RESISTIVE SUPPORT MECHANISM FOR A CHAIR INCLUDING USER FEEDBACK
First Claim
1. 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 said resistance cartridge undergoes movement relative to the base and applies a resistive force on the base as the mounting surface undergoes said one or both of rotational and tilt movement;
wherein the mounting surface and said resistance cartridge are connected by at least one sensor for measuring one of forces applied by said mounting surface on said resistance cartridge, movement of said mounting surface with respect to said cartridge and/or acceleration of said mounting surface with respect to said cartridge.

16. A chair having a seat, a base, and a motion support mechanism joined to the base and the seat, wherein the motion support mechanism is joined to the seat by a plurality of load sensors;
- said motion support mechanism providing resistive support to the seat as the seat undergoes one or both of rotational and tilt movement relative to the base, the motion support mechanism comprising;
a support bearing connected to the seat and to the base which permits one or both of tilting and rotational motion of the seat relative to the base;
a pivot ball fixedly attached to a portion of the base; and
, a resistance cartridge fixedly connected to the seat such that said resistance cartridge undergoes movement relative to the base and applies a resistive force on the base as the seat undergoes said one or both of rotational and tilt movement;
wherein said resistance cartridge includes;
a cartridge housing; and
, a resilient member in contact relation with said pivot ball and with a wall of said housing such that said resilient member is compressed by the relative movement between said resistance cartridge and said pivot ball to thereby provide the resistive support to the seat.
- said motion support mechanism providing resistive support to the seat as the seat undergoes one or both of rotational and tilt movement relative to the base, the motion support mechanism comprising;
