Claims

[Scope of utility model registration request]

In a seat device comprising a reclining mechanism that tiltably supports a seat back on the rear end side of the seat cushion, the seat back frame of the seat back is divided into two parts, an upper part and a lower part, and the seat back frame is divided into two parts, and the seat back frame is divided into two parts, and the seat back frame is divided into two parts, and the seat back frame is divided into two parts, and the seat back frame is divided into two parts, and It comprises an upper frame and a lower frame that are rotatably supported, and an interlocking mechanism that is operated in conjunction with the tilting operation of the reclining mechanism and rotates the upper frame relative to the lower frame. The interlocking mechanism includes a first rotating member that is rotated according to the amount of rotation of the lower frame by the reclining mechanism, and a rotating member of the lower frame that receives rotational force from the first rotating member via a rotation transmission means. a second rotating member pivotally supported on the upper end side; and a second rotating member that is provided integrally with the second rotating member and engages with a portion of the upper frame to tilt the upper frame relative to the lower frame. A seat device comprising a cam member that is operated.
