Claims

[Scope of Claim for Utility Model Registration] 1. In a medical treatment table in which the back plate is movable relative to the seat, a seat base 1 and a support shaft 1 relative to the base 1 are provided.
-02 as a center, the back plate 2 is supported on the support shaft 102 and the side of the base 1;
a pair of left and right parallel link frames 3 that interlock with each other, a seat 4 that is horizontally supported and held by the parallel link mechanisms 3 and is located above the base 1, the back plate 2 and the parallel link mechanisms 3. The power of the drive mechanism 5 moves the seat 4 forward when the back plate 2 is in the upright state, and moves the seat 4 forward when the back board 2 is in the collapsed state. 2. A medical treatment table characterized in that the parallel link mechanism 3 is supported by the support shaft 102 and a pin 11 fixed to the side of the seat base 1. The first parallel link 31, 32 is supported by the pin 12 fixed to the side of the base 1 horizontally in front of the bin 11 and the first parallel link 31, 32.
．． The seat sheet 4 is horizontally supported and held at the upper end of the second parallel link 3C35, and the seat sheet 4 whose back is in contact with the back plate 2. Claims for registration of a utility model in which an imaginary line segment l connecting the imaginary rotation center O of the lower back of the patient P above and the axis of the support shaft 102 is substantially parallel to and has the same length as the second parallel link 34° 35. The treatment table described in paragraph 1.
