Original application November 30, 1940, Serial N 0. 367,903. Divided and this application October 25, 1941, Serial No. 416,477

6 Claims.

The present invention relates to chairs and more particularly to chairs of the theater type such as are installed in rows in motion picture houses, opera houses, auditoriums and the like.

The primary objects of the invention are to provide a theater chair having improved means for attaching upholstering material to the chair back and for mounting the chair back on its supchair, the seat thereof being shown in a raised position of non-use;

Figure 2 is a view thereof shown partially in section taken on line 22 of Figure 1; v

Figure 3 is an enlarged fragmentary sectional View thereof taken on lines 3-3 of Figures 1 and 2;

Figure 4 is an enlarged central vertical sectional view through the top portion of the chair back;

Figure 5 is a sectional View similar to Figure 4 but showing a modified construction of the chair back;

Figure 6 is a, fragmentary front elevational view of the modified form of a chair back shown in Figure 5;

Figure 7 is a fragmentary perspective view of securing means for attaching the marginal edge of chair back upholstery material to a peripheral rod; and

Figure 8 is a. fragmentary plan view of the securing means shown in Figure 7 prior to its application to the upholstery material.

Referring now in detail to this drawing wherein like parts are designated by the same numerals in the several views, the theater type chair there shown comprises a chair seat generally designated l and a chair back generally designated l l independently mounted between and supported by a pair of horizontally spaced vertically disposed chair supporting standards l2 having arm rests l 3 secured thereto. Such chairs are conventionally installed in rows, each standard l2 serving as a support for the two chairs on opposite sides thereof.

The chair back as shown in Figures 1, 2, 3, and

4 comprises a horizontally rearwardly bowedand vertically forwardly bowed metal back plate l4 having a continuous rearwardlyextending flange l at the? top and sidesthereof. IPadding l6 of cushioning material such as cotton, hair or sponge rubber is disposed over the front surface of the back plate l4 andan upholstery sheet ll of suitable material such as fabric or leather covers the padding l6. An elongated semi-rigid member such as the rod orwire i3 is secured as by stitching l9 withinthe continuous hem at the top and side margins of the upholstery sheet I1, and the continuous rearwardly extendin flange IS on the back plate It is curled out.- wardly, forwardlyand then inwardly to form a pocket 2| embracing and firmly retaining therein the rod 18 and the hem 20 at the top and side margins of the upholstery sheet ll '(seeFig- "ure 4) The relatively wide side portions 22 of the rearwardly extending flange l5 on the back plate M are secured to the supporting standards l2 as by means of bolts 23 extending through the side portions 22 of flanges IS on adjacent chair back plates l4 and through the supporting standard l2 therebetween and provided. with nuts 24.. The chair back II as thus constructed possesses sufficient flexibility to adapt itself to the angularly positioned standards in a curved row of chairs.

Figures 5 and 6 illustrate a modification of the means for securing the upholstery sheet to the back plate. In these views, the back plate 25 is provided at the top and sides thereof with a continuous rearwardly extending flange 26 which is curled outwardly, forwardly and then inwardly prior to the assembly of the chair back to form a pocket 21 having a forward opening 28 of sufficient width to permit insertion therein of a rod 29 and the hem 30 of an upholstery sheet 3| covering the padding 32. In this instance. a plurality of spaced clips 33 are provided, each having a portion 34 secured to the back plate 25 and a springable portion 35 extending into the pocket 21. These springable portions 35 of the clips 33 normally press forwardly and upwardly toward the inwardly curled portion of the flange 26. It will be seen thatthe springable portions 35 of the clips 33 will yield to the position indicated in dotted lines in Figure 5 when the rod 29 and hem 3B of the upholstery sheet 3| are inserted into the pocket 21, but after such insertion, these springable portions '35 of clips 33 spring forwardly and upwardly to securely retain the rod 29 and the hem 3B of the upholstery sheet 3| within the pocket 21.

Figures '7 and 8 disclose modified means for securing a flexible sheet like the upholstery sheet of the chair back previously described, to the rod within the marginal edge of the sheet to eliminate stitching of the sheet. A thin sheet metal strip 36 is formed with wide portions 37 and narrow connecting portions 38 as shown in Figure 8. The marginal edge of the flexible upholstery sheet 39 is folded over the rod 40, and the wide portions 31 of the metal strip 36 are then independently curled around both the flexible sheet and the rod thus gripping the sheet between the metal strip 36 and the rod 40.

While but several specific embodiments of the invention have been herein shown and described, it will be understood that certain details thereof may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims:

I claim:

1. In a chair structure of the class described, a pair of horizontally spaced vertically disposed chair supporting standards, a chair back supported by said standards and comprising a back plate provided with a continuous flange at the top and sides thereof extending rearwardly and then curled outwardly, forwardly and inwardly to form a pocket, a plurality of clips each having a portion secured to the back plate and a springable portion extending into said pocket and normally pressing forwardly-upwardly toward the inwardly curled portion of said flange, padding over the back plate, an upholstery sheet covering the padding, a rod secured within a continuous hem at the top and side margins of the upholstery sheet, said rod and the hem of the upholstery sheet being inserted within the pocket in the back plate, the springable portions of said clips yielding to permit the insertion of the rod and the hem of the upholstery sheet into the pocket and springing forwardly-upwardly to retain the rod and the hem of the upholstery sheet within the pocket after such insertion.

2. In combination, a sheet of covering material having an enlarged bead at its periphery, a body having a peripheral channel to receive said bead,

said channel being larger in cross section than said head and having a restricted entrance throat at least as wide as the diameter of said bead and a plurality of clips attached to said body and having flexible portions located within said channel and engageable with the inner edge of said bead when said bead is inserted into said channel.

3. A sheet of covering material having an enlarged bead at its periphery, a body having a peripheral channel formed therein to receive said bead, said channel having a continuous entrance throat, a portion of said body being turned inwardly to restrict the width of said entrance throat, a plurality of clips attached to said body at said entrance throat opposite said inturned portion and having flexible portions extending into said body and engageable with the inner edge of said head when the bead is inserted into said channel.

4. The combination of elements defined in claim 3, combined with resilient padding material inserted between said body and said covering material, said beading being yieldable to permit insertion of said bead into said channel and resilient to retain said bead in contact with said clips.

5. In combination, a plate provided with acontinuous flange at its periphery extending rearwardly and then curled outwardly, forwardly and inwardly to form a channel having a continuous restricted throat, a plurality of clips each having a portion secured to the plate and a flexible portion extending inwardly into said channel and normally pressing toward the inwardly curled portion of the flange, an upholstery sheet covering the plate, an enlarged bead formed at the periphery of said sheet, said bead being inserted into said channel, the flexible portions of said clips engaging the inner edge of said bead.

6. The elements in combination of claim 5 in which said head comprises a rod confined within a hem at the periphery of said upholstery sheet.

STANLEY J. GEDRIS.
