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 are constructed by dividing the frame into two parts, and are rotatably supported relative to each other by a bent shaft support; The link mechanism has an upper end rotatably connected to and supported by the upper frame, and a lower end pivotally supported by the lower end of the lower frame. A link lever that is pivotally supported at an eccentric position of a pinion gear provided at the same time selectively engages with the pinion gear as the reclining mechanism tilts the lower frame toward the base side to transmit the reclining motion. A seat device comprising: a gear portion provided on a portion of the seat cushion side.
