Be elaborated below by most preferred embodiment and accompanying drawing concrete structure to massage armchair of the present utility model.In the accompanying drawing:

Fig. 1 is the schematic perspective view of this utility model one embodiment.

Fig. 2 is the front view of the chair back portion of this utility model one embodiment.

Fig. 3 is the side view of the chair back portion of this utility model one embodiment.

Fig. 4 be this utility model one embodiment chair back portion face action diagram.

Fig. 5 is the side-looking action diagram of the chair back portion of an embodiment of the present utility model.

Fig. 6 is the front view of another embodiment chair back portion of the present utility model.

As Fig. 1,2, shown in 3, the chair back 11 of massage armchair 10 of the present utility model, be to be provided with a shaped as frame chair back rack 20 in the chair back 11 inside, the both sides of chair back rack 20 form U-shaped opening slide rail 21 in opposite directions, in slide rail 21, be slidingly equipped with a travelling carriage 30, travelling carriage 30 two ends are slidedly arranged in the slide rail 21, one motor 22 also is housed on the chair back rack to be driven a screw rod 23 by belt and belt pulley and is used for driving a travelling carriage 30, make travelling carriage on 21 of the slide rails of chair back rack 20, move down, travelling carriage 30 both sides respectively are provided with the bogie side frame 31 that is parallel to slide rail 21, bogie side frame 31 drive another groups can 21 of two slide rails with travelling carriage on, mobile down bracing or strutting arrangement 40.

Provided bracing or strutting arrangement 40 and slide bar 41 on the bogie side frame 31, slide bar 41 two ends are fixed with the support 42 of two flat patterns respectively, and the two ends of support 42 are also sliding across 21 of two slide rails, and its end face is provided with ball-shaped masseur 43.

The total length of bracing or strutting arrangement 40 is about about half of chair back rack 20 total lengths.

Its action is as Fig. 2,3,4, shown in 5, if by Fig. 2, when 3 section start begins to move up, its travelling carriage 30 moves up, to top, bogie side frame 31 tops of travelling carriage 30 and bracing or strutting arrangement 40 during group support 42 root edges, whole bracing or strutting arrangement 40 sides begin to move up, at this moment, the masseur 43 of last group of support 42 is shored the back of user, make that this part is unlikely to be absorbed in the pressured of user back, after group support 42 is leaned by travelling carriage 30 on it, bracing or strutting arrangement 40 promptly moves thereupon, to Fig. 4, till the top shown in 5, and when travelling carriage 30 moves down, initial stage, its down group support 42 keep leaning support with the user back, lean the group support 42 of staying to travelling carriage 30 after, whole bracing or strutting arrangement 40 sides begin to move down.
