Abstract
A flexure bearing “planar” spring that can spring multiple, independently reciprocating bodies, such as springing each body to a third body or springing a first body to a second body and springing the second body to a third body. A primary arm set of primary spring arms are separated from each other by openings and extend inwardly from a peripheral frame along a non-radial primary path progressing inwardly toward a central axis and angularly about the central axis. A secondary arm set of at least one secondary spring arm extends along a non-radial secondary path progressing radially and angularly about the central axis. Each secondary arm is interposed in an opening between the primary arms allowing the primary arms and the secondary arms to pass by each other through the openings without interfering with each other.
