Definitions

  • the present invention relates to a sitting device used for sitting on flat surfaces and that device is able to prevent spinal diseases, such as cervical, thoracic, and lumbar diseases, to occur.
  • Zafus is one of those. Stuffed with fluffy, soft, downy materials, a zafu raises the hips and partially absorbs the reaction force generated by the floor under the gravity force of the body of a sitter, making sitting in a leg-folding posture or the crossed-legged posture, a.k.a. Lotus sitting posture, more comfortable.
  • a zafu does not provide a stable support; the sitter's pelvis can tilt forwards and backwards freely, eventually causing back pain and other spinal problems.
  • That sitting device must provide stable support that keeps a sitter's pelvis always in its neutral position, allowing the sitter to stay in a correct sitting posture.
  • the sitting device therefore, is able to prevent many spinal diseases related to wrong sitting postures including cervical, thoracic, and lumbar diseases. It is an object of the present invention to provide such a sitting device.
  • the sitting device comprises a padded member, a thin pad extended forwardly from the padded member, and a hard block fully inserted inside the padded member.
  • the padded member has a generally right triangular shape, and is made of resilient materials such as foam, rubber, or cotton to make the device comfortable to sit on.
  • the hypotenuse surface of the padded member is undulating ergonomically to ensure extra comfort for the sitter.
  • the area of the hypotenuse surface of the padded member together with the area of the thin pad is wider than the total area of a sitter's buttocks, upper legs, and knees, so that the sitter can sit, in a leg-folding posture, fully on the sitting device without any part of his body touching the flat surface.
  • the hard block is made of a non-resilient material such as wood, polystyrene foam, or hard rubber. The hard block is able to tolerate, without rupturing, the gravity force on a mass of an adult's body with a shape and size similar to those of the adult's buttocks.
  • the hard block is inserted completely inside the right angle area of the padded member.
  • the height of the front side of the hard block is greater than the distance from the lowest point of the sitter's coccyx to the lowest point of his tuberosity of ischium.
  • Both the padded member and the hard block have a flat bottom side to ensure stability.
  • a sitter needs to sit in a leg-folding sitting posture; in which, his buttocks are on top of the highest portion of the padded member, his upper legs lie along the hypotenuse surface of the padded member, and both of his left and right lower legs must rest inside the thin pad and fold along the long side of the thin pad and the right one is on top of the left one.
  • the sitter can also sits in a cross-legged sitting posture a.k.a. Lotus sitting posture.
  • the sitter needs to adjust his buttocks so that his sacrum and coccyx are elevated by the top part of the hard block, and his ischium stays close to the front side of the hard block.
  • FIG. 1 is a left perspective view of a sitting device for prevention of spinal diseases according to the invention.
  • FIG. 2 is a right perspective view of the sitting device shown in FIG. 1
  • FIG. 3 is a cross-sectional view of the sitting device of FIG. 1 along the line A-A′ shown in FIG. 2
  • FIG. 4 is a cross-sectional view of the sitting device of FIG. 1 along the line B-B′ shown in FIG. 2
  • FIG. 5 illustrates how to use the pillow of FIG. 1
  • the present invention provides a sitting device that is used for sitting on flat surfaces.
  • the sitting device is able to keep a sitter in a correct sitting posture by keeping his pelvis always in its neutral position.
  • the sitting device 100 comprises a padded member 200 , a thin pad 300 extended forwardly from the padded member 200 , and a hard block 400 fully inserted inside the padded member 200 .
  • the padded member 200 has a generally right triangular shape, and is made of resilient materials such as foam, rubber, or cotton to make the device 100 comfortable to sit on.
  • the hypotenuse surface 201 of the padded member 200 is undulating ergonomically to ensure extra comfort for the sitter.
  • the area of the hypotenuse surface 201 of the padded member 200 together with the area of the thin pad 300 is wider than the total area of a sitter's buttocks, upper legs, and knees, so that the sitter can sit fully on the sitting device 100 without any part of his body touching the flat surface.
  • the hard block 400 is made of a non-resilient material such as wood, polystyrene foam, or hard rubber.
  • the hard block 400 is able to tolerate, without rupturing, the gravity force on a mass of an adult's body with a shape and size similar to those of the adult's buttocks.
  • the hard block 400 is inserted completely inside the right angle area of the padded member 200 .
  • the height H indicated in FIG.
  • a sitter needs to sit in a leg-folding sitting posture in which, his buttocks are on top of the highest portion T, indicated in FIG. 3 , of the padded member 200 , his upper legs lie along the hypotenuse surface 201 of the padded member 200 , and both of his left and right lower legs must rest inside the thin pad 300 and fold along the long side L, indicated in FIG. 2 , of the thin pad 300 , and the right one is on top of the left one.
  • the sitter can also sits in a cross-legged sitting posture a.k.a. Lotus sitting posture.
  • the sitter needs to adjust his buttocks so that his sacrum is elevated by the highest area 401 , his coccyx rests on the plateau area 402 , and his ischium stays close to the front side 403 of the hard block 400 . That way, his pelvis is always “locked” in its neutral position, making the sitter sit in a correct posture which prevents spinal diseases related to wrong sitting postures including cervical, thoracic, and lumbar diseases to occur. If there were no hard block 400 inserted inside the padded member 200 as described, the sitter's pelvis would tilt freely, leading to wrong sitting postures.
