Abstract:
A chair comprising:a base;a tilt control mechanism supported on said base; anda seat assembly pivotally connected to said base by said tilt control mechanism;said tilt control mechanism defining a pivot connection connected to said seat assembly and said base about which said seat assembly pivots rearwardly and sidewardly in multiple tilt directions oriented transverse to each other, said tilt control mechanism including first and second surfaces which are disposed in opposing relation, said first surface being stationary relative to said base and said second surface being movable with said seat assembly during pivoting thereof in said multiple transverse directions, said first and second surfaces being radially spaced apart to define a clearance space therebetween, and said tilt control mechanism including a resilient member disposed in said clearance space and extending radially between said first and second surfaces, said resilient member being deformable as said second surface moves relative to said stationary first surface during pivoting of said seat assembly in any of said multiple tilt directions, said resilient member biasing said seat assembly to a neutral position; andsaid tilt control mechanism including an adjustment mechanism connected to said resilient member which adjusts a distance between said resilient member and said pivot connection.
