Description

Synchronous tilting chassis and office chair with the chassis

technical field

The invention relates to an office chair, in particular to a synchronous tilting chassis and an office chair with the chassis.

Background technique

Office chairs, in a narrow sense, refer to the back chairs that people sit on when they are sitting on the desktop. Chairs, visitor chairs, training chairs, ergonomic chairs, the backrest and seat board of general office chairs are fixed together. When adjusting the angle, adjust the angle of the bottom plate fixed under the seat board to realize the adjustment of the chair angle. , but this adjustment method can only adjust the angle of the bottom plate, and the angle of the backrest cannot be adjusted. People are prone to lumbar disc herniation and lumbar muscle strain after using it for a long time, causing physical injuries. At the same time, the bottom plate is a flat structure. It is not enough to satisfy all users, and it is prone to deformation. Later, an office chair that can adjust the angle of the bottom plate and the angle of the backrest appeared on the market, which is convenient for people to use, but this kind of chair is basically controlled by wire. That is, the locking pin is pulled by the steel wire, and it contacts the locked state when pulled out. When it is not pulled, it automatically resets under the action of the spring to maintain the locked state. When people need to adjust, they need to bend down, causing inconvenience in use. If the office If the space is small, it is even more difficult to adjust.
