Description

本発明は、カーテン式エアバッグを備えた車両のピラートリム取付構造に関するものである。   The present invention relates to a pillar trim mounting structure for a vehicle having a curtain airbag.

自動車等の車両においては、側方からの衝撃に対して乗員を保護するために、ピラーインナパネルの車室側内面にカーテン式エアバッグとこれに連結されたテザーベルトを車体前後方向に沿って配設することが行われている。そして、カーテン式エアバッグとテザーベルトが配設されたピラーインナパネルにはピラートリムが車室内側から被着され、該ピラートリムは、ピラーインナパネルに形成された取付孔にクリップを介して固定されている。   In vehicles such as automobiles, curtain type airbags and tether belts connected to them are arranged along the longitudinal direction of the vehicle body on the inner surface of the pillar inner panel on the passenger compartment side to protect passengers against side impacts. It has been done. A pillar trim is attached to the pillar inner panel provided with the curtain airbag and the tether belt from the vehicle interior side, and the pillar trim is fixed to a mounting hole formed in the pillar inner panel via a clip. .

而して、車両が側方からの衝撃を受けるとカーテン式エアバッグが展開膨張し、これによってピラートリムが移動し、該ピラートリムとピラーインナパネルとの間が開いて開口部が形成され、この開口部から膨張したカーテン式エアバッグが車室内に展開して乗員を衝撃から保護する。   Thus, when the vehicle receives an impact from the side, the curtain airbag is deployed and inflated, whereby the pillar trim moves, and an opening is formed between the pillar trim and the pillar inner panel. A curtain-type airbag that is inflated from the section is deployed in the passenger compartment to protect the occupant from impact.

ところが、上述のピラートリムの移動に伴って該ピラートリムのクリップによる固定が外れると、該ピラートリムの車室内側への移動量が大きくなる恐れがある。   However, if the pillar trim is not fixed by the clip along with the movement of the pillar trim, the amount of movement of the pillar trim toward the vehicle interior may increase.

又、カーテン式エアバッグとテザーベルトが車体に先付けされている状態でピラートリムを組み付ける場合、組付部分を目視で確認しながら組み付けることが困難であるため、ピラートリム内に既に配設されているテザーベルトがピラートリムに挟み込まれたり、クリップ取付部よりも上方にテザーベルトが取り付けられる可能性があった。   Also, when the pillar trim is assembled with the curtain airbag and the tether belt attached to the vehicle body, it is difficult to assemble while visually checking the assembly portion. There is a possibility that the tether belt may be sandwiched between pillar trims or the tether belt may be attached above the clip attachment portion.

そこで、例えば特許文献１には、カーテン式エアバッグの展開時にピラートリムが外れないようにするため、ピラートリムの裏面に一体に突設された係止片をピラーインナパネルの係止孔に係止させる構成が提案されている。   Therefore, for example, in Patent Document 1, in order to prevent the pillar trim from being removed when the curtain airbag is deployed, a locking piece integrally protruding on the back surface of the pillar trim is locked in a locking hole of the pillar inner panel. A configuration is proposed.

又、特許文献２には、ピラートリムを離脱可能にピラーインナパネルに係止する係止部を設けるとともに、ピラートリムとピラーインナパネルとを結合する結合部材を設け、カーテン式エアバッグの展開に伴って係止部が外れると、結合部材の引っ張り時の制限によってピラートリムの車室内への移動を制限する構成が提案されている。
特開２００１−３１０６９９号公報 特開２００３−３３５２０５号公報 Further, in Patent Document 2, a locking portion for locking the pillar trim to the pillar inner panel so as to be detachable is provided, and a coupling member for coupling the pillar trim and the pillar inner panel is provided. A configuration has been proposed in which when the locking portion is released, the movement of the pillar trim into the vehicle interior is restricted by the restriction when the coupling member is pulled.

以下に本発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１は本発明に係るピラートリム取付構造を示す分解斜視図、図２は同断面図、図３はピラートリムの組付作業を示す断面図、図４はピラートリムが組み付けられた後にテザーベルトが補強用リブに沿って所定位置に配置された状態を示す断面図、図５はカーテン式エアバッグ展開時の状態を示す断面図、図６はカーテン式エアバッグ展開後の状態を示す断面図である。   1 is an exploded perspective view showing a pillar trim mounting structure according to the present invention, FIG. 2 is a cross-sectional view thereof, FIG. 3 is a cross-sectional view showing an assembly operation of the pillar trim, and FIG. 4 is a rib for reinforcing the tether belt after the pillar trim is assembled. FIG. 5 is a sectional view showing a state when the curtain airbag is deployed, and FIG. 6 is a sectional view showing a state after deployment of the curtain airbag.

図１において、１はピラーインナパネルであって、その車室側内面にはカーテン式エアバッグ２とこれに連結されたテザーベルト３が車体前後方向に沿って配設されており、このピラーインナパネル１には樹脂製のフロントピラートリム４が車室内側から被着されている。即ち、ピラーインナパネル１には大小の矩形孔状の係合孔５と取付孔６が形成されている。他方、図２〜図６にも示すように、フロントピラートリム１の裏面には係合爪７とクリップ取付部８が車室外側方（図２〜図６の右方）に向かって一体に突設されており、図４に示すように、クリップ取付部８の先端に取り付けられたクリップ９をピラーインナパネル１に形成された前記取付孔６に差し込んでこれを係止することによってフロントピラートリム４がピラーインナパネル１に被着されている。   In FIG. 1, reference numeral 1 denotes a pillar inner panel. A curtain type airbag 2 and a tether belt 3 connected to the curtain airbag 2 are arranged along the vehicle body front-rear direction. 1, a resin-made front pillar trim 4 is attached from the vehicle interior side. That is, the pillar inner panel 1 is formed with a large and small rectangular hole-shaped engagement hole 5 and attachment hole 6. On the other hand, as shown in FIGS. 2 to 6, the engaging claw 7 and the clip mounting portion 8 are integrally projected on the rear surface of the front pillar trim 1 toward the outer side of the passenger compartment (the right side of FIGS. 2 to 6). As shown in FIG. 4, the front pillar trim 4 is formed by inserting a clip 9 attached to the tip of the clip attachment portion 8 into the attachment hole 6 formed in the pillar inner panel 1 and locking it. Is attached to the pillar inner panel 1.

ところで、フロントピラートリム４の裏面には補強用リブ１０が一体に形成されており、この補強用リブ１０に前記係合爪７が一体に形成されている。ここで、係合爪７は、クリップ取付部８よりも下方（カーテン式エアバッグ２が図３に示すように展開膨出した際にフロントピラートリム４とピラーインナパネル１との間に形成されリ開口部１１側）に設けられている。
Incidentally, a reinforcing rib 10 is integrally formed on the back surface of the front pillar trim 4, and the engaging claw 7 is integrally formed on the reinforcing rib 10. Here, the engaging claw 7 is lower than the clip portion 8 (curtain airbag 2 is formed between the CFCs preparative pillar trim 4 and the pillar inner panel 1 upon deployment bulged as shown in FIG. 3 (Re-opening portion 11 side).

又、図３〜図６に示すように、係合爪７の長さはクリップ取付部８の長さよりも長く設定されており、クリップ９の先端よりも突出する先端には四角柱状の係合部７ａが形成されている。そして、係合部７ａは下方に向かってＬ字状に屈曲されており、その下面には斜面状のガイド面７ａ−１が形成されている。   As shown in FIGS. 3 to 6, the length of the engaging claw 7 is set to be longer than the length of the clip mounting portion 8, and a square columnar engagement is provided at the tip protruding from the tip of the clip 9. Part 7a is formed. The engaging portion 7a is bent in an L shape downward, and an inclined guide surface 7a-1 is formed on the lower surface thereof.

而して、フロントピラートリム４をピラーインナパネル１に組み付ける前の図３に示す状態においては、ピラーインナパネル１にはカーテン式エアバッグ２とテザーベルト３が先付けされており、フロントピラートリム４は、図２及び図４に示すように、その裏面に一体に突設された係合爪７の先端部をピラーインナパネル１に形成された前記係合孔５に通し、前述のようにクリップ取付部８の先端に取り付けられたクリップ９をピラーインナパネル１に形成された取付孔６に差し込んでこれを係止することによって該フロントピラートリム１がピラーインナパネル１に取り付けられる。このとき、前述のように係合爪７をクリップ９の先端よりも突出させたため、フロントピラートリム４を組み付ける際に係合爪７がガイドとなり、フロントピラートリム４の組付作業性が高められる。そして、係合爪７の係合部７ａに斜面状のガイド面７ａ−１を形成したため、テザーベルト３の係合孔５への引き込みが防がれるとともに、フロントピラートリム４の組み付け時の係合部７ａの係合孔５への組み込みがスムーズになされ、フロントピラートリム４の組付作業性が更に高められる。   Thus, in the state shown in FIG. 3 before the front pillar trim 4 is assembled to the pillar inner panel 1, the curtain inner panel 1 is preceded by the curtain airbag 2 and the tether belt 3, and the front pillar trim 4 is As shown in FIGS. 2 and 4, the front end of the engaging claw 7 projecting integrally on the back surface thereof is passed through the engaging hole 5 formed in the pillar inner panel 1, and the clip mounting portion 8 as described above. The front pillar trim 1 is attached to the pillar inner panel 1 by inserting the clip 9 attached to the front end of the clip 9 into an attachment hole 6 formed in the pillar inner panel 1 and locking it. At this time, since the engaging claw 7 protrudes from the tip of the clip 9 as described above, the engaging claw 7 serves as a guide when the front pillar trim 4 is assembled, and the assembling workability of the front pillar trim 4 is improved. Since the inclined guide surface 7 a-1 is formed on the engaging portion 7 a of the engaging claw 7, the tether belt 3 is prevented from being pulled into the engaging hole 5 and the engaging portion when the front pillar trim 4 is assembled. 7a is smoothly assembled into the engagement hole 5, and the workability of assembling the front pillar trim 4 is further enhanced.

又、係合爪７がクリップ９の先端よりも突出するとともに、カーテン式エアバッグ２やテザーベルト３に近い側に係合爪７が配置されているため、フロントピラートリム４の組み付け時にクリップ取付部８にカーテン式エアバッグ２やテザーベルト３が近づくのが防がれ、クリップ取付部８へのテザーベルト３の噛み込み等が防がれる。そして、フロントピラートリム４がピラーインナパネル１に組み付けられた後には、図４に示すように、テザーベルト３は補強用リブ１０に沿って係合爪７の下方の所定位置に配置されている。   Further, since the engaging claw 7 protrudes from the tip of the clip 9 and the engaging claw 7 is disposed on the side close to the curtain airbag 2 or the tether belt 3, the clip mounting portion 8 is attached when the front pillar trim 4 is assembled. Thus, the curtain airbag 2 and the tether belt 3 are prevented from approaching, and the tether belt 3 is prevented from biting into the clip mounting portion 8. After the front pillar trim 4 is assembled to the pillar inner panel 1, the tether belt 3 is disposed at a predetermined position below the engaging claws 7 along the reinforcing rib 10 as shown in FIG. 4.

上記状態において車両が前方から衝撃を受けると、カーテン式エアバッグ２が展開膨張する。このとき、テザー」ベルト３がカーテン式エアバッグ２の展開膨張に伴ってフロントピラートリム４とピラーインナパネル１の間から引き出されるため、フロントピラートリム４はテザーベルト３苛ら力を受ける。個の力によって、フロンとピラートリム４は、その車両前方側に比較して車両後方側が大きく車室内側に移動し、図４に図示した断面において概略車両前方側を回転中心にして回転するよう移動する。つまり、個のカーテン式エアバッグ２の展開膨張によってフロントピラートリム４が車室内方の力を受けると、図５に示すように、クリップ９のピラーインナパネル１の取付孔６への係合が解除されてフロントピラートリム４が車室内方へと移動し、該フロントピラートリム４とピラーインナパネル１との間に開口部１１が形成される。このとき、フロントピラートリム４の裏面に一体に突設された係合爪７の係合部７ａが車両の下方側（開口部１１側）に向けて形成されているため、該係合部７ａがピラーインナパネル１の係合孔５の周縁に係合してフロントピラートリム４の移動を係合部７ａの係合孔５からの突出長さに規制するため、部品点数の増加を招くことなく、エアバッグ展開用の開口部１１を確保することができる程度のフロントピラートリム４の移動を許容しつつ、該フロントピラートリム４の車室内への飛び出しと脱落を防ぐことができる。
When the vehicle receives an impact from the front in the above state, the curtain airbag 2 is deployed and inflated. At this time, since the tether belt 3 is pulled out from between the front pillar trim 4 and the pillar inner panel 1 as the curtain airbag 2 is deployed and inflated, the front pillar trim 4 is subjected to the tether belt 3 irritation. Due to the individual forces, the CFC and the pillar trim 4 are moved so that the rear side of the vehicle is largely moved to the vehicle interior side compared to the front side of the vehicle, and rotates about the front side of the vehicle in the cross section shown in FIG. To do. That is, when the front pillar trim 4 receives a force in the vehicle compartment side by the deploying of the number of curtain airbag 2, as shown in FIG. 5, the engagement of the mounting holes 6 of the pillar inner panel 1 of the clip 9 The front pillar trim 4 is released to move toward the vehicle interior, and an opening 11 is formed between the front pillar trim 4 and the pillar inner panel 1. At this time, since the engaging portion 7a of the engaging claw 7 integrally protruding on the back surface of the front pillar trim 4 is formed toward the lower side (opening 11 side) of the vehicle, the engaging portion 7a is Engaging with the peripheral edge of the engagement hole 5 of the pillar inner panel 1 to restrict the movement of the front pillar trim 4 to the protruding length from the engagement hole 5 of the engagement portion 7a, without increasing the number of parts, While allowing the front pillar trim 4 to move to such an extent that the opening 11 for deploying the airbag can be secured, the front pillar trim 4 can be prevented from jumping out and dropping out.

特に、本実施の形態では、フロントピラートリム４の裏面に一体に突設されたクリップ取付部８よりもカーテン式エアバッグ２が展開膨出する開口部１１側に係合爪７を設けたため、カーテン式エアバッグ２が展開する際のフロントピラートリム４の移動の規制が確実に行われる。   In particular, in the present embodiment, since the engaging claw 7 is provided on the opening 11 side where the curtain airbag 2 is deployed and bulged from the clip mounting portion 8 integrally protruding on the back surface of the front pillar trim 4, the curtain The movement of the front pillar trim 4 when the type airbag 2 is deployed is reliably controlled.

又、係合爪７をフロントピラートリム４の裏面に形成された補強用リブ１０に一体に形成したため、部品点数が削減されるとともに、補強用リブ１０によって係合爪７の強度が高められ、カーテン式エアバッグ２が展開する際のフロントピラートリム４の移動規制が一層確実になされる。そして、係合爪７と補強用リブ１０によってテザーベルト３の位置や姿勢を規制することができ、カーテン式エアバッグ２の作動が一層確実になされ、フロントピラートリム４とピラーインナパネル１との間に形成された開口部１１からカーテン式エアバッグ２が車室内へと展開して乗員を衝撃から保護する。   Further, since the engaging claw 7 is integrally formed with the reinforcing rib 10 formed on the back surface of the front pillar trim 4, the number of parts is reduced, and the strength of the engaging claw 7 is increased by the reinforcing rib 10, so that the curtain The movement restriction of the front pillar trim 4 when the type airbag 2 is deployed is further ensured. Then, the position and posture of the tether belt 3 can be regulated by the engaging claws 7 and the reinforcing ribs 10, and the curtain airbag 2 can be operated more reliably, and between the front pillar trim 4 and the pillar inner panel 1. The curtain airbag 2 is deployed from the formed opening 11 into the passenger compartment to protect the occupant from impact.
