Description

Technical Field

[0001] The invention relates to the technical field of seats, and in particular to a seat armrest. Background Art

[0002] A chair is a kind of daily furniture, a kind of seat with a backrest and armrests. The structure of a chair generally includes: a support leg and a seat cushion connected to the support leg, and a backrest support connected to the seat cushion or the support leg, a backrest and a lumbar support are installed on the backrest support, and an armrest is installed on the seat cushion.

[0003] Existing armrests of seats are generally fixed on the seats, and the height of the armrests and the distance between the armrests and the seats remain unchanged. When people of different body shapes sit on the seats, since the position of the armrests remains unchanged, it is easy for obese people to feel uncomfortable when sitting on the seats.

[0004] To solve the above problems, a Chinese patent application with application number 201910465997.0 discloses a chair armrest. The chair armrest disclosed above includes an armrest located at the top and a support rod connected to the bottom of the armrest structure.

[0021] Furthermore, the support part 2 is tiltedly arranged on the lifting column 3, the panel 1 is rotatably connected to the front end of the support part 2, and the lifting column 3 is rotatably connected to the rear end of the support part 2. The lifting and lowering of the armrest is realized by the provided lifting column 3, and the two ends of the provided support part 2 are rotatably connected to the panel 1 and the lifting column 3, respectively, so that the support part 2 can rotate on the lifting column 3, the panel 1 rotates on the support part 2, and the panel 1 can be adjusted horizontally along its length direction. A control structure 5 is arranged on the side of the panel 1 for controlling the panel 1 to flip forward along the length direction of the panel 1, so as to adjust the angle of the panel 1 in the length direction, so that the front end of the panel 1 tilts up and down, thereby satisfying the support of the panel 1 for the arm. The above structure realizes the arbitrary adjustment of the armrest in five directions, meets the use needs of different users, and improves the comfort of the seat armrest.

[0022] The panel 1 includes a top plate 101, a bottom plate 102 and a connecting seat 103. The bottom plate 102 is provided with a connecting groove 1021. The connecting seat 103 is slidably connected to the connecting groove 1021. A plurality of first positioning grooves 1022 are formed in the connecting groove 1021 along the length direction of the panel 1. First positioning members 1031 matching the first positioning grooves 1022 are provided on both sides of the connecting seat 103. Further, the top plate 101 is arranged on the bottom plate 102, the connecting seat 103 is located between the top plate 101 and the bottom plate 102, the connecting groove 1021 is arranged on the upper surface of the bottom plate 102, and the connecting groove 1021 is arranged along the bottom plate 102 is arranged in the length direction, the connecting seat 103 is located in the connecting groove 1021, a plurality of first positioning grooves 1022 are arranged on the side wall of the connecting groove 1021, and the plurality of first positioning grooves 1022 are evenly distributed along the length direction of the connecting groove 1021, and the plurality of first positioning grooves 1022 are arc-shaped structures, and a spring is arranged between the first positioning member 1031 and the connecting seat 103, and the first positioning member 1031 is abutted against the first positioning groove 1022 by the elastic force of the spring, and at the same time, the abutting surface between the first positioning member 1031 and the first positioning groove 1022 is an arc-shaped structure adapted to the first positioning groove 1022. When the position of the panel 1 is to be adjusted, the panel 1 is moved simultaneously so that the connecting seat 103 moves in the connecting groove 1021, thereby causing the first positioning member 1031 to slide in the first positioning grooves 1022.
