Thereby, the restriction member 32 in the restriction posture stops the entry of the small luggage between the rear portion of the seat portion 2 of the seat 1 in the first use position and the floor 12, and the seat 6 (see FIG. 1). Even if a seated occupant tries to put his / her foot between the rear portion of the seat 2 of the seat 1 in the first use position and the floor 12, the seat is stopped by the restricting member 32.

次に図５及び図６に示す状態において、操作レバー３０を上方に操作すると、ワイヤ３１が操作レバー３０に引き操作されて、操作部材２８が横軸芯Ｐ６周りに図６の紙面反時計方向に操作されてピン２６から下方に離れる。これにより、図５及び図６から図７に示すように、右及び左の前支持リンク２０と右及び左の後支持リンク２１とを、横軸芯Ｐ２，Ｐ３周りに後方に揺動させて第２姿勢に設定することができるのであり、シート１を第２使用位置に設定することができる。この場合に、右及び左の前支持リンク２０と右及び左の後支持リンク２１との後方への揺動に対して、ダンパー３４から抵抗が掛かるのであり、右及び左の前支持リンク２０と右及び左の後支持リンク２１とを後方にゆっくりと揺動させることができる。   Next, in the state shown in FIGS. 5 and 6, when the operation lever 30 is operated upward, the wire 31 is pulled by the operation lever 30, and the operation member 28 is rotated counterclockwise in FIG. 6 around the horizontal axis P6. To move downward from the pin 26. As a result, as shown in FIGS. 5 and 6 to 7, the right and left front support links 20 and the right and left rear support links 21 are swung rearward around the horizontal axes P2 and P3. The second posture can be set, and the seat 1 can be set at the second use position. In this case, resistance is applied from the damper 34 to the rearward swing of the right and left front support links 20 and the right and left rear support links 21, and the right and left front support links 20 The right and left rear support links 21 can be slowly swung backward.

図７に示す状態は、右及び左の前支持リンク２０と右及び左の後支持リンク２１とが後方に倒れた第２姿勢に設定された状態で、シート１が第２使用位置に設定された状態である。図５及び図６から図７に示すように、右及び左の前支持リンク２０と右及び左の後支持リンク２１とを後方に揺動させると、右及び左の後支持リンク２１の後方への揺動に伴って、操作板２７が第２支持部材２５に対して後方（図７の紙面右方）に移動し、ピン２６が操作板２７の長孔２７ａの前端（図７の紙面左端）に達する。   The state shown in FIG. 7 is a state in which the right and left front support links 20 and the right and left rear support links 21 are set to the second posture in which they are tilted backward, and the seat 1 is set to the second use position. It is in the state. As shown in FIGS. 5 and 6 to 7, when the right and left front support links 20 and the right and left rear support links 21 are swung rearward, the right and left rear support links 21 are moved rearward. The operation plate 27 moves rearward (to the right in FIG. 7) with respect to the second support member 25, and the pin 26 moves to the front end of the long hole 27a of the operation plate 27 (the left end in FIG. 7). ).

この後、図７に示すように、操作レバー３０を下方に操作すると、操作部材２８が横軸芯Ｐ６周りに図７の紙面時計方向に操作されてロッド２６の後側部（図７の紙面右側部）に接当し、操作板２７の長孔２７ａと操作部材２８とによりピン２６が挟み込まれた状態となって、シート１が第２使用位置に保持される（右及び左の前支持リンク２０と右及び左の後支持リンク２１とが後方に倒れた第２姿勢に保持される）。   Thereafter, as shown in FIG. 7, when the operation lever 30 is operated downward, the operation member 28 is operated around the horizontal axis P6 in the clockwise direction in FIG. 7, and the rear side portion of the rod 26 (the paper surface in FIG. 7). The sheet 26 is held in the second use position (right and left front support). The seat 26 is sandwiched between the long hole 27a of the operation plate 27 and the operation member 28. The link 20 and the right and left rear support links 21 are held in the second posture in which they are tilted backward.

図５及び図６から図７に示すように、右及び左の前支持リンク２０と右及び左の後支持リンク２１とを上方に向く第１姿勢から後方に倒れた第２姿勢に設定する場合、右及び左の後支持リンク２１が後方に揺動するのに伴って、規制部材３２が起立した規制姿勢から後方に倒れていき、規制部材３２の下部３２ａが上方に移動していくのであり（右及び左の後支持リンク２１が後方に揺動してフロア１２に接近しても、規制部材３２の下部３２ａが上方に移動してフロア１２に接触しないのであり）、右及び左の前支持リンク２０と右及び左の後支持リンク２１とが後方に倒れた第２姿勢に設定されると、規制部材３２も横向きの退避姿勢に設定される。   As shown in FIGS. 5 and 6 to 7, when the right and left front support links 20 and the right and left rear support links 21 are set from the first posture facing upward to the second posture tilted backward. As the right and left rear support links 21 swing backward, the regulating member 32 falls backward from the standing posture, and the lower portion 32a of the regulating member 32 moves upward. (Even if the right and left rear support links 21 swing rearward and approach the floor 12, the lower portion 32a of the regulating member 32 moves upward and does not contact the floor 12). When the support link 20 and the right and left rear support links 21 are set to the second posture in which the support link 20 is tilted rearward, the regulating member 32 is also set to the sideways retracted posture.

この場合、図５及び図６に示すように、規制姿勢の規制部材３２によって、第１使用位置のシート１の座部２の後部とフロア１２との間への小荷物の入り込みが止められる点、並び、シート６（図１参照）に着座する乗員が第１使用位置のシート１の座部２の後部とフロア１２との間に足を入れようとしても規制部材３２によって止められる点により、図７に示すように、シート１を第２使用位置に設定しても、シート１の座部２（カバー３８）によって小荷物を押しつぶしてしまうようなことがないのであり、シート１の座部２（カバー３８）によってシート６（図１参照）に着座する乗員の足を上から押してしまうようなことがない。   In this case, as shown in FIGS. 5 and 6, the restriction member 32 in the restriction posture prevents the small luggage from entering between the rear portion of the seat portion 2 of the seat 1 in the first use position and the floor 12. , By the fact that the occupant seated on the seat 6 (see FIG. 1) tries to put his foot between the rear portion of the seat portion 2 of the seat 1 in the first use position and the floor 12, it is stopped by the restriction member 32, As shown in FIG. 7, even if the seat 1 is set to the second use position, the small portion is not crushed by the seat portion 2 (cover 38) of the seat 1. 2 (cover 38) does not push the foot of the passenger sitting on the seat 6 (see FIG. 1) from above.

図５及び図６から図７に示すように、右及び左の前支持リンク２０と右及び左の後支持リンク２１とを上方に向く第１姿勢から後方に倒れた第２姿勢に設定すると、右及び左の前支持リンク２０と右及び左の後支持リンク２１とが後方に揺動する点、並びに、右及び左の前支持リンク２０よりも右及び左の後支持リンク２１が大きく後方に揺動する点により、第１使用位置にシート１に対して第２使用位置のシート１が後方の下方に位置し、第２使用位置のシート１の座部２が少し前上がり姿勢となる。このようにシート１を第２使用位置に設定した後に、図２に示すようにシート１の背もたれ部３を後方に倒すことにより、乗員が安楽な姿勢でシート１に着座することができる。   As shown in FIGS. 5 and 6 to 7, when the right and left front support links 20 and the right and left rear support links 21 are set from the first position facing upward to the second position tilted backward, The right and left front support links 20 and the right and left rear support links 21 swing rearward, and the right and left rear support links 21 are larger rearward than the right and left front support links 20. Due to the swinging point, the seat 1 at the second use position is positioned rearward and downward with respect to the seat 1 at the first use position, and the seat portion 2 of the seat 1 at the second use position assumes a slightly raised position. Thus, after setting the seat 1 to the second use position, the occupant can sit on the seat 1 in an easy posture by tilting the backrest portion 3 of the seat 1 backward as shown in FIG.

図１に示すように、シート１と同様にシート６の座部７も前支持リンク３５及び後支持リンク３６によって支持されており、シート６の座部７を使用位置（図１参照）及び前方下方の格納位置（図３参照）に設定することができるのであり、使用位置においてシート６に乗員が着座する。これにより、図３に示すように、シート１を第２使用位置に設定した後、シート１の背もたれ部３を前方に倒し、次にシート６のヘッドレスト９を取り外してシート６の座部７を格納位置に設定し、シート６の背もたれ部８を前方に倒す。このような操作を行うと、シート１の背もたれ部３の裏部、シート６の背もたれ部８の裏部及び荷物室のフロア３７が略同じ高さとなり、フラットな面を得ることができる。   As shown in FIG. 1, the seat 7 of the seat 6 is also supported by the front support link 35 and the rear support link 36 in the same manner as the seat 1, and the seat 7 of the seat 6 is used at the use position (see FIG. 1) and the front. The lower storage position (see FIG. 3) can be set, and the occupant sits on the seat 6 at the use position. Thus, as shown in FIG. 3, after the seat 1 is set to the second use position, the backrest portion 3 of the seat 1 is tilted forward, the headrest 9 of the seat 6 is then removed, and the seat portion 7 of the seat 6 is removed. The seat is set in the retracted position, and the backrest 8 of the seat 6 is tilted forward. When such an operation is performed, the back part of the backrest part 3 of the seat 1, the back part of the backrest part 8 of the seat 6, and the floor 37 of the luggage compartment have substantially the same height, and a flat surface can be obtained.
