ABSTRACT:
A tubular compression spring body made of a thermoplastic elastomeric material has stepped internal and external wall surfaces that are designed so that when the body is compressed, it absorbs a large amount of the compression energy and has a low rebound force. Also, when compressed again after rebound, the compression spring body exhibits excellent repeatability in its force-displacement performance. In different embodiments, the compression spring body may be designed to exhibit various force-displacement performance curves in order to meet various criteria desired by the user, such as maximum energy absorption and/or minimum rebound force.
