PURPOSE: A supporting structure for a chair for feeling virtual reality is provided to install a link between supports, thereby maintaining a distance between the supports and improving a fixing force when a chair moves. CONSTITUTION: A supporting structure for a chair for feeling virtual reality includes a chair(100), multiple supports(130), a screw shaft(151), an actuating motor(150), a base(190), a rotary shaft(196), and a connecting link(140). The chair has a seat on which a user sits, and a backrest for supporting the upper body of the user. The supports are rotatably installed on both sides and the rear center of the seat through connecting pins. The screw shafts are respectively coupled to the end portions of the supports with screws. The motors are respectively connected to the end portions of the screw shafts in order to rotate the screw shafts, and are installed inside motor brackets. The motor brackets are installed at the base, and a through-hole is formed on the center of the base. The rotary shaft is installed at the lower side of the base. The connecting link is rotatably installed in between extended bars based on a first rotary hinge and a second rotary hinge, and the extended bars are respectively extended from the end portions of the supports and the motor brackets. |
