Reclining of Old-Style Office Chairs

The adjustment methods and troubleshooting approaches for the reclining function of old-style office chairs are as follows:

The adjustment methods for the reclining function of old-style office chairs are usually related to the specific design of the chair. Common types include lever-type, knob-type, and pull-rod-type adjustments. Some faults can be resolved by adjusting the locking mechanism or replacing parts.

I. Reclining Adjustment Methods

1. Lever-Type Adjustment Some old-style or simple office chairs use a lever as the unlocking device, usually located beneath the seat near the back legs. To use, pull the lever to unlock the reclining function, adjust to the desired angle, and then return the lever to its original position to lock it. This method is simple to operate, but note that the position of the lever may vary slightly depending on the chair's design.
2. Knob-Type Adjustment The adjustment knob on some old-style office chairs is located on the right side beneath the seat, circular or oval in shape. Turn the knob counterclockwise to unlock the reclining angle, adjust the angle, and then turn it clockwise to tighten and fix it. With this method, pay attention to the direction of rotation to avoid adjustment failure due to reverse operation.
3. Pull-Rod-Type Adjustment Although pull-rod-type adjustments are more commonly found in gaming chairs or high-end ergonomic chairs, some old-style office chairs may also adopt this method. The pull rod is usually located on the left or right side beneath the seat and is made of plastic. Pull the rod upward to unlock the reclining lock, adjust the angle, and then release the rod to complete the locking. This method is intuitive to operate, but ensure that the pull rod is fully returned to its original position.

II. Troubleshooting for Reclining Function

1. Reclining Won't Lock If the chair's reclining angle cannot be fixed, the locking mechanism may be loose or damaged. Try the following methods:
   • Adjust the Right-Side Handle: Some chairs have a handle on the right side. Push it in to the left to lock the reclining, and pull it out to the right to unlock it.
   • Adjust the Base Knob: Check the cylindrical knob on the base. Turn it clockwise to increase the rebound support force, and turn it counterclockwise to decrease the support force, thereby adjusting the stability of the reclining.
2. Damaged Adjustment Device If the button does not rebound after being pressed, the handle does not rotate smoothly, or the pull rod is broken, the internal parts of the adjustment device may be worn or stuck. In this case, repair or replace the adjustment device with a new one, such as replacing damaged knobs, handles, or pull-rod components. It is recommended to contact a professional repair technician or purchase compatible parts according to the chair's model for replacement.

III. Precautions Before adjusting, ensure that the chair is in a stable state to avoid tipping over due to improper operation. If the chair still does not function normally after adjustment, it is recommended to stop using it and contact after-sales service or a professional repair technician to avoid further damage caused by self-disassembly.
