[0049] A lifting rod 2, which is slidably adjustable in height and is mounted on the waist cushion 102;

[0050] The fastening structure 5 is used to fix the relative position between the lifting rod 2 and the waist cushion 102 .

[0051] Two fixed rod sleeves 501 are provided on the top of the waist cushion 102, and the lifting rod 2 is inserted and slidably arranged in the fixed rod sleeves 501 of the waist cushion 102. The surface of the lifting rod 2 is smoothed to reduce the friction between the lifting rod 2 and the fixed rod sleeves 501, so that the lifting rod 2 is easy to slide. A shoulder support part 3 is fixed on the lifting rod 2. The shoulder support part 3 is used for the user to lean on the shoulder and back. The main body of the shoulder support part 3 is also made of hard plastic materials such as polypropylene, and a soft cushion layer can be provided on the outside. The specific structure of the soft cushion layer is that the surface is artificial leather and the internal filling is made of Memory sponge, improve the comfort of users; regarding the fixing method of the shoulder rest 3 and the lifting rod 2, a through hole penetrating up and down can be provided on the main body of the shoulder rest 3, and the shoulder rest 3 is sleeved on the lifting rod 2, and the two are fixed by bolts and nuts passing through them, and this structure will not be observed when covered with a cushion layer, which can improve the aesthetics; a head rest 4 is provided at the top of the lifting rod 2, and the head rest 4 has a certain curvature, which can effectively support the user's head, and because the head rest 4 has a curvature, when the neck and a part of the head connected to the neck lean on the head rest 4, the head will receive resistance when it deflects to both sides, which can stabilize the user's head and prevent the head from detaching from the head rest 4.

[0052] A traction and stretching belt 9 is also provided on the shoulder rest portion 3, and the traction and stretching belt 9 is fixed to the shoulder rest portion 3 by screws and gaskets. The specific structure of the traction and stretching belt 9 adopts the structure of the traction and stretching belt 9 that can be used for back correction. The inner support adopts a silicone strip, which can be stretched in length, and the outer part is wrapped with elastic fabric, such as seamless nude fabric with good breathability or green canvas, which has both elasticity and support to ensure that it fits the back curve. In addition, mesh yarn, velvet cotton and other materials for reinforcement can be added inside the elastic fabric to improve durability and skin-friendliness. The belt body is passed around the shoulder to form a mechanical traction effect through elastic force, and the annular belt body can be disconnected in the middle. The ends of the disconnected belt body need to be fixed by a fixing clip to prevent the end fabric from opening. The fixing clip structure refers to the backpack strap, and the belt body can be adjusted in tightness through Velcro 14 or a snap button 15 to adapt to different body shapes of users. The snap button can be a one-button disconnect type, which can be more convenient to disassemble.

[0053] The functions of the ergonomic sitting posture chair are increased by arranging the shoulder support 3, the head support 4 and the traction and stretching belt 9, so that the ergonomic sitting posture chair has the function of correcting the back, which can help children and adults with sitting posture problems to correct their sitting posture and cervical spine, and the position of the shoulder support can be adjusted as the child grows up, so that the service life is longer and it is also suitable for users of different body shapes; and by adjusting the position of the traction and stretching belt, the traction and stretching belt has the function of fixing the upper body of the human body, supporting the upper body of the user through the lifting rod, reducing the pressure of the upper body on the human waist, relieving the pressure on the waist, and allowing users with waist injuries to sit for a long time without hurting their waist when needed.
