A multi-tiered recoiling energy absorbing system has an upper impact surface that is exposed to percussive impact. At least one energy absorbing layer is positioned below or inside the upper impact surface. The energy absorbing layer includes one or more energy absorbing modules. At least some of the modules are provided with one or more energy absorbing units that extend from an upper platform. Several of the energy absorbing units are provided with a flexible wall that extends from the upper platform. A lateral reinforcement member secures the energy absorbing units to prevent them from splaying. 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 un-deflected configuration.

1. A recoiling energy absorbing system comprising: an upper impact surface that is exposed to percussive impact, the upper impact surface being selected from the group consisting of a playing surface, walls or ceilings in, around or above a playing surface, a roller blading rink, a gymnasium floor,
1. A recoiling energy absorbing system comprising: an upper impact surface that is exposed to percussive impact, the upper impact surface being selected from the group consisting of a playing surface, walls or ceilings in, around or above a playing surface, a roller blading rink, a gymnasium floor, 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, an artificial turf, a military blast mat, flooring for industrial, retail or domestic home use, walls and floors of military vehicles including helicopters, other aircraft and tanks and automotive load floors; andan energy absorbing system positioned below the upper impact surface, the energy absorbing system having: one or more energy absorbing modules, at least some of the modules being provided witha lower energy absorbing layer positioned adjacent to a lower reaction surface that supports the energy absorbing system, the lower energy absorbing layer having an upper platform,a lower platform that lies adjacent to the lower reaction surface,a lower sidewall extending between the upper and lower platforms andan upper energy absorbing layer positioned between the upper impact surface and the lower energy absorbing layer, the upper energy absorbing layer having a basal layer that interfaces with the upper impact surface,an upper sidewall extending from the basal layer away from the upper impact surface, anda lower platform that interfaces with the upper platform of the lower energy absorbing layer to create an area of contact therebetween for energy distribution so that a space is formed between the basal layer and sidewalls of the upper energy absorbing layer and the sidewalls and lower platform of the lower energy absorbing layer to accommodate deformation;a number (N) of energy absorbing units that are defined between facing sidewalls of the lower and upper energy absorbing layers, where 1≦N≦1000;wherein the one or more energy absorbing units at least partially absorb energy generated by an impacting object by one or more of the sidewalls bending inwardly or outwardly without rupture and recoiling after impact to or towards an un-deflected configuration. 2. The recoiling energy absorbing system of claim 1, wherein the energy absorbing system includes a two-tiered energy absorbing system. 3. The recoiling energy absorbing system of claim 2, wherein each layer of the energy absorbing units compresses towards an underlying layer of the energy absorbing units when the system is subjected to a percussive force so that the stiffness characteristics of the various layers can be altered by the upper energy absorbing layer absorbing more of the percussive blow or deflecting more than the lower layer, or vice-versa. 4. The recoiling energy absorbing system of claim 3, wherein some or all of the energy absorbing units defined between facing sidewalls of the lower energy absorbing layer are supported by a lateral reinforcing member. 5. The recoiling energy absorbing system of claim 4, in which a plurality of energy absorbing units are arranged in a grid. 6. The recoiling energy absorbing system of claim 1, further including a layer of adhesive to adhere the lower energy absorbing layer to the lower reaction surface. 7. The recoiling energy absorbing system of claim 6, wherein the adhesive includes a flexible glue or other adhesive such that the adhesive can bend and flex without rupture as energy is absorbed throughout the energy absorbing layer.
