Detailed ways

The embodiments of the present invention will be described below by specific specific embodiments. Those who are familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are of the present invention. Some examples, but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The utility model provides a multi-segment locking chassis office chair, which includes a headrest assembly 1, a seat back assembly 2, a seat 3 and a multi-segment locking chassis 4. The upper end of the multi-segment locking chassis 4 is movably provided with a seat 3, thereby The seat 3 can be freely rotated on the multi-segment locking chassis 4. When a person needs to turn around, the waist of the human body can rotate with the whole body, thereby avoiding the twisting of the waist and improving the comfort of the body. The multi-segment locking chassis 4 in this application adopts the structure in the prior art, and has functions such as wire-controlled synchronous tilting, adjustable seat cushion height and seat depth, back reclining, seat-side reclining elastic adjustment, etc. The specific structure is not repeated here. The rear end of the seat 3 is hinged with the seat back assembly 2, so that the seat back assembly 2 can be rotated forward or backward, and then people can adjust the angle of the seat back assembly 2 according to their own habits. To further improve the comfort of the human body during office work, the rear side of the seat back assembly 2 is hinged with the headrest assembly 1 .

According to a specific embodiment provided by the present invention, the seat 3 includes a base 31 and a vibration motor 32, and a vibration motor 32 is fixedly installed at the top of the base 31. When the vibration motor 32 is turned on, it can massage the human body's buttocks. Thereby, the fatigue of the human body is relieved. The upper end surface of the base 31 is set as an arc-shaped curved surface. When the human body sits on the base 31, the arc-shaped curved surface can increase the contact area between the base 31 and the human body and the buttocks, thereby making the human body gravity. The dispersion is more uniform, thereby improving the comfort of the human body sitting on the office chair. The bottom end of the base 31 is movably inserted with a multi-segment locking chassis 4 , and the rear end of the base 31 is hinged with the seat back assembly 2 through a torsion spring. When the human body leans against the backrest 21, the backrest 2 plays a role in reducing the impact of the human body through the torsion spring, thereby not only improving the comfort of the human body, but also improving the durability of the multi-stage locking chassis office chair.

According to a specific embodiment provided by the present invention, the seat back assembly 2 includes a backrest 21 and a massager 22, and the rear end of the base 31 is hinged to the backrest 21 through a torsion spring, thereby buffering the force of the human body. The comfort of the human body is improved, and the durability of the multi-segment locking chassis office chair is also improved. A massager 22 is fixed in the middle of the backrest 21 . The massager 22 can act simultaneously with the vibration motor 32 to massage the waist and buttocks of the human body, promote blood circulation and reduce fatigue. The upper end of the backrest 21 is hinged with the headrest assembly 1 through a torsion spring. The headrest assembly 1 mainly plays the role of protecting the neck and reducing the load on the neck.

According to a specific embodiment provided by the present invention, the headrest assembly 1 includes a pillow 11 and a support rod 12, one end of the support rod 12 is hinged with the backrest 21 through a torsion spring, and the other end of the support rod 12 is connected with the pillow 11 is fixedly connected, when the head of the human body leans on the pillow 11, the torsion spring can play a buffering role, thereby improving the comfort of the human body.

According to a specific embodiment provided by the present invention, the material of the pillow 11 is latex. The oak protein in latex can inhibit the latent bacteria and allergens, meet the requirements of environmental protection, can inhibit the breeding of bacteria and mites, and has no static electricity, emits a natural frankincense, and helps improve asthma, allergic rhinitis and other respiratory system symptoms.

The use process of the embodiment of the present utility model is as follows:

To sum up, the multi-segment locking chassis office chair proposed by the present utility model can effectively relieve human fatigue by installing the vibration motor 32 and the massager 22. The large contact area between the office chair and the human body improves the comfort of the human body.

At the same time, in view of the deficiencies and defects of the prior art, this product is connected by the backrest 21 of the chair frame and the seat cushion. Armrests are arranged on both sides of the seat cushion. High, effectively improve the shock absorption performance. The bottom is equipped with pulleys, and the shape of the backrest 21 is an S shape that fits the curve of the human spine. The user's spine can be more completely fitted on the backrest when in use; the ventilation holes of the mesh back can dissipate the sweat of the user's waist, the height of the armrest is ergonomic, and the hands are more comfortable when placed on the armrest; The angle of seat inclination and back inclination is appropriate.

The utility model has firm structure and good durability, and solves the problem of office fatigue caused by unreasonable seat design in the prior art.
