特許文献１は、従来のＡピラーガーニッシュ取付け装置を開示している。
従来の頭部保護エアバッグ装置５では、図１１〜図１３に示すように、窓等の開口の周縁におけるＡピラー１とルーフサイドレール２とにわたって、カーテンシールドエアバッグ（通称、カーテンエアバッグ）３がロール折りまたは蛇腹状に畳まれて収納されている。車両衝突時、カーテンシールドエアバッグ（以下、単にＣＳＡともいう）３が図１１の２点鎖線に示すように展開膨張する時に、ＣＳＡ３を車内側から覆っていた、Ａピラー部のＡピラーガーニッシュ４、およびルーフサイドレール部のルーフヘッドライニングが、ＣＳＡ３によって車内側に押されてパネル部材１ａから離間し（離間状態のＡピラーガーニッシュを図１２で２点鎖線４’で示す）、Ａピラーガーニッシュ４’およびルーフヘッドライニングと、パネル部材１ａとの間に間隔が形成され、該間隔を通って、ＣＳＡ３が車室内に窓に沿って展開膨張し（展開状態のＣＳＡの一部を図１２において２点鎖線３’で示す）、乗員頭部を保護する。 Patent document 1 is disclosing the conventional A pillar garnish attachment apparatus.
In the conventional head protection airbag device 5, as shown in FIGS. 11 to 13, a curtain shield airbag (commonly known as a curtain airbag) extends over the A pillar 1 and the roof side rail 2 at the periphery of the opening of a window or the like. 3 is folded and stored in a roll fold or bellows shape. At the time of a vehicle collision, when the curtain shield airbag (hereinafter also simply referred to as CSA) 3 is deployed and inflated as shown by a two-dot chain line in FIG. 11, the A pillar garnish 4 of the A pillar portion that covers the CSA 3 from the inside of the vehicle. And the roof head lining of the roof side rail portion is pushed away from the panel member 1a by the CSA 3 (the separated A pillar garnish is indicated by a two-dot chain line 4 'in FIG. 12), and the A pillar garnish 4 A space is formed between the roof head lining and the panel member 1a, and through this space, the CSA 3 expands and expands along the window in the vehicle interior (a part of the expanded CSA is 2 in FIG. 12). Protects the passenger's head.

従来のＡピラーガーニッシュ４のＡピラー１部位のパネル部材（インナーパネル）１ａへの取付け装置５は、通常、図１２および図１３に示す構造をとる。
従来装置では、Ａピラーガーニッシュ４は、テザークリップ６を用いて、Ａピラー１のパネル部材１ａに取付けられる。テザークリップ６とＡピラーガーニッシュ４は樹脂製部品であり、パネル部材１ａは鋼板製部品である。 The attachment device 5 to the panel member (inner panel) 1a of the A pillar 1 portion of the conventional A pillar garnish 4 normally has the structure shown in FIGS.
In the conventional apparatus, the A pillar garnish 4 is attached to the panel member 1 a of the A pillar 1 using the tether clip 6. The tether clip 6 and the A pillar garnish 4 are resin parts, and the panel member 1a is a steel plate part.

テザークリップ６は、パネル部材１ａへの装着部であるボデー装着部６ａと、Ａピラーガーニッシュ４への装着部であるガーニッシュ装着部６ｂと、テザークリップ先端部に形成されたアンカー部６ｄと、ガーニッシュ装着部６ｂとアンカー部６ｄとの間にわたって延びるテザー部６ｃとを有している。 The tether clip 6 includes a body mounting portion 6a which is a mounting portion to the panel member 1a, a garnish mounting portion 6b which is a mounting portion to the A pillar garnish 4, an anchor portion 6d formed at the tip of the tether clip, and a garnish A tether portion 6c extending between the mounting portion 6b and the anchor portion 6d is provided.

Ａピラーガーニッシュ４は、Ａピラー長手方向（図１１のＡ方向）に延びるガーニッシュ本体７と、ガーニッシュ本体７の裏面（乗員から見て裏側の面）に一体に形成された台座部８を有する。台座部８は、頂壁８ａと、頂壁８ａとガーニッシュ本体７の裏面とを連結する、互いに対向する側壁８ｂ、８ｃと、側壁８ｂ、８ｃに直交するもう一つの側壁（図１２、図１３には表れない）を有する。側壁８ｂ、８ｃのうち一方の側壁８ｂは、台座部８の頂壁８ａに直交する方向に延びる。側壁８ｂ、８ｃのうち他方の側壁８ｃは台座部８の頂壁８ａに対して斜め方向（ガーニッシュ本体７に近づくにつれて側壁８ｂ、８ｃの間隔を拡げる方向）に延びる。台座部８内の空間部は、テザークリップ６のテザー部６ｃとアンカー部６ｄを収容する収容空間部であり、側壁８ｃの傾斜により、ガーニッシュ本体７に近づくにつれてＡピラー長手方向と直交する方向の収容空間部幅が拡大している。ＣＳＡ３は、台座部８の収容空間部の外側に、かつ、傾斜された側壁８ｃの外側に、Ａピラー長手方向に延びるように、配置される。ＣＳＡ３は、展開時に、Ａピラーガーニッシュ４を内側から押し広げて図１２の４’の状態にし、展開間隔を通って車室内に展開、膨張し、図１１の３’の状態になる。 The A-pillar garnish 4 has a garnish body 7 extending in the A-pillar longitudinal direction (A direction in FIG. 11), and a pedestal portion 8 that is integrally formed on the back surface of the garnish body 7 (the back surface as viewed from the occupant). The pedestal portion 8 is connected to the top wall 8a, the top wall 8a and the back surface of the garnish main body 7, opposite side walls 8b and 8c, and another side wall orthogonal to the side walls 8b and 8c (FIGS. 12 and 13). Does not appear in). One of the side walls 8 b and 8 c extends in a direction perpendicular to the top wall 8 a of the pedestal portion 8. Of the side walls 8b and 8c, the other side wall 8c extends obliquely with respect to the top wall 8a of the pedestal portion 8 (a direction in which the distance between the side walls 8b and 8c increases as the garnish body 7 is approached). The space portion in the pedestal portion 8 is a housing space portion that accommodates the tether portion 6c and the anchor portion 6d of the tether clip 6, and in a direction orthogonal to the longitudinal direction of the A pillar as it approaches the garnish body 7 due to the inclination of the side wall 8c. The width of the accommodating space is enlarged. The CSA 3 is arranged on the outside of the housing space portion of the base portion 8 and on the outside of the inclined side wall 8c so as to extend in the longitudinal direction of the A pillar. At the time of deployment, the CSA 3 pushes and spreads the A pillar garnish 4 from the inside to a state 4 'in FIG. 12, expands and expands into the vehicle interior through the deployment interval, and enters a state 3' in FIG.

ＣＳＡ展開前は、テザークリップ６は、ガーニッシュ装着部６ｂでＡピラーガーニッシュ４の台座部８の頂壁８ａに形成された矩形孔９に嵌合している。ＣＳＡ展開中には、Ａピラーガーニッシュ４がＣＳＡ３に押されてＡピラーパネル部材１ａから離れる方向に移動し、台座部８の頂壁８ａは、テザークリップ６のガーニッシュ装着部６ｂからアンカー部６ｄ側に、テザークリップ６に対して相対的に移動する。台座部８の頂壁８ａの矩形孔９の周縁部がアンカー部６ｄに係合した時に、Ａピラーガーニッシュ４のＡピラーパネル部材１ａから離れる方向の移動が止まり、Ａピラーガーニッシュ４の乗員側への飛散が抑制される。 Before the CSA is deployed, the tether clip 6 is fitted in a rectangular hole 9 formed in the top wall 8a of the base portion 8 of the A pillar garnish 4 at the garnish mounting portion 6b. During CSA deployment, the A-pillar garnish 4 is pushed by the CSA 3 and moves away from the A-pillar panel member 1a, and the top wall 8a of the pedestal portion 8 is moved from the garnish mounting portion 6b of the tether clip 6 to the anchor portion 6d side. And move relative to the tether clip 6. When the peripheral edge of the rectangular hole 9 in the top wall 8a of the pedestal portion 8 is engaged with the anchor portion 6d, the movement of the A pillar garnish 4 in the direction away from the A pillar panel member 1a stops, and toward the passenger side of the A pillar garnish 4 Is prevented from scattering.

ＣＳＡ展開における、Ａピラーガーニッシュ４とＡピラーボデー部材１ａとの間のＣＳＡ展開用間隔を必要量確保するために、テザー部６ｃは所定の長さをもつ。この所定の長さを持つテザー部６ｃを台座部８内の収容空間部に収容すると、アンカー部６ｄが、Ａピラーガーニッシュ４の側壁８ｂ、８ｃ間部分７ａに干渉し、アンカー部６ｄとテザー部６ｃとを台座部８内の収容空間部内に収容することが困難になる。それを回避するため、従来は、テザークリップ単品ではほぼ真直のテザー部６ｃを、台座部８に形成した案内壁８ｅで案内することにより、Ａピラー１の長手方向と直交する方向に、かつ傾斜する側壁８ｃ側に、曲げて組み付け、このテザー部６ｃが曲がった状態で、アンカー部６ｄとテザー部６ｃとを台座部８内の収容空間部に収容している。Ａピラーガーニッシュ４の台座部８の側壁８ｃを頂壁８ａに対して傾斜させ、台座部８内の収容空間部がガーニッシュ本体７に近づくにつれて側壁８ｂ、８ｃの間隔が拡がっていることは、アンカー部６ｄとテザー部６ｃとを台座部８内の収容空間部内に収容することを容易にしている。 The tether portion 6c has a predetermined length in order to secure a necessary amount of the CSA expansion interval between the A pillar garnish 4 and the A pillar body member 1a in the CSA expansion. When the tether portion 6c having the predetermined length is accommodated in the accommodating space portion in the pedestal portion 8, the anchor portion 6d interferes with the portion 7a between the side walls 8b and 8c of the A pillar garnish 4, and the anchor portion 6d and the tether portion It becomes difficult to accommodate 6c in the accommodation space part in the base part 8. FIG. In order to avoid this, conventionally, the tether portion 6c, which is a substantially straight tether clip, is guided by the guide wall 8e formed on the pedestal portion 8 so as to be inclined in a direction perpendicular to the longitudinal direction of the A pillar 1. The anchor portion 6d and the tether portion 6c are accommodated in the accommodating space portion in the pedestal portion 8 in a state where the tether portion 6c is bent and assembled to the side wall 8c side. The side wall 8c of the pedestal portion 8 of the A pillar garnish 4 is inclined with respect to the top wall 8a, and the distance between the side walls 8b and 8c increases as the accommodating space in the pedestal portion 8 approaches the garnish body 7. It is easy to accommodate the portion 6d and the tether portion 6c in the accommodating space portion in the pedestal portion 8.

しかし、特許文献１のＡピラーガーニッシュ取付け装置５にはつぎの課題がある。
テザークリップ６のテザー部６ｃがＡピラー１の長手方向と直交する方向に曲げられ、アンカー部６ｄと曲げられたテザー部６ｃを収容するために、Ａピラーガーニッシュ４の台座部８の１つの側壁８ｃが、Ａピラー１の長手方向と直交する方向にかつガーニッシュ本体７に近づくにつれて側壁８ｂ、８ｃ間隔が拡がるように、頂壁８ａに対して傾斜されているため、図１２に示すように、台座部８の高さ方向の中間部位での、台座部８の、収容空間部幅Ｄｐが、増大する。その結果、運転者から見た方向（図１２のＢ方向）において、運転者から見た方向と直交する方向の、台座部８の高さ方向の中間部位での、台座部８とＣＳＡ３との幅寸法Ｗｐが、テザー部６ｃが曲げられない場合に比べて、増大し、それにつれてＡピラーの、運転者から見た方向と直交する方向の、幅も増大する。運転者の視界はＡピラーの幅分遮られ、Ａピラーの幅の増大は視界を低下させるので、テザー部６ｃが曲げられて取り付けられる従来のＡピラーガーニッシュ取付け装置には、視界上、改善の余地がある。図１２は、助手席側のＡピラーを示しているが、運転席側もこれに準じた課題がある。 However, the A pillar garnish attaching device 5 of Patent Document 1 has the following problems.
One side wall of the pedestal portion 8 of the A pillar garnish 4 is accommodated so that the tether portion 6c of the tether clip 6 is bent in a direction perpendicular to the longitudinal direction of the A pillar 1 and the anchor portion 6d and the bent tether portion 6c are accommodated. Since 8c is inclined with respect to the top wall 8a so that the distance between the side walls 8b and 8c increases as it approaches the garnish body 7 in a direction orthogonal to the longitudinal direction of the A pillar 1, as shown in FIG. The accommodation space width Dp of the pedestal portion 8 at the intermediate portion in the height direction of the pedestal portion 8 increases. As a result, in the direction seen from the driver (direction B in FIG. 12), the pedestal 8 and the CSA 3 at the intermediate portion in the height direction of the pedestal 8 in the direction orthogonal to the direction seen from the driver. The width dimension Wp increases as compared with the case where the tether portion 6c is not bent, and accordingly, the width of the A pillar in the direction perpendicular to the direction seen from the driver also increases. The driver's field of view is blocked by the width of the A pillar, and the increase in the width of the A pillar reduces the field of view. Therefore, the conventional A pillar garnish mounting device in which the tether portion 6c is bent and mounted is improved in view. There is room. Although FIG. 12 shows the A-pillar on the passenger seat side, the driver seat side has a problem corresponding to this.

本発明の目的は、Ａピラーの幅を、従来（台座部が頂壁に直交する側壁と頂壁に斜交する側壁とからなる対向側壁を有し、テザークリップのテザー部がＡピラーの長手方向と直交する方向に曲げられて台座部内に配置される場合のＡピラーの幅）に比べて狭くし、視界を改善したＡピラーガーニッシュ取付け装置を提供することにある。 An object of the present invention is to provide a width of the A pillar, which is conventionally (the pedestal portion has an opposite side wall composed of a side wall orthogonal to the top wall and a side wall oblique to the top wall, and the tether portion of the tether clip is the longitudinal length of the A pillar. It is an object to provide an A-pillar garnish attachment device that is narrower than the width of the A-pillar when bent in a direction orthogonal to the direction and disposed in a pedestal portion, and has improved visibility.

上記課題を解決する、または上記目的を達成する本発明のＡピラーガーニッシュ取付け装置はつぎのとおりである。 The A-pillar garnish attaching device of the present invention that solves the above problems or achieves the above object is as follows.

（１）本発明のＡピラーガーニッシュ取付け装置は、Ａピラーガーニッシュと、車体のＡピラーのパネル部材と、テザークリップとを有し、テザークリップによりＡピラーガーニッシュが車体のＡピラーのパネル部材に取付けられるＡピラーガーニッシュ取付け装置である。
Ａピラーガーニッシュは、Ａピラーの長手方向に延びるガーニッシュ本体と、ガーニッシュ本体の長手方向の一部にガーニッシュ本体の裏面からパネル部材側に突出させて形成された台座部とを有する。
台座部は、クリップ挿通孔を有する頂壁と、該頂壁とガーニッシュ本体とを連結する互いに対向する対向側壁とを有しており、台座部の頂壁と対向側壁とガーニッシュ本体とで囲まれた空間部は、テザークリップの一部を収容する収容空間部を形成している。
テザークリップが、パネル部材への装着部であるボデー装着部と、Ａピラーガーニッシュへの装着部であるガーニッシュ装着部と、テザークリップ先端部に形成されたアンカー部と、ガーニッシュ装着部とアンカー部との間にわたって延びる可撓性があるテザー部とを有している。
テザークリップのテザー部は、少なくとも一部が収容空間部に収容されている。
台座部の対向側壁は、頂壁とガーニッシュ本体とを連結する方向の中間部に、収容空間部内に突出し対向側壁の間隔を狭くするくびれ部を有している。 (1) The A-pillar garnish attachment device of the present invention has an A-pillar garnish, a panel member of the A-pillar of the vehicle body, and a tether clip, and the A-pillar garnish is attached to the panel member of the A-pillar of the vehicle body by the tether clip. A-pillar garnish attachment device.
The A pillar garnish has a garnish main body extending in the longitudinal direction of the A pillar, and a pedestal formed on a part of the garnish main body in the longitudinal direction so as to protrude from the back surface of the garnish main body toward the panel member.
The pedestal part has a top wall having a clip insertion hole and opposing side walls that connect the top wall and the garnish body, and is surrounded by the top wall, the opposing side wall, and the garnish body of the pedestal part. The space portion forms an accommodation space portion for accommodating a part of the tether clip.
A tether clip includes a body mounting portion that is a mounting portion to the panel member, a garnish mounting portion that is a mounting portion to the A-pillar garnish, an anchor portion that is formed at the tip of the tether clip, a garnish mounting portion, and an anchor portion. And a flexible tether portion extending between the two.
At least a part of the tether portion of the tether clip is accommodated in the accommodating space portion.
The opposing side wall of the pedestal portion has a constricted portion that protrudes into the accommodating space and narrows the interval between the opposing side walls at an intermediate portion in a direction in which the top wall and the garnish main body are connected.

（２）台座部の対向側壁は、くびれ部を除いて、互いにほぼ平行でかつ台座部の頂壁に直交している。
テザークリップのテザー部は単品状態で曲がっている。
ＡピラーガーニッシュのＡピラーパネル部材への取付け完了状態で、テザークリップのテザー部は、テザー部の曲がり方向をＡピラーの長手方向に向けられている。 (2) The opposing side walls of the pedestal portion are substantially parallel to each other and perpendicular to the top wall of the pedestal portion except for the constricted portion.
The tether part of the tether clip is bent as a single item.
When the A pillar garnish is attached to the A pillar panel member, the tether portion of the tether clip has the bending direction of the tether portion oriented in the longitudinal direction of the A pillar.

（３）アンカー部は矩形状の外形を有し、アンカー部は該アンカー部の外形の矩形の長手方向を台座部の対向側壁を結ぶ方向に向けられている。
台座部の対向側壁のくびれ部は、収容空間部内に突出する、１つ以上のリブを有する。
台座部の対向側壁のくびれ部のリブの間隔は、アンカー部の外形の矩形の長手方向の寸法以下である。 (3) The anchor portion has a rectangular outer shape, and the anchor portion is oriented in a direction connecting the opposing side walls of the pedestal portion with the rectangular longitudinal direction of the anchor portion.
The constricted part of the opposing side wall of the pedestal part has one or more ribs protruding into the accommodation space part.
The interval between the ribs of the constricted portion of the opposed side wall of the pedestal portion is equal to or smaller than the longitudinal dimension of the outer shape of the anchor portion.

（４）台座部の対向側壁のくびれ部は、部分円筒形状を有する。 (4) The constriction part of the opposing side wall of a base part has a partial cylindrical shape.

（５）台座部の対向側壁のくびれ部は、台形形状を有する。 (5) The constriction part of the opposing side wall of the base part has a trapezoidal shape.

上記（１）のＡピラーガーニッシュ取付け装置によれば、台座部の対向側壁は、頂壁とガーニッシュ本体とを連結する方向の中間部に、収容空間部内に突出し対向側壁の間隔を狭くするくびれ部を有しているので、台座部の対向側壁の外側面は、くびれ部において収容空間部側に凹んだ凹部を形成している。そして、この凹部に、Ａピラーガーニッシュ裏側に配置される部品の一部を進入させて、該部品を、台座部の対向側壁のくびれ部に寄せて配置することにより、Ａピラーを細幅化できる。
たとえば、ＣＳＡの一部（凹部に対向するＣＳＡ部分）が凹部に進入するようにＣＳＡを台座部に寄せて配置することにより、くびれ部以外の部位での台座部の幅ＤとＣＳＡの断面の幅Ｃの和の幅（Ｄ＋Ｃ）が、従来（台座部側壁にくびれ部が形成されない場合）に比べて進入量Ｅ分、狭くなる。その結果、運転者から見た方向Ｂの台座部とＣＳＡの和の幅Ｗが従来のＷｐに比べて狭くなり、それにつれて、運転者から見た方向ＢのＡピラーの幅も、従来装置に比べ、狭くなる。その結果、視界がＡピラーによって遮られにくくなり、視界が改善される。 According to the A-pillar garnish mounting device of (1) above, the opposing side wall of the pedestal portion is a constricted portion that protrudes into the housing space and narrows the interval between the opposing side walls in the intermediate portion in the direction connecting the top wall and the garnish body. Therefore, the outer side surface of the opposing side wall of the pedestal portion forms a concave portion that is recessed toward the accommodation space portion in the constricted portion. A part of the part arranged on the back side of the A pillar garnish is made to enter the recess, and the part is brought close to the constricted part of the opposing side wall of the pedestal part, whereby the A pillar can be narrowed. .
For example, by placing the CSA close to the pedestal so that a part of the CSA (the CSA part facing the recess) enters the recess, the width D of the pedestal at the part other than the constricted part and the cross section of the CSA The width (D + C) of the sum of the widths C becomes narrower by the amount of entry E compared to the conventional case (when the constricted part is not formed on the side wall of the base part). As a result, the width W of the sum of the pedestal portion in the direction B and the CSA viewed from the driver is narrower than the conventional Wp, and accordingly, the width of the A pillar in the direction B viewed from the driver is Compared to narrow. As a result, the field of view is hardly blocked by the A pillar, and the field of view is improved.

上記（２）のＡピラーガーニッシュ取付け装置によれば、テザー部はテザークリップの単品状態ですでに曲がっており、テザー部の曲がり方向がＡピラーの長手方向に向けられているので、テザー部の曲がり方向がＡピラーの長手方向と直交する方向に向けられていた従来装置に比べ、台座部の幅（Ａピラーの長手方向と直交する方向の台座部の寸法）をＤｐからＤに狭くすることができる。また、台座部の幅が狭くなった分、台座部の幅ＤとＣＳＡの断面の幅Ｃの和の幅（Ｄ＋Ｃ）が狭くなる。その結果、運転者から見た方向Ｂの台座部とＣＳＡの和の幅Ｗが従来のＷｐに比べて狭くなり、それにつれて、運転者から見た方向ＢのＡピラーの幅も、従来装置に比べ、狭くなる。その結果、視界がＡピラーによって遮られにくくなり、視界が改善される。 According to the A-pillar garnish attachment device of (2) above, the tether portion is already bent in a single tether clip state, and the bending direction of the tether portion is directed to the longitudinal direction of the A-pillar. The width of the pedestal (the dimension of the pedestal in the direction perpendicular to the longitudinal direction of the A pillar) is narrowed from Dp to D compared to the conventional device in which the bending direction is directed in the direction perpendicular to the longitudinal direction of the A pillar. Can do. Further, the width (D + C) of the sum of the width D of the pedestal portion and the width C of the cross section of the CSA is reduced by the amount by which the width of the pedestal portion is reduced. As a result, the width W of the sum of the pedestal portion in the direction B and the CSA viewed from the driver is narrower than the conventional Wp, and accordingly, the width of the A pillar in the direction B viewed from the driver is Compared to narrow. As a result, the field of view is hardly blocked by the A pillar, and the field of view is improved.

上記（３）のＡピラーガーニッシュ取付け装置によれば、台座部の対向側壁のくびれ部は収容空間部内に突出するリブを有し、該対向側壁のリブの間隔（対向側壁の、一方の側壁のリブと他方の側壁のリブとの間隔）が、アンカー部の外形の矩形の長手方向の寸法以下であるので、ＣＳＡ展開時に、台座部頂壁がアンカー部側に移動する時に、アンカー部が台座部のくびれ部のリブと摺動接触し、その時の摩擦によるエネルギー吸収作用が得られる。
その結果、アンカー部がくびれ部を通り抜けて台座部頂壁のクリップ挿通孔周縁部に衝突する時の衝突力が弱められ、テザー部が（とくに、低温時に）破断することが防止される。これによって、テザー部が破断した場合には生じるかもしれないＡピラーガーニッシュの飛散が抑制される。 According to the A-pillar garnish attachment device of (3) above, the constricted portion of the opposing side wall of the pedestal portion has ribs protruding into the accommodating space, and the interval between the ribs of the opposing side wall (the one side wall of the opposing side wall) The distance between the rib and the rib on the other side wall is equal to or less than the longitudinal dimension of the outer shape of the anchor portion. Therefore, when the pedestal top wall moves to the anchor portion side during CSA deployment, the anchor portion is It comes into sliding contact with the rib of the constricted part of the part, and an energy absorbing action by friction at that time is obtained.
As a result, the collision force when the anchor portion passes through the constricted portion and collides with the peripheral edge portion of the clip insertion hole on the top wall of the pedestal portion is weakened, and the tether portion is prevented from breaking (particularly at low temperatures). This suppresses scattering of the A pillar garnish that may occur when the tether portion is broken.

上記（４）のＡピラーガーニッシュ取付け装置によれば、台座部の対向側壁のくびれ部は、部分円筒形状を有するので、くびれ部の外面の凹部は弧状をなす。一方、ＣＳＡがロール折りの場合は、ＣＳＡの断面の外形がほぼ円形である。したがって、くびれ部の外面の弧状凹部は、外形がほぼ円形のＣＳＡの断面の一部を収容可能である。そのため、台座部の対向側壁のくびれ部が部分円筒形状である場合は、ロール折りのＣＳＡに対して適用されることが望ましい。 According to the A-pillar garnish attachment device of (4) above, the constricted portion of the opposed side wall of the pedestal portion has a partial cylindrical shape, so that the concave portion on the outer surface of the constricted portion forms an arc shape. On the other hand, when the CSA is roll-folded, the outer shape of the cross section of the CSA is substantially circular. Therefore, the arc-shaped concave portion on the outer surface of the constricted portion can accommodate a part of the cross section of the CSA having a substantially circular outer shape. Therefore, when the constriction part of the opposing side wall of a base part is a partial cylindrical shape, it is desirable to apply with respect to roll folding CSA.

上記（５）のＡピラーガーニッシュ取付け装置によれば、台座部の対向側壁のくびれ部は、台形形状を有するので、くびれ部の外面の凹部は台形状をなす。一方、ＣＳＡが蛇腹折りの場合は、ＣＳＡの断面の外形がほぼ矩形である。したがって、くびれ部の外面の台形凹部は、外形がほぼ矩形のＣＳＡの断面の一部を収容可能である。そのため、台座部の対向側壁のくびれ部が台形形状である場合は、蛇腹折りのＣＳＡに対して適用されることが望ましい。 According to the A-pillar garnish attachment device of the above (5), the constricted portion on the opposite side wall of the pedestal portion has a trapezoidal shape, so that the concave portion on the outer surface of the constricted portion has a trapezoidal shape. On the other hand, when the CSA is accordion folded, the outer shape of the cross section of the CSA is substantially rectangular. Therefore, the trapezoidal concave portion on the outer surface of the constricted portion can accommodate a part of the cross section of the CSA having a substantially rectangular outer shape. Therefore, when the constriction part of the opposing side wall of a base part is trapezoid shape, it is desirable to apply with respect to CSA of bellows fold.

In the head protection airbag device including the A-pillar garnish attachment device 10 of the present invention, as shown in FIG. 11, a curtain shield airbag (hereinafter referred to as “curtain shield airbag”) extends across the A-pillar 11 and the roof side rail 12 at the periphery of the opening such as a window. (Also simply referred to as CSA) 13 is housed in a roll fold or a bellows shape. Although FIG. 1 shows the case where the CSA 13 is roll-folded, it may be folded into a bellows shape. In the case of roll folding, the outer shape of the CSA 13 is substantially circular, but when folded in a bellows shape, the outer shape of the CSA 13 is substantially rectangular. At the time of a vehicle collision, when the CSA 13 expands and expands as shown by a two-dot chain line in FIG. 11, the A pillar garnish 30 of the A pillar portion and the roof head lining of the roof side rail portion covering the CSA 13 from the inside of the vehicle. The panel is pushed away from the panel member 40 by the CSA 13, and a space is formed between the A pillar garnish 30 and the roof head lining and the panel member 40. Through this interval, the CSA 13 expands and expands along the window in the passenger compartment to protect the passenger's head. 1 and 11, the expansion and expansion of the CSA 13 is indicated by a two-dot chain line 13 ′. Moreover, in FIG. 1, the A pillar garnish 30 in the middle of the separation from the panel member is indicated by a two-dot chain line 30 ′.

本発明の実施例のＡピラーガーニッシュ取付け装置１０は、テザークリップ２０によりＡピラーガーニッシュ３０が車体のＡピラー１１のパネル部材４０に取付けられるＡピラーガーニッシュ取付け装置である。図１〜９に示すように、Ａピラーガーニッシュ取付け装置１０は、Ａピラーガーニッシュ３０と、車体のＡピラー１１のパネル部材４０（インナーパネル４１を含む）と、テザークリップ２０とを有する。Ａピラーガーニッシュ３０は硬質製樹脂部材であり、テザークリップ２０は軟質製樹脂部材（弾性変形可能な部材）であり、パネル部材４０は鋼板製部材である。 The A pillar garnish attaching device 10 of the embodiment of the present invention is an A pillar garnish attaching device in which the A pillar garnish 30 is attached to the panel member 40 of the A pillar 11 of the vehicle body by the tether clip 20. As shown in FIGS. 1 to 9, the A pillar garnish attaching device 10 includes an A pillar garnish 30, a panel member 40 (including an inner panel 41) of the A pillar 11 of the vehicle body, and a tether clip 20. The A pillar garnish 30 is a hard resin member, the tether clip 20 is a soft resin member (elastically deformable member), and the panel member 40 is a steel plate member.

Ａピラー１１のパネル部材４０は、インナーパネル４１、アウターパネル４２、インナーパネル４１とアウターパネル４２との間に設けられたリーンフォースメント４３を有する。Ａピラーガーニッシュ３０は、テザークリップ２０により、インナーパネル４１に取り付けられる。なお、図１において、４４〜５０の部品は、従来公知のものであり、４４はフロントガラス、４５はドレンホース、４６はアンテナ、４７はワイヤハーネス、４８はウォッシャホース、４９、５０は、ゴム製のウエザーストリップである。 The panel member 40 of the A pillar 11 includes an inner panel 41, an outer panel 42, and a reinforcement 43 provided between the inner panel 41 and the outer panel 42. The A pillar garnish 30 is attached to the inner panel 41 by the tether clip 20. In FIG. 1, the components 44 to 50 are conventionally known, 44 is a windshield, 45 is a drain hose, 46 is an antenna, 47 is a wire harness, 48 is a washer hose, and 49 and 50 are rubber. Made of weather strip.

Ａピラーガーニッシュ３０は、Ａピラー１１の長手方向に延びるガーニッシュ本体３１と、ガーニッシュ本体３１の長手方向の一部にガーニッシュ本体３１の裏面からパネル部材４０側に突出させて形成された台座部３２とを有する。Ａピラーガーニッシュ３０は、Ａピラー１１のパネル部材４０、ＣＳＡ１３、および部品４５〜４８を、車室側から覆う。ＣＳＡ１３は、インナーパネル４１とガーニッシュ本体３１との間の空間部で、台座部３２よりフロントガラス４４から遠い側の空間部に配置される。ＣＳＡ１３は、Ａピラー１１の長手方向に延びる。部品４５〜４８は、台座部３２よりフロントガラス４４側にある。したがって、ＣＳＡ１３が展開膨張する時に、台座部３２および部品４５〜４８は邪魔にならない。 The A pillar garnish 30 includes a garnish main body 31 extending in the longitudinal direction of the A pillar 11, and a pedestal portion 32 formed on a part of the garnish main body 31 in the longitudinal direction so as to protrude from the back surface of the garnish main body 31 toward the panel member 40. Have The A pillar garnish 30 covers the panel member 40, the CSA 13, and the parts 45 to 48 of the A pillar 11 from the passenger compartment side. The CSA 13 is a space portion between the inner panel 41 and the garnish main body 31 and is disposed in a space portion farther from the windshield 44 than the pedestal portion 32. The CSA 13 extends in the longitudinal direction of the A pillar 11. The components 45 to 48 are on the windshield 44 side from the pedestal portion 32. Therefore, when the CSA 13 is deployed and expanded, the pedestal 32 and the parts 45 to 48 do not get in the way.

Ａピラーガーニッシュ３０の台座部３２は、ガーニッシュ本体３１と一体に成形されている。台座部３２は、クリップ挿通孔３７を有する頂壁３３と、該頂壁３３とガーニッシュ本体３１とを連結する互いに対向する一対の対向側壁３４とを有している。
台座部３２の頂壁３３と一対の対向側壁３４とガーニッシュ本体３１とで囲まれた空間部は、テザークリップ２０の一部を収容する収容空間部３８を形成している。 The pedestal 32 of the A pillar garnish 30 is formed integrally with the garnish main body 31. The pedestal portion 32 has a top wall 33 having a clip insertion hole 37 and a pair of opposed side walls 34 that connect the top wall 33 and the garnish body 31 to each other.
A space portion surrounded by the top wall 33 of the pedestal portion 32, the pair of opposing side walls 34, and the garnish main body 31 forms an accommodation space portion 38 that accommodates a part of the tether clip 20.

台座部３２の一対の対向側壁３４は、頂壁３３とガーニッシュ本体３１とを連結する方向の中間部に、収容空間部３８内に突出し対向側壁３４の間隔を狭くするくびれ部６０を有している。対向側壁３４のくびれ部６０の外面（収容空間部３８に面する面と反対側の面）は、収容空間部３８側に凹む凹部６３となっている。くびれ部６０は、Ａピラー長手方向に、ＣＳＡ１３と平行に、側壁３４全長にわたって延びている。台座部３２の対向側壁３４は、くびれ部６０を除いて、台座部３２の頂壁３３に直交しており、互いにほぼ平行である。 The pair of opposed side walls 34 of the pedestal portion 32 has a constricted portion 60 that protrudes into the accommodation space 38 and narrows the interval between the opposed side walls 34 at the intermediate portion in the direction connecting the top wall 33 and the garnish main body 31. Yes. An outer surface of the constricted portion 60 of the opposing side wall 34 (a surface opposite to the surface facing the accommodation space 38) is a recess 63 that is recessed toward the accommodation space 38. The constricted portion 60 extends over the entire length of the side wall 34 in parallel with the CSA 13 in the longitudinal direction of the A pillar. The opposing side walls 34 of the pedestal portion 32 are perpendicular to the top wall 33 of the pedestal portion 32 except for the constricted portion 60, and are substantially parallel to each other.

くびれ部６０の外面の凹部６３の形状は、部分円筒面状６１（図１、図９の実施例）または台形状６２（図１０に示す変形例）である。
部分円筒面状６１はＣＳＡ１３がロール折りの場合に用いられ、台形状６２はＣＳＡ１３がロール折りの場合にも蛇腹折りの場合にも用いられる。 The shape of the concave portion 63 on the outer surface of the constricted portion 60 is a partial cylindrical surface shape 61 (the embodiment shown in FIGS. 1 and 9) or a trapezoidal shape 62 (the modification shown in FIG. 10).
The partial cylindrical surface 61 is used when the CSA 13 is roll-folded, and the trapezoidal shape 62 is used when the CSA 13 is roll-folded or bellows-folded.

凹部６３の形状が部分円筒面状６１である場合、凹部６３の部分円筒面の径は、ロール折りのＣＳＡ１３の断面の径以上であることが望ましい。凹部６３の部分円筒面の径が、ロール折りのＣＳＡ１３の断面の径以上である場合、ＣＳＡ１３の凹部６３対向部分を凹部６３内に進入させてＣＳＡ１３の外面を凹部６３の最も深い部位の表面に接触させることができる。ＣＳＡ１３の外面を凹部６３の最も深い部位の表面に接触させた時の、ＣＳＡ１３の凹部６３への進入量Ｅは、凹部６３の最も深い部位の深さと等しい。 When the shape of the recessed part 63 is the partial cylindrical surface shape 61, it is desirable that the diameter of the partial cylindrical surface of the recessed part 63 is equal to or larger than the diameter of the cross section of the roll-folded CSA 13. When the diameter of the partial cylindrical surface of the concave portion 63 is equal to or larger than the diameter of the cross-section of the roll-folded CSA 13, the portion facing the concave portion 63 of the CSA 13 is caused to enter the concave portion 63 and the outer surface of the CSA 13 is brought into the surface of the deepest portion of the concave portion 63. Can be contacted. When the outer surface of the CSA 13 is brought into contact with the surface of the deepest portion of the recess 63, the amount of entry E of the CSA 13 into the recess 63 is equal to the depth of the deepest portion of the recess 63.

凹部６３の形状が台形状６２である場合、凹部６３の台形形状は、凹部６３の深さが深い部位（凹部６３の底部位）で対向斜辺の間隔が狭くなる形状である。また、ＣＳＡ１３が蛇腹折りの場合、凹部６３の底部位における対向斜辺の間隔（凹部６３の底の長さ）は、蛇腹折りの矩形の、凹部６３の底への対向辺の長さ以上である。凹部６３の底の長さが蛇腹折りの矩形の、凹部６３の底への対向辺の長さより長い場合、ＣＳＡ１３の一部を凹部に進入させた時に、蛇腹折りの矩形の、凹部６３の底への対向辺を、凹部６３の底に接触させることができる。この時の、ＣＳＡ１３の凹部６３への進入量Ｅは、凹部６３の底部での深さと等しい。 When the shape of the concave portion 63 is the trapezoidal shape 62, the trapezoidal shape of the concave portion 63 is a shape in which the distance between the opposing oblique sides is narrow at a portion where the depth of the concave portion 63 is deep (the bottom portion of the concave portion 63). When the CSA 13 is accordion-folded, the distance between the opposite oblique sides at the bottom portion of the recess 63 (the length of the bottom of the recess 63) is equal to or longer than the length of the opposite side of the bellows-folded rectangle to the bottom of the recess 63. . When the length of the bottom of the recess 63 is longer than the length of the opposite side to the bottom of the recess 63 when the length of the bottom of the recess 63 is a part of the CSA 13 entering the recess, The opposite side to can be brought into contact with the bottom of the recess 63. At this time, the amount of entry E of the CSA 13 into the recess 63 is equal to the depth at the bottom of the recess 63.

ＣＳＡ１３は台座部３２側に寄せられ、ＣＳＡ１３の断面の一部は、台座部３２の対向側壁３４のうちＣＳＡ１３に近い方の側壁３４の外面の凹部６３内に進入し、凹部６３の表面に近接または接触している。ＣＳＡ１３の断面の一部が凹部６３内に進入することによって、台座部３２のくびれ部６０以外での対向側壁外面間の幅ＤとＣＳＡ１３の幅Ｃ（ＣＳＡ１３がロール折りの場合はＣＳＡ１３の直径）との和が進入量Ｅ分縮小され、それにつれて運転者から見た方向Ｂの（台座部３２とＣＳＡ１３との和の）幅Ｗも縮小される。その結果、台座部３２の対向側壁間方向と平行な方向におけるＡピラー１１の幅も、縮小され、それにつれて運転者から見た方向ＢのＡピラー１１の幅も縮小される。 The CSA 13 is brought close to the pedestal 32, and a part of the cross section of the CSA 13 enters the recess 63 on the outer surface of the side wall 34 closer to the CSA 13 among the opposing side walls 34 of the pedestal 32, and is close to the surface of the recess 63. Or touch. When a part of the cross section of the CSA 13 enters the recess 63, the width D between the outer surfaces of the opposite side walls other than the constricted portion 60 of the pedestal portion 32 and the width C of the CSA 13 (the diameter of the CSA 13 when the CSA 13 is roll-folded) And the width W (the sum of the pedestal 32 and the CSA 13) in the direction B viewed from the driver is also reduced. As a result, the width of the A pillar 11 in the direction parallel to the direction between the opposing side walls of the pedestal portion 32 is also reduced, and the width of the A pillar 11 in the direction B as viewed from the driver is accordingly reduced.

ＣＳＡ１３の場合と同様に、台座部３２を挟んでＣＳＡ１３と反対側にある部品（ドレンホース４５、アンテナ４６、ワイヤハーネス４７、ウォッシャホース４８）のうち、台座部３２の側壁（部品４５〜４８に近い側の側壁）３４の凹部６３の側方に位置する部品（たとえば、アンテナ４６、ウォッシャホース４８）の断面の一部も、側壁３４の外面の凹部６３内に進入して、凹部６３の底面に近接または接触するようにしてもよい（図９の（イ）に示す）。この場合も、運転者から見た方向ＢのＡピラー１１の幅も縮小される。 As in the case of CSA 13, among the parts (drain hose 45, antenna 46, wire harness 47, washer hose 48) on the opposite side of CSA 13 across pedestal part 32, the side wall (parts 45 to 48 are attached to parts 45 to 48). A part of the cross section of a part (for example, the antenna 46 and the washer hose 48) located on the side of the recess 63 of the near side wall 34 also enters the recess 63 on the outer surface of the side wall 34, and the bottom surface of the recess 63 May be close to or in contact with each other (shown in FIG. 9A). Also in this case, the width of the A pillar 11 in the direction B as viewed from the driver is also reduced.

台座部３２の一対の対向側壁３４は、くびれ部６０を除いて、台座部３２の頂壁３３に直交している。一対の対向側壁３４は、くびれ部６０を除いて、互いに平行である。従来は一対の側壁の一方が他方に対して斜めに延びていたが、本発明では、一対の対向側壁３４は、平行に延びる。一対の対向側壁３４は、Ａピラー１１の長手方向に延びている。 The pair of opposed side walls 34 of the pedestal portion 32 are orthogonal to the top wall 33 of the pedestal portion 32 except for the constricted portion 60. The pair of opposing side walls 34 are parallel to each other except for the constricted portion 60. Conventionally, one of the pair of side walls extends obliquely with respect to the other, but in the present invention, the pair of opposing side walls 34 extend in parallel. The pair of opposed side walls 34 extends in the longitudinal direction of the A pillar 11.

台座部３３の収容空間部３８は、ガーニッシュ本体３１の長手方向に収容空間部３８の少なくとも一端（斜め上方側の一端）で開口（３６が開口を示す）している。ガーニッシュ本体３１の長手方向に見て収容空間部３８の他端は、図８に示すように、一対の対向側壁３４と直交する直交側壁３５で閉塞されていてもよいし、あるいは、開口していてもよい。 The accommodation space 38 of the pedestal 33 is opened at at least one end (one end on the oblique upper side) of the accommodation space 38 in the longitudinal direction of the garnish body 31 (36 indicates an opening). As shown in FIG. 8, the other end of the accommodation space 38 as viewed in the longitudinal direction of the garnish main body 31 may be closed by an orthogonal side wall 35 orthogonal to the pair of opposing side walls 34 or open. May be.

テザークリップ２０は、パネル部材４０への装着部であるボデー装着部２１と、フランジ部２５と、Ａピラーガーニッシュ３０への装着部であるガーニッシュ装着部２２と、テザークリップ先端部に形成されたアンカー部２４と、ガーニッシュ装着部２２とアンカー部２４との間にわたって延びる可撓性のテザー部２３とを有している。ボデー装着部２１はフランジ部２５に対して収容空間部３８と反対側にあり、ガーニッシュ装着部２２と、テザー部２３と、アンカー部２４とは、フランジ部２５に対して収容空間部３８側にある。
テザークリップ２０のテザー部２３とアンカー部２４とは、少なくとも一部が収容空間部３８内に収容されている。
アンカー部２４は、中央に、台座部頂壁のクリップ挿通孔縁部に当たった時の衝撃を緩和する切り込み２４ａを有し、この切り込み２４ａを中心にして左右対称形である。 The tether clip 20 includes a body mounting portion 21 that is a mounting portion to the panel member 40, a flange portion 25, a garnish mounting portion 22 that is a mounting portion to the A-pillar garnish 30, and an anchor formed at the tip of the tether clip. And a flexible tether portion 23 extending between the garnish mounting portion 22 and the anchor portion 24. The body mounting portion 21 is on the opposite side of the housing space portion 38 with respect to the flange portion 25, and the garnish mounting portion 22, the tether portion 23, and the anchor portion 24 are on the housing space portion 38 side with respect to the flange portion 25. is there.
At least a part of the tether portion 23 and the anchor portion 24 of the tether clip 20 is accommodated in the accommodating space portion 38.
The anchor portion 24 has a notch 24a at the center for relaxing the impact when hitting the edge of the clip insertion hole on the top wall of the pedestal portion, and is symmetrical with respect to the notch 24a.

ボデー装着部２１の爪部２１ａは、ボデー装着部２１をインナーパネル４１の孔に挿入する時には対向爪部間隔が縮小して挿入可能とし、挿入後は自身の弾性で元の位置に復帰して、ボデー装着部２１がインナーパネル４１から抜けないようにする。同様に、ガーニッシュ装着部２２の爪部２２ａは、ガーニッシュ装着部２２を台座部３２の頂壁３３のクリップ挿通孔３７にアンカー部２４およびテザー部２３側から装着する時には対向爪部間隔が縮小して挿入可能とし、挿入後は自身の弾性で元の位置に復帰して、ガーニッシュ装着部２２が台座部３２の頂壁３３から抜けないようにする。 When inserting the body mounting portion 21 into the hole of the inner panel 41, the claw portion 21a of the body mounting portion 21 can be inserted with the interval between the opposing claw portions reduced, and after insertion, the claw portion 21a returns to its original position by its own elasticity. The body mounting portion 21 is prevented from being detached from the inner panel 41. Similarly, the claw portion 22a of the garnish mounting portion 22 reduces the distance between the opposing claw portions when the garnish mounting portion 22 is mounted to the clip insertion hole 37 of the top wall 33 of the pedestal portion 32 from the anchor portion 24 and the tether portion 23 side. After insertion, the garnish mounting portion 22 is restored to its original position by its own elasticity so that the garnish mounting portion 22 does not come off from the top wall 33 of the pedestal portion 32.

テザークリップ２０のテザー部２３は、図６に示すように、単品状態で（台座部３２に取り付けられる前の状態）曲がっている。
また、Ａピラーガーニッシュ３０のＡピラーパネル部材４０への取付け完了状態で、テザークリップ２０のテザー部２３は、単品状態での曲がりを維持しており、テザー部２３の曲がり方向をＡピラー１１の長手方向に向けられている。従来では、テザー部はＡピラーの長手方向と直交する方向に曲がっているが、本発明では、テザー部２３はＡピラー１１の長手方向に曲がっている。 As shown in FIG. 6, the tether portion 23 of the tether clip 20 is bent in a single product state (a state before being attached to the pedestal portion 32).
In addition, when the A pillar garnish 30 is completely attached to the A pillar panel member 40, the tether portion 23 of the tether clip 20 maintains the bending in a single product state, and the bending direction of the tether portion 23 is set to the bending direction of the A pillar 11. Oriented in the longitudinal direction. Conventionally, the tether portion is bent in a direction orthogonal to the longitudinal direction of the A pillar, but in the present invention, the tether portion 23 is bent in the longitudinal direction of the A pillar 11.

テザー部２３は、収容空間部３８内で、Ａピラー長手方向に、台座部３２の開口３６側に、曲がっている。
テザークリップ２０の先端部（アンカー部２４側の先端部）は、図８に示すように、台座部３３の収容空間部３８の一端の開口３６から、収容空間部３８外に突出している。 The tether portion 23 is bent toward the opening 36 of the pedestal portion 32 in the A-pillar longitudinal direction within the accommodation space portion 38.
As shown in FIG. 8, the distal end portion of the tether clip 20 (the distal end portion on the anchor portion 24 side) protrudes outside the accommodation space portion 38 from the opening 36 at one end of the accommodation space portion 38 of the pedestal portion 33.

図６、図７に示すように、テザー部２３は、テザー部２３の少なくとも根元部（ガーニッシュ装着部２２側の端部）において、矩形状の横断面を有する。テザー部２３は、テザー部２３の根元部における、横断面の矩形の短辺方向（短辺が延びる方向）がガーニッシュ本体３１の長手方向（Ａピラー１１の長手方向）に向けられている。 As shown in FIGS. 6 and 7, the tether portion 23 has a rectangular cross section at least at the root portion (the end portion on the garnish mounting portion 22 side) of the tether portion 23. In the tether portion 23, the short side direction (the direction in which the short side extends) of the rectangular cross section at the base portion of the tether portion 23 is directed to the longitudinal direction of the garnish main body 31 (longitudinal direction of the A pillar 11).

上記のＡピラーガーニッシュ取付け装置１０において、台座部３２の頂壁３３に設けられたクリップ挿通孔３７は矩形状である。
台座部頂壁３３のクリップ挿通孔３７は、クリップ挿通孔３７の矩形の長手方向をガーニッシュ本体３１の長手方向（Ａピラー１１の長手方向）に向けられている。 In the A pillar garnish attaching device 10 described above, the clip insertion hole 37 provided in the top wall 33 of the pedestal portion 32 has a rectangular shape.
The clip insertion hole 37 of the pedestal portion top wall 33 has the rectangular longitudinal direction of the clip insertion hole 37 oriented in the longitudinal direction of the garnish body 31 (longitudinal direction of the A pillar 11).

また、テザークリップ２０のアンカー部２４は矩形状の外形を有する。
テザークリップ２０のアンカー部２４は、テザークリップ２０をＡピラーガーニッシュ３０に装着した状態で、アンカー部２４の矩形状の外形の長手方向がガーニッシュ本体３１の長手方向（Ａピラー１１の長手方向）と直交する方向に向けられている。 The anchor portion 24 of the tether clip 20 has a rectangular outer shape.
In the anchor portion 24 of the tether clip 20, the longitudinal direction of the rectangular outer shape of the anchor portion 24 is the longitudinal direction of the garnish body 31 (longitudinal direction of the A pillar 11) in a state where the tether clip 20 is attached to the A pillar garnish 30. It is oriented in the orthogonal direction.

矩形状外形を有するアンカー部２４の長手方向の長さは、台座部３２の頂壁３３に形成された矩形状外形を有するクリップ挿通孔３７の長手方向と直交する方向の長さより長い。
また、アンカー部２４の矩形状外形の大きさは、台座部３２の頂壁３３に形成された、矩形状クリップ挿通孔３７の大きさより小さい。
テザー部２３の矩形状横断面の大きさは、アンカー部２４の矩形状外形の大きさより小さい。
テザー部２３の矩形状横断面の長辺の長さは、台座部３２の頂壁３３に形成された、矩形状クリップ挿通孔３７の短辺の長さより短い。
テザークリップ２０のガーニッシュ装着部２２は、矩形状の外形を有し、爪部２２ａを除き、台座部３２の頂壁３３に形成された矩形状のクリップ挿通孔３７より若干小さい外形を有する。爪部２２ａを入れたガーニッシュ装着部２２の外形は、クリップ挿通孔３７より大きい。 The length in the longitudinal direction of the anchor portion 24 having the rectangular outer shape is longer than the length in the direction orthogonal to the longitudinal direction of the clip insertion hole 37 having the rectangular outer shape formed in the top wall 33 of the pedestal portion 32.
The size of the rectangular outer shape of the anchor portion 24 is smaller than the size of the rectangular clip insertion hole 37 formed in the top wall 33 of the pedestal portion 32.
The size of the rectangular cross section of the tether portion 23 is smaller than the size of the rectangular outer shape of the anchor portion 24.
The length of the long side of the rectangular cross section of the tether portion 23 is shorter than the length of the short side of the rectangular clip insertion hole 37 formed in the top wall 33 of the pedestal portion 32.
The garnish mounting portion 22 of the tether clip 20 has a rectangular outer shape, and has an outer shape slightly smaller than the rectangular clip insertion hole 37 formed in the top wall 33 of the pedestal portion 32 except for the claw portion 22a. The outer shape of the garnish mounting portion 22 including the claw portion 22 a is larger than the clip insertion hole 37.

台座部３２の対向側壁３４のくびれ部６０は、収容空間部３８内に突出する、１つ以上のリブ６４を有する。リブ６４は、くびれ部６０の収容空間部３８内への凸形状の頂点よりも収容空間部３８内に突出している。リブ６４は、くびれ部６０の収容空間部３８に面する内面の、Ａピラー長手方向における、全長かまたはほぼ全長にわたって形成されている。 The constricted portion 60 of the opposing side wall 34 of the pedestal portion 32 has one or more ribs 64 protruding into the accommodation space portion 38. The rib 64 protrudes into the housing space 38 from the convex apex of the constricted portion 60 into the housing space 38. The rib 64 is formed over the entire length or almost the entire length in the A-pillar longitudinal direction of the inner surface of the constricted portion 60 facing the accommodation space 38.

台座部３２の対向側壁３４のくびれ部６０に設けられたリブ６４の間隔（対向側壁３４の一方の側壁のリブ６４と他方の側壁のリブ６４との間隔）Ｄ１は、アンカー部２４の外形の矩形の長手方向の寸法Ｄ２以下である。
台座部３２の対向側壁３４のくびれ部６０の内面間の間隔（対向側壁３４の一方の側壁のくびれ部６０の内面と他方の側壁のくびれ部６０の内面との間隔）Ｄ３は、アンカー部２４の外形の矩形の長手方向の寸法Ｄ２以上である。
これによって、ＣＳＡ１３の展開時に、アンカー部２４はくびれ部６０を通過できるが、アンカー部２４がリブ６４に摺動接触し、摩擦を生じてエネルギーが吸収されるようになる。 The interval between ribs 64 provided on the constricted portion 60 of the opposing side wall 34 of the pedestal portion 32 (the interval between the rib 64 on one side wall of the opposing side wall 34 and the rib 64 on the other side wall) D1 is the outer shape of the anchor portion 24. It is below the dimension D2 of the rectangular longitudinal direction.
The distance between the inner surfaces of the constricted portion 60 of the opposed side wall 34 of the pedestal portion 32 (the distance between the inner surface of the constricted portion 60 of one side wall of the opposed side wall 34 and the inner surface of the constricted portion 60 of the other side wall) D3 is It is the dimension D2 or more in the longitudinal direction of the rectangle of the outer shape.
As a result, when the CSA 13 is deployed, the anchor portion 24 can pass through the constricted portion 60, but the anchor portion 24 comes into sliding contact with the rib 64, and friction is generated to absorb energy.

Ａピラーガーニッシュ３０のパネル部材４０への取付け手順はつぎのとおりである。
畳まれた状態のＣＳＡ１３が図示略のＣＳＡ固定クリップによってＡピラー１１のインナーパネル４１に取付けられる。部品４５〜４８も配置される。
テザークリップ２０がＡピラーガーニッシュ３０の台座部３２に取り付けられる。その後、テザークリップ２０のボデー装着部２１がインナーパネル４１の孔に挿入され、Ａピラーガーニッシュ３０がインナーパネル４１に取付けられる。この時、ＣＳＡ１３の断面の一部が、Ａピラーガーニッシュ３０の台座部３２のくびれ部６０外面の凹部６３に進入するようにする。Ａピラーガーニッシュ３０は、ＣＳＡ１３および部品４５〜４８を車室側から覆う。 The procedure for attaching the A pillar garnish 30 to the panel member 40 is as follows.
The folded CSA 13 is attached to the inner panel 41 of the A pillar 11 by a CSA fixing clip (not shown). Parts 45-48 are also arranged.
The tether clip 20 is attached to the pedestal 32 of the A pillar garnish 30. Thereafter, the body mounting portion 21 of the tether clip 20 is inserted into the hole of the inner panel 41, and the A pillar garnish 30 is attached to the inner panel 41. At this time, a part of the cross section of the CSA 13 enters the concave portion 63 on the outer surface of the constricted portion 60 of the base portion 32 of the A pillar garnish 30. The A pillar garnish 30 covers the CSA 13 and the parts 45 to 48 from the passenger compartment side.

テザークリップ２０の、Ａピラーガーニッシュ３０の台座部３２への取付けにおいては、テザークリップ２０を、アンカー部２４側から台座部３２の頂壁３３のクリップ挿通孔３７を挿通させてアンカー部２４を収容空間部３８内に挿入する。この時、アンカー部２４の矩形状外形の長手方向と、クリップ挿通孔３７の矩形の長手方向とを合わせる。テザー部２３の曲がりの方向は、ガーニッシュ本体３１の長手方向と直交する方向に向けられている。アンカー部２４の外形の矩形の大きさは、台座部３２の頂壁３３のクリップ挿通孔３７の矩形の大きさより小さいため、アンカー部２４はクリップ挿通孔３７を通り抜ける。アンカー部２４がクリップ挿通孔３７およびくびれ部６０を挿通したところで、テザークリップ２０を９０度回転させ、テザー部２３の曲がりの方向が、ガーニッシュ本体３１の長手方向に向くようにする。 In attaching the tether clip 20 to the pedestal portion 32 of the A pillar garnish 30, the anchor portion 24 is accommodated by inserting the tether clip 20 from the anchor portion 24 side through the clip insertion hole 37 of the top wall 33 of the pedestal portion 32. Insert into the space 38. At this time, the longitudinal direction of the rectangular outer shape of the anchor portion 24 is aligned with the longitudinal direction of the rectangle of the clip insertion hole 37. The bending direction of the tether portion 23 is directed in a direction orthogonal to the longitudinal direction of the garnish body 31. Since the rectangular size of the outer shape of the anchor portion 24 is smaller than the rectangular size of the clip insertion hole 37 of the top wall 33 of the pedestal portion 32, the anchor portion 24 passes through the clip insertion hole 37. When the anchor portion 24 has passed through the clip insertion hole 37 and the constricted portion 60, the tether clip 20 is rotated 90 degrees so that the bending direction of the tether portion 23 faces the longitudinal direction of the garnish main body 31.

さらに、テザー部２３をクリップ挿通孔３７に挿通させていき、テザー部２３を収容空間部３８に入れる。テザー部２３の矩形状横断面の長辺の長さは、台座部３２の頂壁３３の矩形状クリップ挿通孔３７の短辺の長さより短いため、テザー部２３はクリップ挿通孔３７を挿通する。この時、テザー部２３の曲がりの方向は、ガーニッシュ本体３１の長手方向に向けられている。 Further, the tether portion 23 is inserted through the clip insertion hole 37, and the tether portion 23 is inserted into the accommodation space portion 38. Since the length of the long side of the rectangular cross section of the tether portion 23 is shorter than the length of the short side of the rectangular clip insertion hole 37 of the top wall 33 of the pedestal portion 32, the tether portion 23 passes through the clip insertion hole 37. . At this time, the bending direction of the tether portion 23 is directed to the longitudinal direction of the garnish main body 31.

ついで、テザークリップ２０のガーニッシュ装着部２２が台座部３２の頂壁３３のクリップ挿通孔３７に押し込まれ挿通される。ガーニッシュ装着部２２の爪部２２ａがクリップ挿通孔３７を挿通すると、爪部２２ａが弾性復帰し、テザークリップ２０が台座部３２から抜け落ちないようになる。この状態では、テザークリップ２０のフランジ部２５が台座部３２の頂壁３３に接触する。また、テザー部２３の曲がりの方向は、ガーニッシュ本体３１の長手方向に向けられている。 Subsequently, the garnish mounting portion 22 of the tether clip 20 is pushed into and inserted into the clip insertion hole 37 of the top wall 33 of the pedestal portion 32. When the claw portion 22a of the garnish mounting portion 22 is inserted through the clip insertion hole 37, the claw portion 22a is elastically restored, and the tether clip 20 is prevented from falling off the pedestal portion 32. In this state, the flange portion 25 of the tether clip 20 contacts the top wall 33 of the pedestal portion 32. Further, the bending direction of the tether portion 23 is directed to the longitudinal direction of the garnish body 31.

その後、テザークリップ２０が装着されているＡピラーガーニッシュ３０をパネル部材４０に取付ける。この取付けにおいては、テザークリップ２０のボデー装着部２１を、Ａピラーのインナーパネル４１のテザークリップ取付け孔に押し込む。ボデー装着部２１の爪部２１ａがテザークリップ取付け孔を通り抜けると、爪部２１ａが元の位置に弾性復帰し、テザークリップ２０がインナーパネル４１から外れなくなる。この状態では、テザー部２３の曲がりの方向は、ガーニッシュ本体３１の長手方向、すなわち、Ａピラーの長手方向に向けられている。 Thereafter, the A pillar garnish 30 to which the tether clip 20 is attached is attached to the panel member 40. In this attachment, the body mounting portion 21 of the tether clip 20 is pushed into the tether clip attachment hole of the inner panel 41 of the A pillar. When the claw portion 21a of the body mounting portion 21 passes through the tether clip mounting hole, the claw portion 21a elastically returns to the original position, and the tether clip 20 cannot be detached from the inner panel 41. In this state, the bending direction of the tether portion 23 is directed to the longitudinal direction of the garnish body 31, that is, the longitudinal direction of the A pillar.

つぎに、Ａピラーガーニッシュ取付け装置１０の、ＣＳＡ１３の展開、膨張時の作動を説明する。
衝突検知センサまたは衝突予知センサが車両の衝突を検知または予知すると、ＥＣＵがインフレータを作動させ、インフレータからの膨張用ガスがＣＳＡ１３に供給される。それまで畳まれていたＣＳＡ１３が、図１１において、Ａピラー１１では、２点鎖線１３’で示すように、展開、膨張していく。 Next, the operation of the A pillar garnish attaching device 10 when the CSA 13 is expanded and expanded will be described.
When the collision detection sensor or the collision prediction sensor detects or predicts the collision of the vehicle, the ECU activates the inflator and the inflation gas from the inflator is supplied to the CSA 13. The CSA 13 that has been folded until then is expanded and expanded in the A pillar 11 as shown by a two-dot chain line 13 'in FIG.

Ａピラー１１においては、図１に示すように、展開膨張するＣＳＡ１３から力を受けて、Ａピラーガーニッシュ３０が押し拡げられる。図１で２点差線３０’は押し広げられる途中のＡピラーガーニッシュを示す。Ａピラーガーニッシュ３０が押し拡げられる時、台座部３２の頂壁３３がインナーパネル４１から離れていき、頂壁３３のクリップ挿通孔３７周縁部がガーニッシュ装着部２２の爪部２２ａを押して弾性変形させ、ガーニッシュ装着部２２を通過する。頂壁３３のクリップ挿通孔３７周縁部は、さらにテザー部２３と摺動しつつ移動し、テザー部２３をそれまで曲がっていた状態から真直の状態に弾性変形させ、アンカー部２４に向かって移動する。 In the A pillar 11, as shown in FIG. 1, the A pillar garnish 30 is pushed and expanded by receiving a force from the expanding and expanding CSA 13. In FIG. 1, a two-point difference line 30 ′ indicates an A-pillar garnish that is being expanded. When the A pillar garnish 30 is expanded, the top wall 33 of the pedestal portion 32 moves away from the inner panel 41, and the peripheral edge of the clip insertion hole 37 of the top wall 33 pushes the claw portion 22a of the garnish mounting portion 22 to be elastically deformed. , Passing through the garnish mounting part 22. The peripheral edge of the clip insertion hole 37 of the top wall 33 further moves while sliding with the tether portion 23, elastically deforms the tether portion 23 from the bent state until then, and moves toward the anchor portion 24. To do.

逆に、アンカー部２４から見れば、アンカー部２４は、図９の（イ）の状態から、台座部３２に対して頂壁３３に向かって相対移動を始め、途中で図９の（ロ）の状態になって、くびれ部６０を通過する。その時、アンカー部材２４とリブ６４とが摺動接触し、摩擦によりエネルギーが吸収され、アンカー部２４が頂壁３３向かって相対移動する速度が低減される。
そして、ついにアンカー部２４と頂壁３３のクリップ挿通孔３７周縁部とが当たった位置で、台座部３２の頂壁３３がインナーパネル４１から離れていく動きが止まり、Ａピラーガーニッシュ３０が乗員へ向かって飛散することが防止される。アンカー部２４とリブ６４と摺動接触によるエネルギー吸収により、アンカー部２４と頂壁３３のクリップ挿通孔３７周縁部との当たりが弱まり、テザークリップのテザー部２３の破断がより確実に防止される。 Conversely, when viewed from the anchor part 24, the anchor part 24 starts to move relative to the top wall 33 with respect to the pedestal part 32 from the state of FIG. And passes through the constricted portion 60. At that time, the anchor member 24 and the rib 64 come into sliding contact, energy is absorbed by friction, and the speed at which the anchor portion 24 moves relative to the top wall 33 is reduced.
Finally, at the position where the anchor portion 24 and the peripheral edge of the clip insertion hole 37 of the top wall 33 contact each other, the movement of the top wall 33 of the pedestal portion 32 away from the inner panel 41 stops, and the A pillar garnish 30 is directed to the occupant. It is prevented from scattering toward. Due to energy absorption by sliding contact between the anchor portion 24 and the rib 64, the contact between the anchor portion 24 and the peripheral portion of the clip insertion hole 37 of the top wall 33 is weakened, and breakage of the tether portion 23 of the tether clip is more reliably prevented. .

Ａピラーガーニッシュ３０が押し拡げられることにより、Ａピラーガーニッシュ３０とＡピラーのインナーパネル４１との間に、台座部３２より車室内側に、ＣＳＡ展開用間隔が形成される。テザー部２３が曲がっていた状態から真直の状態に変形されるので、台座部３２の頂壁３３がインナーパネル４１から離れる時の移動距離が長くとれ、ＣＳＡ展開用間隔を十分に大きくすることができる。このＣＳＡ展開用間隔を通して、ＣＳＡ１３が、車室内に、かつ乗員とサイドウインドとの間の空間に、展開膨張され、乗員頭部を側突から保護する。 When the A pillar garnish 30 is expanded, a CSA deployment interval is formed between the A pillar garnish 30 and the inner panel 41 of the A pillar on the vehicle interior side from the pedestal portion 32. Since the tether portion 23 is deformed from a bent state to a straight state, the moving distance when the top wall 33 of the pedestal portion 32 moves away from the inner panel 41 can be increased, and the CSA deployment interval can be sufficiently increased. it can. Through this CSA deployment interval, the CSA 13 is deployed and inflated in the vehicle interior and in the space between the occupant and the side window to protect the occupant head from side collision.

つぎに、本発明のＡピラーガーニッシュ取付け装置１０の効果を説明する。
台座部３２の対向側壁３４がくびれ部６０を有しているので、対向側壁３４の外側面がくびれ部６０において収容空間部３８側に凹んだ凹部６３を形成している。この凹部６３に、Ａピラーガーニッシュ裏側に配置される部品（たとえば、ＣＳＡ１３）の一部を進入させ、該部品を、対向側壁３４の凹部６３の表面に寄せて配置することができるので、Ａピラー１１が細幅化される。 Next, the effect of the A pillar garnish attaching device 10 of the present invention will be described.
Since the opposed side wall 34 of the pedestal 32 has the constricted portion 60, the outer surface of the opposed side wall 34 forms a concave portion 63 that is recessed toward the accommodation space 38 in the constricted portion 60. A part of a part (for example, CSA 13) arranged on the back side of the A pillar garnish is made to enter the concave part 63, and the part can be arranged close to the surface of the concave part 63 of the opposing side wall 34. 11 is narrowed.

たとえば、ＣＳＡ１３の一部（凹部６３に対向するＣＳＡ部分）が凹部６３に進入するようにＣＳＡ１３を台座部３２に寄せて配置することにより、くびれ部６０以外の部位での台座部３２の幅ＤとＣＳＡ１３の断面の幅Ｃの和の幅（Ｄ＋Ｃ）が、従来（台座部側壁にくびれ部が形成されない場合）に比べて、ＣＳＡ１３の一部の凹部６３への進入量Ｅ分、狭くなる。その結果、運転者から見た方向Ｂの台座部３２とＣＳＡ１３の和の幅Ｗが従来（台座部側壁にくびれ部が形成されない場合）の運転者から見た方向Ｂの台座部とＣＳＡの和のＷｐに比べて狭くなる。それにつれて、運転者から見た方向ＢのＡピラー１１の幅も、従来装置に比べ、狭くなる。その結果、視界がＡピラー１１によって遮られにくくなり、視界が改善される。
図１は、助手席側のＡピラー１１を示しているが、運転席側もこれに準じた、Ａピラー１１の狭幅化効果がある。 For example, by placing the CSA 13 close to the pedestal portion 32 so that a part of the CSA 13 (the CSA portion facing the recessed portion 63) enters the recessed portion 63, the width D of the pedestal portion 32 at a portion other than the constricted portion 60. The width (D + C) of the cross-sectional width C of the CSA 13 becomes narrower by the amount of entry E into the concave portion 63 of a part of the CSA 13 than in the conventional case (when the constricted portion is not formed on the side wall of the pedestal portion). As a result, the width W of the sum of the pedestal portion 32 and the CSA 13 in the direction B as viewed from the driver is the sum of the pedestal portion in the direction B and the sum of the CSA as viewed from the driver (when the constricted portion is not formed on the side wall of the pedestal portion). Narrower than Wp. Accordingly, the width of the A pillar 11 in the direction B as viewed from the driver is also narrower than that of the conventional device. As a result, the field of view is not easily blocked by the A pillar 11, and the field of view is improved.
FIG. 1 shows the A pillar 11 on the passenger seat side, but the driver seat side also has an effect of narrowing the A pillar 11 in accordance with this.

テザー部２３がテザークリップ２０の単品状態ですでに曲がっており（従来のように、組み付け時にガイドで曲げるものではない）、かつ、テザー部２３の曲がり方向がＡピラー１１の長手方向に向けられている（従来は、Ａピラー１１の長手方向と直交方向に曲げられていた）。そのため、テザー部の曲がり方向がＡピラーの長手方向と直交する方向であった従来装置に比べ、台座部３２の幅Ｄ（Ａピラー１１の長手方向と直交する方向の台座部３２の寸法）を狭くすることができる。従来はテザー部の曲がりを収容できるように台座部８の幅Ｄｐが広くされていた。 The tether portion 23 is already bent in a single product state of the tether clip 20 (as in the conventional case, it is not bent by a guide during assembly), and the bending direction of the tether portion 23 is directed to the longitudinal direction of the A pillar 11. (Conventionally, it is bent in the direction perpendicular to the longitudinal direction of the A pillar 11). Therefore, the width D of the pedestal portion 32 (the dimension of the pedestal portion 32 in the direction orthogonal to the longitudinal direction of the A pillar 11) is compared with the conventional device in which the bending direction of the tether portion is the direction orthogonal to the longitudinal direction of the A pillar. It can be narrowed. Conventionally, the width Dp of the pedestal portion 8 has been widened to accommodate the bending of the tether portion.

また、台座部３２の幅Ｄが狭くなった分、運転者から見た方向Ｂにおける、台座部３２とＣＳＡ１３の和の幅Ｗが、従来の台座部とＣＳＡの和の幅Ｗｐ（図１２）に比べて小さくなり、運転者から見た方向ＢのＡピラー１１の幅が、従来装置に比べ、狭くなる。その結果、視界がＡピラー１１によって遮られにくくなり、視界が改善される。 Moreover, the width W of the sum of the base part 32 and the CSA 13 in the direction B as viewed from the driver is equal to the width Wp of the sum of the conventional base part and the CSA, as the width D of the base part 32 is reduced (FIG. 12). The width of the A pillar 11 in the direction B as viewed from the driver is narrower than that of the conventional device. As a result, the field of view is not easily blocked by the A pillar 11, and the field of view is improved.

台座部３２の対向側壁３４のくびれ部６０は収容空間部３８内に突出するリブ６４を有し、該対向側壁のリブ６４の間隔（対向側壁３４の、一方の側壁のリブと他方の側壁のリブとの間隔）が、テザークリップ２０のアンカー部２４の外形の矩形の長手方向の寸法以下であるので、ＣＳＡ１３の展開時に、台座部頂壁３３がアンカー部２４側に相対移動する時に、アンカー部２４が台座部３２のくびれ部６０のリブ６４と摺動接触し、その時の摩擦によるエネルギー吸収作用が得られる。これによって、台座部頂壁３３がアンカー部２４側に相対移動する速度が低減される。その結果、アンカー部２４がくびれ部６０を通り抜けて台座部頂壁３３のクリップ挿通孔３７の周縁部に衝突する時の衝突力が弱められ、テザー２３部が（とくに、低温時に）破断することが防止される。これによって、テザー部２３が破断した場合には生じるかもしれないＡピラーガーニッシュ３０の飛散が抑制される。 The constricted portion 60 of the opposing side wall 34 of the pedestal portion 32 has ribs 64 protruding into the accommodating space portion 38, and the interval between the ribs 64 of the opposing side wall (the ribs of one side wall and the other side wall of the opposing side wall 34 are Since the distance between the ribs) is equal to or less than the longitudinal dimension of the outer shape of the anchor portion 24 of the tether clip 20, when the CSA 13 is deployed, the pedestal top wall 33 moves relative to the anchor portion 24 side. The portion 24 is in sliding contact with the rib 64 of the constricted portion 60 of the pedestal portion 32, and an energy absorbing action by friction at that time is obtained. This reduces the speed at which the pedestal top wall 33 moves relative to the anchor portion 24 side. As a result, the collision force when the anchor portion 24 passes through the constricted portion 60 and collides with the peripheral portion of the clip insertion hole 37 of the base portion top wall 33 is weakened, and the tether 23 portion is broken (particularly at low temperatures). Is prevented. As a result, scattering of the A pillar garnish 30 that may occur when the tether portion 23 breaks is suppressed.

台座部３２の対向側壁３４のくびれ部６０が、部分円筒形状６１を有する場合は、くびれ部６０の外面の凹部６３の表面は部分円筒形状をなす。一方、ＣＳＡがロール折りの場合は、ＣＳＡの断面の外形がほぼ円形である。したがって、くびれ部６０の外面の部分円筒形状凹部６３は、凹部６３の部分円筒形状の径がＣＳＡ１３の円形断面の径以上である限り、ＣＳＡ１３の断面の一部を、該ＣＳＡ１３の断面が凹部６３の最も深い部位の表面に接触するように、収容可能である。ＣＳＡ１３の断面が凹部６３の最も深い部位の表面に接触する状態で、ＣＳＡ１３の断面が台座部３２に最も寄せられ、ＣＳＡ１３の凹部６３への進入量Ｅが最大で、Ａピラーを最も狭幅化することができる。 When the constricted part 60 of the opposing side wall 34 of the base part 32 has the partial cylindrical shape 61, the surface of the recessed part 63 of the outer surface of the constricted part 60 makes a partial cylindrical shape. On the other hand, when the CSA is roll-folded, the outer shape of the cross section of the CSA is substantially circular. Therefore, as long as the diameter of the partial cylindrical shape of the concave portion 63 is equal to or larger than the diameter of the circular cross section of the CSA 13, the partial cylindrical concave portion 63 on the outer surface of the constricted portion 60 is a part of the cross section of the CSA 13 and the cross section of the CSA 13 is the concave portion 63. It can be accommodated so as to be in contact with the surface of the deepest part. In a state where the cross section of the CSA 13 is in contact with the surface of the deepest part of the concave portion 63, the cross section of the CSA 13 is most brought close to the pedestal portion 32, the amount of entry E of the CSA 13 into the concave portion 63 is the largest, and the A pillar is the narrowest. can do.

台座部３２の対向側壁３４のくびれ部６０が、台形形状６２を有する場合、くびれ部６０の外面の凹部６３も台形状をなす。一方、ＣＳＡ１３が蛇腹折りの場合は、ＣＳＡの断面の外形がほぼ矩形である。したがって、くびれ部６０の外面の台形凹部６３は、凹部６３の底の長さがＣＳＡの断面矩形の凹部対向辺の長さ以上である限り、ＣＳＡ１３の断面の一部を、該ＣＳＡ１３の断面矩形の凹部対向面が凹部６３の底に接触するように、収容可能である。ＣＳＡ１３の断面が凹部６３の底に接触する状態で、ＣＳＡ１３の断面が台座部３２に最も寄せられ、ＣＳＡ１３の凹部６３への進入量Ｅが最大で、Ａピラーを最も狭幅化することができる。 When the constricted portion 60 of the opposed side wall 34 of the pedestal portion 32 has a trapezoidal shape 62, the concave portion 63 on the outer surface of the constricted portion 60 also has a trapezoidal shape. On the other hand, when the CSA 13 is accordion folded, the outer shape of the cross section of the CSA is substantially rectangular. Accordingly, the trapezoidal concave portion 63 on the outer surface of the constricted portion 60 is formed so that a part of the cross section of the CSA 13 is partly rectangular as long as the bottom length of the concave portion 63 is equal to or longer than the length of the opposite side of the concave portion of the CSA cross sectional rectangle. Can be accommodated so that the concave-facing surface thereof contacts the bottom of the concave portion 63. In a state where the cross section of the CSA 13 is in contact with the bottom of the concave portion 63, the cross section of the CSA 13 is most brought close to the pedestal portion 32, the amount of entry E of the CSA 13 into the concave portion 63 is maximum, and the A pillar can be narrowed most. .
