' 4 Claims. (01. 155-181 My invention relates to seats, and more particularly to railway car seats, airplane seats, automotive or other vehicle seats, or to furniture seats.

One object of the invention is to provide comfortable seat and reclining back structures consisting largely of wire construction to obtain compact structures of light-weight and maximum strength.

Another object is to provide a back structure of hollow formation open at the rear to provide knee room, so that a greater number of seats may be arranged in one or more rows in a vehicle of given size without discomfort 'to'the passengers.

A further object is to combine a seat structure and a back structure including'a number of coacting structural features to effect a floating support, whereby the seat and back structures may compensate for and accommodate themselves to movements of the occupant'and the vehicle.

Other features will hereinafter appear and in order that the invention may be fully understood. reference will now be had to the accompanying drawings, in which: I I

Fig. 1 is a vertical sectional view of the combined seat and backstructures taken on line 1-4 of Fig. 2, theback structure being in raised position in Fig. 1 and lowered in Fig. 2.

Fig. 2 is a'top plan ,view of the-seat and back structures, respectively, with portions of the latter broken away and most of the-upholstery removed therefrom;

Fig. 3 is a fragmentary perspective view of one end of a bridge structure for reinforcing the seat structure.

Fig. 4 is a detail perspective view of a clip inextended position ready for use.

structures, respectively.

Referring more particularly to the structures disclosedby Figs. 1 to 8, inclusive, 2 in general' designates the seat structure which has a lower frame comprising two side members 4 4, and transverse front and rear members 5 and 8 uniting. the ends of the sidemembers 44, respectively. Each member of'the seat frame is of composite constructionFigs. 1 and 6, includin 2 v a wooden or other tacking core '9 incased in a metallic sheath I9, having a series of spaced apertures l4 through which tacks 16 may be driven into said tacking core 9, to secureupholstery I8 thereto. The rear portions of the respective side members 4 are turned upward and terminate in hinge members 20 which are operably connected to hinge members 22 on the lower forwardly bent portions of the back structure 24, so that the latter may be swung forward to a folded position upon the seat structure 2, or backward toa reclining position. The back structure 24 may be supported in. raised or inclined position, orv at any point therebetween by any suitable means such, for example, as themea'ns best disclosed by Fig. 2 of my, Patent No. 2,430,604, issued November 11;;1947. i r 7 I The frame of the seat structure 2 is surmounted by a superstructure ,26 of wire construction to obtain ample strength with a minimum of weight. As shown byFigs, l and 2, the upper portion of the superstructure 26 includes a plurality of are bent downwardly into approximately semi-. I

longitudinal strands, 28 which extend the full length of the seat. ,Each strand is bent transversel y midway between its ends and then bent forwardly to provide a pair of parallel strands 29.. The transverse portion forms a hinge member '39 for apurpose which will hereinafter appear. The parallel strands 29 extend forwardly'beyond the front frame member 6 of the seat structure 2 and circular form, as'indicated at 32, then .bent upwardly as indicated at 34, Fig. 1, then rearwardly substantially cylindrical form disclosed by. Fig. 5,

The curved front "portions 32 of the strands provide a comfortable support for the knees of the occupant of the seat, while the upwardly bent portions 34 cooperate with the curved portions 32 in supporting the forward portion of the superstructure 26. Iheupwardly bent portion 34 of each strand 29 is assisted in sustaining the front portion of the superstructure 26 by a rearwardly curved resilient reinforcing member 38, the lower end of which is fixed in the front frame member 6, while its upper end is secured to therespective strand 29 by the clip 36. The rear portions of the strands 29 are yieldably supported by forwardly curved resilient members 40 secured at their lower ends to the rear frame member 8 of the seat structure 2, and secured at their upper ends to the strands 29 by clips 42, respectively' The intermediate portion of each strand 29 is yieldably supported by a resilient member M of wire construction bent approximately into elliptical form. The lower ends of each resilient member i i are fixed in a transverse brace 4'6, and their upper portions are fixed to the respective strands 29 by means of clips 4?. Spring elements 38 cooperate with the respective resilient members 45 in yieldably supporting the intermediate portions of the associated strands 28. Each resilient element E8 consists preferably of a strip of resilient sheet metal, the ends of which are interlaced with a wire 5% bent in zigzag form extending approximately the full length of the associated parallel strands 29,

A zigzag wire 5G is arranged between the strands 29 of each pair and secured at its bent lateral portions to the associated strands by means of clips 52. Each zigzag wire as rein= forces the associated pair of strands 29 and assists in retaining the latter in parallelism. The zigzag wires 58, however, permit the strands as to move longitudinally to a limited extent, so that the superstructure 26 may move forward and backward with a floating like motion. The zigzag wires 58 are assisted in preventing the pairs of parallel strands 29 from spreading apart by transverse wires 54 which extend approximately the full width of the superstructure 25 and are secured to the strands 29 by means of clips 56. The curved ends of each resilient member a l, like the parallel strands 29, are reinforced by wires 58, bent into zigzag form and secured at their bent lateral portions to the bridges by clips 60. and rear ends, respectively, of the superstructure 26 may be likewise reinforced with zigzag wires 54', to which they are secured by clips 552.

The clips 35, 42, 41, 52, 56, 61!, and 62 are preferably like the clip disclosed by Figs. 4 and 5. As shown by Fig. 4, both ends of the clip are bent at right angles to the main body portion into V-shaped lugs 64 adapted to interlook as shown by Fig. 5, when the clip is bent into cylindrical form while being applied to the associated wires. The clips are rendered noiseless by fabric or other suitable lining 66, to elirninate squeaks and other noises in the event one or more clips should become loose and scrape against the associated wires.

As disclosed by Figs. 1 and 2, the back structure 24 is somewhat similar in construction to the seat structure 2 and comprises a hollow rectangular frame 68, including side members 19 united by upper and lower end members 72 and M, respectively. The side and end members i0, 72 and M are approximately of rectangular cross section as shown by Figs. 1 and 7 and comprise tacking strips encased in metal sheaths iii, the longitudinal margins 80 of which are spaced apart to permit tacks 82 to be driven into the respective tacking strips for the purpose of holding the upholstery H3 in place. One side of each sheath #8 has a longitudinal bead 3 with perforations 85, for a purpose which will presently appear.

The front portion of the back structure 24 includes longitudinal strands 85, each of which is bent transversely midway between its ends to provide a pair of upwardly extending parallel strands 8! and a hinge member 88. members 88 are operably connected to the associated hinge members as by split coupling members 99, which are bent into cylindrical form around the hinge members 3!} and 88, respec- The curved portions 38 and A l at the front The hinge tively. The upper ends of the parallel strands 31 extend above the back frame 68 and are then curved rearwardly and downwardly and secured at their ends in the perforations of the bead 84 on the upper transverse back member '12. The upper curved portion of each strand 8'! is reinforced with a wire brace es secured at its ends to the strand by clips 536, while the lower portion of each strand 8? is reinforced by an arched wire brace 98 secured at its forward end to the associated strand by a clip H39 and at its rear end in a perforation 85 of the bead 84 of the lower transverse end member 714.

Each pair of parallel strands 3? is reinforced by a zigzag wire it secured at its bent lateral portions to the strands by clips it'd. The parallel strands 5?, are further reinforced with resilient elements 4 3, which have their ends interlaced with the zigzag wires EM, respectively. If desired the strands 8? may also be reinforced with transverse wires 54.

By providing an open rectangular frame 53 for the back structure 2 as disclosed by Fig. 1, it is apparent that a greater number of seats may be arranged in a row in a vehicle of given size than with ordinary seats, as the knees may be extended into the hollow back structures '24 without inconveniencing the passengers, and the lower transverse member M may be used as a footrest.

Any suitable upholstery may be employed. That disclosed by Figs. 1 and 2 is in one continuous piece so that the back portion will move up and down with the seat portion and thus avoid disarrangernent of occupants clothes.

If desired the seat may be equipped with legs and arm rests, or it may be placed in an auxiliary support, not shown, provided with such equipment. 7

From the foregoing specification and drawings, it will be understood that I have provided a combined seat and back structure possessing the advantages above pointed out, and while I have shown and described two forms of the'invention it is apparent that other forms and modifications may be made which fall within the scope of the invention as claimed.
