  • Patent number: 4838609
    Abstract: A preferred form of a swing couch (10) is disclosed including a frame (18) suspended by a flaccid member (22) secured to ends (20) of the frame (18) and extending around and being supported by a pulley (24). Frame (18) can be adjusted between vertical to horizontal positions and held by clamping the flaccid member (22) adjacent pulley (24). Upholstery material (12) is draped between and secured to upper and lower horizontal cross beams (14, 16) of the frame (18) by having the free ends of the material (12) clamped to the beams (14, 16) while being wrapped around at least two corners of the beams (14, 16) to allow minimal adherence securement. A seat support (38) is adjustably suspended generally parallel to and slightly below the lower beam (16) by flaccid members (40) extending from ends (20). A back support (26) is pivotally mounted within the frame (18) about its upper edge by an axis which is parallel to and adjacent the upper beam (14).
