    Abstract: The two mediately positioned cantilevered rings of four spaced concentric rings of resilient spring material are joined to adjacent rings at diametrically opposite locations by resilient bridges to form a leaf spring structure having inner and outer support rings bridged to respective anchor sides of adjacent inner and outer mediately positioned cantilevered rings whose free ends are joined by a resilient bridge. In one embodiment the inner and outer rings are mounted respectively by a slipring assembly to the fixed reference and the suspended inertial mass to allow relative rotation between each of them and the leaf spring structure when subjected to tortuous forces.
