There are two guide rails, which are arranged in parallel with each other; the massage movement 91 is arranged on the connecting base 92, and both ends of the connecting base 92 are connected with gears 93 respectively engaged with the two guide rails.

The massage movement walking track includes:

The guide rails include a first guide rail 31 and a second guide rail 32 respectively arranged on the seat frame 1 and the back frame 2. The first guide rail 31 and the second guide rail 32 are connected by a third guide rail 33. Flexible guide rails that are bent and deformed.

In this embodiment, the first guide rail 31 , the second guide rail 32 and the third guide rail 33 are all racks, and the first guide rail 31 , the second guide rail 32 and the third guide rail 33 are integrally formed.

The backs of the first guide rail 31 , the second guide rail 32 and the third guide rail 33 are provided with a plurality of protruding posts 35 at intervals; the back frame 2 is provided with a positioning hole for accommodating one of the protruding posts 35 (not shown in the figure) , the positioning hole and the corresponding convex column 35 are in tight fit.

The flexible connecting plate 4 is also provided with limiting holes 52 for accommodating other protruding posts 35 . The limiting holes in this embodiment are waist-shaped holes, and the limiting holes 52 are loosely fitted with the protruding posts 35 to facilitate angle adjustment. When the rack is deformed, the protruding post 35 can slip slightly in the limiting hole 52 .

A plurality of transversely arranged support ribs 34 and a longitudinal support rib arranged along the length direction of the rack are provided at intervals on the bottom surface of the rack. The arrangement of the support rib increases the strength of the rack on the one hand, and provides elasticity for the deformation of the rack on the other hand.

The connecting plate 4 is the supporting base of the third guide rail 33 , and is a flexible connecting plate that can be deformed in the longitudinal direction. The connecting plate 4 is connected between the seat frame 1 and the back frame 2 .

The connecting plate 4 includes a plurality of chain links 41 hinged in sequence along the length direction of the connecting plate 4 ; adjacent chain links 41 are hinged through connecting shafts 42 .

Each chain link 41 includes a plate-shaped base plate 414, and a first side of the base plate 414 has a first convex block 411 and a second convex block 412, which are arranged at intervals; A third bump 413 is provided on the second side opposite to the first side plate of the base plate 414 ; the gap between the first bump 411 and the second bump 412 can accommodate the third bump 413 The bump 413 shall prevail;

The first bump 411 , the second bump 412 and the third bump 413 are all provided with shaft holes 415 which are adapted to the connecting shaft 42 .

Both the first side and the second side of the base plate 414 are recessed inward to form an arc-shaped groove 416 which is matched with the connecting shaft 42 .
