Abstract:
A seating unit includes a base, a reclineable back, a seat, and a control operably supporting the back and the seat on the base for movement between upright and recline positions. The control includes a pair of flexible support members and a link that combine to operably support the seat and back for synchronous movement on the base upon recline. The flexible support member is stiff in a vertical direction for carrying a combined weight of the one component and of the seated user, but flexible in a horizontal direction to permit a swinging movement of its ends upon recline. The link is rigid and pivoted to the base for movement about a horizontal axis and also pivoted to the one component. By this arrangement, the flexible member and the link move the one component along a defined path during recline of the back.
