DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic structural view of an essential part for explaining an embodiment of a dental treatment chair 1 according to the present invention, in which 11 is a contour seat, 12 is a backrest, and 13 is a backrest.
FIG. 1 (A) is a view when the dental treatment chair 1 according to the present invention is adjusted for an adult (L = long), and FIG. 1 (B) is adjusted for a child (L = short). FIG. Thus, in the present invention, the contour sheet 11 is formed of a flexible member, and is configured to hang down without support.

For this purpose, support members 14 and 15 for supporting the contour sheet 11 are provided on the lower main body side (the main body is not shown) of the contour sheet 11.
4 supports the rear end side (the side on which the patient sits) of the contour sheet 11, and the support member 15 supports the contour sheet 11.
It supports the tip side (toe side).

The contour seat support member 14 on the backrest 12 side (the side on which the patient sits) includes a movable support member 16 that extends and contracts forward (toe side) of the contour seat 11, FIG. 1A shows the supporting member 16.
As shown in the figure, when the user moves in the direction of arrow A, the bending point a of the contour sheet 11 extends forward, the distance L from the backrest 12 increases, and when a tall person (adult) sits, It can be adjusted so that the inflection point a comes below the knee. FIG. 1B shows the movable support member 16.
Is moved in the direction of arrow B. In this case, the bending point a of the contour sheet 11 retreats toward the backrest 12, the distance L from the backrest 12 is reduced, and a person (child) ) Can be adjusted so that the inflection point a is below the patient's knee when sitting.

In FIG. 1, reference numeral 17 denotes a slit provided in the contour sheet support member 14, and reference numeral 18 denotes a movable support member 1.
6, the handle 18 is provided extending from the slit 17, and the movable support member 16 is moved by holding the handle 18 and moving in the direction of arrow A or B. It can be extended to a desired position, whereby the bending point a can be adjusted to any desired position and adjusted to the height of the patient, in other words, to a position that fits the feet of the patient. . Although the figure shows an example in which the movable support member 16 is moved manually, the movable support member 16 may be adjusted using any desired power source such as an electric type, a hydraulic type, and a pneumatic type. Is also possible.

[0010]

As is apparent from the above description, according to the present invention, the contour sheet is made of a flexible member, and the length from the backrest to the bending position can be arbitrarily changed. A single dental treatment chair can be configured to fit from adult to child and even to each patient's body type (foot length), making the treatment chair suitable for each patient Can perform dental treatment.
