Abstract
Abstract A seating unit includes a seat, a back, a base, and a motion control having a plurality of flexible supports for operably supporting the seat and back on the base. The flexible supports are movable in a generally fore-to-aft direction but stiff in a generally vertical direction, and further the flexible supports have end sections projecting generally outward from said base for operably engaging the seat and/or back, so that when the flexible supports flex in the fore-to-aft direction, they provide for directed movement of the seat and/or the back. In one form, the flexible supports form leaf-spring-like beams with resiliently bendable ends that flex in a slightly angled fore-aft direction to provide a predetermined synchronized path of movement of the seat and back.
