さらに、本実施の形態では、第2の折畳工程の一部として、集積部64は、エアバッグ収納部28に収納可能な幅寸法よりさらに小さい幅寸法に折り畳み、保護部42の集積部64の上側及び下側を基部41の上部折畳部61及び下部折畳部62で包むように沿わせるのみならず、集積部64の両側部にも、基部41の部分すなわち上下の折畳部61,62の両側方向の端部の部分を沿わせ、いわば、保護部42の集積部64の上下両側に、基部41の折畳部61,62を沿わせて、エアバッグ1の展開方向である乗員側を除いて、保護部42を基部41で包み込むようにする。   Furthermore, in the present embodiment, as part of the second folding step, the stacking unit 64 is folded to a width smaller than the width that can be stored in the airbag storage unit 28, and the stacking unit 64 of the protection unit 42 is folded. Not only along the upper and lower folds 61 and 62 of the base 41 but also on both sides of the stacking part 64, that is, the base 41, that is, the upper and lower folds 61, Along with the end portions of both sides of 62, so to speak, the folds 61 and 62 of the base 41 are placed along the upper and lower sides of the stacking portion 64 of the protection portion 42, so Except for the side, the protection part 42 is wrapped with the base part 41.

さらに、本実施の形態では、第3の折畳工程として、インフレータ22からガスが供給されるガス導入部より基端部38側の部分を、下側から先端側に折り返し、集積部64及び下部折畳部62の下側に沿って配置し、案内展開部66を構成する。   Furthermore, in the present embodiment, as the third folding step, the portion on the base end portion 38 side from the gas introduction portion to which gas is supplied from the inflator 22 is folded back from the lower side to the tip end side, and the stacking portion 64 and the lower portion It arrange | positions along the lower side of the folding part 62, and comprises the guidance expansion | deployment part 66. FIG.

そして、必要に応じてエアバッグ1に図示しないラッピングを被せ、図11に示すように、エアバッグ1を所定の形状に折り畳んだ状態で保持し組立体を構成する。   Then, if necessary, the airbag 1 is covered with a wrapping (not shown), and as shown in FIG. 11, the airbag 1 is held in a predetermined shape to constitute an assembly.

次いで、この組立体を、開口部21aを介してケース体21に挿入し、ケース体21の取付孔21cにリテーナ24の取付ボルト24bを貫通させ、ケース体21の外側から取付ボルト24bにナット24cを螺合して、組立体すなわちエアバッグ1、インフレータ22、及びリテーナ24などをケース体21に固定する。次いで、表板部26aが開口部21aすなわちエアバッグ1を覆うようにして、ケース体21にカバー体26を取り付けることにより、エアバッグ装置2が構成される。   Next, this assembly is inserted into the case body 21 through the opening 21a, the mounting bolt 24b of the retainer 24 is passed through the mounting hole 21c of the case body 21, and the nut 24c is attached to the mounting bolt 24b from the outside of the case body 21. Then, the assembly, that is, the airbag 1, the inflator 22, the retainer 24, and the like are fixed to the case body 21. Next, the airbag device 2 is configured by attaching the cover body 26 to the case body 21 so that the front plate portion 26a covers the opening 21a, that is, the airbag 1.

そして、ケース体21のブラケット21eを、ボルト21f及びナット21gなどの取付具を用いて車体の取付部材29に固定し、カバー体26の表板部26aがパネル5と面一になるようにエアバッグ装置2を車体に取り付けるとともに、インフレータ22に接続したハーネス22bを制御手段に電気的に連結し、図1に示すように、エアバッグ装置2が車体に設置される。   Then, the bracket 21e of the case body 21 is fixed to the mounting member 29 of the vehicle body using a fixture such as a bolt 21f and a nut 21g, and the air is so that the front plate portion 26a of the cover body 26 is flush with the panel 5. While attaching the bag apparatus 2 to a vehicle body, the harness 22b connected to the inflator 22 is electrically connected to the control means, and the airbag apparatus 2 is installed on the vehicle body as shown in FIG.

次に、このエアバッグ装置2の動作を説明する。   Next, the operation of the airbag device 2 will be described.

図1に示す状態から、制御装置が自動車の正面衝突などの衝撃を検出すると、この制御装置はハーネス22bを通じて起動信号である電力を供給し、インフレータ22を作動させる。そして、インフレータ22からエアバッグ1内にガスが供給されると、エアバッグ1は、ケース体21の内側で膨張し、まず、ラッピングを破断し、ついで、カバー体26をテアライン26cで破断して、エアバッグ1をケース体21から車室4に膨張展開させる。より詳細には、まず、インフレータ22から供給されるガスは、リテーナ24のリテーナ本体24aで拡散されつつ、エアバッグ1の基部41のガス供給部に供給される。すると、まず、エアバッグ1の基部41が膨張展開を開始するが、特に、このガス供給部に直接的に連通し、かつ、ガスの流路が直線的、すなわちロールや蛇腹となっていない、上部折畳部61、下部折畳部62、及び案内展開部66に迅速にガスが供給され、これら上部折畳部61、下部折畳部62、及び案内展開部66が展開する。そして、図2に示すように、これら上部折畳部61、下部折畳部62、及び案内展開部66の展開により、集積部64は、所定の方向すなわち乗員側に、安定して押し出される。この後、集積部64は、両側から折り返した部分が復帰方向に変形して幅方向に拡大するとともに、ロール状に折り畳んだ部分にガスが供給されて、乗員側に、より詳細には乗員の下肢部Aに沿って後側上方に膨張展開し、下肢部Aを膝A1の部分を含んで覆い、乗員の下方への滑り込みを防止して保護する。また、集積部64は、第1の隔壁31及び第2の隔壁32により区画されているため、まず、他の部分より下側に位置する基部側チャンバー44が展開し、次いで、基部側チャンバー44の上側に位置して中間チャンバー45が展開し、さらに、他の部分より上側に位置して先端部側チャンバー46が展開する。そして、先端部側チャンバー46の部分が、慣性で前方に移動してくる乗員の膝A1に対向して膨張展開し、乗員の膝A1を拘束して保護するとともに、結果的に乗員の腰部の移動を抑制して、乗員の車体に対する相対的な移動を効果的に抑制し、パネル5や車室4に進入してくる床面などに直接当接することなどを抑制して保護する。そして、エアバッグ1は、最終的に、図3に示す形状に膨張展開する。   When the control device detects an impact such as a frontal collision of an automobile from the state shown in FIG. 1, the control device supplies electric power as an activation signal through the harness 22b and activates the inflator 22. When gas is supplied from the inflator 22 into the airbag 1, the airbag 1 inflates inside the case body 21, first ruptures the wrapping, and then breaks the cover body 26 at the tear line 26 c. The airbag 1 is inflated and deployed from the case body 21 to the vehicle compartment 4. More specifically, first, the gas supplied from the inflator 22 is supplied to the gas supply portion of the base portion 41 of the airbag 1 while being diffused by the retainer body 24a of the retainer 24. Then, first, the base portion 41 of the airbag 1 starts to inflate and deploy. In particular, the base portion 41 communicates directly with the gas supply portion, and the gas flow path is linear, that is, not a roll or bellows. Gas is rapidly supplied to the upper foldable portion 61, the lower foldable portion 62, and the guide unfolding portion 66, and the upper foldable portion 61, the lower foldable portion 62, and the guide unfolding portion 66 are unfolded. Then, as shown in FIG. 2, the unfolding of the upper folding part 61, the lower folding part 62, and the guide unfolding part 66 causes the stacking part 64 to be stably pushed out in a predetermined direction, that is, the passenger side. Thereafter, the stacking portion 64 is deformed in the returning direction by the folded portion from both sides and expanded in the width direction, and gas is supplied to the folded portion so that the passenger side, more specifically, the passenger's side The lower limb portion A is inflated and deployed along the lower limb portion A and covers the lower limb portion A including the portion of the knee A1, thereby preventing and protecting the occupant from slipping downward. In addition, since the accumulation unit 64 is partitioned by the first partition wall 31 and the second partition wall 32, first, the base side chamber 44 positioned below the other part is developed, and then the base side chamber 44 is expanded. The intermediate chamber 45 is deployed on the upper side of the first portion, and the distal end side chamber 46 is deployed on the upper side of the other portions. Then, the front end side chamber 46 part expands and deploys against the occupant's knee A1 moving forward due to inertia, restrains and protects the occupant's knee A1, and as a result of the occupant's waist By suppressing the movement, the relative movement of the occupant relative to the vehicle body is effectively suppressed, and the direct contact with the panel 5 or the floor surface entering the passenger compartment 4 is suppressed and protected. Then, the airbag 1 is finally inflated and deployed into the shape shown in FIG.

このように、本実施の形態によれば、乗員の膝A1を含む下肢部A保護可能なエアバッグ装置2について、集積部64のガス導入部側から上下側に沿って上部折畳部61及び下部折畳部62を配置したため、インフレータ22が動作すると、これら上部折畳部61及び下部折畳部62が迅速に膨張展開することにより、これら上部折畳部61及び下部折畳部62で案内して、集積部64を安定してケース体21のエアバッグ収納部28から開口部21aを介して車室4に押し出すことができる。そこで、車室4において、集積部64を幅方向に拡大するとともに、乗員側に、ここでは乗員に沿って円滑かつ迅速に膨張展開させ、乗員の下肢部を保護する好ましい特性を実現できる。すなわち、上部折畳部61及び下部折畳部62は、エアバッグ1の外殻を構成する上側基布部30aと下側基布部30bとを互いに離反させそれぞれ扁平に集積し、集積部64の外周部の反対側すなわち上下に沿わせて折り畳んだため、ガス導入部からガスが直接的に供給され、これら上部折畳部61及び下部折畳部62を迅速に展開できる。   As described above, according to the present embodiment, the airbag device 2 capable of protecting the lower limb portion A including the occupant's knee A1, the upper folding portion 61 and the upper folding portion 61 from the gas introduction portion side of the accumulation portion 64 along the upper and lower sides. Since the lower fold part 62 is disposed, when the inflator 22 is operated, the upper fold part 61 and the lower fold part 62 are rapidly expanded and deployed, so that the upper fold part 61 and the lower fold part 62 are guided. Thus, the accumulation portion 64 can be stably pushed out from the airbag storage portion 28 of the case body 21 to the vehicle compartment 4 through the opening portion 21a. Therefore, in the passenger compartment 4, it is possible to realize the preferable characteristic of protecting the occupant's lower limbs by expanding the accumulating portion 64 in the width direction and inflating and expanding on the occupant side along the occupant here. That is, the upper foldable portion 61 and the lower foldable portion 62 accumulate the flat portions by separating the upper base fabric portion 30a and the lower base fabric portion 30b constituting the outer shell of the airbag 1 from each other. Since the gas is directly supplied from the gas introduction part, the upper fold part 61 and the lower fold part 62 can be rapidly deployed.

また、本実施の形態では、集積部64の上下のみならず両側の部分も基部41を折り畳んだ部分で囲むようにしたため、上下左右の四方について安定して集積部64を案内できる。   In the present embodiment, not only the upper and lower sides of the stacking portion 64 but also the portions on both sides are surrounded by the folded portion of the base 41, so that the stacking portion 64 can be stably guided in the four directions of the upper, lower, left and right sides.

さらに、本実施の形態では、インフレータ22からガスが供給されるガス導入部より基端部38側の部分を、下側から先端側に折り返し、集積部64及び下部折畳部62の下側に沿って配置して、案内展開部66としたため、この案内展開部66が迅速に展開し、いわば長く折り返した部分が突っ張るようにして、ケース体21のエアバッグ収納部28の隙間を埋めて、展開する集積部64などを支持し、集積部64を安定して展開させることができる。   Furthermore, in the present embodiment, the portion on the base end portion 38 side from the gas introduction portion to which gas is supplied from the inflator 22 is folded back from the lower side to the distal end side, and below the stacking portion 64 and the lower folding portion 62. Since the guide deployment part 66 is quickly deployed, so that the part that is folded back long is stretched, the gap of the airbag storage part 28 of the case body 21 is filled, The stacking unit 64 to be deployed can be supported and the stacking unit 64 can be stably deployed.

また、集積部64は、乗員側の先端部36から上向きにロール状に折り畳まれて集積された後に両側部が中央側に折り重ねられて開口部21aの幅寸法より小さい幅寸法に集積したため、エアバッグ収納部28から押し出されると、まず、両側方向に広がり、次いで、上向きにロール状に折り畳んだ部分がほどけるようにして、安定した挙動で乗員の下肢部Aに沿って展開し、乗員の下肢部Aを保護する好ましい特性を実現できる。   Further, the stacking portion 64 is folded in a roll shape upward from the front end portion 36 on the occupant side, and then accumulated on a width dimension smaller than the width dimension of the opening portion 21a by folding both sides to the center side. When pushed out from the air bag storage portion 28, first, it spreads in both directions and then unfolds upward in a roll shape so that it unfolds along the limb A of the occupant with a stable behavior. The preferable characteristic which protects lower leg part A can be implement | achieved.

さらに、この集積部64は、各隔壁31,32により3個のチャンバー44,45,46に区画したため、各チャンバー44,45,46を順次膨張展開させる挙動を実現できる。   Further, since the accumulation unit 64 is partitioned into three chambers 44, 45, and 46 by the partition walls 31 and 32, it is possible to realize a behavior of sequentially expanding and deploying the chambers 44, 45, and 46.

また、エアバッグ1の折り畳み方法により、展開特性を向上できるため、エアバッグ1あるいはエアバッグ装置2の構成を複雑にする必要がなく、エアバッグ装置2の製造コストを低減できる。   Further, since the deployment characteristics can be improved by the folding method of the airbag 1, it is not necessary to make the configuration of the airbag 1 or the airbag device 2 complicated, and the manufacturing cost of the airbag device 2 can be reduced.

このようにして、エアバッグ1が、低い位置に設けられた狭い空間のエアバッグ収納部28から広く迅速に安定して膨張展開し、車両の座席に着席した乗員の下肢部Aを保護し、乗員の下方への滑り込み、いわゆるサブマリン現象を防止できるという好ましい特性のエアバッグ装置2を提供できる。   In this way, the airbag 1 is inflated and deployed widely and quickly from the airbag storage portion 28 in a narrow space provided at a low position, and protects the lower limb portion A of the occupant seated in the vehicle seat, It is possible to provide the airbag device 2 having a preferable characteristic that can prevent the passenger from slipping downward, the so-called submarine phenomenon.

Although the configuration along the part 62 and both sides is adopted, the configuration is not limited to this. For example, depending on the height position including the airbag device 2, the first foldable portion may be a bellows-like foldable portion, a foldable portion that is simply pressed and accumulated from the tip side, a plurality of roll portions, or these It can be a combination.

また、第2の折畳部を構成する上下の折畳部61,62は、図1に示すように、第1の折畳部としての集積部64の全体とケース体21の上下の壁部との間の上下の空間に沿って、集積部64の先端側すなわち開口部21a側に位置を揃えて形成する他、例えば、図12に示すように、上下の折畳部61,62を長く延設し、カバー体26の表板部26aの裏面側に沿って、集積部64の開口部21a側を横切るように、すなわち集積部64の開口部21a側をほぼ覆うように、すなわち、上下の折畳部61,62が互いに接触するか僅かに離間するように、上下の折畳部61,62を略L字状に延設してもよい。   Further, the upper and lower folding parts 61 and 62 constituting the second folding part are, as shown in FIG. 1, the entire stacking part 64 as the first folding part and the upper and lower wall parts of the case body 21. 12 along the upper and lower spaces between them, and the upper and lower folding parts 61 and 62 are elongated, for example, as shown in FIG. Extend along the back surface side of the front plate portion 26a of the cover body 26 so as to cross the opening portion 21a side of the stacking portion 64, that is, to substantially cover the opening portion 21a side of the stacking portion 64, that is, vertically The upper and lower folding parts 61 and 62 may be extended in a substantially L shape so that the folding parts 61 and 62 are in contact with each other or slightly separated from each other.

さらに、例えば、図13に示すように、上下の折畳部61,62は、集積部64の上下側の全体に沿う長さL1よりも短く、集積部64の上下側の約半分を覆う長さ寸法L2で形成し、集積部64の背面側すなわちインフレータ22側を覆うように形成しても良い。   Further, for example, as shown in FIG. 13, the upper and lower folding parts 61, 62 are shorter than the length L 1 along the entire upper and lower sides of the stacking part 64 and cover about half of the upper and lower sides of the stacking part 64. It may be formed with a length L2 so as to cover the back side of the integrated portion 64, that is, the inflator 22 side.
