Office Chair Deflation

If an office chair deflates, stop using it immediately and investigate the cause. It may involve aging of the seals, damage to the airbag, or failure of the gas rod. Depending on the specific type, choose to replace the seals, gas rod, or make temporary repairs. Pay attention to protection during repairs and prioritize contacting professionals.

Dangers

A leaking gas rod can cause a sudden drop in support force, leading the chair to tilt or wobble unexpectedly, increasing the risk of the user falling. If the internal structure is severely damaged, the gas rod may completely fail, causing the chair to collapse and resulting in serious injuries such as fractures. Additionally, when the chair is unstable, the user adjusting their posture may cause muscle strains, joint dislocations, or secondary injuries from colliding with surrounding objects.

Common Causes

1. Aging or damage to the gas rod seals: After long-term use, the seals at the bottom of the gas rod may leak due to wear, aging, or deformation.
2. Cracking or seal failure of the airbag rubber: Applicable to airbag-type office chairs, aging, cracking, or loose seams in the rubber material can lead to gas leakage.
3. Air pump failure: Damage to the internal air pump of the gas rod, which cannot maintain pressure, requires a complete replacement.

Repair Methods

1. Replace the seals:
   • Locate the seals at the bottom of the gas rod, disassemble them, clean the surface, and check for cracks or deformation.
   • If damaged, purchase new seals of the appropriate model and ensure they fit tightly against the gas rod during installation to prevent air leakage.
2. Replace the entire gas rod:
   • Invert the chair and use tools to disassemble the connecting screws between the gas rod and the seat base.
   • Remove the old gas rod, install a new one that fits, and ensure a secure connection before testing the support stability.
3. Replace the air pump (for gas rod types):
   • Disassemble the chair and release all the gas from the gas rod (be aware of the risk of airflow impact and recommend wearing goggles and gloves).
   • Reassemble after replacing the air pump. This operation is recommended to be performed by professionals.
4. Temporary repair (for airbag seats):
   • If there are small cracks in the airbag, use a special repair adhesive for temporary treatment, but large-scale damage requires direct replacement with a new airbag.

Self-Inspection Suggestions

1. Visual inspection: Check the surface of the airbag for cracks, bulges, or loose seams.
2. Soap water test: Apply soap water to suspicious areas. If bubbles appear, it indicates air leakage at that location.
3. Pressure drop test: Inflate and let it sit for a while, then observe the rate of pressure drop to judge the severity of the air leakage.

Precautions

• When performing repairs involving deflation, wear protective gear (such as goggles and gloves) to avoid injury from airflow impact.
• Regular maintenance (such as checking gas tube connections and replacing aging seals) can extend the lifespan of the office chair and reduce the risk of failure.
