特開２００１−３２８５６９号公報Japanese Unexamined Patent Publication No. 2001-328569

特許文献１の構造では、フロアパネルの上面に重ねられて固定されるシートバック支持ブラケットに、シート（シートバック）を固定するためのシート固定部とシートベルトアンカを固定するためのアンカ固定部とを設けているので、シート固定部とアンカ固定部とを別部材に設ける場合に比べて部品点数を削減することができる。 In the structure of Patent Document 1, a seat fixing portion for fixing the seat (seat back) and an anchor fixing portion for fixing the seat belt anchor are provided on the seat back support bracket which is overlapped and fixed on the upper surface of the floor panel. Therefore, the number of parts can be reduced as compared with the case where the seat fixing portion and the anchor fixing portion are provided on separate members.

しかし、シート固定部やアンカ固定部へ入力した荷重は、フロアパネルのうちシートバック支持ブラケットの周辺部位に集中して作用するため、フロアパネルが大きく変形する可能性がある。 However, since the load input to the seat fixing portion and the anchor fixing portion is concentrated on the peripheral portion of the seat back support bracket in the floor panel, the floor panel may be significantly deformed.

そこで本開示は、部品点数の増大を抑えつつ、シート固定部やアンカ固定部への荷重入力によるフロアパネルの変形を抑制することを目的とする。 Therefore, an object of the present disclosure is to suppress deformation of the floor panel due to load input to the seat fixing portion and the anchor fixing portion while suppressing an increase in the number of parts.

上記目的を達成すべく、本発明の第１の態様は、シート側に設けられるシート側取付部とシートベルトアンカ側に設けられるアンカ側取付部とを車室内にそれぞれ取付けるための車両のフロア構造であって、フロアパネルとフロアアンダフレームとレインフォースとを備える。フロアパネルは、シート側取付部が車室側から重なるシート被取付部と、アンカ側取付部が車室側から重なるアンカ被取付部とを有し、車室の床を形成する。フロアアンダフレームは、フロアパネルの裏面にフロアパネルの骨格として固定される。 In order to achieve the above object, the first aspect of the present invention is a vehicle floor structure for mounting a seat-side mounting portion provided on the seat side and an anchor-side mounting portion provided on the seatbelt anchor side in a vehicle interior. It is equipped with a floor panel, a floor underframe, and a reinforcement. The floor panel has a seat-mounted portion in which the seat-side mounting portion overlaps from the vehicle interior side and an anchor-mounted portion in which the anchor-side mounting portion overlaps from the vehicle interior side, and forms the floor of the vehicle interior. The floor under frame is fixed to the back surface of the floor panel as a skeleton of the floor panel.

レインフォースは、シート被取付部に反車室側から重なるシート固定部とアンカ被取付部に反車室側から重なるアンカ固定部とを有し、フロアパネルの裏面に固定される。シート側取付部とアンカ側取付部とは、シート固定部とアンカ固定部とに対してそれぞれ固定される。レインフォースは、フロアアンダフレームに結合される。 The reinforcement has a seat fixing portion that overlaps the seat mounting portion from the anti-vehicle compartment side and an anchor fixing portion that overlaps the anchor mounting portion from the anti-vehicle compartment side, and is fixed to the back surface of the floor panel. The seat side mounting portion and the anchor side mounting portion are fixed to the seat fixing portion and the anchor fixing portion, respectively. The reinforcement is combined with the floor underframe.

上記構成では、１つのレインフォースにシート固定部とアンカ固定部とを設けているので、シート固定部とアンカ固定部とを別部材に設ける場合に比べて部品点数を削減することができる。 In the above configuration, since the seat fixing portion and the anchor fixing portion are provided in one reinforcement, the number of parts can be reduced as compared with the case where the seat fixing portion and the anchor fixing portion are provided in separate members.

また、レインフォースをフロアパネルに固定するとともにフロアアンダフレームに結合しているので、車両衝突時等において、シートやシートベルトからレインフォースのシート固定部やアンカ固定部へ入力した荷重は、フロアパネルとフロアアンダフレームとに分散して作用する。このため、フロアパネルのうちレインフォースの周辺部位への荷重の集中を緩和することができ、シート固定部やアンカ固定部への荷重入力によるフロアパネルの変形を抑制することができる。 In addition, since the reinforcement is fixed to the floor panel and connected to the floor underframe, the load input from the seat or seat belt to the seat fixing part or anchor fixing part of the reinforcement is applied to the floor panel in the event of a vehicle collision or the like. And the floor underframe work in a distributed manner. Therefore, it is possible to relax the concentration of the load on the peripheral portion of the floor panel of the reinforcement, and it is possible to suppress the deformation of the floor panel due to the load input to the seat fixing portion and the anchor fixing portion.

本発明の第２の態様は、第１の態様のフロア構造であって、シート被取付部とアンカ被取付部とは、シート前後方向の位置が略等しくなるようにシート幅方向に離間して配置される。フロアアンダフレームは、シート被取付部及びアンカ被取付部のシート幅方向一側でシート前後方向に延びる。レインフォースは、シート固定部及びアンカ固定部からシート幅方向一側へ延びてフロアアンダフレームに結合される。 The second aspect of the present invention is the floor structure of the first aspect, in which the seat-mounted portion and the anchor-mounted portion are separated from each other in the seat width direction so that the positions in the front-rear direction of the seat are substantially equal to each other. Be placed. The floor underframe extends in the front-rear direction of the seat on one side of the seat attachment portion and the anchor attachment portion in the seat width direction. The reinforcement extends from the seat fixing portion and the anchor fixing portion to one side in the seat width direction and is connected to the floor under frame.

上記構成では、シート固定部とアンカ固定部とをシート前後方向の位置が略等しくなるように配置することができるので、レインフォースのシート前後方向の幅を短く設定することができ、レインフォースの小型化が可能となる。 In the above configuration, since the seat fixing portion and the anchor fixing portion can be arranged so that the positions in the seat front-rear direction are substantially equal, the width of the reinforcement in the seat front-rear direction can be set short, and the reinforcement can be set short. Miniaturization is possible.

本開示によれば、部品点数の増大を抑えつつ、シート固定部やアンカ固定部への荷重入力によるフロアパネルの変形を抑制することができる。 According to the present disclosure, it is possible to suppress the deformation of the floor panel due to the load input to the seat fixing portion and the anchor fixing portion while suppressing the increase in the number of parts.
