Abstract

PURPOSE:To permit smooth operation with a thin operation mechanism by allowing a movement transmission link to be connected to a driving link by using a movement transmission link equipped with a cam plate having a cam groove and a ball fitted into said cam groove, as a front-seat adjuster for a car. CONSTITUTION:When an operation handle 29 is turned in the direction of arrow A, a cam plate 25 is turned in the direction of arrow B through the engagement of a sector gear 27 and a pinion 22. Then, a movement transmission link 20 is shifted in the direction of arrow C because of the relation between a cam groove 30 in which the distance from the center of turn gradually increases and a ball 31 fitted into said cam groove and the regulation of the ball 31 in the direction of movement by a guide hole 21. Therefore, a driving link 34 is pulled, and then a turning shaft 4, link 5, interlocking link 8, and a link 7 are shifted simultaneously in the direction of arrow D, and a seat frame 13, i.e., seat is raised. When the operation handle 29 is revolved reversely, the seat is lowered.

り、操作性が悪くなったりすることがあった。The seat vertical adjustment device supports a seat frame movably through a link mechanism or the like with respect to a lower bracket fixed to the vehicle floor side, and moves the seat frame up and down by some operating mechanism. It has a basic configuration. Although various operating mechanisms have been proposed, all conventional devices use a gear mechanism or a screw mechanism to transmit the rotational force applied to the operating handle side to a link mechanism or other components. There was also the problem of play and looseness, and the mechanism became complicated and the cost increased. In addition, the operating mechanism is usually located on the side of the seat, but conventional products are structurally thick, that is, the dimension in the lateral direction of the seat is large, resulting in unreasonable mechanical configurations and poor operability. I had something to do.

0, a pole 31 is fitted in a relatively slidable manner. The pawl 31 is attached to one end of the N-motion transmission link 20 by a pin 32 so as to be relatively rotatable, and the pin 32 is fitted into the guide hole 21 . The scales of the motion transmission link 20 are attached by pins 35 to a drive link 34 fixed to the rotation shaft 4 by welding or other fixing means. The motion transmission link 20 in such a connected state is 1. The position is set so as to pass near the center of rotation of the cam plate 25, and the guide hole ? 1 faces in the radial direction of the cam plate 25 and restricts the movement of the pawl 31 at one end of the motion transmission link 20 in the same direction. Reference numeral 36 indicates a leaf spring that presses the cam plate 25 in the axial direction to stop it from rotating.

ある。Therefore, with the above-described configuration, when the operating handle 29 is rotated in the direction of the arrow in the state shown in FIG. 2, for example,
The cam plate 25 rotates in the direction of arrow B due to the engagement between the sector gear 27 and the pinion 22. Then, due to the relationship between the cam groove 30 whose distance from the center of rotation gradually changes (increases) and the pawl 31 fitted therein, and the regulation of the direction of movement of Bore 1 < 31 by the guide hole 21, the motion is transmitted. The link 20 moves in the direction of arrow C, and as a result, the drive link 34 is pulled, causing the rotation shaft 4, link 5, interlocking link 8, and link 7 to move (rotate) all at once in the direction of the arrow, and the seat frame 13, that is, the seat rises. It is clear that if the operating handle 29 is reversed, the seat will be lowered.

は回転せずブレーキ作用が得られる。The following braking action is applied to the descending force applied from the seat and side. In other words, the descending force from the seat side is 5.
Contrary to the above explanation, an attempt is made to move the motion transmission link 20 in the direction C' opposite to the arrow C, and this moving force is applied to the ball 3.
1 to the cam groove 30 wall. However, since the motion transmission link 20 passes near the center of rotation of the cam plate 25, the force exerted on the cam groove 30 has almost no component in the circumferential direction of the cam plate 25.
does not rotate and provides braking action.

ほぼ同様の作用が得られる。As described above, it is preferable that the motion transmission link 20 moves on a line passing through the center of rotation of the cam plate 25, but it is possible to change the direction of the motion transmission link 20 within a range where a braking action can be obtained. In the embodiment, the motion transmission link 20 is pivotally connected to the specially provided drive link 34, but the links 5 and 7 or the interlocking link 8 may be used as the drive link.
Even if the motion transmission link 20 is pivotally connected to one of these, substantially the same effect as described above can be obtained.

逆に運動伝達リンク２０の運動方向をカム板２５の直径
方向に厳密に限定して案内してもよい。Conversely, the movement direction of the motion transmission link 20 may be strictly limited to the diametrical direction of the cam plate 25 for guidance.

ことができる。Furthermore, in the above embodiment, the rotation of the operating handle 29 is increased in speed and transmitted to the cam plate 25 via the sector gear 27 and pinion 22, but this is because the rotation angle of the cam plate 25 is set to about 300 degrees. The operating angle of the operating handle 29 is 70
~90 degrees, and the speed increasing ratio is the cam plate 2.
5 and the operating angle of the operating handle 29 can be changed as appropriate.

用を得ることができる。As described above, the seat vertical adjustment device according to the present invention has a basic operating mechanism composed of a cam plate having a cam groove and a motion transmission link having a ball fitted into the cam groove at one end, so that the seat vertical adjustment device according to the present invention is easy to operate. Since the rotation of the cam plate is transmitted to the motion transmission link via the cam groove and the ball, smooth operation without backlash can be obtained by simply setting a small clearance between the cam groove and the ball. In addition, since the downward force applied from the seat side is supported by the braking action generated by the friction between the ball and the cam groove, no special braking device is required. maximum braking action can be obtained.
