JP 2004-141622 A (page 10 FIG. 3 and FIG. 5) Japanese Patent Application Laid-Open No. 2004-283266 (Fig. 2 on page 5, Fig. 5 on page 6)

  By the way, this type of massage machine shown in FIGS. 19 and 20 is provided with a massage contact member such as a treatment element for performing a massage operation inside the backrest as a massage mechanism. When the contact member descends from above and reaches the vicinity of the seat, it is desirable to prevent a human body or a foreign object from being caught between the massage contact member and the rear end of the seat.

  As a preventive measure, for example, there is a method of providing an appropriate gap between the lowermost massage contact member and the rear end of the seat.

  However, in this case, although the massage contact member can sequentially massage the user's shoulders to the waist that are drowned in the backrest, the lowermost massage contact member and the rear end of the seat in the backrest The massage abutting member does not reach the user's buttocks located between the upper and lower parts, and therefore sufficient massage cannot be performed on the greater gluteal muscles provided in the buttocks.

  Temporarily, a sensor for preventing pinching between the massage contact member and the rear end of the seat is equipped to solve this problem, and the massage contact member is further lowered so as to reach the greater gluteal muscle. Even if it is configured to be movable, the massage contact member does not reach the greater gluteal muscle of the user's buttocks that are in contact with the surface of the rear end of the seat, and the part that contacts the lower end of the backrest It is thought that it can be massaged only to the greater gluteal muscle.

  In order to solve this, the massage machine shown in FIGS. 21 and 22 continuously forms a guide rail for moving the massage mechanism from at least the backrest portion to the seat portion, and the massage contact member of the massage mechanism It is configured to continuously massage the user's buttocks that abut from the backrest to the seat.

  However, this type of massage machine has the disadvantage that it cannot be made compact when transported or not used by folding it to face the seat as in the massage machine as shown in FIG. .

  Further, in the massage machine shown in FIGS. 21 and 22, the backrest and the seat have a substantially flat portion for supporting the human body (human body support member), and the backrest and the seat are connected to each other. Only the part to be formed is small and curved. In such a configuration, for example, when a seated user unexpectedly shifts forward in the seat, for example, by changing his / her posture, the lower side of the buttocks is seated as shown in FIG. However, the back side of the buttocks is detached from the surface of the backrest part, and even if the massage contact member reaches the position on the back side of the buttocks, massage the large gluteal muscle at this position sufficiently. The problem that cannot be done.

  Conversely, when a user who is lying on the reclining chair body shifts backward in the backrest, the back side of the buttocks is supported by the backrest, but the lower part of the buttocks is the surface of the seat Will cause problems similar to those described above.

  Accordingly, the present invention has been made to solve the above-described problems, and has a compact configuration suitable for transportation and when not in use, and the human body even if the human body support member is displaced. It is an object of the present invention to provide a massage machine capable of preventing the human body from being detached from the support member as much as possible and sufficiently massaging the greater anterior muscles and the surrounding muscles without any wrinkles.
