Description

Elastic connection structure suitable for supporter seat

Technical Field

The utility model relates to a seat manufacturing and designing field, concretely relates to elastic connection structure suitable for supporter seat.

Background

The chair is a piece of furniture with wide application in daily life and work, generally comprises a base, a backrest, a supporting structure, armrests and other parts, and in order to meet personalized requirements of people and bring more comfortable and healthy use experience, the structure and the function of the chair are continuously improved. When a user uses the seat, the user usually supports the buttocks and the back by the base and the backrest, the support of the waist is relatively weak, the muscle and the vertebra of the waist and the back of the human body bear the pressure of the weight of the upper part of the human body, and in the long term, lumbar muscle strain and vertebra pathological changes can occur, so that inconvenience in study, life and work is brought to people.

In recent years, in order to provide a supporting force to the waist, a seat with a waist support is on the market, and the waist support is connected to a base or a backrest to provide a good supporting force to the waist of a user, so that the user can keep a sitting posture upright and has a good protection function to the lumbar. However, the existing lumbar support seat has the defect that the lumbar support is not tightly attached to the human body, namely, when the sitting posture of a user is adjusted, such as forward leaning, the lumbar support cannot be adjusted in a telescopic mode along with the movement of the human body, the lumbar support cannot be attached to the human body to support the waist continuously, and the using effect of the lumbar support is not ideal.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide an elastic connection structure suitable for supporter seat. When the user moves back and forth on the seat, the waist support can cling to the waist and the back of a human body to move synchronously, the waist is attached to the waist in real time, and the supporting force for the waist of the human body is increased.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides an elastic connection structure suitable for supporter seat, contains the main part, still contain with the main part rotates the rotatory assembly of being connected, rotatory assembly contain the swinging boom and connect in supporter on the swinging boom still contains and is used for connecting the main part with the elastomer of rotatory assembly.

As the utility model discloses a preferred, the elastomer is the torsional spring, torsional spring one end with rotatory assembly connects, the other end with the main part is connected.

As a preference of the present invention, the main body and the rotating assembly are connected by a fixed shaft.

As a preference of the present invention, the main body includes a fixing plate, and the rotation assembly includes a housing connected to the rotating arm and a rotation connector connected to the housing.

as the utility model discloses a preferred, the elastomer is the torsional spring, torsional spring one end with swivelling joint spare is connected, the other end with the fixed plate is connected.

Preferably, the support body is a backrest or a waist support.

To sum up, the utility model discloses following beneficial effect has:

1. The waist support or the backrest can move back and forth by being attached to the human body and is always attached to the human body.

2. Practical components and a simple structure are adopted, so that the manufacturing and processing costs are effectively controlled.

Detailed Description

the present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Embodiment 1, as shown in fig. 1 and 2, fig. 1 is a side sectional view of the embodiment, and fig. 2 is a plan view of the embodiment. The main body 1 is a chair frame part, and can be made of plastic or metal. The main body 1 includes a fixing plate 11. The rotating assembly 2 comprises a rotating arm 21, one end of the rotating arm 21 is connected with a supporting body, the supporting body can be a waist rest or a backrest, and the principle is the same. The other end of the rotating arm 21 is connected with a shell, and the shell 22 is sleeved on the fixed shaft 3 and can move around the fixed shaft 3.

When the user leans backward against the support body, the rotating arm 21 rotates about the fixed shaft 3. The rotating arm 21 drives the housing 22 to rotate, and the housing 22 drives the rotating connecting piece 23 to rotate. As shown in fig. 1, the fixed plate 11 is below the rotary joint 23. In the present case, the elastic body 4 is a torsion spring, and the torsion spring is sleeved on the fixed shaft 3. One end is connected with the rotary connecting piece 23 and is butted against the other end is connected with the fixed plate 11 and is butted against the rotary connecting piece. When the rotary connector 23 rotates, the fixed plate 11 is fixed, and thus the torsion spring is compressed, generating a torsion force. When the waist and the back of the user move forwards, the torsion generated by the torsion spring drives the supporting body to move forwards to be attached to the waist and the back of the human body.

As shown in fig. 3 and 4, fig. 3 and 4 are schematic views of a second embodiment and a third embodiment, and the difference between the second embodiment and the third embodiment and the first embodiment is the specific structure of the elastic body 4. In the first embodiment, the elastic body 4 is a torsion spring, and in the second and third embodiments, the elastic body 4 is a compression spring and a tension spring, respectively. As shown in fig. 3, the user leans back, the rotary connector 23 rotates, and the compression spring is connected to the rotary connector 23 at one end and the fixed plate 11 at the other end, is compressed, and generates elastic force. In fig. 4, the user leans back, the rotary connector 23 rotates, the elastic body 4 is a tension spring, one end of the tension spring is connected to the rotary connector 23 and is elongated, and the other end of the tension spring is connected to the fixing plate 11 and is fixed, so that tension is generated.

the technical scheme not only can ensure that the waist support or the backrest can be attached to the human body to move back and forth and be attached to the human body all the time, but also adopts practical components and simple structures, thereby effectively controlling the manufacturing and processing cost.
