Can be given to a person's thigh.

Similarly, the second bag 5 for the seat, which presses against the buttocks of the user, also expands when its front edge 5b moves toward the backrest 3 when it expands. Due to the expansion of the second bag body 5 for the seat accompanying such displacement, an expansion force including a large amount of expansion components in the direction of the back as shown by the arrow in FIG. Can be given to the buttocks of the elderly.

As a result, the body of the user sitting on the chair body 1 is less likely to escape upward, and the body of the user is restricted from moving backward by the backrest 3. 7 (A) and 7 (B), the body does not run backward due to the compression force in the direction of the arrow in FIG.

Further, as described above, the front and rear edges 4b, 5b of the first and second bag portions 4, 5 for the seat portion expand while approaching the fixing portions 4a, 5a, so that the fixing portions 4a, 5a are formed. Does not restrict the inflation of the first and second bags 4,5 for the seat. Therefore, the first and second bags 4 and 5 for the seat can be largely inflated.

As described above, in addition to the reduction of the compressive force on the body caused by the escape of the body due to the expansion of the first and second bags 4, 5 for the seat portion, it is possible to reduce the reduction in the pressure on the body. Since the degree of inflation of the bodies 4 and 5 is large, the inflation strongly presses the buttocks and thighs of the user, so that massage of these parts can be effectively performed.

Similarly, the fixing portion 10a consisting of only the upper edge of the backrest portion bag 10 is arranged on the upper end side of the backrest portion 3 and the backrest portion bag 10 is fixed to the backrest portion 3. Thus, the backrest portion bag body 10 is free to move at its lower edge 10b (see FIG. 5) and expands toward the fixed portion 10a. Thus, an expansion force including a large amount of upward expansion component is applied to the back of the user as shown by an arrow in FIG. 7C, not to the front of the back of the user supported by the backrest portion 3. Reduce the escape of the body forward and extend the spine upward from below. In addition, since the lower edge 10b of the backrest portion bag 10 expands while approaching the fixing portion 10a as described above, the fixing portion 10a is
Without restricting the inflation of the bag, the bag 10 is greatly inflated and presses the back of the user as described above.

As described above, in addition to being able to reduce the reduction of the compressive force on the body caused by the escape of the body accompanying the inflation of the backrest portion bag 10, the degree of expansion of the bag 10 is large. Due to the inflation, the back muscle of the user is strongly pressed, so that the back muscle can be effectively massaged. Moreover, since the back muscles are extended upward from below in this massage, the back muscles can be stretched.

Further, the first and second bags 4 and 5 for the seat portion are
Then, only the edge is fixed to the seat portion 2 as the fixing portions 4a and 5a. Similarly, the backrest portion bag body 10 is fixed to the backrest portion 3 only with the upper edge as the fixing portion 10a. The number of attachment points of the bodies 4, 5, and 10 to the chair body 1 can be reduced by half as compared with the related art. Therefore, each bag 4, 5, 1
