Henry E. Peters, Seattle, Wash.
,Application March 16, 1937, Serial No. 131,140
4 Claims. (01. 155-29)‘
-This invention relates to chairs, and particu
larly ?exible chairs with movable parts, that may
be shifted into various positions by an occupant
seated therein, for healthfulsupport of the body.
,5
It is assumed and believed, that in most kinds
of physical deformity, the skeletal tissue of the
body is misaligned and irregular, and that the
circulation within and function of the parts so
affected are relative to the nature and degree
‘10 of the skeletal'articular misalignment. Numer
ous maladies are attributable frequently to» skele»
tal misalignment and visceral displacement.
Itis therefore an object of this invention to
provide a chair with a movable back and other
' l5 movable parts, to form ?t the body, upon which
the body may be supported in various positions,
to relieve visceral displacement and skeletal mis
alignment, and to prevent undue pressure and
gles, for easing affected parts of the body into
their natural positions, for relieving visceral dis
placements, and so that the body may be gently
stretched to facilitate complete relaxation of the
muscles.
With these and other objects, that will here
5
inafter appear, I have illustratively exempli?ed
my invention by the accompanying drawings, of
which:
‘
Figure 1 is a side elevation, with parts broken 10
away.
.
Figure 2 is rear elevation of the chair, with the
back elevated.
’
Figure 3 is a bottom plan.
Figure 4 is a side elevation partly in section, 15
with parts of teeth broken away, and with the
back lowered and foot rest elevated.
Figure 5 is a front elevation, taken on line 5——5

Figure 8 is a detail side; view of the rear seat,
with elevated front and side portions, for sup
in section enlarged and taken on line 8--8 of Fig
porting theweight of the individual in healthful
positionsjon‘said seat. It is also an object to
30 mount said seat in slidable relation, in front of
the movable back member of said chair, and to
adjustably connect said back and seat, to provide
constant contact with certain parts of the body,
while thepositions of the parts of said chair, are
35
changed.
'
~
It is a further object to provide such a chair
pivotally mounted on an axle, and to so adjust the
position of the parts of said chair, so that the
center of the weight of the body thereon will
40 remain substantially over such axle, while the
positions of the chair are Varied.
It is also important on occasions that the body
be brought into various recumbent positions,
sometimes with the head portion'thereof in a
45 lower position than the foot portion, to relieve
visceral displacements, and. for relaxing the mus
cles of the abdominal and pelvic regions, and to
relieve or prevent congestion therein. It is there
fore among the objects of this invention. to pro
50 vide such an adjustable chair, whereby the upper
faces thereof for contact with a body,‘ may be
brought into various planes, said chair to be also
supported adjustably over said axle for lowering
either the head or foot portion, while the face of
55 said chair is on a single plane, or on various an
ure 6, and
.
Figure 9 is a detail view enlarged of the rear
seat, partly in section, taken on line 9--9 of Fig- 30
ure 8.
Like characters on the different ?gures repre
sent like parts.
'
An outside supporting frame is generally indi
cated as A, and formed of bottom side rails I 0, 35
posts 12 at corners, top side rails l3, and cross
braces l4. Inner top rails l5 are attached to the
posts, and are provided with notches l6 and I1,
along the top edge for supporting other movable
parts. The frame is mounted on casters for mov- 40
ing the chair on a floor.
Operative hand wheels l8, are mounted on the.
ends of a cross drive shaft 19, which is rotatably
supported in ordinary journals 2|, affixed to the
rear posts. Drive pinion gears 20, are-attached 45
to the shaft. A back member, generally desig
nated as B, is formed of parallel rails 24, con
nected by slats 25. On the rear lower edges of
these rails are a?ixed curved sectors 26, provided
with rack teeth 26', on the central portions there- 50
of, which mesh in the teeth of the pinion gears,
for shifting the positions of the chair when the
hand wheel is manually turned.
The back and rails 24, are pivotally supported
on a cross axle 21, and the endsi of the axle are 55
2 .
2,146,191
supported in said notches l1. A tie rod 28, con
nects the rails 24, and the body of said rod be
tween the rails provides lifting ‘bearings 28'.
Cross rods 29 and 30 also connect the sectors,
and serve to! actuate arms for elevating the foot
portions of the chair. Rods 3| attached to the
upper rear edges of the rails 24, provide guides
Further provisions are made for the support
of the feet and lower extremities of the individ
ual, as follows: Extension rails 41 are pivotally
connected at their upper ends onto the front
cross rod 31, and provided with a central cross
rod 48 and also with a lower rung 49 for a foot
rest, between the lower ends of the rails. Rings

for another cross rod 32, which is provided with
loops 33, on the ends thereof, for slidable dis
cupant seated upright, and prevent the arms 22,“

arms 22, while the chair is tilted into positions
Operative arms 52 are pivotally connected at
their front ends to the cross bars 48, and are
held in spaced relation by rod 52’. The rear ends
of the arms are provided with notches for ad
are pivotally connected at their rear ends to said . justable placement over either of the sector rods '
axle 21, and their front ends are supported on
a cross bar 35, which extends therethrough, with
the ends thereof normally resting in said notches
it, in top of the frame. Seat runners 36, are
slidably mounted over the guides 34, with their
front ends pivotally supported on the ends of
a cross tie rod 31. Another tie rod 38, maintains
the runners suitably spaced and moves said run
ners attached thereto. Mounted over the front
end of such runners 36, is a front section 39, of
a seat also designated, as C; and mount-ed over
the rear end of such runners is the principal or
rear section 49, of the seat, also indicated as Ca'.
An auxiliary back member of sheathing, D, is
slidably disposed on the front face of the mem
ber B, and adjustably connected by links 4|, to
29 or 39, for various elevations of the foot rest.
When said sectors’are rotated, the said arms 52 20
are pushed forward or drawn back, and the front
extension rails and foot rest carried to various
positions desired, as illustrated in Figures 1, 4
and 7.
,
The rear seat section 40, has its top face hol 25
lowed out at the rear portion, with a concave
depression 51, to conform with the ordinary
shape of the muscles of the upper portion of the
thigh, and with a short supporting central ridge
58, at the front of the depressions to support the 30
pubic structure between the thighs. Said depres
sion gradually slopes upward to the highest por
tions of the seat as at 59 on the sides, and at
69 in front to support the principal weight of
rails 42, by pins 45,. A series .of holes 46, through
the links, provides for adjusting the distance be
the body. The rear. edge of this seat is lower
than the front portion and is as low as the lowest 35
portion of the face of the seat, and is spaced
from the lower end of the auxiliary back and in
tween the member D and the rear .of seat 49, to
conform with requirements of persons of differ
ent size. Between the side rails 42, of the back
body beneath the spinal column, and to so re
lieve from pressure beneath .the hip joints and 40
the rear ends of said runners by the said cross
rod 38. The links are pivotally connected to the
D are ordinary slats 43, and a special panel 44,
to ?t the back of the individual, is suspended by
pivot rod 44’ extended into the rails 42.
Arms 50, are pivotally connected at their front
ends over the cross rod 31, and extend back
ward and their rear ends provided with eyes 5|,
which connect with the lower portions of the back
rails 24, by pivotal mounting over said lugs 28’.
The arms 59, are provided with a central tie rod
50 56'’. Thus when the back of the chair is low
ered, the arms 59, are pushed forward, and the
cross rod 31 and front ends of the runners with
the seats are moved forward and upward. Si
multaneously, the links are drawn forward by
said rod 38 and the auxiliary back is thereby
drawn downward, both without changing, the po
sition of the back or seats on the body of the in
dividual, who is moved with said seats and back,
60 with his center of weight over the axle.
The front seat section. 39, is connected over
the runners by pivotal contact with the rod 31,
and the rear section of the seat 40 is adjustably
connected over the runners and the cross rod 38,
65 by sets of pins 49’, which are projected through
and below such seat and span said rod 38. Seat
section 49 is also provided with bracket legs 55
which extend down from the rear portion there
of, for tilting the said seat section. When the
back of the chair is lowered to positions shown
in Figures 4 and '7, the cross rod 29 is moved for
ward by the sectors 25 and impinges against the
lower ends of said brackets, and thereby tilts the
face of the seat section 49, to conform with the
75 natural position of the body resting thereon.
position to escape the principal weight of the
on the lower spine. When the back and seat
are tilted as before described, the same contact
with the body is maintained.
I
When the several parts of the chair have been
‘shifted to provide an approximate horizontal 45
plane, as in Figure '7, the several parts of the
chair no longer move individually, .but as the
back is lowered still further the central parts of
the chair and the front end all rotate together
as a whole over the axle 21, and the body will
.50 .
lie in a recumbent position thereon, stretched out
thereon in natural position, with every part of ;
the body supported by the face portions of the
chair while approximately balanced on the axle.
The various positions of the ‘chair may be easily 55
obtained by the operations of the hand wheels,
turned by the occupant, in whatever position he
may be on the chair. Dotted lines are shown in
several of the ?gures, with like numerals to illus
trate shifted positions of the several parts of the 60
chair when the hand wheel is rotated to various
positions. It will be noted that when the chair
has been turned to position shown in Figure 1,
that the lower endsof the back rails 24, will have
contacted the cross bars .35, and raised them 85
from the notches l6, and thus elevated the for
ward portions of the guides 34, and seat runners
and seats, to form ?t beneath the back of the
individual recumbent thereon.
70
It will be understood that when the back of
the chair is disposed approximately perpendicu
lar, that the rear edge 'of- the seat 49 is approxi
mately over the axle 21, and the weight of the
body balanced thereover, permitting easy move‘
2,146,191
ment of the chair. Again when the chair back
is lowered, said seat is moved forward, and the
individual is also carried forward thereby, and
by the sliding auxiliary back, and the weight of
the individual continued approximately balanced
over the axle, with the body supported partly by
‘the seat and partly by the said back. The space
between the rear seat and the lower end of the
back at all times prevents any pressure against
the lower end of the spine from the rear thereof.
vThis ?exible chair provides means for both
exercise and relaxation of the various portions
of the human body, and the inventor has demon
strated by the actual use thereof, that it is both
practical, and amazingly bene?cial for the pur
poses for which it was designed and constructed.
While for the purposes of explanation I have
" shown certain detailed construction, yet my in
