Claim Text:
1. A modular energy absorbing system that is interposed between a lower foundation and an upper impact-receiving surface, the energy absorbing system comprising: a plurality of energy absorbing modules that cooperate to absorb at least some impact forces exerted upon the upper impact-receiving surface, the modules also being operable to space apart the upper impact-receiving surface and the lower foundation; at least some of the plurality of energy absorbing modules comprising one or more frustoconical support structures, at least some of the frustoconical support structures having a bottom surface and an upper top surface that are connected by a frustoconical sidewall, the upper top surface being operable to coordinate the response of the frustoconical support structures to impact; and the upper top surface underlying the upper impact-receiving surface and the bottom surface being juxtaposed with the lower foundation, at least some of the energy absorbing modules having edge flanges that define at least one elongated female trough, wherein the female trough includes longitudinal ribs, the edge flanges also defining an elongate male lug that is adapted to engage a female trough of an adjacent module.
