Patent ID: 7234153

Claim:
A vibration damper for supporting vibration sensitive items in relation to a base, said vibration damper comprising springs in the form of fixed bent wire pieces, each wire piece being built up of a number of twisted strands, where each bent wire piece is contained approximately in a single plane, wherein the vibration damper consists of two springs arranged in two mutually perpendicular planes, respectively, of which one plane is parallel to the base, where a first of said two springs is fastened to the base and a second of said two springs is fastened to said first spring and to the vibration sensitive item, said second spring being fastened to said vibration sensitive item at a point that is remote from where it is fastened to said first spring, whereby the two springs are interconnected in said two mutually perpendicular planes, and wherein the bent wire pieces form approximately a semi-circle, or the two bent wire pieces form a full circle and a certain overlap with respect to mounting, or that two bent wire pieces arranged side by side are made continuous, wherein each spring absorbs the loads by rolling or torsion in each of the bent wire pieces influenced.
