次に、この発明の実施形態を図面に基づいて説明する。
図1に示すように、車両用のシート装置1はアーチ状のシートバックフレーム2とシートクッションフレーム3を備えている。シートバックフレーム2の左右の下端部にシャフト4が取り付けられ、このシャフト4を中心にしてシートクッションフレーム3の後端部が回動可能に支持されている。ここで、シートバックフレーム2にはシートバックパッド8が取り付けられ、シートクッションフレーム3にはシートクッションパッド15が取り付けられている。
Next, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a vehicle seat device 1 includes an arch-shaped seat back frame 2 and a seat cushion frame 3. A shaft 4 is attached to the left and right lower end portions of the seat back frame 2, and the rear end portion of the seat cushion frame 3 is rotatably supported around the shaft 4. Here, a seat back pad 8 is attached to the seat back frame 2, and a seat cushion pad 15 is attached to the seat cushion frame 3.

シートバックフレーム2は下部に断面コの字状に形成され互いに開口部を対向させた左右一対のロアフレーム5を備えている。ロアフレーム5は上側ほど前後方向の幅寸法が小さくなるように形成され、左右のロアフレーム5,5の上端部にはパイプ材からなる門型のアッパフレーム6が接合されている。
シートクッションフレーム3は前端部が連結ロッド7で連結され後端部が立ち上がるように形成された部材であって、後端部にシャフト4を介してシートバックフレーム2が前後方向に回動可能に支持されている。
The seat back frame 2 includes a pair of left and right lower frames 5 formed in a U-shaped cross section at the lower portion and having openings facing each other. The lower frame 5 is formed so that the width dimension in the front-rear direction becomes smaller toward the upper side, and a gate-shaped upper frame 6 made of a pipe material is joined to upper ends of the left and right lower frames 5 and 5.
The seat cushion frame 3 is a member formed such that the front end portion is connected by a connecting rod 7 and the rear end portion rises, and the seat back frame 2 can be rotated in the front-rear direction via the shaft 4 at the rear end portion. It is supported.

図2は図1のA−A線に沿う断面図である。シートバックフレーム2の前面にはシートバックフレーム2を覆うようにしてシートバックパッド8が設けられている。このシートバックパッド8は、背もたれ部9と、この背もたれ部9の両側部に、前側に向かって断面U字状に張り出すサイドサポート部10,10とで形成されている。
サイドサポート部10の後部には凹部11が形成され、この凹部11にシートバックフレーム2のロアフレーム5が収容されている。ここで、シートバックパッド8は、後述する帯状部材20を含めて後面を図示しない表皮材より覆われている。
FIG. 2 is a cross-sectional view taken along line AA in FIG. A seat back pad 8 is provided on the front surface of the seat back frame 2 so as to cover the seat back frame 2. The seat back pad 8 is formed of a backrest portion 9 and side support portions 10 and 10 that protrude in a U-shaped cross section toward the front side on both sides of the backrest portion 9.
A concave portion 11 is formed in the rear portion of the side support portion 10, and the lower frame 5 of the seat back frame 2 is accommodated in the concave portion 11. Here, the seat back pad 8 is covered with a skin material (not shown) including the belt-like member 20 described later.

図3にも示すように、一方のロアフレーム5には前壁12にコの字形のブラケット13が取り付けられ、このブラケット13に帯状部材20の端末21が折り返して縫合などにより接合されている。
図4に示すように、帯状部材20はシートバックパッド8の背面に沿って幅方向に延出され、他方のロアフレーム5の前壁12に設けたブラケット19の滑車22に掛け渡されて、帯状部材20の他の端末23が巻き取り機構24によって巻き取られている。
巻き取り機構24は、滑車22に支持された他の端末23をモータ25によって巻き取り部26に巻き取る構造となっている。
As shown in FIG. 3, one lower frame 5 has a U-shaped bracket 13 attached to a front wall 12, and a terminal 21 of a belt-like member 20 is folded back and joined to the bracket 13 by sewing or the like.
As shown in FIG. 4, the belt-like member 20 extends in the width direction along the back surface of the seat back pad 8, and is stretched over the pulley 22 of the bracket 19 provided on the front wall 12 of the other lower frame 5. The other end 23 of the belt-like member 20 is taken up by the take-up mechanism 24.
The winding mechanism 24 has a structure in which another terminal 23 supported by the pulley 22 is wound around the winding portion 26 by a motor 25.

この巻き取り機構24による帯状部材20の巻き取り量が多ければ帯状部材20の張力は大きく、巻き取り機構24による帯状部材20の巻き取り量が少なければ、帯状部材20の張力は小さくなるため、この巻き取り機構24の帯状部材20の巻き取り量を変化させることで帯状部材20の張力を調整している。
ここで、ブラケット13及び滑車22の位置はシートバックパッド8の背面8Aよりも前側に設定されている。
If the winding amount of the strip member 20 by the winding mechanism 24 is large, the tension of the strip member 20 is large. If the winding amount of the strip member 20 by the winding mechanism 24 is small, the tension of the strip member 20 is small. The tension of the belt-shaped member 20 is adjusted by changing the winding amount of the belt-shaped member 20 of the winding mechanism 24.
Here, the positions of the bracket 13 and the pulley 22 are set in front of the back surface 8 </ b> A of the seat back pad 8.

そして、図2に示すように帯状部材20とシートバックパッド8との間には、着座した乗員の骨盤の側面付近に対応して左右一対の押圧部材30が挟持して設けられている。シートバックパッド8には押圧部材30の装着部位に、各押圧部材30をはめ込むための嵌合凹部14が形成されている。   As shown in FIG. 2, a pair of left and right pressing members 30 are sandwiched between the belt-like member 20 and the seat back pad 8 so as to correspond to the vicinity of the side surface of the seated occupant's pelvis. The seat back pad 8 is formed with a fitting recess 14 for fitting each pressing member 30 in the mounting portion of the pressing member 30.

図5〜図7は押圧部材30を示している。押圧部材30は樹脂により形成され背面に向かって膨出する形状の部材であって、上下に一対の凸部31を備えている。凸部31は各々上下に向かって傾斜する平坦面37を備え、両方の凸部31の間にシート幅方向に延びる凹形状の摺動面32が形成されている。この摺動面32にはシート幅方向中央を背面に向かって凸となる凸形状部33が形成されている。   5 to 7 show the pressing member 30. The pressing member 30 is a member that is made of resin and has a shape that bulges toward the back surface, and includes a pair of convex portions 31 in the vertical direction. Each of the convex portions 31 includes a flat surface 37 inclined upward and downward, and a concave sliding surface 32 extending in the sheet width direction is formed between both the convex portions 31. The sliding surface 32 is formed with a convex portion 33 that is convex in the center in the sheet width direction toward the back surface.

押圧部材30の前面は凸部31を膨出形成させた部分の裏側にリブ34が十字形状に設けられて補強され、周囲にはフランジ部35が設けられている。フランジ部35によって形成される外縁は方形状でコーナー部分が弧状に形成され上下方向がシート幅方向に比較して長い形状になっている。このフランジ部35の前面がリブ34の上縁と共に平面上に位置している。主としてこのフランジ部35がシートバックパッド8を前側に押圧する平面状の押圧面36を構成している。   The front surface of the pressing member 30 is reinforced by a rib 34 provided in a cross shape on the back side of the portion where the convex portion 31 is bulged, and a flange portion 35 is provided around the periphery. The outer edge formed by the flange portion 35 has a square shape, the corner portion is formed in an arc shape, and the vertical direction is longer than the sheet width direction. The front surface of the flange portion 35 is located on a plane together with the upper edge of the rib 34. The flange portion 35 mainly constitutes a flat pressing surface 36 that presses the seat back pad 8 forward.

上記実施形態によれば、巻き取り機構24により帯状部材20を巻き取ることで、帯状部材20に張力を付与すると、ブラケット13及びブラケット19の滑車22の間に係止された帯状部材20は、ブラケット13及び滑車22がシートバックパッド8の背面8Aよりも前側に位置しているため、帯状部材20のブラケット13と滑車22との間に位置する部位が張力により前側に変位しようとする。   According to the embodiment, when the belt-like member 20 is wound by the winding mechanism 24 to apply tension to the belt-like member 20, the belt-like member 20 locked between the bracket 13 and the pulley 22 of the bracket 19 is Since the bracket 13 and the pulley 22 are located in front of the back surface 8A of the seat back pad 8, the portion of the belt-like member 20 located between the bracket 13 and the pulley 22 tends to be displaced to the front side by tension.

その結果、各押圧部材30は帯状部材20により摺動面32を介して前側に押圧される。前側に押圧された各押圧部材30はシートバックパッド8に形成された嵌合凹部14の位置で、ずれ動くことなくシートバックパッド8を押圧するため、シートバックパッド8は前側に押し出され、着座する乗員の腰部、具体的には骨盤の側面付近を後から前側に向かって押圧し確実に支持して快適な着座状態を維持することができる。つまり、押圧部材30がシートバック(シートバックパッド8)と乗員の腰部との間を埋めることにより、乗員の姿勢を正した状態で支持することができる。   As a result, each pressing member 30 is pressed forward by the strip-shaped member 20 via the sliding surface 32. Each pressing member 30 pressed to the front side presses the seat back pad 8 at the position of the fitting recess 14 formed in the seat back pad 8 without being displaced, so that the seat back pad 8 is pushed forward and seated. A comfortable seating state can be maintained by pressing the lumbar part of the occupant, specifically, the vicinity of the side surface of the pelvis from the rear toward the front side and supporting it reliably. That is, the pressing member 30 can support the occupant in a correct posture by filling the space between the seat back (seat back pad 8) and the occupant's waist.

このとき、押圧部材30は摺動面32を帯状部材20により押圧されるが、押圧部材30の摺動面32をシート幅方向に延びる凹形状としたことで、帯状部材20が上下にずれることがなくなるため、押圧部材30を確実に押圧することができる。
更に、上下方向を規制された状態で帯状部材20は摺動面32を長手方向に滑ることができため、動きがスムーズに行われる。とりわけ、摺動面32にはシート幅方向中央を背面に向かって凸となる凸形状部33が設けられているため、帯状部材20が摺動面32において滑り易くでき、帯状部材20のシート幅方向の移動をスムーズに行うことができる。
At this time, the pressing member 30 presses the sliding surface 32 by the belt-like member 20, but the belt-like member 20 is displaced up and down by making the sliding surface 32 of the pressing member 30 into a concave shape extending in the sheet width direction. Therefore, the pressing member 30 can be reliably pressed.
Further, since the belt-like member 20 can slide on the sliding surface 32 in the longitudinal direction while the vertical direction is restricted, the movement is performed smoothly. In particular, since the sliding surface 32 is provided with a convex portion 33 that is convex in the center in the sheet width direction toward the back surface, the belt-shaped member 20 can be easily slipped on the sliding surface 32, and the sheet width of the belt-shaped member 20 can be reduced. The direction can be moved smoothly.

また、押圧部材30はシートバックパッド8に当接する前面の押圧面36を構成する主として平面状のフランジ部35によって押圧するため、シートバックパッド8を押圧部材30の前面全体で押圧することができ、一箇所に力が集中するのを防止して、シートバックパッド8の部分的変形を防止できる。また、平面状のフランジ部35によって押圧するため乗員の体格差を吸収できる。   Further, since the pressing member 30 is pressed by the mainly flat flange portion 35 that constitutes the pressing surface 36 on the front surface that contacts the seat back pad 8, the seat back pad 8 can be pressed by the entire front surface of the pressing member 30. It is possible to prevent the force from concentrating on one place and to prevent partial deformation of the seat back pad 8. Moreover, since it presses by the planar flange part 35, a passenger | crew's physique difference can be absorbed.

図8〜図10はこの発明の他の実施形態に係る押圧部材40を示している。押圧部材40も樹脂により形成され、背面、前面から見て上下に長い略だ円形状の部材であって前後方向に向かって形成された同心円状の複数の同心リブ41と放射方向に形成された放射リブ42と、略だ円形状の外周リブ43とで形成されている。押圧部材40の背面にシート幅方向に沿って延び各リブ41,42,43を跨る摺動面44が凹形状に形成されている。ここで、摺動面44の両端部は押圧部材40の周縁で切欠部46,46となって形成され、帯状部材20の前側への回り込みを容易にしている。   8 to 10 show a pressing member 40 according to another embodiment of the present invention. The pressing member 40 is also formed of resin, and is formed in a radial direction with a plurality of concentric concentric ribs 41 formed in the front-rear direction, which are substantially elliptical members that are long in the vertical direction when viewed from the back and front. The radiating rib 42 and the substantially elliptical outer peripheral rib 43 are formed. A sliding surface 44 extending in the sheet width direction and straddling the ribs 41, 42, 43 is formed in a concave shape on the back surface of the pressing member 40. Here, both end portions of the sliding surface 44 are formed as notches 46, 46 at the periphery of the pressing member 40, thereby facilitating the wraparound of the belt-shaped member 20 to the front side.

押圧部材40の前面は前述した押圧部材30とは異なり、略中央部を前面に向かって凸形状の押圧面45となっている。つまり各リブ41,42,43の上縁が押圧面45を構成している。
そして、帯状部材20とシートバックパッド8との間に、着座した乗員の骨盤の側面付近に対応して左右一対の押圧部材40が挟持して設けられている。尚、シートバックパッド8には押圧部材40の装着部位に、各押圧部材40をはめ込むための嵌合凹部が形成されているのは前述した実施形態と同様である。
この実施形態によれば、前述した実施形態の基本的効果に加え、押圧部材40の前面が、略中央部を前方に向かって凸形状の押圧面45としたため、シートバックパッド8を介してピンポイントで押圧することができる。よって、乗員の特定の部位を集中的に押圧できる。
Unlike the above-described pressing member 30, the front surface of the pressing member 40 is a pressing surface 45 having a convex shape with a substantially central portion facing the front surface. That is, the upper edge of each rib 41, 42, 43 constitutes the pressing surface 45.
