ABSTRACT:
A compression spring formed of an elastomer having a ratio of plastic strain to elastic strain that is greater than 1.5 to l and formed into a spherical body having cone frustums at each end to provide for a substantially constant spring rate over a major portion of its displacement. The spring is precompressed to overcome the compression set characteristics of the elastomer and to orient its molecular structure. The spring is particularly useful as a bumper spring for an automotive vehicle.
