3 Claims.
This invention refers to seat upholstery in gen
eral but in particular to an upholstery unit and
the method of making the vsame especially
adapted for use on the light weight or airplane
‘5f type of seat.
'I'he seat frame with which the upholstery unit
is intended to be used is of the so-called aeroplane
type having a frame with a top part or curved
bar over which, a pocket at the top of the unit is
il) adapted to be hung and having a cross bar at the
front edge of the seat to which is attached the
lower part of the unit. Thus the upholstery unit
is detachably supported at its extremities by the
" frame and acts as a free suspension unit in sup
1-.3 porting the seat occupant substantially as is
shown in Patent 1,815,836. The upholstery units
as previously made for this type of seat have al
ways had a large amount of stitching visible
which not only detracted greatly from the ap
2 O pearance of the seat, but was liable to rip or un
ravel. It is an object, therefore, of this inven
tion to provide an upholstery unit wherein all
stitching is invisible. l
A further object of the invention is the pro
;¿5 vision of a new and improved upholstery unit
having a supporting pocket at the upper por
tion.

Referring now to the drawings in detail and
iirst to Figure l, it will be seen that the unit is ¿o
formed of a strip 2 of canvas or other strong
material out to the proper shape and upon which
is laid a suitably cut strip li of velour or other
desired material with the finished side or nap

40 which:
Figure 1 is a view showing the unit in the iirst
stage of construction;
Fig. 2 is a view similar to Fig. 1 but showing the
second stage of the construction;
Fig. 3 is a sectional View taken on line 3_3 of

with the stitching completed;
Fig. 6 is a view showing the upper portion of
the unit in the fifth stage of construction, the
55 lower portion having been turned inside out:
of the velour for a purpose to be later described. 40
Next a strip of pantasote 24 is laid face down
ward upon the unit as shown in Figure 1 and
stitched as at 5.96 to form the unit as shown in
Fig. 2. It will be noted that the stitching goes
only to the bend 2l leaving the upper portion Z8 «i5
free to be folded back allowing the Ybilo to be fold
ed over upon the velour as shown in Fig. 4.
The
reenforcing webbing strips` I3 are folded inward
and the upper portion 28 of the pantasote folded
over upon the bib and the entire upper portion 50
stitched as at 3u (Fig. 5) thus forming a pocket
at the upper portion of the unit having its mouth
covered by the portion 28. The unit is now in
condition to be partly turned and the lower por
tion is brought up through the unstitched open~ 55

ing.32 which will bring the unit to the position
shown in Fig. 6 with the pocket still unturned
but with the mouth thereof uncovered. It is
thus seen that the lower portion of the unit is
turned about a point which is above the pocket
opening or mouth and that the portion 28 of the
pantasote is thus turned over and protects the
stitching, while the reenforcing strips I3 have one
end free which end is now bent around the edge
of the unit and secured'to the upper portion 28 of
the pantasote strip 24 by stitches 34 extending
through the canvas 2 and the velour.
The pocket is now turned inside out by pushing
concealed as well as a portion of the stitching
within the pocket at its lower or open edge.
In the second form a tube is partially formed
and turned inside out after which a pocket is
formed which when turned inside out will cap the
tube thus presenting a finished product having
all boundary stitching concealed but with the
stitching within the pocket unprotected other
than by the reenforcing tabs I3.
The material “Pantasote” throughout the pre
ceding description is a form of artificial leather
manufactured by the Pantasote Company, Incor
porated of New York city and is used purely as
the top of the pocket through the pocket opening Vrepresentative of the various manufactured or 15
natural materials such as leather that may be

What is claimed is:

may be secured, the pillow thus completely con
cealing all previously visible front stitching. The ing an enlarged end portion and a finished sur

places the unit in the condition shown in Fig. 13 having protected seams which consists in pro

jection and a marginal edge portion of the same
now be turned inside out by rotation about the
pocket opening thus bringing the unit to its final general contour as the upper end of said strip,
arranging said bib adjacent to and in longitu
or finished condition which from all outward ap
dinal alinement with said strip with the projec
pearances is identical with that of the unit pre
viously described, but the inside of the pocket tion overlying the latter, placing a binding tape
upon and along the longitudinalV edges of said
differs in that the lower portion of the seam with

in Figs. 1 to 12 inclusive the lower portion of the strip and said projection, placing a shorter strip
seam within the pocket is protected by the turned of material with its finished face turned down

In the ñrst form it is seen that a tube is formed
having a pocket at the upper portion with the
pocket mouth inside of the tube and that the
tube is turned inside out rotating about the top
edge which is substantially above the pocket
70 mouth thus protecting at least a portion of the
seam above the pocket mouth as is clearly shown
by Figs. 6, 9 and 11. After the tube has been
turned then the pocket is turned inside out to
complete the unit wherein the tube is capped by
75 a pocket and all exterior or boundary stitching is

ñrst strip to a point approximating the enlarged
upper end, thereby forming a tubular body with
upper and lower flaps, reversing said tubular body
through its upper end, folding the bib over the
upper end of the first strip and overlapping the
upper flap of the second strip, sewing said bib
along its upper and side edges to both strips, and
reversing said bib structure.
3. The method of forming an upholstery unit 75

having protected seams which consists of pro
viding a strip of material with the face upward,
placing a bib with the face upward adjacent the
strip and having a projection overlapping said
strip, placing a beaded binding upon said strip
adjacent the edges thereof and with the bead
inward, securing said binding, strip- and bib pro
jection together, placing a second strip of mate

of said second strip to- said binding and ñ'fst

ing and between‘the binding and the unsecured
portion of said second strip, securing said bib and
the unsecured portion of said second strip to said
binding and ñrst named strip to form a pocket
and open ended tube, turning said tube and
pocket inside out whereby the bead and the faces
of the strips and bib are placed on the outside
of the unit.
