Description

本発明は、シート本体のシートフレームをシートの前後スライド装置に取付けるためのシート締結構造に関するものである。 The present invention relates to a seat fastening structure for attaching a seat frame of a seat body to a seat front / rear slide device.

自動車のシートは、一般的に、前後の位置を調整するために、シートスライド調整装置を備え、このシートスライド調整装置には、シートスライドレールを車体に精度よく取付けるための技術がある（例えば、特許文献１参照。）。
特開２００２−３３１８６０公報（第４頁、図１） In general, an automobile seat is provided with a seat slide adjusting device for adjusting the front-rear position, and this seat slide adjusting device has a technique for accurately attaching a seat slide rail to a vehicle body (for example, (See Patent Document 1).
JP 2002-331860 (page 4, FIG. 1)

特許文献１を次図に基づいて説明する。
図６は、従来の技術の基本構成を説明する図であり、従来のロングスライドレールのロケート構造２０１は、シートスライドレール２０２の一端にロケートピン２０３を取付け、他端にシートレッグアセンブリ２０４を配置し、それぞれのロケートピン２０３を車体フロア２０５の２個のロケート孔２０６にそれぞれ嵌めて一端の位置決めを行い、シートレッグアセンブリ２０４で予め他端のシートスライドレール２０２間のピッチを定める。従って、２本のシートスライドレール２０２間の平行度とピッチ出し作業は簡単になるというものである。 Patent document 1 is demonstrated based on the following figure.
FIG. 6 is a diagram for explaining a basic configuration of a conventional technique. A conventional long slide rail locating structure 201 has a locating pin 203 attached to one end of a seat slide rail 202 and a seat leg assembly 204 arranged at the other end. Each locating pin 203 is fitted into the two locating holes 206 of the vehicle body floor 205 to position one end, and the seat leg assembly 204 predetermines the pitch between the seat slide rails 202 at the other end. Accordingly, the parallelism between the two seat slide rails 202 and the pitching operation are simplified.

しかし、特許文献１のロングスライドレールのロケート構造２０１では、車体フロア２０５に開けたロケート孔２０６を基準に位置決めを行うため、既に別の場所で組立てたロケートピン２０３間のピッチを無理やり、ロケート孔２０６間のピッチに一致させる場合も考えられる。別の場所で設定した２本のシートスライドレール２０２とシートレッグアセンブリ２０４との間に弾性変形による拘束力が発生して、シート本体（シートレッグアセンブリ２０４）をスライドさせる操作力が大きくなるおそれがある。結果的に、微調整作業が必要となることもある。 However, in the long slide rail locating structure 201 of Patent Document 1, since positioning is performed based on the locating hole 206 opened in the vehicle body floor 205, the pitch between the locating pins 203 already assembled in another place is forcibly set. It is also conceivable to match the pitch between. There is a possibility that a restraining force due to elastic deformation is generated between the two seat slide rails 202 and the seat leg assembly 204 set at different places, and an operating force for sliding the seat body (the seat leg assembly 204) is increased. is there. As a result, fine adjustment work may be required.

また、特許文献１では、車体フロア側にシートレッグアセンブリ２０４を取付けた後に、シートレッグアセンブリ２０４にシート本体（シートフレームを含む）を取付けるが、別な構造として、シートレッグアセンブリ２０４にシート本体のシートフレームを一体的に取付けて、シート本体を載せたシートレッグアセンブリ２０４をランナアセンブリ２０７に取付けるものもあり、このような場合、ランナアセンブリ２０７に締結する際に用いる締め付け装置がシート本体に干渉し、作業性は悪くなる。 In Patent Document 1, a seat body (including a seat frame) is attached to the seat leg assembly 204 after the seat leg assembly 204 is attached to the vehicle body floor side. In some cases, the seat frame is integrally attached and the seat leg assembly 204 on which the seat body is mounted is attached to the runner assembly 207. In such a case, a fastening device used when fastening the runner assembly 207 interferes with the seat body. The workability will be worse.

本発明は、前後に移動するスライド手段側とシートフレーム間の寸法のばらつきを吸収して、シートフレームとスライド手段との間に生じる拘束力を極めて小さくすることができ、シート本体を最後に取付けてもシート本体取付け作業は容易なシート締結構造を提供することを課題とする。 The present invention absorbs the dimensional variation between the slide means side that moves back and forth and the seat frame, and the restraining force generated between the seat frame and the slide means can be extremely reduced, and the seat body is attached last. However, an object of the present invention is to provide a seat fastening structure in which the seat body mounting operation is easy.

つまり、めねじ孔８５，８５の前後位置のばらつき、を孔（長孔）１２３，１２６で吸収することができる。 That is, variations in the front and rear positions of the female screw holes 85 and 85 can be absorbed by the holes (long holes) 123 and 126.

その結果、スライド手段３６，３５側とシートフレーム２１間に寸法のばらつきによって生じることのあるピッチや平行度を変えるように加わる拘束力を開放（吸収）して、シートフレーム２１と左・右スライド手段３６，３５と左・右レール３２，３３間に残留するストレス（スライドに対する抵抗となる拘束力）を最小限に抑えることができる。 As a result, the restraining force applied so as to change the pitch and parallelism that may be caused by dimensional variations between the slide means 36, 35 side and the seat frame 21 is released (absorbed), and the seat frame 21 and the left / right slide The stress remaining between the means 36, 35 and the left and right rails 32, 33 (restraint force acting as a resistance against sliding) can be minimized.

より詳しくは、位置決め孔（長孔）６２，６３でも吸収することで、ピッチや平行度を変えるように加わる拘束力を開放（吸収）し、シートフレーム２１と左・右スライド手段３６，３５と左・右レール３２，３３間に残留するストレス（スライドに対する抵抗となる拘束力）を最小限に抑えることができる。 More specifically, by absorbing the positioning holes (long holes) 62 and 63 to release (absorb) the binding force applied to change the pitch and parallelism, the seat frame 21 and the left and right slide means 36 and 35 The stress remaining between the left and right rails 32 and 33 (restraint force acting as resistance against sliding) can be minimized.

このように、シート締結構造１１では、シート（左シート）１３のシートフレーム２１の一方の脚部（右脚部）１０１を前後スライド装置（シートスライド装置）１７の一方のスライド手段（右スライド手段）３５に載せ、他方のスライド手段（左スライド手段）３６に他方の脚部（左脚部）１０２を載せる場合に、一方の脚部（右脚部）１０１に形成した下面１１１の前部１１２及び後部１１３にそれぞれ位置決めピン１１４，１１５を取付け、これらの位置決めピン１１４，１１５が各嵌る位置決め孔６２，６３を左右方向（図２の矢印ａ２の方向）に長い長孔で一方のスライド手段（右スライド手段）３５に開け、他方の脚部（左脚部）１０２の横面１２２，１２５に前後方向（図３の矢印ａ３の方向）に長い長孔１２３，１２６を開け、この長孔１２３，１２６に対応する孔（めねじ孔）８５，８５を他方のスライド手段（左スライド手段）３６の横面８４に開け、位置決めピン１１４，１１５を嵌めた後に、横面１２２，１２５を締結するので、一方のスライド手段（右スライド手段）３５と一方の脚部（右脚部）１０１とを基準に締結する過程で、スライド手段（左・右スライド手段）３６，３５側とシートフレーム２１との間の寸法のばらつきを吸収して、シートフレーム２１とスライド手段（左・右スライド手段）３６，３５との間に生じるスライドの際の抵抗となる拘束力を極めて小さくすることができる。 As described above, in the seat fastening structure 11, one leg portion (right leg portion) 101 of the seat frame 21 of the seat (left seat) 13 is moved to one slide means (right slide means) of the front / rear slide device (seat slide device) 17. ) 35 and when the other leg (left leg) 102 is placed on the other slide means (left slide means) 36, the front portion 112 of the lower surface 111 formed on one leg (right leg) 101. And positioning pins 114 and 115 are attached to the rear portion 113, respectively, and the positioning holes 62 and 63 into which the positioning pins 114 and 115 are fitted respectively are formed as one slide means (in the direction of the arrow a2 in FIG. 2) with a long hole. (Right slide means) 35, and long holes 123, 126 that are long in the front-rear direction (in the direction of arrow a3 in FIG. 3) are opened on the lateral surfaces 122, 125 of the other leg (left leg) 102. Then, holes (female screw holes) 85 and 85 corresponding to the long holes 123 and 126 are formed in the lateral surface 84 of the other slide means (left slide means) 36, and after positioning pins 114 and 115 are fitted, the lateral surface 122 , 125 are fastened, and in the process of fastening on the basis of one slide means (right slide means) 35 and one leg (right leg) 101, the slide means (left / right slide means) 36, 35 side By absorbing the dimensional variation between the seat frame 21 and the seat frame 21, the restraining force, which is a resistance when sliding between the seat frame 21 and the slide means (left / right slide means) 36, 35, is extremely small. be able to.

図５は、本発明のシート締結構造の第２作用図である。図３、図４を併用して説明する。
左・右スライド手段３６，３５にそれぞれ左脚部（他方の脚部）１０２、右脚部（一方の脚部）１０１を載せた後、まず、左脚部（他方の脚部）１０２にボルト１２９（図３参照），１２９（図３参照）をねじ込む。
ボルト１２９（図３参照），１２９（図３参照）は、軸線を車両１５の左右方向に向けた横向き（矢印ａ４の方向）としたので、ボルト１２９，１２９を締め付けるレンチ１３１は後ドア２６の位置で横向き（矢印ａ４の方向）となり、左スライド手段３６及び左脚部（他方の脚部）１０２は、無理のない作業姿勢を確保しつつ、周囲のものとの干渉を防止することができる。 FIG. 5 is a second operation view of the seat fastening structure of the present invention. This will be described with reference to FIGS.
After the left leg portion (the other leg portion) 102 and the right leg portion (the one leg portion) 101 are placed on the left and right slide means 36 and 35, respectively, first, a bolt is attached to the left leg portion (the other leg portion) 102. Screw 129 (see FIG. 3) and 129 (see FIG. 3).
Since the bolts 129 (see FIG. 3) and 129 (see FIG. 3) are oriented sideways (in the direction of the arrow a4) with the axis line in the left-right direction of the vehicle 15, the wrench 131 for tightening the bolts 129 and 129 is provided on the rear door 26. The left slide means 36 and the left leg portion (the other leg portion) 102 can prevent interference with surroundings while ensuring a comfortable working posture. .

ボルト１２９，１２９を、約９５％程度までねじ込むと、シートフレーム２１は右（矢印ａ５の方向）にわずかに動く。このとき、予め右スライド手段３５の位置決め孔６２，６３は共に、左右方向（矢印ａ２）に長い長孔としたので、シートフレーム２１が右（矢印ａ５の方向）へ移動する際に、干渉せず、シートフレーム２１を右（矢印ａ５の方向）へ微動させて、左右方向の位置決めを行うことができるとともに、右スライド手段３５に加わる曲げ力（矢印ａ５の方向）を除去することができる。 When the bolts 129 and 129 are screwed to about 95%, the seat frame 21 slightly moves to the right (in the direction of the arrow a5). At this time, since the positioning holes 62 and 63 of the right slide means 35 are both elongated holes in the left-right direction (arrow a2) in advance, interference occurs when the seat frame 21 moves to the right (direction of arrow a5). First, the seat frame 21 can be finely moved to the right (in the direction of the arrow a5) to perform positioning in the left-right direction, and the bending force (in the direction of the arrow a5) applied to the right slide means 35 can be removed.

引き続き、右脚部（一方の脚部）１０１にボルト１２８（図３参照），１２８（図３参照）をねじ込む。ボルト１２８（図４参照），１２８（図４参照）は、軸線をそれぞれ前後に角度θ，θだけ傾けたので、ボルト１２８，１２８を締め付けるレンチ１３１は角度θだけ寝かせた状態となり、右スライド手段３５及び右脚部（一方の脚部）１０１は、無理のない作業姿勢を確保しつつ、周囲のものとの干渉を防止することができる。 Subsequently, bolts 128 (see FIG. 3) and 128 (see FIG. 3) are screwed into the right leg (one leg) 101. Since the bolts 128 (see FIG. 4) and 128 (see FIG. 4) have their axes tilted forward and backward by angles [theta] and [theta], the wrench 131 for tightening the bolts 128 and 128 is laid down by the angle [theta], so 35 and the right leg part (one leg part) 101 can prevent interference with the surrounding thing, ensuring a comfortable working posture.

ボルト１２８，１２８を締め付け、右スライド手段３５の前・後斜め部５６，５７に右脚部（一方の脚部）１０１の接続前斜め部１０５及び接続後斜め部１０６をそれぞれ密着させてボルト１２８，１２８に所定の軸力（例えば、トルク管理）を付与する。
最後に、ボルト１２９，１２９を残り５％ねじ込み、ボルト１２９，１２９に所定の軸力（例えば、トルク管理）を付与する。
従って、シート（左シート）１３のシート本体１８を最後に取付けてもシート本体取付け作業は容易である。 The bolts 128 are tightened, and the front and rear oblique portions 56 and 57 of the right slide means 35 are brought into close contact with the oblique portion 105 before connection and the oblique portion 106 after connection of the right leg portion (one leg portion) 101, respectively. , 128 is given a predetermined axial force (for example, torque management).
Finally, the remaining 5% of the bolts 129 and 129 are screwed and a predetermined axial force (for example, torque management) is applied to the bolts 129 and 129.
Therefore, even if the seat body 18 of the seat (left seat) 13 is attached last, the seat body attaching operation is easy.
