US Patent 7979918 Protective covering

A protective covering with a hard outer layer and a soft inner layer. The hard outer layer comprises a plurality of substantially rigid shape-retaining and interworking tiles anatomically conformed to a contoured object. The outer layer has sufficient flexibility to adjust its conformity to the object as the object's contour changes. The soft inner layer comprises a plurality of impact absorbing units. The protective covering provides impact resistance and is designed to remain securely in place and protective of the object even when the contour of the object changes.
