<p><P>PROBLEM TO BE SOLVED: To reduce time required for a chair for dental treatment to reach a gargling position by changing a moving speed of the chair for dental treatment from a height position (the amount of pulling out) of a headrest pulled out upward from a backrest when the height of the chair for dental treatment is moved from a treatment position to the gargling position. <P>SOLUTION: A dental treatment unit includes the chair 1 for dental treatment which has the headrest 1a mounted on the backrest 1b in a manner to make vertical movements (S) and enables adjustments (T) of the height position of a contour seat 1c and a spittoon bowl 4 which is installed to erect on the side of the chair 1 and has a fixed height. The chair 1 has a sensor (not shown in the figure) for detecting the height position of the headrest 1a from the backrest 1b and changes the moving speed to move the contour seat 1c to the height for the gargling position depending on the magnitude of the value detected by the sensor. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
