Claims

[Scope of utility model registration request]

In a seat device comprising a seat back that is tiltably supported by a reclining mechanism consisting of a base on the rear end side of the seat cushion and an arm rotatably supported by the reclining mechanism, the seat back frame of the seat back is moved upwardly and downwardly. an upper frame and a lower frame that are configured to be divided into two parts and are relatively rotatably supported by a bent shaft support; The interlocking mechanism is rotatably supported on the upper end side of the lower frame, and the lower end side of the upper frame is connected to the eccentric position of the interlocking mechanism. It has a disc and a rotation amount transmission means for transmitting heat to the rotary disc by the amount of rotation accompanying the tilting operation of the lower frame by the reclining mechanism, and rotates according to the amount of rotation transmitted by the transmission means. 1. A seat device characterized in that the relative tilting operation state of the upper frame connected to the lower frame can be adjusted by the movement of the rotating disk at its eccentric position.
