Office Chair Recline Function

The recline function of office chairs is mainly achieved by adjusting the recline tension, recline angle locking, and dynamic ergonomic following technology. The specific operations and functions are as follows:

1. Recline Tension Adjustment

The adjustment of recline tension (damping force) aims to accommodate different body weights or usage habits, preventing sudden falls due to insufficient tension during reclining or difficulty in reclining due to excessive tension.

• Adjustment Method: Controlled by a knob on the chair base. Turning it clockwise increases the rebound support force, while turning it counterclockwise decreases it. For example, users with lighter body weights can turn the knob counterclockwise to weaken the tension, making reclining easier; users with heavier body weights or those requiring stable support can turn it clockwise to strengthen the tension.
• Technical Principle: Some high-end ergonomic chairs (such as the Qingxian Pro) use pneumatic or mechanical structures. By turning the knob, the compression degree of the internal spring or gas rod is changed, thereby adjusting the resistance during reclining.

2. Recline Angle Locking

The recline angle locking function allows users to fix the inclination angle of the chair back to meet different scenario needs.

• Operation Method: Achieved through a control lever on the right side of the seat cushion. Pulling the lever backward unlocks the recline function. After adjusting to the target angle, pushing the lever forward locks it. For example, 105 degrees is suitable for sitting upright for office work, 125 degrees is suitable for relaxing during work breaks, and 160 degrees, the extreme recline angle, can be used for noon naps.
• Application Scenarios: After locking the recline angle, users can maintain a stable posture for reading, closing their eyes to rest, or taking short breaks, avoiding the impact of a wobbly chair back on the experience.

3. Dynamic Ergonomic Following Technology

Some high-end ergonomic chairs (such as the Qingxian Pro) are equipped with dynamic ergonomic following technology, enabling the chair back, armrests, and headrest to adjust synchronously with the body's reclining, enhancing comfort and support.

• Functional Advantages: When traditional office chairs recline, the waist may become suspended due to changes in the angle between the chair back and the seat cushion, increasing lumbar pressure. The dynamic following technology ensures that the waist, back, armrests, and headrest always conform to the body's curves through a linkage design, avoiding waist suspension and reducing fatigue from prolonged sitting.
• Technical Implementation: By using mechanical structures or sensors to detect the body's reclining angle, the positions of various components are adjusted in real-time. For example, when reclining, the chair back tilts backward, while the armrests move backward and upward simultaneously, and the headrest angle is also adjusted accordingly, forming continuous support.

Summary: The recline function of office chairs combines flexibility, stability, and comfort through tension adjustment, angle locking, and dynamic following technology. Users can easily adjust according to their body weight, usage scenarios, and needs using the knob on the chair base and the control lever, enjoying a personalized sitting experience.
