Is pivotally supported. The drive source is not limited to a hydraulic cylinder, and may be a motor and a screw rod, or an air cylinder.

  Reference numeral 9 denotes a sheath whose one end is pivotally supported by the mounting bracket 1c, and a sliding plate 10 is slidably fitted into the sheath 9. 11 is a backrest, and a reverse plate-shaped fixing plate 11b is fixed to the backrest substrate 11a of the backrest 11, and a fixed shaft 11c is projected from a bent portion of the fixing plate 11b. The other end of the support plate 12 having one end fixed to the fixing pin 2a is rotatably supported on the fixed shaft 11c. Therefore, the backrest substrate 11 a can rotate with respect to the support plate 12. Further, the tip of the sliding plate 10 is pivotally supported at the tip of the bent piece portion 11b1 of the fixed plate 11b.

  Reference numeral 13 denotes an adjustment rod having one end connected to a fixed plate 14 fixed to the fixed shaft 11c, and the tip side is inserted into a pipe 15 fixed to the back side of the backrest substrate 11a. Reference numeral 16 denotes a rotating par rotatably supported on the back side of the backrest substrate 11a, one end of which protrudes from the side surface of the backrest 11, and a handle 16a is attached to the protruding portion. An eccentric polygonal piece 17 shown in FIG. 7 is attached to a position of the rotating bar 16 facing the upper end of the challenge rod 13.

  In the case of the quadrangle 17 as shown in FIG. 7a, the tip of the adjustment rod 13 comes into contact with two surfaces in the case of FIG. 7a, and the tip of the adjustment rod 13 comes into contact with three surfaces in the case of FIG. Although not shown, the tip of the adjustment rod 13 abuts steplessly by using an elliptical shape. As a result, the backrest 11 can finely adjust the overturning angle as will be described in detail later.

Then, when the hook member 18 returns the handle to the initial position (position shown in FIGS. 1 to 5), the position facing the tip of the adjustment rod 13 is the surface of the piece 17 whose interval is the longest than the eccentric shaft. It is being fixed to the rotation par 16 so that it may become. Reference numeral 20 denotes a cushion air vent hole opened in the backrest substrate 11a.

  Next, the operation will be described based on the above-described configuration. In the introduction state of the patient shown in FIGS. 1 and 2, the ram of the hydraulic cylinder 7 is in a state of being housed in the cylinder. The seat part 4 is located in the front, and the backrest 11 is in an upright state.

  In this state, when the person to be treated is seated on the seat 4 and shampooing is performed, if an operation switch for performing shampoo (not shown) is operated, oil is supplied into the hydraulic cylinder 7 and the rod starts to extend. When the rod is extended, one hanging arm 2 of the parallel link is pushed to the left in the figure through the connecting plate 8, so that the seat 4 and the backrest 11 are kept in the left direction (shampoo ball B side). ) And move up.

  During this movement, the backrest 11 is subjected to a counterclockwise load due to the weight of the backrest 11 and the leaning weight against the backrest of the person to be treated, so that the sliding plate 10 is housed in the sheath 9. Being prostrate while maintaining. Further, when the backrest 11 starts to fall down, the adjustment base 13 whose one end is pivotally supported by the fixed plate 14 is moved by the deviation between the fixed shaft 11c, which is the rotation axis of the backrest base 11a, and the pipe 15. When lying down to a predetermined angle, the adjustment rod 13 moves in the pipe 15 and the tip comes into contact with the piece 17. Therefore, the prone position of the backrest 11 stops in this state (see FIG. 3).

  However, even if the backrest 11 stops lying down, the ram is projected by the hydraulic cylinder 7, and the parallel link continues to rise and move to the right. In this state, since the sliding plate 10 moves in the direction of being pulled out with respect to the sheath 9, further movement of the seat portion 4 and the backrest 11 obliquely upward is performed. Then, when the practitioner determines that the position of the practitioner with respect to the shampoo ball B is good and turns off the switch, all the operations are finished, and the back of the neck of the practitioner matches the neck receiver B1 of the shampoo ball B. (See FIG. 4).

  In this state, when the back portion of the neck of the patient is higher than the neck receiving portion B1, the handle 16a is rotated against the spring force of the spring 19, and the distance from the center line of the rotating bar 16 is short. By rotating the piece 17 so that the surface faces the front end of the adjustment rod 13, the backrest 11 further falls down, so that the back portion of the neck and the neck receiver B1 fit. Note that by changing the shape of the piece 17 as shown in FIG. 7, the fine adjustment of the backrest 11 can be changed in a plurality of steps or in a stepless manner (see FIGS. 5 and 6).

  Further, when the sitting height of the patient is high and the sleeping angle of the backrest 11 is high by the handle 16a, the parallel link is made in the direction opposite to that described above while operating the return switch to drain the oil in the cylinder 7. Since the backrest 11 moves in a direction away from the shampoo ball B together with the seat portion 4, the back of the neck of the subject can be matched with the neck receiver B1 by performing this adjustment.

  Next, the operation when the shampoo of the patient is completed will be described. By operating the return switch, the ram of the hydraulic cylinder 7 is accommodated in the cylinder, so the parallel link is opposite to the above. The seat 4 moves while descending in the right direction, and the backrest 11 rises to the initial state.

  Further, in the state of returning to the initial position, the adjusting rod 13 is lowered and separated from the piece 17, so that the handle 16 a returns to the initial position by the spring force of the spring 19 when the subject is separated from the seat 4. Therefore, the piece 17 is also returned to the initial position.
