A base end portion of the support member 67 is attached to the upper end frame 22 via a hinge 68. As shown in FIG. 12B, the support member 67 and the main body 66 are tiltable in the front-rear direction in the region on the rear side of the upper end frame 22 with the hinge 68 as the rotation center.

  As shown in FIG. 11A, a belt insertion portion 65 a penetrating in the left-right direction is formed on the rear surface of the pillow 65. The head support belt 60 is inserted through the belt insertion part 65a. Thereby, the rear surface of the pillow 65 is supported by the head support belt 60.

  In the body posture assistance tool 1A of the second embodiment, when the face of the patient M is directed in the front direction, the head support belt 60 is interposed between the support frames 24 and 24 as shown in FIG. To reduce the slack. Thereby, as shown in FIG. 12A, the pillow 65 is supported by the head support belt 60 in a vertically raised state, and the face of the patient M is directed in the front direction.

Further, in the body posture assistance tool 1A of the second embodiment, when the face of the patient M faces upward, as shown in FIG. 11B, the head support belt 60 is interposed between the support frames 24, 24. Increase the slack. Accordingly, as shown in FIG. 12B, the pillow 65 is tilted backward while being supported by the head support belt 60, and the face of the patient M faces upward.
Furthermore, when returning the face of the patient M from the upward direction to the front direction, as shown in FIG. 12A, the slack of the head support belt 60 is reduced, and the pillow 65 is tilted forward. Then, the head Ma of the patient M is raised.

  In the postural assistance tool 1A of the second embodiment as described above, as shown in FIG. 12B, the pillow 65 can be tilted backward by loosening the head support belt 60. Thus, in the posture assisting tool 1A, the angle of the pillow 65 can be easily finely adjusted by adjusting the length of the head support belt 60, and the head Ma of the patient M can be accurately adjusted to a desired angle. Can be tilted.
