Definitions

  • the present invention generally relates to a chair, and in particular, to an orthopedic chair that is comfortable to use while being able to prevent spinal diseases including lumbar kyphosis, thoracic kyphosis, sacrum and coccyx misalignment, and herniated disc.
  • US Pat. No. 5,630,648 describes a chair with an adjustable seat back so that an occupant can achieve a 135-degree sitting posture.
  • the occupant's buttocks tend to glide forwardly, making the occupant have to put his feet on the ground at all time to bear the gravity of his body to keep his buttocks in place. Given that, it is not comfortable to sit on the chair.
  • Tilt SeatTM Eco chair is another invention, in which the seat is tilted forwardly so that an occupant can obtain a 135-degree sitting posture.
  • the chair does not have a seat back, the occupant actually tends to bend forward, potentially leading to spinal diseases such as herniated discs.
  • the present invention provides an orthopedic chair that is comfortable to sit on and is able to prevent spinal diseases.
  • the said orthopedic chair comprises an ergonomic seat and an ergonomic seat back.
  • the said seat is mounted on a support that can include well- known height adjustment means; the support will not be described herein as it is not included in the invention.
  • the said seat is made of non-resilient materials and has a shape that matches the natural contours of an occupant's buttocks, thighs, and upper legs.
  • the said seat has its concave backward portion connect to the concave lowest portion of the said seat back, creating a dedicated concave zone that contours the occupant's buttocks closely but comfortably.
  • In the center of the seat's concave backward portion is a small hump that contours tightly the occupant's sacrum and coccyx if his buttocks are fitting inside the dedicated concave zone.
  • the forward portion of the said seat has a wide W-shape that contours the occupant's upper legs comfortably.
  • the two concave zones of the seat's W-shaped forward portion contours the back sides of the occupant's upper legs.
  • the center zone of the seat's W-shaped forward portion is convex and has two functions. The first function is to prevent the occupant's buttocks from gliding off the seat, keeping the buttocks stay in the dedicated concave zone. The second function is to encourage the occupant to fit his buttocks inside the dedicated concave zone, as sitting on the convex center zone of the W-shaped forward portion is not comfortable.
  • the seat is designed to be inclined backwardly in such a way that, when the occupant intentionally sits on the seat's W-shaped forward portion, his buttocks, pushed by the gravity force of his body, will gradually glide backward and fit themselves into the said dedicated concave zone eventually.
  • the left side and right side of the seat's W-shaped forward portion are convex so that they contour the outer sides of the occupant's upper legs. Moreover, the convex left and right sides of the seat's forward portion keep the upper legs in a correct position, i.e. inside the two concave zones of the seat's W-shaped forward portion, since putting the legs on top of the two convex left and right sides is not comfortable.
  • the said seat back is also made of non-resilient materials and is ergonomically designed in such a way that it contours the occupant's back.
  • the seat back tilts backward to stay at an angle of 135 degrees to the seat.
  • the said seat back comprises a lowest portion, as already described above, that is concave to contour the occupant's buttocks, a middle portion that is convex to contour the lumbar vertebrae, an upper portion that is concave to contour the thoracic vertebrae, and a headrest on the top.
  • the left and right edges of the seat back are convex to keep the occupant's back from bending left or right.
  • a proper sitting posture is defined as a posture in which the occupant sits on the seat of the said chair in such a way that his buttocks fit inside the dedicated concave zone, his sacrum and coccyx are contoured tightly by the small hump in the center of the seat's concave backward portion, his two upper legs fit inside the two concave zones of the seat's W-shaped forward portion, and his back stays at an angle of 135 degrees to his upper legs and is contoured comfortably by the seat back.
  • less strain is placed on the spinal disks and associated muscles and tendons.
  • the chair help the occupant easily and comfortably maintain an angle of 135 degrees between his back and upper legs over time; in other words, the pelvis stays at an "neutral" position and the shape of the spine is close to the natural S-shape in a standing posture. Since the chair keeps an occupant in a proper sitting posture, it is capable of preventing spinal diseases.
  • the chair maintains substantially equal pressure distribution throughout the surface area of the body that is in contact with the chair, resulting that the occupant feels very comfortable sitting on the chair.
  • FIG. 1 is a perspective right-front view of a comfortable orthopedic chair for prevention of spinal disease according to the invention.
