Description

Massage chair

Technical Field

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

Background

The chairs can be classified into massage chairs and leisure chairs according to different functions.

The leisure chair refers to a chair which is used for people to enjoy leisure time; the chair is not formal like a dining chair and an office chair, has small personality, such as a reclining chair can be formed, and a footrest can be arranged, so that the comfortable sensation of the body can be brought to people, and further, the deep relaxation feeling of the people can be brought;

the massage chair mainly simulates manual massage, but only utilizes mechanical rolling force and mechanical force extrusion to massage; the massage chair can carry out deep massage along the spine according to the curve of the human body and by adopting various massage techniques such as swinging, finger pressing, pinching, massaging and kneading and the like through the massage machine core; just as if someone were pounding their back and rubbing their shoulders; thereby relieving the fatigue of the body;

the specific structure of the massage movement can refer to the massage movements related to CN2922880Y, CN100382775C, CN202505713U, CN208448086U, CN109620672A, CN109846683A, CN100581523C, CN109248042A, CN109259995A, CN208448086U, TW201410230A, CN110353963A, CN110314078A, CN109172253A, CN209392344U and CN209392345U, generally speaking, the massage movement realizes a plurality of massage techniques such as swinging, acupressure, kneading and massaging through the massage rollers, but the existence of the massage rollers makes the massage chair only suitable for relieving fatigue and not as an appliance for long-time rest; further, in the market, the leisure chair and the massage chair become two types of clear chairs, and the functions of the two types of chairs are difficult to be obtained at the same time.

Chinese patent document No. CN109620673A discloses an angle-adjustable massage manipulator, which comprises an installation frame and a massage head assembly, wherein the massage head assembly comprises a crank arm and a massage head, the massage head is arranged on the crank arm, the installation frame is further provided with a kneading assembly for driving the crank arm and the massage head to move, the kneading assembly comprises a kneading shaft rotatably arranged on the installation frame, the crank arm is rotatably arranged on the kneading shaft, the installation frame is provided with an adjusting mechanism capable of adjusting the rotation angle of the crank arm, the adjusting mechanism comprises a rotation seat rotatably arranged on the installation frame, the rotation seat can drive the crank arm to rotate to realize the angle adjustment of the crank arm, and the installation frame is provided with a driving assembly capable of driving the rotation seat to rotate; through adopting above-mentioned scheme, the first angle of adjustable massage of this massage manipulator is convenient for accomodate, and the travelling comfort is better.

Wherein, the final purpose that massage manipulator was convenient for to accomodate just makes the massage armchair use as leisure chaise longue, but the cloth cover of massage armchair has good massage effect in order to guarantee, and the cloth cover of massage armchair mainly has two kinds of ways at present: firstly, the elasticity at the regional cloth cover of massage is very big, secondly the cloth cover in massage region is much bigger than the regional area of massage, and then make the cloth cover in massage region just can not form the massage action to the massage gyro wheel and block, but this also makes the cloth cover of massage armchair no longer have the effect of supporting the human body, it mainly supports the vertical metal strip for massage armchair inside, even both accomodate the back when the massage gyro wheel of massage core, people sit when having a rest on the massage armchair in a trip, though not having the puzzlement that the massage gyro wheel led to the fact the human body, but because support the vertical metal strip for massage armchair inside, after the longer time, people just can feel very uncomfortable.
