Aurora Office Chair Structure
The structural design of the Aurora office chair centers on ergonomics, utilizing adjustable components in multiple areas to accommodate different body types and sitting postures. The main structures include the backrest, lumbar support, headrest, armrests, seat depth, and recline system. The following provides an in-depth explanation of key structures and their adjustment functions:
Backrest and Lumbar Support: The Core of Dynamic Support
The backrest is the primary structure supporting the spine in an office chair, typically designed with an S-shaped curve to fit the natural curvature of the human spine. For example, the backrest of the A20 ergonomic chair can adjust its angle in sync with the recline motion, preventing the waist from hanging unsupported. The A10 ergonomic chair is equipped with a six-position adjustable lumbar support, allowing users to move the lumbar support forward or backward according to their body type to precisely support the third to fifth lumbar vertebrae, alleviating prolonged sitting pressure. The rotational or forward-backward adjustment function of the lumbar support (such as the rotating lumbar support of the A20) can further adapt to different sitting postures, such as leaning forward for work or reclining for rest.
Headrest: Flexible Adjustment for Neck Support
The headrest adjusts in height and angle to accommodate users of different heights. Taking the A50 office chair as an example, its headrest has a vertical adjustment range of up to 130mm, covering a height range from 1.5 meters to 1.9 meters. The 15ยฐ tilt design allows users to adjust the headrest's inclination according to the recline angle, preventing excessive neck extension or compression. The lifting headrest of the A20 ergonomic chair achieves stepless adjustment through a pneumatic rod, offering convenient operation and high stability.
Armrests: 3D/4D Adjustment for Upper Limb Support
The function of the armrests directly affects the comfort of the shoulders, neck, and arms. The A20 ergonomic chair features 3D armrests that support vertical (height), forward-backward (depth), and left-right (width) adjustments to accommodate different desk heights and operating habits. Some premium models (such as the Airsys office chair) are upgraded to 4D armrests, adding a rotational function to facilitate users in adjusting the armrest angle to support the naturalไธๅ of the arms or typing postures, reducing shoulder muscle tension.
Seat Depth and Recline: Collaborative Support for Legs and the Entire Body
Seat depth adjustment accommodates users with different leg lengths by moving the seat cushion forward or backward. The seat depth of the A20 and Airsys office chairs can be adjusted up to 50mm, ensuring that users maintain a 2-3 finger gap between their thighs and the front edge of the seat cushion when sitting upright, preventing impaired leg blood circulation. The recline system achieves resistance adjustment for reclining through the chassis mechanism (such as the A20 supporting four-position recline locking), combined with a synchronous gliding function (the backrest and seat cushion angles are linked), allowing the body to maintain a natural center of gravity during reclining and reducing waist pressure.
Summary
Through modular adjustable design, the Aurora office chair translates ergonomic principles into specific functions: precise positioning of the lumbar support, flexible adaptation of the headrest, multi-dimensional support of the armrests, and collaborative adjustment of the seat depth and recline, jointly constructing a dynamic support system covering the entire body. This design not only enhances comfort during prolonged sitting but also reduces muscle fatigue risk by dispersing pressure points, meeting the needs of multiple scenarios such as office work, meetings, and rest.
