Abstract
A stabilized oscillating chair has a base means, a column extending upwardly from the base, a seat assembly having bottom, back and arm rest portions, and a yoke assembly supported on the upper portion of the column for roll rotation. The yoke assembly is pivotable for yaw rotation relative to the base, and extends under the arm rests for pivotal connection for pitch rotation of the chair assembly. Roll pivot means are provided between the column and the yoke assembly, and pitch pivot means are provided between the yoke assembly and the arm rests. Pitch bias springs are connected with the pitch pivots to urge the chair assembly to normal attitude and have such resilience as to accommodate maintenance of the seat assembly level when occupied. Roll bias springs are connected with the roll pivotal connection to resiliently urge the yoke assembly and chair assembly toward a normal attitude, and are adapted to maintain the chair assembly in normal attitude when unoccupied and to permit it to remain substantially level when occupied.
