【発明の属する技術分野】
本発明は自動車用シートのリクライニング装置、詳しくは、リャシートにおいてそのシートバックの上部にロック解除用操作レバーを有し、この操作レバーの引き上げ操作によりシートバックのロック解除を行うリクライニング装置に関する。
【0002】
【従来の技術】
自動車用シートのリクライニング装置には、シートバックの下部とシートクッション側の間に、シートバックを所望の傾動角度で保持する係止手段を設け、この係止手段にプルワイヤを介して連結する操作レバーをシートバックの上部に配設して、操作レバーの引き上げ操作力によって前記係止手段によるロック解除を行うものがある(例えば、実開平3ー27743号公報)。
【0003】
この従来品を図3、図4に基づいて説明すると、シートバックを構成するパネル(7)に一体に溶接されているパイプ製のバックフレーム(70)のサイド側部には取付ブラケット(5)が固着され、この取付ブラケット(5)にリクライニング装置を構成するアッパーアーム(4)が締結されている。
図中(71)は、コ字状に折曲するバックフレーム(70)の両端を連結する連結フレームを示す。
【0004】
また、シートクッションのシートフレーム(6)には、ベースプレート(3)が固定され、このベースプレート(3)に前記アッパーアーム(4)を前後方向に回動自在に軸支されるロアアーム(30)が設けてあり、このロアアーム(30)とアッパーアーム(4)とにシートバックを所望の傾斜角度に保持する係止手段が設けてある。
【0005】
そして、この係止手段にプルワイヤ(100)を介してシートバックの上部に配設したロック解除用の操作レバー(200)が連結されており、操作レバー(200)は一端側を軸支ピン(210A)によってブラケット(210)に回動自在に軸着され、操作レバー(200)を引き上げ方向に回動させると、プルワイヤ(100)が引き上げられて前記係止手段によるロック状態が解除されるようになっている。
【0006】
以上の操作レバー(200)、プルワイヤ(100)は図4に示すように構成されている。
操作レバー(200)は、一端側に前記軸支ピン(210A)を挿通する通孔(200A)、他端側に操作部(200B)をそれぞれ有し、略中央にプルワイヤ(100)を連結するための連結孔(201)が開孔されている。
【0007】
プルワイヤ(100)は、線径が4mm程度の軟鋼線(SWMーB)で直線状に折曲した上、下端部(101)(102)を、合成樹脂製プッシュ(300)を介して前記金属製の操作レバー(200)、ロック解除用可動カム(40)に連結して異音の発生を防止している。
【0008】
ブッシュ(300)には、プルワイヤ(100)を上下方向に挿通する筒部(302)と、ワイヤ(100)の上、下端部(101)(102)を挿通して前記連結孔(201)、可動カム(40)の連結孔(40A)に巻込む突起(301)とが設けてある。図中(301A)はプルワイヤ(100)の上、下端部(101)(102)が挿込まれる通孔を示し、可動カム(40)をプルワイヤ(100)で回動させると、係止手段によるロック状態が解除されるようになっている。
【0009】
そして、前記プルワイヤ(100)は、連結フレーム(71)に接触しないように折曲部(100A)が形成されている。
【0010】
【発明が解決しようとする課題】
以上の従来品はプルワイヤ(100)の上、下端部(101)(102)をブッシュ(300)に取付後、操作レバー(200)にブッシュ(300)を介して連結している。
また、連結フレーム(71)などの障害物に対する接触を防止するために、曲げ加工が必要であった。
従って、プルワイヤ(100)の操作レバー(200)に対する取付作業が面倒で、その作業性が悪いし、また、プルワイヤ(100)自体の加工性も悪い不具合があった。
【0011】
そこで、本発明は斯様な従来品による不具合を除去することを目的とする。
【0012】
【課題を解決するための手段】
以上の目的を達成するための本発明に係るリクライニング装置は、前記操作レ バーには前記プルワイヤ連結用の突起と、プルワイヤの先端を掛止する掛止部とを 設け、前記プルワイヤには前記操作レバーの突起の外径に対して内径が小径で突起 を弾性によって弾接状に緊締する環状の巻回部と、前記掛止部に先端が掛止される 直線状の係止部とを設けてなることを特徴とするものである。
【0013】
プルワイヤを硬鋼線で形成するため、全体を直線状に形成できると共に軽量化が図れる。
【0014】
【発明の実施の形態】
以下、本発明の実施の一形態を図1、図2に基づいて説明する。
プルワイヤ(1)は、線径が1、4mm程度の硬鋼線(SBW)で、その上端部側に環状(ループ状)に折曲した巻回部(11)を有し、直線状の上端部を係止部(10)とする。
【0015】
プルワイヤ(1)の下端部側は、従来の係止手段によるロック状態を解除する解除部材(不図示)に設けた連結突部に挿し込み連結されるように折り返されており、この折り返し部分を折返部(12)とし、この折返部(12)は柔軟弾性を有する筒状の消音材(13)に被着されている。
【0016】
操作レバー(2)は、従来と同様に一端部がシートバックの上部に枢支ピンによって上下方向に回動自在に枢支され、他端側の操作部(2B)を上方に回動操作することにより、プルワイヤ(1)が引かれて係止手段によるロック状態が解除されるようになっている。
図中(2A)は、操作レバー(2)を回動自在に枢支する枢支ピンの通孔を示す。
【0017】
この操作レバー(2)には、前記プルワイヤ(1)の巻回部(11)が巻回されるプルワイヤ連結用の突起(21)と、プルワイヤ(1)の係止部(10)が掛止される掛止部(20)が設けてある。
【0018】
突起(21)は、操作レバー(2)の回動方向に対して直交状に操作レバー(2)の段部(2C)に突出成形されている全体が矢印状体、即ち、先鋭状の拡大頭部を有し、下部の外径(L1)がプルワイヤ(1)の巻回部(11)の内径(L2)に対して大に成形されている。
【0019】
掛止部(20)は、プルワイヤ(1)の巻回部(11)を突起(21)に装着後、その内径(L2)が拡大しないように係止部(10)を掛止するもので、図示するものは操作レバー(2)に設けた通孔であるが、この通孔の代わりに操作レバー(2)の一端縁側を突起(21)方向に折曲したものでも良い。
【0020】
以上のプルワイヤ(1)の巻回部(11)内に、巻回部(11)の弾性に抗して操作レバー(2)の突起(21)を挿し込むと、巻回部(11)の内径は拡大し内部に突起(21)が挿し込まれ、また、係止部(10)を通孔からなる掛止部(20)に差し込むと、図2に示すように、プルワイヤ(2)が操作レバー(2)に取付けられる。
【0021】
操作レバー(2)に取付けられたプルワイヤ(1)の巻回部(11)は、その弾性により突起(21)に弾接状に緊締するため、自動車の振動により異音が発生しない。そして、プルワイヤ(1)の係止部(10)が操作レバー(2)の掛止部(20)に掛止されているため、巻回部(11)の突起(21)に対する緊締状態が良好で緩むことがない。
【0022】
従って、従来と同様に操作レバー(2)を矢印方向(図2)に回動操作すると、プルワイヤ(1)が引かれて係止手段によるシートバックのシートクッションに対するロック状態が解除になり、シートバックの傾動角度を所望の角度に調節し得る状態となる。
【0023】
また、前記プルワイヤ(1)は、以上の如く線径が細い硬鋼線を使用することにより、柔軟弾性を有し前記連結フレーム(70)などの障害物が存在しても、前記従来品の如く曲げ加工することがない。
【0024】
【発明の効果】
本発明によれば、プルワイヤの巻回部を操作レバーの突起に押し込むことにより巻回部が拡大して突起に装着でき、装着後は巻回部の弾性により突起を緊締して連結され、プルワイヤの係止部を操作レバーの掛止部に掛止することにより、前記連結状態が保持される。
【0025】
従って、プルワイヤの巻回部の弾性によりプルワイヤを操作レバーに連結するため、前記従来品の如くブッシュなどの異音発生防止部材が不要になるし、直接プルワイヤを操作レバーに取付けることができるため、プルワイヤの操作レバーに対する取付性を向上させることができる。
【0026】
加えて、巻回部が弾性を有するように、硬鋼線でプルワイヤを形成しているため、プルワイヤの配設個所に突起物などが存在する場合においても、前記従来品の如く突起物をさけるための曲げ加工が不要となる。

[0013]
Since the pull wire is formed of a hard steel wire, the whole can be formed in a straight line, and the weight can be reduced.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
The pull wire (1) is a hard steel wire (SBW) having a wire diameter of about 1 to 4 mm, and has a winding portion (11) bent in an annular shape (loop shape) on the upper end side, and has a linear upper end. Let the part be a locking part (10).
[0015]
The lower end portion side of the pull wire (1) is folded back so as to be inserted and connected to a connecting projection provided on a release member (not shown) that releases the locked state by the conventional locking means. The folded portion (12) is attached to a cylindrical sound deadening material (13) having flexible elasticity.
[0016]
The operation lever (2) has one end pivotally supported by a pivot pin on the upper portion of the seat back so that the operation lever (2) is pivotable in the vertical direction, and the other end side operation portion (2B) is pivoted upward. Thus, the pull wire (1) is pulled and the locked state by the locking means is released.
In the figure, (2A) shows a through hole of a pivot pin that pivotally supports the operation lever (2).
[0017]
The operation lever (2) has a pull wire connecting projection (21) around which the winding portion (11) of the pull wire (1) is wound, and an engaging portion (10) of the pull wire (1). A latching portion (20) is provided.
[0018]
The protrusion (21) is projected and formed on the step portion (2C) of the operation lever (2) perpendicular to the rotation direction of the operation lever (2). It has a head and the outer diameter (L 1 ) of the lower part is formed larger than the inner diameter (L 2 ) of the winding part (11) of the pull wire (1).
[0019]
Latching portion (20) after mounting the winding portion of the pull wire (1) to (11) the projection (21), its inner diameter (L 2) which is hooked engaging portion (10) so as not to enlarge Thus, what is shown is a through hole provided in the operating lever (2), but instead of this through hole, one end edge side of the operating lever (2) may be bent in the direction of the protrusion (21).
[0020]
When the protrusion (21) of the operating lever (2) is inserted into the winding part (11) of the pull wire (1) against the elasticity of the winding part (11), the winding part (11) When the inner diameter is enlarged and the protrusion (21) is inserted therein, and when the engaging portion (10) is inserted into the latching portion (20) formed of a through hole, the pull wire (2) is formed as shown in FIG. It is attached to the operating lever (2).
[0021]
Since the winding part (11) of the pull wire (1) attached to the operation lever (2) is elastically tightened to the protrusion (21) by its elasticity, no abnormal noise is generated by vibration of the automobile. And since the latching | locking part (10) of a pull wire (1) is latched by the latching | locking part (20) of an operation lever (2), the tightening state with respect to the processus | protrusion (21) of a winding part (11) is favorable. Will not loosen.
[0022]
Accordingly, when the operation lever (2) is rotated in the direction of the arrow (FIG. 2) as in the prior art, the pull wire (1) is pulled, and the locking state of the seat back on the seat back by the locking means is released, and the seat The back tilt angle can be adjusted to a desired angle.
[0023]
Further, the pull wire (1) is made of a hard steel wire having a thin wire diameter as described above, so that even if there is an obstacle such as the connecting frame (70), the pull wire (1) has the flexible elasticity. It is not bent like.
[0024]
【The invention's effect】
According to the present invention, when the winding portion of the pull wire is pushed into the protrusion of the operation lever, the winding portion can be enlarged and attached to the protrusion, and after the attachment, the protrusion is tightened and connected by the elasticity of the winding portion. The above-mentioned connected state is maintained by hooking the latching portion on the latching portion of the operation lever.
[0025]
Therefore, since the pull wire is connected to the operation lever by the elasticity of the winding portion of the pull wire, an abnormal sound generation preventing member such as a bush is not required as in the conventional product, and the pull wire can be directly attached to the operation lever. The attachment property of the pull wire to the operation lever can be improved.
[0026]
In addition, since the pull wire is formed of a hard steel wire so that the winding portion has elasticity, even when there is a projection or the like at the place where the pull wire is disposed, the projection is avoided like the conventional product. Bending is not necessary.
