【発明の属する技術分野】
本発明は、被連結部材との間にエアバッグが配置された合成樹脂製の天井部材を被連結部材に取り付ける固定部材の構造に関する。
【０００２】
【従来の技術】
例えば乗用車や商用車等の車両においては、例えば図８に示すように、板状の天井部材１を、固定部材２１によってルーフフレーム６（被連結部材の一例）に取り付けることがある。固定部材２１は胴部２１ａ、胴部２１ａの一方の端部に備えられて胴部２１ａよりも幅広の頭部２１ｂ、胴部２１ａの他方の端部に備えられた取付部２１ｃを備えて構成されたものがある。
【０００３】
これによって、固定部材２１を天井部材１の取付口２に挿入し、固定部材２１の取付部２１ｃをルーフフレーム６の連結口７に挿入することによって、固定部材２１をルーフフレーム６に連結するのであり、固定部材２１の頭部２１ｂによって天井部材１が保持される。
【０００４】
【発明が解決しようとする課題】
例えば図８に示す構造によると天井部材１がルーフフレーム６に接触しておらず、ルーフフレーム６から所定間隔を置いて保持されるように、固定部材２１が構成されている。これは、天井部材１とルーフフレール６との間にカーテンエアバッグや衝撃吸収パッドを配置する車種に対応できるようにする為であり、天井部材１とルーフフレール６との間にカーテンエアバッグや衝撃吸収パッドを配置する車種、及び、天井部材１とルーフフレール６との間に何も配置しない車種に、固定部材２１が対応できるようにする為である。
【０００５】
前述のような固定部材を、天井部材と被連結部材との間に他の物を配置する状態、及び天井部材と被連結部材との間に何も配置しない状態の両方に対応させる場合、天井部材と被連結部材との間に何も配置しない状態において、例えば図８に示すように天井部材は固定部材の頭部に当て付けられるだけの状態となるので、例えば天井部材を手で押したりすると、天井部材が固定部材の頭部から被連結部材（ルーフフレーム）に変位するようなことがある。
本発明は、被連結部材から所定間隔を置いて天井部材が適切に保持されるような固定部材を得ることを目的としている。
【０００６】
【課題を解決するための手段】
［Ｉ］
請求項１の特徴によると、胴部と、胴部の一方の端部に備えられて胴部よりも幅広の頭部と、胴部の他方の端部に備えられた取付部とを備える。胴部から外方に離れた所定位置から胴部側に弾性的に変位可能な保持部を、胴部における取付部側の部分から胴部の外方に離れながら頭部に向かうように片持ち状に延出して構成する。所定の荷重が掛かると破断することによって胴部、頭部及び保持部が取付部から離脱することを許容する切欠き部分を、取付部における胴部に接する部分に備える。取付部を被連結部材に連結可能、被連結部材との間にエアバッグが配置された合成樹脂製の天井部材を頭部と保持部との間で保持可能に構成する。
【０００７】
これにより、請求項１の特徴によると、固定部材を天井部材の取付口に挿入しながら、固定部材の取付部を被連結部材に連結する際、固定部材の保持部が天井部材の取付口により所定位置から固定部材の胴部側に弾性的に変位して、天井部材の取付口への固定部材の挿入が、固定部材の保持部に邪魔されることなく行われる。天井部材の取付口を固定部材の保持部が通過すると、固定部材の保持部が所定位置側に復帰するのであり、固定部材の頭部と保持部との間で天井部材が挟まれて保持される。
【０００８】
従って、請求項１の特徴によると、固定部材により被連結部材から所定間隔を置いて天井部材が保持されるのであり、例えば天井部材を手で押したりしても、固定部材の保持部によって、天井部材が固定部材の頭部から被連結部材に変位するようなことは少ない。
【０００９】
［ＩＩ］
【００１０】
請求項１の特徴によると、前項［Ｉ］に記載のように、固定部材を天井部材の取付口に挿入していく際、固定部材の挿入に伴って天井部材の取付口により固定部材の保持部が、徐々に固定部材の胴部側に押されていく状態となるので（固定部材の胴部から外方に離れながら固定部材の頭部に向かうように、固定部材の保持部が片持ち状に延出されている点による）、固定部材の天井部材の取付口への挿入が抵抗少なく行われる。
【００１１】
請求項１の特徴によると、固定部材の頭部と保持部との間で天井部材が挟まれて保持された状態において、固定部材の保持部がつっかえ棒のように機能するので（固定部材の胴部から外方に離れながら固定部材の頭部に向かうように、固定部材の保持部が片持ち状に延出されている点による）、固定部材の頭部と保持部との間での挟み込みによる天井部材の保持が確実なものとなる。
【００１２】
［ＩＩＩ］
固定部材により被連結部材から所定間隔を置いて天井部材が保持された状態において、天井部材と被連結部材との間に例えばカーテンエアバッグを配置した場合、カーテンエアバッグが膨張して天井部材が押しひろげられると、固定部材が破壊されて、破壊された固定部材が車内に飛散するおそれがある。
【００１３】
【００１４】
請求項１の特徴によると、前述のようにカーテンエアバッグが膨張して天井部材が押しひろげられると、切欠き部分が破断して、固定部材の胴部、頭部及び保持部が固定部材の取付部から離脱し、固定部材の取付部が被連結部材に残される。
この場合、請求項１の特徴によると、固定部材の頭部と保持部との間で天井部材が挟まれて保持されているので、固定部材が天井部材から離れることはなく、固定部材が車内に飛散するような状態は生じない。
【００１５】
【発明の実施の形態】
図１及び図２は５ドア型式の乗用車等の車両において、天井部材１を示しており、天井部材１は合成樹脂により１枚の板状に一体的に形成され、天井部材１の外周部に複数の丸形の取付口２が備えられている。フロントドア３、リヤドア４及びリヤクォーターガラス５の上部に、右及び左のルーフフレーム６が車体の前後方向に配置されており、天井部材１をルーフフレーム６に固定する。図３に示すように、ルーフフレーム６に複数の丸形の連結口７が備えられている。
【００１６】
次に、ルーフフレーム６から所定間隔を置いて天井部材１を保持する固定部材８について説明する。
図３及び図４に示すように、胴部９、胴部９の一方の端部に備えられて胴部９よりも幅広の頭部１０、胴部９の他方の端部に備えられた第１取付部１１及び第２取付部１２、保持部１３を備えて、固定部材８が合成樹脂により一体的に形成されている。胴部９は４枚の平板部分９ａを直角に交差させたような断面十字状に構成され、平板状の円盤部分９ｂが平板部分９ａに接続されている。頭部１０は胴部９の平板部分９ａよりも大きな半径を備えた円形の笠状に構成されて、胴部９の平板部分９ａに接続されている。
【００１７】
図３及び図４に示すように、保持部１３は胴部９の平板部分９ａの間に位置するように胴部９の円盤部分９ｂに接続されており、胴部９の円盤部分９ｂから、胴部９の平板部分９ａから外方に離れながら頭部１０に向かうように、片持ち状に延出されて構成されている。保持部１３の先端部１３ａがクサビ状に先細り状に形成されており、先端部１３ａに１／４円状のフランジ部１３ｂが形成されている。
【００１８】
図３，４，５に示すように、第１取付部１１は４枚の平板部分１１ａを直角に交差させたような断面十字状に構成され、平板部分１１ａが胴部９の円盤部分９ｂに接続されており、１／４の笠状の係合部分１１ｂが４枚の平板部分１１ａの間の各々に複数個形成されている。第１取付部１１の外径が、胴部９の平板部分１１ａ及び円盤部分１１ｂよりも少し小さなものとなっている。
【００１９】
図３及び図４に示すように、第２取付部１２は４枚の平板部分１２ａを直角に交差させたような断面十字状に構成されて、平板部分１２ａが第１取付部１１に接続されており、１／４の笠状の係合部分１２ｂが４枚の平板部分１２ａの間の各々に複数個形成されている。先端部分１２ｃが先細り状に構成されており、第２取付部１２の外径が第１取付部１１よりも少し小さなものとなっている。
【００２０】
以上のように構成された固定部材８を使用して、天井部材１をルーフフレーム６に以下のようにして取り付ける。
図３に示すように、ルーフフレーム６に沿ってカーテンエアバッグ１４を配置し、天井部材１をルーフフレーム６及びカーテンエアバッグ１４に沿って配置する。この状態で固定部材８を天井部材１の取付口２に第２取付部１２から挿入していき、第１及び第２取付部１１，１２をルーフフレーム６の連結口７に挿入していく。
【００２１】
図３及び図５に示すように、ルーフフレーム６の連結口７の内径が、第１取付部１１の平板部分１１ａの外径と略同じもの（又は少し大きなもの）に設定されており、第１取付部１１の係合部分１１ｂの外径がルーフフレーム６の連結口７の内径よりも大きなものに設定されている。これにより、固定部材８を天井部材１の取付口２に挿入し、第１及び第２取付部１１，１２をルーフフレーム６の連結口７に挿入する際、第２取付部１２がルーフフレーム６の連結口７を通過した後、第１取付部１１の平板部分１１ａはルーフフレーム６の連結口７を通過するが、第１取付部１１の係合部分１１ｂはルーフフレーム６の連結口７に当たって弾性変形しながら通過する。従って、胴部９の円盤部分９ｂがルーフフレーム６に当たるまで固定部材８を挿入することによって、胴部９の円盤部分９ｂと第１取付部１１の係合部分１１ｂとの間で、ルーフフレーム６が挟まれて保持された状態となって、固定部材８がルーフフレーム６に連結される。
【００２２】
固定部材８を天井部材１の取付口２に挿入していく際、保持部１３が天井部材１の取付口２に達すると、固定部材８の挿入に伴って天井部材１の取付口２により保持部１３が、胴部９から外方に離れた所定位置（図４に示す位置）から胴部９に接近するように押されて弾性変形していき、胴部９の平板部材９ａの間に保持部１３が入り込んで、保持部１３が天井部材１の取付口２を通過する。
【００２３】
図３に示すように、保持部１３の先端部１３ａが天井部材１の取付口２を通過すると、保持部１３が所定位置（図３に示す位置）に戻り、保持部１３の先端部１３ａが天井部材１の取付口２の外周部に当たる。これにより、固定部材８において、頭部１０と保持部１３（先端部１３ａ）との間で、天井部材１が挟まれて保持された状態となるので、天井部材１が押されても（図３の紙面右方）、天井部材１は変位し難い。
【００２４】
この場合、図３に示すように、天井部材１が押された際（図３の紙面右方）、保持部１３の先端部１３ａが天井部材１の取付口２に入り込むが、保持部１３のフランジ部１３ｂが天井部材１の取付口２の外周部に当たって、保持部１３がつっかえ棒のように機能する点、並びに保持部１３の先端部１３ａが天井部材１の取付口２に少し入り込んで、保持部１３の先端部１３ａが天井部材１の取付口２から外れ難い点により、固定部材８による天井部材１の保持が確実なものとなっている。
【００２５】
以上のようにして、図３に示すように、固定部材８により天井部材１がルーフフレーム６から所定間隔（胴部９の長さの間隔）を置いて保持される。
ルーフフレーム６の連結口７の内径が、第２取付部１２の平板部分１２ａの外径と略同じもの（又は少し大きなもの）に設定されていると、固定部材８において第１取付部１１はルーフフレーム６の連結口７に挿入されず、第１取付部１１の端部と第２取付部１２の係合部分１２ｂとの間で、ルーフフレーム６が挟まれて保持された状態となって、固定部材８がルーフフレーム６に連結される。これにより、固定部材８により天井部材１が、ルーフフレーム６から所定間隔（胴部９及び第１取付部１１の長さの間隔）を置い保持される。この後、ウェザーストリップ１５をルーフフレーム６に取り付ける。
【００２６】
［発明の実施の第１別形態］
前述の［発明の実施の形態］において、第１取付部１１の係合部分１１ｂの外径（第２取付部１２の係合部分１２ｂの外径）を少し小さなものに設定して、第１取付部１１の係合部分１１ｂの外径（第２取付部１２の係合部分１２ｂの外径）がルーフフレーム６の連結口７の内径よりも大きなものとなるが、第１取付部１１の係合部分１１ｂの外径（第２取付部１２の係合部分１２ｂの外径）とルーフフレーム６の連結口７の内径との差を、前述の［発明の実施の形態］よりも小さくしてもよい。
従って、頭部１０の強度及び胴部９の強度よりも、ルーフフレーム６の連結口７への固定部材８（第１及び第２取付部１１，１２）の連結強度が小さなものとなるように構成する。
【００２７】
これにより図６に示すように、カーテンエアバッグ１４が膨張して天井部材１を押しのけると、固定部材８において頭部１０や胴部９が破断される前に、第１取付部１１（第２取付部１２）がルーフフレーム６の連結口７から抜けるのであり、頭部１０と保持部１３との間で天井部材１が挟まれて保持された状態となっていることにより、固定部材８が天井部材１から離れることはなく、固定部材８が車内に飛散するような状態は生じない。
【００２８】
［発明の実施の第２別形態］
前述の［発明の実施の第１別形態］に代えて、次のように構成してもよい。
図７（イ）に示すように、固定部材８において第１取付部１１（平板部分１１ａ）における胴部９の円盤部分９ｂに接する部分、第２取付部１２（平板部分１２ａ）における第１取付部１１に接する部分に、切欠き部分１１ｃ，１２ｄを備えたり、図７（ロ）に示すように、固定部材８において第１取付部１１（平板部分１１ａ）における胴部９の円盤部分９ｂに接する部分、第２取付部１２（平板部分１２ａ）における第１取付部１１に接する部分に、円弧部分１１ｄ，１２ｅを備える。
【００２９】
この場合、図７（イ）に示す切欠き部分１１ｃ，１２ｄ及び図７（ロ）に示す円弧部分１１ｄ，１２ｅの両方を、互いに位相が１８０°異なるように同時に備えてもよい。保持部１３を胴部９の中間付近に備えた場合には、胴部９の円盤部分９ｂと保持部１３との間の胴部９の部分（平板部分１１ａ）に、切欠き部分１１ｃを備えてもよい。
従って、切欠き部分１１ｃ，１２ｄを備えた場合は、切欠き部分１１ｃ，１２ｄが脆弱部分となるのであり、切欠き部分１１ｃ，１２ｄを備えずに円弧部分１１ｄ，１２ｅを備えた場合は、円弧部分１１ｄ，１２ｅとは反対側の部分（平板部分１１ａ，１２ａ）が、脆弱部分となる。
【００３０】
これにより、図３に示す状態においてカーテンエアバッグ１４が膨張して天井部材１を押しのけると、図７（ハ）に示すように固定部材８において頭部１０や胴部９が破断される前に、第１取付部１１の切欠き部分１１ｃ（第１取付部１１の円弧部分１１ｄとは反対側の部分（平板部分１１ａ））が破断して、第１及び第２取付部１１，１２がルーフフレーム６に残されるのであり、頭部１０と保持部１３との間で天井部材１が挟まれて保持された状態となっていることにより、胴部９、頭部１０及び保持部１３が天井部材１から離れることはなく、胴部９、頭部１０及び保持部１３が車内に飛散するような状態は生じない。
【００３１】
第１取付部１１の端部と第２取付部１２の係合部分１２ｂとの間で、ルーフフレーム６が挟まれて保持された状態において、前述のようにカーテンエアバッグ１４が膨張して天井部材１を押しのけると、固定部材８において頭部１０や胴部９、第１取付部１１の切欠き部分１１ｃ（第１取付部１１の円弧部分１１ｄとは反対側の部分（平板部分１１ａ））が破断される前に、第２取付部１２の切欠き部分１２ｃ（第２取付部１２の円弧部分１２ｅとは反対側の部分（平板部分１２ａ））が破断して、第２取付部１２がルーフフレーム６に残されるのであり、頭部１０と保持部１３との間で天井部材１が挟まれて保持された状態となっていることにより、胴部９、頭部１０及び保持部１３、第１取付部１１が天井部材１から離れることはなく、胴部９、頭部１０及び保持部１３、第１取付部１１が車内に飛散するような状態は生じない。
【００３２】
第１取付部１１の切欠き部分１１ｃ（第１取付部１１の円弧部分１１ｄとは反対側の部分（平板部分１１ａ））が破断される前に、第２取付部１２の切欠き部分１２ｃ第２取付部１２の円弧部分１２ｅとは反対側の部分（平板部分１２ａ））が破断するのは、第２取付部１２（平板部分１２ａ）の外径が第１取付部１１（平板部分１１ａ）の外径よりも小さいことによる。
【００３３】
［発明の実施の第３別形態］
前述の［発明の実施の第１別形態］の構成及び［発明の実施の第２別形態］の構成の両方を、固定部材８に備えるように構成してもよい。前述の［発明の実施の形態］及び［発明の実施の第１別形態］、［発明の実施の第２別形態］において、カーテンエアバッグ１４に代えて、衝撃吸収パッド（図示せず）を配置するように構成してもよく、天井部材１とルーフフレーム６との間に何も配置しないように構成してもよい。
本発明の固定部材８は天井部材１に対してばかりではなく、ドアの内側の樹脂パネルやトランクルームの内張りの取付等に使用することができる。

The fixing member 21 includes a body portion 21a, a head portion 21b that is provided at one end of the body portion 21a and wider than the body portion 21a, and an attachment portion 21c that is provided at the other end portion of the body portion 21a. There is something that was done.
[0003]
What I thereto, the fixing member 21 is inserted into the mounting hole 2 of the roof member 1, by inserting the mounting portion 21c of the fixing member 21 to the connecting port 7 of the roof frame 6, the fixing member 21 to the roof frame 6 The ceiling member 1 is held by the head portion 21 b of the fixing member 21.
[0004]
[Problems to be solved by the invention]
For example not in contact with the ceiling member 1 roof frame 6 when by the structure shown in FIG. 8, to be held from the roof frame 6 at predetermined intervals, the fixing member 21 is formed. This is in order to be able to cope with a vehicle type in which a curtain airbag or a shock absorbing pad is arranged between the ceiling member 1 and the roof flail 6, and between the ceiling member 1 and the roof flail 6, This is because the fixing member 21 can correspond to a vehicle type in which the shock absorbing pad is arranged and a vehicle type in which nothing is arranged between the ceiling member 1 and the roof flail 6.
[0005]
When the fixing member as described above, correspond to both the state without placing anything between the states, and the ceiling member and the connecting member to place other things between the ceiling member and the member to be connected, the ceiling when no place anything in between the member and the member to be connected, the ceiling member as shown in FIG. 8 example, since only the state is abutting the head of the fixing member, or press such as ceiling member by hand Then, the ceiling member may be displaced from the head of the fixing member to the connected member (roof frame).
An object of the present invention is to obtain a fixing member that allows a ceiling member to be appropriately held at a predetermined interval from a connected member.
[0006]
[Means for Solving the Problems]
[I]
According to a first aspect of the present invention, the body includes a body, a head that is provided at one end of the body and is wider than the body, and an attachment that is provided at the other end of the body. A holding part that is elastically displaceable from a predetermined position away from the torso to the torso side, and cantilevered toward the head while being away from the attaching part side of the torso to the outside of the torso It is configured to extend into a shape. A notch part that allows the body part, the head part, and the holding part to be detached from the attachment part by breaking when a predetermined load is applied is provided in a part in contact with the body part in the attachment part . The mounting portion can be connected to the connected member, and the synthetic resin ceiling member in which the airbag is disposed between the attached member and the connected member can be held between the head portion and the holding portion.
[0007]
Thus, according to the first aspect of the present invention, when the fixing member is inserted into the attachment port of the ceiling member and the attachment portion of the fixing member is connected to the connected member, the holding portion of the fixing member is connected to the attachment port of the ceiling member. The fixing member is elastically displaced from the predetermined position toward the body portion of the fixing member, and the fixing member is inserted into the mounting opening of the ceiling member without being obstructed by the holding portion of the fixing member. When the holding portion of the fixing member passes through the mounting opening of the ceiling member , the holding portion of the fixing member returns to the predetermined position side, and the ceiling member is sandwiched and held between the head of the fixing member and the holding portion. The
[0008]
Therefore, according to the feature of claim 1, the ceiling member is held at a predetermined distance from the connected member by the fixing member. For example, even if the ceiling member is pushed by hand, the holding portion of the fixing member It is rare that the ceiling member is displaced from the head of the fixing member to the connected member.
[0009]
[II]
[0010]
According to the feature of claim 1 , when the fixing member is inserted into the mounting port of the ceiling member as described in the preceding item [I], the fixing member is held by the mounting port of the ceiling member as the fixing member is inserted. Part is gradually pushed toward the body side of the fixing member (the holding part of the fixing member cantilevered toward the head of the fixing member while leaving outward from the body part of the fixing member). Insertion of the fixing member into the mounting opening of the ceiling member is performed with less resistance.
[0011]
According to the feature of the first aspect, in the state where the ceiling member is sandwiched and held between the head of the fixing member and the holding portion, the holding portion of the fixing member functions like a holding rod (of the fixing member). The holding part of the fixing member is extended in a cantilevered manner so as to go to the head of the fixing member while leaving outward from the body part), between the head of the fixing member and the holding part The ceiling member can be securely held by the sandwiching.
[0012]
[III]
In the state where the ceiling member is held at a predetermined distance from the connected member by the fixing member , for example, when a curtain airbag is disposed between the ceiling member and the connected member, the curtain airbag is inflated and the ceiling member is When pushed, the fixing member is destroyed, and the destroyed fixing member may be scattered in the vehicle.
[0013]
[0014]
According to the first aspect of the present invention, when the curtain airbag is inflated and the ceiling member is pushed and expanded as described above, the cutout portion is broken and the body portion, the head portion, and the holding portion of the fixing member are The attachment part of the fixing member is left on the connected member.
In this case, according to the feature of the first aspect, since the ceiling member is sandwiched and held between the head portion of the fixing member and the holding portion, the fixing member does not leave the ceiling member, and the fixing member is in the vehicle. There is no state of splashing.
[0015]
