2 'tllaims.

The present invention relates to cushions, particularly of the type used, for either seat or back cushions of automobiles or furniture.

It is the principal object of the present inven- 5 tion to provide an improved means for securing the edges of a sheet of upholstery material to the cushion.

Another object is to provide means for securing the edge of a sheet of upholstery material dim rectly to the metallic framework of a cushion of the type mentioned.

Another object of the invention is to eliminate the use of tacks and tacking strips commonly used to secure upholstery to seat and back cushions.

Other objects and advantages of the inven-' tion will become apparent from the following specification, the accompanying drawing, and the appended claims.

no In the drawing:

Figure 1 is a perspective view of a suitable framework of the type used in the back cushions of automobiles;

Fig. 2 is a perspective view showing the under side of the completely assembled back cushion; and

Fig. 3 is a section taken on the line 3--3 of Fig. 2.

in the drawing, the invention is shown as tit) applied to a cushion frame and spring assembly of the general type shown in the prior copending applications of Clarence H. Menge, Serial No. 44,697, filed October-l2, 1935, which matured into Patent No. 2,116,402, on May 3, 1938, and Serial No. 147,065, filed June 8, 1933. Briefly, this cushion framework comprises a marginal frame channel member it which extends entirely around the periphery of the cushion and suitable cross-members i2 which are integrally 4g secured, as by welding, at their ends to the marginal channel member iii. In the construction shown, the springs are of the sinuous type formed of a plurality of wire elements, each spring element it being composed of a plurality of simi- 4'555 lar adjacent later convolutions, all lying in substantially the same surface. The ends it of the spring elements, which extend transversely of the length thereof, are positioned within the channel member it, as shown best in Figure 3,

gm whereupon the inner margins of the channel members the above mentioned prior copending applications; to which reference may be had for further details of construction.

In accordance with the present invention, a substantially straight relatively heavy wire ii is 5 welded at its ends at it and it to the channel it at opposite sides of the cushion frame. In order to provide greater stiiiness, the intermediate portions oi the wire 51 are likewise welded to the transverse frame members i2 19 at it and 23. At the opposite or forward edge of the frame, a similar wire 22 is 'Welded at 23 and 26 to the side channel members It and at 25 and 25 to the transverse frame members i 2. At the sides of the frame are secured a pair of 35 similar wires 21 and 28, welded respectivelyto the rear wire it at 29 and 39 and to the front wire 22 at it and In order to reinforce the wires 27 and it, they are provided intermediate their ends with offset portions 33 and respectively, which are welded to the side frame channel members iii. The wires ill, 22, 2?, and 28 are preferably secured at the under side of the cushion frame and are spaced inwardly from the marginal channel members iii, as best shown in Figures 1 and 8.

The cushion is provided with a suitable layer of padding 3%, which is carried by a backing 'layer 37 and a layer of finish upholstery fabric upholstery is stretched over the frame, the marginal portions of the backing and" upholstery layers?! and 38 may be wrapped around wires ii, 22, ii and 28, and secured thereto by means of clips it), which are of the hog ring type. These clips pierce the double thickness of both layers 4o 3'? and 38 in the area at which they overlap each other, and the clips entirely surround the wires ll, 22, 27, and 28, thus securing the marginal edges of these layers firmly to the frame.

It will be noted that the clips or hog rings are so formed upon assembly that their ends 4| and t2 cross each other at an angle. Accordingly, the projecting end 42, for example, prevents withdrawal of the opposite end M from the material, and vice versa. There is thus provided an exceedingly simple and efiective means for securing the margins of the upholstery material to the frame. This arrangement is exceedingly effective in view of the fact that a large portion of any tension forces exerted upon the uphol- 5 ion frame is equally applicable to any other of the known types of cushion. frames. It is apparent that variations in the arrangement disclosed may be indulged in without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is:

i. In a cushion construction, a frame having an elongated element extending inwardly from 'an edge thereof, a layer of upholstery material stretched over said frame with a marginal portion thereof wrapped about said element, and wire rings surrounding said element and passing through a double thickness of said layer to form the sole means for holding the material in wrapped relation with respect to said element.

2. In a cushion construction, a frame having a portion defining a marginal edge for the cushion. a wire secured to said frame and extending along said marginal edge inwardly thereof, and

a sheet of upholstery material stretched over said frame and having an edge extending over said marginal portion of the frame and wrapped around said wire, and U-shaped clips of wire disposed over said wire in position to pierce a double thickness of said material when clamped thereon to form the sole means for securing said material to said frame.
