　本発明は、シートクッションの上下移動によるシートクッションの側壁部の外観品質の低下を防止できる車両用座席を提供する。 The present invention provides a vehicle seat that can prevent deterioration in the appearance quality of the side wall portion of the seat cushion due to the vertical movement of the seat cushion.
　本発明の第１の態様は、座席のベース部に対して上下方向へ移動可能とされたシートクッションと、前記ベース部に固定され、前記シートクッションのシート幅方向外側下部を覆う外観部品と、前記シートクッションの外周部に設けられ、側壁部の一部が前記シートクッションの上下動により、前記外観部品と干渉する表皮材と、前記表皮材に覆われると共に、前記表皮材の側壁部における前記シートクッションの上下動により前記外観部品と干渉する部位に対応する部位にシート幅方向内側へ凹んだ凹部が形成されているパッド材と、を有する車両用座席を提供する。 According to a first aspect of the present invention, a seat cushion that is movable in the vertical direction with respect to a base portion of a seat, an external component that is fixed to the base portion and covers an outer lower portion of the seat cushion in the seat width direction, Provided on the outer periphery of the seat cushion, a part of the side wall portion is covered with the skin material that interferes with the external parts by the vertical movement of the seat cushion, and the skin material is covered with the skin material, and the side wall portion of the skin material is There is provided a vehicle seat having a pad material in which a recess that is recessed inward in the seat width direction is formed at a portion corresponding to a portion that interferes with the appearance component due to vertical movement of a seat cushion.
　上記の態様では、車両用座席のシートクッションが、座席のベース部に対して上下方向へ移動すると、ベース部に固定されシートクッションのシート幅方向外側下部を覆う外観部品と、シートクッションの外周部に設けられた表皮材における側壁部の一部が、シートクッションの上下動により外観部品と干渉する。この際、表皮材によって覆われたパッド材には、表皮材の側壁部におけるシートクッションの上下動により外観部品と干渉する部位と対応する部位に、シート幅方向内側へ凹んだ凹部が形成されている。このため、外観部品との干渉により、表皮材は弾性変形により撓むが、表皮材が外観部品とパッド材との間に挟まれて圧痕が発生することはない。この結果、シートクッションの上昇時に、シートの側壁部に、外観部品との干渉による圧痕が露出することはない。この結果、シートクッションの上下移動によりシートクッションの側壁部の外観品質が低下するのを防止できる。 In the above aspect, when the seat cushion of the vehicle seat moves in the up-down direction with respect to the base portion of the seat, the external parts that are fixed to the base portion and cover the outer lower portion in the seat width direction of the seat cushion, and the outer peripheral portion of the seat cushion A part of the side wall portion of the skin material provided on the door interferes with the external parts by the vertical movement of the seat cushion. At this time, the pad material covered with the skin material is formed with a recess recessed inward in the seat width direction at a site corresponding to the site that interferes with the external parts due to the vertical movement of the seat cushion in the side wall of the skin material. Yes. For this reason, the skin material bends due to elastic deformation due to interference with the external part, but the skin material is not sandwiched between the external part and the pad material so that no impression is generated. As a result, when the seat cushion is raised, the indentation due to the interference with the appearance part is not exposed on the side wall portion of the seat. As a result, it is possible to prevent the appearance quality of the side wall portion of the seat cushion from being deteriorated due to the vertical movement of the seat cushion.
　本発明の第２の態様は、本発明の第１の態様において、前記パッド材における前記凹部の下方側部位が、前記凹部の上方側部位に比べてシート幅方向外側へ大きく突出していてもよい。 According to a second aspect of the present invention, in the first aspect of the present invention, the lower portion of the recess in the pad material may protrude more outward in the sheet width direction than the upper portion of the recess. .
　上記の態様では、シートクッションが上昇した際に、表皮材の撓みにより、パッド材における凹部の下方側部位がシート幅方向内側へ引っ張られ、経時変形により多少潰れることがある。この際、パッド材における凹部の下方側部位が、凹部の上方側部位に比べてシート幅方向外側へ大きく突出している。このため、凹部の下方側部位が多少潰れても、シートクッションが最上位置に移動した際に、凹部の下方側部位の潰れによる表皮材と外観部品との間の隙間が発生し難い。この結果、シートクッションの上下移動によりシートクッションの側壁部の外観品質が低下するのを防止できる。 In the above aspect, when the seat cushion is raised, the lower side portion of the recess in the pad material is pulled inward in the seat width direction due to the bending of the skin material, and may be slightly crushed due to temporal deformation. At this time, the lower portion of the recess in the pad material protrudes more outward in the sheet width direction than the upper portion of the recess. For this reason, even if the lower side portion of the concave portion is somewhat crushed, when the seat cushion moves to the uppermost position, a gap between the skin material and the appearance part due to the crushed lower side portion of the concave portion hardly occurs. As a result, it is possible to prevent the appearance quality of the side wall portion of the seat cushion from being deteriorated due to the vertical movement of the seat cushion.
　本発明の第１の態様は、上記構成としたので、シートクッションの上下移動によるシートクッションの側壁部の外観品質の低下を防止できる。 Since the first aspect of the present invention has the above-described configuration, it is possible to prevent deterioration in the appearance quality of the side wall portion of the seat cushion due to the vertical movement of the seat cushion.
　本発明の第２の態様は、上記構成としたので、シートクッションの上下移動によるシートクッションの側壁部の外観品質の低下を防止できる。 Since the second aspect of the present invention has the above-described configuration, it is possible to prevent deterioration in the appearance quality of the side wall portion of the seat cushion due to the vertical movement of the seat cushion.

　図１に示されるように、シートクッション１４は、パッド材としてのウレタンパッド２０（シートクッションパッド）を備えており、ウレタンパッド２０は、シートクッション１４の骨格部材である図示しないシートクッションフレームに支持されている。また、ウレタンパッド２０は、シートクッション２０の外周部に設けられた表皮材２２によって覆われており、表皮材２２は複数枚のピースが縫合糸２３によって縫合されている。即ち、複数枚のピースで構成された表皮材２２の内側部にウレタンパッド２０が設けられている。 As shown in FIG. 1, the seat cushion 14 includes a urethane pad 20 (seat cushion pad) as a pad material, and the urethane pad 20 is supported by a seat cushion frame (not shown) that is a skeleton member of the seat cushion 14. Has been. The urethane pad 20 is covered with a skin material 22 provided on the outer peripheral portion of the seat cushion 20, and a plurality of pieces of the skin material 22 are stitched together with a suture thread 23. That is, the urethane pad 20 is provided on the inner side of the skin material 22 composed of a plurality of pieces.
　なお、ウレタンパッド２０においてサイドサポート部１４Ｂを構成する部分がパッドサイド部２０Ａとなっており、表皮材２２においてサイドサポート部１４Ｂを構成する部分が表皮サイド部２２Ａとなっている。また、シートクッション１４の側壁部１４Ｃを構成するウレタンパッド２０の側壁部を覆う表皮材２２の部分が表皮材２２の側壁部（マチ部）２６となっている。 In addition, the part which comprises the side support part 14B in the urethane pad 20 is the pad side part 20A, and the part which comprises the side support part 14B in the skin material 22 is the skin side part 22A. Further, a portion of the skin material 22 that covers the side wall portion of the urethane pad 20 constituting the side wall portion 14 </ b> C of the seat cushion 14 is a side wall portion (gusset portion) 26 of the skin material 22.
　シートクッション１４の側壁部１４Ｃのシート幅方向外側には、外観部品としての樹脂製のカバー２４（外観部品）が設けられている。このカバー２４は、図５に示すようにアッパーレール１０Ｂに固定されている。従って、シート本体１２は、カバー２４に対して、上方（図５の矢印Ａ方向）と下方（図５の矢印Ｂ方向）とへ移動可能となっている。 A resin cover 24 (appearance part) is provided as an appearance part on the outer side in the seat width direction of the side wall part 14C of the seat cushion 14. The cover 24 is fixed to the upper rail 10B as shown in FIG. Therefore, the seat body 12 is movable upward (in the direction of arrow A in FIG. 5) and downward (in the direction of arrow B in FIG. 5) with respect to the cover 24.
　図１に示すように、カバー２４は、表皮材２２の側壁部２６における下部２６Ａのシート幅方向外側に設けられている。また、カバー２４の上端部には、シート幅方向外側からシート幅方向内側に向かって上壁部２４Ａが形成されている。そして、上壁部２４Ａの先端（シート幅方向内側端）２４Ｂが表皮材２２の側壁部２６にシート幅方向外側から当たっている。 As shown in FIG. 1, the cover 24 is provided on the outer side in the sheet width direction of the lower portion 26 </ b> A in the side wall portion 26 of the skin material 22. An upper wall portion 24A is formed at the upper end of the cover 24 from the outer side in the sheet width direction toward the inner side in the sheet width direction. And the front-end | tip (sheet width direction inner side end) 24B of upper wall part 24A has contacted the side wall part 26 of the skin material 22 from the sheet width direction outer side.
　本実施形態の表皮材２２は、一例としてファブリック（布地）、皮革又は合成皮革等の一層構造となっている。なお、図示しないが、表皮材２２は、表材としての織物２８、パッド材としてのスポンジウレタン３０、裏材としての薄い布地３２からなる３層構造や、表材としての織物２８とパッド材としてのスポンジウレタン３０とから成る二層構造等の他の構造としてもよい。 The skin material 22 of the present embodiment has a single layer structure such as a fabric, a leather or a synthetic leather as an example. Although not shown, the skin material 22 is a three-layer structure comprising a fabric 28 as a surface material, sponge urethane 30 as a pad material, and a thin fabric 32 as a backing material, or a fabric 28 and a pad material as a surface material. It is good also as other structures, such as the two-layer structure which consists of sponge urethane 30 of this.
　表皮材２２の側壁部２６はシートクッション１４が上下動する際に、上壁部２４Ａの先端２４Ｂと干渉するようになっている。一方、ウレタンパッド２０の側壁部２５における、表皮材２２の側壁部２６と、カバー２４の上壁部２４Ａの先端２４Ｂとが干渉する部位には凹部４０が形成されている。 The side wall portion 26 of the skin material 22 interferes with the front end 24B of the upper wall portion 24A when the seat cushion 14 moves up and down. On the other hand, in the side wall portion 25 of the urethane pad 20, a recess 40 is formed at a portion where the side wall portion 26 of the skin material 22 interferes with the tip 24 </ b> B of the upper wall portion 24 </ b> A of the cover 24.
　図２に示すように、シート本体１２のシートクッション１４が最も低い位置まで下降した状態では、凹部４０の上壁部４０Ａがカバー２４の上壁部２４Ａの上方近傍の位置となっている。なお、上壁部４０Ａはシート幅方向外側上方からシート幅方向内側下方へ向かって傾斜しており、上壁部４０Ａの下方側端部近傍に、カバー２４の上壁部２４Ａの先端２４Ｂが対向するようになっている。 As shown in FIG. 2, when the seat cushion 14 of the seat body 12 is lowered to the lowest position, the upper wall portion 40A of the recess 40 is located in the vicinity of the upper portion of the upper wall portion 24A of the cover 24. The upper wall portion 40A is inclined from the upper outer side in the seat width direction toward the lower inner side in the seat width direction, and the front end 24B of the upper wall portion 24A of the cover 24 is opposed to the lower side end portion of the upper wall portion 40A. It is supposed to be.
　図３に示すように、シート本体１２のシートクッション１４が最も高い位置まで上昇した状態では、凹部４０の下壁部４０Ｂが、カバー２４の上壁部２４Ａの下方近傍の位置となっている。なお、下壁部４０Ｂはシート幅方向に沿った略平面となっており、カバー２４の上壁部２４Ａと略平行になっている。 As shown in FIG. 3, in a state where the seat cushion 14 of the seat body 12 is raised to the highest position, the lower wall portion 40B of the recessed portion 40 is located near the lower portion of the upper wall portion 24A of the cover 24. The lower wall portion 40B is a substantially flat surface along the sheet width direction, and is substantially parallel to the upper wall portion 24A of the cover 24.
　図１に示すように、凹部４０はカバー２４の上壁部２４Ａに対向してシートクッション１４の前後方向に沿って延設されており、凹部４０の周囲４２は、凹部４０に対してシート幅方向外側に突出している。 As shown in FIG. 1, the recess 40 extends in the front-rear direction of the seat cushion 14 so as to face the upper wall portion 24 </ b> A of the cover 24, and the periphery 42 of the recess 40 has a seat width with respect to the recess 40. Projects outward in the direction.
　従って、ウレタンパッド２０の側壁部２５に凹部４０を形成したことで、シートクッション１４が上下動する際に、カバー２４の上壁部２４Ａの先端２４Ｂが、表皮材２２の側壁部２６を挟んでウレタンパッド２０の側壁部２５に干渉しないようになっている。このため、カバー２４の上壁部２４Ａの先端２４Ｂとの干渉により、表皮材２２の側壁部２６は弾性変形によりシート幅方向内側へ撓むが、表皮材２２の側壁部２６が、カバー２４の上壁部２４Ａの先端２４Ｂとウレタンパッド２０の側壁部２５との間に挟まれて圧痕が発生しないようになっている。 Therefore, since the recess 40 is formed in the side wall 25 of the urethane pad 20, when the seat cushion 14 moves up and down, the tip 24 B of the upper wall 24 A of the cover 24 sandwiches the side wall 26 of the skin material 22. It does not interfere with the side wall 25 of the urethane pad 20. For this reason, due to the interference with the tip 24B of the upper wall portion 24A of the cover 24, the side wall portion 26 of the skin material 22 bends inward in the sheet width direction due to elastic deformation, but the side wall portion 26 of the skin material 22 It is sandwiched between the tip 24B of the upper wall portion 24A and the side wall portion 25 of the urethane pad 20 so that no indentation is generated.
　また、ウレタンパッド２０の側壁部２５における凹部４０の下方側周囲４２Ａが、凹部４０の上方側周囲４２Ｂに比べてシート幅方向外側へ大きく突出しており、凹部４０のシートと幅方向内側となる底部４０Ｃからの下方側周囲４２Ａの肉厚Ｍ１が、上方側周囲４２Ｂの肉厚Ｍ２より大きくなっている（Ｍ１＞Ｍ２）。 In addition, the lower periphery 42A of the recess 40 in the side wall 25 of the urethane pad 20 protrudes more outward in the sheet width direction than the upper periphery 42B of the recess 40, and the bottom of the recess 40 that is on the inner side in the width direction. The thickness M1 of the lower periphery 42A from 40C is larger than the thickness M2 of the upper periphery 42B (M1> M2).
　従って、シートクッション１４が上昇した状態で、表皮材２２の側壁部２６の撓みにより、ウレタンパッド２０の側壁部２５における凹部４０の下方側周囲４２Ａがシート幅方向内側へ引っ張られ、凹部４０の下方側周囲４２Ａが多少潰れても、図３に示すように、（シートクッション１４が最上位置に移動した際に、）凹部４０の下方側周囲４２Ａの潰れによる表皮材２２の側壁部２６と、カバー２４の上壁部２４Ａの先端２４Ｂとの間の隙間が発生し難いようになっている。 Therefore, in the state where the seat cushion 14 is raised, the lower side periphery 42A of the recess 40 in the side wall 25 of the urethane pad 20 is pulled inward in the seat width direction due to the bending of the side wall 26 of the skin material 22, and Even when the side periphery 42A is somewhat crushed, as shown in FIG. 3, when the seat cushion 14 is moved to the uppermost position, the side wall portion 26 of the skin material 22 due to the collapse of the lower side periphery 42A of the recess 40 and the cover A gap between the upper wall 24A and the tip 24B of the upper wall 24A is less likely to occur.
　（作用及び効果）
　次に、本実施形態の作用及び効果について説明する。
　車両用座席１０では、図５に示すように、シート本体１２のシートクッション１４が、昇降機構１０Ｃを介して左右一対のスライドレール１０Ａのアッパーレール１０Ｂに対して上下方向へ移動する。このとき、図１～図３に示すように、アッパーレール１０Ｂに固定され、シートクッション１４のシート幅方向外側下部を覆うカバー２４の上壁部２４Ａの先端２４Ｂと、シートクッション１４の外周部に設けられた表皮材２２の側壁部２６とが干渉する。 (Function and effect)
Next, the operation and effect of this embodiment will be described.
In the vehicle seat 10, as shown in FIG. 5, the seat cushion 14 of the seat body 12 moves in the vertical direction with respect to the upper rail 10B of the pair of left and right slide rails 10A via the lifting mechanism 10C. At this time, as shown in FIG. 1 to FIG. 3, it is fixed to the upper rail 10B and covers the front end 24B of the upper wall portion 24A of the cover 24 that covers the lower portion of the seat cushion 14 in the seat width direction, The side wall portion 26 of the provided skin material 22 interferes.
　この際、上記構成の本実施形態では、表皮材２２に覆われたウレタンパッド２０の側壁部２５における、表皮材２２の側壁部２６と、カバー２４の上壁部２４Ａの先端２４Ｂとが干渉する部位に、シート幅方向内側へ凹んだ凹部４０が形成されている。また、この凹部４０は、図２に示すように、シートクッション１４が最も低い位置まで下降した状態では、上壁部４０Ａがカバー２４の上壁部２４Ａの上方近傍の位置となっている。一方、図３に示すように、シートクッション１４が最も高い位置まで上昇した状態では、下壁部４０Ｂが、カバー２４の上壁部２４Ａの下方近傍の位置となっている。そして、凹部４０はカバー２４の上壁部２４Ａに対向してシートクッション１４の前後方向に沿って延設されており、凹部４０の周囲４２は、凹部４０に対してシート幅方向外側に突出している。 At this time, in the present embodiment having the above configuration, the side wall portion 26 of the skin material 22 and the front end 24B of the upper wall portion 24A of the cover 24 interfere with each other in the side wall portion 25 of the urethane pad 20 covered with the skin material 22. A recess 40 that is recessed inward in the sheet width direction is formed at the site. Further, as shown in FIG. 2, in the state in which the seat cushion 14 is lowered to the lowest position, the upper wall portion 40 </ b> A is located near the upper portion of the upper wall portion 24 </ b> A of the cover 24. On the other hand, as shown in FIG. 3, in a state where the seat cushion 14 is raised to the highest position, the lower wall portion 40 </ b> B is a position near the lower portion of the upper wall portion 24 </ b> A of the cover 24. The recess 40 is extended along the front-rear direction of the seat cushion 14 so as to face the upper wall portion 24A of the cover 24, and the periphery 42 of the recess 40 protrudes outward in the seat width direction with respect to the recess 40. Yes.
　このため、シート本体１２のシートクッション１４が上下方向へ移動する際に、カバー２４の上壁部２４Ａの先端２４Ｂとの干渉により、表皮材２２の側壁部２６が弾性変形によりシート幅方向内側へ撓むが、表皮材２２の側壁部２６が、カバー２４の上壁部２４Ａの先端２４Ｂとウレタンパッド２０の側壁部２５との間に挟まれて圧痕が発生することはない。この結果、シートクッション１４の上下移動によりシートクッション１４の側壁部の外観品質が低下するのを防止できる。 For this reason, when the seat cushion 14 of the seat body 12 moves in the vertical direction, the side wall portion 26 of the skin material 22 is elastically deformed to the inner side in the seat width direction due to interference with the tip 24B of the upper wall portion 24A of the cover 24. The side wall portion 26 of the skin material 22 is sandwiched between the tip 24B of the upper wall portion 24A of the cover 24 and the side wall portion 25 of the urethane pad 20, but no indentation is generated. As a result, it is possible to prevent the appearance quality of the side wall portion of the seat cushion 14 from being deteriorated by the vertical movement of the seat cushion 14.
　また、本実施形態では、ウレタンパッド２０の側壁部２５における凹部４０の下方側周囲４２Ａが、凹部４０の上方側周囲４２Ｂに比べてシート幅方向外側へ大きく突出しており、下方側周囲４２Ａの肉厚Ｍ１が上方側周囲４２Ｂの肉厚Ｍ２より大きくなっている（Ｍ１＞Ｍ２）。このため、シートクッション１４が上昇した状態で、表皮材２２の側壁部２６の撓みにより、ウレタンパッド２０の側壁部２５における凹部４０の下方側周囲４２Ａがシート幅方向内側へ引っ張られた際に、凹部４０の下方側の周囲４２Ａが多少潰れても、図３に示すように、（シートクッション１４が最上位置に移動した際に、）凹部４０の下方側周囲４２Ａの潰れによる、表皮材２２の側壁部２６と、カバー２４の上壁部２４Ａの先端２４Ｂとの間の隙間が発生し難くなっている。この結果、シートクッション１４の上下移動によりシートクッション１４の側壁部の外観品質が低下するのをさらに防止できる。 In the present embodiment, the lower periphery 42A of the recess 40 in the side wall 25 of the urethane pad 20 protrudes more outward in the sheet width direction than the upper periphery 42B of the recess 40, and the meat of the lower periphery 42A The thickness M1 is larger than the thickness M2 of the upper periphery 42B (M1> M2). For this reason, when the seat cushion 14 is raised and the lower side periphery 42A of the recess 40 in the side wall portion 25 of the urethane pad 20 is pulled inward in the seat width direction due to the bending of the side wall portion 26 of the skin material 22, Even if the periphery 42A on the lower side of the recess 40 is somewhat crushed, as shown in FIG. 3 (when the seat cushion 14 is moved to the uppermost position), A gap between the side wall portion 26 and the tip 24B of the upper wall portion 24A of the cover 24 is hardly generated. As a result, it is possible to further prevent the appearance quality of the side wall portion of the seat cushion 14 from being deteriorated due to the vertical movement of the seat cushion 14.
