pinions

65 and 68 and the

guide rollers

66 and 69 are connected in the reclining state, a substantially trapezoidal shape with a long bottom is seen in a side view. By arranging the

pinions

65 and 68 and the

guide rollers

66 and 69 as described above, the massage unit 9 can smoothly pass through the curved portion 22d of the guide member 22 that is convex downward in the reclining state.

In this embodiment, when the pair of

pinions

65 and 68 and guide

rollers

66 and 69 are positioned on the straight portion 22c or the straight portion 22e both in the upper and lower directions, the distance (gap) D2 between the rail portion 22b and the

guide rollers

66 and 69 is The positional relationship between the

pinions

65 and 68 and the

guide rollers

66 and 69 is set so as to be very small (1.2 mm in this embodiment).

The massage unit 9 is moved from the straight part 22e corresponding to the backrest part 4 to the seat part 3 side, and as shown in FIGS. 17 and 18, immediately after reaching the curved part 22d of the lower pinion 65, massage is performed. The inclination of the unit 9 hardly changes, and the center C2 of the guide roller 66 is located closer to the seat part 3 than the center C1 of the pinion 65, so that the distance (gap) D2 between the rail part 22b and the guide roller 66 is slight.

guide rollers

66 and 69 will bite into the rail part 22b. However, in this embodiment, since the

guide rollers

66 and 69 are configured to be elastically deformable, the biting of the

guide rollers

66 and 69 into the rail portion 22b can be absorbed.

Hereinafter, a method for detecting a specific part (shoulder position) of the user by the massage unit 9 will be described. The initial position of the lift position of the massage unit 9 is located at the front end portion of the seat portion 3. Then, the user operates the remote controller 100 to select an automatic course in which the massage units 9 to 12 operate with preset contents stored in the control unit 13. When the automatic course is selected, the control unit 13 controls the massage unit 9 to rise from the front end portion of the seat portion 3 toward the upper end portion of the backrest portion 4. In the lift position where the user's body part exists, a load is applied to the massage means 62 from the user, so that the moving frame 61 moves back to the reverse position against the urging force forward by the urging means 89 ( 14). When the massage unit 9 reaches the shoulder position of the user, the load on the massage means 62 from the user is released, and the moving frame 61 is protruded by the forward biasing force by the biasing means 69 (see FIG. 15). ).

Then, the shoulder position of the user is determined by the lift sensor 83 detecting the lift position of the massage unit 9 when the advance / retreat sensor 86 detects the protruding position of the moving frame 61. The detected shoulder position is stored in the control unit 13, and an automatic course is started. The shoulder position may be detected in the process of lowering the massage unit 9 from the upper end of the backrest 4. In this case, the elevation position of the massage unit 9 when the advance / retreat sensor 86 detects that the moving frame 61 is retracted from the protruding position (see FIG. 15) is detected by the elevation sensor 83 to determine the shoulder position. That's fine.
