There are many different styles and designs of chair tilt mechanisms to choose from. Most of you know that tilt mechanisms can be sorted by their function. But you probably didn’t know that they can also be sorted by the number of functions they perform. That’s what we’d like to introduce to you.
The chair tilt mechanism is mounted under the seat and connected to a cylinder. This structure is very obvious. From the video we can see how to use the multifunctional tilting mechanism. However, it is invisible when a person is sitting in the seat. When people buy a chair they are in a similar situation and most people overlook this.
When choosing an office chair, the layman usually pays attention to appearance, function and price.
While experts know that the technical core of office chairs lies in the design and manufacture of the office chair tilt mechanism, the core of safety lies in the category of gas cylinders. As long as customers master these two points, they can pick out seats that are usually durable, comfortable and safe.
The following will give you an idea of the 5 general office chair tilt mechanisms on the market, with features that increase from 1 to 5.
Summary of 5 office chair tilting mechanisms
To give you a clearer picture of the tilt mechanisms with different functions, we have summarized these 5 functions and created a table to show them. Then, we will explain them in detail.
1. General Lifting Tilt Mechanism – One function
Only the control height of the seat (high and low), the seat cushion can be raised and lowered freely.
Press the button of the chair cylinder in order to release the pressure inside the cylinder.(how is the cylinder working)
It’s commonly used in bar chairs, laboratory chairs.
2. Hot sale dual function tilt mechanism – dual function
This tilting mechanism has a control lever. The seat cushion can be raised and lowered freely like the one above.
There is also a rotary control device, which can control the back elasticity by spring and thus control the manual. However, it cannot lock the angle of the back tilt.
Design features of the tilt mechanism NG003B
As shown above, our swivel tilt mechanism NG003B is designed in the shape of a butterfly.
-The butterfly-shaped tray has a top surface 2 and holes 21 for attachment to the chair’s seat pan.
-And the recessed and downward facing plate frame 4 together with other accessories form the support system A. The support system A is set with a round tube 1, lever 5 and flexible knob 6.
Seat tilt
Most office chairs with this tilt mechanism have a seat cushion directly attached to the seat back structure. Therefore, when tilting backward, the angle between the seat back and the seat cushion is fixed, the body’s sitting position will not change.
In other words, if you want to lie down for a long time while resting, the body will not be able to reach a position close to lying down. Therefore, generally speaking, consumers will move their hips slightly forward to adjust their sitting position. The effect of adjusting sitting posture by moving the body forward is limited. In addition, due to improper chiropractic force, it is easy to cause pain and soreness.
Rear tilt
There is also a structure in which the seat backrest and seat cushion are assembled separately. In this structure, L-shaped brackets are used to attach the seat backrest and are attached to the seat cushion with springs. As a result, the seat backrest has the flexibility to tilt backwards. Only the chair backrest has a flexible recline. Although the seat cushion remains motionless, this is not enough for a long reclining rest.
However, it is simple in construction and affordable. It is really cost effective, so it is in high demand.
3. Three-function tilt mechanism
This tilting mechanism is a popular tilting mechanism at present. It has three adjustment functions: backward locking, seat lifting and backward elastic adjustment.
In addition, the appearance of this tilt mechanism is very diverse, such as our NG012D, NB002, NT002C. its three functions can be achieved by one lever or two levers and a knob.
The above three different tilt mechanisms all have a KNOB to adjust the spring force when tilting.
Rotate the cylindrical knob at the bottom of the tilt mechanism clockwise to increase the elasticity of the back of the chair. And rotate it counterclockwise to decrease the elasticity of the back of the chair.
4. Ergonomic four-function tilt mechanism
Compared with the general three-function tilt mechanism, the ergonomic four-function tilt mechanism increases the front and rear adjustment of the seat cushion.
The depth adjustment function of the seat cushion makes it suitable for users with different leg lengths. The user makes the thighs sit completely on the cushion by moderate adjustment. Increasing the contact area between the body and the seat cushion is the best way to reduce the pressure on the lower extremities. Less pressure makes users feel more comfortable and sit for longer periods of time.
The cushion depth adjustment function is one of the main differences between a regular office chair and an ergonomic office chair.
There are multiple styles of four-function tilt mechanisms with ergonomic wire controls. They can be operated by buttons, levers, wheels or wire control technology.
This prevents traditional tilt mechanisms from having the controls protrude directly from the mechanism. This then leads to a scattered and unsightly placement of each control function.
5. Ergonomic five-function tilting mechanism
In addition to the initial four adjustment functions, the five-function tilt mechanism also adds a seat angle adjustment function. This can adapt to the special needs of different users from more indicators.
For example, when you need to write and read at the desk, users more easily adjust the seat cushion to slightly tilt forward. When watching movies or resting, adjust the seat cushion to tilt back and feel more comfortable.
For the four types of tilting mechanism mentioned above, the seat plate can only be tilted backwards and the backrest can be passively tilted backwards. However, the seat plate of the five-function tilt mechanism can not only tilt backward, but more importantly, it can independently tilt forward. The chair can be tilted forward to ensure even distribution of leg pressure and to keep the feet tight to the ground. Therefore, sitting in this chair, your legs will feel more comfortable.
5 Advantages of the functional tilt mechanism for the user
Allows the user to be in a comfortable position
Relieves user’s back pain
Improves blood circulation
An ergonomic computer chair with seat angle adjustment requires a close connection between the tilt mechanism and the seat cushion design.
Therefore, when it is produced in the factory, the tilt mechanism, seat cushion and seat back are usually pre-assembled.
Once the customer gets the chair, he just needs to attach the tripod to the top of the seat with a pneumatic lever, which is easy to install.
Conclusion
The different types of tilt mechanisms mentioned above are ordered by the number of functions they can perform. They can meet different levels of adjustment needs.
Before purchasing a tilt mechanism for your office chair, you should consider the “2 Whats”.
What is your budget?
What features do you need?
After that, you can find the right chair for your office chair.
