Document Type and Number:
WIPO Patent Application WO/2013/058538
Kind Code:
A corrective chair using a slider means according to the present invention comprises: a support leg; a seat board which is combined on said support leg, and on which a user sits; and a backrest which has a lower part combined with an upper part of said support leg, and supports the back part of the user when the user sits on said seat board, wherein a slider is interposed between said support leg and said seat board, and wherein said slider comprises: guide rails which are combined with both sides of an upper side of said support leg, and are inclined toward said backrest such that said backrest side is low and the opposite side to said backrest is high; guide blocks having lower parts which are combined on said guide rails to slide thereon, wherein the guide blocks are positioned on the opposite side to said backrest among said guide rails in an initial state and the upper parts of the guide blocks are combined to a lower side of said seat board; and elastic bodies, wherein each elastic body has one side that is combined to the lower side on the front of said seat board and the other side that is combined to the upper side of said support leg, whereby when the user sits on said seat board, said guide blocks slide in an inclined direction of said guide rails and said elastic bodies are compressed to move said seat board toward said backrest side such that the back part of the user is in contact with said backrest, and when the user stands up from said seat board, said elastic bodies are returned to the original state such that said guide blocks and said seat board come back to the original state. According to the present invention, since the guide rails are positioned in the inclined manner, the seat board moves backward toward the backrest when the user sits on the seat board whereby the back part of the user comes in contact with the backrest, thereby allowing the back portions of the upper body of the user, such as the pelvis and the waist or the like, to be straightened even though the user unconsciously sits on the chair, and thus the posture of the user can be corrected in such a manner that the user is able to work by sitting on the chair with proper posture.
