（産業上の利用分野）
この発明は、自動車など乗物のシート姿勢調整装置に関
する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seat posture adjustment device for a vehicle such as an automobile.
（従来の技術）
自動車が左右いずれかの方向に操舵されるときには、シ
ート上の着座者に対し、上記操舵方向と逆の方向に遠心
力が作用することとなる。このため、操舵時には、着座
者は上記遠心力に対抗する体勢をとることが要求される
が、操舵毎にこのような体勢をとることは、操縦性を阻
害することとなって好ましくない。(Prior Art) When an automobile is steered in either the left or right direction, a centrifugal force acts on a person sitting on the seat in a direction opposite to the steering direction. Therefore, during steering, the seated person is required to take a position that resists the centrifugal force, but it is not preferable to take such a position every time the vehicle is steered, as it impedes maneuverability.
そこで、上記遠心力の一部をシート側に支持させて、遠
心力に対抗する際の着座者の負担を軽くするようにした
ものが提案されており、これには、従来、実開昭５８−
９７０３９号公報で示されるものがある。Therefore, a system has been proposed in which a part of the centrifugal force is supported on the seat side to lighten the burden on the seated person when resisting the centrifugal force. −
There is one shown in Publication No. 97039.
これによれば、シートは車体フロア上に左右−対の油圧
シリンダで支持されており、これら各油圧シリンダは車
速検出センサーと、操舵角検出センサーの各検出信号に
より作動させられるようになっている。そして、この作
動により、シートが左右に傾けられて、その着座面が遠
心力に対抗する方向へ傾くよう構成されている。According to this, the seat is supported on the vehicle floor by a pair of left and right hydraulic cylinders, and each of these hydraulic cylinders is activated by detection signals from a vehicle speed detection sensor and a steering angle detection sensor. . By this operation, the seat is tilted left and right, and the seating surface is tilted in a direction that opposes the centrifugal force.
（発明が解決しようとする問題点）
ところで、上記従来構成では、シートは油圧シリンダの
ピストンロッドの突出端に直接的に連結されているが、
単に、このような構成のままにすると、特に、加速前進
時や、減速時には、このシートや着座者の慣性力によっ
てシートが前後に傾くおそれがあり、このときには、シ
ートに対する座り心地が低下するという不都合がある。(Problems to be Solved by the Invention) Incidentally, in the conventional configuration described above, the seat is directly connected to the protruding end of the piston rod of the hydraulic cylinder;
If the configuration is simply left as is, there is a risk that the seat will tilt back and forth due to the inertia of the seat and the occupants, especially when accelerating forward or decelerating, and in this case, the comfort of sitting on the seat will decrease. There is an inconvenience.
そこで、上記シートを、前後方向に延びる枢支軸により
、車体フロア側に左右回動自在に枢支し、このシートが
前後に傾くことを阻止することが考えられる。Therefore, it is possible to prevent the seat from tilting back and forth by pivoting the seat to the vehicle floor side so as to be rotatable left and right by a pivot shaft extending in the front-rear direction.
しかしながら、このようにした場合には、着座者の体格
や好みに合わせてシートを上下に調整しようとしても、
この調整は容易にはできないという不都合がある。However, in this case, even if you try to adjust the seat up or down to suit the physique or preference of the person sitting,
There is a disadvantage that this adjustment cannot be easily made.
（発明の目的）
この発明は、上記のような事情に注目してなされたもの
で、シートの左右傾きの調整に加えて、上下調整もでき

８が設けられている。In FIG. 1, a hydraulic pump 22 is provided for supplying pressure oil to each of the hydraulic cylinders 21.21, and a hydraulic valve 23 is interposed between each of these hydraulic cylinders 21.21 and the hydraulic pump 22. There is. Further, a vehicle speed detection sensor 25 and a steering angle detection sensor 26 are provided, and a calculation means 27 inputs these detection signals to calculate a lateral inertial force (centrifugal force); Control means 2 that controls the hydraulic valve 23 based on the output of the calculation means 27
8 is provided.

くようになっている。While the car is running, move the car, for example, to the right (meaning the direction in the direction of travel of the car; the same applies hereinafter).
Suppose that you steer the vehicle. Then, the centrifugal force is calculated in the calculation means 27 based on the detection signal of the vehicle speed detection sensor 25 which has detected the vehicle speed and the detection signal of the steering angle detection sensor 26 which has detected the steering angle. The hydraulic valve 23 is controlled accordingly. Then, while the left hydraulic cylinder 21 expands, the right hydraulic cylinder 21 contracts, causing the seat 2 to tilt toward the right as shown by the imaginary line in FIG. It is now tilted by the same angle.
即ち、上記したように、自動車を右方に操舵すると、シ

負担が軽減される。That is, as described above, when the automobile is steered to the right, a centrifugal force directed to the left acts on the seat 2 and the seated person 6, as shown by the arrow F in FIG. And at this time,
Since the seat 2 is tilted to the right as described above, the seating surface of the seat 2 on the seat cushion 7 is tilted in a direction that opposes the centrifugal force F acting on the seated person 6. Therefore, a part of this centrifugal force F is supported by the seat cushion 7, and the burden on the seated person 6 who resists this centrifugal force F is reduced accordingly.
また、自動車の走行中に、上記とは逆に自動車を左方に
操舵したときには、上記と同しような作用によりシート
２は左方に向って傾ぎ、このときは、右方に向う遠心力
の一部がシートクツション７により支持されて、着座者
６の負担が軽減される。Additionally, when the car is steered to the left while the car is running, the seat 2 will tilt to the left due to the same action as above, and in this case, centrifugal force directed to the right will cause the seat 2 to tilt to the left. is partially supported by the seat cushion 7, reducing the burden on the seated person 6.
なお、上記のようにシート２を傾けるのは、左右油圧シ
リンダ２１．２１のうちいずれか一方のみを伸縮動作さ
せるようにしてもよい。Incidentally, in order to tilt the seat 2 as described above, only one of the left and right hydraulic cylinders 21 and 21 may be operated to expand and contract.
また、上記左右油圧シリンダ２１．２１を均等に作動さ
せれば、シート２の左右各側部の昇降寸法が同じとなり
、これにより、シート２の上下位置が着座者６の体格や
好みに合わせて無段階に調整できる。Furthermore, if the left and right hydraulic cylinders 21 and 21 are operated evenly, the vertical dimensions of the left and right sides of the seat 2 will be the same, so that the vertical position of the seat 2 can be adjusted according to the physique and preferences of the seated person 6. Can be adjusted steplessly.
上記の場合、内回動アーム１１と外回動アーム１２とは
前記したように側面視でほぼＸ字状をなしているため、
この両者を相対回動させたときには、シート２は上下に
ほぼ平行移動し、前後に傾くことが防止される。また、
各外回動アーム１２の前下端はレール１５に枢支されて
いるため、このシート２は前後に移動することなく、は
ぼ垂直に昇降することとなる。In the above case, since the inner rotating arm 11 and the outer rotating arm 12 are approximately X-shaped in side view as described above,
When these two are rotated relative to each other, the seat 2 is vertically moved substantially in parallel, and is prevented from tilting back and forth. Also,
Since the lower front end of each outer rotating arm 12 is pivotally supported by the rail 15, the seat 2 does not move back and forth, but rises and falls almost vertically.
なお、以上は図示の例によるが、各内回動アム１１の後

こととなる。(Effects of the Invention) According to the present invention, a pair of left and right support frames for supporting the seat are provided on the vehicle body floor, and a pair of rotation frames that intersect in a substantially X-shape when viewed from the side are pivoted to each other at the intersection. Each support frame is composed of movable arms, and the lower end of each rotary arm is connected to the vehicle floor side, while the seat is connected to the upper end, and an actuator is provided to rotate each pair of rotary arms relative to each other. Therefore, when the actuator is activated, the pair of rotating arms rotates relative to each other.
Each upper end side moves up and down, and the sheet moves up and down accordingly.

着座者の負担が軽減される。In the above case, if the left and right actuators are actuated unevenly, the lift dimensions of the left and right portions of the seat will be different, and the left and right inclination of the seat will be adjusted. Therefore, the seating surface of the seat can be tilted in a direction that opposes the centrifugal force during steering, and in this way, the burden on the seated person in resisting the centrifugal force is reduced.
一方、同上左右アクチュエータを均等に作動させれば、
シートの左右各個部の昇降寸法が同じとなることから、
これによりシートの上下位置を調整できることとなる。On the other hand, if the left and right actuators are operated equally,
Since the lifting and lowering dimensions of the left and right parts of the seat are the same,
This allows the vertical position of the seat to be adjusted.
しかも、上記両回動アームは前記したように側面視でほ

平行移動することとなる。Moreover, as described above, both of the rotating arms have an almost X-shape when viewed from the side, so when they are rotated relative to each other, the seats connected to their respective upper ends move vertically in almost parallel. I will do it.
従って、上記各調整時や、その調整の前後においてもシ
ートが前後に傾くことは防止され、良好な座り心地が確
保されて有益である。Therefore, the seat is prevented from tilting back and forth during each of the above-mentioned adjustments and before and after each adjustment, which is beneficial because a good sitting comfort is ensured.
