特許文献１に示されるサブマリン防止のクロスメンバは、板金製の直方体形状の中央ブラケットが車幅方向中央部分に、また板金製の略四角錐状に形成された側部ブラケットが、中央ブラケットの車幅方向両側に、それぞれリヤフロアパネルの上面に溶接によって取り付けられている構造である。
また、特許文献２に示されるサブマリン防止のクロスメンバは、リヤシートクッションの前方部分に対応するリヤフロアの部分が、上方に突出して車幅方向に延在して形成される構造である。
これら特許文献１、２の何れもサブマリン現象を防止する構造が大型化し、重量増大化を招きやすい。
また、特許文献３においては、硬質の発泡樹脂材からなる前滑り防止部材をシートクッション本体内に内蔵させる構造であるため、シートベルトを装着した乗員が、腰ベルトからすり抜ける動きを抑制する上で、適正な抑制力を発揮できる強度が得られるか問題である。 The cross marine-preventing cross member disclosed in Patent Document 1 has a sheet metal rectangular parallelepiped central bracket at the center in the vehicle width direction, and a sheet metal side bracket formed in a substantially square pyramid shape. This structure is attached to the upper surface of the rear floor panel by welding on both sides in the width direction.
In addition, the submarine-preventing cross member disclosed in Patent Document 2 has a structure in which a portion of the rear floor corresponding to the front portion of the rear seat cushion protrudes upward and extends in the vehicle width direction.
In any of these Patent Documents 1 and 2, the structure for preventing the submarine phenomenon is enlarged, and the weight is likely to increase.
Moreover, in patent document 3, since it is the structure where the front slip prevention member which consists of a hard foaming resin material is incorporated in a seat cushion main body, in order to suppress the passenger | crew with which the seatbelt mounted | worn slips from a waist belt, However, it is a problem whether the strength capable of exhibiting an appropriate suppression force is obtained.

そこで、これら技術的課題に鑑み、本発明の少なくとも一つの実施形態は、大型化及び重量増大化することなく、シートベルトを装着した乗員が、腰ベルトからすり抜けるサブマリン現象を抑制できる自動車のリヤシート支持構造を提供することを目的とする。   Accordingly, in view of these technical problems, at least one embodiment of the present invention is a vehicle rear seat support that can suppress a submarine phenomenon that a passenger wearing a seat belt slips through a waist belt without increasing the size and weight. The purpose is to provide a structure.

（１）本発明の少なくとも一実施形態に係る自動車のリヤシート支持構造は、車室内の床面を形成するフロントフロアパネルの後端から上方に立ち上がって車体後方に延びるリヤフロアパネルを備え、前記リヤフロアパネルの上面にリヤシートクッションが支持される自動車のリヤシート支持構造において、
前記リヤフロアパネルの前方部分に取り付けられ、前記リヤシートクッションの前方部分の内部に収容されるように配置されるリヤシートクロスメンバが設けられ、前記リヤシートクロスメンバは、パイプ部材によって形成され車幅方向に延在して設けられる本体部と、該本体部の左右両端から前記本体部のパイプ部材と連続して形成され所定の曲げ半径を有した曲げ部と、該曲げ部を介して前記本体部と直角方向に形成される左右の脚部と、前記左右の脚部のそれぞれの下端に設けられて前記リヤフロアパネル側への取付けを行う脚部取付けブラケットと、を備えることを特徴とする。 (1) A rear seat support structure for an automobile according to at least one embodiment of the present invention includes a rear floor panel that rises upward from a rear end of a front floor panel that forms a floor surface in a vehicle interior and extends rearward of the vehicle body, and the rear floor panel In the rear seat support structure of an automobile in which the rear seat cushion is supported on the upper surface of
A rear seat cross member is provided that is attached to the front portion of the rear floor panel and is disposed so as to be accommodated inside the front portion of the rear seat cushion. The rear seat cross member is formed by a pipe member and extends in the vehicle width direction. A main body portion provided at the same time, a bending portion having a predetermined bending radius formed continuously from the left and right ends of the main body portion with the pipe member of the main body portion, and perpendicular to the main body portion via the bending portion. Left and right leg portions formed in a direction, and leg portion mounting brackets provided at lower ends of the left and right leg portions, respectively, for mounting on the rear floor panel side.

前記構成（１）によれば、リヤシートクロスメンバは、パイプ部材によって形成されてリヤフロアパネルの上面に取付けられる構造であるので、板金による構造に比べて大型化及び重量増大化を抑えることができる。
しかも、本体部と脚部とは、所定の曲げ半径を有した曲げ部介して連続しているので、すなわち、パイプ部材の曲げ部を設けることによって、曲げ部におけるパイプ部材の曲げ加工による硬化による強度向上が得られる。その結果、乗員が前方へ移動する際に作用する荷重に対する本体部及び脚部の連結部分の強度を高めることができる。
従って、強度的にも、従来技術として知られている硬質の発泡樹脂材をシートクッション内に内蔵させる構造よりも向上できるため、乗員が腰ベルトからすり抜けるサブマリン現象を効果的に抑制できる。 According to the configuration (1), since the rear seat cross member is formed by a pipe member and is attached to the upper surface of the rear floor panel, it is possible to suppress an increase in size and weight compared to a structure using a sheet metal.
In addition, since the main body and the leg are continuous through a bending portion having a predetermined bending radius, that is, by providing a bending portion of the pipe member, the bending portion is cured by bending the pipe member. Strength improvement is obtained. As a result, the strength of the connecting portion of the main body portion and the leg portion against the load acting when the occupant moves forward can be increased.
Therefore, since the strength can be improved as compared with the structure in which the hard foamed resin material known as the prior art is built in the seat cushion, the submarine phenomenon that the occupant slips through the waist belt can be effectively suppressed.

（２）幾つかの実施形態では、前記構成（１）において、前記リヤシートクロスメンバの前記本体部と前記脚部とは、同一パイプ径のパイプ部材からなり、前記曲げ部を含めて前記本体部及び脚部を一体のパイプ部材によって形成されることを特徴とする。
前記構成（２）によれば、リヤシートクロスメンバの本体部と脚部とが、同一パイプ径のパイプ部材からなるとともに、一体のパイプ部材からなるため、溶接箇所がないためリヤシートクロスメンバの加工工数が低減できる。また、溶接箇所がないため、強度的にも有利である。 (2) In some embodiments, in the configuration (1), the main body portion and the leg portion of the rear seat cross member are pipe members having the same pipe diameter, and the main body portion includes the bent portion. And the leg portion is formed by an integral pipe member.
According to the configuration (2), since the main body portion and the leg portion of the rear seat cross member are made of a pipe member having the same pipe diameter and are made of an integral pipe member, there is no welded portion, so that the number of processing steps for the rear seat cross member is reduced. Can be reduced. Moreover, since there is no welding location, it is advantageous also in strength.

（３）幾つかの実施形態では、前記構成（１）又は（２）の構成において、前記脚部取付けブラケットは、上下方向に延設され前記脚部の下端部が接合される脚接合部と、リヤフロアパネル側へのボルト締結を行う締結部と、前記脚接合部の下端部分から前記締結部との間を連結するとともに、前記脚部の車体外側に傾斜して形成される傾斜部と、を有していることを特徴とする。   (3) In some embodiments, in the configuration of the configuration (1) or (2), the leg portion mounting bracket includes a leg joint portion that extends in a vertical direction and is joined to a lower end portion of the leg portion. A fastening portion that performs bolt fastening to the rear floor panel side, and an inclined portion that is formed to be inclined to the outside of the vehicle body of the leg portion, while connecting between the fastening portion from a lower end portion of the leg joint portion, It is characterized by having.

前記構成（３）によれば、脚部取付けブラケットは、接続部と、傾斜部と、締結部とを有しており、傾斜部は、接合部の下端から締結部との間を連結するとともに、脚部の車体外側に傾斜して形成されているので、脚部から脚部取付けブラケットに作用する荷重は、応力を集中させることなく、分散させることが可能である。
例えば、傾斜部がなく、接続部の下端の延長部分に締結部が設けられている構造の場合には、脚部から脚部取付けブラケットに作用する荷重に対して、脚部と脚部取付けブラケットとの連結部(曲げ部)に応力が集中し、強度上問題が生じやすい。 According to the configuration (3), the leg portion mounting bracket includes the connection portion, the inclined portion, and the fastening portion, and the inclined portion connects the lower end of the joint portion to the fastening portion. Since the leg is formed to be inclined to the outside of the vehicle body, the load acting on the leg mounting bracket from the leg can be dispersed without concentrating the stress.
For example, in the case of a structure in which there is no inclined part and a fastening part is provided at the lower end of the connection part, the leg part and the leg part mounting bracket against the load acting on the leg part mounting bracket from the leg part Stress concentrates on the connecting part (bending part) and the strength problem is likely to occur.

（４）幾つかの実施形態では、前記構成（３）の構成において、前記傾斜部の車両側面視における幅は、下方に向かうにしたがって増大することを特徴とする。
前記構成（４）によれば、傾斜部の車両側面視における幅は、すなわち、車体前後の幅は、車体の下方に向かうにしたがって増大するため、脚部から脚部取付けブラケットに作用する荷重に対する脚部取付けブラケットに生じる応力は、リヤフロアパネルへのボルト締結を行う締結部位へ分散されて作用し、また、均等化させることが可能となる。 (4) In some embodiments, in the configuration of the configuration (3), the width of the inclined portion in a vehicle side view increases toward the lower side.
According to the configuration (4), the width of the inclined portion in the vehicle side view, that is, the width of the front and rear of the vehicle body increases toward the lower side of the vehicle body, so that the load acting on the leg mounting bracket from the leg portion is increased. The stress generated in the leg mounting bracket is distributed and acts on the fastening portion for fastening the bolt to the rear floor panel, and can be equalized.

（５）幾つかの実施形態では、前記構成（３）または（４）の構成において、前記脚接合部における溶接のための円弧状のビード形状部は、前記脚接合部から前記傾斜部及び前記締結部の開放端に至るまで連続して形成されることを特徴とする。
前記構成（５）によれば、脚接合部における溶接のための円弧状のビード形状部が、脚接合部から傾斜部及び締結部の開放端に至るまで連続して形成されるので、脚部取付けブラケットの剛性を向上でき強度を高めることができる。 (5) In some embodiments, in the configuration of the configuration (3) or (4), the arc-shaped bead-shaped portion for welding in the leg joint portion includes the inclined portion and the leg portion from the leg joint portion. It is characterized by being formed continuously up to the open end of the fastening portion.
According to the configuration (5), the arc-shaped bead-shaped portion for welding at the leg joint portion is continuously formed from the leg joint portion to the open end of the inclined portion and the fastening portion. The rigidity of the mounting bracket can be improved and the strength can be increased.

本発明の少なくとも一実施形態によれば、リヤシートクッションの前方部分の内部に設けられるリヤシートクロスメンバを大型化及び重量増大化することなく、シートベルトを装着した乗員が、腰ベルトからすり抜けるサブマリン現象を抑制できる。   According to at least one embodiment of the present invention, a submarine phenomenon in which a passenger wearing a seat belt slips through a waist belt without increasing the size and weight of a rear seat cross member provided in the front portion of the rear seat cushion. Can be suppressed.

The rear seat cross member 31 includes a main body portion 35 extending in the vehicle width direction, and left and right leg portions formed in a direction perpendicular to the main body portion 35 continuously from the left and right ends of the main body portion 35. 37, 37 and leg mounting brackets provided at the lower ends of the left and right leg portions 37, 37, respectively, for mounting the rear floor panel 7, the rear floor cross member 9, the rear side frame 11, and the like on the vehicle body members on the rear floor panel side. 39, 39.
Further, as shown in FIG. 3, a central bracket 41 is provided at a location that is attached to a substantially central portion of the main body portion 35 extending in the vehicle width direction and is located in the central portion of the seat cushion portion 15 in the vehicle width direction. Yes.

シートクッション凹部３３の内部に、これら本体部３５と、脚部３７と、脚部取付けブラケット３９と、中央ブラケット４１とが、収容されシートクッション部１５の外部からは視認し難くなっている。   The main body portion 35, the leg portion 37, the leg portion mounting bracket 39, and the central bracket 41 are accommodated inside the seat cushion recessed portion 33, and are hardly visible from the outside of the seat cushion portion 15.

リヤシートクロスメンバ３１は、鋼管製のパイプ部材によって形成されてリヤフロアパネル７、リヤフロアクロスメンバ９、リヤサイドフレーム１１等のリヤフロアパネル側の車体部材上面に取り付けられる構造であるので、従来の板金製によって形成されてリヤフロアパネル側の車体部材の上面に取り付けられる構造に比べて大型化及び重量増大化を抑制できる。   The rear seat cross member 31 is formed by a pipe member made of steel pipe and is attached to the upper surface of the vehicle body member on the rear floor panel side such as the rear floor panel 7, the rear floor cross member 9, the rear side frame 11, etc. Thus, an increase in size and weight can be suppressed as compared with a structure that is attached to the upper surface of the vehicle body member on the rear floor panel side.

さらに、本体部３５と脚部３７とは、同一パイプ径のパイプ部材からなり、所定の曲げ半径Ｒを有した曲げ部４３を介して連続している。本体部３５と左右の脚部３７、３７が全て連続した一体のパイプ部材から形成しても、また、図３に示すように、本体部３５と左右の脚部３７、３７とを溶接部４５によって溶接して連続構造としてもよい。
本体部３５と左右の脚部３７とを全て連続した一体のパイプ部材から形成すると、溶接箇所がないためリヤシートクロスメンバ３１の加工工数が低減できる。また、溶接箇所がないため、強度的にも有利である。 Further, the main body portion 35 and the leg portion 37 are made of a pipe member having the same pipe diameter, and are continuous via a bending portion 43 having a predetermined bending radius R. Even if the main body portion 35 and the left and right leg portions 37, 37 are all formed of a continuous pipe member, as shown in FIG. 3, the main body portion 35 and the left and right leg portions 37, 37 are connected to the welded portion 45. May be welded to form a continuous structure.
If the main body portion 35 and the left and right leg portions 37 are all formed from a continuous integral pipe member, the number of processing steps for the rear seat cross member 31 can be reduced because there are no welded portions. Moreover, since there is no welding location, it is advantageous also in strength.

リヤシートクロスメンバ３１の本体部３５と脚部３７とが、同一パイプ径のパイプ部材からなり、所定の曲げ半径を有した曲げ部４３を介して連続しているので、すなわち、パイプ部材に曲げ部４３を設けることによって、曲げ部４３におけるパイプ部材の曲げ加工による硬化が期待でき強度向上が得られる。
その結果、乗員が前方へ移動する際に作用する本体部３５への上下方向荷重及び前後方向荷重に対して、本体部３５及び脚部３７の連結部分の強度を高めることができる。
例えば、パイプ部材による曲げ部４３を介さずに、車幅方向に延びる本体部の端部を別部品、例えば板金製のブラケット等で支持する構造に比べて、本体部３５及び脚部３７の連結部分の強度を高めることができる。
従って、大型化及び重量増大化を抑制でき、しかも、強度的にも、硬質の発泡樹脂材をシートクッション内に内蔵させる構造よりも向上できるため、乗員が腰ベルトからすり抜けるサブマリン現象を効果的に抑制できる。 Since the main body portion 35 and the leg portion 37 of the rear seat cross member 31 are made of a pipe member having the same pipe diameter and are continuous via a bending portion 43 having a predetermined bending radius, that is, the bending portion is connected to the pipe member. By providing 43, hardening by the bending process of the pipe member in the bending part 43 can be expected, and the strength can be improved.
As a result, the strength of the connecting portion of the main body portion 35 and the leg portion 37 can be increased with respect to the vertical load and the longitudinal load on the main body portion 35 acting when the occupant moves forward.
For example, compared to a structure in which the end of the main body extending in the vehicle width direction is supported by another part, for example, a bracket made of sheet metal, without the bent portion 43 formed by a pipe member, the main body 35 and the leg 37 are connected. The strength of the part can be increased.
Therefore, it is possible to suppress an increase in size and weight and to improve the strength compared to a structure in which a hard foamed resin material is incorporated in the seat cushion, effectively preventing the submarine phenomenon that the occupant slips through the waist belt. Can be suppressed.

中央ブラケット４１と脚部３７との間の略中央部分には、シートクッション部１５を支持する左右のクッション支持ブラケット４７、４７が、本体部３５のパイプ部材に溶接接合されている。クッション支持ブラケット４７は、図３に示すように、車両前方側に突出した支持プレート４９に係合穴５１が形成された形状を有し、その係合穴５１に、シートクッション部１５の内部に埋設されているワイヤフレーム２９に取り付けられた係合ワイヤ５３を挿入してシートクッション部１５を固定するようになっている。
従って、シートクッション部１５を車体に取り付ける際には、リヤシートクロスメンバ３１が既にリヤフロアパネル側部材へ取り付けられており、その上に被せるようにしてシートクッション部１５を取り付けるとともに、係合ワイヤ５３をクッション支持ブラケット４７の係合穴５１に挿入して固定する。 Left and right cushion support brackets 47 and 47 that support the seat cushion portion 15 are welded to the pipe member of the main body portion 35 at a substantially central portion between the central bracket 41 and the leg portion 37. As shown in FIG. 3, the cushion support bracket 47 has a shape in which an engagement hole 51 is formed in a support plate 49 protruding toward the front side of the vehicle, and the engagement hole 51 is formed inside the seat cushion portion 15. The seat cushion portion 15 is fixed by inserting an engaging wire 53 attached to the embedded wire frame 29.
Therefore, when the seat cushion portion 15 is attached to the vehicle body, the rear seat cross member 31 is already attached to the rear floor panel side member, and the seat cushion portion 15 is attached so as to cover the member, and the engaging wire 53 is attached. It is inserted into the engagement hole 51 of the cushion support bracket 47 and fixed.

中央ブラケット４１は、車両前後方向に延びて配置され側面視が略三角形状に形成され、上端の上部支持部５４と、下端後方の中央後フランジ部５５と、下端前方の中央前フランジ部５７とを有し、上部支持部５４には本体部３５のパイプ部材が載置されるとともにパイプ部材を溶接固定している。また、中央後フランジ部５５にはリヤフロアパネル７への締結を行うボルト５６が貫通するボルト穴が形成され、中央前フランジ部５７にはリヤフロアクロスメンバ９の上面への締結を行うボルト５８が貫通するボルト穴が形成されている。   The central bracket 41 extends in the vehicle front-rear direction and is formed in a substantially triangular shape when viewed from the side. The upper support portion 54 at the upper end, the central rear flange portion 55 at the lower rear, and the central front flange portion 57 at the lower front. The pipe member of the main body portion 35 is placed on the upper support portion 54 and the pipe member is fixed by welding. Further, a bolt hole through which a bolt 56 for fastening to the rear floor panel 7 passes is formed in the center rear flange portion 55, and a bolt 58 for fastening to the upper surface of the rear floor cross member 9 passes through the center front flange portion 57. Bolt holes are formed.

脚部取付けブラケット３９は、左側用と右側用とがそれぞれ設けられ、車両外側からの側面視において、車両前後方向の形状は略同一形状を有している。脚部取付けブラケット３９は、上端部に、リヤシートクロスメンバ３１の脚部３７の下端部と溶接する上下方向に延在する脚接合部６０を有し、下端部前方に、リヤフロアクロスメンバ９の上面へのボルト６３による締結を行う脚前フランジ部（締結部）６５を有し、下端部後方に、リヤサイドフレーム１１の上面へのボルト締結を行う脚後フランジ部（締結部）６７を有している。   The leg mounting bracket 39 is provided for the left side and for the right side, respectively, and has a substantially identical shape in the vehicle front-rear direction when viewed from the side of the vehicle. The leg mounting bracket 39 has a leg joint 60 extending in the vertical direction welded to the lower end of the leg 37 of the rear seat cross member 31 at the upper end, and the upper surface of the rear floor cross member 9 in front of the lower end. A leg front flange part (fastening part) 65 for fastening with a bolt 63 to the rear side, and a leg rear flange part (fastening part) 67 for fastening bolts to the upper surface of the rear side frame 11 at the rear of the lower end part. Yes.

さらに、図４に示すように、脚部取付けブラケット３９は、脚部３７の軸線Ｌを含む車幅方向断面形状において、脚接合部６０の下端から下方向に延びて脚後フランジ部６７に至るように脚部３７の車体外側に傾斜して形成される傾斜部６９が形成されている。
図４の例では、脚接合部６０の下端位置ａから脚後フランジ部６７の接続位置ｂまで傾斜部６９が形成されている。傾斜部６９は曲線形状に形成されているが、直線形状に結ぶよう形成されていてもよい。
また、図４に示すように傾斜部６９の外側への傾斜長さＣは、車両正面視方向で脚部３７のハイプ径の１〜３倍に設けられるとよい。 Further, as shown in FIG. 4, the leg mounting bracket 39 extends downward from the lower end of the leg joint portion 60 and reaches the leg rear flange portion 67 in the vehicle width direction sectional shape including the axis L of the leg portion 37. In this way, an inclined portion 69 is formed which is inclined to the outside of the vehicle body of the leg portion 37.
In the example of FIG. 4, an inclined portion 69 is formed from the lower end position a of the leg joint portion 60 to the connection position b of the leg rear flange portion 67. The inclined portion 69 is formed in a curved shape, but may be formed so as to be tied in a linear shape.
Moreover, as shown in FIG. 4, the inclination length C to the outer side of the inclination part 69 is good to provide 1-3 times the hypo diameter of the leg part 37 in a vehicle front view direction.

このように、脚部取付けブラケット３９は、脚接合部６０と、傾斜部６９と、脚前フランジ部６５と、脚後フランジ部６７とを有し、傾斜部６９が、脚接合部６０の下端から脚前フランジ部６５及び脚後フランジ部６７との間をそれぞれ連結するとともに、車両正面視において傾斜部６９は、脚部３７の車体外側に傾斜して形成されているので、脚部３７から脚前フランジ部６５及び脚後フランジ部６７に作用する荷重に対して、応力を集中させることなく、分散させることが可能である。   As described above, the leg mounting bracket 39 includes the leg joint portion 60, the inclined portion 69, the front leg flange portion 65, and the rear leg flange portion 67, and the inclined portion 69 is the lower end of the leg joint portion 60. The leg front flange portion 65 and the leg rear flange portion 67 are connected to each other, and the inclined portion 69 is formed to be inclined to the outside of the vehicle body of the leg portion 37 when viewed from the front of the vehicle. The load acting on the front leg flange portion 65 and the rear leg flange portion 67 can be dispersed without concentrating stress.

例えば、傾斜部６９がなく、脚接合部６０の下端の延長部分にリヤフロアパネル等への締結部のフランジ部が設けられている場合には、締結部へ接続する箇所に応力集中が生じやすい。しかし、傾斜部６９が設けられ、所定の長さを有することで、傾斜部６９によって脚部３７から脚部取付けブラケット３９に作用する荷重に対して分散可能であり、応力集中を抑えることができる。   For example, when there is no inclined portion 69 and the flange portion of the fastening portion to the rear floor panel or the like is provided in the extended portion at the lower end of the leg joint portion 60, stress concentration is likely to occur at the location where the fastening portion is connected. However, since the inclined portion 69 is provided and has a predetermined length, it is possible to disperse the load acting on the leg mounting bracket 39 from the leg portion 37 by the inclined portion 69, and the stress concentration can be suppressed. .

さらに、傾斜部６９は、車体外側からの側面視における幅（車両前後方向長さ）は、下方に向かうにしたがって増大するように形成されている。図４のように脚接合部６０の下端ではＷ１の幅が、脚前フランジ部６５及び脚後フランジ部６７への連結部においてはＷ２まで拡幅した形状を有している。   Further, the inclined portion 69 is formed such that the width (length in the vehicle front-rear direction) in a side view from the outside of the vehicle body increases as it goes downward. As shown in FIG. 4, the width of W <b> 1 at the lower end of the leg joint portion 60 is widened to W <b> 2 at the connecting portion to the leg front flange portion 65 and the leg rear flange portion 67.

このように、車体外側からの側面視における幅（車両前後方向長さ）は、下方に向かうにしたがって増大するように形成されているので、脚部３７から脚部取付けブラケット３９に作用する荷重に対する脚部取付けブラケット３９に生じる応力は、リヤフロアパネル７側へのボルト締結を行う脚前フランジ部６５及び脚後フランジ部６７へ分散されて作用することができる。
以上のように、脚部取付けブラケット３９の傾斜部６９及び拡幅形状によって、脚部３７から脚部取付けブラケット３９に作用する荷重に対する脚部取付けブラケット３９に生じる応力を分散化して、さらに均等化させることが可能となる。 Thus, the width in the side view from the outside of the vehicle body (the length in the vehicle front-rear direction) is formed so as to increase downward, so that the load acting on the leg mounting bracket 39 from the leg 37 is not affected. The stress generated in the leg mounting bracket 39 can be distributed and act on the front leg flange portion 65 and the rear leg flange portion 67 that perform bolt fastening to the rear floor panel 7 side.
As described above, by the inclined portion 69 and the widened shape of the leg mounting bracket 39, the stress generated in the leg mounting bracket 39 with respect to the load acting on the leg mounting bracket 39 from the leg 37 is dispersed and further equalized. It becomes possible.

さらに、脚接合部６０において、脚部３７との溶接接合するために形成された円弧状のビード形状部７１は、脚接合部６０から傾斜部６９及び締結部である脚前フランジ部６５及び脚後フランジ部６７の開放端に至るまで連続して形成されている。
ビード形状部７１の円弧状のビード形状の幅Ｗ３についても、傾斜部６９の拡幅形状に合わせるように増大させてもよい。
脚接合部６０における溶接のための円弧状のビード形状部７１が、脚接合部６０から傾斜部６９及び締結部脚前フランジ部６５及び脚後フランジ部６７の先端側の開放端に至るまで連続して形成されるので、脚部取付けブラケット３９の剛性を向上でき強度を高めることができる。 Further, in the leg joint portion 60, the arc-shaped bead-shaped portion 71 formed for welding and joining to the leg portion 37 is composed of the leg joint portion 60 to the inclined portion 69, the leg front flange portion 65, which is a fastening portion, and the leg. It is continuously formed up to the open end of the rear flange portion 67.
The arc-shaped bead-shaped width W3 of the bead-shaped portion 71 may also be increased to match the widened shape of the inclined portion 69.
An arc-shaped bead-shaped portion 71 for welding in the leg joint portion 60 continues from the leg joint portion 60 to the open end on the tip side of the inclined portion 69, the fastening portion leg front flange portion 65, and the leg rear flange portion 67. Therefore, the rigidity of the leg mounting bracket 39 can be improved and the strength can be increased.

図６に示すように、本発明のリヤシートクロスメンバ３１の本体部３５を構成するパイプ部材は、標準的な体形の乗員の臀部の略前方に位置した高さに設けられており、前面衝突時等に、着座してシートベルトを装着した乗員は、慣性力によってシートクッション部１５に沈み込みながら下へ潜り込む姿勢になって腰ベルトが骨盤から外れてしまう、所謂サブマリン現象を、軽量コンパクトな構造によって抑制可能としている。   As shown in FIG. 6, the pipe member constituting the main body portion 35 of the rear seat cross member 31 of the present invention is provided at a height positioned substantially in front of the standard body occupant's buttocks, and at the time of a frontal collision The so-called submarine phenomenon, in which the occupant seated and seated with the seatbelt sinks into the seat cushion portion 15 due to inertial force and sinks downward, disengages from the pelvis, has a light and compact structure. Can be suppressed.

すなわち、パイプ部材からなる本体部３５と、曲げ部４３と、脚部３７と、さらに、それらを支持する中央ブラケット４１と、脚部取付けブラケット３９とから構成することで、軽量コンパクトな構造によって、サブマリン現象を抑制し、腰ベルトの適正な高速を維持可能としている。   That is, by comprising a main body portion 35 made of a pipe member, a bending portion 43, a leg portion 37, a central bracket 41 for supporting them, and a leg portion mounting bracket 39, a lightweight and compact structure, The submarine phenomenon is suppressed, and the proper high speed of the waist belt can be maintained.

また、リヤシートクロスメンバ３１の本体部３５はパイプ部材であり、角張っていないため、シートクッション部１５に着座した際に、すわり心地に違和感を与えることも少ないため、違和感を解消するために別部材を介在させる等の対策も不要となり、コスト低減効果をも有している。   Further, since the main body portion 35 of the rear seat cross member 31 is a pipe member and is not angular, when sitting on the seat cushion portion 15, there is little uncomfortable feeling in the sitting comfort. No measures such as intervening are required, and the cost is reduced.

本発明の少なくとも一実施形態によれば、リヤシートクッションの前方部分の内部に設けられるリヤシートクロスメンバを大型化及び重量増大化することなく、シートベルトを装着した乗員が、腰ベルトからすり抜けるサブマリン現象を抑制できるので、自動車のリヤシートクッションの支持に適している。   According to at least one embodiment of the present invention, a submarine phenomenon in which a passenger wearing a seat belt slips through a waist belt without increasing the size and weight of a rear seat cross member provided in the front portion of the rear seat cushion. Since it can be suppressed, it is suitable for supporting the rear seat cushion of an automobile.
