The most common office chairs are lift chairs and bow chairs. Many people choose bow chairs instead because of the safety hazards of pneumatic rods. However, many people worry that the bow chairs will break when they lean back. Then the editor will work with you to study the load-bearing principle of the bow chair.
When we sit on the cushion of the chair, the center of gravity falls on the center of the chair. However, due to the structure of the chair, the lower part of the center of the chair is empty and has no direct support, so gravity is supported by the arched structure on both sides or under the cushion. Some people may worry about whether the carrying capacity is sufficient when looking at the lower part of the seat. The reason why it has sufficient load-bearing capacity lies in its overall structure, which distributes the pressure on the seat to the steel frame.
When we lean back with the bow chair, the pressure on the steel frame increases. So to judge whether a bow chair is strong, you need to look at its main supporting part: whether the steel frame is strong. Office chairs on the market usually come in two types: aluminum alloy and iron chrome plated. The bow chair is generally iron chrome plated, which has stable structure, strong hardness and certain flexibility. The bending angle of the pipe has been tested repeatedly, and the bearing capacity is strong, which can fully meet the daily office needs. There is no problem with normal use for 5 to 10 years.
When buying a bow chair, you should also pay attention to the following points:
1. The wall thickness of the steel frame should not be too thin. Currently on the market, they are generally 1.5mm and 1.8mm, and the thickness is 2.0mm, but less; the others are casings, but the cost is relatively high. If the thickness is 1.2 or 1.0, the shelf is easily deformed, but office chair manufacturers generally do not use this material.
2. Pay attention to whether the connection between the steel frame and the seat cushion and backrest is firm. If the joints are not strong enough, the cushion or backrest will fall off and the chair cannot be used for a long time.
3. Choose products produced by regular manufacturers. Regular office chair manufacturers will carry out multiple gravity tests on the load-bearing capacity of the chair, and the steel pipe bending angle will be repeatedly tested and designed to ensure safety before it can be put into production. If you are petty and cheap, you may be of poor quality.
After reading this, I believe everyone knows that the weight-bearing capacity of the bow chair is very good. As long as you buy a chair made by a regular manufacturer, you don’t have to worry about safety during normal use.
