Abstract
Abstract Impact-absorbing safety matting systems include a mat for children's play areas. All systems have a surface layer with a bottom and outer edges, an array of air-filled cells affixed to the bottom of the surface layer, ribs extending from the bottom of the surface layer for defining the array of air-filled cells, sealer and aggregate spread over the surface layer and a base immediate to edges, and median ribs extending a shorter distance from the bottom of the surface layer than the defining ribs in order to give added support against a strong blow striking the surface layer and the array of air-filled cells affixed thereto. Each children's play mat is characterized by a void area left in place of at least one median rib in order to facilitate cutting through the surface layer, a second layer of sealer spread under the array of air-filled cells and above the base in order to hold the array of air-filled cells in a substantially vertical orientation, and a sloping outer edge surrounding all sides in order to prevent the escape of air therefrom. In lieu of the sloping outer edge, a beveled outer edge may be provided in order to facilitate attachment to and placement in a recess in the base so that an integrated installation is obtained.
