Definitions

  • the present invention relates to a chair, and more particularly to a chair plate for maintaining a correct posture, to thereby make a user maintain a correct posture of the muscles and bones of the human body and prevent ill effects due to an incorrect posture.
  • a chair In general, a chair is formed of a chair plate supporting the hip and femoral region of a user, and a back support which is formed in the rear side of the chair plate to support the back of the user.
  • the chair plate is a basic element for maintaining a user's correct posture. When a user relies his or her weight completely on a chair, the user's weight is directly transferred to the chair plate.
  • the chair plate supports the hipbone and gives a direct influence on the human body in order to maintain a balance of the human body.
  • a general chair having a plane chair plate is not appropriate to make a user maintain a balance of the hipbone for a long time, to thus cause the user to easily feel fatigue.
  • the hipbone and spine may be easily twisted or bent to thus suppress a smooth function of the human body and harm the health thereof. Accordingly, a business productivity is reduced for business workers and a studying efficiency is lowered for students .
  • a chair having a chair plate which can support the hip and thigh softly are being used in order to achieve the physical health of users, in which the inner portion of the chair plate where the hip is supported is lowered more concavely than the front portion of the chair plate, and the front portion thereof is formed of a round curved surface.
  • Such a chair having a curved concave portion has the following demerits.
  • a conventional chair plate 100 is formed of a rectangular plate. Accordingly, a concave portion for supporting the hip presses the rear muscles of the femoral region at the front portions 101 and 102 of the chair plate. Such a pressure presses the muscles of the femoral region when a user sits on the chair to thus cause the user to feel comfortable for a little while, but to prevent the circulation of the blood of the femoral region and feel fatigue as time lapses.
  • the spine plays a role of maintaining a balance and a correct posture of the human body.
  • a variety of nervous systems are formed along the spinal line.
  • the various nervous systems formed along the spinal line are suppressed to thereby cause various diseases or deform the original shape, and to thus lose or reduce the original function. Accordingly, the vital life is hindered.
  • an object of the present invention to provide a chair plate for maintaining a correct posture in which the spine is maintained at a correct posture, to thereby make the muscles of the hip and the thigh comfortable and solve any inconveniences due to abnormalities of the spine which can happen during use of the chair and thus maintain a comfortable and correct posture.
  • a chair plate for making a user maintain a correct posture characterized in that the front lateral portions of the chair plate are gradually narrowly formed so that the central portion of the chair plate where the hip is loaded contacts the inner portion of the femoral region, wherein a protrusion is formed to be connected to a curved surface toward the front lateral portions of the chair plate from the central portion thereof, and the curved surface is successively sloped from the upper surface of the central portion of the chair plate toward the lateral portions thereof.
  • the protrusion formed in front of the chair plate prevents the pelvic region from protruding forward from the chair and makes the pelvic region naturally situated at the rear portion of the chair and the spine to closely contact the back of the chair, to thus reduce a burden to the spine.
  • the existing chair has no means of preventing the pelvic region from being inclined toward the front portion of the chair to thereby limit keeping a correct posture, but the protrusion applied in the chair plate of the present invention can prevent a phenomenon that the posture of the user is unintentionally ill-shaped from occurring.
  • the chair plate according to the present invention emerges from the conventional rectangular chair plate and is gradually narrowly formed toward the front portion of the chair plate.
  • the lateral surfaces at both sides of the chair plate are cut and removed.
  • Such a structure can solve a problem that the rectangular shape of the front portion of the chair plate in the existing chair suppresses the femoral region and the lower part of the body from moving outwards, to thereby interrupt free activities.
  • the chair to which the chair plate according to the present invention is applied does not suppress the femoral region and thus increases a scope of flexibility in the lower part of the body.
  • the lateral surface of the chair plate is formed with a curved surface from the upper surface thereof and thus provides the following merits in addition to the increase in the flexibility of the lower part of the body.
  • the existing chair has identical forming curves in the side or central portions, and thus presses the muscles in the fleshy inside of the thigh, to thereby prevent freedom of the lower part of the body. Also, in the existing chair, forming angles linked from the spine to the fleshy inside of the thigh or from the fleshy inside of the thigh to the calf of the leg are very sharp, to thus prevent a smooth flow in the blood circulation.
  • the lateral portions of the chair plate is gradually narrowed by curved surfaces as it goes to the front portion of the chair plate, to thereby make an angle of the human body linked from the spin to the fleshy inside of the thigh or from the fleshy inside of the thigh to the calf of the leg, to thus make the smooth blood circulation.

  • a protrusion 5 higher than the central portion 2 of the chair plate is formed in the leading end portion formed of the front lateral portions 4 and 4A of the chair plate. That is, the protrusion 5 is formed to be connected to a curved surface toward the front lateral portions 4 and 4A of the chair plate from the central portion 2 thereof, and the curved surface is successively sloped from the upper surface of the central portion 2 of the chair plate toward the lateral portions 3, 3A, 4, and 4A thereof.
  • the chair plate 1 according to the present invention is not formed of a rectangular shape forming a general chair plate, but is gradually narrowed toward the front portion distant by distances SI and S2 from the rear portion of the chair plate, and the protrusion 5 is formed at the inner position distant by distances Fl and F2 from the lateral edges of the chair plate.

  • FIG. 8 is a cross-sectional view of the chair plate cut along a line D-D of FIG. 3. As shown in FIG. 8, the leading end portion of the protrusion 5 is formed of a slow-moving curved surface in comparison with the upper portion thereof.
  • the chair plate according to the present invention emerges from various side effects occurring from the existing chair and provides an effect of giving a smooth blood circulation between the upper and lower parts of the body and increasing a freedom of the lower part of the body, by making a user maintain a correct posture. Accordingly, the present invention can prevent variation in shape and various diseases, by forming and maintaining a correct spinal line.
  • the chair plate according to the present invention is fabricated according to an ergonomic design conforming to the muscles and bones of the human body, which maintains a correct posture of the spine and the pelvic region to thereby prevent a spinal disease or incorrect posture.
