Bernstein, Beverly Hills,‘Calif. Application June 23, 1937, Serial No. 149,932 5 Claims. (Cl. 155-179) This invention relates generally to furniture and more particularly to the construction of upholstered furniture in which the seat springs are supported by a farbic sheet secured to the 5 seat frame. This invention is an improvement over the invention disclosed and claimed in Patent No. 2,673,777, issued to me on March 16, 1937. It is a primary object of this invention to pro 10 vide improved yieldable supporting means for the spring supporting fabric sheet used in the seat construction of upholstered furniture whereby the fabric is yieldably supported inwardly of the frame at all times. In this connection it is an 15 object to support the fabric sheet so that the sheet is maintained level when the seat is un occupied and whereby it is allowed to “give” somewhat when the seat is occupied. In order to accomplish this object it is a fur ther object of this invention to provide the chief 20 means of support above the fabric sheet and connected to the frame at points vertically spaced from the bottom thereof but positioned in such a manner that the supporting means will‘not in 25 terfere with the ordinary cushioning springs or with a body occupying the seat. It is also an object to provide secondary support for the fabric sheet in substantially the plane of the sheet whereby the fabric sheet is maintained taut. 30 It is a still further object of this invention to provide means under the fabric sheet which may or may not be attached directly to the frame and to which the ?exible supporting means for the fabric sheet may be attached. 35 It is a particular object of this invention to provide a supporting means for the fabric sheet in furniture of the type indicated which is par ticularly adapted to absorb the initial stress of a body load dropping into the seat and which is 40 adapted to thereafter accommodate itself to the subsequent substantially constant load. These and other objects will be apparent from the drawings and the following description. Re ferring to the drawings which are for illustra 45 tive purposes only: Fig. 1 is an inverted plan view showing a chair bottom equipped with one form of the invention. Fig. 2 is an enlarged sectional elevation taken in a plane represented by the line 2'--2 of Fig. 1. 50‘ Fig. 3 is a perspective View of a supporting plate as shown in the form of the invention illustrated in Fig. 1. Fig. 4 is an inverted plan view showing a chair bottom equipped with another form of the in 55 vention. Fig. 5 is an enlarged sectional elevation taken in a plane represented by the line 5—5 of Fig. 4. Fig. 6 is a perspective view of a supporting plate as shown in the form of the invention illus trated in Fig. 4. Fig. 7 is an inverted plan view showing a chair bottom equipped with still another form of the invention. Fig. 8 is an enlarged sectional elevation taken in a plane represented by the line 8—8 of Fig. 7. 10 Referring more particularly to the drawings, reference numeral l ! generally indicated the seat frame of a chair or the like which comprises side rails l2 and I2’, a front rail l3 and a rear rail It. The chair is provided with legs it of any 15 suitable type. Reference numeral 16 indicates a ?exible spring supporting sheet made of fabric of any suitable material such as burlap or the like. This fabric sheet is secured at three of its marginal edges by tacks i‘! to the bottom of 20 side rails l2 and I2’ and front rail I3. The fabric sheet supports a coil spring assem bly of any conventional type, generally indicated by reference numeral [8. This spring assembly is ordinarily sewed to the fabric sheet and secured 25 to the rails of the frame by means of twine (not shown) and is designed to support a chair base cushion (not shown). The fabric sheet H6 in the form of the inven tion shown in Figures 1 and 2 is shown spaced 30 away from the rear rail of the frame and is pro vided at its rear edge with a rod !9 secured thereto in any suitable manner. As a means of keeping the fabric taut, tension springs 20 are mounted on the lower edge of the rear rail Ill by 35 means of brackets 2i and securing tacks 22. At their forward ends the springs are hooked about the rod 19 and through the fabric l6. These springs serve to hold the fabric taut and tend to prevent it from assuming a bulging position 40 when the seat is unoccupied. It was pointed out as a primary object of this invention to provide improved yieldable support ing means for the spring supporting fabric sheet used in the seat construction of upholstered 45 furniture and that the chief means of providing this support was in providing supporting means . above the fabric. To carry out this object flexible cables 25 of wire, or flexible metal strap material or any suitable ?exible material are provided 50 which are secured at their ends by means of tacks 26 to the upper edges of the front and rear rails l3 and M respectively of the seat frame. Under neath the fabric l6 are supporting plates 21 which are pressed out to provide the eyes 28 at three 55 2 2,117,394 spaced points. These plates are positioned one beneath each of the cables 25 and in the same longitudinal plane. Connecting the cables 25 and the plates 27 are coil springs 29 which are hooked, one to each of the eyes 28, through the fabric and are attached to the cables 25. As shown in Fig. 3 the plates 21 are preferably formed with a convex upper surface in order that they will not present sharp edges to the 10 fabric. to the bottom of the frame on all four of its edges by tacks H. In this case supporting plates This eliminates the possibility of the plates cutting through the fabric at their side 39 are employed which extend entirely across the under side of the fabric sheet and are secured edges. to the lower edges of the frame by tacks 40, one at each end. Referring to Fig. 8 it can be seen that at each end these plates have formed there on upwardly extending pointed lips ill which may 15 be secured to the inner rails of the frame by means of tacks 92. These lips 4! are similar in all respects to the lips 35 of the plates 32 which are particularly illustrated in Fig. 6. Each of the With this construction the cables 25 are pref erably located between the rows of seat springs, 15 as is shown in Fig. 1 and thereby provide a yield able support for the fabric sheet. Although there is illustrated three coil springs connecting each cable 25 with each plate 21 it is not an essential feature of this invention that any particular 20 number of springs be used to connect the two elements. In the form of the invention shown in Figures 1 and 2 it has been found advisable to employ a shorter spring connecting the middle of each 25 plate 2? than the springs connecting the ends of each plate 2'! with the respective cables 25. However this construction is not essential to the invention and the springs may be made of any suitable length. 30 The construction whereby one end of the sup porting plates is secured to the bottom of the frame provides a stronger and somewhat stiffer action at the front of the seat. Referring to Figures '7 and 8, a further form of the invention is shown in which the fabric, here indicated as reference numeral 38, is tacked With the construction as shown, when the seat is occupied pressure on the upper portion of the seat supporting spring assembly l8 compresses the spring assembly l8 and depresses the fabric sheet it‘ to some extent. The downward move 35 ment of the fabric sheet is yieldably resisted by the ?exible cable 25 and tension coil springs 29 connecting it to the plate 21. When the seat is unoccupied the cable 25 and the springs 29 serve to restore the fabric sheet to its normal position as shown in Fig. 2, thus preventing permanent sagging or bulging of the ?exible sheet. In this connection the springs 20 cooperate with the sup porting structure above the sheet to keep the sheet taut and thereby aid in preventing sagging or bulging of the sheet. A modi?ed form of supporting means is shown in Figures 4, 5 and 6 in which parts similar to those in Fig. 1 bear corresponding reference nu merals. In this form of the invention a different type of supporting plate is provided beneath the fabric sheet, which is indicated by reference nu meral 32. This plate is attached at one end to the under edge of the front rail l3 by means of tack 33. The supporting plate is also provided with eyes 34 which are pressed from the plate and are similar to the eyes 28 of the plate 21. Near the end of the plate which is attached to the front rail of the seat frame, the plate is pro vided with an upwardly extending pointed lip 35 which is adapted to abut against the inner side of the front rail [3 and is secured thereto by means of tack 36. In the form of the invention shown in Figures 1i, 5 and 6 it has also been found useful to employ 65 the tension springs 28 to hold the fabric sheet taut. In this form of the invention, as an alter native construction, only two springs 29 are shown connecting each of the plates 32 to the respective cables 25 instead of the three con 70 necting spring construction as shown in Fig. 2. However the number of springs employed is op tional and it is not intended to limit this inven tion to any particular number of connecting springs between the various types of plate and 75 the cable 25. plates is formed with a convex upper surface ~ similar to plates 21 and 32. . In this construction there is also provided a ?exible cable 25 above each of the plates 39 and to which each of the plates are respectively con nected by means of the tension springs 29 which are hooked through the pressed eye portions 43 in each of the plates 39. The construction illustrated in Figures '7 and 8 is stronger and more rigid than either of the other forms of the invention and is particularly - useful where a strong rugged construction is de sired. In all forms of the invention shown it is to be noted that the cables 25 and springs 29 form yield able suspension members above the fabric sheet for supporting the fabric, the cables and springs being so arranged that they do not interfere with ihe upper spring supported structure or the seat. It is also to be noted that the placement of the tension springs connecting the cables and sup 40 porting plates at a substantial distance inwardly of the frame makes possible the assumption of the body load at points where it is applied. This is a decided advantage over other types of con struction. I claim as my invention: 1.
