<p>A controlled relative motion system permitting a controlled motion member to move with respect to the base member, has a base support, an output structure, and a fork arc structure having a pair of arc output ends with the output structure rotatably connected to a corresponding one of the pair of arc arms adjacent the arc output end thereof to rotate about an output structure rotation axis. A fork arc structure rotary support has each remaining base end of the pair of arc arms joined thereto and is connected to the base support to rotate about a fork axis intersecting the base plane at a suspension angle. An output structure force imparting means is connected between the output structure and an operating one of the pair of arc arms. A fork arc structure force imparting means is connected between the base support and the fork arc structure.</p> |
