The seat cushion structure is characterized in that, from the opening rear edge of the groove toward the opening front edge of the groove, it includes an extendedly provided piece extendedly provided between the floor panel and the insert member and includes a seat member arranged between the insert member and the floor panel in the periphery of the opening front edge of the groove, and that the insert member is not in contact with the floor panel between the rear end of the seat member and the front end of the extendedly provided piece.

Description

本発明は、車両用シートクッション構造に関し、特にフロアパネル上に載置して固定されるバックシートの異音防止構造に関する。   The present invention relates to a vehicle seat cushion structure, and more particularly, to a back seat noise prevention structure that is placed and fixed on a floor panel.

従来、車両用シートには、車両前面側が衝突した際に、乗員が前斜め下方へ滑り込む、いわゆるサブマリン現象を防止するために、シートクッションの前半にシートクッション本体よりも硬質の発泡材によるすべり防止部材を配置した、車両用シートクッション構造が知られている。   Conventionally, in order to prevent the so-called submarine phenomenon that the passenger slips forward and obliquely downward when the front side of the vehicle collides with the vehicle seat, the front seat is prevented from slipping by a foam material harder than the seat cushion body. A vehicle seat cushion structure in which members are arranged is known.

図７を参照して、特許文献１によれば、車両用シートのシートクッション１０１の底面部１１２の前半に下方へ開口する横長の溝部１１３を形成し、溝部１１３に下方から、車両の前面衝突時等に着座した乗員の前すべりを防止するシートクッション１０１本体よりも硬質発泡材からなる前すべり防止部材１０２が嵌め込まれた車両用シートのシートクッション構造において、溝部１１３の開口縁部に、これから溝部１１３の中央側へ向けて突出する複数の受け部１１４を設け、これらにより溝部１１３へ嵌め込まれた前すべり防止部材１０２を受け止めて、その脱落を防止する発明が開示されている。前すべり防止部材１０２の底面部１２１と座面部１５１とは、重ね合わせて前すべり防止部材１０２を支えるように構成されている。   Referring to FIG. 7, according to Patent Document 1, a laterally long groove portion 113 that opens downward is formed in the first half of the bottom surface portion 112 of the seat cushion 101 of the vehicle seat. In the seat cushion structure of the vehicle seat in which the front slip prevention member 102 made of a hard foam material is fitted rather than the seat cushion 101 main body that prevents the front seat of the occupant seated at the time, etc. An invention is disclosed in which a plurality of receiving portions 114 projecting toward the center side of the groove portion 113 are provided, and the front slip prevention member 102 fitted into the groove portion 113 is received thereby to prevent the drop-out. The bottom surface portion 121 and the seating surface portion 151 of the front slip prevention member 102 are configured to support the front slip prevention member 102 in a superimposed manner.

また、特許文献２には、このような発泡ポリスチレンが裏面に配置されたシートパッドは、わずかな移動によってフロアパネルとの間でスティックスリップによる異音を発生するとして、これを解決する発明も開示されている。   Patent Document 2 also discloses an invention that solves such a problem that a seat pad having such a polystyrene foam disposed on the back surface generates abnormal noise due to stick-slip with a floor panel by slight movement. Has been.

例えば図８を参照して、特許文献２によれば、シートパッド２０１のサイドサポート部２０４の裏面に発泡成形体２２０が配置され、この発泡成形体２２０の底面が不織布等よりなるサポータ材２３０によって覆われており、発泡成形体２２０とシートフレーム等との摺動による異音の発生が防止される発明が開示されている。   For example, referring to FIG. 8, according to Patent Document 2, a foam molded body 220 is disposed on the back surface of the side support portion 204 of the seat pad 201, and the bottom surface of the foam molded body 220 is covered with a supporter material 230 made of a nonwoven fabric or the like. In other words, an invention is disclosed in which the generation of abnormal noise due to sliding between the foam molded body 220 and a seat frame or the like is prevented.

しかしながら、特許文献１に記載されたシートパッドでは、特許文献２が指摘するように、車両の移動時や、搭乗者の着座時等において、座面部１５１と発泡成形体を材料とする前すべり防止部材１０２とが擦れて、スティックスリップによる「キュッ、キュッ」という異音が発生する問題があった。   However, in the seat pad described in Patent Document 1, as pointed out by Patent Document 2, when the vehicle is moved or when a passenger is seated, the seat pad 151 and the foamed molded body are used to prevent the pre-slip. There was a problem that the member 102 was rubbed and an abnormal noise due to stick-slip was generated.

また、特許文献２に記載されたシートクッション構造では、車両の移動時や、搭乗者の着座時等における発泡成形体２２０とシートフレーム等との摺動による異音の発生を防止するために、発泡成形体２２０の底面全面をサポータ材２３０で覆っているので、コストおよび製造工程が増加する問題があった。   Further, in the seat cushion structure described in Patent Document 2, in order to prevent the generation of abnormal noise due to sliding between the foam molded body 220 and the seat frame when the vehicle is moved or when the passenger is seated, etc. Since the entire bottom surface of the foamed molded product 220 is covered with the supporter material 230, there is a problem that costs and manufacturing processes increase.

そこで、本発明は、インサート部材の全面を不織布等のサポート材で覆わなくても、フロアパネルとインサート部材とが擦れて異音が発生しないシートクッション構造を提供することを目的とする。   Therefore, an object of the present invention is to provide a seat cushion structure in which the floor panel and the insert member do not rub against each other even if the entire surface of the insert member is not covered with a support material such as a nonwoven fabric.

上記課題解決のため、本発明のシートクッション構造は、フロアパネル上にシート部材を挟んで載置され、シートクッションの底面部に下方へ開口するように形成された溝部と、前記溝部内に埋設されたインサート部材を有するシートクッション構造であって、前記溝部の開口後縁から前記溝部の開口前縁に向かって、前記フロアパネルと前記インサート部材の間に延設させた延設片と、前記溝部の開口前縁周辺で前記インサート部材と前記フロアパネルの間に配置されたシート部材とを有し、前記シート部材の後端と前記延設片の前端の間で、前記インサート部材が前記フロアパネルに接触していないことを特徴とする。   In order to solve the above problems, the seat cushion structure of the present invention is placed on a floor panel with a seat member interposed therebetween, and a groove portion formed to open downward on the bottom surface portion of the seat cushion, and embedded in the groove portion A seat cushion structure having an inserted member, the extending piece extending between the floor panel and the insert member from the opening rear edge of the groove portion toward the opening front edge of the groove portion, A sheet member disposed between the insert member and the floor panel around the opening front edge of the groove, and the insert member is disposed between the rear end of the sheet member and the front end of the extended piece. It is characterized by not touching the panel.

本発明によれば、インサート部材全面を不織布等のサポート材で覆わなくても、フロアパネルとインサート部材とが擦れて異音が発生せず、かつ前衝突時の乗員の前滑り防止およびチャイルドシートの前下方への移動量低下を実現できるシートクッションが、低コストに製造できる。   According to the present invention, even if the entire surface of the insert member is not covered with a support material such as a non-woven fabric, the floor panel and the insert member are not rubbed and no abnormal noise is generated. A seat cushion capable of realizing a reduction in the amount of forward and downward movement can be manufactured at a low cost.

（実施の形態１）
以下、図面を参照しながら、第１の実施形態について説明する。 (Embodiment 1)
Hereinafter, the first embodiment will be described with reference to the drawings.

以下の説明において、「上」「下」「側」「前」「後」の語は、車両の、「上方」「下方」「側方」「前方」「後方」にそれぞれ対応したものを表すことにする。   In the following description, the terms “upper”, “lower”, “side”, “front”, and “rear” represent those corresponding to “upper”, “lower”, “side”, “front”, and “rear”, respectively. I will decide.

図１には、本発明のシートクッションの概観の斜視図を示す。本発明のシートクッション構造を利用できるシートクッションは、シートクッション１、インサート部材２、シートバック１５を有する。   FIG. 1 shows a perspective view of the appearance of the seat cushion of the present invention. A seat cushion that can utilize the seat cushion structure of the present invention includes a seat cushion 1, an insert member 2, and a seat back 15.

図２には、シートクッション１を下方から見たときの斜視図を示す。シートクッション１の底面は、下方へ開口する溝部５を有する。溝部５はシートクッション１の下方から見ると略矩形形状をしており、後方の開口縁部６には延設片３が形成されている。溝部５には、後述するインサート部材２が埋設されている。延設片３は、シートクッション１の溝部５に埋設した状態でインサート部材２を押止している。後述するように、シートクッション１とインサート部材２とは、いわゆるインサート形成によって一体形成されるので、インサート部材２はシートクッション１と精度よく密着した状態で、埋設されている。   FIG. 2 shows a perspective view of the seat cushion 1 when viewed from below. The bottom surface of the seat cushion 1 has a groove portion 5 that opens downward. The groove portion 5 has a substantially rectangular shape when viewed from below the seat cushion 1, and an extended piece 3 is formed on the rear opening edge portion 6. An insert member 2 described later is embedded in the groove portion 5. The extending piece 3 holds the insert member 2 in a state of being embedded in the groove portion 5 of the seat cushion 1. As will be described later, since the seat cushion 1 and the insert member 2 are integrally formed by so-called insert formation, the insert member 2 is embedded in a state of being in close contact with the seat cushion 1 with high accuracy.

図３に、図１に示した本発明のシートクッション構造のＡ−Ａ断面を示す。本発明のシートクッション構造は、上述したシートクッション１、インサート部材２、延設片３、溝部５、シートバック１５に加えて、前方押止部材１２、後方押止部材１３、および枠体を備え、シート部材４を介して、フロアパネル１０の上に着設される。   FIG. 3 shows an AA cross section of the seat cushion structure of the present invention shown in FIG. The seat cushion structure of the present invention includes a front pressing member 12, a rear pressing member 13, and a frame in addition to the seat cushion 1, the insert member 2, the extending piece 3, the groove portion 5, and the seat back 15 described above. The sheet member 4 is attached on the floor panel 10.

シートクッション１は、座面の前方が後方より高く形成されており、前方から後方に向けて緩やかに降下し、再度後方で上昇する斜面形状をしている。シートクッション１には、保形のために略矩形形状の枠体が埋設されている（図示せず）。枠体は、座面に沿ってシートクッション１の後方まで延在している。枠体末端１４は、シートクッション１の外部で後方押止部材１３に着設されている。シートクッション１の、前方は前方押止部材１２により、後方は後方押止部材１３により、フロアパネル１０に着設されている。   The seat cushion 1 is formed such that the front of the seat surface is higher than the rear, and has a slope shape that gently descends from the front to the rear and rises again at the rear. A substantially rectangular frame is embedded in the seat cushion 1 for shape retention (not shown). The frame extends to the rear of the seat cushion 1 along the seating surface. The frame end 14 is attached to the rear pressing member 13 outside the seat cushion 1. The seat cushion 1 is attached to the floor panel 10 by a front pressing member 12 on the front side and a rear pressing member 13 on the rear side.

なお、シートクッション１は、ポリウレタンを材料としているが、ポリウレタンと同様の弾力性がある材料であれば、これに限定されない。   Although the seat cushion 1 is made of polyurethane, the seat cushion 1 is not limited to this as long as it has the same elasticity as polyurethane.

インサート部材２は、延設片３によってフロアパネル１０から離れた状態になるように溝部５に埋設された状態で押止されている。つまり、インサート部材２とフロアパネル１０とは、非接触状態になるように構成されている。   The insert member 2 is held in a state of being embedded in the groove portion 5 so as to be separated from the floor panel 10 by the extended piece 3. That is, the insert member 2 and the floor panel 10 are configured to be in a non-contact state.

図４には、図２のＢ−Ｂ断面を示す。シートクッション１の両側部では、シートクッション１部材から延設片３ｓが、インサート部材２の下方に回りこんで形成されているので、インサート部材２がフロアパネル１０に接触することはない。   FIG. 4 shows a BB cross section of FIG. On both sides of the seat cushion 1, the extending piece 3 s is formed so as to wrap around the lower part of the insert member 2 from the seat cushion 1 member, so that the insert member 2 does not contact the floor panel 10.

再び図３を参照して、フロアパネル１０とインサート部材２とは、約１０ｍｍ以上離れた状態になるように、インサート部材２が形成されていることが好適である。さらに、延設片３で押止されているインサート部材２の後端部分は、フロアパネル１０から、２０ｍｍ以上離れていることが好適であり、３０ｍｍ以上離れていることが最適である。この程度の距離で両部材を離隔しておけば、シートクッション１上に乗員が乗っても、インサート部材２がフロアパネル１０に接触することがないからである。   Referring to FIG. 3 again, it is preferable that the insert member 2 is formed so that the floor panel 10 and the insert member 2 are separated from each other by about 10 mm or more. Furthermore, it is preferable that the rear end portion of the insert member 2 held by the extending piece 3 is separated from the floor panel 10 by 20 mm or more, and optimally 30 mm or more. This is because if the two members are separated by such a distance, the insert member 2 will not contact the floor panel 10 even if an occupant gets on the seat cushion 1.

インサート部材２は、発泡ポリスチレン（以下、発泡ＰＳと言う）や発泡ポリプロピレン（以下、発泡ＰＰと言う）等のシートクッション１より硬い材料から構成されている。車両前面衝突時の乗員のサブマリン現象を回避し、またチャイルドシートの前下方の移動量を低減するためである。インサート部材２を構成する材料は、発泡ＰＳ及び発泡ＰＰと同様の弾力性がある材料であれば、これに限定されない。   The insert member 2 is made of a material harder than the seat cushion 1 such as expanded polystyrene (hereinafter referred to as expanded PS) or expanded polypropylene (hereinafter referred to as expanded PP). This is to avoid the occupant's submarine phenomenon at the time of a frontal collision of the vehicle and to reduce the amount of movement of the child seat in the front and lower direction. The material which comprises the insert member 2 will not be limited to this, if it is a material with the elasticity similar to foaming PS and foaming PP.

インサート部材２を埋設したシートクッション１は、いわゆるインサート成形によって製造されている。以下に、インサート成形により、インサート部材２を埋設したシートクッション１を製造する方法について簡単に説明する。   The seat cushion 1 in which the insert member 2 is embedded is manufactured by so-called insert molding. Below, the method to manufacture the seat cushion 1 which embedded the insert member 2 by insert molding is demonstrated easily.

まず、発泡ＰＳ等の材料を用いて、予めインサート部材２が製造される。次に、シートクッション１の金型にインサート部材２を組み込み、続いて、インサート部材２を組み込んだ金型にポリウレタンを注入する。次に、ポリウレタンが凝固した後、金型からインサート部材２が埋設したシートクッション１を取り出して、シートクッション１およびインサート部材２が一体となった成形品を得る。   First, the insert member 2 is manufactured in advance using a material such as foamed PS. Next, the insert member 2 is incorporated into the mold of the seat cushion 1, and then polyurethane is injected into the mold in which the insert member 2 is incorporated. Next, after the polyurethane is solidified, the seat cushion 1 in which the insert member 2 is embedded is taken out of the mold to obtain a molded product in which the seat cushion 1 and the insert member 2 are integrated.

なお、シートクッション１とインサート部材２とを別個に製造した後で、シートクッション１にインサート部材２を埋設するようにしてもよい。   Note that the insert member 2 may be embedded in the seat cushion 1 after the seat cushion 1 and the insert member 2 are manufactured separately.

シート部材４は、インサート部材２の前端とフロアパネル１０との間に介在されている。シート部材４により、発泡ＰＳ等を材料とするインサート部材２の前端と、フロアパネル１０とが、直接接触して、擦れることはないので、異音の発生を防止することができる。また、シート部材４には、不織布等を材料として用いることが好適である。フロアパネルとの間でスティックスリップ等の異音が発生しないからである。具体的には、アラミド繊維、ガラス繊維、セルロース繊維、ナイロン繊維、等を原料とした不織布を用いることができ、また、これらに限定されることはない。   The sheet member 4 is interposed between the front end of the insert member 2 and the floor panel 10. Since the sheet member 4 does not rub against the front end of the insert member 2 made of foamed PS or the like and the floor panel 10, it is possible to prevent the generation of abnormal noise. The sheet member 4 is preferably made of a nonwoven fabric or the like as a material. This is because noise such as stick-slip does not occur between the floor panel. Specifically, a nonwoven fabric made from aramid fiber, glass fiber, cellulose fiber, nylon fiber, or the like can be used, but is not limited thereto.

また、シート部材４を用いなくても、インサート部材２の前端位置に対応するフロアパネル１０の位置までフロアカーペットを引き込んで、インサート部材２とフロアパネル１０との間に、該フロアカーペットを介在させる構成にしても、上記と同様の効果を奏することができる。   Even without using the sheet member 4, the floor carpet is drawn to the position of the floor panel 10 corresponding to the front end position of the insert member 2, and the floor carpet is interposed between the insert member 2 and the floor panel 10. Even if it comprises, the effect similar to the above can be show | played.

シート部材４をフロアカーペットで代用すれば、シート部材４をシートクッション形成時に同時に形成する必要がなく、また、従来シートクッション１の後縁まで延設したフロアカーペットをシートクッション１の前縁まで配置すればよいので、材料コストを低く抑えることが出来る。   If the seat member 4 is replaced with a floor carpet, it is not necessary to form the seat member 4 at the same time when the seat cushion is formed, and a floor carpet extending to the rear edge of the conventional seat cushion 1 is arranged up to the front edge of the seat cushion 1 Therefore, the material cost can be kept low.

また、本実施形態によれば、荷重が最大限掛るインサート部材２の前端部が、シート部材４のみを介してフロアパネル１０に設置されている（図３参照）。つまり、インサート部材２の前端部とフロアパネル１０との間に、インサート部材２より柔らかいシートクッション１を介していないので、搭乗者の荷重によるシートクッション構造の変形量が少なくて済む。また、前衝突時の乗員の前滑り現象の回避や、チャイルドシートの前下方の移動量も低減できる。   Moreover, according to this embodiment, the front-end part of the insert member 2 to which load is applied to the maximum is installed in the floor panel 10 only through the sheet | seat member 4 (refer FIG. 3). That is, since the seat cushion 1 that is softer than the insert member 2 is not interposed between the front end portion of the insert member 2 and the floor panel 10, the amount of deformation of the seat cushion structure due to the passenger's load can be reduced. In addition, it is possible to avoid an occupant's front slip phenomenon at the time of a front collision and to reduce the amount of movement of the child seat in the front and lower direction.

また、インサート部材２がシートクッション１の開口部分で露出しているので、インサート部材２の全体をシートクッション１で覆うように一体成型した場合に比べて、シートクッション１の材料が少なくて済み、製造コストを削減することができる。   Moreover, since the insert member 2 is exposed at the opening portion of the seat cushion 1, the material of the seat cushion 1 can be reduced compared to a case where the insert member 2 is integrally molded so as to cover the entire insert member 2 with the seat cushion 1, Manufacturing costs can be reduced.

また、発泡ＰＳ等で構成されたシートクッション１の下面の大部分が露出しているので、インサート成型時のセットが容易で精度を高くすることができる。   Further, since most of the lower surface of the seat cushion 1 made of foamed PS or the like is exposed, it is easy to set at the time of insert molding and the accuracy can be increased.

また、フロアパネル１０とインサート部材２との間に間隔があるので、車載部材や配線等を設置したり、フロアパネル１０の形状に自由度を持たせることができる。   In addition, since there is a gap between the floor panel 10 and the insert member 2, a vehicle-mounted member, wiring, or the like can be installed, or the shape of the floor panel 10 can be given flexibility.

なお、延設片３は、開口縁部６の後部に加えて側部に形成しても同様の効果を奏する。また、延設片３は、開口縁部６に沿って、連続的または断続的に形成してもよい。また、シートクッション１は、主に後部座席に使用されるものであるが、後部座席のみに用途は限定されず、前部座席に使用してもよい。   The extended piece 3 has the same effect even if it is formed on the side portion in addition to the rear portion of the opening edge portion 6. Further, the extended piece 3 may be formed continuously or intermittently along the opening edge 6. Moreover, although the seat cushion 1 is mainly used for a rear seat, an application is not limited only to a rear seat, and may be used for a front seat.

（実施の形態２）
次に、第２の実施形態について説明する。本実施形態に係るシートクッション構造は、第１の実施形態に係るシートクッション構造と基本的に同様であり、シートクッション１の構成が相違する。このため、以下では、第１の実施形態に係るシートクッション構造と異なる部分のみ説明する。 (Embodiment 2)
Next, a second embodiment will be described. The seat cushion structure according to the present embodiment is basically the same as the seat cushion structure according to the first embodiment, and the configuration of the seat cushion 1 is different. For this reason, below, only a different part from the seat cushion structure which concerns on 1st Embodiment is demonstrated.

図５に、本実施形態のシートクッション構造を示す。延設片３は、溝部５の開口縁部６の、後部に加えて、前部にも形成されており、フロアパネル１０から離した状態で溝部５へ埋設したインサート部材２を押止している。   FIG. 5 shows the seat cushion structure of the present embodiment. The extending piece 3 is also formed in the front part in addition to the rear part of the opening edge part 6 of the groove part 5, and presses the insert member 2 embedded in the groove part 5 while being separated from the floor panel 10. Yes.

この様に構成することで、インサート部材２の前端および後端が、延設片３によってフロアパネル１０と接触しないようにシートクッション１に埋設されている。つまり、インサート部材２とフロアパネル１０とは完全に非接触状態にあるので、インサート部材２の前端とフロアパネル１０との間に介在させるシート部材４がなくても、フロアパネル１０とインサート部材２とが擦れて異音が発生することを防止できる。   By configuring in this way, the front end and the rear end of the insert member 2 are embedded in the seat cushion 1 so as not to contact the floor panel 10 by the extended piece 3. That is, since the insert member 2 and the floor panel 10 are in a completely non-contact state, the floor panel 10 and the insert member 2 can be provided without the sheet member 4 interposed between the front end of the insert member 2 and the floor panel 10. It is possible to prevent the generation of abnormal noise due to rubbing.

また、シート部材４を必要としないので、さらに製造コストを減らすことができ、また製造工程数を減らすことができる。   Further, since the sheet member 4 is not required, the manufacturing cost can be further reduced and the number of manufacturing steps can be reduced.

（実施の形態３）
次に、第３の実施形態について説明する。本実施形態に係るシートクッション構造は、第１の実施形態に係るシートクッション構造と基本的に同様であり、インサート部材２の形状が相違する。このため、以下では、第１の実施形態に係るシートクッション構造と異なる部分のみ説明する。 (Embodiment 3)
Next, a third embodiment will be described. The seat cushion structure according to the present embodiment is basically the same as the seat cushion structure according to the first embodiment, and the shape of the insert member 2 is different. For this reason, below, only a different part from the seat cushion structure which concerns on 1st Embodiment is demonstrated.

図６に本実施形態のシートクッション構造を示す。インサート部材２のフロアパネル１０に面する側２ａが、シートクッション１の座面方向に向けて湾入している。また、インサート部材２のフロアパネル１０に面する側２ａが、シートクッション１の座面方向に向けて凹陥しているように構成してもよい。   FIG. 6 shows the seat cushion structure of the present embodiment. The side 2 a facing the floor panel 10 of the insert member 2 enters the bay toward the seat surface direction of the seat cushion 1. Moreover, you may comprise so that the side 2a which faces the floor panel 10 of the insert member 2 may be dented toward the seat surface direction of the seat cushion 1. FIG.

このように構成することで、インサート部材２とフロアパネル１０とを、より確実に非接触状態とすることができ、フロアパネル１０とインサート部材２とが擦れて異音が発生することを防止できる。特に、大柄な搭乗者がシートクッション１に着座し、インサート部材２に上方から下方にかけて大きな力が加わった場合でも、インサート部材２とフロアパネル１０との間隔が広いので、インサート部材２がフロアパネル１０方向へある程度歪んでも確実に所定以上の間隔を空けて非接触状態を維持できるので、フロアパネル１０とインサート部材２とが擦れて異音が発生することを防止できる。   By comprising in this way, the insert member 2 and the floor panel 10 can be more reliably brought into a non-contact state, and the floor panel 10 and the insert member 2 can be prevented from being rubbed and generating abnormal noise. . In particular, even when a large passenger sits on the seat cushion 1 and a large force is applied to the insert member 2 from above to below, the distance between the insert member 2 and the floor panel 10 is wide. Even if it is distorted to some extent in 10 directions, it is possible to maintain a non-contact state with a predetermined interval or more, so that it is possible to prevent the floor panel 10 and the insert member 2 from rubbing and generating noise.

また、インサート部材２のフロアパネル１０に面する側が、シートクッション１の座面方向に向けて湾入しているので、湾入している体積分だけ発泡ＰＳ等の使用量が少なくなるので、コストを削減することができる。また、インサート部材２の湾曲面２ａは上方からの圧力を前後に分散するので、発泡ＰＳの使用量が少なくても、強度が高いという効果も奏することができる。   In addition, since the side facing the floor panel 10 of the insert member 2 is inserted into the seat cushion 1 in the seating surface direction, the amount of foamed PS and the like used is reduced by the volume of the entry into the bay. Cost can be reduced. Moreover, since the curved surface 2a of the insert member 2 disperses the pressure from above and behind, even if the amount of foamed PS used is small, the effect of high strength can be achieved.

以上のように、本発明のシートクッション構造は、シートクッション１より硬い発泡材で形成されたインサート部材２が着設されるフロアパネル１０と接触し、わずかな動きで生じるスティックスリップによる異音を防止するために、インサート部材２をシートクッション１に設けた延設片３と、シート部材４によってフロアパネル１０から浮かせて維持することとしたので、異音を回避できるばかりでなく、低コストを実現することができる。また、前衝突時の乗員の前滑り現象の回避や、チャイルドシートの前下方の移動量も低減できる。   As described above, the seat cushion structure according to the present invention is in contact with the floor panel 10 on which the insert member 2 formed of a foam material harder than the seat cushion 1 is attached, and generates abnormal noise due to stick slip generated by slight movement. In order to prevent this, the insert member 2 is kept floating from the floor panel 10 by the extended piece 3 provided on the seat cushion 1 and the seat member 4, so that not only abnormal noise can be avoided, but also low cost. Can be realized. In addition, it is possible to avoid an occupant's front slip phenomenon at the time of a front collision and to reduce the amount of movement of the child seat in the front and lower direction.

なお、本明細書で開示された実施形態は、例示的なものであって制限的なものではない。本発明の範囲は、特許請求の範囲およびそれと均等の範囲であることが意図される。   It should be noted that the embodiments disclosed herein are illustrative and not restrictive. The scope of the present invention is intended to be within the scope of the claims and their equivalents.
