The present invention relates to an electric chair used in a hair shop, a skin beauty shop, a dental clinic, or the like. The electric chair comprises: a base; a driving means; a first rotation arm stand; a second rotation arm stand; a third rotation arm stand; a back frame; and a leg support frame. The driving means is installed on the base with a slope and allows a rod to be moved frontwards and backwards with the supply of power. The first rotation arm stand has a central part connected to upper parts of vertical frames in both sides of the base to be rotated through a first pin and turns within the vertical frames with respect to the first pin with an operation of the driving means. The second arm stand is connected to the front side of the first rotation arm stand to be rotated around a third pin and has an upper part integrally fixated to a lower surface of a sheet frame. The third rotation arm stand rotates the second rotation arm stand around the third pin with respect to the first rotation arm stand to allow the sheet frame to move up and down. The back frame turns around a seventh pin with respect to the sheet frame while a vertical stand moves up and down when the driving means is operated in a rear side of the sheet frame, thereby changing the angle of the back. The leg support frame has a pair of leg links rotatably connected to a lower center of the back frame through an eighth pin on both sides of the sheet frame. When the leg links move a lower bracket frontwards and backwards, the upper bracket turns around a tenth pin to change the angle of the leg support. The driving means is operated to elevate the seat and change the angle of the back or the leg support. |
