The backrest 2 includes a lower bar 21 and an upper bar 25, and the center of the lower bar 21 and the upper bar 25 are both arc-shaped, which improves the comfort of the human body. The shapes of the lower bar 21 and the upper bar 25 meet the requirements of the human body and are provided with multiple arc segments accordingly. The specific structure is in 2 shown. A second shaping bar 22 and a second connecting bar 24 are fixedly connected between the lower bar 21 and the upper bar 25 . The lower bar 21, the upper bar 25 and the second connecting bar 24 are the main support structure for the backrest 2 formed. The side wall of the lower rod 21 is fixedly connected to a second fastening eyelet 23, the second fastening eyelet 23 serving to fasten the backrest 2.

One end of the U-shaped bar 11 is rotatably connected to one end of the lower bar 21, and the other end of the U-shaped bar 11 is fixedly connected to one end of the upper bar 25 to prevent the pivotal connection of the armrest 1 and the backrest 2 to realize.

The armrest 1 and the backrest 2 are covered with a wrapping cloth, and a filling material is placed inside the wrapping cloth. In the 1-3 The illustrated structure of the armrest 1 and the backrest 2 is a skeleton, and the wrapping structure is not shown, so it is necessary to wrap the wrapping cloth outside. The filling material is used to improve seating comfort, and its material can be silk wool, grain husk, sponge and other materials. The purpose of the first shaping bar 13 and the second shaping bar 22 is to fix the filling material more conveniently while avoiding voids on the armrest 1 and the backrest 2 when leaning, which affects their performance and aesthetics.

Functional principle: During the transfer, the armrest 1 can be rotated to the backrest 2, i.e. the armrest 1 is transferred from the vertical position relative to the backrest 2 to the horizontal position. This makes the shape of the armrest 1 and the backrest 2 more uniform, so that with the same carrying space, the number of carrying ways can be increased and the transportation cost can be reduced.

Second embodiment:

In the 4-7 1 is shown a chair including a chair armrest connector according to the first embodiment. The lower part of the armrest 1 and the backrest 2 are firmly connected to a seat plate 5. The seat panel 5 comprises a back panel 51 and a front panel 52, the back panel 51 and the front panel 52 being rotatably connected to each other. The armrest 1 and the backrest 2 were equipped with the seat plate 5. Also, when the front panel 52 is rotated, the front panel can be placed vertically without affecting the rotating and constricting function of the armrest 1, which is also convenient for transportation needs. The back plate 51 and the second attachment eyelet 23 are firmly connected. The second fastening eyelet 23 has the same structure as the first fastening eyelet 12 and is rounded provided with rectangular holes. Screws can be passed through the rounded rectangular hole and screwed to the back plate 51 , so that the back plate 51 and the backrest 2 are firmly connected by the second fastening eyelet 23 .
