Problems solved by technology

With the above scheme, the angle of the backrest frame can be adjusted, and the massage device can slide back and forth between the backrest frame and the seat frame, with a massage function. There is no deformation of the rack, which will not affect the matching accuracy of the walking gear and the curved rack, but whenever the massage device passes through the transition rack, it will deflect the transition rack, and the transition rack can only make the massage device stay at the designated position. Therefore, when the transition rack does not cooperate with the rack rack or the rack rack during the rotation process, the massage device will be stuck
[0007] In addition, the seat frame in this device does not move, and the angle adjustment is realized by rotating the backrest frame through the expansion and contraction of the electric push rod, thereby solving the technical problem of the decline in massage comfort caused by the inclination of the seat, but it is obvious that The support of the entire backrest frame can only be realized by the electric push rod, and the scalability of the electric push rod leads to the instability of its support for the backrest frame
