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 strain on the various muscles of the body and . of Figure 1, with a portion of the back and bot~ 20 to relax the same, while the various positions of tom enlarged. 20 the chair are varied. ‘ Figure 6 is a perspective detail view of the rear A further object is to provide such a chair seat, with fragments of adjoining parts. with a seat member constructed with a depression Figure 7 is a side elevation, with front and back in the rear portion of the top face thereof to» con portions substantially level, with parts broken ‘25 form‘to the shape of the muscles of the upper away or omitted. 25 portion of the thighs and buttock, and provided 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 position .over curved arms 22. These arms 22, are 55 may be carried over the rungs for stirrups into . which the feet may be inserted, when the person is recumbent on the chair .and desires to stretch pivotally connected at their rear ends, to the rear ends of the top rails l5, and are prevented by said loops from spreading outward when used by oc .as shown in Figures 4 and '7. 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,“ 15 from moving, when used for stretching the body, in position shown in Figures 4 and '7. 34 represents guides for supporting seats and 10' his body between such stirrups, and the curved 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 3 slidably mounted over said guides in front of said sheathing and connected in pivotal relation by links therewith and adapted to move forward when said sheathing and back are lowered, and adapted to move backward when said sheathing and back are raised for maintaining constant contact with ?xed positions on the back and thighs of the occupant of said chair while the po sitions of the chair are varied, with means for moving said chair back and axle on said frame. 3.
