  • Resistive support mechanism
    Patent number: 9211013
    Abstract: A motion support mechanism, for example for a chair, 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 includes 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 pivot ball sized fixedly attached to a portion of the base, and, 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 one or both of rotational and tilt movement.
