Undergarments and ~lethod of ~Iaking ~ame
This invention rela.tes to panties, briefs and
like undergarmen~s and to a method o~ making such
u.ndergarments.
~hroughout the specification and the appended
claims, the terms '1upper" or "upward" and "lower" or
"downward" as used for un.dergarments and component
pieces thereo~ are based on the position of the under-
~ garmerlt worn on the human body.
10 V11th conventional undergarments, such as
~: panties and briefs, the piece of fabric for covering
~: :
:~ the lower abdomen and the~piece o~ fabric for covering
~ the buttocks are:formed in conformity vrith the shapes
;~ ~
~: obtained by projecting the lower abdomen and the
~- 15 buttocks from the ~ront or rear, wlth no con~ideration
~ giVen to the bulges of the lower abdomen, lateral
:~ region~ and buttocks o~ the hwnan body. Accordingly
vrhen ~uch an undergarment i~ worn, the large prominences
o~ the buttocks tension the buttock covering piece,
:,
pulling the:lower abd~men covering piece toward the
:
bu:ttocks through~the~crotch and consequently drawing
: the abdomen covering piece downward in its entiret~,
~; with the midportion of its width pulled most strongly.
As a~ result, the u~er hem o~ the abdomen covering
:
~: . :.,

1~52~
piece is curved downward most markedly at the midportion.
With the front portion of the undergarment pulled down,
the rear portion of the undergarment, i.e. the buttock
covering piece, is raised relative thereto. Thus the
upper hem of the undergarment inclines downward from the
rear toward the front. The undergarment then appears
unattractive in design and feels uncomfortable to wear.
Undergarments heretofore known have another
problem that when they are worn, the portion of the
undergarment covering the buttocks extends merely in a
planar fashion over the gluteal cleft between the
buttocks and hangs loosely at its lower part to form
wrlnkles, thus failing to give a graceful appearance.
Conventional undergarments are further uncomfortable
to wear since the garment is unable to fit over the
buttocks and the gluteal cleft in intimate contact
therewith for enclosing and supporting these body
portions.
The present in~ention ha~ overcome the above
drawbacks and provides panties, briefs and like under-
garments which appear graceful in design and are
comfortable to wear, and a method of making such under-
garments.
The undergarments~ of th~s invention comprise
a front part for covering the lower abdomen, a rear
- 2 -

part chiefly for covering the buttocks, and a c~nnector
part interconnecting the front part and the rear part
for covering the crotch, the front part having a
projection extending outward from each of its upper
opposite side portions, the rear part having a projec-
tion extending outward and obliquely upward from each
of its upper opposite side portions, the rear part
having an upper edge curved downwards, most greatly on
: the center line of the rear part, the projections of
the front part joining the projections of the rear
part at their opposed ends.
Since the projections of the rear part
extend outward and obliquely upward from the upper
opposite side portions thereof with the upper edge of
the rear part curved and recessed most greatly on the
center line o~ the rear part, the rear part can be
bulged in conformity with the prominences of the
rearwardly bulging buttocks and the sidewise projecting
lateral regions of the human body. The undergarment
is there:Eore comfortable to wear. When the garment is
worn, the upper hem thereof ~s positioned straight
horizontall~, so that the undergarment appears graceful 1
in design.
The present in~ention is useful for provid;~ng
undergarments of any of the following types: the deep-
- 3 -
.., ~

". ' ~'

5 ~ ~J ~
type undergarment which is adapted to fully cover the
forwardly bulging portion of the lower abdomen with
its front part; the medium depth-type undergarment
which has an upper hem positionable on the top of the
bulge of the lower abdomen; and the shallow-type under-
garment which has an upper hem positionable some
distance below the top of the bulge. The character-
istic shapes of the front and rear parts included
in these types of undergarments will become apparent
from the following description of embodiments.
Further according to the present invention, the seams
of the projections of the front and rear parts are
so positioned as to give an attractive appearance to
the undergarment.
The present invention also provides a method
of making undergarments comprisincJ a front part for
coveriny the lower abdomen, a rear part chiefly ~or coverincJ
the buttocks and a connector part for covering the crotch
by stitching these parts together at suitable portions, the
2Q method comprising forming on the front part a
projection extending outward from each of its upper
opposite side portions, forming on the rear part a
pro~ection extending out~ard and obliquèly upward from
each of its upper opposite s~de portions, formin~ on
the rear part and upper edge cur~ed downwaras, most greatly

on the center line of the rear part, stitching
the rear part and the connector part together at
adjoining portions thereof while stretching the rear
part toward the connector part most greatly along
the center line of the rear part and to a progres-
sively lesser ex-tent from the center line toward
the opposite sides thereo~ to form an elongated
depression on the center line of the rear part and
a bulged portion on each side of the depression
when the undergarments:are worn.
Accordingly when the undergarment made is
worn, the upper hem of the garment is positioned
straight horizontally. Since the undergarment is
formed with bulges which conform to the bulges of
the buttocks and of the lateral regions o e the human
body and also w~th a depression which is positionable
along the gluteal cleft, the undergarment is
intimately fitta~le to curves Oe the human body,
appears graceful and feels smooth and comfortable.
In addition the undergarment can be made with extreme
ease without necessitating any special procedure or
material for cutting the fabric mater~al or for th.e
sewing step~
The undergarments of the present invention
~, - 5 -

are made preferably from stretchable knitted fabrics.
According to the me~hod of this invention, the ~ront
part, the rear part and the connector part may be
cut out from a fabric individually separately.
Alternatively the front part and the rear part, the
front part and the connector part, or the rear part
zLnd the connector part may be cut out as an integral
piece.
The present invention is useful not only for
panties and briefs but also for corsets, girdles, etc.
for covering the lower trunk of the human body. The
invention is similarly useful for the lower trunk
portions of leotards, bathing suits, sportswear,
foundation garments such as all-in-ones, etc. which
are adapted to cover both the upper and lower trunks
of the body.
With reference to the drawings, the preferred
embodiments of the present invention will be described
below.

~ igs. 1 to 3 show curves delining the lower
abdomen, waist and buttocks of the h~-~an boay, and
three kinds of undergarments. As is ~ell knovrn, the
h~an body is constricted at the waist A. On the back
side of the body below the waist A the-re are buttocks ~
bul~in~ rearward from the waist A down~Jard and separated
from each other by the ~luteal cleft. On each side of
the human body, the lateral re~ion C corresponding to
the lateral part of the pelvis above the thi~h is bul~ed
outward. On the front side of the body, the lower
abdomen D ia sli~htly bulged forward.
~ ig:. 2 shovl~ the following Phantom lines: A
center line N dividing the waist A into fron~ and rear
equal portions; a vertical line M dividin~ the waist A
into front and rear portions in the ratio of about 1:2;
~;~ a horizontal line ~l extending through the wai~t A; a
horizon-tal line ~2 extending through the most pro~ecting
portion of the lower abdomen D; a horizontal line 13
at a level sli~htly belo~ the horizontal line ~2; a
~hor1zontal line 14 at a level slightly above the
most projecting portion of the buttock ~; and a horizon~
tal line ~5 a~proximately at the level of the crotch.
.
. 3 shows crDss sections Sl to S5 of the human body
taken alon~ the horizontal lines ~l to ~5, respectively.
With reference to ~l~. 2, the intersections
-: : '.

5~5
of the center line N with the horizon-tal lines ~l and
14 are indicated at 0 and P, and the intersections of
the curve defining the back of the human bo~y with the
horizon-tal lines Ll and L4 are desi~nated at Q and R.
The line through the ~oints 0, P7 the line through the
points Q9 R and the horizontal lines Ll, ~4 form a
trapezoid wlth legs of u.nequal lengths, the leg OP being
vertical. The trapezoid, when rotated about the center
line N, generates a truncated cone. When the trv.ncated
cone is divided by the plane containing the vertical
line ~l and perpendicular to the drawing, two segments
are obtained. ~lg. 4 shows the segment ~ of the larger
volume.
The truncated cone segment T will be considered
to be a model of the portion o~ the human body f'rom the
waist to the buttocks, namel~ between the horizontal
lines Ll and ~4, rearward from the vertical line M. To
be ~ure, the truncated cone segment T serving as the
model slightly dif'fers from the corresponding portion
20 of the human body, because the cross sections o~ the boay :!
along the horizontal lines ~1 to ~3 resemble an ellipse,
hereas the segment T~is circular in horizontal cross
section and further becau.se the portion of the body from
the waist to the buttocks has a complicatedly curved
surface, wh~reas the segment T has a simply curved

eripheral surface. However, the se~men-t T i~ a very
useful model i~ considering the bvlges of the buttocks B
and lateral xegions ~ of' the body.
Fig. 5 is a development shov~ing the peripheral
surface of the truncated cone segment T other than its
cut surface S. With reference to this development, the
segment has an u per edge E and a lower edge ~ both of
which are in the form of a circular arc and are curved
upward toward their opposite ends. The sides G at the
opposite ends are inclined upward toward the center line
of the develop~ent. A piece of fabric cut out in
conformity with the development will adequately and
fully cover the peripheral surface of ~Le segment rl7 except
itscut surface S. It is assumed that the segment T has
a phantom line K on its peripheral surface as seen in
Fi~. 4. The line K extends on the peripheral ~urface
approxiMately in parallel to the line QR from a corner of'
the cut surface S at the upper edge of the segment T.
When portions J each def'irled by the line K and the
vertical edge of the cut surface S are re~!oved from the
cut-o~t piece covering the peripheral surface of the
segment T, the resulting plece has a shape defined by
the circular arcs E, P and lines H. ~he sides H at the
opposite ends ofthe cut piece are also inclined upward
toward the center llne of the cut piece.

~ his invention provi~es -three kinds of under-
garments, the first of ~hich is of the deep type. i/hen
worn, the garment of this type has its upper hem posi-
tioned at -the horizontal line ~1 and completel~ covers
the bu-ttocks ~ and also the bulging lo~er abdomen D~
When the second u~dergarment, which is the medlum depth
type, is worn, the upper hem thereof is positioned at
the horizontal line L2. ~he third is of the shallow type,
which when worn, has its upper hem positioned at the
horizontal line ~3. As will be described later 9 the
u~dergarments of the meaium and shallow types also fu.lly
cover the but~ocks. Any~of these three types of under-
garments is designed to have a straight horizontal upper
hem when worn.
As wlll become apparent from the description
to follow, the undergarments of this invention comprise
a front pieoe for covering the lower abdomen, a rear
piece for covering the buttocks and a connector piece
interconnecting the front pisce and the rear piece for
covering the crotch. ~he ~ront piece and the rear
piece are stitched to each other a-t their opposite
upper side portions. Indlcated at Kl, K2 and K3 in
; ~ig. 2 are the ~seams of the undergarments of the ~eep
type, medium type an~ shallow t~pe, respectively,
between the opposed upper side portions of the front

piece and the rear piece. The seams Kl, K2 and K3 have
their upper ends on the vertical line l~ and extend
rearwardly obliquely downward. The seam Kl corresponds
to the line K dra~n on the model segment 'r. Since the
seams Kl, K2 and K3 are located predominantly forward
from the center line N snd extend approximate~~y in
-~ parallel to the line 2R, the seams appear graceful.
Fig. 6 shows cut component ~ieces for making
an undergarment of the shallow type. Figs. 10 to 12
show the~unde~rearment of the shallow type worn on the
hu~an body. ~he undergarment 1, such as panties, briefs
or the like, comprises a~front piece 2 for oovering the
. ::~ : :
lower abdomen, a rear piece 3 chiefly for covering
the buttocks,~and;a connector plece 4 interconnecting
15~ the front ~iece~2 and the rear~piece 3 for covering
the crotoh. '~hese~pieces 2 to 4 are most preferably
made of a stretchable kni~ted fabric. However, other
knitted ~abrlosj woven fabrics or nonwoven fabrics
~- are ~imllarly usable.
The front ~1eoe~2 has~ projections 21 at its
;~ up~er opposite~side portions.~he projections 21
extend slightly obllquely~upward~and termlnate at ends
24 whl~ch are~inolined~upward toward~ the center line of
the front pieoe ~2. ~he front piece 2 has a gently~
curved upper~edge~25 ~hloh ls recessed most greatly at
: :

the midportion. The front piece 2 has a vJidth pro~res--
sively decreasing downward. l;he side edges 22 of the
front piece 2 are curved inward in conformity with the
groin between the thigh and -the abdomen or with a art
slightly above the groin. ~he lov~e end 23 of the
front piece 2 and one end 41 o~ the connector piece 4
are curved in conformity with each other and stitched
together.
~he rear piece 3 also has proaections 31
extending outward from its upper opposi-te side portions
obliquely upward. The projections 31 have ends 34
slanting upward toward the center line of the rear piece
3. The rear piece 3 has an upper edge 35 which is so
curved that it is recessed most greatly at its midportion
when seen in its entirety. When seen in detail, the
upper edge 35 is defined by a very slightly and gently
projecting curve at each side o~ its midportion ana
extends obliquely upward where it corresponds to the
upper edge of the projection 31. ~he rear piece 3 has
edges 32 extending from its lower to side portions and
curved in conformity ~vith the curves of the buttocks.
~he area and shape of the portion of the rear piece 3
surrounded by -the edges 32 are determined in accordance
v~ith the bulglng degree and contours of the buttocks.
~he ends 24 of the projections 21 of the

~52~ ~
14
front iece 2 are stitched to the ends 34 of the
projections 31 of the rear piece 3 as seen in ~ig. 7,
~hereby ~ortions for covering the lateral regions C are
~ormed. As already described, the bulges o~ the buttocks
B and lateral regions C of the human body can be ~iscussed
~ith reference to the truncated cone segmen-t T serving
a5 a model. The upper edge E of the cut piece completely
covering the peripheral surface of the segment ~ is
defined by a circular arc curve which is most greatly
recessed at its midortion. Similarly the upper edge
35 of the rear piece 3~is also~clrcular arc when seen
in its entirety. Accordingly it will~be readily
understood that ~hen an undergarment inoluding the rear
piece 3 is worn, the rear iece 3 completely covers
the buttocks 3 and the lateral re~ions G and tha-t the
~: :
~ upper hem of the undergarmen-t, i.e. the upper edge 35
: ~ :
of the rear piece 3~ is positioned atraight horizontally.
Althou~h the truncated cone segment ~ showrl in Fig. 4
corree,ponds to an under~arment o~ the dcep type, the
concept is exactly true of underearments o~ any depth,
so that the model seg~ent ~, when having a reduced
height, is similarly use~ul for undergarments of the~
shallow type. Wlth~rs~erence to L~lg. 7, the center line
Ul of the front piece 2 is vertical, while the center
line U2 of the rear ~iece 3 is inclined. When the
: ~ :

25~
undergarment made is v~orn, the center line U2 also isin a vertical position. It will be readily understood
from r`ig. 7 that ~hen the center line U2 is vertical,
the rear piece 3 is bulged out~ard. The slight and
~entle curves of the upper edge 35 of the rear piece 3,
which are in conformity ~ith slight and gentle
undulations of the human body, may be designed in
accordance with the Iorm of the human body. Based on
the same concept, the upper edge 25 of the front piece
2 is also gently curved, wlth the projections 21
inclined obliquel~ upward, because the projections 21
are also adapted to cover the bulging lateral regions C,
:
Viith reference to Figs. 4 and 5, the cut piece
for covering the peripheral surface of the segment T
other than the portions J has ends H slanting upward
toward the center line. The end H appears as the seam
Kl in Fig. 2 tthe same is true of'-the seams K2 and ~3).
By sui-tably determining the an~le of inclination of the
ends 24, 34 of the projections 21, 31 of -the front and
rear pieces 2, 3, such seams can be made to incline
forwardly upward appr~Y~imately in parallel to the line
QRs as indicated at K3. Since the length of the
rear piece 3 between the ends 34 is much larger than the
- ~ length of the front piece 2 between the ends 24, the
s am K3 appears at a ~ocatlon on~the ~ide closer to
: ~

1~525
16
the lo~er abdomen as shor~ in Fi~. 2.
The other end ~2 of the connector piece 4
is define~ by two e~ges slanting out~Tard toward the
center line thereof. ~he central lower end 33 of the
rear piece 3 to be stitched to the end 42 is defined by
two edges slanting upward ~oward its center line. ~hese
ends 33 and 42 dlffer ln the an~le of inclination, such
that the ends 33 and 42 define a space 5 therebet~een
when placed in buttln~ relation to e~c'n other before the
rear piece 3 and the co~nector ~iece 4 are stitched
together, as seen in Flg~ 6. The space 5 has a ~rogress-
ively increasing width to~ard the center line thereof.
The rear piece 3 and the connector piece 4 are
.
stitched together at the opposed ends 33 and 42 while the
lower end portion 33 is being stretched toward the
connector ~iece 4 most greatly along the ce~ter l~ne o~
the rear piece 3 and to a progressively lesser e~te~t
from the center line tow2rd the opposite sides thereof.
Since the rear piece 3 iQ thus stretched most ~reatly on
its center line, the garme~t 1 formed has a~ elon~ated
de~resslon 5 extending vert1cally on the center line of
.
the rear piece 3 a~d conforming to the gluteal cleft
between the buttooks. On the~opposi~e sldes OI the
depression 6, the rear~piece 3 has rounaed portions ln
conformit~ with the bulges of the buttocks since the

60 ~ons~quently the rear piece 3 of the undergarment 1
covers and supports the buttocks in intimate contact
therev~ th, feels s~ooth and comfortable, and fits
snugly to the curvés of the buttocks and gluteal cleft,
gi~Ting a graceful appearance.
~ he lower ënd 33 of the rezr piece 3 and the
end 42 of the connector piece 4 to be stitched there~o
-may be arcuated as shown in ~ig. 9. Inthis case, the
s~ace 5 formed between the ends 33 and 42 also hzs an
increasing width to~ard its cen~er and resembles a
crescent in sha~e. Q.lternatlvely the depression 6 can
be formed in an integ~al seamless piece of fabric
including the rear piece 3 and the con~ector piece ~, by
drawing the inte_ral piece into a fold at the portion
thereof corresponding to the junction of the zbove-
mentioned ends 33 and 4~ so that the rear ~iece portion
o~ the integr?l piece will be stretched most greatly on
its center line, and flxl~g the folded portion sult2bly
by s~itching. In tkis case 9 the front piece 2 may be
integral ~ith or separate from the co~nector piece 4.
When desired, a stretchable and decora~ive
tape 7 may be stitched to the upper edges 25, 35 of the
front and rear pieces 2, 3 to be fitted aro~d the ~:æist
and also to the side edges 22, 32, 43 of the front 2nd

rear pieces 2, 3 and the connector piece ~ to be fitted
aro-una the legs. I'he tape 7 is made partially or
entirely from stretachable yarns, such as rubber yarns
or spandex yarns ! by knitting or weaving. When the tæpe
7 attached to the above-mentioned edges has suitable
elasticity, the up~er hem of the undergarment provided
by the upper edges 25, 35 becomes straight while the
undergarment has bulging portions for covering the
buttocks and the lateral regions.
Flg. 8 shows the component pieces of under-
garments of the deep type 3nd the medlum depth type.
~he fron-t piece, rear plece and connector piece
constituting the undergarment of the deep type are
indicated in solid lines and designated at 28, 38 and
48 respectiveIy. Indicated in broken ~ines are the
component pieces of the undergar~ents of the medium
depth type, namely, front piece 29, rear piece 39 ænd
connector piece 49. ~he projec-tions, enas and edges
of the.se component pieces, ænd the space are referred
to by the same reference numerals as the correspond-
ing parts of the undergarment of the shallow type
shown in Flg. 6.
~ he rear ~leces 38, 39 ol the garments of the
deep type and the medium type also have projections 31

portions obliquely upward and terminating at ends 34
which are inclined upward toward the center line of
the rear piece. hach of the rear pieces 38, 39 ha~
an upper edge 35 which is curved inward most greatly
at its midportion when seen in its entirety. ~he
projections 31 of the medium type are wider than
those of the shallow type. ~he projections 31 of the
deep type are largest so that the upper edge 35 will
reach the waist. ~'he deep type, the medium type and
the shallow type are larger relative to one another
in the order mentioned in the length of the rear piece
between the ends 34 thereof.
The ~ront piecés 28, 29 also have projec-tions
21 extending outward from their upper opposite side
portlons but not inclined upward. ~he projections 21
have ends 24 inclined upward toward the center line
of the front piece. The front piece 29 of' the medium
type is larger than that of` the shallow type in the
~width of t~e projections 21 and has a horizon-tal
straight upper edge 25. The portion of the front
piece of the deep typ~ including the projections 21
::
extends largely up~Yard, and the projections 21 have
a very large width. Unlike the shallow type, the
front piece 29 of the deep -type has an upper edge 25
curved to project upward most greatly at its midportion.

~he shallow type, the medivm type and the deep type
are larger relative to one another in the order rnentioned
in the length of the front piece between the ends 24 of
the projections 21. The other ~arts of -the front
~iéces 28, 29, the rear pieces 38, 39 and the connector
pieces 48, 49 are almost similar in sha,e to the
corresponding parts of the undergarment of the shallow
-type. The front p ces 28, 29 and the rear pieces 38,
39 are stitched together at the opposed ends 24 and 34.
~he lower ends 23 of the front pieces 28, 29 are
i
stitched to the ends 33 of the connector pieces 48, 49.
The lower ends 33 of~the~rear pieces 38, 39 are
stitched to the other ends 42 of the connector pieces
; ' 48, 49. Thus in the same manner as the undergarment
of the shallow type, undergarments of the deep type
and the medium type are prepared.
; Vlhen the undergarments of the deep and medium
type~ are worn, -the upper hems 35 will be posi,tioned
horizontally straight slnce the,edgea 35 of the rear
;~ 20 pieces 38, 39 are curved inward most greatly at their
midportions. ~he front pieoe 28 of the undergarment
of the deep~type~is large- enough to fully cover the
entire~lov~er abdomen D~bulging forward. With the front
piece 28 bulged forward along the lower abdomen D, the
upper edge 25 becomes horizontally straight which edge

is curved outward most greatly at its midportion. The
upper edge 25 is then positioned at the same level as
the upper edge 35 of the rear piece 38. The front piece
29 of the undergarment of the medium depth type covers
the lower half of the lower abdomen D, with its upper
edge positioned intermediately between the position of
the upper edge of the deep-type garment and that of
the upper ed~e of the shallow-type garment. Since the
front piece 29 bulges in conformity with the bulges of
the;lateral regions C and the bulge of the lower
abdomen D, the straight upper edge 25 slightly lowers
in its entirety to assume a straight position. The
upper edge 25 is positioned at the same level as the
upper edge 35 of the rear piece 39.
With the undergarments of the deep and medium
types, the seams Kl, ~2 between the opposed ends 24, 34
o~ the front pieces 28, 29 and the rear pieces 38, 39
appear as lines slanting forwardly upward when seen
sideways, as iB the case with the garment of the shallow
type. These seams Kl, ~2 are positloned some distances
rearwardly away from ~e seam ~3 in corresponding relation i~
to the shortened lengths of the rear pieces 38, 39
between the ends 34.

and the deep t~pe. When the garments comprising these
components as stitched together are worn, the upper
edges 25 of the front pieces 20, 29, 28 and the upper
edges 35 of the rear pieces 30, 29, 38 are lowered to
the positions of the horizontal lines ~3, ~2, L1,
respectively ? as indicated by arrows owing to the
bulges of the buttocks, lateral regions and lower
abdomen. ~he side edges 22 of the front pieces 20, 29,
28 and the side edges 32 of the rear pieces 30, 399 38
,
are also lowered as 1ndicated by arrows. The gentle
undulations of the upper edges 35 of the rear pieces
30, 39 and 38 are not sho~n in Fig. 13.
