Description

本発明は、車両へエアバッグ装置の組み付けるためのエアバッグ装置組付構造及び部材同士の組付構造に関する。   The present invention relates to an airbag apparatus assembly structure for assembling an airbag apparatus to a vehicle and an assembly structure of members.

特許文献１に開示されている膝用のエアバッグ装置（ニーエアバッグ装置）では、エアバッグ装置の取付ブラケットがボルトにより車両の支持体に締結固定されている。
特開２００４−３５２１１９の公報 In the knee airbag device (knee airbag device) disclosed in Patent Document 1, a mounting bracket of the airbag device is fastened and fixed to a vehicle support body by a bolt.
JP 2004-352119 A

ところで、上記のようにエアバッグ装置の取付ブラケットと車両の支持体とをボルトで締結固定する構成の他に、支持体及び取付ブラケットの何れかの一方に形成された孔部に対して、何れかの他方に形成された係止爪（クリップ）を嵌合させて結合する構成がある。このような係止爪の嵌合による結合構造では、係合爪の嵌合状態で、孔部に対する係止爪の進入方向とは反対側の係合爪の面と、孔部の周囲の面とが対向することで抜け止めとなり、取付ブラケットが支持体に固定される。   By the way, in addition to the configuration in which the mounting bracket of the airbag device and the vehicle support are fastened and fixed with bolts as described above, any of the holes formed in one of the support and the mounting bracket There is a configuration in which locking claws (clips) formed on the other side are fitted and coupled. In such a coupling structure by engagement of the engaging claws, in the engaged state of the engaging claws, the surface of the engaging claws on the opposite side to the direction in which the engaging claws enter the hole, and the surface around the hole And the mounting bracket is fixed to the support.

このような係合爪による結合構造では、エアバッグ装置が作動することを考慮すると孔部から係合爪が抜け難く結合強度が強い方がよい。一方で、例えば、車両のメンテナンス等でエアバッグ装置を取り外すことを考慮した場合、係合爪が孔部から抜け難いとメンテナンス等の作業性が悪い。   In such a coupling structure with engagement claws, it is preferable that the coupling claws are hard to come off from the hole and the coupling strength is strong in consideration of the operation of the airbag device. On the other hand, for example, when considering removing the airbag device for vehicle maintenance or the like, workability such as maintenance is poor if the engagement claw is difficult to come out of the hole.

本発明は、上記事実を考慮して、エアバッグ装置の非作動状態と作動状態とでエアバッグ装置とこのエアバッグ装置が取り付けられる部位との結合強度を異ならせることができるエアバッグ装置組付構造及び部材同士の結合強度を異ならせることができる部材組付構造を得ることが目的である。   In consideration of the above facts, the present invention is an assembly of an airbag device that can vary the coupling strength between the airbag device and a portion to which the airbag device is attached depending on whether the airbag device is in an inoperative state or an activated state. It is an object to obtain a member assembly structure in which the structure and the bonding strength between members can be made different.

請求項１に記載の本発明に係るエアバッグ装置組付構造は、車両の被取付部及び前記被取付部に組み付けられる前記エアバッグ装置の取付部の何れかの一方に形成された孔部に対し、前記何れかの他方に形成された係合部を係合させ、前記孔部に対する前記係合部の係合方向とは反対方向を向く前記係合部の所定部位と、前記孔部の周囲で前記何れかの一方とを対向させることで前記被取付部に前記取付部を組み付けるエアバッグ装置組付構造であって、前記エアバッグ装置が作動していない非作動状態に比べて前記エアバッグ装置が作動した作動状態で前記係合部の前記所定部位と、前記孔部の周囲で前記何れかの一方との対向面積を増加させることを特徴としている。   According to a first aspect of the present invention, there is provided an air bag device assembly structure in a hole formed in one of a mounting portion of a vehicle and a mounting portion of the airbag device assembled to the mounted portion. On the other hand, the engagement portion formed on any one of the other is engaged, and a predetermined portion of the engagement portion facing in a direction opposite to the engagement direction of the engagement portion with respect to the hole portion, and the hole portion An airbag device assembly structure in which the attachment portion is assembled to the attachment portion by facing one of the surroundings in the periphery, and the air bag device is compared with a non-operating state in which the airbag device is not activated. In the operation state in which the bag device is activated, the facing area between the predetermined portion of the engaging portion and any one of the ones around the hole portion is increased.

請求項１に記載の本発明に係るエアバッグ装置組付構造では、車両の被取付部及びエアバッグ装置の取付部の何れかの一方に形成された孔部に対し、何れかの他方に形成された係合部を係合させると、この孔部に対する係合部の係合方向とは反対方向を向く係合部の所定部位と、孔部の周囲で前記何れか一方（すなわち、車両の被取付部及びエアバッグ装置の取付部のうち、孔部が形成された方）とが対向する。これにより、孔部から係合部が抜け出ようとすると、孔部の周囲が係合部に当接し、孔部から係合部が抜け出ることを規制する。これにより、車両の被取付部とエアバッグ装置の取付部とが結合される。   In the airbag apparatus assembly structure according to the first aspect of the present invention, the air bag apparatus is formed on one of the holes formed in one of the mounted part of the vehicle and the mounting part of the airbag apparatus. When the engaged portion is engaged, a predetermined portion of the engaging portion that faces in a direction opposite to the engaging direction of the engaging portion with respect to the hole portion and either one of the above-mentioned portions (that is, the vehicle) Of the attachment portion and the attachment portion of the airbag apparatus, the one in which the hole is formed is opposed to the attachment portion. Accordingly, when the engaging portion is about to come out from the hole portion, the periphery of the hole portion comes into contact with the engaging portion, and the engagement portion is prevented from coming out from the hole portion. Thereby, the to-be-attached part of a vehicle and the attaching part of an airbag apparatus are couple | bonded.

一方、エアバッグ装置が作動すると孔部に対する係合部の係合方向とは反対方向に沿った係合部と孔部の周囲との対向面積がエアバッグ装置の作動前に比べて増加する。このため、孔部から係合部が抜け出ようとして孔部の周囲に係合部に当接した際の当接面積がエアバッグ装置の作動前に比べて大きくなり、エアバッグ装置の作動前に比べて孔部から係合部が抜け難くなる。   On the other hand, when the airbag device is activated, the facing area between the engagement portion and the periphery of the hole along the direction opposite to the engagement direction of the engagement portion with respect to the hole portion is increased as compared to before the operation of the airbag device. For this reason, the contact area when the engaging part comes out of the hole and comes into contact with the engaging part around the hole is larger than before the operation of the airbag device, and before the operation of the airbag device. In comparison, it is difficult for the engaging portion to come out of the hole portion.

すなわち、本発明に係るエアバッグ装置組付構造では、エアバッグ装置の作動前に比べてエアバッグ装置が作動した際に車両の被取付部とエアバッグ装置の取付部との結合強度を強くできるため、相対的にエアバッグ装置の作動前の状態で車両の被取付部とエアバッグ装置の取付部との結合強度を弱くでき、メンテナンス等でエアバッグ装置の取付部を車両の被取付部から取り外す際の作業性を向上できる。   That is, in the airbag device assembly structure according to the present invention, when the airbag device is activated, the coupling strength between the mounted portion of the vehicle and the attachment portion of the airbag device can be increased compared to before the airbag device is activated. Therefore, the coupling strength between the mounting portion of the vehicle and the mounting portion of the airbag device can be weakened relatively before the operation of the airbag device, and the mounting portion of the airbag device can be removed from the mounting portion of the vehicle for maintenance or the like. The workability when removing can be improved.

なお、エアバッグ装置は、その設置箇所に応じて様々な態様があるが、本発明が適用されるエアバッグ装置は、その何れであってもよく、エアバッグ装置の設置箇所等や構造等に限定されるものではない。   The airbag device has various modes depending on the installation location. However, the airbag device to which the present invention is applied may be any one of them, and the installation location or structure of the airbag device may be used. It is not limited.

また、本発明において、車両の被取付部は及びエアバッグ装置の取付部は、車両とエアバッグ装置との結合部分を構成するのであれば、その名称や構造等に限定されるものではない。   In the present invention, the attachment portion of the vehicle and the attachment portion of the airbag device are not limited to their names and structures as long as they constitute a coupling portion between the vehicle and the airbag device.

さらに、本発明において、係合部は孔部に係合した状態で孔部の周囲に対向することで孔部からの抜け止めが成される構成であればよく、その名称や構造等に限定されるものではない。   Furthermore, in the present invention, the engaging portion may be configured so that the engaging portion is prevented from coming off from the hole portion by facing the periphery of the hole portion while being engaged with the hole portion, and is limited to its name, structure, and the like. Is not to be done.

また、本発明では、エアバッグ装置が作動する前に比べてエアバッグ装置が作動した状態で係合部の所定部位と、孔部の周囲との対向面積が増加する構成であるが、これは、エアバッグ装置が作動することで変位したり、変形したりするような部位に孔部を形成することで、エアバッグ装置が作動した際に係合部の所定部位と孔部の周囲との対向面積が増加する構成であってもよいし、エアバッグ装置が作動した際に、駆動手段の駆動力等で孔部が形成された部位や、係合部が形成された部位を積極的に変位させたり、変形させたりすることで係合部の所定部位と孔部の周囲との対向面積が増加する構成であってもよい。   Further, in the present invention, compared to before the airbag device is activated, the opposed area between the predetermined portion of the engaging portion and the periphery of the hole portion is increased in a state where the airbag device is activated. By forming a hole in a portion that is displaced or deformed by the operation of the airbag device, when the airbag device is operated, the predetermined portion of the engaging portion and the periphery of the hole The configuration may be such that the opposing area increases, and when the airbag device is activated, the part where the hole is formed by the driving force of the driving means or the part where the engaging part is formed is positively The structure which the opposing area of the predetermined site | part of an engaging part and the circumference | surroundings of a hole increases by displacing or changing may be sufficient.

請求項２に記載の本発明に係るエアバッグ装置組付構造は、請求項１に記載の本発明において、前記取付部を含めて構成されるモジュールケースと、前記モジュールケースの内側に収容されて内部に供給されるガス圧で膨張展開する袋体と、を含めて前記エアバッグ装置を構成すると共に、膨張する前記袋体の圧力による前記取付部の前記被取付部に対する変位で前記係合部の前記所定部位と、前記孔部の周囲で前記何れかの一方との対向面積が増加する、ことを特徴としている。   According to a second aspect of the present invention, there is provided an air bag device assembly structure according to the first aspect of the present invention, wherein in the first aspect of the present invention, the module case is configured to include the mounting portion, and is accommodated inside the module case. And a bag body that is inflated and deployed by a gas pressure supplied to the inside, and the engagement portion is configured by displacement of the attachment portion with respect to the attached portion due to the pressure of the bag body that is inflated. The area where the predetermined portion of the surface and the one of the ones around the hole portion increases is increased.

請求項２に記載の本発明に係るエアバッグ装置組付構造では、エアバッグ装置のモジュールケース内に収容された袋体の内部にガスが供給され、これにより、袋体が膨張すると、袋体がモジュールケースを内側から押圧し、モジュールケースを変位（変形）させる。これにより、車両の被取付部に取り付けられたモジュールケースの取付部が被取付部に対して変位する。   In the airbag apparatus assembly structure according to the second aspect of the present invention, when the gas is supplied into the bag body accommodated in the module case of the airbag apparatus, and the bag body is inflated, the bag body Presses the module case from the inside to displace (deform) the module case. Thereby, the attachment part of the module case attached to the attachment part of the vehicle is displaced with respect to the attachment part.

この車両の被取付部に対するモジュールケースの取付部の変位が生じると、孔部に係合する際の係合部の係合方向とは反対方向に沿った係合部の所定部位と、孔部の周囲との対向面積が増加する。これにより、エアバッグ装置の作動前に比べてエアバッグ装置が作動した際に車両の被取付部とエアバッグ装置の取付部との結合強度を強くできる。   When the displacement of the mounting portion of the module case with respect to the mounted portion of the vehicle occurs, the predetermined portion of the engaging portion along the direction opposite to the engaging direction of the engaging portion when engaging with the hole portion, and the hole portion The area opposite to the surrounding area increases. Thereby, when the airbag apparatus operates, compared with before the operation of the airbag apparatus, the coupling strength between the mounted part of the vehicle and the mounting part of the airbag apparatus can be increased.

請求項３に記載の本発明に係るエアバッグ装置組付構造は、請求項２に記載の本発明において、前記袋体の圧力で前記取付部が前記被取付部に対して変位した際の前記孔部内における前記係合部の変位方向へ向けて、前記変位方向に対して直交した前記孔部に開口内幅寸法を小さく設定することを特徴としている。   According to a third aspect of the present invention, the airbag device assembly structure according to the second aspect of the present invention is the invention according to the second aspect, wherein the attachment portion is displaced with respect to the attachment portion by the pressure of the bag body. An opening inner width dimension is set small in the hole perpendicular to the displacement direction toward the displacement direction of the engaging portion in the hole.

請求項３に記載の本発明に係るエアバッグ装置組付構造では、膨張する袋体からの押圧力で生じたモジュールケースの変位（変形）に伴う孔部内での係合部の変位方向へ向けて、この変位方向に対して直交した孔部の開口内幅寸法が小さくなる。したがって、上記のようにモジュールケースが変位（変形）して係合部が孔部内で変位すると、孔部に係合する際の係合部の係合方向とは反対方向に沿った係合部の所定部位と、孔部の周囲との対向面積が増加する。これにより、エアバッグ装置の作動前に比べてエアバッグ装置が作動した際に車両の被取付部とエアバッグ装置の取付部との結合強度を強くできる。   In the airbag device assembly structure according to the third aspect of the present invention, the engagement portion is directed toward the displacement direction in the hole portion due to the displacement (deformation) of the module case caused by the pressing force from the inflating bag body. Thus, the opening inner width dimension of the hole perpendicular to the displacement direction is reduced. Therefore, when the module case is displaced (deformed) as described above and the engagement portion is displaced in the hole portion, the engagement portion along the direction opposite to the engagement direction of the engagement portion when engaging with the hole portion. This increases the facing area between the predetermined portion and the periphery of the hole. Thereby, when the airbag apparatus operates, compared with before the operation of the airbag apparatus, the coupling strength between the mounted part of the vehicle and the mounting part of the airbag apparatus can be increased.

請求項４に記載の本発明に係る部材組付構造は、組付部材が組み付けられる被組付部材及び前記組付部材の何れかの一方に形成された孔部に対し、前記何れかの他方に形成された係合部を係合させ、前記孔部に対する前記係合部の係合方向とは反対方向を向く前記係合部の所定部位と、前記孔部の周囲で前記何れかの一方とを対向させることで前記被組付部材に前記組付部材を組み付ける部材組付構造であって、前記組付部材又は前記被組付部材を含めて構成された所定の装置が作動した際の前記被組付部材に対する前記組付部材の相対変位による前記孔部内における前記係合部の変位方向へ向けて、前記変位方向に対して直交した前記孔部の開口内幅寸法を小さく設定することを特徴としている。   According to a fourth aspect of the present invention, there is provided the member assembling structure according to the present invention, wherein either one of the other member is attached to a hole formed in one of the member to be assembled and the member to be assembled. A predetermined portion of the engagement portion that is directed in a direction opposite to the engagement direction of the engagement portion with respect to the hole portion, and one of the ones around the hole portion. Is a member assembly structure for assembling the assembly member to the assembly member, and when the predetermined device configured including the assembly member or the assembly member is operated. The opening width dimension of the hole perpendicular to the displacement direction is set smaller toward the displacement direction of the engagement portion in the hole due to relative displacement of the assembly member with respect to the assembly member. It is characterized by.

請求項４に記載の本発明に係る部材組付構造では、組付部材及び被組付部材の何れかの一方に形成された孔部に対し、何れかの他方に形成された係合部を係合させると、この孔部に対する係合部の係合方向とは反対方向を向く係合部の所定部位と、孔部の周囲で前記何れか一方（すなわち、組付部材及び被組付部材のうち、孔部が形成された方）とが対向する。これにより、孔部から係合部が抜け出ようとすると、孔部の周囲が係合部に当接し、孔部から係合部が抜け出ることを規制する。これにより、被組付部材と組付部材とが結合される。   In the member assembly structure according to the fourth aspect of the present invention, the engagement portion formed on either one of the hole portion formed on one of the assembly member and the member to be assembled is provided. When engaged, a predetermined portion of the engaging portion that faces in a direction opposite to the engaging direction of the engaging portion with respect to the hole portion, and either one of the aforementioned portions around the hole portion (that is, the assembling member and the assembled member) Among them, the one in which the hole is formed is opposed. Accordingly, when the engaging portion is about to come out from the hole portion, the periphery of the hole portion comes into contact with the engaging portion, and the engagement portion is prevented from coming out from the hole portion. Thereby, a to-be-assembled member and an assembly member are couple | bonded.

一方、組付部材又は被組付部材を含めて構成された所定の装置が作動すると、被組付部材に対して組付部材が相対変位し、これに伴い、孔部内で係合部が変位する。ここで、この係合部の変位方向に対して直交した向きの孔部の開口内幅寸法は、この係合部の変位方向へ向けて小さくなる。このため、係合部が変位する前に比べて係合部が変位した後では、孔部に係合部が係合する際の係合部の係合方向とは反対方向に沿った係合部の所定部位と、孔部の周囲との対向面積が増加する。上記所定の装置が作動した状態では、孔部から係合部が抜け出ようとして孔部の周囲に係合部に当接した際の当接面積が大きくなり、孔部から係合部が抜け難くなる。   On the other hand, when a predetermined device configured including the assembled member or the assembled member is operated, the assembled member is relatively displaced with respect to the assembled member, and accordingly, the engaging portion is displaced in the hole. To do. Here, the opening width dimension of the hole in the direction orthogonal to the displacement direction of the engagement portion decreases toward the displacement direction of the engagement portion. For this reason, after the engagement portion is displaced compared to before the engagement portion is displaced, the engagement is performed in a direction opposite to the engagement direction of the engagement portion when the engagement portion is engaged with the hole. The facing area between the predetermined part of the part and the periphery of the hole is increased.

また、インフレータ１４は図示しない制御手段としてのエアバッグＥＣＵを介して検出手段としての車両の加速度センサに接続されており、加速度センサが車両の急減速状態を検出すると、エアバッグＥＣＵがインフレータ１４を作動させる構成になっている。また、モジュールケース１２の内側には袋体１６が折り畳み状態で収容されている。袋体１６はその内側に上記のインフレータ１４を収容している。インフレータ１４の内部でガス発生剤が燃焼することで発生し、更に、インフレータ１４の外部へ放出されたガスは、袋体１６の内部に供給されて袋体１６の内圧を急上昇させる。   The inflator 14 is connected to an acceleration sensor of a vehicle as a detection means via an airbag ECU as a control means (not shown). When the acceleration sensor detects a sudden deceleration state of the vehicle, the airbag ECU causes the inflator 14 to It is configured to operate. Moreover, the bag body 16 is accommodated in the folded state inside the module case 12. The bag body 16 accommodates the inflator 14 inside thereof. Gas generated when the gas generating agent burns inside the inflator 14, and the gas released to the outside of the inflator 14 is supplied to the inside of the bag body 16 to rapidly increase the internal pressure of the bag body 16.

一方、略車両後方を向いたモジュールケース１２の開口端には組付部材としてのエアバッグドア１８が設けられている。エアバッグドア１８は枠部２０を備えている。この枠部２０に対応してモジュールケース１２の開口端からは上方及び下方へ向けてフランジ状の固定片２２が延出されている。これらの固定片２２は枠部２０に機械的に連結され、これにより、エアバッグドア１８がモジュールケース１２に一体的に取り付けられる構成になっている。枠部２０のモジュールケース１２とは反対側の開口端側にはドア部２４が設けられている。   On the other hand, an airbag door 18 as an assembly member is provided at the open end of the module case 12 facing substantially rearward of the vehicle. The airbag door 18 includes a frame portion 20. A flange-shaped fixing piece 22 extends upward and downward from the open end of the module case 12 corresponding to the frame portion 20. These fixing pieces 22 are mechanically connected to the frame portion 20, whereby the airbag door 18 is integrally attached to the module case 12. A door portion 24 is provided on the opening end side of the frame portion 20 opposite to the module case 12.

ドア部２４は矩形平板状に形成されており、枠部２０のモジュールケース１２とは反対側で枠部２０を閉止している。ドア部２４の外周部と枠部２０の内周部との間には脆弱部２６が形成されている。脆弱部２６はドア部２４や枠部２０よりも薄肉に形成され、ドア部２４や枠部２０よりも機械的強度が弱い。また、略車両上下方向に沿ったドア部２４の略中央部には脆弱部２７が形成されている。脆弱部２７もまた脆弱部２６と同様の構成で、ドア部２４の他の部分や枠部２０よりも薄肉とされ、ドア部２４の他の部分や枠部２０よりも機械的強度が弱い。   The door portion 24 is formed in a rectangular flat plate shape, and closes the frame portion 20 on the opposite side of the frame portion 20 from the module case 12. A fragile portion 26 is formed between the outer peripheral portion of the door portion 24 and the inner peripheral portion of the frame portion 20. The fragile portion 26 is formed thinner than the door portion 24 and the frame portion 20, and has a lower mechanical strength than the door portion 24 and the frame portion 20. Moreover, the weak part 27 is formed in the approximate center part of the door part 24 along the substantially vehicle up-down direction. The fragile portion 27 is also configured in the same manner as the fragile portion 26, and is thinner than other portions of the door portion 24 and the frame portion 20, and has a lower mechanical strength than the other portions of the door portion 24 and the frame portion 20.

ドア部２４のモジュールケース１２側から所定の大きさ以上の圧力がドア部２４に作用すると脆弱部２６や脆弱部２７が先ず破断又は屈曲する。これにより、図４に示されるように、脆弱部２７よりも上側ではドア部２４が上方へ回動し、脆弱部２７よりも下側ではドア部２４が上方へ回動するようにドア部２４が展開して、モジュールケース１２の開口端が開放される構成になっている。   When pressure of a predetermined magnitude or more is applied to the door portion 24 from the module case 12 side of the door portion 24, the fragile portion 26 and the fragile portion 27 are first broken or bent. As a result, as shown in FIG. 4, the door portion 24 is rotated upward above the fragile portion 27, and the door portion 24 is rotated upward below the fragile portion 27. Is expanded so that the open end of the module case 12 is opened.

図２及び図３に示されるように、エアバッグドア１８が取り付けられたモジュールケース１２は車両の運転席や助手席の前方側に設けられた被取付部又は被組付部材としてのインスツルメントパネル２８の裏面側に配置される。インスツルメントパネル２８にはドア部２４に対応した矩形の開口部３０が形成されており、図３に示されるように、この開口部３０の内側にドア部２４が位置する。   As shown in FIGS. 2 and 3, the module case 12 to which the airbag door 18 is attached is an instrument as an attached portion or attached member provided in front of the driver's seat or passenger seat of the vehicle. It is arranged on the back side of the panel 28. A rectangular opening 30 corresponding to the door portion 24 is formed in the instrument panel 28, and the door portion 24 is located inside the opening 30 as shown in FIG. 3.

一方、図２及び図３に示されるように、枠部２０の上端には取付部としての取付片３２が形成されており、枠部２０の下端には取付部としての取付片３４が形成されている。取付片３２、３４の各々は枠部２０の開口方向に対して傾斜した方向に（枠部２０の外方）へ延出されている。このように枠部２０から延出された取付片３２、３４の各々は適宜に屈曲し、その先端側はインスツルメントパネル２８の裏面側でインスツルメントパネル２８に対して略平行となるように形成されている。取付片３２の先端側における略車両左右方向略中央には孔部としての取付孔３６が形成されている。図１及び図５（Ａ）、（Ｂ）に示されるように、取付孔３６は略長方形状の幅広部３８を備えている。   On the other hand, as shown in FIGS. 2 and 3, an attachment piece 32 as an attachment portion is formed at the upper end of the frame portion 20, and an attachment piece 34 as an attachment portion is formed at the lower end of the frame portion 20. ing. Each of the attachment pieces 32, 34 extends in the direction inclined with respect to the opening direction of the frame portion 20 (outward of the frame portion 20). In this way, each of the attachment pieces 32 and 34 extending from the frame portion 20 is appropriately bent, and the front end side thereof is substantially parallel to the instrument panel 28 on the back surface side of the instrument panel 28. Is formed. An attachment hole 36 as a hole is formed in the approximate center in the vehicle left-right direction on the distal end side of the attachment piece 32. As shown in FIGS. 1, 5 </ b> A, and 5 </ b> B, the attachment hole 36 includes a substantially rectangular wide portion 38.

この幅広部３８の下端からは誘導部及び幅狭部を構成するテーパ部４０が連続して形成されている。テーパ部４０は上端では略車両左右方向に沿った開口内幅寸法が幅広部３８の開口内幅寸法と同じであるが、下方、すなわち、枠部２０の側へ向けて略車両左右方向に沿った開口内幅寸法が漸次小さくなるテーパ状に形成されている。   From the lower end of this wide part 38, the taper part 40 which comprises a guidance | induction part and a narrow part is formed continuously. In the upper end of the tapered portion 40, the inner width dimension of the opening along the substantially left-right direction of the vehicle is the same as the inner width dimension of the opening of the wide portion 38. Further, the inner width dimension of the opening is tapered to be gradually reduced.

図１に示されるように、この取付孔３６に対応してインスツルメントパネル２８には係合部としてのクリップ４２が形成されている。クリップ４２は開口部３０の上側でインスツルメントパネル２８の裏面から突出形成されている。クリップ４２は軸部４４を備えている。軸部４４は概ね略車両左右方向を向く横幅寸法がテーパ部４０の下端部、すなわち、テーパ部４０において最も開口内幅が狭い部分における開口内幅寸法以下に設定されると共に、取付片３２からの突出方向及び横幅方向の双方に対して直交した向きの縦幅寸法が、略車両上下方向に沿った幅広部３８の開口幅寸法以下に設定された角棒状に形成され、その基端部はインスツルメントパネル２８に繋がっている。   As shown in FIG. 1, a clip 42 as an engaging portion is formed on the instrument panel 28 corresponding to the mounting hole 36. The clip 42 is formed to protrude from the back surface of the instrument panel 28 above the opening 30. The clip 42 includes a shaft portion 44. The shaft portion 44 is set to have a width dimension that is substantially in the left-right direction of the vehicle substantially equal to or smaller than the inner width dimension of the opening in the lower end portion of the tapered portion 40, that is, the narrowest opening width in the tapered portion 40. The vertical width dimension in the direction orthogonal to both the projecting direction and the horizontal width direction is formed in a square bar shape set to be equal to or smaller than the opening width dimension of the wide portion 38 along the vertical direction of the vehicle. It is connected to the instrument panel 28.

軸部４４の先端には爪部４６が連続して形成されている。爪部４６の縦幅寸法は軸部４４と同じであるが、爪部４６の基端部（すなわち、軸部４４側の端部）における爪部４６の横幅寸法はテーパ部４０の開口内幅寸法よりも大きく、しかも、横幅方向に沿って略同寸法だけ軸部４４よりも外側へ突出している。   A claw portion 46 is formed continuously at the tip of the shaft portion 44. The vertical width dimension of the claw part 46 is the same as that of the shaft part 44, but the lateral width dimension of the claw part 46 at the base end part (that is, the end part on the shaft part 44 side) of the claw part 46 is the opening inner width of the taper part 40. It is larger than the dimension and projects outward from the shaft portion 44 by substantially the same dimension along the lateral width direction.

但し、爪部４６は軸部４４とは反対側へ向けて横幅寸法が漸次小さくなるテーパ状に形成されており、その先端部における横幅寸法は、少なくとも、テーパ部４０の開口内幅寸法よりも充分に小さい。軸部４４の側方でインスツルメントパネル２８の側を向く爪部４６の基端部の面は干渉面４８とされている。干渉面４８は、軸部４４が取付孔３６を貫通して爪部４６が取付片３２の裏面側に位置すると、干渉面４８が取付孔３６の周囲で取付片３２と対向する。以上の構成のクリップ４２は横幅の向きに沿った略中央に溝部５０が形成されている。溝部５０はクリップ４２の先端部にて開口している。このため、クリップ４２は先端側で横幅寸法が小さくなるように弾性変形が可能で、このように弾性変形させることでクリップ４２は取付孔３６を貫通できる。   However, the claw portion 46 is formed in a tapered shape whose lateral width dimension gradually decreases toward the opposite side of the shaft portion 44, and the lateral width dimension at the tip portion is at least larger than the in-opening width dimension of the tapered portion 40. Small enough. A surface of the base end portion of the claw portion 46 facing the instrument panel 28 on the side of the shaft portion 44 is an interference surface 48. When the shaft portion 44 passes through the attachment hole 36 and the claw portion 46 is located on the back side of the attachment piece 32, the interference surface 48 faces the attachment piece 32 around the attachment hole 36. The clip 42 configured as described above has a groove 50 formed substantially at the center along the width direction. The groove 50 opens at the tip of the clip 42. For this reason, the clip 42 can be elastically deformed so that the lateral width dimension is reduced on the distal end side, and the clip 42 can penetrate the attachment hole 36 by being elastically deformed in this way.

一方、図２及び図３に示されるように、取付片３４には取付孔５２が形成されている。取付孔５２は幅広部３８とテーパ部４０の位置や向きが取付孔３６とは上下反対の構造となっている。取付片３２には取付孔３６に対応したクリップ４２とは別に取付孔５２に対応したクリップ４２が形成されており、これらの一対のクリップ４２が取付孔３６と取付孔５２の双方を貫通することでニーエアバッグ装置１０が取付片３２に取り付けられる。ここで、一対のクリップ４２は、取付孔３６、５２の各幅広部３８側で取付孔３６、５２を貫通するように取付片３２における形成位置が設定されている。   On the other hand, as shown in FIGS. 2 and 3, a mounting hole 52 is formed in the mounting piece 34. The attachment hole 52 has a structure in which the positions and orientations of the wide portion 38 and the tapered portion 40 are opposite to those of the attachment hole 36. A clip 42 corresponding to the mounting hole 52 is formed in the mounting piece 32 in addition to the clip 42 corresponding to the mounting hole 36, and the pair of clips 42 penetrates both the mounting hole 36 and the mounting hole 52. Then, the knee airbag device 10 is attached to the attachment piece 32. Here, the formation position in the attachment piece 32 is set so that a pair of clip 42 may penetrate the attachment holes 36 and 52 in each wide part 38 side of the attachment holes 36 and 52.

＜第１の実施の形態の作用、効果＞
次に本実施の形態の作用並びに効果について説明する。図５の（Ｂ）に示されるように、一対のクリップ４２が取付孔３６、５２の幅広部３８を貫通してニーエアバッグ装置１０がインスツルメントパネル２８に取り付けられた状態では、クリップ４２の干渉面４８が取付片３２と対向する。このため、この状態でモジュールケース１２が略車両前方側へ移動しようとすると、取付片３２、３４が干渉面４８に当接する。これにより、モジュールケース１２の略車両前方側への移動が規制され、取付孔３６、５２からクリップ４２が抜け出ることが規制され、エアバッグドア１８と取付片３２との機械的な連結状態が維持される。 <Operation and Effect of First Embodiment>
Next, the operation and effect of the present embodiment will be described. As shown in FIG. 5B, in a state where the pair of clips 42 penetrates the wide portion 38 of the mounting holes 36 and 52 and the knee airbag device 10 is attached to the instrument panel 28, the clips 42. The interference surface 48 faces the mounting piece 32. For this reason, when the module case 12 is about to move to the front side of the vehicle in this state, the mounting pieces 32 and 34 come into contact with the interference surface 48. As a result, the movement of the module case 12 substantially to the front side of the vehicle is restricted, the clip 42 is restricted from coming out of the attachment holes 36 and 52, and the mechanical connection between the airbag door 18 and the attachment piece 32 is maintained. Is done.

一方、車両が急減速状態になり、エアバッグＥＣＵがインフレータ１４を作動させ、これにより、インフレータ１４から瞬時に大量のガスが発生すると、このガスの圧力によって袋体１６が膨張する。膨張した袋体１６はエアバッグドア１８を押圧して、脆弱部２７を破断させると共に、脆弱部２６を軸にドア部２４を展開する。これにより、膨張した袋体１６は開口部３０から車両室内側の乗員の膝付近で展開される。   On the other hand, when the vehicle suddenly decelerates and the airbag ECU activates the inflator 14, and a large amount of gas is instantaneously generated from the inflator 14, the bag body 16 is expanded by the pressure of this gas. The inflated bag body 16 presses the airbag door 18 to break the fragile portion 27 and develops the door portion 24 around the fragile portion 26. As a result, the inflated bag body 16 is deployed from the opening 30 in the vicinity of the passenger's knee on the vehicle interior side.

また、このように袋体１６が膨張すると、図４に示されるように、袋体１６はモジュールケース１２を内側から押圧する。この押圧力により、モジュールケース１２はその開口方向に対して略直交したモジュールケース１２の外方へ変形する。この変形により、取付片３２は略上方へ変位し、これにより、図５の（Ｂ）に示されるように、幅広部３８にて取付孔３６を貫通していたクリップ４２の軸部４４は、テーパ部４０側へ移動する。また、図示は省略するが、上記のようなモジュールケース１２の変形に伴い、取付片３４は略下方へ変位する。このため、取付孔５２の幅広部３８を貫通していたクリップ４２の軸部４４は、取付孔５２のテーパ部４０側へ移動する。   Further, when the bag body 16 is inflated in this way, as shown in FIG. 4, the bag body 16 presses the module case 12 from the inside. By this pressing force, the module case 12 is deformed outwardly of the module case 12 substantially orthogonal to the opening direction. Due to this deformation, the attachment piece 32 is displaced substantially upward, and as shown in FIG. 5B, the shaft portion 44 of the clip 42 that has penetrated the attachment hole 36 in the wide portion 38 is It moves to the taper part 40 side. Although illustration is omitted, the attachment piece 34 is displaced substantially downward along with the deformation of the module case 12 as described above. For this reason, the shaft portion 44 of the clip 42 that has passed through the wide portion 38 of the attachment hole 52 moves to the tapered portion 40 side of the attachment hole 52.

ここで、取付孔３６、５２のテーパ部４０はテーパ状に形成され、幅広部３８とは反対側ではテーパ部４０の開口内幅寸法は幅広部３８の開口内幅寸法よりも狭い。このため、軸部４４がテーパ部４０を貫通している状態での取付片３２と干渉面４８との対向面積Ｓ２（図５（Ｂ）参照）は、軸部４４が幅広部３８を貫通している状態での取付片３２と干渉面４８との対向面積Ｓ１（図５（Ａ）参照）に比べて大きくなる。このため、この状態でクリップ４２が取付孔３６、５２から抜け出ようとしても、取付片３２、３４と干渉面４８との当接面積が広くなっているため、より一層抜け難く、エアバッグドア１８とインスツルメントパネル２８との結合強度が高くなる。   Here, the taper portion 40 of the attachment holes 36 and 52 is formed in a taper shape, and the opening inner width dimension of the taper portion 40 is narrower than the opening inner width dimension of the wide portion 38 on the side opposite to the wide portion 38. Therefore, the facing area S2 (see FIG. 5B) between the mounting piece 32 and the interference surface 48 in a state where the shaft portion 44 penetrates the taper portion 40, the shaft portion 44 penetrates the wide portion 38. This is larger than the facing area S1 (see FIG. 5A) between the mounting piece 32 and the interference surface 48 in a state where the mounting piece 32 is in the closed state. For this reason, even if the clip 42 tries to come out of the attachment holes 36 and 52 in this state, the contact area between the attachment pieces 32 and 34 and the interference surface 48 is widened, so that it is further difficult to come out. And the bonding strength between the instrument panel 28 and the instrument panel 28 are increased.

また、この点について換言すると、上記のようにモジュールケース１２が変形していない状態では、幅広部３８を軸部４４が貫通していることで、取付片３２と干渉面４８との対向面積が小さい。このため、通常時においてはクリップ４２を取付孔３６、５２から抜け出させることが容易である。このため、車両のメンテナンス等でニーエアバッグ装置１０を取り外す際の作業を容易に行なうことができる。   In other words, in this state, when the module case 12 is not deformed as described above, the shaft portion 44 passes through the wide portion 38, so that the facing area between the mounting piece 32 and the interference surface 48 is increased. small. For this reason, it is easy to let the clip 42 come out of the attachment holes 36 and 52 in normal times. For this reason, the operation | work at the time of removing the knee airbag apparatus 10 by a vehicle maintenance etc. can be performed easily.

なお、本実施の形態では、本発明を乗員の膝に対応して設けられるニーエアバッグ装置１０の取り付けに適用した構成であったが、本発明がニーエアバッグ装置１０に限定されるものではなく、乗員の他の部位に対応したエアバッグ装置の取り付けに本発明を適用してもよい。   In the present embodiment, the present invention is applied to the mounting of the knee airbag device 10 provided corresponding to the occupant's knee, but the present invention is not limited to the knee airbag device 10. Instead, the present invention may be applied to attachment of an airbag device corresponding to another part of the occupant.
