发明名称 Seating
摘要 Among other things, a seat includes a back-supporting surface; and a seating surface movable along a path toward and away from the back-supporting surface. At least part of the back-supporting surface is movable to enable a lower portion of the back-supporting surface to move substantially along the path.

主权项 1. A seat comprising: a stationary base to rest on a floor; a seating surface supported on the base, a back-supporting surface supported on the base; and a rotational mechanism that enables the back-supporting surface to rotate about an axis that is higher from the floor than is the seating surface, the seating surface being movable on the base along a path of motion toward and away from a vertical plane that contains the axis, the axis having an original starting position when the seating surface is not occupied, the axis being movable from its starting position along a path of motion in response to a force exerted on the back-supporting surface when a sitter is sitting on the seating surface, at least part of the path of motion of the axis not tracking the path of motion of the seating surface, and simultaneously the seating surface being movable on the base along the path of motion toward and away from the vertical plane that contains the axis in response to a force exerted when the sitter is sitting on the seating surface, at least part of the motion of the seating surface toward and away from the vertical plane being independent of any component of motion of the axis that is aligned with the path of motion of the seating surface, at least one location on the back-supporting surface following a path of rotation about the axis, the path of rotation having a radius centered on the axis, the radius of the path remaining unchanged during at least a portion of the motion of the axis.
