Energy absorbing apparatus for securing to a rounded object, in particular apparatus (11) for absorbing energy of an errant vehicle impacting a rounded roadside hazard (13), such as a pole, comprises an expanded cell type sheet which consists of an array of side by side tubular cells (19) arranged with their axes perpendicular to the median plane of the sheet. This cellular sheet is designed to be at least partially wrapped around the rounded object (13), whereby the cell configuration is distorted so that the cross-sectional areas of the cells (19) are smaller nearest to the rounded object (13) and larger away from said rounded object. The cells (19) of the sheet may be filled with a deformable, energy absorbing material such as foam plastic, and a plurality of said cellular sheets may be used in a stacked relation, offset from each other so that upon impact the walls of overlying arrays of cells cut into each other. …<??>For use with a non-rounded hazard, an adaptor including a projecting semi-circular portion is interposed between said cellular sheet or sheets and the hazard. |
