Abstract
A resistive motion support mechanism joined to a mounting surface and to a base for providing resistive support to the mounting surface as the mounting surface undergoes one or both of rotational and tilt movement relative to the base, the motion support mechanism comprising: a support bearing connected to the mounting surface and to the base which permits one or both of tilting and rotational motion of the mounting surface relative to the base; a resistance cartridge fixedly connected to the mounting surface such that the resistance cartridge undergoes movement relative to the base and applies a resistive force on the base as the mounting surface undergoes the one or both of rotational and tilt movement. The mounting surface and the resistance cartridge are connected by at least one sensor for measuring one of forces applied by the mounting surface on the resistance cartridge, movement of the mounting surface with respect to the cartridge and/or acceleration of the mounting surface with respect to the cartridge.
