摘要： Compositions and designs useful for fabricating safety cushion and mat assemblies which have effective protection against injuries to persons falling from a height of up to twelve feet are disclosed. The rubber anchor composition has a shore hardness of about 73 and comprises a natural rubber, a processing aid agent, a plasticizer, a filler, an antioxidant, an antiozonant, an activator, an accelerator, a vulcanizer, an inhibitor and optionally a colorant or a whitener. Moreover, the rubber anchor comprises a rounded head portion with a diameter of about 1.5-2.2 inches and a thickness of about 0.15-0.5 inches; a bolt portion of about 3-6 inches in length, and a diameter of about 0.4-0.8 inches, preferably the bolt portion further has indentations. In addition, preferably a metal washer is embedded in the bottom of the rounded head portion to provide further anchoring support to prevent the impact attenuation safety cushion and system from being pulled up from the ground.Methods of fabricating the safety cushion, mat assemblies and securing anchors described above improves the fabricating process so that larger pieces of safety cushion can be molded and that the composition material does not stick to the mold thereby increases production efficiency.

摘要： Compositions and designs useful for fabricating safety cushion and mat assemblies which have effective protection against injuries to persons falling from a height up to seven feet are disclosed. The safety cushion compositions have a shore hardness of about 68, comprises an ethylene/propylene rubber, an activator, an accelerator, a plasticizer, a vulcanizer, a filler, a processing aid agent and optionally a colorant or a whitener. In addition, compositions useful for fabricating a reinforced rubber anchor for securing the safety cushion and mat assemblies to the ground are disclosed. The rubber anchor composition has a shore hardness of about 73 and comprises a natural rubber, a processing aid agent, a plasticizer, a filler, an antioxidant, an antiozonant, an activator, an accelerator, a vulcanizer, an inhibitor and optionally a colorant or a whitener. Methods of fabricating the safety cushion, mat assemblies and securing anchors described above improves the fabricating process so that larger pieces of safety cushion can be molded and that the composition material does not stick to the mold thereby increases production efficiency.
