Description

本発明は、サイドエアバックが設けられた車両のシートに装着されるシートカバーに関する。   The present invention relates to a seat cover attached to a vehicle seat provided with a side airbag.

従来、この種のものとして、複数の表皮材を縫製してシートバックを覆う表皮カバーが形成され、該表皮カバーの所定の縫製部に設定された開裂部位が、外部に飛び出すエアバックにより押し破られる構造であって、前記所定の縫製部における開裂部位では表皮材の各端部がそのまま縫製され、他の部位では表皮材の各端部が折り返された状態で縫製されており、開裂部位における縫製強度が相対的に他の部位よりも弱まることとなり、該開裂部位がエアバックにより簡単に押し破られるように構成した表皮カバー(例えば特許文献1)がある。   Conventionally, as this type, a skin cover that covers a seat back is formed by sewing a plurality of skin materials, and a cleavage site set in a predetermined sewing portion of the skin cover is pushed and broken by an airbag that protrudes to the outside. Each end portion of the skin material is sewn as it is at the cleavage site in the predetermined sewing portion, and is sewn in a state where each end portion of the skin material is folded back at the other site. There is a skin cover (for example, Patent Document 1) configured such that the sewing strength is relatively weaker than other parts, and the cleavage part is easily pushed and broken by an airbag.

また、衝撃に起因して作動、膨張するエアバック装置を付帯した自動車の座席を覆って装着する自動車用座席カバーであって、複数の布片を縫製縁で相互に縫製して、この座席カバーを装着する座席にそった形状に成形してなり、縫製縁の一部を、他の縫製縁の縫製糸より伸度が低く、耐衝撃強度の弱い縫製糸で縫製して耐衝撃強度が他の部位に比して弱められた易破断縁によって形成することで、エアバックが作動、膨張する際に、前記易破断縁が優先的に破断して、エアバックの作動、膨張を阻害しない易破断構造とした自動車用座席カバー(例えば特許文献2)がある。   A seat cover for an automobile that covers and attaches an automobile seat attached to an airbag device that operates and expands due to an impact, and a plurality of pieces of cloth are sewn together at a sewing edge, and the seat cover The part of the sewing edge is sewn with a sewing thread whose elongation is lower than that of the other sewing edge and weak impact strength. When the airbag is activated and inflated, the easily breakable edge is preferentially broken when the airbag is operated and inflated, so that the operation and expansion of the airbag are not hindered. There is an automobile seat cover (for example, Patent Document 2) having a fracture structure.

また、座席背凭れの側面襠部にサイドエアバックが内蔵された自動車座席を覆うカバーであって、背凭れカバーの前面カバー部に対し側面襠カバー部を切離し、前面カバー部に係合受け部を備えると共に、この係合受け部に対し係脱可能に係合する係合部を側面襠カバー部に備え、サイドエアバックの飛び出しで上記係合が外れるように設定した座席用カバー(例えば特許文献3)がある。   A cover for covering an automobile seat with a side airbag built into a side heel of the seat back, the side heel cover being separated from the front cover of the back cover, and an engagement receiving portion being provided on the front cover And a seat cover (e.g., a patent) that includes an engaging portion that is detachably engaged with the engagement receiving portion, and is set so that the engagement is released when the side airbag protrudes. There is literature 3).

さらに、エアバックをバックパッドの開口部より膨張展開可能に配置し、エアバック装置の配置側を被包するトリムカバーの縫い目からエアバックの膨張展開に伴うトリムカバーの破断部を形成すると共に、片端末をトリムカバーの破断部となる縫い目で共縫いし、他端末をバックフレームに巻込み止着する力布を縫い目の破断促進手段として備えるもので、エアバックの各バック部分が膨張する方向に合わせて二股状に分かれる力布をバックケースの蓋上に配設し、バックケースの蓋が開放動きするに伴って各バック部分の膨張圧が力布の各端末を共縫いした縫い目の局部に集中するため、トリムカバーの破断部となる縫い目が各局部より速やかに切れ出し、エアバックの各バック部分を座者の頭部方向に向け、また、座者の腰部方向に向けて効果的に膨張展開させる車両用シート(例えば特許文献4)がある。   Further, the airbag is arranged so as to be inflatable and deployable from the opening of the back pad, and a trim cover breakage portion is formed along with the inflation and deployment of the airbag from the seam of the trim cover covering the arrangement side of the airbag device. One end is co-sewn with the seam that becomes the breakage part of the trim cover, and the other end is wound around the back frame and is provided with a force cloth as means for promoting breakage of the seam. A seam that is split into two forks is arranged on the back case lid, and the expansion pressure of each back part is sewn together with each end of the force cloth as the back case lid moves open. Therefore, the seam that becomes the break part of the trim cover cuts out quickly from each local part, and each back part of the airbag is directed toward the head of the seat and toward the waist of the seat. There is a vehicle seat to effectively inflate and deploy (for example, Patent Document 4) Te.

そして、図3及び図5などに示すように、下の上縁部55U,56U側と上の下縁部54S,54S側の重ね合わせ部分57,58は、側面部側より中央側が広い。これにより、側面部側縁部54K,55K側の重なり長さが、中央側縁部54M,55M側の重なり長さより短く、また、側面部側縁部55K,56K側の重なり長さが、中央側縁部55M,56M側の重なり長さより短く設定され、前記縫着部箇所63では重ね合されていない。尚、前記縫着部箇所63は、前記上縁部55U,56U及び下縁部54S,55Sの側面部43側の端部である。   As shown in FIGS. 3 and 5, the overlapping portions 57 and 58 on the lower upper edge portions 55 </ b> U and 56 </ b> U and the upper lower edge portions 54 </ b> S and 54 </ b> S are wider on the center side than on the side surface portion side. Thereby, the overlap length on the side surface side edge portions 54K, 55K side is shorter than the overlap length on the center side edge portion 54M, 55M side, and the overlap length on the side surface side edge portions 55K, 56K side is It is set shorter than the overlapping length on the side edge portions 55M, 56M side, and is not overlapped at the sewing portion portion 63. The sewing portion 63 is an end of the upper edge portions 55U and 56U and the lower edge portions 54S and 55S on the side surface portion 43 side.

尚、図5の説明図では、理解を容易にするため、側面部側生地52の外側及び中央側の縁部と、縫着部53,59とを離して図示しているが、実際には、縫着部53,59は、側面部側生地52の外側及び中央側の縁部の位置に設けられている。   In the explanatory view of FIG. 5, for easy understanding, the outer side and center side edges of the side portion side fabric 52 and the sewn portions 53 and 59 are illustrated separately. The sewing parts 53 and 59 are provided at the positions of the outer side and the center side of the side part side fabric 52.

前記上,中,下の側面部側分割生地54,55,56の前記側面部側縁部54K,55K,56Kは、右側の前記側面部43の前縁に、前記縫着部53により、3枚連続して縫着されている。即ち、前記縫着部53は上の側面部側縁部54Kの上端から下の側面部側縁部56Kの下端まで連続して形成されている。   The side surface side edge portions 54K, 55K, and 56K of the upper, middle, and lower side surface side divided fabrics 54, 55, and 56 are 3 by the sewing portion 53 at the front edge of the right side surface portion 43. It is sewn continuously. That is, the sewing portion 53 is continuously formed from the upper end of the upper side surface side edge portion 54K to the lower end of the lower side surface portion side edge portion 56K.

また、前記上,中,下の側面部側分割生地54,55,56の前記中央側縁部54M,55M,56Mは、下の上縁部55U側に上の下縁部54S側を重ね合わせると共に、下の上縁部56U側に上の下縁部55S側を重ね合わせた状態で、前記中央側生地51の縁に、中央側縫着部59により、3枚連続して縫着されている。即ち、前記縫着部59は上の中央側縁部54Mの上端から下の側面部側縁部56Kの下端まで連続して形成されている。   The center side edge portions 54M, 55M, and 56M of the upper, middle, and lower side surface side divided fabrics 54, 55, and 56 overlap the upper lower edge portion 54S side with the lower upper edge portion 55U side. At the same time, the upper lower edge portion 55S is overlapped with the lower upper edge portion 56U, and three pieces are continuously sewn to the edge of the central side fabric 51 by the central side sewing portion 59. Yes. That is, the sewing portion 59 is continuously formed from the upper end of the upper central side edge portion 54M to the lower end of the lower side surface side edge portion 56K.

この場合、前記重ね合わせ部分57,58において、下の上縁部55U,56U側と上の下縁部54S,55S側とは、横方向の縫着部により縫着されていない。このように上下に隣り合う上,中,下の側面部側分割生地54,55,56同士は縫着されていない。   In this case, in the overlapping portions 57 and 58, the lower upper edge portions 55U and 56U side and the upper lower edge portions 54S and 55S side are not sewn by the lateral sewing portions. Thus, the upper, middle, and lower side surface side divided fabrics 54, 55, and 56 adjacent to each other in the vertical direction are not sewn together.

サイドエアバック31に対応する前記中の側面部側分割生地55は、前記表皮材26に対応するが、表皮材26より幅狭でもよく、その左右幅が50〜250mm(50mm以上、250mm以下)程度、好ましくは、100〜200mm程度がサイドエアバック31の展開を容易にする点で好ましい。   The inside side portion side divided fabric 55 corresponding to the side airbag 31 corresponds to the skin material 26, but may be narrower than the skin material 26, and its left-right width is 50 to 250 mm (50 mm or more, 250 mm or less). The degree, preferably about 100 to 200 mm is preferable in terms of facilitating the development of the side airbag 31.

前記左の側面部側生地52Aの中央側縁部たる右縁は、縫着部により前記中央側生地51の左縁に縫着され、前記左の側面部側生地52Aの側面部側縁部たる左縁は、縫着部により左の側面部43の前縁に縫着されている。   The right edge, which is the center side edge of the left side surface side fabric 52A, is sewn to the left edge of the center side fabric 51 by the sewing portion, and is the side surface side edge of the left side surface side fabric 52A. The left edge is sewn to the front edge of the left side surface portion 43 by a sewn portion.

前記縫着部53は、開裂部位であり、この縫着部53以外の縫着部59・・・は、全て通常の縫着強度で縫着されており、シートバック4の長期使用によっても破れないようになっている。これに対し、前記縫着部53の縫着自体の基本的強度は、中央側縫着部59を含む他の縫着部よりも弱く設定されている。前記他の縫着部よりも前記縫着部53を弱くする手法として、糸の径、糸の断面形状、糸の伸度、縫製ピッチなどを設定することなどが例示され、それらの手法を単独で或いは組み合わせて用いてもよい。尚、以下の各実施例の開裂部位や、縫着部の強度を変える場合などにも同じ手法を用いることができる。   The sewn portion 53 is a cleavage site, and the sewn portions 59 other than the sewn portion 53 are all sewn with a normal sewn strength, and can be torn even when the seat back 4 is used for a long time. There is no such thing. On the other hand, the basic strength of the sewing itself of the sewing part 53 is set to be weaker than other sewing parts including the center side sewing part 59. Examples of a technique for making the sewing part 53 weaker than the other sewing parts include setting a thread diameter, a thread cross-sectional shape, a thread elongation, a sewing pitch, and the like. Or may be used in combination. The same method can also be used when changing the cleavage site of each of the following embodiments or the strength of the sewn portion.

次に、前記シートカバー41の作用について説明する。車体側に装備された衝撃センサー(図示せず)が衝突に伴って作動し、衝撃センサーから出力信号がインフレータに送信されると、インフレータより膨張ガスが発生することから、エアバック本体32がインフレータの出力圧を受けて膨張展開する。   Next, the operation of the seat cover 41 will be described. When an impact sensor (not shown) mounted on the vehicle body operates in response to a collision and an output signal is transmitted from the impact sensor to the inflator, inflation gas is generated from the inflator. In response to the output pressure, it expands and deploys.

エアバック本体32が前方に膨張するに際し、エアバック本体32により縫着部53が開裂し、この開裂により、互いに縫着されていない下縁部54Sと上縁部55Uとが速やかに開くと共に、互いに縫着されていない下縁部55Sと上縁部56Uとが速やかに離れて開き、中の側面部側分割生地55が捲れるように展開するため、エアバック本体32がスムーズに膨張することができる。   When the airbag main body 32 is inflated forward, the sewing portion 53 is cleaved by the air bag main body 32, and the lower edge portion 54S and the upper edge portion 55U that are not sewn together quickly open by this cleavage, Since the lower edge portion 55S and the upper edge portion 56U that are not sewn to each other open quickly and expand so that the inner side surface side divided fabric 55 is rolled, the airbag main body 32 is inflated smoothly. Can do.

このように本実施例では、請求項1に対応して、サイドエアバック31を備えた車両のシート1に装着されるシートカバー41であって、側面部43,43と前面部42と背面部44とを有し、前面部42は車両上下方向に延びる複数の生地たる中央側生地51及び側面部側生地52,52Aから構成されており、複数の生地のうち側面部側生地52が更に上下方向に並んだ複数の側面部側分割生地54,55,56により構成されており、サイドエアバック31は側面部43と側面部側分割生地55との縫着部53を開裂して飛び出す構造となっており、側面部側分割生地54,55,56は、側面部43と前面部42の他の生地たる中央側生地51と縫着されており、上下に隣り合う側面部側分割生地54,55,56の縁部たる下縁部54S,55Sと上縁部55U,56Uが重ね合された状態で側面部側分割生地54,55,56同士縫着されていないから、サイドエアバック31の前面部への展開が容易となる。 Thus, in this embodiment, corresponding to claim 1, the seat cover 41 is mounted on the seat 1 of the vehicle including the side airbag 31, and includes the side surface portions 43, 43, the front surface portion 42, and the back surface portion. 44, and the front portion 42 is composed of a plurality of central side fabrics 51 and side portion side fabrics 52, 52A extending in the vertical direction of the vehicle. A plurality of side surface side divided fabrics 54, 55, 56 arranged in the direction, and the side airbag 31 has a structure in which the sewn portion 53 between the side surface portion 43 and the side surface side side divided fabric 55 is cleaved and protruded. The side portion side divided fabrics 54, 55, 56 are sewn with the central side fabric 51, which is another fabric of the side portion 43 and the front portion 42, and the side portion side divided fabrics 54, which are adjacent to each other in the vertical direction, Lower edge of 55, 56 4S, since 55S and the upper edge 55 U, the side portion side divided dough 54, 55, 56 to each other in a state where 56U is superposed not sewn, expansion into the front portion of the side airbag 31 is facilitated .

このように本実施例では、請求項3に対応して、側面部側分割生地54,55,56同士の重ね合わせ部は、前面部42側が側面部43側よりも長いため、側面部側生地52の破断を容易としている。 Thus, in the present embodiment, in correspondence with claim 3, the overlapping portion of the side surface side divided fabrics 54, 55, 56 is longer on the front surface 42 side than on the side surface 43 side. 52 is easy to break.

尚、実施例では、複数の側面部側分割生地54,55,56に縦方向の縫着部53を設けたが、サイドエアバック31は側面部43と側面部側分割生地55との縫着部53を開裂して飛び出す構成を採用しているから、側面部側分割生地55のみに、縫着部59より強度の弱い縫着部53を設け、側面部側分割生地55との重なり部分を除いて他の側面部側分割生地54,56には縫着部53より強い縫着部を設けてもよい。   In the embodiment, the plurality of side surface side divided fabrics 54, 55, 56 are provided with the vertical sewing portions 53, but the side airbag 31 is sewn between the side surface portion 43 and the side surface portion side divided fabric 55. Since the configuration in which the portion 53 is cleaved and popped out is employed, only the side surface side divided fabric 55 is provided with the sewing portion 53 having a lower strength than the sewing portion 59, and the overlapping portion with the side surface side divided fabric 55 is provided. Except for this, the other side surface side divided fabrics 54 and 56 may be provided with a sewn portion stronger than the sewn portion 53.

このように本実施例では、請求項に対応して、側面部側生地52は、3枚の側面部側分割生地54,55,56で構成されているから、サイドエアバック31の飛び出し部位と開裂部位を略対応させることができる。 Thus, in this embodiment, the side portion side fabric 52 is composed of the three side portion side divided fabrics 54, 55, and 56 in correspondence with the fifth aspect. Can substantially correspond to the cleavage site.

実施例上の効果として、縫着部箇所63を除いて上部の側面部側分割生地54,55の下縁部54S,55Sを下部の側面部側分割生地55,56の上縁部55U,56Uに重ね合わせたから、上縁部55U,56Uに引っ掛かり難く、また、上縁部55U,56Uの内面側から埃がシートカバー41の内部に入ることもない。   As an effect of the embodiment, the lower edge portions 54S and 55S of the upper side portion side divided fabrics 54 and 55 except the sewing portion 63 are used as the upper edge portions 55U and 56U of the lower side portion side divided fabrics 55 and 56, respectively. Therefore, the dust does not easily catch on the upper edge portions 55U and 56U, and dust does not enter the seat cover 41 from the inner surface side of the upper edge portions 55U and 56U.

また、下の上縁部55U,56U側と上の下縁部54S,54S側の重ね合わせ部分57,58を設け、縫着部箇所63では重ね合されていないから、縫着部53の糸は一度に途切れずに破断して縫着部53が開裂し、下縁部54Sと上縁部55Uとが速やかに開くと共に、下縁部55Sと上縁部56Uとが速やかに離れて開き、中の側面部側分割生地55が展開してサイドエアバック31を円滑に展開することができる。そして、縫着部箇所63で、重ね合わせ部分があると、この部分の剛性が他に比べて高くなり、その重ね合わせ部分で破断が途切れる虞があるが、縫着部箇所63では重ね合されていないから、縫着部53の糸が一度に途切れずに破断して開裂する。さらに、側面部側分割生地55の左右幅が50mm以上、好ましくは100mm以上であるから、側面部側分割生地55部分が大きく開き、サイドエアバック31の展開が円滑に行われる。   Further, since the overlapping portions 57 and 58 on the lower upper edge portions 55U and 56U and the upper lower edge portions 54S and 54S are provided and are not overlapped at the sewing portion 63, the thread of the sewing portion 53 is provided. Breaks without interruption at one time, the sewn portion 53 is cleaved, the lower edge portion 54S and the upper edge portion 55U open quickly, and the lower edge portion 55S and the upper edge portion 56U open quickly apart, The side surface side division | segmentation dough 55 inside can expand | deploy and the side airbag 31 can be expand | deployed smoothly. If there is an overlapped portion at the sewing portion 63, the rigidity of this portion becomes higher than the others, and there is a possibility that breakage may be interrupted at the overlapped portion. Therefore, the thread of the sewn portion 53 breaks and splits without interruption at a time. Furthermore, since the lateral width of the side portion side divided fabric 55 is 50 mm or more, preferably 100 mm or more, the side portion side divided fabric 55 portion opens widely, and the side airbag 31 is smoothly deployed.
