Description

前記課題は、本発明の車両用シートによれば、骨格となるフレームにクッション材を載置して表皮材で被覆されて構成され、前記クッション材と前記表皮材の間にシートヒータを備えた車両用シートであって、該クッション材は、シート幅方向の中央部分にあるクッション本体部と、該クッション本体部の左右外側にあるクッションサイド部と、を有し、該クッションサイド部には、凹部が形成され、該凹部は、シート幅方向において前記クッション材が前記フレームと当接している範囲内に配置され、かつ、シート幅方向において前記範囲の外側の端部分よりも内側に位置するように配置され、前記フレームは、シート幅方向の側方に配置される左右のサイドフレーム部を有し、前記凹部は、前記サイドフレーム部のうち、前記凹部側に最も突出している部分と重なる位置に配置されており、かつ、前記表皮材を吊り込むための吊り込み溝よりもシート幅方向において外側に位置するように配置されていること、により解決される。
上記のように、クッションサイド部には、凹部が形成されているため、シートの着座面に凹凸が発生することがなく、着座者に違和感を与えることがないシートヒータ付き車両用シートを実現できる。
特に、クッションサイド部においては、一般に表皮材の裏面に対して薄いワディング材が取り付けられるか、そもそもワディング材が取り付けられていないことが多く、シートヒータ設置による着座感の影響が大きくなるため、本発明の効果が際立つようになる。
また、上記のように、凹部は、シート幅方向においてクッション材がフレームと当接している範囲内に配置され、かつ、シート幅方向において前記範囲の外側の端部分よりも内側に位置するように配置されているため、凹部が形成された部分がフレームに好適に支持され、当該部分における過度な弾性変形が抑制される。その結果、シートヒータの変形が抑制され、ヒータ機能を好適に維持することができる。 The object is to provide a vehicle seat according to the present invention, in which a cushion material is placed on a frame serving as a skeleton and covered with a skin material, and a seat heater is provided between the cushion material and the skin material. In a vehicle seat, the cushion material has a cushion body portion at a central portion in a seat width direction and cushion side portions on left and right outer sides of the cushion body portion, and the cushion side portion includes A concave portion is formed, and the concave portion is arranged within a range where the cushion material is in contact with the frame in the seat width direction, and is positioned inside an outer end portion of the range in the seat width direction. disposed, the frame has a side frame portion of the left and right are arranged on the side of the seat width direction, the recess, of the side frame portion, the top into the recess side Is disposed at a position overlapping the protruding to have portions, and that are disposed so as to be positioned on the outside in the seat width direction than the upholstered groove for Komu hanging the skin material, is solved by.
As described above, since the concave portion is formed in the cushion side portion, no irregularities are generated on the seating surface of the seat, and a vehicle seat with a seat heater that does not give a occupant an uncomfortable feeling can be realized. .
In particular, in the cushion side portion, a thin wadding material is generally attached to the back surface of the skin material, or the wadding material is often not attached in the first place, and the influence of the seating feeling due to the installation of the seat heater becomes large, so this type of seating material is used. The effect of the invention becomes prominent.
Further, as described above, the concave portion is arranged within a range where the cushioning material is in contact with the frame in the seat width direction, and is positioned inside the outer end portion of the range in the seat width direction. Due to the arrangement, the portion where the concave portion is formed is suitably supported by the frame, and excessive elastic deformation in the portion is suppressed. As a result, deformation of the seat heater is suppressed, and the heater function can be suitably maintained.

このとき、前記吊り込み溝は、前記クッションサイド部のうち、前記サイドフレーム部側とは反対側に最も突出している部分よりもシート幅方向において内側に配置されていると良い。 At this time, it is preferable that the suspension groove is disposed inward in the seat width direction of a portion of the cushion side portion most protruding on a side opposite to the side frame portion side .

このとき、前記クッションサイド部は、シート幅方向の外側に向かうに従って前記サイドフレーム部側とは反対側に突出するように形成され、前記吊り込み溝は、前記クッションサイド部のうち、前記サイドフレーム部側とは反対側に最も突出していない部分に近い位置に配置され、かつ、該最も突出していない部分よりもシート幅方向において内側に配置されていると良い。 At this time, the cushion side portion is formed so as to protrude to the side opposite to the side frame portion side toward the outside in the seat width direction, and the suspension groove is formed of the side frame of the cushion side portion. It is preferable to be arranged at a position close to the part that does not protrude most to the side opposite to the part side, and to be arranged more inward in the sheet width direction than the part that does not protrude most .

このとき、前記吊り込み溝は、前記サイドフレーム部のうち、前記凹部側に最も突出している部分よりも前記クッション材の裏面に向かって深く形成されていると良い。
また、前記凹部のシート幅方向における内側端部は、前記サイドフレーム部のうち、シート幅方向の外側に向かうに従って前記凹部側に突出していく部分と重なる位置に配置されており、前記凹部は、前記サイドフレーム部のうち、前記凹部側に最も突出している部分をシート幅方向において跨るように配置されていると良い。 At this time, it is preferable that the suspension groove is formed deeper toward the back surface of the cushion material than a portion of the side frame portion most protruding toward the recess .
Further, an inner end in the sheet width direction of the concave portion is disposed at a position overlapping with a portion of the side frame portion that protrudes toward the concave portion toward the outside in the sheet width direction, and the concave portion is It is preferable that the side frame portion is disposed so as to straddle a portion of the side frame portion most protruding toward the concave portion in the sheet width direction .

このとき、前記凹部は、前記シートヒータを収納させるための収納凹部であって、前記シートヒータは、シート状のシート基材と、該シート基材に取り付けられるヒータ線と、を備えていると良い。
また、前記収納凹部は、シート幅方向において両端部分から中央部分に向かうに従って深くなるように形成され、前記ヒータ線が、前記収納凹部において前記両端部分よりも前記中央部分側に配置されていると良い。
上記構成により、シートヒータにおいて重要なヒータ線の変形が一層抑制される。 At this time, the recess is a storage recess for storing the sheet heater, and the sheet heater includes a sheet-shaped sheet base and a heater wire attached to the sheet base. good.
Further, the storage recess is formed so as to be deeper from both end portions toward the central portion in the sheet width direction, and the heater wire is disposed closer to the central portion than the both end portions in the storage recess. good.
With the above configuration, the deformation of the important heater wire in the seat heater is further suppressed.

このとき、シートクッションとシートバックが連結される連結部分を備え、前記収納凹部は、前記クッションサイド部のシート幅方向とは直交する延出方向に沿って延びるように形成され、かつ、前記延出方向において前記連結部分から離れるに従って幅広となるように形成され、かつ、前記延出方向において前記クッションサイド部の略中央部分から前記連結部分側とは反対側に向かうに従って幅狭となるように形成されていると良い。
一般にシートクッションのサイドボルスター部分については、そのシート前方部分及び中央部分が、着座者の臀部が支持される部分であって着座荷重が加わる部分である。
そのため、当該シート前方部分及び中央部分が、シートヒータによって好適に暖めたい部分であって、かつ、シートヒータの変形を抑制し、着座感の影響を抑えたい部分となる。
そこで、上記収納凹部の構成とすれば、シートヒータの好適な形状、配置を実現し、かつ、シートヒータの変形を抑制することができる。また着座感への影響を抑えられる。 At this time, the seat cushion and the seat back are provided with a connecting portion to be connected, and the storage recess is formed so as to extend along an extending direction orthogonal to a seat width direction of the cushion side portion, and In the extension direction, it is formed so as to become wider as being away from the connection portion, and in the extension direction, it becomes narrower as it goes from the substantially central portion of the cushion side portion to the opposite side to the connection portion side. It is good to be formed .
In general, as for the side bolster portion of the seat cushion, a front portion and a center portion of the seat are portions where a seated person's buttocks are supported and a seating load is applied.
Therefore, the front portion and the center portion of the seat are portions that are to be suitably warmed by the seat heater and are portions that want to suppress the deformation of the seat heater and suppress the influence of the seating sensation.
Therefore, with the configuration of the storage recess, a suitable shape and arrangement of the seat heater can be realized, and deformation of the seat heater can be suppressed. In addition, the influence on the feeling of sitting can be suppressed.

このとき、乗員の頭を後方から支持するヘッドレストをさらに備えていると良い。 At this time, it is preferable to further include a headrest for supporting the occupant's head from behind .
