ABSTRACT:
A shock-absorbing device, such as a vehicle fender, comprises an assembly of interconnected elastomeric cells. The cells are arranged to extend at right angles to the forces to be absorbed and have a polygonal cross-section. The cells are formed so that, in absorbing forces, the device is initially resiliently deformed, then deformed by buckling of the cell walls and finally compressed.
