Application filed March 24, 1927. Serial 1lo. 178,064.
This invention relates tospine supports and has for an object to provide an improved construction wherein a desirable support is provided, capable of arrangement in chairs, sofas or other places,A whereby a proper support to the back or spine of a person may be had.
Another object otthe inventionv is to provide a support toi' the back or spine, wherein supporting means are presented which may be adjusted to fit dierent sized persons and different shaped spines.
A still further object of the invention is to provide a spine support which may be loosely placed in a chair ot conventional shape and design or may be suspended from the upper part of the chair so as to engage `and properly support the spine, principally f at what is commonly knownas the small of the back.
. In the accompanying drawing- Figure 1 is a side View of a chair, with a support embodying the invention applied thereto, the chair and support being shown in connection with a ligure in dots, illustrating the contact with the spine.
/ Figure 2 is an enlarged front view of the support shown in Figurel, certain parts being broken away for better illustrating the construction.
Figure`3 is a sectional view through Figure 2 Online 33. Figure4 is a view similar to Figure 3 but sliowlng the filling eliminated and showing how the flexible members may be adjusted.

or other article.
Referring to .the accompanying drawing by numerals, 1'indicates an ordinary chair.
of the stiff back. variety,fand 2 a support resting on the seat 3. Where the person is too large or small, or for some other reason, the support 2 -is not properly located for engaging the curvature in the back immediately abovevthe hips, the support may be 'raised and supported from the upper part of the In Figure 5, hooks 5 o ver the back 4, said hooks being-connected with the support 2 by suitable flexible members or cords 'i' and 8. The cords are preferably slipped throughl suitable eyes 9 in the respective hooks and secured by a suitable knot 10. By untying the knot 10, the
effective length of the cord may be adjusted so that the support 2 will be held at the desired' height. In the drawing, the chair 1 is shown bilt it is evident that .a dierent kind of a chair, seta or other article could receive the support 2 and could be supported thereby loosely by hooks 5 and 6 or if desired, could be embedded and form part of the sofa or other support. This is particularly true where upholstered chairs or solas are to be supplied with a support 2. Regardless of the place where the support 2 is to be used, the construction is as shown in Figures 2,3 and 4.
From these figures, it will be observed that the support 2 is provided with al back 11, which is preferably stili?, lor which is preferably formed ot' some light wood. A plulrality etwooden braces 12 are also provided and secured byscrews or otherwise to the back 11. Preferably, each of these braces is provided with a short flat section 13 against 'which the bottom plate 14 rests, said bottom plate being secured by screws or otherwise to the braces 12 and to the back 11. There have been shown four braces 12 in the drawing, but it will be evident that a greater number .mightbe used or even a less number. As
shown in Figure 2, there is a brace 12 at each end of the back 11 and two spaced evenly between the ends. Each of the braces 12 is provided'witll an inclined upper spring receivingsection 15 and an inclined spring re- 'ceiving section 16 at the lower end. Thesection 16 is the outer surface of a projecting portion 17. Associated with each of the braces 12 is a spring 18, which is a lat spring,and which at the upper end, is preferably secured in place by one or more screws 19. At the lower end, the spring 18 is provided with a number of apertures 20 and said apertures being adapted to receive a screw 21. The provision of these apertures permits a longitudinal adjustment of the i or usual place in the extension 17. Thisl will bowed to a greater extent so hold the s rin p date a greater'curvature of the as to accomm back. The aim is to have the bow ot spring 100 spring 18 and', consequently, causes the same l to bow to a greater or less extent, according 1 i springs j the front, over terial, may
18 such as to substantially fit the-small of the back whereby an eicient bracing and supporting' action is secured. Preferably, a transverse flat spring 22 is riveted or otherwise rigidly secured to all of the springs 18 as shown in Figure 2. This holds the springs against accidental-shifting and assists 1n holding the packing' 23 in place, Suitable metallic or textile straps or cords 24 are alsol secured to the springs for holding the packing 23 in place. This packing may be cotton, hair or other suitable packing as desired. Under some circumstances, the packing is completely eliminated and the are used to present the only support. It is, of course, evident that the spine suport may be made in different sizes to fit diferent sized persons, while the adjustment of the sprin to fit di erent eurvatures of spines. After parts have Abeen once adjusted, they are usua After the parts have been assembled and the springs 18 adjusted as desired, a covering 25 of leather or other material is stretched over the springs 18 which ma be termed the the sides and a seover the back. This covering of leather, fabric or other mabe held in place by tacks or other securing means. Wherc the device is'used on upholstered chairs or sofas,rv preferably the covering 25 is of material matchingin color and general appearance withthe upholstery.
What I claim is:
1. A spine support, comprising a back, a plurality `of bracing members connected w1th the back, each of said bracing members havelled upper bers, said 18 readily permits an adjustment ly left ,in this position continually.-
ing a beveled upper end and a projecting lower end, said projecting lower end having an inclined section, a flat spring for each of said bracing members, said' fiat springs at their ends fitting flatwise against the beveled sections at the top and bottom, means for adjusting each of said springs independently for varying the degree of permanent bowing of' the spring, and covering'means for covering said springs, back and bracing members.
2. A spine support, comprisin a stiff back, a plurality of bracilg mein ers connected withI said back on one face thereof, each of' said bracingmembers having a bevend and a projecting lower end, for each of said bracing memat springs at their ends fitting fiatwise against the bevelled sections lat the top and the projecting lower ends at the bottom, and means springs independently for'varying the dea flat sprin gree of permanent bowing thereof.
8. A spine support, comprising-a back, a
plurality of bracing members secured to the back and extending from the top to the bottom thereof, each of said bracing members 'having a projecting lower end, one ofsaid projecting -lower' ends having an inclined section, a
