The lower end is rotatably attached to b, and the upper end is rotatably attached to the center of the side surface of the backrest 8.

Reference numeral 13 is a headrest attached to the upper end of the backrest 8 and can be moved up and down, front and back, and 14 is a footrest mounted so as to be able to move in and out of the lower surface of the seat 3, and the floor 1 is attached to the lower surface. Wheels 14 that can move forward and backward are fixed via columns 15. Then, by sliding the wheels 14 on the floor surface 1, the footrest 14 can be stored under the seat portion 3 and can be pulled out forward.

Reference numeral 17 is a handle attached to the front side of the seat portion 3, and one end of a flexible wire 18 is connected to the lower end thereof. The other end of the wire 18 is a locking means 11 for locking the expansion and contraction of the expansion / contraction means.
It is connected to a.

In the chair with a reclining device, in a normal state, the backrest 8 is in an upright state as shown by the solid line in FIG. 1, but when the user wants to recline the chair, the handle 17 is used. Wire 18 when pulled toward you
The locking means 11a is pulled via the, and the expansion / contraction means 11 is free to extend.

Therefore, if the seat 3 is slid forward while still sitting on the seat 3, the slide plate 6
Roller 6a moves in the guide 2a. In this movement, the backrest 8 is also supported by the link 12, so that the link 12 is rotated around the lower end as a fulcrum. Therefore, the attachment point of the expansion / contraction means 11 of the backrest 8 moves in the front lower direction while compressing the expansion / contraction means 11 to the contracted state.

Therefore, the backrest 8 tilts upward so that the position of the headrest 13 of the backrest 8 is lowered with little movement in the front-rear direction, and the seat 3 is moved forward. The reclining state shown by the two-dot chain line 1 is obtained.
