Description
本発明は、車両のシート収納構造に関する。 The present invention relates to a vehicle seat storage structure.
従来から、シートバックをシートクッションに重ねた状態で反転させ、シートバック及びシートクッションを車両のフロアに形成した凹部に収納するシート構造が知られている。このようなシート構造において、シートが着席可能な上向き状態にあるときに、シートクッションの下側にボードを設け、ボードの後端とシートクッションの裏面とを回転可能に接続することで、シートを収納した際にボードを、フロアとシートクッションの裏面との間で略水平方向に展開させている（特許文献１参照）。 2. Description of the Related Art Conventionally, a seat structure is known in which a seat back is stacked on a seat cushion and then inverted, and the seat back and seat cushion are stored in a recess formed in the floor of a vehicle. In such a seat structure, when the seat is in the upward position for seating, a board is provided below the seat cushion, and the rear end of the board and the back surface of the seat cushion are rotatably connected. When stored, the board is expanded in a substantially horizontal direction between the floor and the back surface of the seat cushion (see Patent Document 1).
ところで、車室内空間を大きく確保する観点から、シートクッションの上面とルーフとの距離は大きくとることが望ましい。そのためには、シートクッションを薄くするか、シート下のフロアの高さを低くする必要がある。シートクッションを薄くした場合、座り心地が悪化し、シート下のフロアの高さを低くした場合、凹部の深さが相対的に浅くなり、シート収納時にシートの下面がフロアより上方に大きく突出することとなり、ボードが大きく傾斜することとなる。
また、上向き状態にあるシートの下側にボードが見えるため、見映えも悪い。
本発明は、上記事情に鑑みなされたものであり、見映えを向上させるとともにシート収納時のボードを水平状態に近づけることができる車両のシート収納構造を提供することを目的とする。
Incidentally, from the viewpoint of ensuring a large interior space, it is desirable to provide a large distance between the top surface of the seat cushion and the roof. To achieve this, it is necessary to make the seat cushion thinner or lower the height of the floor under the seat. If the seat cushion is made thinner, seating comfort deteriorates, and if the height of the floor under the seat is lowered, the depth of the recess becomes relatively shallow, causing the bottom surface of the seat to protrude significantly above the floor when the seat is stowed. This causes the board to tilt significantly.
In addition, the board is visible under the sheet that is facing up, which makes it look bad.
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a seat storage structure for a vehicle that improves the appearance and allows the board to be brought close to a horizontal state when the seat is stored.
本発明に係る車両のシート収納構造は、車両のフロアに設けられた下方に凹む収納部と、前記収納部の前方に乗員が着座可能な使用状態で配置されたシートと、を備え、前記シートが、シートバックをシートクッションに重ねるように折り畳まれた状態で前記シートクッションの後部において車幅方向に延びる回転軸を中心に後方に反転されることで前記収納部に収納される収納状態となる車両のシート収納構造において、前記使用状態における前記シートの前記シートクッションと前記フロアとの間にボードが設けられ、前記ボードの後端部は、前記使用状態における前記シートの前記回転軸よりも後方において前記シートクッションの裏面に回転可能に連結され、前記シートの前記使用状態において前記シートクッションの下方に位置する前記フロアの前端部に、上方に突出するとともに車幅方向に延びる突出部が設けられ、前記シートの使用状態において、前記ボードの前端部は前記突出部の上面よりも下方において前記突出部よりも後方に位置し、前記シートを前記収納部に収納した収納状態において、前記ボードの前端部は前記突出部の上面に載る、ことを特徴とする。 A vehicle seat storage structure according to the present invention includes a storage section provided in a floor of a vehicle and recessed downward, and a seat disposed in front of the storage section in a used state in which an occupant can sit, and the seat However, when the seat back is folded so as to overlap the seat cushion, the seat back is flipped backwards around a rotation axis extending in the vehicle width direction at the rear of the seat cushion, so that the seat back is stored in the storage section. In the vehicle seat storage structure, a board is provided between the seat cushion of the seat and the floor in the use state, and a rear end portion of the board is located behind the rotation axis of the seat in the use state. A protrusion that is rotatably connected to the back surface of the seat cushion and that protrudes upward and extends in the vehicle width direction is provided at the front end of the floor that is located below the seat cushion when the seat is in use. , when the seat is in use, the front end of the board is located below the upper surface of the protrusion and behind the protrusion, and when the seat is stored in the storage section, the front end of the board is The portion rests on the upper surface of the protrusion.
この車両のシート収納構造によれば、シートが使用状態にあるときは、ボードが突出部の後に隠れるため、見栄えが良い。また、シート収納状態においては、突出部によりボードの前端部の高さを高くすることができるので、シート収納時のボードを水平状態に近づけることができる。 According to this vehicle seat storage structure, when the seat is in use, the board is hidden behind the protrusion, giving it a good appearance. Further, in the seat storage state, the height of the front end of the board can be increased by the protrusion, so that the board can be brought close to a horizontal state when the seat is stored.
前記シートを前記使用状態から前記収納状態に移動させる際、前記ボードの後端部は、前記フロアの上面の延長線よりも下方を通過してもよい。 When moving the seat from the use state to the storage state, the rear end of the board may pass below an extension of the upper surface of the floor.
この車両のシート収納構造によれば、シートを使用状態から収納状態へ移動させる際にボードの前端が上方に持ち上がるので、よりボードの前端を突出部の上面に乗せやすくすることができる。 According to this vehicle seat storage structure, since the front end of the board is lifted upward when the seat is moved from the usage state to the storage state, it is possible to more easily place the front end of the board on the upper surface of the protrusion.
前記突起部の後面は、上方かつ前方に傾斜させてもよい。 The rear surface of the protrusion may be inclined upwardly and forwardly.
この車両のシート収納構造によれば、ボードの前端部が突起部の後面に沿って上方に移動することができるので、よりボードの前端を突出部の上面に乗せやすくすることができる。 According to this vehicle seat storage structure, the front end of the board can move upward along the rear surface of the projection, making it easier to place the front end of the board on the upper surface of the projection.
図１に、本発明に係る車両のシート収納構造を備えた車両の一実施形態を示す。
図１に示すように、車両１のフロア２上には車両前方から前列シート３、中列シート４、後列シート５が設けられている。フロア２は、後述する使用状態における後列シート５の下方に位置する箇所においてその他の部分よりも高さが高くなる段差部２１と、段差部２１の車両後方で車両下方に凹み後列シート５を収納可能な収納部２２とを備える。
FIG. 1 shows an embodiment of a vehicle equipped with a vehicle seat storage structure according to the present invention.
As shown in FIG. 1, a front row seat 3, a middle row seat 4, and a back row seat 5 are provided on a floor 2 of a vehicle 1 from the front of the vehicle. The floor 2 includes a stepped portion 21 that is higher in height than other portions at a location located below the rear row seats 5 in a state of use, which will be described later, and a recessed area toward the bottom of the vehicle at the rear of the stepped portion 21 to accommodate the rear row seats 5. A storage section 22 is provided.
段差部２１は、中列シート４の後方で車両上方に立ち上がる起立部２１ａと、起立部２１ａの上端から車両後方に延びる上面部２１ｂとを有する。上面部２１ｂは、車両後方に向かうにつれて車両下方に傾斜している。また、上面部２１ｂの前端には、車両上方に突出するとともに車幅方向に延びる突出部２１ｃが設けられている。突出部２１ｃは、上面部２１ｂの車幅方向全域に亘って設けられている。突出部２１ｃの後面は、車両上方に向かうにつれて前方へ傾斜している。突出部２１ｃの突出量（高さ）は、その上面が収納部２２に収納した後列シート５のシートクッション５ａの裏面と同等となるように設定されている。 The step portion 21 includes an upright portion 21a that stands up above the vehicle behind the middle row seat 4, and an upper surface portion 21b that extends toward the rear of the vehicle from the upper end of the upright portion 21a. The upper surface portion 21b is inclined downwardly toward the rear of the vehicle. Furthermore, a protrusion 21c that protrudes upward from the vehicle and extends in the vehicle width direction is provided at the front end of the upper surface portion 21b. The protruding portion 21c is provided over the entire area of the upper surface portion 21b in the vehicle width direction. The rear surface of the protrusion 21c is inclined forward as it goes upward of the vehicle. The amount of protrusion (height) of the protruding portion 21c is set so that its upper surface is equivalent to the back surface of the seat cushion 5a of the rear row seat 5 stored in the storage portion 22.
本実施形態では、車両１はハイブリッド車両であり、使用状態における後列シート５の下方に位置するフロア２の上方に高電圧バッテリＶが配置されている。図２に示すように、段差部２１、すなわち起立部２１ａ、上面部２１ｂ及び突出部２１ｃは高電圧バッテリＶを覆うバッテリカバー２０により形成されている。バッテリカバー２０は、フロア２及び高電圧バッテリVに固定され、フロア２の一部を形成している。 In this embodiment, the vehicle 1 is a hybrid vehicle, and a high-voltage battery V is disposed above the floor 2 located below the rear row seats 5 when in use. As shown in FIG. 2, the stepped portion 21, that is, the upright portion 21a, the upper surface portion 21b, and the protruding portion 21c are formed by a battery cover 20 that covers the high voltage battery V. The battery cover 20 is fixed to the floor 2 and the high voltage battery V, and forms a part of the floor 2.
収納部２２は、段差部２１の上面部２１ｂよりも高さが低くなるように車両下方に凹んでいる。本実施形態では、後述するように折り畳んだ後列シート５を収納部２２に収納した際に、後列シート５が収納部２２から上方にはみ出している。 The storage portion 22 is recessed below the vehicle so that the height is lower than the upper surface portion 21b of the stepped portion 21. In this embodiment, when the folded rear row seats 5 are stored in the storage section 22 as described later, the rear row seats 5 protrude upward from the storage section 22.
後列シート５は、シートクッション５ａと、シートバック５ｂ、ヘッドレスト５ｃを有する。シートクッション５ａは、その後部に設けられた回転軸６によってフロア２に対して回転可能に支持されている。回転軸６は、段差部２１の上面部２１ｂの後端よりも車両後方及び上方において、その車幅方向両端部がフロア２に支持されている。シートバック５ｂは、シートクッション５ａの後部に回転可能に連結されている。ヘッドレスト５ｃは、シートバック５ｂの上部に回転可能に連結されている。 The back row seat 5 has a seat cushion 5a, a seat back 5b, and a headrest 5c. The seat cushion 5a is rotatably supported with respect to the floor 2 by a rotating shaft 6 provided at the rear thereof. The rotating shaft 6 is supported by the floor 2 at both end portions in the vehicle width direction behind and above the rear end of the upper surface portion 21 b of the stepped portion 21 . The seat back 5b is rotatably connected to the rear part of the seat cushion 5a. The headrest 5c is rotatably connected to the upper part of the seat back 5b.
後列シート５は、図３（ａ）に示すように乗員が着座可能な使用状態と、図３（ｂ）に示すように折り畳まれて収納部２２に収納された収納状態との間で移動可能となっている。後列シート５は、使用状態において、シートクッション５ａが段差部２１の車両上方に位置し、シートバック５ｂがシートクッション５ａの後部から車両上方に延び、ヘッドレスト５ｃがシートバック５ｂの上部から車両上方に延びている。使用状態から、ヘッドレスト５ｃをシートバック５ｂの前面に対向するように反転させ、シートバック５ｂをシートクッション５ａと対向するように車両前方に回動させることによって、シートクッション５ａ、シートバック５ｂ、ヘッドレスト５ｃが車両上下方向に重なった折り畳み状態となる。折り畳み状態で、シートクッション５ａを回転軸６を中心に車両後方に反転させることによって、後列シート５が収納部２２に収納された収納状態となる。 The rear row seat 5 is movable between an operating state in which a passenger can be seated, as shown in FIG. 3(a), and a storage state in which it is folded and stored in the storage section 22, as shown in FIG. 3(b). It becomes. When the rear row seat 5 is in use, the seat cushion 5a is located above the stepped portion 21 of the vehicle, the seat back 5b extends from the rear of the seat cushion 5a to the top of the vehicle, and the headrest 5c extends from the top of the seat back 5b to the top of the vehicle. It is extending. From the state of use, the seat cushion 5a, seat back 5b, and headrest are removed by inverting the headrest 5c so that it faces the front of the seat back 5b and rotating the seat back 5b toward the front of the vehicle so as to face the seat cushion 5a. 5c are in a folded state in which they overlap in the vertical direction of the vehicle. By inverting the seat cushion 5a toward the rear of the vehicle around the rotating shaft 6 in the folded state, the rear row seat 5 is placed in a storage state in which it is stored in the storage portion 22.
後列シート５の収納状態とすると、車両１の後部に荷室空間Ｓが形成される。回転軸６が上面部２１ｂの後端よりも車両上方に位置しているため、収納状態におけるシートクッション５ａの裏面は上面部２１ｂの後端よりも車両上方に位置しており、その間には段差が形成される。この段差を塞ぎ荷室空間Ｓの床面を段差がほとんどないフラットな状態にするため、後述するボード７が設けられる。 When the rear row seats 5 are in the stowed state, a luggage space S is formed at the rear of the vehicle 1. Since the rotating shaft 6 is located above the vehicle than the rear end of the upper surface portion 21b, the back surface of the seat cushion 5a in the stored state is located above the vehicle than the rear end of the upper surface portion 21b, and there is a step between them. is formed. In order to close this level difference and make the floor surface of the luggage compartment space S flat with almost no level difference, a board 7, which will be described later, is provided.
使用状態にある後列シート５のシートクッション５ａと段差部２１の上面部２１ｂとの間には、ボード７が設けられている。ボード７は、剛性のある板状部材で形成され、シートクッション５ａ裏面の後部に取り付けられる第１ボード７aと、第１ボード７aにヒンジ８を介して回転可能に連結される第２ボード７ｂとを有する。後列シート５の使用状態において、第２ボード７ｂの後端は第１ボード７ａの後端に連結され、第１ボード７ａと第２ボード７ｂが車両上下方向で重なった状態でシートクッション５ａと段差部２１の上面部２１ｂとの間に位置している。このような構成により、第２ボード７ｂの後端がヒンジ８を介してシートクッション５ａに回転可能に連結される。なお、請求項における「ボード」とは、第２ボード７ｂを指す。また、第２ボード７ｂの回転中心は、ヒンジ８の回転軸となる。 A board 7 is provided between the seat cushion 5a of the rear row seat 5 in use and the upper surface portion 21b of the stepped portion 21. The board 7 is formed of a rigid plate-like member and includes a first board 7a attached to the rear part of the back surface of the seat cushion 5a, and a second board 7b rotatably connected to the first board 7a via a hinge 8. has. When the rear row seat 5 is in use, the rear end of the second board 7b is connected to the rear end of the first board 7a, and when the first board 7a and the second board 7b overlap in the vertical direction of the vehicle, there is a difference in level from the seat cushion 5a. It is located between the upper surface portion 21b of the portion 21 and the upper surface portion 21b. With this configuration, the rear end of the second board 7b is rotatably connected to the seat cushion 5a via the hinge 8. Note that the "board" in the claims refers to the second board 7b. Further, the rotation center of the second board 7b becomes the rotation axis of the hinge 8.
後列シート５の使用状態において、第２ボード７ｂはその前部が段差部２１の上面部２１ｂに載るとともに、後端部がシートクッション５ａの裏面に連結されることで支持されている。この状態で、第２ボード７ｂの前端は突出部２１ｃよりも車両後方に位置している、すなわち、突出部２１ｃの上端よりも車両後方かつ下方に位置しているため、車両前方から見たとき、突出部２１ｃによって第２ボード７ｂが隠された状態となっている。また、後列シート５の収納状態においては、第２ボード７ｂの前端は突出部２１ｃの上面に載るとともに、後端部がシートクッション５ａの裏面に連結されることで支持される。すなわち、第２ボード７ｂはシートクッション５ａと突出部２１ｃとの間に延在し、シートクッション５ａの裏面とともに荷室空間Ｓの床面を形成する。 When the rear row seat 5 is in use, the second board 7b is supported by having its front portion resting on the upper surface portion 21b of the stepped portion 21 and its rear end portion being connected to the back surface of the seat cushion 5a. In this state, the front end of the second board 7b is located at the rear of the vehicle than the protrusion 21c, that is, the front end of the second board 7b is located at the rear and lower part of the vehicle than the upper end of the protrusion 21c, so when viewed from the front of the vehicle. , the second board 7b is hidden by the protrusion 21c. In addition, when the rear row seat 5 is in the stored state, the front end of the second board 7b rests on the upper surface of the protrusion 21c, and the rear end is supported by being connected to the back surface of the seat cushion 5a. That is, the second board 7b extends between the seat cushion 5a and the protrusion 21c, and forms the floor surface of the cargo space S together with the back surface of the seat cushion 5a.
以上のように、後列シート５を使用状態から収納状態に移動させると、第２ボード７ｂの前端部は車両前方かつ上方に移動する。このように第２ボード７ｂを移動させるための構造の一例を説明する。 As described above, when the rear seat 5 is moved from the used state to the stowed state, the front end of the second board 7b moves forward and upward of the vehicle. An example of a structure for moving the second board 7b in this manner will be described.
本実施形態では、図４に示すように、ヒンジ８（より正確にはヒンジ８の回転軸であり、ヒンジ８の第１ボード７aと第２ボード７ｂの間に位置する箇所）が後列シート５の使用状態において回転軸６（より正確には回転軸６によるシートクッション５ａの回転中心Ｇ。以下、「回転軸６」との記載は「回転中心Ｇ」を指すものとする。）よりも車両後方に位置している。このようにすることにより、後列シート５を収納状態としたときに、ヒンジ８が回転軸６よりも車両前方に移動するため、第２ボード７ｂの前端部が車両前方に移動する。このとき、図５に示すように、ヒンジ８（すなわち第２ボード７ｂの後端部）が段差部２１の上面部２１ｂの車両後方への延長面Ｌ１よりも車両下方を通過すると、第２ボード７ｂの前端は車両上方へ持ち上がる。すなわち、回転軸６とヒンジ８とを結ぶ線Ｌ２の長さが、回転軸６から上面部２１ｂの延長面Ｌ１までの距離よりも長くなるように設定することにより、少なくとも回転軸６とヒンジ８とを結ぶ線Ｌ２が回転軸６から上面部２１ｂの延長面Ｌ１に対して垂直になるようなシートクッション５ａの回転状態において、第２ボード７ｂの後端部が段差部２１の上面部２１ｂの延長面Ｌ１よりも車両下方を通過するため、第２ボード７ｂが、上面部２１ｂの後端と接する箇所を中心として、後端部が車両下方に、前端部が車両上方に移動するように回転する。これにより、後列シート５の収納状態において、第２ボード７ｂの前端部が突出部２１ｃの上面に、より確実に載るようにすることができる。 In this embodiment, as shown in FIG. In the usage state of It is located at the rear. By doing so, when the rear row seats 5 are placed in the stowed state, the hinge 8 moves further forward of the vehicle than the rotating shaft 6, so that the front end of the second board 7b moves forward of the vehicle. At this time, as shown in FIG. 5, when the hinge 8 (that is, the rear end portion of the second board 7b) passes below the vehicle than the extending surface L1 of the upper surface portion 21b of the stepped portion 21 toward the rear of the vehicle, the second board The front end of 7b is lifted up above the vehicle. That is, by setting the length of the line L2 connecting the rotating shaft 6 and the hinge 8 to be longer than the distance from the rotating shaft 6 to the extension surface L1 of the upper surface portion 21b, at least the rotating shaft 6 and the hinge 8 In a rotating state of the seat cushion 5a such that the line L2 connecting the rotation axis 6 is perpendicular to the extension surface L1 of the upper surface portion 21b, the rear end of the second board 7b is connected to the upper surface portion 21b of the step portion 21. In order to pass below the vehicle than the extension surface L1, the second board 7b rotates around the point where it contacts the rear end of the upper surface portion 21b so that the rear end moves below the vehicle and the front end moves above the vehicle. do. This allows the front end of the second board 7b to rest more reliably on the upper surface of the protrusion 21c when the rear row seats 5 are in the stored state.
なお、このとき第２ボード７ｂの前端が突出部２１ｃの上端よりも車両上方まで移動するように回転軸６とヒンジ８とを結ぶ線Ｌ２の長さを設定するとよい。図６に示すように、第２ボード７ｂの前端が突出部２１ｃの上面後端に至るシートクッション５ａの回転状態において、第２ボード７ｂの前端と上面部２１ｂとの距離ｘ２は、第２ボード７ｂ前端から上面部２１ｂ後端までの長さｙ２から第２ボード７ｂ後端から上面部２１ｂ後端までの長さｙ１を除算した値にヒンジ８と段差部２１の上面部２１ｂの延長面Ｌ１との距離ｘ１を積算した値となる。この関係から求められる第２ボード７ｂの前端と上面部２１ｂとの距離ｘ２が突出部２１ｃの上面部２１ｂからの突出量以上となるように設定することで、後列シート５を収納状態まで移動させる際に、第２ボード７ｂの前端部が突出部２１ｃの上面に、より確実に載るようにすることができる。 In addition, at this time, it is preferable to set the length of the line L2 connecting the rotating shaft 6 and the hinge 8 so that the front end of the second board 7b moves further above the vehicle than the upper end of the protrusion 21c. As shown in FIG. 6, when the seat cushion 5a is rotated so that the front end of the second board 7b reaches the rear end of the upper surface of the protrusion 21c, the distance x2 between the front end of the second board 7b and the upper surface 21b is The extension surface L1 of the upper surface part 21b of the hinge 8 and the stepped part 21 is calculated by dividing the length y2 from the front end of the second board 7b to the rear end of the upper surface part 21b by the length y1 from the rear end of the second board 7b to the rear end of the upper surface part 21b. This is the value obtained by integrating the distance x1 between By setting the distance x2 between the front end of the second board 7b and the upper surface portion 21b, which is determined from this relationship, to be equal to or greater than the amount of protrusion of the protruding portion 21c from the upper surface portion 21b, the rear row seat 5 is moved to the stowed state. At this time, the front end of the second board 7b can be placed on the upper surface of the protrusion 21c more reliably.
なお、ヒンジ８の位置は、シートクッション５ａ裏面の後端よりも車両前方に設けるのが良い。このようにすることによって、後列シート５を収納状態としたときに、第２ボード７ｂの後端がシートクッション５ａ裏面後部に載るため、第２ボード７ｂをより強固に支持することができる。 Note that the hinge 8 is preferably located further forward of the vehicle than the rear end of the back surface of the seat cushion 5a. By doing so, when the rear row seat 5 is in the stowed state, the rear end of the second board 7b rests on the rear rear surface of the seat cushion 5a, so that the second board 7b can be supported more firmly.
上記実施形態によれば、段差部２１の上面部２１ｂに突出部２１ｃを設け、後列シート５の使用状態においては、第２ボード７ｂがシートクッション５ａと上面部２１ｂとの間に位置するとともに、その前端が突出部２１ｃの上面よりも車両下方かつ後方に位置するため、後列シート５の使用状態において第２ボード７ｂが視認され難くなる。なお、このとき突出部２１ｃの後面とシートクッション５ａの前面とが隣接するようにすることで、より確実に後列シート５の使用状態において第２ボード７ｂが視認されないようにすることができる。また、後列シート５の収納状態においては、第２ボード７ｂの前端部が突出部２１ｃの上面に載るため、後列シート５収納状態における第２ボード７ｂ前端部の高さを高くすることができる。 According to the above embodiment, the protrusion 21c is provided on the upper surface 21b of the stepped portion 21, and when the rear row seat 5 is in use, the second board 7b is located between the seat cushion 5a and the upper surface 21b, and Since the front end thereof is located below and rearward of the vehicle than the upper surface of the protruding portion 21c, the second board 7b is difficult to be visually recognized when the rear row seat 5 is in use. At this time, by making the rear surface of the protruding portion 21c and the front surface of the seat cushion 5a adjacent to each other, it is possible to more reliably prevent the second board 7b from being visually recognized when the rear row seat 5 is in use. Furthermore, when the rear row seats 5 are in the stowed state, the front end of the second board 7b rests on the upper surface of the protrusion 21c, so that the height of the front end of the second board 7b when the back row seats 5 are stowed is increased.
後列シート５の高さを下げて車室空間を広くするためには、段差部２１の上面部２１ｂの高さを下げればよい。しかし、上面部２１ｂの高さを下げると、収納部２２の深さが浅くなってしまい、収納状態における後列シート５が収納部２２から車両上方にはみ出してしまう。このような状態では、後列シート５収納状態における第２ボード７ｂが車両前方かつ下方に大きく傾斜してしまい、荷室空間Ｓの利便性が低下する。 In order to lower the height of the rear row seat 5 and widen the vehicle interior space, the height of the upper surface portion 21b of the stepped portion 21 may be lowered. However, if the height of the upper surface portion 21b is lowered, the depth of the storage portion 22 becomes shallower, and the rear row seat 5 in the stored state protrudes from the storage portion 22 toward the top of the vehicle. In such a state, the second board 7b in the stowed state of the rear row seats 5 will tilt significantly toward the front of the vehicle and downward, reducing the convenience of the cargo space S.
後列シート５収納状態において、第２ボード７ｂの前端部を突出部２１ｃの上面に載せて、第２ボード７ｂ前端部の高さを高くすることで、第２ボード７ｂの傾斜を小さくすることができるので、荷室空間Ｓの利便性が向上する。 When the rear row seats 5 are in the stowed state, the front end of the second board 7b is placed on the top surface of the protrusion 21c to increase the height of the front end of the second board 7b, thereby reducing the inclination of the second board 7b. Therefore, the convenience of the luggage compartment space S is improved.
また、上記実施形態によれば、後列シート５使用状態において、ヒンジ８を回転軸６よりも車両後方に設け、第２ボード７ｂの後端部を回転軸６よりも車両後方でシートクッション５ａと連結することにより、後列シート５を収納状態に移動したときに第２ボード７ｂが車両前方に移動するため、第２ボード７ｂの前端部をより確実に突出部２１ｃの上面に載せることができる。 Further, according to the above embodiment, when the rear row seat 5 is in use, the hinge 8 is provided behind the rotating shaft 6 in the vehicle, and the rear end portion of the second board 7b is connected to the seat cushion 5a behind the rotating shaft 6 in the vehicle. By connecting, the second board 7b moves toward the front of the vehicle when the rear row seat 5 is moved to the stowed state, so that the front end of the second board 7b can be more reliably placed on the upper surface of the protrusion 21c.
また、上記実施形態によれば、後列シート５の収納状態への移動の際に、第２ボード７ｂの後端部が段差部２１の上面部２１ｂの延長面Ｌ１よりも下方を通過するようにしたため、後列シート５の収納状態への移動の際に第２ボード７ｂの前端が持ち上がり、第２ボード７ｂの前端部をより確実に突出部２１ｃの上面に載せることができる。 Further, according to the above embodiment, when the rear row seats 5 are moved to the stowed state, the rear end portion of the second board 7b passes below the extension surface L1 of the upper surface portion 21b of the stepped portion 21. Therefore, the front end of the second board 7b is lifted up when the rear row seat 5 is moved to the stored state, and the front end of the second board 7b can be more reliably placed on the upper surface of the protrusion 21c.
また、上記実施形態によれば、段差部２１の突出部２１ｃの後面を車両上方かつ前方に傾斜させることによって、第２ボード７ｂが車両前方に移動したとき、第２ボード７ｂの前端が突出部２１ｃの後面に沿って車両上方かつ前方に移動するため、第２ボード７ｂの前端部をより確実に突出部２１ｃの上面に載せることができる。後列シート５の収納状態への移動の際に、第２ボード７ｂの後端部が段差部２１の上面部２１ｂの延長面Ｌ１よりも下方を通過するようにし、第２ボード７ｂの前端が持ち上げることで、第２ボード７ｂの前端部を突出部２１ｃの上面に載せる場合においても、突出部２１ｃの後面を車両上方かつ前方に傾斜させることによって、第２ボード７ｂの前端が持ち上がる際に第２ボード７ｂ前端と突出部２１ｃが干渉することを抑制することができ、より確実に第２ボード７ｂ前端部を突出部２１ｃの上面に載せることができる。 Further, according to the above embodiment, the rear surface of the protrusion 21c of the stepped portion 21 is inclined upward and forward of the vehicle, so that when the second board 7b moves forward of the vehicle, the front end of the second board 7b is tilted toward the protrusion. Since the second board 7b moves upward and forward of the vehicle along the rear surface of the second board 7b, the front end of the second board 7b can be more reliably placed on the upper surface of the protrusion 21c. When moving the rear row seat 5 to the stowed state, the rear end of the second board 7b passes below the extension surface L1 of the upper surface 21b of the stepped portion 21, and the front end of the second board 7b is lifted up. Therefore, even when the front end of the second board 7b is placed on the upper surface of the protrusion 21c, by tilting the rear surface of the protrusion 21c upward and forward of the vehicle, when the front end of the second board 7b is lifted, the second Interference between the front end of the board 7b and the protrusion 21c can be suppressed, and the front end of the second board 7b can be placed on the upper surface of the protrusion 21c more reliably.
