Field of Invention The invention relates to chairs, seats and the like for supporting a person in seated position.
2. Description of Prior Art Chairs commonly support the buttocks, thighs and back of the user but leave the lower limbs to depend from the chair seat. An alternate and more comfortable position for some is to sit on the floor in a cross-legged position as sometimes referred to as a one-half or full lotus position. Many people with poor circulation are required for medical reasons to elevate their legs while in a seated position and, in all instances, raising of the lower limbs reduces the work load on the hert. The problem is that many people, particularly adults who need the beneficial assist, find it difficult to sit in a cross-legged position where only the buttocks and feet are supported leaving the full limbs (thighs and crura) remain unsupported.
The ideal condition for a person at rest in a seated position is maximum physical relaxation of the body accompanied by minimum resistance to blood flow. This condition can be best obtained by the elimination of pressure points or areas of high physical stress.
SUMMARY OF THE INVENTION An object of the present invention is to provide a body support of the character described which will afford a full cushioned support of the body while seated in a cross-legged position with the feet and lower limbs positioned at substantially the elevation of the buttocks, and which will enable almost all persons including adults to assume and receive the benefits of this position.
Another object of the present invention is to provide a body support of the character above which will enable a person to sit most comfortably for long durations of time without tiring and without requiring the otherwise frequent periodic changing of position to shift weighted stress points of the body.
A further object of the present invention is to provide a body support of the character described which will maximize the area of support reducing to a minimum stress areas and obtaining a concomitant maximizing of the natural flow of blood and oxygen throughout the body.
The invention possesses other objects and features of advantage, some of which of the foregoing will be set forth in the following description of the preferred form of the invention which is illustrated in the drawings accompanying and forming part of this specification. It is to be understood, however, that variations in the showing made by the said drawings and description may be adopted within the scope of the invention as set forth in the Claims.

DETAILED DESCRIPTION OF THE INVENTION The body support of the present invention comprises briefly a first cushion portion 11 having a top surface 10 formed and dimensioned to receive and support the buttocks of a person when seated thereon; a pair of second laterally spaced cushion portions 12 and 13 contiguous to portion 1 l and extending in a normally forward direction therefrom and having top supporting surfaces 16 and 17 substantially flush with surface 10 and being dimensioned and positioned to support the users thighs; the lateral spacing of portions 12 and 13 and their forward extension from portion 11 defining a cavity 18 for the users feet when the user is sitting crosslegged on the support as illustrated in FIG. 1.
As may be best seen from FIG. 3, the laterally spaced cushion portions 12 and 13 diverge forwardly from the rear cushion portion 11 thus'conforming to the divergent extension of the thighs from the buttocks of a person seated cross-legged on the structure. Also the top surfaces 16 and 17 flare upwardly to the outsides of the cushions, as can be best seen in FIGS. 6 and 7, so as to conform to the elevation of the outside of the thighs of the seated'person. Finally, the lateral cushions 12 and 13 are preferably made of a length which will underlie and support the users knees and calves when the users legs are forwardly extended, as seen in FIG. 2. As a feature of the present construction, facilitating such alternate seated position, the top surfaces 16 and 17 are formed with breaks 21 and 22, see FIG. 3, positioned for underlying the users knees with the portions 23 and 24 of the top surfaces forward of breaks 21 and 22 sloping downwardly to underlie and support the calves of the legs of the user as seen in FIG. 2.
As an important feature of the present invention, the third cushion 26 is positioned forwardly'of rear cushion 11 and medially between cushions l2 and 13 and functions to divide cavity 18 into a pair of recesses 27 and 28 for receiving the users feet; and importantly the top surface of cushion 26 is at an elevation receiving and supporting each leg crus when the user is seated in cross-legged position with his feet positioned in recesses 27 and 28. To accomplish this support, the top surface of cushion 26 is substantially flush with top surface 10 of cushion 11.
Preferably cushion 26 is divided into a pair of'fore and aft spaced sections 31 and 32 individually compressible for individual leg crus support. This individual support holds the lower limbs from rolling or gravitating toward each other and enables a desired maintenance of at least some spacing between the limbs. Preferably aft section 32 is located substantially between the thigh supporting areas of cushions 12 and 13 and section 31 is spaced forwardly therefrom, generally forwardly of breaks 21 and 22. The full forward extension of cushion 26 is useful in accommodating persons of various leg lengths. A person may draw his ankle portions back close to the body or leave them further out as he may find most comfortable. Also the length of the central cushion enables freedom of movement in shifting the position of the lower limbs during long periods of repose on the structure. Relative compression of the several cushion portions will result in a support of the lowermost portion of the body at about the level of the buttocks which has been found to be most comfortable. The forward divergent tapering of the side cushions provides a forward widening of the feet receiving recesses 27 and 28 and the bottoms of the feet will assume a position generally parallel to the side cushions.
As another and important feature of the present invention, a back rest cushion 36 is positioned in elevated relation to cushion l1 and at the rear thereof for engaging and supporting the users back. Preferably, this cushion is formed with a normally forwardly disposed surface 37 curved and positioned to meet with and support the users back in the lumbar region. Also, preferably, cushion 36 is carried on a supporting frame 38 for vertical adjustment for optimal support of the users back. In this connection, the top surface of rear cushion 11 is provided with an upward flare extending to the rear of the cushion soas to assist in the proper rotation of the pelvis and correct erect positioning of the spine. The combination of this cushion shape and the back rest completes the body support with the whole body in balance and most comfortably supported for long duration seating.
The structure is preferably constructed as seen in FIGS. 5 8 on a base plate 41 which also furnishes the support for a pair of rear vertical guides 42 which telescopically receive the lower ends of frame 38 enabling the ready demounting of the back rest for portability, shipping and storage. The back rest cushion 36 may be adjustably attached to frame 38, to permit vertical adjustment of cushion 36, by manually operated clamps 43. A base cushion 33 is here mounted on plate 41 and has a trapizoidal opening in the front thereof filled with a softer cushion 34 which forms the bottoms of recesses 27 and 28. Cushion portions 11, 12, 13, 31 and 32 are mounted on the top side of cushions 33 and 34. All of the cushions are here made of foam plastic. Foams of different indent deflection are required. The softer foams do not support adequately yet are desired at points of body contact. Accordingly, sections of someshat denser foam are used in the base cushion and are built into the several suchion portions as for example see insert sections 46 and 47 in the laterally spaced cushions l2 and 13 and insert section 48 in the central cushions 31 and 32. The sectionalized structureis enclosed in an appropriate covering as the device is seen in FIGS. 1 3. The body support may be made in various sizes to accommodate various sized people; however as one of the features of the structure, one model will accommodate a significant range of body sizes.
The body support of the present invention may, in the form herein depicted, be mounted directly on the floor with the latter furnishing the flat surface support for the base cushions of the structure. Alternatively, the body support may be elevated on legs or other base supporting structure as in a conventional chair or the like.
