Patent ID: 8061767

Claim:
A seating system comprising, in combination: a left seat, a right seat, a base, a first elongate flexible support member having first and second longitudinal ends, the first flexible support member pivotally connected to the left seat by a first joint at or adjacent to the first longitudinal end and to the base by a second joint at or adjacent to the second longitudinal end, and a second elongate flexible support member having third and fourth longitudinal ends, the second flexible support member pivotally connected to the right seat by a third joint at or adjacent to the third longitudinal end and to the base by a fourth joint at or adjacent to the fourth longitudinal end, wherein: the left and right seats are adapted to be simultaneously sat upon by a single human, the second joint allows independent rotation of the left seat about a first axis, the first axis being a straight line in a vertical direction that intersects the second joint, the fourth joint allows independent rotation of the right seat about a second axis, the second axis being a straight line in a vertical direction that intersects the fourth joint, a “lateral” direction meaning a direction that is parallel to a straight line segment that intersects the second joint and the fourth joint, and a “vertical” direction and a “front/back” direction each being defined by a frame of reference that is fixed relative to the seating system as a whole, and has three axes, being vertical, lateral and front/back, respectively, the lateral axis being in a lateral direction, which three axes: are perpendicular to each other, and are oriented so that, when the lateral axis is horizontal from an external observer's point of view, the vertical axis is vertical from the external observer's point of view, the external observer's point of view being oriented so that up and down are along the direction of maximum gravitational force being exerted on the seating system.
