Office Chair with Linked Seat
Office chairs with linked functionality can automatically adjust support areas based on human movements, providing more adaptive dynamic support. Below are introductions to two typical products:
The core linked mechanism of the Sihoo B100Pro Ergonomic Chair is embodied in its self-developed seat-back linked chassis. This chassis achieves coordinated movement between the seat cushion and the backrest during reclining through mechanical structures: when a user leans back, the seat cushion does not tilt upward due to angle changes, avoiding the issue of thigh compression seen in traditional office chairs when reclining; simultaneously, the lumbar support point on the backrest dynamically adjusts its position with the body's recline, maintaining continuous contact with the lumbar spine and preventing gaps or excessive pressure on the waist. Additionally, this chassis supports manual adjustment of recline resistance, allowing users to customize the ease of reclining based on their weight or usage habits, and enables infinite suspension with a maximum recline angle of up to 150 degrees that can be locked, meeting needs for scenarios such as lunch breaks. This linked design, through precise coordination of mechanical structures, addresses the pain points of traditional office chairs during reclining, such as "seat cushion tilting upward and lumbar misalignment," enhancing comfort during prolonged use.
The linked system of the Qingxian Dynamic Ergonomic Chair S1 focuses more on multi-area coordination. Its holographic synchronized system achieves dynamic matching between the "human body and the chair" through simultaneous linkage of 60 joints in the neck pillow, backrest, seat cushion, and armrests: when a user adjusts their sitting posture, the neck pillow adjusts its support angle to follow the head's position, the backrest's curve conforms to the natural curvature of the spine, the seat cushion slightly adjusts its tilt to distribute pressure on the buttocks, and the armrests synchronously rise or rotate to support the arms. This system supports 5-level recline adjustment, allowing users to choose different recline amplitudes based on their needs, with the linked system maintaining synchronized support across all areas during the process. This design achieves full-range dynamic support from the neck to the waist through coordinated movement of multiple joints, making it particularly suitable for users who need to frequently adjust their sitting posture or maintain different work states for extended periods.
