Description
- This application is a continuation-in-part of application No. PCT/IB2011/053859 filed on 03 Sep. 2011 with WIPO and application No. 13262636 filed on 2 Oct. 2011 with USPTO. The two applications have the same content.
- 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.
- Data from the British Chiropractic Association says that 32% of the population spends more than 10 hours a day seated. Together with the long working hour, incorrect seating postures lead to serious spinal diseases. Another research from the association shows that 51% of Brits suffer from some form of back pain. Given that, the role of correct seating positions cannot be clearer; it prevents spinal diseases and reduces back pain.
- On Nov. 28, 2006, BBC News published an article named “Sitting straight bad for backs”. In which, it featured a research done by a group of Scottish and Canadian researchers confirming that the best sitting position is leaning back, whereas the upper legs are at an angle of 135 degrees to the spine. With the 135-degree sitting posture, less strain is placed on the spinal discs and associated muscles and tendons, compared to the strain in an upright 90-degree sitting position and in a slouching position where the body bends forward. When strain is placed on the spine, the spinal discs start to move and misalign. At a 90-degree sitting position, this movement is most prominent. The discs is least moved when an occupant is sitting back at a 135-degree sitting position. Therefore, sitting at 135-degree position can prevent spinal diseases.
- Although a 135-degree chair offers the best sitting position, it actually requires a dedicated design to be comfortable to sit on. It has been found that maintaining substantially equal pressure distribution throughout the surface area of the body that is in contact with the chair results in the greater comfort.
- Many chairs that are capable of offering a 135-degree sitting posture have been invented. U.S. Pat. No. 5,630,648 describes a chair with an adjustable seat back so that an occupant can achieve a 135-degree sitting posture. However, sitting on this chair, 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 Seat™ Eco chair is another invention, in which the seat is tilted forwardly so that an occupant can obtain a 135-degree sitting posture. However, since 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. In which, 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. In which, 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.
- Furthermore, to ensure that the occupant always fit his buttocks inside the dedicated concave zone, 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.
- Here, 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. When an occupant is sitting in this proper sitting position, less strain is placed on the spinal disks and associated muscles and tendons. Given that the seat and the seat back are ergonomically designed and are made of non-resilient materials, 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.
- Moreover, as it is designed ergonomically to contour the occupant's body, 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.
