Claims

[Scope of utility model registration request]

In a seat device comprising a seat back 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 raised, An upper frame and a lower frame that are configured to be divided into two parts below and are relatively rotatably supported by a center-folded shaft support; The link mechanism includes a link mechanism that rotates relative to the seat cushion, and the link mechanism has a lower end rotatably supported on the seat cushion side and an upper end rotatably supported on the upper frame side. a link lever, and a link operation position adjusting means that can adjust the rotational fulcrum position of the link lever by engaging at an arbitrary position at the upper end or lower end of the link lever; A seat device characterized in that the relative tilting operation state of the upper frame with respect to the lower frame can be adjusted by selectively operating the means by external operation and variably adjusting the rotational position of the link.
