Abstract
A spring for a seismometer for suspending one body relative to a fixed reference point within a housing including an outer ring and an inner ring interconnected by a plurality of arcuate legs. Each leg has an inner and an outer edge which may be defined by a plurality of arcs of different radii and distinct centers. The plurality of arcs further divide each leg into an inner section and an outer section of approximately equal length, and a middle section of substantially constant width and thickness. The spring provides an improved spurious resonance over the prior art springs as well as having an improved useful life.
