DETAILED DESCRIPTION

(11) Techniques are discussed herein for providing seating guidance to a person sitting on a seat, e.g., of a chair, stool, etc. For example, a device may be removably placed on and attached to a seat, and may provide a barrier on each side of a person's legs while sitting on the seat. The barriers may provide tactile and proprioceptive input to the person so that the person is cued as to where the person's legs belong, e.g., for a desirable and functional learning posture in a chair. An example chair cover has a back portion and a set portion. The back portion may be a fabric tube that fits over (e.g., slides over, or can be wrapped around and secured) a back of a chair. The seat portion can be fastened to the chair and provides raised leg guides that resist outward movement or excess abduction of the person's thighs. The guides may provide sensory input to the person, e.g., proprioceptive, vestibular, and/or tactile input to the person. These examples, however, are not exhaustive.

(12) Items and/or techniques described herein may provide one or more of the following capabilities, as well as other capabilities not mentioned. Proprioceptive, vestibular, and/or tactile input may be provided to a person sitting on a seat (e.g., of a chair, stool, etc.). A seating aid may provide guides to indicate to a person where the person's thigh or thighs belong for a desired, e.g., a learning-ready, sitting position. Focus and attention of seated person's may be extended. Proper posture while seated may be encouraged. A time duration that a person is able to sit may be extended. Fidgeting of a person while seated may be reduced. Desired (e.g., appropriate, functional, and/or expected) sitting positions may be encouraged. Undesired sitting positions (e.g., side sitting, sitting on a person's legs or feet, sitting on an edge of a seat, sitting with an undesirably small amount of a person's gluteus maximus on a seat, etc.) may be passively discouraged by a mechanical seating aid. Person's with ADHD, autism, and/or ADD (attention deficit disorder) may be able to sit for longer periods of time and/or with greater focus, e.g., due to being passively reminded to stay in a more stable position on a seat with decreased prompt dependency from another person. Other capabilities may be provided and not every implementation according to the disclosure must provide any, let alone all, of the capabilities discussed. Further, it may be possible for an effect noted above to be achieved by means other than that noted, and a noted item/technique may not necessarily yield the noted effect.

(13) Referring to FIGS. 1 and 2, a seating aid 10 is configured to be removably attached to a furniture item 12. Here, the seating aid 10 is attached to a seat 14 of the furniture item 12. The furniture item 12 in this example is a stool, having the seat 14 and legs 16 (portions of three of which are shown in FIG. 1), although the seating aid 10 may be used with other types of furniture items, e.g., chairs, etc. The seating aid 10 is configured to provide sensory input to a person 18 sitting on the seat 14. In particular, the seating aid 10 is configured to provide resistance to outward movement of thighs 20 and/or abduction of hips 38 of the person 18. The seating aid 10 includes barriers 22, an attachment mechanism (here, attaching straps 24), and a separator 26. The seating aid 10 is configured to provide an aperture 28 when attached to the furniture item 12 to allow the person 18 to sit on the seat 14, here in direct contact with the seat 14 except for where the separator 26 separates the person 18 from the seat 14.

(14) The barriers 22 are configured and disposed to provide guides to the person 18. The barriers 22 may be called guides, or rails, or bumpers, or lateral movement impediments, etc. The barriers 22 may provide sensory input to the person 18, e.g., to help direct or cue the person 18 to a desired sitting position. Also or alternatively, the barriers 22 may provide proprioceptive input to the person to help the person appreciate an orientation of the person (e.g., help provide stability guidance to the person 18). Also or alternatively, the barriers 22 may provide proprioceptive input to help the person 18 understand the person's sense of relative position (e.g., with respect to the furniture item 14, with respect to the earth, etc.).

(15) The barriers 22 are sized to interfere with and/or impede abduction of the thighs 19 outwardly from a midline of the person 18. For example, the barriers 22 may be configured to extend at least about two inches (2 in.) (about five centimeters, 5 cm) above the seat 14 when the seating aid 10 is disposed on the seat 14. The barriers 22 may be configured to extend other distances from the seat 14, e.g., at least about 4 in. (10 cm), at least about 10 in. (25 cm), at least about 11 in. (27.5 cm), at least about 12 in. (30 cm), etc. Other sizes (e.g., heights) of barriers 22 may be used. Also, the barriers 22 may extend approximately parallel (e.g., parallel ±10°) to a centerline 30 of the furniture item 12 when attached to the furniture item 12, and/or may extend approximately perpendicular (e.g., perpendicular ±10°) to a length of the separator 26. The barriers 22 may extend over a significant portion (e.g., 50% or more) of a front-to-back length 32 of the seat 14. The barriers 22 may extend over a length near a front 34 of the seat 14, while not extending close to a back 36 of the seat 14, e.g., where the hips 38 of the person 18 are preferably disposed.

(16) The barriers 22 may be disposed, when attached to the furniture item 14 to allow the person 18 to move while providing resistance to abduction of one or more of the thighs 19. The separator 26 may be of a length such that with the barriers 22 separated by the length of the separator 26, the aperture 28 is wide enough to accommodate the thighs 19 and the hips 38 of the person 18 while being disposed to provide lateral impediments to the person 18. The barriers 22 may be disposed such that barriers 22 will be in contact with the person 18 without abduction of the thighs 19, or with slight abduction of the thighs 19. For example, for use with preschool children, the seating aid 10 may be configured such that barriers 22 are separated by about 12 in. (30 cm). For use with children from first to fourth grade, the seating aid 10 may be configured such that barriers 22 are separated by about 13.5 in. (34 cm). For use with children in fifth or sixth grade and beyond, the seating aid 10 may be configured such that barriers 22 are separated by about 15 in. (38 cm). The barriers 22 may be disposed to provide tactile input to the person 18 as the person moves laterally, i.e., side to side on the seat 14. The barriers 22 may be disposed proximate to at least a portion of a perimeter of the seat 14.

(17) The barriers 22 may comprise one or more materials such that the barriers 22 are resilient, durable, and resistant to fraying or otherwise being easily picked apart. For example, the barriers 22 may be made of a durable rubber or foam that is not easily torn. Persons with autism, ADHD, and/or ADD may pick at the barriers 22 but the material of the barriers 22 makes picking at the barriers difficult. For example, each of the barriers 22 may comprise a fabric (e.g., cloth) tube with a rubber or other resilient material disposed in the tube.

(18) The separator 26 may be configured to help ensure a desired separation of the barriers 22. The length of the separator 26 used may be selected to help guide the person 18. For example, the length of the separator 26 used may have the barriers 22 hug (e.g., touching and biased against) the hips 38 of the person 18 without movement of the person on the seat 14. The length of the separator 26 used may have the barriers 22 touching the thighs 19 of the person 18 before abduction of the thighs 19, or may provide a space between the barriers 22 and the thighs 19 to allow for some abduction (e.g., an angular separation of the thighs 19 of 10°) before contact with at least one of the barriers 22).

(19) The separator 26 may be configured to facilitate the person 18 sitting on the seat 14. For example, the separator 26 may be made of a flexible material, e.g., a strap of woven nylon, to allow the separator to adjust to one or more contours of the seat 14, e.g., under the weight of the person 18. The separator 26 may be a durable, yet flexible material. Alternatively, the separator 26 may be a rigid material, e.g., a strip of plastic, to help ensure the separation of the barriers 22 and to retain the separation of the barriers 22 at the length of the separator 26. The separator 26 may be thin, e.g., less than half an inch (1.25 cm), less than a tenth of an inch (0.25 cm), etc. This may facilitate the person 18 sitting on the seat 14 without adding significant height to the seat 14 while being comfortable for the person 18. In other example implementations, one or more additional separators may be included as part of the seating aid 10.

(20) The attaching straps 24 are one form of an attachment mechanism configured to releasably attach the seating aid 10 to the furniture item 12. In this example, the attaching straps 24 are adjustable straps of material that may be fastened to each other and/or to the furniture item (e.g., buckled or fastened to the furniture item 12 or to each other under the seat 14), although other forms of fastening, e.g., depending upon the type of attaching mechanism, may be employed. The attaching straps 24 are configured to secure the seating aid 10 to the furniture item 12 so that the barriers 22 will be substantially fixed, being able to resist outward movement (i.e., away from the centerline 30) by the person 18. The barriers 22 may be able to move while the seating aid is attached to the furniture item 12, but are inhibited from moving such that the barriers 22 provide tactile input to the person 18 pushing against one or both of the barriers 22. The attaching straps 24 are attached at different points along lengths of the barriers 22 to help inhibit pivoting of the barriers 22. The attaching straps 24 are configured and disposed to secure the seating aid 10 to the furniture item 12 to inhibit lateral, side-to-side, movement of the seating aid 10 relative to the seat 14. The attaching straps 24 may inhibit front-to-back (or vice versa) movement (e.g., parallel to the centerline 30). Additional attaching straps (e.g., see FIG. 5) and/or one or more other features (e.g., see FIG. 6) may be included as part of the seating aid 10 to inhibit front-to-back (or vice versa) movement of the seating aid 10 relative to the seat 14. The attaching straps 24 in conjunction with the separator 26 is configured to secure the barriers 22 above the seat 14 such that the barriers 22 are disposed and held in place to provide abduction resistance to the thighs 19. For example, the attaching straps can be affixed to the furniture item 12 and/or each other and tightened such that the separator 26 is taut. The barriers 22 will thus be separated by the length of the separator 26, retained at this distance by the separator 26, and held in place to resist lateral movement by the person 18 to provide sensory input to the person in response to the person 18 moving one or more of the thighs 19 outward and/or moving one of the hips 38 away from the centerline 30.

(21) The seating aid 10 as shown in FIGS. 1 and 2 is an example only, and many other configurations of seating aids may be used. For example, seating aids with barriers of a variety of different shapes (i.e., differently-shaped barriers) may be used. In FIGS. 1 and 2, the barriers 22 have cylindrical shapes, with circular cross-sections. The barriers 22 thus extend away from the separator 26 (e.g., away from the seat 14) and toward the centerline of the seating aid 10 for the lower halves of the heights of the barriers 22 and away from the separator 26 and away from the centerline for the upper halves of the heights of the barriers 22. Referring to FIGS. 3-5, for example, seating aids 50, 52, 54 with barriers 60, 62, 64, respectively, with rectangular (e.g., square) cross-sections may be used. The barriers 60, 62, 64 extend substantially vertically away from separators 80, 82, 84 (e.g., within 10° of perpendicular to planes of the respective separators 80, 82, 84 when taut). Still other shapes (e.g., triangles, ovals, etc.) may be used.

(22) Other examples of barriers may be used in various configurations of seating aids. For example, while the barriers 22 shown in FIGS. 1 and 2 are monolithic, non-monolithic barriers may be used such as the barriers 62 that comprise multiple, separated, portions. As yet another example, barriers may extend at oblique angles relative to a centerline of a seating aid. For example, referring to FIG. 3, the barriers 60 extend at plus or minus an angle 66 relative to a centerline 68 of the seating aid 50. The angle 66 may be, for example, about 10° (e.g., 10°±2°), or about 15°, or about 20°, or another angle. In this way, the barriers 60 may be closer to the person's hips than to lower ends of the person's thighs or the person's knees as it may be desirable to restrict movement of the person's hips more than the lower ends of the person's thighs.

(23) Also or alternatively, various other types of attaching mechanisms may be used. For example, different forms of attachment mechanisms may be used. Referring to FIG. 4, for example, one or more attachment cords (or ropes) 71 may be used instead of or in addition to straps. Many other forms of attachment mechanisms may be used such as pairs of straps with buttons, snaps, or belt buckles to secure the straps to each other. For example, one or more pairs of nylon straps with each strap in a pair terminating with a mating portion of a side-release or quick-release buckle. Still other examples of attachment mechanisms include, referring to FIG. 4, a strap 70 and a loop 72 configured such that the strap 70 can be fed through the loop 72 and a first portion 74 of the strap 70 attached to a second portion 76 of the strap 70. For example, the first portion 74 may include hooks and the second portion 76 may include loops such that the first and second portions 74, 76 are parts of a hook-and-loop fastening mechanism. Other configurations may be used, such as the portions 74, 76 including halves of snaps, or a button and button holes, respectively, etc. More than one of the strap-and-loop combinations may be used (e.g., one or more for attaching the seating aid side-to-side to a seat and/or one or more for attaching the seating aid front-to-back to the seat). As another example attachment mechanism configuration, referring to FIG. 6, clips 86 may be attached to bottoms of barriers 88 and clips 90 may be attached to a separator 92 of a seating aid 94. The seating aid 94 is a U-shaped, rigid device although the barriers 88 may have a pliable outer surface. The clips 86 are configured to receive a seat 96 in apertures 98. The clips 90 are configured to receive posts 100, that extend from the seat 96 to a back rest 102 of a chair 104, by pushing the seating aid 94 onto the posts 100 from a back of the chair 104 (such that the separator 92 is disposed behind the posts 100). The clips 86, 90 may releasably attach the seating aid 94 to a chair 104. The clips 86 may be configured to position the barriers 88 above the seat 96. Alternatively, the clips 86 may not be used and the clips 90 may be used to position the barriers 88 above the seat 96.

(24) In addition to the attaching mechanism, one or more other features may be provided to help inhibit lateral motion of a seating aid (or at least lateral impediments of seating aids) relative to a seat. For example, slip-resistant material may be disposed on one or more surfaces configured to contact the seat, e.g., on a bottom of a seating aid, and/or on one or more surfaces of an attaching mechanism to help inhibit detaching of a seating aid once attached to a seat. For example, a slip-resistant sheet and/or slip-resistant patches may be disposed on a bottom of a seating aid.

(25) Still other configurations of seating aids may be used. For example, attachment mechanisms, separators, and/or barriers discussed, in addition to others not discussed, may be mixed and matched to form other seating aid configurations.

(26) Referring to FIGS. 7-10, a seating aid 210 includes a back 212, a base 214, lateral impediments 216, 218, and an attachment mechanism 220. The seating aid 210, in this example, is configured as a seat cover, and in particular a chair cover. The seating aid 210 may omit the back 212.

(27) The back 212 comprises a tubular sheath providing an opening 222 configured to receive a back 224 of a chair 226 (see FIG. 9). The back 212 may be configured such that the opening 222 is close to a size of the back 224 of the chair 226 such that the seating aid will snugly receive the back 224 to help retain the seating aid 210 in place relative to the chair 226 with the back 224 received by the opening 222. The back 212 of the seating aid 210 may be a fabric sheet folded over and sewn onto itself along sides 230, 232 of the back 212 to provide the opening 222.

(28) Alternatively, one or more of the sides 230, 232 may be opened and closed, e.g., by a respective zipper. A height of the back 212 may be such that the back 212 may fully receive the back 224 of the chair 226. A top 234 of the back 212 may be closed, providing a fixed maximum depth of the back 212. Alternatively, the top 234 of the back 212 may be open, or selectively opened (e.g., with a zipper) such that chairs with backs taller than the height of the back 212 of the seating aid 210 may be accommodated (e.g., extend out the top 234 of the back 212 of the seating aid 210).

(29) The lateral impediments 216, 218 may be tubes 236, 238 of fabric, e.g., the same fabric used for the back 212, with elongated members disposed within the tubes. For example, foam or rubber tubes or cylinders may be used as the elongated members and disposed in the 236, 238. The tubes 236, 238 may be sewn shut. Alternatively, each of the tubes 236, 238 may be openable on at least one end such that the tube may be opened to remove or insert the elongated member, and closed (e.g., by being buttoned or snapped or zipped shut). The tubes 236, 238 may be sewn or otherwise attached to the back 212. The base 214 may be a sheet of fabric, e.g., the same fabric used for the back 212. The base 214 is attached to the back 212, and the back 212 and the base 214 may be formed from a single, monolithic sheet of fabric. The base 214 may be attached, e.g., sewn, to the lateral impediments 216, 218. The base 214 may be resistant to stretching such that the base, attached to the lateral impediments 216, 218 is configured to inhibit lateral motion of the lateral impediments away from a centerline 239 of the seating aid 210 with the base 214 pulled taut by the attachment mechanism 220. The base 214 has a small (e.g., not a significant) thickness such that the base 214 does not significantly raise a person sitting on the seating aid 210, when disposed on the chair 226, compared to the person directly sitting on the chair 226. For example, the base 214 may have a thickness of less than about a quarter of an inch (about 0.6 cm) or less than about 0.1 inches (about 0.25 cm).

(30) The attachment mechanism 220 is configured to releasably attach the seating aid 210 to the chair 226, and to pull the base 214 taut, to inhibit movement of the seating aid 210 relative to the chair 226 and thus to inhibit lateral movement of the lateral impediments 216, 218 from outward (side-to-side) lateral movement. The attachment mechanism 220 comprises a buckle arrangement including a pair of straps 202, 204 although more than one pair of straps may be used and/or other types of attachments mechanisms may be used. Here, the straps 202, 204 are configured to attach by a buckle arrangement, with the strap 202 providing holes 206 and the strap 204 including a buckle 208 affixed at an end of the strap 204 and configured to have the strap 202 passed through the buckle 208 and a pin 209 of the buckle 208 inserted through a respective one of the holes 206. One or more additional mechanisms, e.g., one or more additional buckle configurations could be attached to the base 214 to inhibit front-to-back motion of the seating aid 210 relative to the chair 226 although the use of the back 212 may sufficiently inhibit such motion. The base 214 may be sufficiently flexible and the combination of the attaching mechanism 220 and the base 214 sufficiently forgiving such that the base 214 may adapt to one or more contours of the chair 226 in response to a person sitting on the base 214. As shown in FIGS. 9 and 10, the seating aid 210 may be slipped over the chair 226 by sliding the back 212 of the seating aid 210 over the back 224 of the chair 226 in a direction 270 such that the opening 222 snugly receives the back 224 of the chair 226. The back 224 may comprise a material that is configured to stretch (e.g., Lycra®, Spandex®, etc.) to facilitate the back 224 being able to accommodate and snugly receive different sizes and/or shapes of backs of chairs. The seating aid 210 may comprise multiple materials, e.g., a fabric sheet with different portions of the fabric sheet comprising different fabric materials. Once the back 224 of the chair 226 is received such that the base 214 is in contact with a seat 240 of the chair 226, the attachment mechanism 220 may be used to pull the base taut and attach the seating aid 210 to the chair 226. A person may sit on the seating aid 210 in an aperture 242 provided between the lateral impediments 216, 218 and receive sensory input to help the person maintain desired seating position for extended periods of time.

(31) The seating aid 210 (or other seating aid) may include one or more further features. For example, a pocket 260 may be attached or included on a rear side of the back 212, e.g., for storage (e.g., for books and/or other school materials). As another example, a lumbar support (e.g., made of foam or other appropriate material) may be included in a front portion of the back 212 (e.g., in a front pocket of the back 212, or attached to a front wall of the back 212, possibly inside the opening 222). As another example, hanging mechanism 262 (e.g., a hook or a half of a hook-and-loop holder) may be attached to a rear of the back 212 such that an item may be hung to the back of the seating aid 210. For example, a name card or student chart may be hung from or otherwise attached to a rear of the seating aid 210.

(32) Example implementations of the seating aid 210 (but using the attaching straps 24) for use with children have been made.
