It is pivotally connected to each of the tips of both legs of the foot support 6, and is installed between the both legs of the foot support 6.
' is fixed. The pivot rod 8.8' is a pair of tubular members 10.1 fixed to a support plate 9 installed between the frame 1.
The U-shaped support member 11 is slidably inserted into the U-shaped support member 11, and is pivotally supported at the tips of both legs. On the other hand, a pivot rod 12 is fixed to the back surface of the central part of the foot support 7, and a link 13 is connected between this pivot rod 12 and a pivot rod 3a fixed to the lower surface of the bottom reinforcing member 3. are pivotally connected.

の傾斜状態が保たれ、十分実用性があることが判った。In the reclining chair having the above-mentioned configuration, as is particularly clear from FIG. 4, it is possible to tilt the backrest portion 2 to the position indicated by the two-dot chain line, and in this case, the seat frame member 5.
5', the foot support 6, the support member 11 and the communication member 13 reach the position shown by the two-dot chain line. Therefore, the seated person transitions from the seated state to the supine state while remaining seated. Note that even if the tubular member 10 is not made to have a diameter that can be reduced freely, but is made into a rigid sleeve, and the stopper is omitted, the backrest portion 2
It was found that the tilted state was maintained and it was sufficiently practical.

なされるのである。Effects of the Invention As described above, in the reclining chair according to the present invention, the backrest is pivotably supported on the frame member that is stationary on the floor, and the seat is supported at a position below the pivot point of the backrest relative to the frame member. Moreover, this seat part is supported on the frame member so as to be able to move freely in the front and back direction, and the leg support is pivotally attached to the tip of the seat part, so that it changes from a vertical position to a horizontal position according to the tilting of the backrest part. Since the seat is connected by a link, when the seated person tilts the backrest while seated, the seat moves forward, and even if the backrest is tilted, the seated person's center of gravity relative to the chair hardly moves, making the chair stable. Furthermore, the rise and fall of the seat portion is linked to the tilting and rising motion of the backrest, and the backrest can be tilted and raised extremely smoothly.
