The contour seat 7 can be moved up and down with respect to the base 3, the backrest 6 can be tilted with respect to the contour seat 7, and the leg rest 9 can be tilted with respect to the contour seat 7. .

(First embodiment)
2 is a front view of the headrest, FIG. 3 is a cross-sectional view taken along the line III-III of FIG. 2, and FIG. 4 is a diagram for explaining a usage state of the headrest.
As shown in FIG. 2, the headrest 5 is installed on the backrest 6 via the support column 20, and can be raised and lowered manually with respect to the backrest 6, for example.

  The headrest 5 also has a front member 21 that supports the central position of the patient's head and neck. The lower portion 21a of the front member 21 is recessed upward at a position corresponding to the back side of the neck of the patient, and the planar heater 22 is provided at this position. The planar heater 22 corresponds to the heater device of the present invention. Further, the “back side of the neck” of the present invention corresponds to the vicinity of the boundary between the occipital region and the neck, specifically, near the hairline, and extends from the back of the right ear to the back of the left ear. The area (also called the brainstem zone).

  More specifically, as shown in FIG. 3, the headrest 5 includes a front member 21 and a frame 23 that covers the rear of the front member 21, and the frame 23 is a rear surface portion located on the back side of the front member 21. 24 and side portions 25 that are respectively arranged on the left and right sides of the back surface portion 24 and that can face the lateral positions of the head and neck. The column 20 is fixed to the back surface of the frame 23, but the back surface of the frame 23 can be rotatably supported.

The front member 21 is formed of, for example, a flexible synthetic leather (may be cloth), and the left and right ends thereof are fixed to the tips of the side portions 25. The back side of the front member 21 is covered with, for example, a mesh material, and the planar heater 22 is disposed between the synthetic leather and the mesh material at the position of the lower portion 21a of the front member 21.
The planar heater 22 has, for example, a heating element (a nichrome wire or a nichrome foil) sandwiched between silicon sheet members, and is thinly formed to have flexibility and flexibility. If the planar heater 22 is used in this way, it can be easily mounted on the headrest 5.

  Then, when the patient sits down on the contour sheet 7 and puts the head and neck on the headrest 5, the front member 21 bends toward the back portion 24, and the front member 21 wraps the head and neck, and the planar heater 22 covers the patient. Warm the back of the neck. As a result, thermal stimulation is given to the brainstem zone, so that muscle tension can be relieved. Therefore, the patient under treatment can be relaxed.

Also, when the muscle tension is relieved, as shown in FIG. 4, the mouth becomes easier to open, and it becomes difficult to feel pain or stress even if the mouth is kept open. Therefore, it is possible to easily maintain the open state of the mouth and smoothly proceed with the treatment.
Furthermore, since the front member 21 is pushed and bent by the neck of the patient, the planar heater 22 can be fitted to the brainstem zone.

(Second embodiment)
FIG. 5: is sectional drawing of the headrest of 2nd Embodiment. Although the frame 23 of the first embodiment has a curved integrated structure, it may have a split structure.
Specifically, as in the first embodiment, the planar heater 22 is arranged on the front member 21 shown in FIG. 5 (A), and the frame 23 has a rear surface portion 24 and side portions 25. However, the back surface portion 24 and the side portion 25 are configured as separate bodies.

A self-closing spring hinge 31 is provided at the boundary position between the back surface portion 24 and the side portion 25. The self-closing spring hinge 31 urges the tip of the side portion 25 to approach the central position of the front member 21.
Further, as shown in FIG. 5 (A), a cushion member 30 made of urethane, for example, is housed in the space surrounded by the front member 21, the back portion 24, and the side portions 25. The cushion member 30 has a repulsive force that can counter the biasing force of the self-closing spring hinge 31.

As a result, as shown in FIG. 5A, until the front member 21 receives the load of the head and neck, the side portions 25 are separated from the central position of the front member 21 by the repulsive force of the cushion member 30 ( It is open toward the outside).
Then, when the front member 21 receives the load of the head and neck, the front member 21 is deformed rearward and the tip of the side portion 25 is pulled, and the urging force of the self-closing spring hinge 31 is increased. 5B, the side portion 25 closes in the direction (inward) toward the central position of the front member 21, as shown in FIG. 5 (B).

Thus, if the headrest 5 is configured to be pushed and closed by the patient's neck, the planar heater 22 can be fitted more to the brainstem zone.
In addition, in FIG. 5, the example in which the headrest 5 is configured to be pushed and closed by the neck of the patient has been described. However, the invention is not limited to this example. For example, until the front member 21 receives the load of the head and neck, the side member 25 is urged by the self-closing spring hinge 31 and the central position of the front member 21 is stored until the cushion member 30 having a small repulsive force is stored. It closes in the direction toward (inside). Then, when the front member 21 receives the load of the head and neck, the side portion 25 resists the biasing force of the self-closing spring hinge 31 toward the direction (outside) away from the central position of the front member 21. It may be opened.

(Third Embodiment)
FIG. 6 is a diagram illustrating a headrest of the third embodiment.
In the first and second embodiments, the example in which the pad is one has been described, but the present invention may be a double pad type headrest 5.
Specifically, as shown in FIG. 6, it has a pair of pads 42 formed in a circular shape when viewed from the front, and each has the above-described planar heater built therein.

  The back surface of the putt 42 is supported by the putt support portion 41, and is arranged at a predetermined distance so that the putt 42 can push the back of the right ear or the back of the left ear. The pad support portion 41 is rotatably provided on the rotating arm portion 40, and the rotating arm portion 40 is also rotatably provided on the support column 20. Also in this case, the brainstem zone can be given a thermal stimulus to relieve muscle tension.
