Description

Technical Field

[0001] This utility model relates to the field of lifting seat technology, and in particular to a child's posture control lifting seat. Background Technology

[0002] In today's society, with the widespread use of electronic devices and the increasing pressure of learning, the problem of poor posture among children is becoming more and more serious. Looking down at mobile phones and tablets for a long time, or hunching over while studying, these poor postures not only affect children's physical shape, leading to scoliosis, hunchback and other postural problems, but may also cause health risks such as myopia and cervical spondylosis, which pose a great threat to children's growth and development and future quality of life. A chair for use with a children's study desk, with announcement number CN222171756U, relates to the field of children's study chair technology. This utility model includes a fixed seat with a lifting device fixedly installed on its top surface. The lifting device includes an adjustable seat with a lifting rod installed inside. A positioning frame is fixedly installed at the top of the lifting rod, and a seat platform is fixedly installed on the top surface of the positioning frame. A footrest is installed on one side of the bottom surface of the seat platform. This footrest assists in supporting and placing the child's feet and legs when sitting in the chair, solving the problem that existing children's chairs cannot provide foot support, causing the child's feet to dangle, resulting in significant pressure on the thighs, poor blood circulation in the legs, and a tendency for the legs to sag, leading to a forward shift of the body's center of gravity and causing the child to slouch at the desk. This not only affects the child's physical and mental health but also their learning. The existing technology described above uses a fixed backrest angle, which is inconvenient to adjust. Children's spines are in a rapid development stage and have multiple physiological curves. A backrest that is difficult to adjust cannot adapt to children's different sitting postures and cannot provide proper support for the spine in various activity scenarios. An unsuitable backrest angle can cause children's back muscles to be in a state of tension for extended periods. Taking the posture of doing homework as an example, if the backrest angle cannot be adjusted to fit the body, the back muscles must continuously exert force to maintain balance, which can easily lead to muscle fatigue and, in the long term, muscle strain, affecting normal physical development. Therefore, corresponding improvements are needed. Utility Model Content
