, pad thickness and column height are variable to create a surface which follows the contours of a human body.
