A recoiling energy absorbing system is interpositioned between an outer shell that is exposed to percussive impact and a foundation. An energy absorbing layer with friction lugs is positioned inside the outer shell. The energy absorbing layer includes one or more energy absorbing modules with optional veins and drain holes. At least some of the modules are provided with one or more energy absorbing units that extend from an upper basal layer. At least some of the energy absorbing units are provided with a flexible wall that extends from the upper basal layer. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its undeflected configuration.

1. A recoiling energy absorbing system configured to be interposed between on the one hand an outer layer that is exposed to impact, the outer layer being selected from the group consisting of floors, roofs, walls or ceilings in a playing surface, a hockey arena, a roller blading rink, a gymnasium,
1. A recoiling energy absorbing system configured to be interposed between on the one hand an outer layer that is exposed to impact, the outer layer being selected from the group consisting of floors, roofs, walls or ceilings in a playing surface, a hockey arena, a roller blading rink, a gymnasium, a basketball court, a tennis court, a wall, a racquetball or squash court, a soccer field, a football or hockey or lacrosse field, a baseball field, synthetic turf, ASTROTURF®, a military blast mat, flooring for industrial, retail or domestic home use, an automotive application, and the like and on the other hand a foundation, the recoiling energy absorbing system having: interlocking energy absorbing modules, at least some of the modules being provided with: edges, at least some of the edges having means for interlocking with an edge of an adjacent module, the means for interlocking including energy absorbing units being received by energy absorbing units disposed along an edge of an adjacent module;the one or more energy absorbing units being hexagonally arranged and extending from means for coordinating energy absorbing units having a face that is juxtaposed with the outer layer, at least some of the one or more energy absorbing units having: a frustoconical flexible wall that extends from the face of the means for coordinating away from the outer layer, the frustoconical wall when viewed from above or below having the shape selected from the group consisting of circular, oblong, elliptical or race track;a floor extending between the flexible walls of adjacent energy absorbing units and configured to be positioned adjacent the foundation;the one or more energy absorbing units at least partially absorbing energy generated by an impacting object by the flexible wall bending inwardly or outwardly and recoiling after impact to or towards an undeflected configuration; anda mechanical friction means for impeding slippage extending downwardly from a floor between at least some energy absorbing units toward the foundation or upwardly from a face of the means for coordinating towards the outer layer. 2. The recoiling energy absorbing system of claim 1, wherein the mechanical friction means includes a lug that extends downwardly from the floor of at least some energy absorbing units toward the foundation, and another lug that extends upwardly from the face of the means for coordinating towards the outer layer. 3. The recoiling energy absorbing system of claim 1, wherein one or more of the energy absorbing modules is provided with one or more apertures that serve as drain holes in the face of the means for coordinating, in the floor between energy absorbing units or in both the face and the floor. 4. The recoiling energy absorbing system of claim 3, wherein the plurality of apertures (Y) per module is such that 0≦Y≦5000. 5. The recoiling energy absorbing system of claim 3, wherein at least one flexible wall has a number (X) of breaches therewithin, where 0≦X≦1000, the breaches being formed in an intermediate section of a wall or extend from its lower to its upper perimeter. 6. The recoiling energy absorbing system of claim 1, wherein the means for coordinating lies between energy absorbing units and supports the outer layer, the walls of the energy absorbing units extending away from the outer layer and towards the underlying foundation, the friction means impeding relative motion between the interlocking energy absorbing modules and the outer layer and the foundation. 7. The recoiling energy absorbing system of claim 1, further including a number (M) of veins that interconnect the flexible walls of at least two of the energy absorbing units, where 1≦M≦5000, the veins having a height (H2), wherein H1>H2; and wherein the veins provide structural support to at least one of the flexible walls and coordinate the cushioning of the energy generated by the impacting object throughout a plurality of the energy absorbing units. 8. The recoiling energy absorbing system of claim 7, wherein the energy absorbing units and the veins are interconnected in a grid to facilitate the cushioning of the energy generated by the impacting object throughout the plurality of energy absorbing units. 9. The recoiling energy absorbing system of claim 8, wherein a plurality of the veins extend from the wall of one of the energy absorbing units. 10. The recoiling energy absorbing system of claim 7, further including friction means extending from the floor towards the foundation or from the face of the means for coordinating to the outer layer or both from the floor and the face. 11. The recoiling energy absorbing system of claim 1, wherein the number of edges in a module is 4. 12. The recoiling energy absorbing system of claim 1, wherein the number of edges in a module is >3. 13. The recoiling energy absorbing system of claim 1, further including a rib provided in a flexible wall. 14. The recoiling energy absorbing system of claim 13, wherein the rib is a male rib. 15. The recoiling energy absorbing system of claim 13, wherein the rib is a female rib. 16. The recoiling energy absorbing system of claim 1, further including: an outer layer that is exposed to impact, anda foundation, wherein the interlocking energy absorbing modules are interposed between the outer layer and the foundation.
