More specifically, the present invention relates to a support member assembly structure for attaching a support member for attaching an interior part provided on the roof side of a vehicle to a roof side rail of the vehicle.

特許文献１には、カーテンエアバッグ装置のインフレータを固定するブラケットとグラブハンドルを取り付ける支持部材を組付けボルトで一体にすることで、カーテンエアバッグ装置をルーフサイドレールに取り付けると同時に支持部材を車両に配置する構造が知られている。
また、特許文献２には、グラブレール（グラブハンドル）を取り付けるための一対の部品取付座の間にエアバッグ装置の固定部を取り付けるためのバッグ取付座を設けて、一体にしたブラケットが知られている。 In Patent Document 1, a bracket for fixing an inflator of a curtain airbag device and a support member for attaching a grab handle are integrated with an assembly bolt, whereby the curtain airbag device is attached to a roof side rail and at the same time the support member is attached to the vehicle. is known.
Further, in Patent Document 2, a bracket is known in which a bag mounting seat for mounting a fixing portion of an airbag device is provided between a pair of component mounting seats for mounting a grab rail (grab handle). ing.

米国特許８４３９３９２号明細書U.S. Pat. No. 8,439,392 特開２００８－３０２８８９号公報Japanese Patent Application Laid-Open No. 2008-302889

特許文献１に記載の構造の場合、カーテンエアバッグ装置のインフレータを固定するブラケットとグラブハンドルを取り付ける支持部材が組付けボルトで一体化されていることから、インフレータの位置とグラブハンドルの位置を合わせなければならない。しかしながら、インフレータの位置とグラブハンドルの位置が別々に設計される場合にはこの構造を適用することができず、この構造は設計上の自由度が低い構造といえる。 In the case of the structure described in Patent Document 1, since the bracket for fixing the inflator of the curtain airbag device and the support member for attaching the grab handle are integrated with assembly bolts, the position of the inflator and the position of the grab handle are aligned. There must be. However, when the position of the inflator and the position of the grab handle are designed separately, this structure cannot be applied, and it can be said that this structure has a low degree of freedom in design.

特許文献２に記載の構造の場合、ブラケットを車両に取り付ける車両取付座は、ブラケットの両端に設けられた２か所のみであるため、エアバッグの膨張展開時の勢いによってバッグ取付座が車室内側へ引っ張られてブラケットが変形し、エアバッグが所望の位置に展開しないおそれがある。また、バッグ取付座がルーフサイドレールから離れていることで、エアバッグをバッグ取付座に取り付ける際に、側方延出部が変形することで部品取付座の位置が所定の位置からずれてしまい、グラブレールを部品取付座に取りつけられないおそれがある。また、あらかじめカーテンエアバッグ装置とブラケットとを一体にした状態で車両に取り付ける場合も、カーテンエアバッグ装置の重さでブラケットが変形するおそれがある。 In the case of the structure described in Patent Document 2, there are only two vehicle mounting seats provided at both ends of the bracket for mounting the bracket to the vehicle. The bracket may be deformed by being pulled inward, and the airbag may not deploy to the desired position. In addition, since the bag mounting seat is separated from the roof side rail, when the airbag is mounted on the airbag mounting seat, the laterally extending portion deforms, causing the part mounting seat to shift from the predetermined position. , the grab rail may not be attached to the part mounting seat. Further, when the curtain airbag device and the bracket are integrated in advance and attached to the vehicle, the weight of the curtain airbag device may deform the bracket.

本発明は、上記課題に鑑みてなされたものであり、支持部材を車両に取り付けることができ、かつ、内装部品を取り付けるための支持部材の変形を抑制することができる、支持部材組付構造を提供することを目的とする。 SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a support member assembly structure that allows a support member to be attached to a vehicle and that can suppress deformation of the support member for attaching interior parts. intended to provide

If the first reinforcing portion 35 is provided between the first fixing portion 11 and the second fixing portion 12 of the first supporting member 10, the first fixing portion 11 of the first supporting member 10 and the Since the space between the second fixing portions 12 is fixed by the first reinforcing portion 35, deformation of the first support member 10 is suppressed.

また、支持部材組付構造１では、第２の支持部材２０の一対の固定部である第３の固定部２３と第４の固定部２４は、インフレータブラケット５０に一体的に形成された第２の補強部５５により連結されている。
図２において、インフレータブラケット５０のうち、第２の支持部材２０の第３の固定部２３と第４の固定部２４の間を連結する部位が第２の補強部５５となる。図２には第２の補強部５５の位置の概略を網掛けで示している。
第２の支持部材２０の第３の固定部２３と第４の固定部２４の間に第２の補強部５５が設けられていると、第２の支持部材２０の第３の固定部２３と第４の固定部２４の間隔が第２の補強部５５により固定されるので、第２の支持部材２０が変形することが抑制される。 In addition, in the support member assembly structure 1 , the third fixing portion 23 and the fourth fixing portion 24 , which are a pair of fixing portions of the second support member 20 , are formed integrally with the inflator bracket 50 . are connected by a reinforcing portion 55 of
In FIG. 2 , a portion of the inflator bracket 50 that connects the third fixing portion 23 and the fourth fixing portion 24 of the second support member 20 is a second reinforcing portion 55 . In FIG. 2, the outline of the position of the second reinforcing portion 55 is indicated by shading.

すなわち、第１実施形態の支持部材組付構造では、第１の支持部材がルーフサイドレールに固定される部位である第１の固定部と第２の固定部の間が第１の補強部により補強され、かつ、第２の支持部材がルーフサイドレールに固定される部位である第３の固定部と第４の固定部の間が第２の補強部により補強されている。このように第１の支持部材と第２の支持部材がそれぞれルーフサイドレールに固定される部位の間が補強されているので、エアバッグの膨張展開時やエアバッグの車両への組付時に第１の支持部材と第２の支持部材が変形することが抑制される。 That is, in the support member assembly structure of the first embodiment, the first reinforcing portion is provided between the first fixing portion and the second fixing portion, which are the portions where the first support member is fixed to the roof side rail. A portion between the third fixing portion and the fourth fixing portion which is reinforced and where the second support member is fixed to the roof side rail is reinforced by the second reinforcing portion. Since the portions between the first support member and the second support member fixed to the roof side rails are reinforced in this way, when the airbag is inflated and deployed or when the airbag is assembled to the vehicle, the Deformation of the first support member and the second support member is suppressed.

本発明の支持部材組付構造では、第１の支持部材、第２の支持部材、連結部材及びカーテンエアバッグ装置（インフレータブラケット）が別々の部材であり、これらの部材が組み合わされて支持部材組付構造を構成している。
そして、本発明の支持部材組付構造では、連結部材の板厚と支持部材の板厚が異なっていてもよい。
支持部材に取り付ける内装部品が異なると、支持部材に要求される強度が異なることから、支持部材を構成する板材の板厚を変更する必要がある。この場合、支持部材と連結部材が一体となった部材であると支持部材の板厚の変更に合わせて連結部材の厚さを変更する必要があるが、連結部材側にも要求される厚さが別の理由で存在することから、支持部材と連結部材の厚さを同じにできるとは限らない。
支持部材と連結部材を別々の部材としておき、後で接合して支持部材組付構造とすることにより、支持部材の仕様が異なる場合であっても共通の連結部材を使用することができる。 In the support member assembly structure of the present invention, the first support member, the second support member, the connecting member, and the curtain airbag device (inflator bracket) are separate members, and these members are combined to form a support member assembly. It constitutes an attached structure.
Further, in the support member assembly structure of the present invention, the plate thickness of the connecting member and the plate thickness of the support member may be different.
If the interior parts to be attached to the support member are different, the strength required of the support member will be different. Therefore, it is necessary to change the plate thickness of the plate material that constitutes the support member. In this case, if the supporting member and the connecting member are integral members, it is necessary to change the thickness of the connecting member according to the change in the plate thickness of the supporting member. exists for another reason, the thickness of the supporting member and the connecting member cannot always be the same.
By forming the supporting member and the connecting member as separate members and joining them later to form a supporting member assembly structure, it is possible to use a common connecting member even if the specifications of the supporting members are different.

また、同様の理由により、本発明の支持部材組付構造では、インフレータブラケットの板厚と支持部材の板厚が異なっていてもよい。
このように、支持部材組付構造を構成する支持部材、連結部材及びインフレータブラケットの厚さをそれぞれの部材に適した厚さにすることができる点で、支持部材と連結部材やインフレータブラケットを一体成型した支持部材組付構造を使用する場合と比較して、本発明の支持部材組付構造は有利な構造であるといえる。 For the same reason, in the support member assembly structure of the present invention, the plate thickness of the inflator bracket and the plate thickness of the support member may be different.
In this way, the thicknesses of the supporting member, the connecting member, and the inflator bracket, which constitute the supporting member assembly structure, can be made suitable for each member. It can be said that the support member assembly structure of the present invention is an advantageous structure compared to the case of using a molded support member assembly structure.

例えば、支持部材の板厚を連結部材の板厚より厚く又は薄くすることが好ましい。また、支持部材の板厚をインフレータブラケットの板厚より厚く又は薄くすることが好ましい。
また、具体的な厚さの例として、支持部材の板厚が１．０～２．０ｍｍであり、連結部材の板厚が１．２～２．０ｍｍであり、インフレータブラケットの板厚が１．２～２．０ｍｍであってもよい。
また、支持部材、連結部材及びインフレータブラケットの板厚が同じであってもよい。 For example, it is preferable to make the plate thickness of the supporting member thicker or thinner than the plate thickness of the connecting member. Further, it is preferable that the thickness of the support member is thicker or thinner than that of the inflator bracket.
Further, as specific examples of thickness, the plate thickness of the support member is 1.0 to 2.0 mm, the plate thickness of the connecting member is 1.2 to 2.0 mm, and the plate thickness of the inflator bracket is 1.0 mm. .2 to 2.0 mm.
Further, the plate thicknesses of the supporting member, the connecting member, and the inflator bracket may be the same.

なお、支持部材、連結部材及びインフレータブラケットを構成する板材は亜鉛めっき鋼板等の材質とすることができる。
また、支持部材を補強する観点から、連結部材及びインフレータブラケットを構成する板材の材質を、支持部材を構成する板材よりも強度の強い材質としてもよい。例えば、冷間圧延鋼板等が挙げられる。 The plate materials that constitute the support member, the connecting member, and the inflator bracket can be made of a material such as a galvanized steel plate.
Further, from the viewpoint of reinforcing the support member, the material of the plate material that constitutes the connecting member and the inflator bracket may be a material having a higher strength than the plate material that constitutes the support member. For example, a cold-rolled steel plate etc. are mentioned.

本発明の支持部材組付構造において、連結部材には、車両のルーフサイドレールに取り付けられるクリップを嵌合するための嵌合孔が設けられていてもよい。
図６Ａは、クリップの一例を模式的に示す斜視図であり、図６Ｂは、連結部材の嵌合孔にクリップを嵌合させた状態を模式的に示す斜視図である。
図６Ａに示すクリップ６０は全体として円筒形であり、円筒６３の両端に、切り欠きを有する円環板６１、６２が設けられた形態となっている。 In the support member assembly structure of the present invention, the connecting member may be provided with a fitting hole for fitting a clip attached to the roof side rail of the vehicle.
FIG. 6A is a perspective view schematically showing an example of a clip, and FIG. 6B is a perspective view schematically showing a state in which the clip is fitted into the fitting hole of the connecting member.
The clip 60 shown in FIG. 6A has a cylindrical shape as a whole, and has a configuration in which annular plates 61 and 62 having notches are provided at both ends of a cylinder 63 .

図６Ｂに示すように、連結部材３０は嵌合孔３６を有している。嵌合孔３６は径の大きな孔である大径孔３６ａと径の小さな孔である小径孔３６ｂを組み合わせてなる孔であり、クリップ６０を大径孔３６ａに入れてから小径孔３６ｂ側にずらすことでクリップ６０を嵌合孔３６に嵌合させることができる。
なお、クリップ６０を嵌合させていない嵌合孔３６、大径孔３６ａ及び小径孔３６ｂの形状は図４にも示している。 As shown in FIG. 6B, the connecting member 30 has a fitting hole 36. As shown in FIG. The fitting hole 36 is a hole formed by combining a large-diameter hole 36a and a small-diameter hole 36b. After inserting the clip 60 into the large-diameter hole 36a, it is shifted to the small-diameter hole 36b side. Thus, the clip 60 can be fitted into the fitting hole 36 .
The shapes of the fitting hole 36, the large-diameter hole 36a, and the small-diameter hole 36b to which the clip 60 is not fitted are also shown in FIG.

上記説明のようにクリップ６０を嵌合孔３６に嵌合させる場合、クリップの円環板６１と円環板６２の間隔と連結部材３０の板厚を略同じとする。または、連結部材３０の板厚を少し小さくする。
クリップ６０における円環板６１と円環板６２の間隔はクリップの仕様上所定の範囲に定める必要があるので、連結部材３０の板厚をクリップ６０の仕様に合わせた板厚にするようにする。
この場合、連結部材３０と第１の支持部材１０及び第２の支持部材２０は別部材からなるので、第１の支持部材１０及び第２の支持部材２０の板厚は支持部材に要求される板厚として定めて、連結部材３０の板厚はクリップ６０の仕様に合わせた板厚として定めることができる。 When the clip 60 is fitted into the fitting hole 36 as described above, the interval between the annular plates 61 and 62 of the clip and the plate thickness of the connecting member 30 are made substantially the same. Alternatively, the plate thickness of the connecting member 30 is slightly reduced.
Since the interval between the annular plate 61 and the annular plate 62 in the clip 60 must be set within a predetermined range according to the specifications of the clip, the plate thickness of the connecting member 30 is set to match the specifications of the clip 60. .
In this case, since the connection member 30 and the first support member 10 and the second support member 20 are made of separate members, the plate thickness of the first support member 10 and the second support member 20 is required for the support members. By determining the plate thickness, the plate thickness of the connecting member 30 can be determined as a plate thickness that matches the specifications of the clip 60 .

例えば、クリップを嵌合させる連結部材の板厚を１．７～２．０ｍｍとし、グラブハンドルを支持する支持部材の板厚を１．０～２．０ｍｍとすることができる。 For example, the plate thickness of the connecting member to which the clip is fitted can be 1.7 to 2.0 mm, and the plate thickness of the supporting member for supporting the grab handle can be 1.0 to 2.0 mm.

クリップ６０は、樹脂製のクリップであることが好ましく、車両のボディにはクリップを嵌合させる部位が設けられているのでクリップを車両のボディに直接嵌めこむことができる。クリップを嵌めこむことにより、支持部材組付構造を車両に仮固定することができる。
そして、クリップにより、車両のルーフサイドレールに取り付ける部品を固定することができる。クリップにより固定する部品としては、ドレンホース、電子部品のハーネス等が挙げられる。 The clip 60 is preferably a resin clip, and since the body of the vehicle is provided with a portion for fitting the clip, the clip can be directly fitted into the body of the vehicle. By fitting the clip, the support member assembly structure can be temporarily fixed to the vehicle.
Then, the clip can be used to fix a component to be attached to the roof side rail of the vehicle. A drain hose, a harness for electronic parts, and the like are examples of the parts fixed by the clip.

本発明の支持部材組付構造において、カーテンエアバッグ装置は、インフレータと、インフレータを固定するインフレータブラケットとを備え、インフレータブラケットが連結部材の第２の端部及び第２の支持部材に取り付けられることが好ましい。 In the supporting member assembly structure of the present invention, the curtain airbag device includes an inflator and an inflator bracket for fixing the inflator, and the inflator bracket is attached to the second end of the connecting member and the second supporting member. is preferred.

As shown in FIG. 7A, the inflator 70 is mounted on the inflator fixing portion 52 of the inflator bracket 50, and the inflator 70 is fixed to the inflator fixing portion 52 by inserting fixing pins into the inflator fixing holes 52a and 52b. be.
As shown in FIG. 7B, the inflator fixing portion 52 fixes the inflator 70 at a position protruding inward in the vehicle width direction (direction of arrow IN in FIG. 7A).
7A and 7B show a cylindrical inflator as the inflator, but the shape of the inflator is not particularly limited.

インフレータ及びインフレータブラケットは、剛性のある（強度の高い）部材である。そのため、ルーフサイドレールに支持部材組付構造を取り付ける際に、インフレータを持ってインフレータブラケットから取り付けるようにすると、支持部材組付構造を取り付ける際の作業性を向上させることができる。 The inflator and the inflator bracket are rigid (strong) members. Therefore, when attaching the support member assembly structure to the roof side rail, if the inflator is held and attached from the inflator bracket, workability in attaching the support member assembly structure can be improved.
