Office Chair with Rocking Function

The 'rocking' function of an office chair is a dynamic relaxation feature achieved through a chassis linkage structure, allowing the backrest to recline within an approximate range of 35° while accompanied by slight rocking. The core purpose is to provide dynamic support and mild relaxation, rather than full reclining.

Function Definition and Core Purpose

The 'rocking' function utilizes a chassis spring-damping system and a rotating shaft linkage to enable the seat and backrest to recline synchronously, creating a dynamic support with slight rocking within a set angle range of 15°–35°. Its original design intent is to break the rigid posture during prolonged sitting, promoting blood circulation and relieving muscle fatigue through slight rocking, rather than replacing the full reclining function of traditional lounge chairs. For example, the separated floating lumbar support of the Gedeli G22 ergonomic rocking chair 001003 can conform to the lumbar curve, working in tandem with the rocking function to provide dynamic support.

Working Mechanism and Structural Features

This function relies on a chassis spring-damping system and a rotating shaft linkage structure:

1. Dynamic Linkage: When the user leans back, the backrest and seat recline synchronously, avoiding the issue of 'the backrest reclining alone causing the waist to hang in the air' common in traditional office chairs, ensuring continuous support for the waist.
2. Angle Limitation: The reclining angle is typically limited to within 35° (e.g., 15°–35°), preventing excessive reclining that could affect stability, while controlling the rocking amplitude through the spring-damping system to avoid violent shaking.
3. Adaptive Adjustment: Some computer chairs' rocking modes support custom angle adjustment, allowing users to modify the reclining amplitude according to their needs, further optimizing comfort.

Applicable Scenarios and Limitations

The 'rocking' function is suitable for scenarios requiring short-term relaxation or mild reclining needs, such as brief rests, reading, or light office work. However, due to its angle limitations and dynamic support characteristics, it cannot replace the deep rest function of lounge chairs. Additionally, this function places high demands on the chassis structure, requiring durability of the spring-damping system to prevent a decrease in support force or abnormal noises after prolonged use.
