AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The utility model relates to the technical field of seat, specifically disclose translatable slide cushion, including seat base and backrest pad, still include: cushion translation subassembly and waist pad translation subassembly, cushion translation subassembly sets up at the top of seat base, backrest pad sets up at one side of cushion translation subassembly, waist pad translation subassembly sets up at one side of backrest pad, cushion translation subassembly includes cushion body, waist pad translation subassembly includes waist pad body, and the cushion body shifts position according to user demand, and the waist pad body follows the cushion body and shifts, the shift of cushion body can adjust hip stress area, avoid local pressure concentration, the dynamic support of waist pad body helps maintain the natural curvature of spine, when the cushion body shifts, the waist pad body automatically follows the shift through mechanical transmission structure, ensure that the waist support always matches the change of sitting posture, avoid the muscle strain caused by the waist suspension or excessive compression.
