した点である。The toothed portion of the toothed plate 9 is adapted to engage and hold the pawl pin 8. There is a small hole near the outer edge of the toothed plate 9, and links 10 are attached to both sides by pins 11, and the other end of the link 10 is rotatably attached to the upper frame 2 by a support pin 12. An arm 15 shown in FIG. 4 is fixed to the other end of the connecting rod 13 in the left lower frame 1 (FIG. 1) with a pin 16, and a link 17 is rotated with a pin 18 at the end of the arm 15. The other end of the link 17 is rotatably mounted with a support pin 19 within a side bracket 24 fixed to the side of the upper left frame 2 in FIG. In the present invention, the above-mentioned adjustment mechanism is provided at the front (upper part of the figure) and the rear of the seat as shown in FIG. The end is not the side wall of the lower frame 1,
This is the point where it is fixed to the bracket 25 welded to the side wall of the lower frame 1.

第７図と第１，２図とにより説明する。As shown in FIGS. 5 to 7, the rear connecting rod 13 and the support pin 12 at the upper end of the link 10 on the right side (front of the seat) are connected to the lower surface of the upper frame 2 by connecting rods 21 for reinforcement and to prevent rattling. Concatenated. Next, the operation of the apparatus of the present invention will be explained with reference to FIGS. 5 to 7 and FIGS. 1 and 2.
第５図及至第７図は右側が座席の前部で、第５図で前方

止めピン８は歯形板９の歯形との係合が外れ、座席を載
置した上部フレームは連結ロッド１３に止着したコイル
ばね２３の弾性により第５図に示すように座席後部が上
るので、体重を乗せて適宜位置でハンドル３を離すと歯
止めピン８は歯形板９の歯部と係合し保持される。In Figures 5 to 7, the right side is the front part of the seat, and in Figure 5, the front handle 3 remains as it is, and the rear handle 3 (first,
2) is raised upward, the pawl pin 8 is disengaged from the tooth profile of the tooth profile plate 9 by the arm male link 6, and the upper frame on which the seat is mounted is moved by the elasticity of the coil spring 23 fixed to the connecting rod 13. As a result, the rear of the seat rises as shown in FIG. 5, and when the user puts his/her weight on the seat and releases the handle 3 at an appropriate position, the pawl pin 8 engages with the teeth of the toothed plate 9 and is held.
第６図は上記と反対に座席の前部を上げたもので、後部
はそのままとし、前部のハンドル３を上記と同様にして
座席を載置する上部フレーム３を上げた例を示す。FIG. 6 shows an example in which the front part of the seat is raised, contrary to the above, the rear part is left as is, the front handle 3 is set in the same manner as above, and the upper frame 3 on which the seat is placed is raised.
第７図は座席の全体を上げる例で、ハンドル３以下を前
後部共上記と同様に操作して行う。FIG. 7 shows an example in which the entire seat is raised by operating the handlebars 3 and below in the same manner as above.
図は高さの最大を示しているが、高さを調整するには歯
止めピン８と歯形板９との係合を外したまま、体重をの
せて適宜位置でハンドル３を離し、歯止めピン８を歯形
板９に係合させればよい。従来の車両用座席では、運転
車の体格によりアイポイントが変つた場合、運転車は座
布団などを尻の下に敷いて対処していたが、このように
アイポイントを高くする場合はよいが、低くすることは
できなかつた。The figure shows the maximum height, but to adjust the height, disengage the pawl pin 8 and the toothed plate 9, put your weight on it, and release the handle 3 at the appropriate position. What is necessary is to engage the toothed plate 9 with the toothed plate 9. In conventional vehicle seats, if the eye point changes depending on the physique of the driver, the driver would put a cushion or something under his or her buttocks to deal with it. It couldn't be lowered.
本発明装置は体格差によるアイポイントのずれを修正で
きることはもちろん、運転者の好みによる前傾姿勢、後
傾姿勢も調整できる。The device of the present invention can not only correct the deviation of the eye point due to differences in body size, but also adjust forward and backward leaning postures according to the driver's preference.
このように、運転者の体格、好みによる姿勢を得ること
により、無理な姿勢からくる被労をなくすことができる
。In this way, by obtaining a posture according to the driver's physique and preference, it is possible to eliminate the strain caused by an unreasonable posture.
なお、トラックにおいては、荷台に積載した時と空荷に
した時とリーフスプリングの撓みが異り、座席下の床面
の傾斜が変るので、このため座角調整は必要である。In addition, in a truck, the deflection of the leaf springs is different when the truck is loaded and when the truck is empty, and the slope of the floor surface under the seat changes, so it is necessary to adjust the seating angle.
