Abstract
The spring includes a tubular elastomeric body, preferably rubber, and a coil spring embedded in and bonded to it. The coil spring controls the occurence of symmetric bulging instablity in the body under axial load conditions. This bulging instability occurs sequentially along the length of the body between adjacent coils of the coil spring until it assumes the form of a continuous coil of elastomer.
