AI Technical Summary
Traditional seat cushions are fixed and not adjustable, which cannot adapt to the differences in body shape among users. This causes users to frequently adjust their bodies when changing positions, reducing efficiency and potentially leading to muscle strain.
A sliding seat cushion was designed. Through the mechanical transmission structure of the seat cushion and lumbar support components, the seat cushion and lumbar support can move synchronously and automatically adjust their positions to match changes in sitting posture according to user needs.
By adjusting the seat cushion and lumbar support, localized pressure concentration is avoided, the natural curvature of the spine is maintained, muscle strain is reduced, and user comfort and efficiency are improved.
