Description

Ergonomic seat

Technical Field

The utility model relates to the field of seats, in particular to an ergonomic seat.

Background

After sitting for a long time, cervical vertebra and lumbar vertebra are injured to a certain extent, and as more and more people attach importance to the body health of the people, various furniture is utilized to protect the body health of the people, wherein the ergonomic chair is loved by a plurality of users, and the ergonomic chair is also a non-exclusive choice for learning and working of a plurality of people; most people can choose an ergonomic chair with a chair back separated from a chair seat, such as an ergonomic office chair shown in a patent CN202211019171.X, and the ergonomic chair can be randomly adjusted and matched with the shape of each part of a human body, so that good use experience is brought to a user, but the chair is split, has more parts, is complex to assemble, has generally heavier weight and is difficult to reduce; therefore, in the occasion of bias flow, people can select an ergonomic chair as shown in CN202121590554.3, the thickness of the chair back and the chair seat is greatly reduced, the number of parts is reduced, the weight and the assembly difficulty of the chair are greatly reduced, the application range is wider, but the chair only barely meets the ergonomic requirement, cannot exert better effects on the aspects of waist wrapping of the chair back and the protection of the spine, and still cannot meet the requirements of users on health and comfort.

Therefore, an ergonomic chair is needed, which has lighter weight, fewer parts and assembly difficulty, and reduces the overall weight, meets the requirements of ergonomics, and has better protection effect on the waist and the spine of a user.

Disclosure of Invention

In order to solve the technical problems, the utility model aims to provide an ergonomic chair, which reduces the number of parts and the overall weight by integrally forming a chair back skeleton plate and a chair seat skeleton plate, and forms two backrest support plates capable of generating elasticity on the chair back skeleton plate through hollowed-out spinal decompression grooves so as to enable the chair back support plates to accord with the ergonomics and meet the requirements of health, comfort and portability.

The technical scheme of the utility model is realized as follows:

the utility model provides an ergonomic thing to sit on, includes integrated into one piece's back bone frame plate and seat support bone frame plate, the vertical backbone pressure release groove that is equipped with the fretwork in intermediate position of back bone frame plate, backbone pressure release groove and back bone frame plate upper end intercommunication, back bone frame plate uses backbone pressure release groove as the world, two piece back backup pads that divide into bilateral symmetry setting, the back backup pad produce corresponding elasticity change when receiving leaning on the power to reset to initial condition when leaning on the power disappearance or reduction. The backbone decompression groove provides a relaxation space for the backbone of a user, and avoids abrasion caused by long-time extrusion of the backbone and the chair seat.

Preferably, the backrest support plate is a backrest end at one side close to the spine decompression slot and is a waist wrapping end at one side far away from the spine decompression slot; when the backrest receives forward and backward force, the backrest end moves backward to drive the waist wrapping end to swing inwards, so that the waist wrapping effect is formed. The waist wrapping effect of the backrest is achieved through the simple structure, and more comfortable seat experience is provided for a user.

Preferably, the chair back framework plate is divided into a connecting part and a backrest part from bottom to top, the backrest part is formed by two backrest support plates together, the connecting part is used for connecting the chair seat framework plate, and the length of the spine pressure relief groove is two-thirds to three-quarters of the height of the backrest part. This length is sufficient to allow the spine to relax and not so much as to allow the connecting structure of the two back support plates to be too loose, enhancing structural stability.

Preferably, the section between the lower end of the spinal decompression groove and the lower end of the backrest part is a thickened root base part, and the backrest part is gradually thinned from the root base part. The thickness design of the thickened root base and the backrest part enables the chair back bone plate to swing and prevents excessive swinging.

Preferably, the front surface of the backrest supporting plate is fixed with a backrest sponge, the surface of the backrest sponge is concaved inwards to form a backrest ventilation groove, each backrest supporting plate is divided into three areas by the backrest ventilation groove in the left-right direction, the three areas are shoulder bone supporting areas in the middle from inside to outside, shoulder bone supporting areas in the outer ring of the shoulder bone supporting areas, shoulder bone peripheral muscle supporting areas and back side supporting areas. The soft sponge can give the back comfortable back and lean on the experience after the subregion, and the by back air groove prevents that the sponge from being stuffed for a long time and the back can not breathe freely.

Preferably, the surface of the seat frame plate is fixedly provided with a seat sponge, the surface of the seat sponge is concaved inwards to form a hip ventilation groove, the hip ventilation groove divides the seat frame plate into three areas along the radial direction from the center to the outer ring, the three areas are respectively a central middle supporting area from inside to outside, a hip supporting area at the periphery of the middle supporting area and a thigh supporting area at the outermost periphery. Soft sponge can give buttock comparatively comfortable seat experience after the subregion, and buttock ventilative groove prevents that the sponge from being stuffed the buttock for a long time and can't breathe freely.

Preferably, the seat frame plate is hollowed out with hip placement grooves at positions corresponding to the buttocks of the human body at the left side and the right side of the buttocks support area. So that the protruding muscles of the buttocks can be placed in the seat frame plate to relax, and the compression with the seat frame plate is reduced.

Preferably, the middle part and the two side edges of the front end of the seat frame plate are tilted to enable the front end of the seat to form a W-shaped structure. The W-shaped structure is used for placing thighs, distributes pressure between the thighs and the chair seat, and plays a role in relaxing the thighs.

Preferably, the backrest part is in an arc shape with a front convex upper part and a rear concave lower part in the middle, and the connecting part is in an arc shape with a front top of the rear concave upper part and the lower part in the middle, so that the whole chair back framework plate is in an S shape. The S-shaped back accords with the curve of the back of the human body, and comfortable and healthy back rest experience can be provided.

The principle and beneficial effects of the utility model adopting the technical scheme are as follows:

the utility model provides an ergonomic seat, which reduces the number of parts and the whole weight by integrally forming a chair back skeleton plate and a chair seat skeleton plate, and is provided with a spine pressure relief groove to provide a relaxation space for a spine.

Specifically speaking, through the vertical backbone pressure release groove that is equipped with the fretwork in the intermediate position of back of the chair skeleton board, backbone pressure release groove can hold user's back convex backbone to divide into two back backup pads that bilateral symmetry set up with back of the chair skeleton board, the back backup pad produces corresponding elasticity change when receiving leaning on the power, and the back of the user of elastic support, make this ergonomic seat have satisfied the user to the requirement of comfort level and health when having reduced quality and assembly degree of difficulty.
