As a method of this rotational biasing, the cam (16) is shaped such that its center of gravity is always located on the rear side with respect to the center of rotation (fifth position).
(See the drawing), and a tension spring is attached to the cam (16) so that the cam (16) is pivotally biased rearward. The surface of this groove cam (16) is made rough so that the engagement pin (1
The friction resistance of the washer (20) that fits in (7) is large.

望ましい。A pad receiving spring (21) is installed on the upper surface side of the cushion frame (11), and a spring (22) is stretched over the movable frame (12) separately from the spring (21). The upper surface from the frame (11) to the movable frame (12), that is, the butts and the receiving springs (21) and (2
A sheet pad is placed on the upper surface of 2) and covered with a skin (23) to form a sheet cushion (2). In this case, it is desirable to divide the seat pad into the cushion frame (11) side and the movable frame (12) side, or to form the bent groove (2b) between them.
次に以上の構成されるシートクツシヨンの動作について
説明する。Next, the operation of the above-described sheet cushion will be described.
先ずハンドル(19)によりシフト(18)を回動すると溝カム

れ座面が高く変位される。First, when the shift (18) is turned by the handle (19), the groove cam
(16) is also rotated integrally, and this rotation is rotated in the direction of arrow a in FIG. 3, that is, when it is rotated in the small diameter direction of the slot (16a) of the cam (16), the large diameter side of the slot (16a) is moved. The engagement pin (17) that is implanted in the movable frame (12) is pressed, that is, the engagement pin (17) is cam (16).
The movable frame (12) is pivoted upward about the pivot pin (14) of the pivotal portion, and the front portion (2a) of the seat cushion (2) is launched. And the seat surface is displaced high.
また、カム(16)を矢印ａと反対方向に回転させると係合

シートクツシヨン(2)の前部(2a)は低位置に変位される
ことになる。Further, when the cam (16) is rotated in the direction opposite to the arrow a, the engagement pin (17) corresponds to the small diameter portion of the slot (16a). Therefore, the rotation center of the cam (16) and the engagement pin ( The interval of 17) is narrowed, the movable frame (12) is rotated downward, and the front part (2a) of the seat cushion (2) is displaced to a low position.

られることになる。In this state, when downward or upward pressing force is applied to the movable frame (12), the engagement pin (17) of the cam (16) causes the groove (16
Since the positive cam structure is in sliding contact with both side edges of a), the engagement pin (17) pushes the cam (16) downward or upward, and the engagement pin (17) rotates the cam (16). Since the movable frame (12) is engaged with the groove hole (16a) on the pivoting side of the movable frame (12) with respect to the vertical line 1 passing through the center, when downward pressure is applied to the movable frame (12), the cam (16) moves backward. I.e., the movable frame (12) is rotated in the direction toward the pivotal part, but the slot (16a) is
Since the cam (16) is formed with a small diameter rearward with respect to the center of rotation of (16), the large diameter part of the slot (16a) will bite into the engagement pin (17) when the cam (16) is rotated rearward. The cam (16) is strongly pinched by the shaft (18) and the engagement pin (17), so that the rotation of the cam (16) is prevented. Therefore, the movable frame (12) is prevented from pivoting downward or upward, and is retained and retained at a desired pivotal position.
The front part (2a) of (2) is set and held at a desired height. It should be noted that the cam (16) is always formed so that its center of gravity is always located rearward of the center of rotation, or a spring is stretched behind the cam (16) so that the cam (16) is always rotated rearward. If it is biased to move, the cam (16) is prevented from unnecessary rotation due to vibration when the movable frame (12) is lightly loaded and the movable frame is prevented.
The rotation of (12), especially unnecessary rotation in the fall direction, is prevented. Further, the frictional contact between the cam (16) and the washer (20) fitted to the engagement pin (17) also suppresses the rotation of the cam (16).

位置して植設することになる。Although the seat cysupport device according to the present invention has been described above, this device can also be applied as a height or front / rear position adjustment locking device for a cysupport portion, a headrest, or the like. For example, in the case of being applied to an adjusting locking device for tilting or fore and aft positions of a headless, the adjusting locking mechanism (15) is arranged between the headless stay and the headless body panel. That is, the headless body panel is pivotally attached to the headless stay rotatably in the front-rear direction, the cam (16) is pivotally attached to the headless stay, and the pin which engages with the groove hole (16a) of the cam (16) ( 1
7) is planted on the panel side of the headless body. in this case,
The engagement pin (17) should be installed at the cam (16) position as in the above example.
Will be planted by being located between the center of rotation and the pivotal attachment of the headless body panel.
