Attached are two diagrams of generic leaf springs, made using multiple
layers of spring steel. If you replace the flat bars by a couple pieces
of piano wire (which is tempered spring steel) you can achieve the same
effect with readily available materials. The exact number and size of
wires needed depends on the desired load to be absorbed. If you place
two such springs linearly behind the bumper, it will absorb loads
regardless of the direction of impact.
