Cushioning elements comprising buckling walls and methods of forming such cushioning elements

Abstract

Cushioning elements having a top cushioning surface and a bottom base surface include an elastomeric cushion member and a stabilizing material. The elastomeric cushion member includes a first plurality of interconnected buckling walls having a first mean height and a second plurality of buckling walls having a second mean height. Each buckling wall of the second plurality intersects and connects to at least two buckling walls of the first plurality. A surface of the stabilizing material on a side thereof opposite the elastomeric cushion member defines the bottom base surface of the cushioning element. The first ends of the first plurality of interconnected buckling walls and the first ends of the second plurality of buckling walls define the top cushioning surface of the cushioning element. Methods of forming cushioning elements include securing a stabilizing material to ends of the first plurality of interconnected buckling walls.
