Massage armchair frame structure

Abstract

The invention relates to a massage armchair frame structure which comprises a seat frame (1), a back frame (2) and a supporting plate (6) for supporting a guide rail (3) for a massage movement to walk. The massage armchair frame structure is characterized in that the first end of the back frame (2) is hinged to the seat frame (1), a driving device (4) driving the back frame (2) to rotate with respect to the seat frame (1) is in driving connection with the back frame (2), the supporting plate (6) comprises a first portion (61) supported and arranged on the seat frame (1) and a second portion (62) supported and arranged on the back frame (2), the first portion (61) is connected with the second portion (62) through a middle portion (63), and at least the middle portion (63) of the supportingplate (6) is of a flexible structure. The massage armchair frame structure can achieve stepless regulation of a relative angle of the back frame and the seat frame, and accordingly achieve rising andtitling actions of a backrest to meet the requirements for comfortable leaning of different users. The massage movement can walk from the head to the thighs no matter in which states a massage armchair is.

Description

technical field [0001] The invention relates to a massage chair, in particular to a frame structure of a massage chair. Background technique [0002] Existing massage chairs on the market generally adopt the walking massage movement to massage the human body, and the massage track structure is usually integrated. Movement massage can be roughly divided into three types. When the massage track adopts the overall guide rail form corresponding to the natural curve of the human body, the movement massage range can be from the head to the thigh. Although this type of massage has a large range, the seat part The position relative to the back cannot be adjusted, and the angle of the guide rail cannot be adjusted, which cannot meet the comfort angle requirements of the user; when the back frame and the seat frame are split, the angle between the two can be adjusted arbitrarily, but the walking range of the massage movement is limited. However, the massage from the head to the thigh...

Problems solved by technology

Movement massage can be roughly divided into three types. When the massage track adopts the overall guide rail form corresponding to the natural curve of the human body, the movement massage range can be from the head to the thigh. Although this type of massage has a large range, the seat part The position relative to the back cannot be adjusted, and the angle of the guide rail cannot be adjusted, which cannot meet the comfort angle requirements of the user; when the back frame and the seat frame are split, the angle between the two can be adjusted arbitrarily, but the walking range of the massage movement is limited. However, the massage from the head to the thigh can only be realized when walking in the back range or only in the lying position, and it is often impossible to increase the movement massage while meeting the user's arbitrary comfort angle requirements. scope
