特開２０１２−５１４９４号公報Japanese Unexamined Patent Publication No. 2012-51494

特許文献１に記載されるような車両用シートでは、シートフレームが車両の前後方向にスライドした際に、車体側におけるワイヤーハーネスの取付座とシートフレームとの間にワイヤーハーネスが挟み込まれる懸念がある。具体的に、ワイヤーハーネスが屈曲した状態で配策される構造である場合、シートフレーム側におけるワイヤーハーネスの接続部には剛性が求められるため、その接続部の厚さを大きくする場合がある。そうすると、接続部が取付座と上下方向に重なった状態における接続部と取付座との隙間が小さくなるため、その隙間にワイヤーハーネスが挟み込まれるリスクが高まる。 In a vehicle seat as described in Patent Document 1, when the seat frame slides in the front-rear direction of the vehicle, there is a concern that the wire harness may be sandwiched between the mounting seat of the wire harness on the vehicle body side and the seat frame. .. Specifically, in the case of a structure in which the wire harness is arranged in a bent state, the connection portion of the wire harness on the seat frame side is required to have rigidity, so that the thickness of the connection portion may be increased. Then, since the gap between the connection portion and the mounting seat when the connecting portion overlaps the mounting seat in the vertical direction becomes small, the risk of the wire harness being caught in the gap increases.

本発明の目的は、シートフレームが前後方向に移動する際における当該シートフレームと取付座との間へのワイヤーハーネスの挟み込みを抑制可能な車両用シートを提供することである。 An object of the present invention is to provide a vehicle seat capable of suppressing pinching of a wire harness between the seat frame and the mounting seat when the seat frame moves in the front-rear direction.

この発明に従った車両用シートは、車体の前後方向に沿って前記車体に対して相対変位可能となるように前記車体に取り付けられるシートフレームであって、前記車体に設けられた取付座と上下方向に重なる重なり位置と、前記車体の前後方向に前記取付座から離間した離間位置と、の間で移動する移動部を有する前記シートフレームと、前記シートフレームに搭載される電装品と前記車体に設けられた接続部とを接続するワイヤーハーネスと、前記ワイヤーハーネスの一部を前記取付座に固定する車体側取付部材と、前記ワイヤーハーネスの他の一部を前記移動部に固定するフレーム側取付部材と、を備える。前記フレーム側取付部材は、前記移動部に接続される接続部であって、前記移動部が前記重なり位置に位置するときにおける前記接続部と前記取付座との隙間が前記ワイヤーハーネスの直径よりも小さくなる位置で、かつ、前記移動部が前記離間位置に位置するときに前記ワイヤーハーネスと上下方向に重なる位置に配置された前記接続部と、前記ワイヤーハーネスを受ける受け部であって、前記移動部が前記重なり位置に位置するときにおける前記受け部と前記取付座との隙間が前記ワイヤーハーネスの直径よりも大きくなる位置に配置された前記受け部と、前記移動部が前記離間位置から前記重なり位置に向けて移動する過程において、前記接続部が前記取付座と上下方向に重なる前に前記ワイヤーハーネスを前記接続部から前記受け部に向けて案内する案内部と、を有する。 A vehicle seat according to the present invention is a seat frame attached to the vehicle body so as to be relatively displaceable with respect to the vehicle body along the front-rear direction of the vehicle body, and is vertically and vertically connected to a mounting seat provided on the vehicle body. The seat frame having a moving portion that moves between an overlapping position that overlaps in the direction and a separated position that is separated from the mounting seat in the front-rear direction of the vehicle body, and the electrical components mounted on the seat frame and the vehicle body. A wire harness for connecting the provided connection portion, a vehicle body side mounting member for fixing a part of the wire harness to the mounting seat, and a frame side mounting for fixing the other part of the wire harness to the moving portion. It is provided with a member. The frame-side mounting member is a connecting portion connected to the moving portion, and the gap between the connecting portion and the mounting seat when the moving portion is located at the overlapping position is larger than the diameter of the wire harness. The connecting portion arranged at a position where the moving portion becomes smaller and at a position where the moving portion overlaps the wire harness in the vertical direction when the moving portion is located at the separated position, and a receiving portion that receives the wire harness. The receiving portion arranged at a position where the gap between the receiving portion and the mounting seat when the portions are located at the overlapping position is larger than the diameter of the wire harness, and the moving portion overlap from the separated position. In the process of moving toward the position, it has a guide portion that guides the wire harness from the connection portion toward the receiving portion before the connection portion overlaps the mounting seat in the vertical direction.

本車両用シートでは、シートフレームの移動部が離間位置から重なり位置に向けて移動する際、フレーム側取付部材の案内部は、接続部が取付座と上下方向に重なる前にワイヤーハーネスを接続部から受け部に向けて案内するため、移動部が重なり位置に位置する状態において、接続部と取付座との間にワイヤーハーネスが挟み込まれることが抑制される。 In the vehicle seat, when the moving part of the seat frame moves from the separated position to the overlapping position, the guide part of the frame side mounting member connects the wire harness before the connecting part overlaps the mounting seat in the vertical direction. Since the guide is directed toward the receiving portion, it is possible to prevent the wire harness from being pinched between the connecting portion and the mounting seat when the moving portions are located at overlapping positions.

また、前記ワイヤーハーネスは、前記車体側取付部材に固定された第１被固定部と、前記フレーム側取付部材に固定された第２被固定部と、前記第１被固定部と前記第２被固定部との間に位置する中間部と、を有し、前記中間部は、前記第１被固定部の端部に接続された第１取付部と、前記車体の幅方向において前記第１取付部より外側において前記第２被固定部の端部に接続された第２取付部と、前記第１取付部と前記第２取付部とを連結しており、前記車体の幅方向の内向きに凸となる湾曲する形状を有する連結部と、を有していてもよい。この場合において、前記接続部、前記案内部及び前記受け部は、前記車体の幅方向における外側に向かってこの順に並ぶように設けられていることが好ましい。 Further, the wire harness includes a first fixed portion fixed to the vehicle body side mounting member, a second fixed portion fixed to the frame side mounting member, the first fixed portion and the second covered portion. It has an intermediate portion located between the fixed portion, and the intermediate portion has a first mounting portion connected to an end portion of the first fixed portion and the first mounting portion in the width direction of the vehicle body. The second mounting portion connected to the end portion of the second fixed portion outside the portion, and the first mounting portion and the second mounting portion are connected to each other inward in the width direction of the vehicle body. It may have a connecting portion having a convex and curved shape. In this case, it is preferable that the connecting portion, the guiding portion, and the receiving portion are provided so as to be arranged in this order toward the outside in the width direction of the vehicle body.

具体的に、前記第１取付部は、前記第１被固定部の端部から前記車体の幅方向における内側に向かって伸びるように配策されており、前記第２取付部は、前記第２被固定部の端部から後方に向かって伸びるように配策されていることが好ましい。 Specifically, the first mounting portion is arranged so as to extend inward in the width direction of the vehicle body from the end portion of the first fixed portion, and the second mounting portion is the second mounting portion. It is preferable that the arrangement is such that it extends rearward from the end of the fixed portion.

また、前記接続部の厚さは、前記受け部の厚さよりも大きいことが好ましい。 Further, the thickness of the connecting portion is preferably larger than the thickness of the receiving portion.

また、前記接続部と前記案内部との境界部は、前記受け部から前記接続部に向かう向きに凸となるように湾曲する形状を有していることが好ましい。 Further, it is preferable that the boundary portion between the connecting portion and the guiding portion has a shape curved so as to be convex in the direction from the receiving portion toward the connecting portion.

このようにすれば、ワイヤーハーネスが受け部と接続部との間を移動する際における当該ワイヤーハーネスの破損が抑制される。 In this way, damage to the wire harness when the wire harness moves between the receiving portion and the connecting portion is suppressed.

以上に説明したように、この発明によれば、シートフレームが前後方向に移動する際における当該シートフレームと取付座との間へのワイヤーハーネスの挟み込みを抑制可能な車両用シートを提供することができる。 As described above, according to the present invention, it is possible to provide a vehicle seat capable of suppressing pinching of a wire harness between the seat frame and the mounting seat when the seat frame moves in the front-rear direction. it can.
