  • Patent number: 4846450
    Abstract: A furniture wedge seat comprising a wedge shaped frame including a relatively short front rail, a relatively long back spring rail, and converging (back-to-front) side rails. A spring assembly including primary load bearing spring elements is mounted in the frame with these primary elements disposed parallel to each other. Bracketing the primary spring elements are secondary cushion bearing spring elements. The primary and secondary elements are interconnected by tie wires.

  • Patent number: 4815717
    Abstract: A seat spring assembly for upholstered furniture incorporates an inverted torque arm adjacent the back rail of the furniture frame. The torque arm is formed upwardly out of the body of a sinuous spring band which descends from its crown closer to the front rail, in a continuous curve, to lower end of the torque arm at a point below the level of the top of the back rail. The torque arm is connected, from its upper end to the back rail, by translatory means which include a generally horizontal link.

  • Patent number: 4586700
    Abstract: A furniture seat base which employs a series of front and/or back torsioned sinuous spring bands. Predetermined patterns of torsioned bands produce an interaction which generate spring dynamics designed to produce a seat unit which may be sat upon from the front, back, sides, or corners with excellent comfort characteristics. The bands are selectively supported adjacent the rails to obviate objectionable "lean-out.

  • Patent number: 4396225
    Abstract: A cushion base and ottoman assembly in a recliner. The assembly has a front rail normally with a relatively wide upper surface. A vertically resilient jaw unit is mounted on the upper surface of the front rail, the jaw unit having a fish mouth configuration opening forwardly. Upholstery material is drawn over the cushion base assembly whereby a recess is formed below the jaw unit and in front of the front rail. The ottoman nests in this recess when retracted. When extended the assembly continues to resiliently support a cushion out to its front edge.

  • Patent number: 4364547
    Abstract: A family of improved seat base assemblies for furniture seats and automotive seats and the like. A cushion base means, which might comprise a plurality of sinuous spring bands, a wire mesh unit, or chord rubber webbing or the like, is mounted between the front, back, and side nails of the seat frame. Rail connecting means connect at least the back rail to the cushion base means. The rail connecting means provides vertically resilient support to the cushion base means which increases as the cushion base means moves downwardly under load. In one form of the invention rail connecting means connect a wire mesh unit to all four of the rails, around its entire periphery.

  • Patent number: 4352524
    Abstract: An improvement in a fastening assembly for upholstery material on the rail of a metal frame in furniture seats or the like. The frame rail includes an outer member and a member extending inwardly of it along one of its edges; i.e., a flange formed on the web of a channel, for example. A first flexible fastening element is secured to said flange and has a plurality of tiny loops formed in it. A second flexible fastening element is secured to the periphery of the upholstery material and has a plurality of tiny gripping fingers formed in it. The fingers are pressed perpendicularly into the loops, causing them to interlock. The upholstery material drawn tight around the frame exerts stress on its fastening elements substantially only in shear.

  • Patent number: 4303232
    Abstract: A coil seat spring assembly wherein spring coils are mounted on a plurality of sinuous spring bands extending between the front and back rails of a furniture seat frame. The axes of the coils are substantially vertical. The coils on each band are clamped to each other and to adjacent coils and adjacent bands at their uppermost coil turns and at their lowermost coil turns. The coils are approximately two-thirds the axial length of conventional coil springs.

  • Patent number: 4247089
    Abstract: A seat spring assembly having sinuous spring bands wherein the outermost band adjacent a side rail is provided supplemental resilient resistance to deflection by a combination of a trust member and a key member. As a result, a uniform spacing can be maintained between the bands across the entire seat frame.

  • Patent number: 4228991
    Abstract: A seat spring assembly comprising the combination of a sinuous spring band connected between the front and back rails of a furniture seat frame and a rectangular loop, zig-zag wire spring unit rigidly secured to the top of the spring band. A substantially horizontal cushion support section of the unit extends between the front rail and a point approximately three-quarters of the way from front to back rails. The unit introduces torquing compression to the band near the front rail and in the body of the band away from the back rail as a subject is seated.

  • Patent number: 4157173
    Abstract: A rail connector and improvement in seat base support assembly. The connector takes two basic forms. In the first a pre-stressed, close wound coil, disposed either transversely or longitudinally of the connector, is effective to continuously bias the seat base support means upwardly. In the second a cantilevered, curved spring arm serves the same purpose. The connector may be configured to reach into the body of a sinuous spring band, for example, and define a torque arm in the band, at the back rail. All forms are applicable to wire mesh, chord rubber webbing, flat steel bands and sinuous, both arced and dearced.

  • Patent number: 4157172
    Abstract: A rail connector and improvement in seat base support assembly. The connector, in its simplest form, comprises a generally V-shaped body fabricated of spring steel wire, the body having diverging side legs and then rail attachment and spring attachment legs extending in opposite directions from the free ends of the side legs. The rail-attachment leg or legs may be fixed to the rail, pivotally attached thereto, or attached in articulated fashion. The spring-attachment leg may be pivotally connected to the seat base support means or, particularly where a sinuous spring band is involved reach up into the band. Varying the side leg dimensions varies the seat base performance.

  • Patent number: 4070124
    Abstract: A rail attachment assembly for attaching an end of a sinuous spring band to a steel rail. A vertical or a horizontal flange of the rail is apertured or cut-out to facilitate passage of an anchor link for band element. The aperture or cut-out is elongated along one axis to permit pivotal movement of the link or band through a substantial arc without interference.

  • Patent number: 4055865
    Abstract: A rail attachment assembly for attaching an end of a sinuous spring band to a steel rail. A vertical flange of the rail is provided with pairs of longitudinally spaced apertures to facilitate passage of anchor links or band elements. The steel rail section between the apertures in each pair is deformed inwardly of the flange to permit seating of the heavier gauge band segment or the lighter gauge link segment for rotation about a fixed axis. Where either a link or a spring is employed, noise, grinding and squeeking normally associated with uncontrolled vertical and/or lateral motion and travel of the link or springs; i.e., "wandering", is obviated.

  • Patent number: 4037829
    Abstract: A rail anchor and attachment assembly for securing the end of a sinuous spring band to a curved frame rail in a furniture frame. The anchor is a pin fabricated from heavy gauge wire. It comprises a vertical anchor leg seated against the back surface of a frame rail and depending from a horizontal attachment leg. An attachment hook on the free end of the attachment leg receives a spring band, a helical connector spring or some other form of band connector, to form an attachment assembly joining the band to the rail.

  • Patent number: 3969793
    Abstract: An attachment clip and assembly for attaching the end of a sinuous spring band to a wood furniture frame rail without the need for any nails or staples whatever and without any hammering or driving to engage the anchoring tangs. The clip has an anchor leg and an attachment leg. Tiny, sharp, upwardly inclined anchor saw-teeth plow in against the outer surface of the rail and automatically embed in the surface when pressure is applied by the spring band secured to a hook on the free end of the attachment leg. Anti-backoff means in the form of anti-backoff feet bearing against the inner surface of the rail and/or outwardly inclined anti-backoff tangs under the attachment leg serve to prevent the clip from becoming unseated when spring tension is released and outward shock loading applied to the clip.
