The rotational force will be transmitted only to the gear (28). Therefore, only the front lead screw (16) is rotated and the front attachment support mechanism (2) is moved up and down, which causes the seat cushion to move forward with the rear attachment support mechanism (3) as the fulcrum. It moves upwards or downwards and the front part becomes a high or low inclination state.

By locking through the 2), only the rear lead screw (17) is rotated and the rear mounting support mechanism (3) is moved up and down, and the seat cushion is the front mounting support mechanism.
The rear part moves upward or downward with (2) as a fulcrum part, and the rear part becomes a high or low inclined state.
このようにしてシートクツシヨンの傾斜が調節される。In this way, the inclination of the seat cushion is adjusted.
