本考案は例えば自動車の如き走行体時にトレー
ラを牽引するトラクタ或いはトレーラヘツドの運
転台等の座席に用いて好適な座席支持装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat support device suitable for use in a seat such as a driver's cab of a tractor or trailer head that pulls a trailer when a vehicle such as an automobile is running.
一般に自動車等の乗員、例えばドライバ等にと
つて、上下方向の振動よりも前後方向の振動の方
が、より一層不快感を引き起こすものである。特
にトレーラを牽引するトラクタ等においては大き
な前後方向の振動が座席に生ずるので、このよう
な場合には必要に応じて座席に発生する前後方向
の振動を吸引することが好ましい。 In general, vibrations in the longitudinal direction cause more discomfort to occupants of automobiles, such as drivers, etc., than vibrations in the vertical direction. Particularly in the case of a tractor that tows a trailer, large longitudinal vibrations occur in the seat, so in such a case, it is preferable to absorb the longitudinal vibrations generated in the seat as necessary.
そこで従来、上述の如き前後方向の振動を吸収
するための機能を備えた座席支持装置が提案され
ているが、斯る従来の座席支持装置の場合、座席

に、前後の振動を吸収するための前後支持(サス
ペンシヨン)機構のロツクオン、オフの操作レバ
ーがあり、前後支持機構をロツクオフにした状態
のままで座席スライド機構のロツクオフも可能な
ため、両機構のロツクオフ時は座席の位置調整を
行なうとすると前後支持機構も作動してしまい座
席が動いて座席の位置をうまく決めることができ
ず、また座席スライド用の操作レバーと座席支持
用の操作レバーとを夫々別個に設けているので構
造が複雑で高価となる等の欠点があつた。 Therefore, conventional seat support devices have been proposed that have the function of absorbing vibrations in the longitudinal direction as described above, but in the case of such conventional seat support devices, although they are mounted on the seat slide rail, Separately from the lock-on and lock-off control levers of the original seat slide mechanism for sliding the seat forward and backward to position the seat, there are lock-on and lock-off control levers for the front and rear support (suspension) mechanism to absorb back and forth vibrations. It is possible to lock off the seat slide mechanism while the front and rear support mechanisms are locked off, so if you try to adjust the seat position when both mechanisms are locked off, the front and rear support mechanisms will also operate, causing the seat to move and cause the seat to shift. It is difficult to determine the position well, and since the operating lever for sliding the seat and the operating lever for supporting the seat are provided separately, the structure is complicated and expensive.
本考案は斯る点に鑑みてなされたもので、単一
の操作レバーで座席スライド機構と前後支持機構
のロツク状態を互いに一方がロツクオンのとき他
方がロツクオフとなるようにして座席の位置決め
を容易ならしめると共に構造の簡略化をはかり、
しかも前後方向の振動の吸収が却つて不快感を生
ずる時は必要に応じてこれを解除できる座席支持
装置を提供するものである。 The present invention was developed in view of this point, and it is possible to easily position the seat by using a single operating lever to lock the seat slide mechanism and the longitudinal support mechanism so that when one is locked on, the other is locked off. In addition to standardizing the structure, we aim to simplify the structure.
Furthermore, the present invention provides a seat support device that can cancel the absorption of vibrations in the longitudinal direction as necessary when the absorption of vibrations causes discomfort.

よつて前後方向の振動が吸収されることになる。 Further, a plate 9 is fixed to the operating lever 3 inside the second lock plate 7. This plate 9 has protrusions 9a projecting on both sides, and steps 6b and 7b are provided at both ends of the circumference of the lock plates 6 and 7, respectively, around the operating lever 3.
When the operating lever 3 is rotated, the two lock plates 6 and 7 are engaged with each other and act to rotate both the lock plates 6 and 7.
Then, a hook piece 10 is fixed to the first lock plate 6, and this hook piece 10 and the second lock plate 7 are connected to each other.
If a biasing member such as a spring 11 is stretched between the hole 7c provided in the lock portion 7a of the first lock plate 6 and the second lock plate 6, the lock portion 6a of the first lock plate 6 and the second lock plate 6 are pulled together. The lock portions 7a of the lock plate 7 are connected to the notches 5b of the bracket 5, respectively.

い。 To move the seat 1 from this state and fix it in a proper position, the operating lever 3 is rotated in the direction of arrow C. Then, due to the rotation of the operating lever 3, the plate 9 fixed to this lever also rotates in the direction of arrow C, so that the protrusions 9a at both ends engage with the step 7b of the second lock plate 7, and this second lock plate 7 in the direction of arrow C. The protrusion 7a of the lock plate 7 which was engaged with the hole 2b1 of the stationary side rail 2b due to the rotation of the second lock plate 7
As shown in FIG. 3, the movable side rail 2a and the fixed side rail 2b are disengaged from each other through the hole 2b1 . As a result, the seat 1 mounted on the movable rail 2a can move freely. At this time, spring 11
The protrusion 6a of the first lock plate 6 due to the biasing force of
is in a state in which it engages with the notch 5b of the bracket 5, that is, in a locked-on state of the front and rear support mechanism, so that the seat 1 does not move back and forth and it is difficult to set its position because the front and rear support mechanism does not work.

れる。 In such a state, the operating lever 3 is rotated in the direction of arrow D in order to absorb the longitudinal vibration of the seat 1. Then, by rotating the operating lever 3, the plate 9
also rotates in the direction of arrow D, so the protrusions 9 at both ends
a engages with the stepped portion 6b of the first lock plate 6, causing the first lock plate 6 to rotate in the direction of arrow D. As the first lock plate 6 rotates, the protrusion 6a of the first lock plate 6, which was engaged with the notch 5b of the bracket 5 fixed to the movable side rail 2a, comes off the notch 5b and moves to the fixed side as shown in FIG. The second rail is locked on to rail 2b.
The lock plate 7 and the space between the first lock plate 6 and the bracket 5 that circumscribe the lock plate 7 become free, and the vibrations of the seat 1 in the longitudinal direction are absorbed by the spring 8 disposed between the bracket 5 and the first lock plate 6.

ー3の回転方向を変えて行なうようにしたので、
操作が簡単となると共に構造も簡単となる。 As described above, according to this embodiment, the positioning of the seat 1 and the absorption of vibrations in the longitudinal direction of the seat 1 are performed by changing the direction of rotation of the operating lever 3.
It is easy to operate and has a simple structure.
また座席1の位置決めの際には前後支持機構は
ロツクオン状態つまり前後支持機構が働かないよ
うにしたので、座席1を確実にしかも容易に位置
決めできる。 Further, when positioning the seat 1, the front and rear support mechanisms are in a locked-on state, that is, the front and rear support mechanisms are not activated, so that the seat 1 can be positioned reliably and easily.
更に前後支持機構の機能は必要に応じて解除で

を保持することができる。 Therefore, in this embodiment as well, by rotating the operating lever 23 in the direction of arrow C, the protrusion 27a of the second lock plate 27 comes out of the hole 2b1 of the fixed side rail 2b and the seat slides as shown in FIG. The mechanism is locked off, that is, the seat 1 is free to move. On the other hand, by rotating the operating lever 23 in the direction of arrow D, the protrusion 26a of the first lock plate 26 is moved into the notch 2 of the bracket 25, as shown in FIG.
5b, the front-rear support mechanism becomes locked off, and vibrations of the seat 1 in the front-rear direction are absorbed. As can be seen from FIG. 9, this state is maintained because the spring member 11 exceeds the axial center 23c of the operating lever 23, and the lock-off state of the front and rear support mechanism can be maintained.
この前後支持機構のロツクオフ状態は操作レバ
ー23を元に戻すことによりばね部材11が軸中
心23cを越えて解除され、前後支持機構はロツ
クオン状態、つまり前後方向の振動を吸収しない
状態となる。 The lock-off state of the front-rear support mechanism is released by returning the operating lever 23 to its original position so that the spring member 11 crosses the shaft center 23c, and the front-rear support mechanism enters a lock-on state, that is, a state in which vibrations in the front-rear direction are not absorbed.

振動を吸収するための前後支持機構のロツク状態
を夫々単一の操作レバーでその操作方向を変える
ことにより制御するようにしたので操作が簡単と
なると共に構造も簡略化される。 As described above, according to the present invention, the locking state of the seat slide mechanism for adjusting the seat position and the front and rear support mechanism for absorbing vibrations in a predetermined direction of the seat can be changed by using a single operating lever. Since it is controlled by this method, the operation is simple and the structure is also simplified.
また座席スライド機構と前後支持機構のロツク
状態を交互に作動するようにしたので、座席の位
置決めの際には前後支持機構が働かず、もつて座
席を確実にしかも容易に適正位置に設定できる。 In addition, since the locking state of the seat slide mechanism and the front and rear support mechanisms are operated alternately, the front and rear support mechanisms do not work when positioning the seat, so that the seat can be reliably and easily set at the proper position.
更に前後支持機構の機能は必要に応じて解除で
きるようにしたので、前後方向の振動の吸収が逆
に不快感を生ずる時は前後支持機構の機能を停止
できる等任意の使用態様に対応できる。 Furthermore, the function of the front and back support mechanism can be canceled as necessary, so that when absorbing vibrations in the front and back direction causes discomfort, the function of the front and rear support mechanism can be stopped, allowing for any usage mode.
