Description

Technical Field

[0001] The present application relates to the technical field of furniture design and ergonomics, and in particular to a fishbone-shaped backrest adapted to the waist structure. Background Art

[0002] Most backrest designs currently on the market use a fixed shape that doesn't adapt well to the individual body curves of users, particularly in the lumbar region. This can lead to fatigue and even lumbar spine problems after prolonged use. To enhance the user experience, some high-end chairs are beginning to incorporate multi-position adjustment designs, but these are often costly and complex. With increasing health awareness, the question of how to improve the comfort and support of seating while maintaining cost-effectiveness has become a key issue within the industry.

[0003] Existing fixed-shape backrests fail to effectively support the lumbar region, easily leading to fatigue and discomfort. While multi-stage airbag or spring adjustment methods improve comfort, they are complex, difficult to maintain, and costly. While electric adjustment mechanisms offer a personalized experience, they are expensive and unsuitable for the mass market. Therefore, existing technologies face significant limitations in balancing cost and performance. Utility Model Content
