Description

TECHNICAL FIELD

[0001] The utility model relates to the field of chair, especially a handrail and seat. BACKGROUND

[0002] As a common seat in people's daily life, the structure design and assembly process of the seat have an important influence on the use experience. Generally speaking, the seat is mainly composed of four key parts: chair legs, chair cushions, armrests and backrests. The chair legs, which can be called the "foundation" of the seat, bear the heavy responsibility of supporting the weight of the entire chair. They are usually divided into front legs and rear legs, which work together to provide stable support at different positions, ensuring that the seat can maintain a balanced state in various use scenarios and not easily tip over, providing a safe and reliable sitting experience for the user.

[0003] The chair cushion is in direct contact with the human body, and its material and thickness determine the comfort of the sitting experience. A high-quality chair cushion can effectively distribute body weight and reduce the discomfort caused by long-term sitting. The design of the backrest is also related to ergonomics. It fits the human spine curve, providing the right support for the waist and back, relieving sitting fatigue, and allowing the user to maintain a relatively relaxed state even in a sitting position for a long time.

[0004] In the assembly process of the seat, the armrest plays a key role in connecting the chair legs and the backrest. It not only reinforces the overall frame of the seat in structure, but also provides support for the user's arms in function, making it easy for people to maintain a comfortable hand posture when resting, reading or using electronic devices. However, during actual installation, the assembly between the front legs and the rear legs often encounters some headaches. Due to manufacturing precision, installation environment and other factors, there may be a small deviation between the front legs and the rear legs. Although this deviation may seem insignificant, it can have a significant impact on the installation of the armrest. Specifically, the armrest may not be able to accurately align the installation slot on the chair legs, making it difficult to install the armrest in place, causing great inconvenience to the installation work and affecting the overall assembly efficiency and quality of the seat. Even potentially causing potential problems such as loose seat structure during subsequent use, reducing the service life and safety of the seat. SUMMARY
