いる。In these figures, the seat cushion 1 can be adjusted in position forward and backward by a slide 5 on a floor 9, a seat back 2 has an upper back portion 6 and a lower back portion 7, and a lower back portion 7 is provided at a rear portion of the seat cushion 1. The lower ends are joined by hinge pins 4,
The upper end of the lower back portion 6 is joined to the lower end by a hinge pin 3. The upper back portion 6 is connected to a vehicle body-side back panel 8 by an adjuster (guide hole) so as to be slidable in the vertical direction.

ものである。[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a seat cushion whose position can be adjusted in the vehicle front-rear direction by a first slider, and a lower end of which is a rear end of the seat cushion. A lower back portion of the seat back which is pin-connected and is connected to the vehicle body via a second slider, and a lower back portion which is located above the lower back portion and which is connected to the lower back portion by a spring and which is connected to the vehicle body through a third slider. The upper back and the back of the seat back are joined together.

合されているためガタ異音の発生が少くなる。(Function) When the seat cushion moves forward by the first slider, the lower back lower end also moves forward. In that case, the lower back is second
Since it is guided almost vertically by the slider, it tilts diagonally. As the lower back moves, the upper back is pulled by the spring connected to the lower back, so that the lower back follows the lower back while being guided by the third slider. Since the lower back portion is not pin-connected to the upper back portion but is connected to the vehicle body by the second slider, the rattling noise is reduced.

（実施例） 以下、この考案の一実施例を第１〜第４図により説明す

後動できる。The seat cushion 1 can be moved in the front-rear direction of the vehicle body by an upwardly concave arc-shaped first slider 11 and its position can be adjusted. The first slider 11 is an upper rail 13
And a lower rail 15, the upper rail 13 is fixed to the seat cushion frame 17, and the lower rail 15 is attached to the floor 9. As shown in FIG. 2, rack teeth are engraved on the edge of the upper rail 13, and the pinion of the motor 19 fixed to the floor 9 and the rotation of the meshing motor 19 can move back and forth as shown by the arrow.

なっている。The seat back 2 is divided into an upper back portion 6 and a lower back portion 7 together with the frame. The lower back portion 7 has a lower end of a frame 21 rotatably coupled to a rear end of a seat cushion frame 17 by a hinge pin 4, and a guide pin 23 formed in a side portion of the frame 21 for fixing a second body. Slider 25
It is designed so that it can be slid into the arc-shaped elongated hole 27 in a slanting downward curved shape. Further, the upper back 6 and the lower back 7 are formed with a frame and a cushion separately from each other. However, when the upper back 6 and the lower back 7 are arranged in a vehicle as shown in FIG. The two frames 29 and 21 are communicated with each other. Spring 3
Reference numeral 7 has a structure in which the corresponding cushion portions are notched so that both ends can be hooked to the brackets 39 and 41 of both frames in the seat set state. A guide pin 31 formed in a side portion of the frame 29 of the upper back portion 6 is fitted in an arcuate elongated hole 35 of a third slider 33 fixed to the vehicle body so that it can slide substantially vertically. .

により斜めに傾いた状態となる（第４図）。Next, the operation of the above embodiment will be described. When the occupant is in the state shown in FIG. 3 and wants to relax from now on, when a button switch (not shown) is pressed, the motor 19 rotates normally. Then, the upper rail 13 of the first slider 11 moves forward (second
), The frame 17, and thus the seat cushion 1 advances. Since the lower end of the frame 21 is joined to the rear end of the seat cushion frame 17 by the pin 4, the lower end of the seat back lower back portion 7 advances, and at the same time, the circular arc long hole 27 of the second slider 25 is inserted into the guide pin 23. It slides into an inclined state (Fig. 4).

長穴３５をガイドピン３１が摺動して案内されることに
より、結局、下背部６に追従して移行することになる。
このためそれらの間に隙間を生じない。Since the upper back portion 6 is pulled by the coil spring 37 by the downward movement of the lower back portion 7, the guide pin 31 slides in the elongated hole 35 of the third slider 33 to guide the lower back portion. It will follow 6 and shift.
Therefore, no gap is created between them.

このようにして、乗員は安楽なリラックス姿勢をとるこ
とができる。In this way, the occupant can take a comfortable and relaxed posture.

ため、その部分でガタ異音が発生する事はない。又、
上、下背部共、スライダで車体に結合されているため、
ガタが少くなり商品力が向上する。尚、上背部は下背部

い。Since the upper back and the lower back are not pin-coupled at all, no rattling noise is generated at that portion. or,
Since both the upper and lower back parts are connected to the vehicle body with sliders,
There is less backlash and the product strength improves. Since the upper back part is divided from the lower back part, it is easy to set it on the vehicle body.

シートを元に戻す場合は、前述の逆の操作をすればよ
い。この場合、上背部６は下背部７の上端で押上げられ

内されて上方移動するものである。To return the sheet to its original position, the reverse operation described above may be performed. In this case, the upper back portion 6 is pushed up by the upper end of the lower back portion 7, and at that time, the upper back portion 6 is guided by the third slider 33 and moves upward.

前記実施例ではシートクッションスライダをモータ駆動
するようにしたが、本案は乗員の力で操作する通常のマ
ニアル式のスライダでも成立することは勿論である。Although the seat cushion slider is driven by a motor in the above-mentioned embodiment, the present invention can also be applied to a normal manual slider operated by the force of an occupant.
