Abstract:
1. A recoiling energy absorbing system comprising an impact-receiving outer shell that is exposed to percussive impact, the outer shell being selected from the group consisting of floors, walls or ceilings above or surrounding a playing surface, an ice rink, 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, artificial turf, a military blast mat, industrial flooring for industrial, retail or domestic home use, and an automotive application, a single absorbing layer positioned between the outer shell and a continuous planar lower reaction surface, the layer having a flexible curvilinear wall that extends from the upper basal layer convergingly away from the outer shell towards a lower basal layer that defines an end of the associated frustoconical energy absorbing unit and is juxtaposed with the continuous planar lower reaction surface so that in response to normally oriented or oblique impacting forces substantially an entire portion of the lower basal layer remains in contact with the lower reaction surface, each lower basal layer being the terminal end of the curvilinear flexible wall; 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 without rupture and recoiling non-destructively after impact to or towards an undeflected configuration.
