Description

Massage backrest

Technical Field

The invention relates to a massage backrest, in particular to a massage backrest with a movement and a shell capable of being opened and closed left and right.

Background

The existing backrest with the massage function on the market has the advantages that the machine core and the shell are integrated and cannot be opened and closed left and right. Because the left side and the right side of the back of the human body have certain angles, the massage chair cannot be well attached to the back of the human body, and has certain defects in massage body feeling. For example, chinese utility model CN201042499Y discloses a walking kneading massage device, which simulates a manual walking kneading massage mode through a motor and a gear transmission mechanism. In practical use, the massage machine core and the shell are of a plane structure, so that the massage machine core cannot be well attached to the back of a human body.

Meanwhile, a movement which can be opened and closed on the left and the right is also available on the market, for example, the Chinese utility model CN202844073U discloses a folding type massage movement which is provided with two massage units, wherein the two massage units are folded in a hinge shape and reset to a specific included angle, and the curvature of the curve of the human body is fitted. But the folding massage machine core is only suitable for throw pillow and waist rest type massage products, and has a narrow application range.
