図1には車両用シートを車両内方側から見た斜視図を示し、図2には車両用シートを車両外方側から見た斜視図を示す。各図において、車両用シートのシート本体SのシートバックS1は、公知のリクライニング構造となっており、シート本体Sの外側面に設けたリクライニングレバー1を後方へ回動操作することによってリクライニングロックが解除されてバネ付勢されたシートバックS1がシートクッションS2上に傾倒されるようになっている。   FIG. 1 is a perspective view of a vehicle seat as viewed from the vehicle inner side, and FIG. 2 is a perspective view of the vehicle seat as viewed from the vehicle outer side. In each figure, the seat back S1 of the seat body S of the vehicle seat has a known reclining structure, and the reclining lock is set by rotating the reclining lever 1 provided on the outer surface of the seat body S backward. The seat back S1 released and spring-biased is tilted onto the seat cushion S2.

シートクッションS1の内側部下面には前後方向へ延びる板状の脚体2が設けられており、脚体2の前後端下部にはそれぞれ係合手段を構成する係合板21が設けられている。係合板21は図3に示すように、脚体2の下縁に上半部が固定されて下方へ突出し、その下端には下方へ開放する切欠き211が形成されている。切欠き211内には、車両フロアFの凹所F1(図1)内に逆U字形に突設されたストライカ3の頂部31が進入して、係合板21を介して脚体2を車両フロアF上に支持している。   A plate-like leg 2 extending in the front-rear direction is provided on the lower surface of the inner portion of the seat cushion S1, and engagement plates 21 constituting engagement means are provided at the lower parts of the front and rear ends of the leg 2, respectively. As shown in FIG. 3, the engaging plate 21 has an upper half fixed to the lower edge of the leg 2 and protrudes downward, and a lower end thereof is formed with a notch 211 that opens downward. The top 31 of the striker 3 protruding in an inverted U shape enters the recess F1 (FIG. 1) of the vehicle floor F into the notch 211, and the leg body 2 is connected to the vehicle floor via the engagement plate 21. Supports on F.

脚体2の後端に設けられた係合板21には図3に示すようなフック板22が設けられている。フック板22は係合板21の下端部板面に立設された軸体221に回動可能に取り付けられており、フック板22は略コ字形に成形された先端の一部223が上記切欠き211を横切って、上記ストライカ3の頂部31を包持している。これにより、脚体2が車両フロアFに結合される。フック板22の上方には規制板23が設けてある。   A hook plate 22 as shown in FIG. 3 is provided on the engagement plate 21 provided at the rear end of the leg 2. The hook plate 22 is rotatably attached to a shaft body 221 erected on the lower end plate surface of the engagement plate 21, and the hook plate 22 is formed in a substantially U-shaped part 223 at the tip thereof. Crossing 211, the top 31 of the striker 3 is held. As a result, the leg 2 is coupled to the vehicle floor F. A restriction plate 23 is provided above the hook plate 22.

規制板23はその基部が係合板21の板面に立設された軸体231に回動自在に支持されており、規制板23の下側面に形成されたL状凸部232が、上記フック板22の頂面に形成されたL状凹部222に係合して、ストライカ頂部31の包持状態を解消する方向へフック板22が回動するのを規制している。なお、脚体2の上端はシートクッションS2の下面にヒンジ結合されて、シートクッションS2の下面に向けて回動可能であり、脚体2の後端面中間位置には、シートクッションS2の外側部から延びるリンクアーム24(図1)の一端が連結されている。   The base of the restriction plate 23 is rotatably supported by a shaft body 231 erected on the plate surface of the engagement plate 21, and an L-shaped convex portion 232 formed on the lower side surface of the restriction plate 23 includes the hook. Engaging with an L-shaped recess 222 formed on the top surface of the plate 22, the hook plate 22 is restricted from rotating in a direction to cancel the holding state of the striker top portion 31. The upper end of the leg 2 is hinged to the lower surface of the seat cushion S2, and can be rotated toward the lower surface of the seat cushion S2. One end of a link arm 24 (FIG. 1) that extends from is connected.

シートクッションS2のフレーム後端に固定されたロアパネル41には、図4に示すように、シートバックS1のフレーム下端に固定されたアッパパネル42が、軸体43回りに回動自在に結合されており、既述のリクライニング機構のロックを解除すると、ロアパネル41に対してアッパパネル42が相対回動してシートバックS1を傾動させることができる。アッパパネル42にはこれと一体に回転する操作アーム44が設けてあり、シートクッションS2上へのシートバックS1の傾倒に伴う操作アーム44先端の移動軌跡中に、第1受動アーム51の上端に設けたピン体511が位置している。   As shown in FIG. 4, an upper panel 42 fixed to the lower end of the frame of the seat back S1 is coupled to the lower panel 41 fixed to the rear end of the seat cushion S2 so as to be rotatable around the shaft body 43. When the above-described reclining mechanism is unlocked, the upper panel 42 can be rotated relative to the lower panel 41 to tilt the seat back S1. The upper panel 42 is provided with an operation arm 44 that rotates integrally therewith, and is provided at the upper end of the first passive arm 51 in the movement locus of the tip of the operation arm 44 accompanying the tilt of the seat back S1 on the seat cushion S2. The pin body 511 is located.

第1受動アーム51はロアパネル41上に立設した軸体52に中間部が支持されて回動自在となっており、その下端に設けたピン体512が第2受動アーム53の長穴状の係合穴531内に挿入されている。第2受動アーム53は上辺中央が上記軸体52に回動自在に支持され、その一端には操作ワイヤ54が結合されている。操作ワイヤ54は下方へ延びて、脚体2の後端に設けた係合板21(図3)に付設した上記規制板23の先端に結合されている。なお、第2受動アーム53はロアプレート41との間に架設したコイルバネ45によって軸体52を中心にして図4の反時計方向へ回動付勢されている。   The first passive arm 51 is pivotally supported by a shaft body 52 erected on the lower panel 41, and a pin body 512 provided at the lower end of the first passive arm 51 is shaped like an elongated hole of the second passive arm 53. It is inserted into the engagement hole 531. The center of the upper side of the second passive arm 53 is rotatably supported by the shaft body 52, and an operation wire 54 is coupled to one end thereof. The operation wire 54 extends downward and is coupled to the tip of the restriction plate 23 attached to the engagement plate 21 (FIG. 3) provided at the rear end of the leg 2. The second passive arm 53 is urged to rotate counterclockwise in FIG. 4 about the shaft body 52 by a coil spring 45 installed between the second passive arm 53 and the lower plate 41.

シートクッションS2の外側面は、ホイールハウスWH上に設けられて車両前後方向へ延びる軸体61(図2)に支持されて、これを中心に側方へ跳ね上げ回動可能となっており、軸体61の周囲には、シートクッションS2(すなわちシート本体S)を当該軸体61を中心に跳ね上げ方向へ付勢するコイルバネ62が設けられている。   The outer side surface of the seat cushion S2 is supported on a shaft body 61 (FIG. 2) provided on the wheel house WH and extending in the vehicle front-rear direction, and can be turned upside-down around this. A coil spring 62 is provided around the shaft body 61 to urge the seat cushion S2 (that is, the seat main body S) in the springing direction about the shaft body 61.

このような構造の車両用シートにおいて、シート本体Sを収納する場合には、リクライニングレバー1を後方へ回動操作してリクライニングロックを解除すると、シートバックS1がバネ付勢力でシートクッションS2上に傾倒される(図1、図2の鎖線)。これに伴い、操作アーム44が図4の白矢印方向へ旋回してピン体511に当接して第1受動アーム51を軸体52を中心に図4の時計方向へ回動させる。これにより、ピン体512が係合する第2受動アーム53も同方向へ回動させられ、操作ワイヤ54が引かれて規制板23(図3)が上方へ回動させられて、フック板22との係合が解消され、回転規制状態が解除される。フック板22の回転規制が解除されると、シート本体Sはコイルバネ62によって跳ね上げ方向へ付勢されているから、ストライカ31の包持状態を解消するようにフック板22が回転させられて、シート本体Sは側方へ跳ね上げられ(横跳ね上げ)収納される(図5)。この際、脚体2はリンクアーム24によって、起立姿勢となったシートクッションS2の底面(車両内方を向いた面)に沿う位置へ折り畳まれる。   In the vehicle seat having such a structure, when the seat main body S is stored, when the reclining lever 1 is rotated backward to release the reclining lock, the seat back S1 is placed on the seat cushion S2 by a spring biasing force. It is tilted (dashed line in FIGS. 1 and 2). Accordingly, the operation arm 44 turns in the direction of the white arrow in FIG. 4 and abuts on the pin body 511 to rotate the first passive arm 51 about the shaft body 52 in the clockwise direction in FIG. As a result, the second passive arm 53 with which the pin body 512 engages is also rotated in the same direction, the operation wire 54 is pulled, and the regulating plate 23 (FIG. 3) is rotated upward, and the hook plate 22 is rotated. And the rotation restriction state is released. When the rotation restriction of the hook plate 22 is released, the seat body S is biased in the flip-up direction by the coil spring 62, so the hook plate 22 is rotated so as to cancel the holding state of the striker 31, The seat body S is flipped up sideways (side up) and stored (FIG. 5). At this time, the leg body 2 is folded by the link arm 24 to a position along the bottom surface of the seat cushion S2 in the standing posture (the surface facing the inside of the vehicle).

なお、上記実施形態におけるようにシート本体の側面にリクライニングレバーを設けるのに代えて、図6に示すようにシート後方へ引き出し操作するような構造のリクライニングレバー7をシートクッションS2の後端面に設けるようにしても良い。これによれば、シート本体Sの跳ね上げ収納の操作をよりスムーズに行うことができる。   Instead of providing the reclining lever on the side surface of the seat body as in the above-described embodiment, a reclining lever 7 having a structure for pulling out the seat rearward as shown in FIG. 6 is provided on the rear end surface of the seat cushion S2. You may do it. According to this, the operation of raising and storing the sheet main body S can be performed more smoothly.
