  • Patent number: 4244622
    Abstract: A hanging chair comprising a plurality of flexibly attached crosspieces adapted to conform to the shape of the person sitting therein. A plurality of crosspieces are arranged in a parallel, slightly spaced, array. A plurality of short contour control boards are positioned with one end filling the space between the crosspieces near the crosspiece ends. A body cable is threaded through aligned holes through the crosspieces and first ends of the contour control boards therebetween. The body cable is fastened in a firm but flexible manner at each end. A hanging cable is threaded through holes in the other end of said contour boards (which are preferably longer near the edges of the crosspiece array and shorter near the center) and extended up to an overhead support. Since the second ends of the contour boards are not kept apart by intermediate crosspieces as are the first ends, the second ends move together, forming a rounded contour in which a person may be comfortably seated.
