Description

a massage chair

technical field

The invention relates to the technical field of furniture, in particular to a massage chair.

Background technique

According to different functions, chairs can be divided into massage chairs and leisure chairs. Leisure chair refers to the chair we usually use to enjoy our leisure time; this kind of chair is not as formal as dining chairs and office chairs, it has some small characters, such as it can be formed as a reclining chair, or it can be set with footrests, so that it can give people a sense of comfort. It brings the comfort of the body, and then brings people a deep sense of relaxation; the massage chair mainly imitates manual massage, but it uses mechanical rolling force and mechanical force to squeeze for massage; the massage chair can follow the curve of the human body. Along the spine and through the massage movement, a variety of massage techniques such as rocking, acupressure, pinching, pushing and kneading are used for deep massage; it is as if someone is beating their backs and rubbing their shoulders; and thus relieve physical fatigue;具体结构可参考公开号为CN2922880Y，CN100382775C，CN202505713U，CN208448086U，CN109620672A，CN109846683A，CN100581523C，CN109248042A，CN109259995A，CN208448086U，TW201410230A，CN110353963A，CN110314078A，CN109172253A，CN209392344U，CN209392345U等专利文献中所涉及的按摩机芯，一般For example, the massage movement uses the massage roller to realize various massage techniques such as rocking, acupressure, pinching, pushing and kneading, but it is precisely because of the existence of the massage roller that the massage chair is only suitable for relieving fatigue, not as a long-term It is a tool for time rest; thus, on the market, leisure chairs and massage chairs have become two distinct types of chairs, and it is difficult to have both functions.

The Chinese patent document with publication number CN109620673A discloses an angle-adjustable massage manipulator, including a mounting frame and a massage head assembly, the massage head assembly includes a curved arm and a massage head, and the massage head is arranged on the curved arm, The mounting frame is also provided with a kneading assembly that drives the action of the crank arm and the massage head. The mounting frame is provided with an adjustment mechanism that can adjust the rotation angle of the crank arm, the adjustment mechanism includes a rotation seat, the rotation seat is rotatably arranged on the installation frame, and the rotation seat can drive the crank arm to rotate to realize the angle adjustment of the crank arm, The mounting frame is provided with a driving component that can drive the rotating seat to rotate; by adopting the above solution, the massage manipulator can adjust the angle of the massage head, which is convenient for storage and more comfortable.

Among them, the ultimate purpose of the convenient storage of the massage manipulator is to make the massage chair can be used as a leisure chair. However, in order to ensure a good massage effect, the cloth cover of the massage chair mainly has two methods: one is in the massage area. The elasticity of the cloth cover is very large, and the second is that the cloth cover in the massage area is much larger than the massage area, so that the cloth cover in the massage area will not block the massage action of the massage roller, but this also makes the massage The cloth cover of the chair no longer has the function of supporting the human body, and its main support is the vertical metal strip inside the massage chair. There is no trouble caused by the massage roller to the human body, but because the support is a vertical metal strip inside the massage chair, people will feel very uncomfortable after a long time.

technical problem

In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a massage chair, which can solve the diaphragm induction on the human body caused by the massage rollers in the massage movement when not massaging, so that the massage chair can also be used as a leisure chair.
