Sofa massage chair frame with T-type backrest mechanism

Abstract

The invention relates to a sofa massage chair frame with a T-type backrest mechanism, which comprises a massage chair frame bracket consisting of a group of side support frames arranged side by side; the back supporting mechanism comprises a transverse supporting piece fixedly connected between the upper sides of the side supporting frames, and a longitudinal supporting piece extending in the direction of the spine of the human body is vertically locked and fixed to the transverse supporting piece; the massage machine core comprises a massage mechanism, a reciprocating driving mechanism used for driving the massage mechanism to reciprocate and a vertical driving mechanism used for driving the massage mechanism to vertically move, and when the massage mechanism reciprocates to pass through the transverse supporting piece, the massage mechanism is driven by the vertical driving mechanism to move vertically. When the massage mechanism descends until the massage wheels are located on the bottom side of the transverse supporting piece and moves back and forth to leave the transverse supporting piece, the massage mechanism ascends until the massage wheels are located on the upper side of the transverse supporting piece under the driving of the vertical driving mechanism. According to the sofa, the comfort of the sofa can be kept, and a reasonable massage effect can be achieved.

Description

technical field [0001] The invention relates to a sofa massage chair frame with a T-type backrest mechanism, which not only has the comfort of a sofa, but also has sufficient massage functions. Background technique [0002] A sofa is a kind of upholstered furniture. In order to ensure the support of the sofa back support, the existing sofa back support is generally provided with a corresponding back board, and then the cushion is installed on the back board. Under the obstruction of the back-to-board, the existing sofa cannot be installed with a massage mechanism. Even if there are a small number of sofas with a massage mechanism, it can only perform local fixed massage on the position where the back support is not provided with a back-to-board Mechanism settings, simply can not achieve a reasonable massage effect.

Problems solved by technology

Under the obstruction of the back-to-board, the existing sofa cannot be installed with a massage mechanism. Even if there are a small number of sofas with a massage mechanism, it can only perform local fixed massage on the position where the back support is not provided with a back-to-board Mechanism settings, can not achieve a reasonable massage effect

[0003] Even some existing massage structures that use back support often use a support structure that fits most of the back of the human body as a whole, directly supporting the user's entire back or a wide range of back, so as to achieve the effect of support. However, if this support structure is used, the massage movement needs to sink for a long time to pass through the back support structure. The blank period of the user's massage period is longer, and the overall experience will be affected.
