CHAIR BACK CONSTRUCTION Filed May 12, 1928 Patented Apr. 7, 1931 UNITED STATES PATENT OFFICE MATTI-IYS NUBERG, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO AI/IERICAN SEATING COMPANY, OF GRAND RAPIDS, MICHIGAN, A CORPORATION OF NEW JERSEY CHAIR BACK CONSTRUCTION Application filed May 12, 1928. Serial No. 277,363.

This invention relates to a chair or seat back construction.

The main objects of this invention are to provide an improved chair back which will be of substantial and rigid construction; and to provide a back which is adapted to slidably receive an upholstered back and from which the upholstered back may be readily removed for repair or replacement.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Fig. 1 is a view in perspective of the rear side of a theatre seat provided with my improved back construction.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is an enlarged sectional detail view of the left end of Fig. 2.

In the construction shown in the drawings, the improved back comprises a rearwardly bowed sheet metal panel 1 of inverted U shape, bounded up the sides 2 and 3 and across the curved top 4 by an inwardly facing channel shaped frame 5. The adjacent marginal edge of the panel 1 is attached to the inner side of the rear flange 10 of the frame 5, preferably by welding or brazing.

The lower ends 6 and 7 of the channel frame are left open and the frame is omitted across the lower end 8 of the panel 1, so that an upholstered back 9 of substantially the same size and shape as the panel 1, may be slid edgewisc up into the inwardly facing channel frame 5, and detachably secured therein by screws 12 which pass through holes in the panel 1 and engage the upholstered back 9.

The back 9 is retained in the frame 5 by the front flange 11 of the frame overlapping the marginal edge thereof along the sides and across the top.

The upholstered back 9 is preferably constructed by placing a suitable amount of padding 13 on a plywood base member 14 and then covering the same with suitable plush cloth 15 which is wrapped around the marginal edges of the wooden base 141 and secured to the back thereof by tacks 16.

Means are provided for securing the back to seat ends 17 and 18 of a theatre seat, and comprises sheet metal lugs 19, welded or otherwise suitably secured, to the channel frame 5 at opposite sides thereof, as shown in Fig. 1. The lugs 19 have suitable notches for embracing the shanks of attachment bolts 20 which are secured to the seat ends 17 and 18.

In the use of this seat back, upholstered members 9 of various colors and grades may be readily slid into the channel frame 5 and secured therein by the screws 12. The notched lugs 19 permit the seat ends 17 and 18 to be positioned and secured to the floor and then have the lugs attached. Likewise when it is desired to remove a back for repair or replacement, the bolts 20 are loosened and the back as a unit removed from the seat ends. The screws 12 are then removed and the upholstered back member 9 slid out of its channel frame. 7

Due to this improved construction, the up holstered backs of theatre seats may be replaced or repaired at a minimum of expense and labor.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims:

I claim:

1. A chair back comprising: an inwardly facing channel member having a middle upper portion and downwardly extending side portions; a panel member in the channel of the channel member, united at its rear side adjacent its edge with the inner side of the rear flange of the channel member; a back member slidably inserted upwardly into the channel of the channel member between the front flange thereof and the panel member; removable means extending through the panel member and into the back member for releasably holding the back member in the channel of the channel member.

2. A chair back comprising: an inwardly facing channel member having a middle upper portion and downwardly extending side portions; a panel member in the channel 0 the channel member and united at its rear side adjacent its edge with the inner side of the rear flange of the channel member; a, back member slidably inserted upwardly into the channelback member comprising arearward base part and a forward upholsterysheet turned rearwardly over the edge of the base part and having its edge portion fastened to the rear side of said base part and serving to space 'said base part and the panel member apart;

and a screw extending through the panel member, offset from said edge portion of the upholstery sheet, and into said base part for releasably holding the back member in the channel of the channel member.
