As described above, the seat chair type massage machine 1 according to the present embodiment is characterized in that the backrest part 4 falls backward in the rear part of the seat part 2 when the user is not seated (before seating). The fall prevention member 80 is provided so that the fall prevention member 80 can be moved back and forth with respect to the seat portion 2.
In this way, by providing the rear part of the seat part 2 with the fall-preventing mechanism 79 that can be moved back and forth freely, the seat part 2 of the sitting chair type massage machine 1 can be fallen backward when placed on the floor surface. Therefore, the standing state can be maintained independently.

By the way, as shown in FIG. 6, the seat portion 2 is configured to be foldable so as to overlap with the backrest portion 4.
Specifically, a pair of folding mechanisms 87 are provided in the width (left and right) direction of the seat chair type massage machine 1 between the rear part of the seat part 2 and the lower part of the backrest part 4. The folding mechanism 87 includes a projecting piece 88 projecting upward at the rear portion of the seat portion 2 and a pivot member (not shown) that is built in the lower portion of the backrest portion 4 and pivotably supports the projecting piece 88.

The protruding piece 88 is a plate piece having a predetermined height in the vertical (longitudinal) direction, and a hole (not shown) is formed in the upper part. The pivot member is a plate piece that is long in the vertical (longitudinal) direction, and a hole is formed in the lower part. The pivotal support member pivotally supports the protruding piece 88 after the hole formed in the lower portion and the hole of the protruding piece 88 are combined.
When the protruding piece 88 swings upward with respect to the pivot member, the seat portion 2 is folded so as to overlap with the backrest portion 4, and the thickness in the front-rear direction of the seat chair type massage machine 1 is thereby folded. Can be made thin and compact (see FIG. 6). Further, when the projecting piece 88 swings downward with respect to the pivot member, the seat portion 2 can be pulled out, allowing the user to be seated on the seat portion 2 and leaning against the backrest portion 4. This is possible (see FIG. 1).

Below, the operation | movement aspect of the massage mechanism 8 of this embodiment mentioned above is demonstrated.
When using the sitting chair type massage machine 1 incorporating the massage mechanism 8 of the present embodiment, first, the seat 2 shown in FIG. 6 is started from the folded state so as to overlap the backrest 4.
As shown in FIGS. 1 and 2, the seat portion 2 is pulled out from the folded state so as to be in the horizontal direction, and the frame member 3 of the fall prevention member 80 is pulled out rearward from the seat portion 2. That is, the user places the sitting chair type massage machine 1 on the floor surface in a state where the backrest portion 4 is substantially upright. And after setting it in such a mounting state, a user sits on the seat part 2.

Then, the massage mechanism 8 is driven, and a massage effect is imparted from the user's shoulder to the top and bottom of the waist (back).
The sitting chair type massage machine 1 may be placed on a normal chair or sofa, and then sit on the sitting chair type massage machine 1, and the massage mechanism 8 may be driven to receive massage. It is possible (modification example).

  As described above, the seat chair type massage machine 1 of the present embodiment is intended to be used after being placed on the floor surface, so that the user can sit relaxed on the floor surface. Thus, the seat portion 2 is large (particularly long in the front-rear direction). Therefore, when the seat chair type massage machine 1 is placed on a normal chair or sofa, the seat portion 2 of the seat chair type massage machine 1 protrudes from the front end of the seat surface of the normal chair or sofa. There is a fear. In this case, it is difficult for the user to sit down.

  Therefore, as shown in FIG. 7, the seat chair type massage machine 1 according to the modification is divided into two members at the front portion of the seat portion 2 (for example, at a length of 1/3 in the front-rear direction from the front end). The front side (front seat portion 2A) of the two members and the rear side (rear seat portion 2B) of the two members are connected by a connecting member such as a flexible cloth member, and the rear seat The front seat portion 2A can be bent in a suspended state with respect to the portion 2B. However, since the front seat portion 2A and the rear seat portion 2B are connected by the connecting member, the front seat portion 2A and the rear seat portion 2B are not separated.

  When the seat chair type massage machine 1 having the above-described configuration is placed on a normal chair or sofa, the front seat portion 2A that protrudes from the front end of the seat surface of the normal chair or sofa is removed. Can be folded down. By doing in this way, the inconvenience that the seat part 2 of the seat type massage machine 1 protrudes from the front end part of the seat surface of a normal chair or sofa can be avoided. It is possible to sit on 2B) and receive massage in a relaxed posture.

By the way, in this embodiment, although the U-shaped frame member 3 was illustrated as the fall prevention member 80, the fall prevention member 80 is not limited to this form.
For example, the fall prevention member 80 may be formed of a rectangular plate that faces in the left-right direction, and one side in the longitudinal direction thereof is attached to the back of the lower portion of the seat portion 2 so as to be swingable in the front-rear direction. When such a fall-preventing member 80 is used, the rectangular fall-preventing member 80 is swung to the rear of the seat 2 and protrudes to the rear of the seat 2 to fix the position with respect to the seat 2. It is good to realize the state. Conversely, when the fall prevention member 80 is not used, the rectangular fall prevention member 80 is preferably swung forward of the seat portion 2 and folded so as to be attached to the lower surface of the seat portion 2.
