C. E. M CORMICK UPHOLSTERED SEAT 2 Sheets-Sheet 2 Filed Sept. 17, 1928 Patented Apr. 15, 1930 UNITED STATES CHARLES E. MCCORMICK, F DETROIT, MICHIGAN UPHOLS'IERED SEAT Application filed September 17, 1928. Serial No. 306,379.

This invention relates to seat cushions and seat backs and has for its object the production of a cushion pad which may be manufactured at a low cost and which will retain its shape, although subjected to hard usage. The invention is intended primarily for embodiment in automobile seats but may be applied to any upholstered seat. The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features being particularly pointed out in the appended claim.

In the accompanying drawings;

Figure 1 is a perspective view of a seat comprising seat cushion and seat back, the upholstery cover being broken away to show the pad construction,

Figure 2 is a transverse section on the line 22 of Figure 1,

Figure 3 is a plan view of a part of the cushion pad, the relative location of the retainer wires being indicated by dotted lines,

Figure 4 is a plan view of the pad cover as it appears before being applied, the retainer wires being shown detached,

Figure 5 is a plan view showing a portion of the pad cover before the edges are hemmed,

Figure 6 is a plan view of the pad showing the lining below,

Figure 7 is an edge View of the pad, showing the edge of the lining which holds the pad material together.

The spring assemblies may be of any preferred type including coiled sprlngs 1 tied together, the outside coils being held in proper position by a border wire 2 which determines the shape of the finished cushion.

The pad may be of the usual constructlon consisting of a layer of cotton, hair or other cushion material 3 attached to a woven lining 4; the entire pad being cut to a shape similar to but somewhat larger than the area defined by the border wire 2, so that when the pad is laid on the spring assembly with the woven lining 4 next thereto, its edges may be rolled around the border wire 2, thereby completely enclosing same as shown at 5. The rolled edges of the pad are held securely in the position shown most clearly in Fig. 2 by a pad cover 6 of light woven material which covers the entire unprotected surface of the pad, the edges of the cover passing around and under the rolled edges of the pad.

When the cover 6 is cut from the stock of material, a tongue 7 is formed along each edge, each tongue terminating short of the meeting edges, as shown in Fig. 5. The tongues 7 are folded back and sewed onto the body of the cover to form open ended hems or tubes 8 through which retaining wires 9 are inserted. The retaining wires have hooks 10 or are otherwise formed at their ends in order that they be interengaged and held together. It will be noted upon reference to Fig. 8 that the retaining wires are shorter 6 than the edges of the pad at which they are respectively applied. After the pad is in place, the meeting ends of the several wires are interengaged, as indicated at 11, and the edges of the cover are thus drawn toward each other so that the sides and ends of the pad are rolled around the border wire 2 and will completely house the same.

After the pad has beenthus placed in position on the sprin structure, any usual outside upholstery cover 12 may be put over the assembly and fastened in the usual manner.

The retaining wires are easily inserted and connected and draw the edges of the pad around and under the border wires so that 80 said border wires are completely housed and the pad is effectually held in place.

The pad material is protected on both faces so that it will not be torn apart, and the folds or rolled edge portions of the pad are not subjected to pulling or chafing strains across the border wires as is the case with the usual methods of assembling pad to spring. This feature protects the rolled edges of the pad so that they will not quickly become distorted or deformed but will retain their shape for a long period even when subjected to hard usage. The pad, pad cover and retainer wires embodying my invention may be produced and applied to the foundation spring struc- 95 ture easily, rapidly and at a low cost.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

In combination with a seat spring structure loo having a border wire around its top portion, a pad extending over the spring structure, a woven cover for said pad having a hem on each edge shorter than the edge, and retaining wires inserted through the respective hems and shorter than the respective edges of the cover, said wires having hooks at their ends whereby when the hooks on the ends of meeting wires are interengaged the edge portions of the pad and cover will be drawn over the border wire and held under and at the inner side thereof to be shaped thereby.

In testimony whereof, I have signed this specification.

CHARLES E. MOGORMIGK.
