Abstract

The utility model relates to a seat manufacturing and designing field, concretely relates to elasticity provides device suitable for seat. The utility model relates to a can realize through following technical scheme: the utility model provides an elasticity provides device suitable for seat, contains the main part, contain two sets with the rotatory assembly that the main part is connected, every set rotatory assembly contain with the main part rotate the linking arm of being connected and with the supporter that the linking arm is connected, two sets rely on elastic connection body to connect between the rotatory assembly. An object of the utility model is to overcome prior art not enough, provide an elasticity provides device suitable for 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.

Description

Elasticity providing device suitable for seat

Technical Field

The utility model relates to a seat manufacturing and designing field, concretely relates to elasticity provides device suitable for 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 elasticity provides device suitable for 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 elasticity provides device suitable for seat, contains the main part, contain two sets with the rotatory assembly that the main part is connected, every set rotatory assembly contain with the main part rotate the linking arm of being connected and with the supporter that the linking arm is connected, two sets rely on elastic connection body to connect between the rotatory assembly.

As the utility model discloses a preferred, elastic connector is elastic band, elastic ring or elastic cloth.

As an optimization of the present invention, the elastic connecting body is a spring.

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

As a preferred aspect of the present invention, the connecting arm is connected to the main body through a main shaft.

As the utility model discloses a preferred, the supporter pass through the counter shaft with the linking arm rotates to be connected.

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

1. the support body can rotate, so that the sitting posture of a human body is adapted, and the waist is supported timely.

2. The elastic connecting body is used as an elastic component, the structure is simple, the implementation is facilitated, and the cost of the whole seat is controllable.

Drawings

FIG. 1 is a schematic diagram of a first embodiment;

FIG. 2 is a schematic view of the support body portion of FIG. 1 after being returned to its original position;

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, the main body 1 may be a frame, and the frame may be a thermoplastic material or a rigid material. On both sides of the main body 1, a set of rotating assemblies is respectively arranged on the left and the right, specifically, one end of the connecting arm 3 is rotatably connected to the main body 1 through a rotating component in the prior art, such as a rotating shaft, a bearing, etc., and the other end of the connecting arm 3 is provided with a support 4. The supporting body 4 can be a back plate for supporting the back of the user, or a waist rest for supporting the waist of the user, and the principle is the same. The support body 4 is also rotatably connected to the other end of the connecting arm 3 via the auxiliary rotating shaft 6, and an elastic member such as a torsion spring may be fitted around the auxiliary rotating shaft 6 in order to improve the restorability of the support body 4.

In this case, an elastic connecting body 5 is provided between the two support bodies 4 to allow the support bodies 4 to move in accordance with the movement of the user's back. The elastic connecting body 5 can be implemented in various ways, such as a spring, an elastic cowhide band, an elastic rubber ring, a cloth made of elastic fabric, an elastic strip, etc. When the user moves back to the rear, i.e. fig. 1, the connecting arm 3 swings back, the distance between the two supporting bodies 4 is pulled apart, and the elastic connecting body 5 is pulled apart. The state of fig. 2 occurs when the back and waist of the user move forward. The elastic connecting body 5 retracts due to the elasticity of the elastic connecting body, the distance between the two supporting bodies 4 is shortened, the connecting arm 3 swings, the two supporting bodies 4 move forwards, and the two supporting bodies are attached to the waist and the back of the human body again.

The technical purpose of present case is on the one hand in order to let supporter 4 can laminate human back always, provides real-time laminating effect, and on the other hand reduces the part, reduces the structure for use minimum economic cost realizes technical scheme.
