Description

Technical Field

[0001] The invention belongs to the field of health massagers, and in particular relates to a conversion mechanism between the functions of a massage chair and a general-purpose armchair or sofa chair, and is also applicable to a reclining chair or a rocking chair. Background Art

[0002] Although the existing massage chair can achieve the effect and purpose of massage, the kneading layer structure of the backrest of the massage chair must be completely relaxed so as not to interfere with or hinder the telescopic range of the massage wheel. When the human body sits on the massage chair to rest (without massage activity or resting after massage):

[0003] 1. Because there is no tension in the kneading layer of the backrest, when the body leans back in a relaxed state, the body will sink backward accordingly.

[0004] 2. The massage wheel will always contact the back and waist of the person, which will cause discomfort after a while. Due to the above reasons, the existing massage chair can only be used when massage is needed because of its single function.

[0005] If you want to change or add existing functions, you need to change the following:

[0006] 1. Tighten the kneading layer of the massage chair back appropriately.

[0007] 2. Retract and store the massage wheels away from the contact points on the back and waist of the human body.

[0008] After this improvement, the massage chair is converted into a (multifunctional) universal reclining chair or sofa chair, so that people can sit on the chair for a long time to rest, work and entertain more comfortably, and the multifunctional role of the massage chair can be brought into play to benefit mankind!
