Abstract
An elastomeric structure including two layers, the first having patterned openings therein and adjacent web members, the second including a patterned array of upstanding projections. The openings and projections may be of cylindrical, rectangular, or other configurations and are oriented in highly dense patterns. The elastomeric is positioned with and attached to a base member having a sidewall substantially as high as the corresponding external side surface of the elastomeric's first layer. The sidewall constrains the elastomeric during compression. The invention thereby substantially prevents lateral expansion of the elastomeric's side surface and lateral deflection of both layers, resulting in a uniform distribution of compressive forces on the upstanding projections.
