  • the seat embodying the invention comprises a seat base 10 and a seat back 11 that may be fixed or pivoted relative to one another by appropriately mounting their frames in accordance with well-known construction.
  • Each of the seat base 10 and seat back 11 is of generally similar construction.
  • the seat base 10 comprises a frame 11 including spaced siderails 13.
  • the seat back 10 further comprises a spring assembly 14 that is resiliently mounted on the rails 13 by sinuous spring elements 15, as presently described (FIGS. 2 and 3).
  • Spring assembly 14 comprises spaced longitudinally extending wires 16 of oil-tempered steel having a paper wrapping l7 and spaced transversely extending wires 18 of oil-tempered steel.
  • Wires I8 include intermediate portions 19, the ends of which are wound around the wires 16 (FIG. 2A) and extend in a free manner as at 20 at an acute angle to the general plane of the intermediate portions 19 (FIG. 3).
  • the free ends of portions 20 are attached by a single loop about additional longitudinally spaced wires 21 of paper cord or the like.
  • the spring elements 15 comprise a plurality of rectangular loops forming one or more V-shaped sections and have varying configurations at their longitudinally spaced connection to the intermediate wires 16.
  • the elements at the middle of the seat have the configuration such as in FIG. 3 comprising rectangularly shaped loops including a first loop 22 that is hooked into a clip 23 on the frame rail 13, a second loop 24 extending upwardly and inwardly, a generally horizontal third loop 25, an upwardly and outwardly inclined fourth loop 26, an inwardly and upwardly inclined fifth loop 27, and an upwardly and outwardly inclined sixth loop 28.
  • a U-shaped clip 29 is provided on the end of the spring element 150 and extends generally vertically with its plane at a right angle to the plane of the loop 28 to engage the wires 16.
  • the sinuous spring element 15a thus comprises four generally V-shaped portions, one of which forms an obtuse angle as at 30, the others of which form acute angles as at 31, 32.
  • the sinuous element 15b at the front end of the seat is shown in FIG. 4 and is generally similar and includes a first horizontal loop 33, a second upwardly and inwardly inclined loop 34, a third upwardly and outwardly inclined loop 35, a fourth upwardly and inwardly inclined loop 36, and a fifth generally horizontal loop 37 having a clip 38 thereon for engaging the wire 16.
  • This spring element thus forms three V- shaped portions 39, 40, 41, each of which defines an acute angle.
  • the spring element 150 at the rear end of the seat base is similar except that it comprises a lesser number of loops as shown in FIG. 5 and 6 including a first loop 42, a second upwardly and outwardly inclined loop 43, a third generally horizontal loop 44 having the clip 45 thereon engaging the wire 16.
  • the spring element 15c is made of a single piece of wire such as shown in FIG. 7 which is formed into generally rectangular loops including transverse torsion bars 46, 47, 48 and 49 connected by longitudinally extending bars including a curved bar 50, straight bars 51, 52, and a U-shaped portion defining the clip 45.
  • the sinuous element is bent to proper shape by twisting about transverse bars 47, 48 and 49 as well as about a connecting bar 52 that connects the loop 45 with the transverse bar 49.
  • the arrangement is adapted to hook onto an inclined portion 54 of the base rail 13 as shown in FIG. 6 to connect to the wire 16.
  • the seat back 11 includes a frame 59 having spaced siderails 60, a spring assembly 61 which is resiliently supported on the rails 60 by a plurality of longitudinally spaced sinuous springs 62.
  • the spring assembly 61 comprises a plurality of spaced longitudinally extending oil-tempered steel wires 63 that are wrapped with paper 64 and a plurality of closely spaced tranversely extending oil-tempered steel wires 65, each of which comprises an intermediate portion 66.
  • the wires 65 are wrapped around the wires 63 and have free ends 67 extending upwardly and out wardly to form an acute angle with the general plane of the intermediate portions as shown in FIG. 9.
  • Spring assembly 61 further includes a wire-wrapped longitudinally extending intermediate wire 68, the paper of which is pierced by the wires 65, and paper wire elements 69 about which the ends of the free portions 67 are looped.
  • each of the sinuous elements 62 is of varying configurations depending upon the degree of resiliency and distance that the portion of the spring assembly is to be mounted with respect to the frame.
  • the spring element 62a at the intermediate portion of the seat comprise a first loop 70 that has a transverse bar 71 that clips through a retaining clip 72, a second loop 73 forming an obtuse angle with the loop 70, a third loop 74 extending outwardly and away from the frame and forming an acute angle with the loop 73, a fourth loop 75 forming an angle with the loop 74 and also extending outwardly, and a clip 76 forming a right angle to the plane of the loop 75 and engaging the wire 61.
  • the sinuous element at the base of the seat back is generally similar and comprises a first loop 78, a second loop 79 extending outwardly away from the frame and inwardly with respect to the seat and at an obtuse angle to the loop 78, third, fourth and fifth loops 80, 81 and 82 lying in the same general plane and extending outwardly and away from the frame, and a clip 83 engaging the wire 63.
  • the sinuous elements are made of generally rectangular loops. Thus, for example, the sinuous element shown in F168.
  • 11, 12 and 13 comprises a single wire including transverse bars 84, 85, 86, 87, 88 and 89 connected by a curved longitudinal wire 90, straight longitudinal bars 91, 92, 93 and 94, respectively.
  • the clip 83 is connected to the transverse bar 89.
  • the foam material may be cast about the spring assemblies with the free portions entirely embedded in the foam material, the outer configuration of the foam material simulating the final shape of the seat.
  • a portion of the spring assembly includes wire elements 66' which terminate at the wire 63 and extend upwardly to form a support for the foam material which serves as a headrest formed integrally with the seat. It should be understood that upholstery material or trim is provided overlying the foam material in accordance with wellknown practice.
  • a spring assembly comprising a pair of longitudinally extending wires
