図１、２に示されるように、本発明の実施形態に係るグラブドア付けニーエアバッグ装置１０はグラブドア１２と、アウタ部材１４と、ボックス部材１６と、エアバッグモジュール１８を備えている。また、本実施形態ではグラブドア１２とボックス部材１６が一体に成形されることで所謂グラブボックスを構成している。   As shown in FIGS. 1 and 2, a knee airbag device 10 with a grab door according to an embodiment of the present invention includes a grab door 12, an outer member 14, a box member 16, and an airbag module 18. In the present embodiment, the grab door 12 and the box member 16 are integrally formed to form a so-called grab box.

アウタ部材１４は、例えば樹脂で成形されており、車両前側部を構成する前壁１４Ａと、前壁１４Ａの両側部からそれぞれ車両後方側へ延在する側壁１４Ｂと、左右の側壁１４Ｂをそれぞれ車両上側部と車両下側部とでそれぞれ車幅方向に接続する上壁１４Ｃ、下壁１４Ｄによって構成されている。ここで、アウタ部材１４は図示しない固定手段によってインストルメントパネル２６に固定されており、車両後方側（乗員側）に開口するように配置されている。   The outer member 14 is formed of, for example, resin, and includes a front wall 14A constituting the vehicle front side portion, a side wall 14B extending from the both sides of the front wall 14A to the vehicle rear side, and a left and right side wall 14B. The upper wall portion 14C and the lower wall portion 14D are respectively connected to the upper side portion and the vehicle lower side portion in the vehicle width direction. Here, the outer member 14 is fixed to the instrument panel 26 by fixing means (not shown), and is arranged so as to open to the vehicle rear side (occupant side).

また、アウタ部材１４の内側にはボックス部材１６が配置されている。ボックス部材１６は例えば樹脂で成形されており、グラブドア１２と一体に成形されている。ボックス部材１６は車両前側部を構成する前壁１６Ａと、前壁１６Ａの車幅方向両側部からそれぞれ車両後方側へ延在すると共にグラブドア１２に接続されて側面を構成する外壁１６Ｂとを備えている。また、左右の外壁１６Ｂは車両下部側において底面を構成する下壁１６Ｃで車幅方向に接続されており、車両上側に開口した収納空間２２を備えている。   A box member 16 is disposed inside the outer member 14. The box member 16 is formed of resin, for example, and is formed integrally with the grab door 12. The box member 16 includes a front wall 16A that constitutes a vehicle front side portion, and an outer wall 16B that extends from both sides in the vehicle width direction of the front wall 16A to the vehicle rear side and is connected to the grab door 12 to constitute a side surface. Yes. The left and right outer walls 16B are connected to each other in the vehicle width direction by a lower wall 16C that forms a bottom surface on the vehicle lower side, and include a storage space 22 that opens on the vehicle upper side.

なお、ボックス部材１６は後述するように車両前後方向にスライド移動可能にアウタ部材１４と連結されている。また、グラブドア１２の車室内側にはグラブドア１２の一部を構成し、車室内側の意匠面を構成するグラブドアパネル３０が設けられている。   As will be described later, the box member 16 is connected to the outer member 14 so as to be slidable in the vehicle longitudinal direction. In addition, a grab door panel 30 that constitutes a part of the grab door 12 and forms a design surface on the vehicle interior side is provided on the vehicle interior side of the grab door 12.

さらに、グラブドア１２には開閉装置２４が設けられている。ここで、乗員が開閉装置２４を操作するとロック（図示せず）が解除されてグラブドア１２と共にボックス部材１６が車両後方側（乗員側）にスライド移動して収納空間２２が車室内に開放される。   Further, the grab door 12 is provided with an opening / closing device 24. Here, when the occupant operates the opening / closing device 24, the lock (not shown) is released, the box member 16 together with the grab door 12 slides to the vehicle rear side (occupant side), and the storage space 22 is opened into the vehicle interior. .

また、グラブドア１２の車両前方側には、ボックス部材１６の下壁１６Ｃの車両下方側にエアバッグモジュール１８が取り付けられている。エアバッグモジュール１８は、衝突を検出又は予知した際に展開するニーエアバッグ２８と、ニーエアバッグ２８にガスを供給するインフレータ（図示せず）と、インフレータを支持して固定するインフレータ支持部材（図示せず）とを含んで構成される。   An airbag module 18 is attached to the front side of the grab door 12 on the vehicle lower side of the lower wall 16C of the box member 16. The airbag module 18 includes a knee airbag 28 that is deployed when a collision is detected or predicted, an inflator (not shown) that supplies gas to the knee airbag 28, and an inflator support member that supports and fixes the inflator ( (Not shown).

また、グラブドア１２の意匠面を構成するグラブドアパネル３０の意匠面の裏面には、車両後方視でエアバッグモジュール１８と重なる位置にティアライン４６が設けられている。ティアライン４６は車両後方視で略「Ｈ」字状に成形され、ニーエアバッグ２８が展開するとニーエアバッグ２８から展開圧を受けて、ティアライン４６から破断することで開口部４４が形成される。   Further, a tear line 46 is provided on the back surface of the design surface of the grab door panel 30 constituting the design surface of the grab door 12 at a position overlapping the airbag module 18 when viewed from the rear of the vehicle. The tear line 46 is formed in a substantially “H” shape when viewed from the rear of the vehicle. When the knee airbag 28 is deployed, the tear line 46 receives deployment pressure from the knee airbag 28 and breaks from the tear line 46 to form an opening 44. The

ここで、図３を用いて本実施形態のアウタ部材１４とボックス部材１６の連結部５０について詳しく説明する。アウタ部材１４には側壁１４Ｂを車幅方向に貫通し、車両前後方向に延在するガイド部２０が設けられている。また、ボックス部材１６の内部には、車幅方向に延在してボックス部材１６の外壁１６Ｂから車幅方向外側に向けて突出する連結部材３２が配置されている。ここで、アウタ部材１４に設けられたガイド部２０を、ボックス部材１６を支持する連結部材３２が摺動することで、ボックス部材１６がアウタ部材１４に対して車両前後方向にスライド移動する。   Here, the connection part 50 of the outer member 14 and the box member 16 of this embodiment is demonstrated in detail using FIG. The outer member 14 is provided with a guide portion 20 that penetrates the side wall 14B in the vehicle width direction and extends in the vehicle front-rear direction. In addition, a connecting member 32 that extends in the vehicle width direction and protrudes from the outer wall 16B of the box member 16 toward the outside in the vehicle width direction is disposed inside the box member 16. Here, the connecting member 32 that supports the box member 16 slides on the guide portion 20 provided in the outer member 14, so that the box member 16 slides in the vehicle front-rear direction with respect to the outer member 14.

また、連結部材３２の車幅方向両端部には係止部材４０が螺合、圧入等により取り付けられている。係止部材４０の車両上下方向の幅は少なくともガイド部２０の車両上下方向の幅より広く構成され、アウタ部材１４の側壁１４Ｂの車幅方向外側でアウタ部材１４の側壁１４Ｂと隣接することで、アウタ部材１４とボックス部材１６の車幅方向の相対移動を規制している。   Further, locking members 40 are attached to both ends of the connecting member 32 in the vehicle width direction by screwing, press-fitting or the like. The width of the locking member 40 in the vehicle vertical direction is configured to be at least wider than the width of the guide portion 20 in the vehicle vertical direction, and is adjacent to the side wall 14B of the outer member 14 outside the side wall 14B of the outer member 14 in the vehicle width direction. The relative movement of the outer member 14 and the box member 16 in the vehicle width direction is restricted.

なお、図２に示すように、本実施形態ではボックス部材１６にリンク機構３４が設けられている。ボックス部材１６が車両後方側（乗員側）にスライド移動すると、リンク機構３４によってボックス部材１６の車両後方側が車両下方側に傾倒し収納空間２２が車両後方側（乗員側）に向かって開口する。   As shown in FIG. 2, in this embodiment, the box member 16 is provided with a link mechanism 34. When the box member 16 slides toward the vehicle rear side (occupant side), the link mechanism 34 tilts the vehicle rear side of the box member 16 toward the vehicle lower side, and the storage space 22 opens toward the vehicle rear side (occupant side).

また、ボックス部材１６はインストルメントパネル２６と左右一対の結合部材３６によって連結されている。結合部材３６は、ボックス部材１６と脱着可能に固定されており、結合部材３６とボックス部材１６との固定が解除されると、ボックス部材１６は連結部材３２を中心に回動して収納空間２２が車両後方側（乗員側）を向いて開口する。この際、グラブドア１２の車両前方側に位置するエアコンフィルタ等（図示せず）が車室内側と連通するようになっている。   The box member 16 is connected to the instrument panel 26 by a pair of left and right coupling members 36. The coupling member 36 is detachably fixed to the box member 16, and when the coupling member 36 and the box member 16 are released from being fixed, the box member 16 rotates about the coupling member 32 to store the storage space 22. Opens toward the vehicle rear side (occupant side). At this time, an air conditioner filter or the like (not shown) located on the vehicle front side of the grab door 12 communicates with the vehicle interior side.

次に、本実施形態の作用及び効果について説明する。   Next, the operation and effect of this embodiment will be described.

上記のように構成されたグラブドア付けニーエアバッグ装置１０のニーエアバッグ２８が衝突を検知又は予知して展開する場合について説明する。   A case will be described in which the knee airbag 28 of the glove door-attached knee airbag device 10 configured as described above detects or predicts a collision and deploys.

衝突が検知又は予知されると、ニーエアバッグ２８は車両後方視でグラブドア１２を覆うように、グラブドア１２と乗員の脚部（膝）４２との間で展開する。   When a collision is detected or predicted, the knee airbag 28 is deployed between the grab door 12 and an occupant's leg (knee) 42 so as to cover the grab door 12 when viewed from the rear of the vehicle.

ここで、グラブドア１２が閉状態の場合、ボックス部材１６は最も車両前方側に位置する。つまり、エアバッグモジュール１８は乗員の脚部４２から最も離れた位置に配置されている。このとき、連結部材３２はガイド部２０の前端部と当接して車両前方側への移動が規制されている。この状態でニーエアバッグ２８が展開されると、ニーエアバッグ２８はグラブドア１２に沿って車両上方側へ展開し、グラブドア１２と乗員の脚部４２との間に展開される（図１の２点鎖線でこれを示す）。そして、ニーエアバッグ２８はグラブドア１２を介してインストルメントパネル２６から反力を得て乗員の膝を保護する。   Here, when the grab door 12 is in the closed state, the box member 16 is positioned closest to the vehicle front side. That is, the airbag module 18 is disposed at a position farthest from the passenger's leg portion 42. At this time, the connecting member 32 is in contact with the front end portion of the guide portion 20, and movement to the vehicle front side is restricted. When the knee airbag 28 is deployed in this state, the knee airbag 28 is deployed on the vehicle upper side along the grab door 12 and is deployed between the grab door 12 and the occupant's legs 42 (see 2 in FIG. 1). This is indicated by the dotted line). The knee airbag 28 obtains a reaction force from the instrument panel 26 through the grab door 12 to protect the passenger's knee.

一方、グラブドア１２が開状態の場合、閉状態の場合と比べてエアバッグモジュール１８は、より乗員の脚部４２に近い位置に配置される。また、グラブドア１２は車両前方側への動きが規制されていない。この状態でニーエアバッグ２８が展開すると、グラブドア１２には車両前方上向きの荷重が加わり（これを図１の矢印Ｆ１で示す）、アウタ部材１４とボックス部材１６の連結部５０に荷重が加わる。   On the other hand, when the grab door 12 is in the open state, the airbag module 18 is disposed closer to the occupant's leg portion 42 than in the closed state. Further, the grab door 12 is not restricted from moving forward of the vehicle. When the knee airbag 28 is deployed in this state, an upward load is applied to the grab door 12 (indicated by an arrow F1 in FIG. 1), and a load is applied to the connecting portion 50 between the outer member 14 and the box member 16.

ここで、本実施形態では連結部材３２がアウタ部材１４の側壁１４Ｂの車幅方向外側まで延在しており、車幅方向全幅に亘ってアウタ部材１４とボックス部材１６が連結されている。このように、アウタ部材１４とボックス部材１６が連結部材３２によって車幅方向に機械的に連結されていることから、ニーエアバッグ２８からグラブドア１２に荷重が加わってもアウタ部材１４とボックス部材１６が連結部５０において外れることなく、グラブドア１２は閉状態の位置まで車両前方側へ安定的にスライド移動する。つまり、ニーエアバッグ２８の反力によってボックス部材１６がアウタ部材１４から脱落することが抑制される。   Here, in this embodiment, the connecting member 32 extends to the outer side in the vehicle width direction of the side wall 14B of the outer member 14, and the outer member 14 and the box member 16 are connected over the entire width in the vehicle width direction. Thus, since the outer member 14 and the box member 16 are mechanically connected in the vehicle width direction by the connecting member 32, the outer member 14 and the box member 16 are applied even when a load is applied from the knee airbag 28 to the grab door 12. The grab door 12 slides stably to the vehicle front side to the closed position without being disconnected at the connecting portion 50. That is, the box member 16 is prevented from dropping from the outer member 14 due to the reaction force of the knee airbag 28.

このように、グラブドア１２が開状態のときにニーエアバッグ２８が展開した場合、アウタ部材１４とボックス部材１６との連結部５０はニーエアバッグ２８からの反力を受ける。その後、連結部材３２が閉状態の位置（図１の二点鎖線で図示する位置）まで車両前方側へスライド移動するので、ニーエアバッグ２８はグラブドア１２、ひいてはインストルメントパネル２６から反力を得て乗員の膝を保護することができる。   As described above, when the knee airbag 28 is deployed when the grab door 12 is in the open state, the connecting portion 50 between the outer member 14 and the box member 16 receives a reaction force from the knee airbag 28. After that, the connecting member 32 slides to the front side of the vehicle to the closed position (the position indicated by the two-dot chain line in FIG. 1), so that the knee airbag 28 obtains a reaction force from the grab door 12 and eventually the instrument panel 26. Can protect the occupant's knees.

さらに、ボックス部材１６は連結部材３２によって回転可能にガイド部２０に支持されている。そのため、グラブドア１２が開状態の際にボックス部材１６と結合部材３６との固定を解除することで収納空間２２が車両後方側（乗員側）を向いて開口する。このとき、グラブドア１２の車両前方側に配置されているエアコンフィルタ３８が車室内と連通されるため、エアコンフィルタ（図示せず）の交換作業が容易になる。なお、作業性の向上についてはエアコンフィルタに限られず、例えばグラブドア１２の車両前方側に配置されるヒューズボックスなどについても同様である。   Further, the box member 16 is rotatably supported by the guide portion 20 by the connecting member 32. Therefore, when the grab door 12 is in the open state, the storage space 22 opens toward the vehicle rear side (occupant side) by releasing the fixation between the box member 16 and the coupling member 36. At this time, since the air conditioner filter 38 disposed on the vehicle front side of the grab door 12 communicates with the vehicle interior, replacement work of the air conditioner filter (not shown) is facilitated. The improvement in workability is not limited to the air conditioner filter, and the same applies to, for example, a fuse box disposed on the vehicle front side of the grab door 12.

なお、本発明は上述した実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更をすることが可能であることは勿論である。   In addition, this invention is not limited to embodiment mentioned above, Of course, a various change is possible in the range which does not deviate from the meaning of this invention.

例えば、本実施形態においては、インストルメントパネル２６とアウタ部材１４が別体に成形されていたが、インストルメントパネル２６とアウタ部材１４は一体に形成されていてもよい。その場合、インストルメントパネル２６にガイド部２０が設けられてボックス部材１６がスライド移動可能に連結される。   For example, in the present embodiment, the instrument panel 26 and the outer member 14 are formed separately, but the instrument panel 26 and the outer member 14 may be integrally formed. In that case, the guide part 20 is provided in the instrument panel 26, and the box member 16 is connected so that sliding movement is possible.

また、連結部材３２はボックス部材１６と別部材として構成されていたが、連結部材３２はボックス部材１６と一体に成形されていてもよい。つまり、ボックス部材１６の外壁１６Ｂの一部が車幅方向外側に突出して連結部材３２を構成し、ガイド部２０上を摺動してもよい。   Further, although the connecting member 32 is configured as a separate member from the box member 16, the connecting member 32 may be formed integrally with the box member 16. That is, a part of the outer wall 16B of the box member 16 may protrude outward in the vehicle width direction to form the connecting member 32 and slide on the guide portion 20.

さらに、本実施形態において、エアバッグモジュール１８はボックス部材１６の車両下側に設けられていたが、グラブドア１２に内蔵させてもよい。   Furthermore, in the present embodiment, the airbag module 18 is provided on the vehicle lower side of the box member 16, but may be incorporated in the grab door 12.
