Claims

[Scope of utility model registration request]

In a seat device comprising a seat bag 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 bag frame of the seat bag is placed above the seat bag; An upper frame and a lower frame are configured to be divided into two parts at the bottom and are relatively rotatably supported by a bent shaft support; and a link mechanism that rotates relative to the reclining mechanism, and the link mechanism includes a first link that is pivotally supported to be swingable about the rotation shaft support of the reclining mechanism, and a first link that is pivotably supported on the rotation shaft support of the reclining mechanism, and a second link that is swingably supported on the center-bent shaft support and to which the upper frame is fixed to one end;
The upper end of the link is pivotally supported on the other end side of the link, and is attached along the lower frame, and the lower end side is connected to the first link.
A third link is pivotally supported on the swinging end of the link, and a guide pin is provided protruding from the lower end of the third link, and when the guide pin is engaged, the link mechanism is activated. a guide bracket having a guide groove that is operated in accordance with the tilting movement of the reclining mechanism to rotationally displace the upper frame relative to the lower frame; and the guide pin that is engaged in the guide groove of the guide bracket. and a sub-bracket having a locking groove that prevents displacement of the guide groove in the longitudinal direction, are arranged in parallel on the base and arm sides respectively so as to overlap each other around the rotation shaft support. A seat device featuring:
