| 摘要 |
The present invention relates to energy absorbent material and in particular, to relatively thin and lightweight energy absorbent material comprising two or more frustoconical cones formed from an elastomeric material in which the cones have the property that, under impact, they collapse inwardly and thereby optimize the absorption of impact energy. The two or more frostoconical cones have each an inner angle of from 62° to 85°, a wall thickness of from 0.8 mm to 1.8 mm and a height of from 10 to 20 mm. |
