Abstract
【Item Uses】 This design is a chair back frame installed on a chair to provide back support. 【Design Description】 The design is characterized by its overall framework consisting of two independent rectangular frames, which taper slightly at their junction to form a distinct waistline, enhancing the visual impression of functional zoning. The central support at the back of the frame extends upwards to the middle section, where it branches into two strong supporting ribs, forming a "Y" shape. At the center of the branching point, there is a prominent vertical V-shaped groove. At the same time, on the back of the support at the bottom tip of the V-shaped groove, a downward-extending recessed groove is formed, increasing visual depth, detail, and industrial aesthetics. This combination creates a design with a unique visual effect.
