Description

エアバッグ装置Airbag device
　本発明は、エアバッグを展開することによって車両内の乗員を保護するエアバッグ装置に関する。特に、車両のインストルメントパネル（インパネ）の内部に配置され、主に助手席の乗員を保護する助手席用エアバッグ装置に関する。 The present invention relates to an airbag device that protects an occupant in a vehicle by deploying the airbag. In particular, the present invention relates to an airbag device for a passenger seat that is disposed inside an instrument panel (instrument panel) of a vehicle and mainly protects passengers in the passenger seat.
　一般に、助手席用エアバッグ装置は、膨張ガスを発生するインフレータと、当該ガスによって膨張展開するエアバッグとをインストルメントパネル内部に収容した構造を採用する。車両衝突時には、インフレータが作動してエアバッグが膨張し、車両内部に向かって展開することによって乗員の前方移動を拘束する。 Generally, a passenger airbag device employs a structure in which an inflator that generates inflation gas and an airbag that is inflated and deployed by the gas are accommodated inside the instrument panel. In the event of a vehicle collision, the inflator is actuated to inflate the airbag and deploy toward the inside of the vehicle to restrain the passenger from moving forward.
　近年では、車両が障害物（対向車等）に対して真正面から衝突する正面衝突の他に、車両の一部に障害物が衝突する場合（オフセット衝突）や、車両の一部が障害物に対して斜め方向から衝突する場合等、種々の衝突形態での安全性が要求されるようになってきた。 In recent years, in addition to a frontal collision in which a vehicle collides with an obstacle (such as an oncoming vehicle) from the front, an obstacle collides with a part of the vehicle (offset collision), or a part of the vehicle becomes an obstacle. On the other hand, safety in various types of collisions has been required, such as when colliding from an oblique direction.
　図１は、運転席及び助手席にエアバッグ装置を備えた従来の車両（左ハンドル仕様）の構造を示す平面図であり、真正面よりもずれた位置の対象物（障害物）に対して０°の角度で進入する様子を示す。ドライバー１０の正面に位置するステアリングホイール１４の内部には、運転席用エアバッグ１６が収容され、衝突が発生した時に乗員に向かって展開するようになっている。助手席の乗員１２の正面に位置するインストルメントパネル（２４）の内部には、助手席用のエアバッグ１８が収容され、衝突が発生した時に乗員に向かって展開するようになっている。エアバッグ１４，１８は、衝突センサの信号で作動するインフレータ（図示せず）から供給される膨張ガスによって膨張する。 FIG. 1 is a plan view showing a structure of a conventional vehicle (left-hand drive specification) equipped with an airbag device in a driver seat and a passenger seat, and is 0 with respect to an object (obstacle) at a position shifted from the front. Shows approach at an angle of °. A driver's seat airbag 16 is accommodated inside the steering wheel 14 located in front of the driver 10 and is deployed toward the occupant when a collision occurs. Inside the instrument panel (24) located in front of the passenger 12 in the passenger seat, an airbag 18 for the passenger seat is accommodated and deployed toward the passenger when a collision occurs. The airbags 14 and 18 are inflated by an inflation gas supplied from an inflator (not shown) that is operated by a signal from the collision sensor.
　図２は、運転席及び助手席にエアバッグ装置を搭載した従来の車両の構造を示す平面図であり、真正面よりもずれた位置の対象物（障害物）に対して所定の角度θで進入する様子を示す。図３は、図２の状態で対象物（障害物）に衝突した後に車体が回転する様子を示す。図３のような状況では、助手席の乗員１２が助手席用エアバッグ１８の横を滑って、運転席と助手席の間のセンターコンソールに衝突する恐れがある。この場合、乗員１２はセンターコンソールへの直接的な衝突による傷害に加えて、頭部回転による脳傷害が発生する可能性がある。この脳傷害指標は、ＢＲＩＣ（Brain Rotational Injury Criteria）という。 FIG. 2 is a plan view showing a structure of a conventional vehicle in which an airbag device is mounted on a driver seat and a passenger seat, and enters at a predetermined angle θ with respect to an object (obstacle) at a position shifted from the front. It shows how to do. FIG. 3 shows how the vehicle body rotates after colliding with an object (obstacle) in the state of FIG. In the situation as shown in FIG. 3, there is a possibility that the passenger 12 in the passenger seat slides beside the passenger seat airbag 18 and collides with the center console between the driver seat and the passenger seat. In this case, there is a possibility that the occupant 12 may suffer brain injury due to head rotation in addition to injury due to direct collision with the center console. This brain injury index is called BRIC (BrainBRotational Injury Criteria).
　ところで、上記のようなエアバッグ装置においては、エアバッグの展開挙動を安定化させることが重要である。 Incidentally, in the airbag apparatus as described above, it is important to stabilize the deployment behavior of the airbag.
　本発明は、上記のような状況に鑑みてなされたものであり、簡素な構造でありながら、エアバッグの安定した展開挙動を得ることが可能なエアバッグ装置を提供することを目的とする。 The present invention has been made in view of the above situation, and an object of the present invention is to provide an airbag device capable of obtaining a stable deployment behavior of an airbag while having a simple structure.
　上記課題を解決するために、本発明に係るエアバッグ装置に使用されるエアバッグは、シートに着座した乗員の正面に展開して当該乗員の前方への移動を拘束するメインバッグと；前記メインバッグの少なくとも片側の側部に位置するサブバッグと；前記メインバッグの内部に配置され、当該メインバッグの展開形状を規制するメインバッグパネルと；前記サブバッグの内部に配置され、当該サブバッグの展開形状を規制するサブバッグパネルとを備える。そして、前記メインバッグパネルと前記サブバッグパネルを透視したときに、前後方向の位置、上下方向の位置、側面から見たときの傾斜角度、のうちの少なくとも１つの要素が互いに異なるように配置される。 In order to solve the above problems, an airbag used in an airbag device according to the present invention is a main bag that is deployed in front of an occupant seated on a seat and restrains the occupant from moving forward; A sub-bag located on at least one side of the bag; a main bag panel disposed inside the main bag and restricting a deployed shape of the main bag; and disposed within the sub-bag, A sub-bag panel that regulates the unfolded shape. And when the main bag panel and the sub bag panel are seen through, at least one element of the position in the front-rear direction, the position in the vertical direction, and the inclination angle when viewed from the side is different from each other. The
　なお、メインバッグ領域の「側部」とは、当該エアバッグが保護しようとする乗員のシートの中心を通るラインに対して、車両の左右横方向にずれた位置であり、正面衝突の際に乗員を保護するメインバッグ領域の主要部分の外側と言うことができる。そして、サブバッグはメインバッグに対して上下又は前後にずれて配置されてもよい。
　また、「前後方向」とは車両の進行方向を前方、その反対方向を後方とした場合の前後の方向である。「上下方向」とは、文字通り車両の垂直方向上側と下側の方向を意味する。「側面から見たときの傾斜角度」とは、側面から透視観察したときに、前端部と後端部との高低差に基づく傾斜の角度を意味する。 The “side” of the main bag region is a position shifted in the lateral direction of the vehicle with respect to a line passing through the center of the seat of the occupant to be protected by the airbag. It can be said that it is outside the main part of the main bag region that protects the passenger. And a subbag may be arrange | positioned shifting | deviating up and down or front and back with respect to the main bag.
The “front-rear direction” is a front-rear direction when the traveling direction of the vehicle is the front and the opposite direction is the rear. “Up and down direction” literally means the upper and lower directions in the vertical direction of the vehicle. “An inclination angle when viewed from the side surface” means an angle of inclination based on a height difference between the front end portion and the rear end portion when seen through from the side surface.
　上記のような構成の本発明によれば、乗員が前方に移動しようとする場合にはメインバッグ領域によって当該乗員を保護する。一方、乗員が斜め前方へ移動した場合には、サブバッグ領域によって当該乗員の移動を拘束し、センターコンソールへの衝突を回避可能となる。そして、メインバッグパネルとサブバッグパネルの、前後方向の位置、上下方向の位置、側面から見たときの傾斜角度のうちの少なくとも１つの要素を互いに異なるように配置することにより、全体としての展開形状を比較的自由に設定することが可能となる。例えば、膨張展開したときに隣り合う２つのバッグの干渉を抑制することが可能となる。 According to the present invention configured as described above, when the occupant intends to move forward, the occupant is protected by the main bag region. On the other hand, when the occupant moves obliquely forward, the movement of the occupant is restrained by the sub-bag region, and a collision with the center console can be avoided. The main bag panel and the sub-bag panel are deployed as a whole by disposing at least one element of the position in the front-rear direction, the position in the up-down direction, and the inclination angle when viewed from the side so as to be different from each other. The shape can be set relatively freely. For example, it is possible to suppress interference between two adjacent bags when inflated and deployed.
　メインバッグパネルとサブバッグパネルは、メインバッグの最大幅位置とサブバッグの最大幅位置とが干渉し合わないように配置することが好ましい。特に、上下方向の位置、側面から見たときの傾斜角度が異なるように配置することが好ましい。これにより、膨張展開したときに隣り合う２つのバッグの最大幅部分同士が干渉して、エアバッグ全体の展開形状、展開挙動に悪影響を及ぼすことを抑制可能となる。例えば、一方のバッグの凸部と他方のバッグの凹部とが対向（接触）するように配置することで、展開挙動がより安定する。 The main bag panel and the sub bag panel are preferably arranged so that the maximum width position of the main bag and the maximum width position of the sub bag do not interfere with each other. In particular, it is preferable to arrange so that the position in the vertical direction and the inclination angle when viewed from the side are different. Thereby, when the inflated and deployed, the maximum width portions of the two adjacent bags interfere with each other, and the adverse effect on the deployed shape and deployment behavior of the entire airbag can be suppressed. For example, the deployment behavior is further stabilized by arranging the convex portion of one bag and the concave portion of the other bag to face (contact).
　メインバッグパネルとサブバッグパネルを矩形に成形し、メインバッグパネルの第１の辺と当該第１の辺と対向する第２の辺を、メインバッグの左右内側面に縫製によって連結することができる。同様に、サブバッグパネルの第１の辺と当該第１の辺と対向する第２の辺を、サブバッグの左右内側面に縫製によって連結することができる。このような構成を採用することにより、特に、横方向へのエアバッグの広がり過ぎや、不適切な展開形状を回避することが可能となる。 The main bag panel and the sub bag panel can be formed into a rectangular shape, and the first side of the main bag panel and the second side facing the first side can be connected to the left and right inner surfaces of the main bag by sewing. . Similarly, the first side of the sub-bag panel and the second side facing the first side can be connected to the left and right inner surfaces of the sub-bag by sewing. By adopting such a configuration, it is possible to avoid an excessive spread of the airbag in the lateral direction and an inappropriate deployment shape.
　また、メインバッグパネル及びサブバッグパネルを、各々台形に成形することができる。そして、例えば、メインバッグパネルの台形の長底辺とサブバッグパネルの台形の短底辺とが前後方向において同一側に位置し、メインバッグパネルの台形の短底辺とサブバッグパネルの台形の長底辺とが同一側に位置するように配置さすることにより、前後方向においても、メインバッグとサブバッグの凹部分と凸部分を組み合わせることができる。その結果、メインバッグとサブバッグの横方向の干渉のみならず、前後方向の干渉も緩和可能となる。 Also, the main bag panel and the sub bag panel can each be formed into a trapezoid. And, for example, the long bottom side of the trapezoid of the main bag panel and the short bottom side of the trapezoid of the sub bag panel are located on the same side in the front-rear direction, and the short bottom side of the trapezoid of the main bag panel and the long bottom side of the trapezoid of the sub bag panel By arranging them so that they are located on the same side, the concave portions and the convex portions of the main bag and the sub bag can be combined also in the front-rear direction. As a result, not only the lateral interference between the main bag and the sub bag, but also the longitudinal interference can be mitigated.
　メインバッグパネルを前方が低く後方が高くなるように傾斜させ、サブバッグパネルを前方が高く後方が低くなるように傾斜させることが好ましい。また、メインバッグパネルの最高位が、サブバッグパネルの最高位よりも高くなるように配置することができる。なお、「最高位」とは、当該パネルの最も上方に位置する部分を意味する。
　このような構成を採用することにより、所謂アウト・オブ・ポジション（異常接近）の状況において、膨張ガスが乗員の頭部方向に直接流れるのではなく、多くのガスはメインバッグパネルに沿って斜め上方に向かって流れるため、当該状況下の乗員の傷害値を低減させることが期待される。他方、サブバッグ側においては、最大幅位置が中心から若干上であることと、サブバッグパネルによる膨張ガスの整流作用により、バッグ上部が速やかに展開して乗員の横方向への移動や頭部回転を速やかに拘束することが可能となる。 It is preferable that the main bag panel is inclined so that the front is low and the rear is high, and the sub bag panel is inclined so that the front is high and the rear is low. Moreover, it can arrange | position so that the highest position of a main bag panel may become higher than the highest position of a subbag panel. Note that the “highest rank” means a portion located on the uppermost side of the panel.
By adopting such a configuration, in a so-called out-of-position (abnormal approach) situation, the inflation gas does not flow directly in the direction of the occupant's head, but a large amount of gas is slanted along the main bag panel. Since it flows upward, it is expected to reduce the injury value of the passenger under the situation. On the other hand, on the sub-bag side, the maximum width position is slightly above the center and the expansion of the expansion gas by the sub-bag panel quickly expands the upper portion of the bag so that the occupant can move laterally and the head. It becomes possible to restrain rotation quickly.

FIG. 4 is a plan view showing a schematic configuration of a vehicle equipped with the airbag apparatus according to the present invention. The airbag apparatus according to the present invention, a main bag 18 that is deployed in front of an occupant seated on a seat and restrains the occupant from moving forward; is located on at least one side (for example, the vehicle center side) of the main bag 18 A subbag 20.

Although all cases are assumed to be mounted on a left-hand drive vehicle, it goes without saying that the right-hand drive vehicle is reversed right and left.
　本発明に係るエアバッグ装置に使用されるエアバッグは、上述したメインバッグ１８とサブバッグ２０に加えて、メインバッグ１８の内部に配置され、当該メインバッグ１８の展開形状を規制するメインバッグパネル２６と；サブバッグ２０の内部に配置され、当該サブバッグ２０の展開形状を規制するサブバッグパネル２８とを備える。 In addition to the main bag 18 and the sub bag 20 described above, the airbag used in the airbag apparatus according to the present invention is disposed inside the main bag 18 and regulates the deployed shape of the main bag 18. 26; and a sub bag panel 28 that is disposed inside the sub bag 20 and regulates the deployed shape of the sub bag 20.
　メインバッグ１８はサブバッグ２０に比べて左右方向に大きく広がる用に成形されている。一方、サブバッグ２０は、メインバッグ１８の左側（センターコンソール側）において、メインバッグ１８よりも乗員側（後方）に突出するように成形されており、これによって乗員の横方向への移動を拘束するとともに、頭部の回転を抑制することが可能となる。 The main bag 18 is formed so as to expand greatly in the left-right direction compared to the sub bag 20. On the other hand, the sub bag 20 is formed on the left side (center console side) of the main bag 18 so as to protrude toward the occupant side (rear side) from the main bag 18, thereby restraining the movement of the occupant in the lateral direction. In addition, the rotation of the head can be suppressed.
　メインバッグ１８の上面後方とサブバッグ２０の上面後方とは、テザー２２によって連結されている。また、メインバッグ１８の乗員側面（後面）下方とサブバッグ２０の乗員側面（後面）下方とは、タイパネル２４によって連結されている。これらのテザー２２、タイパネル２４によって、両バッグ１８，２０の相対的な位置関係が良好に保たれる。 The upper back of the main bag 18 and the upper back of the sub bag 20 are connected by a tether 22. Further, the occupant side (rear) lower portion of the main bag 18 and the occupant side (rear) lower portion of the sub bag 20 are connected by a tie panel 24. By the tether 22 and the tie panel 24, the relative positional relationship between the two bags 18 and 20 is maintained well.
　次に、メインバッグ１８の内部に配置されたメインバッグパネル２６と、サブバッグ２０の内部に配置されたサブバッグパネル２８について詳細に説明する。図６（Ａ）に示すように、メインバッグパネル２６は底辺２６ａ、２６ｂを有する台形に成形されており、底辺２６ａ、２６ｂの幅は、各々Ｗ４，Ｗ３として表現されている。そして、Ｗ４がＷ３より小さくなるように設定されている。なお、Ｗ４とＷ３とを同一幅にしたり、Ｗ４をＷ３より大きくなるように設定することもできる。そして、メインバッグ１８の内部においては、底辺２６ａが後縁（乗員側端部）となり、底辺２６ｂが前縁（ダッシュボード側端部）となる。 Next, the main bag panel 26 arranged in the main bag 18 and the sub bag panel 28 arranged in the sub bag 20 will be described in detail. As shown in FIG. 6A, the main bag panel 26 is formed into a trapezoid having bottom sides 26a and 26b, and the widths of the bottom sides 26a and 26b are expressed as W4 and W3, respectively. W4 is set to be smaller than W3. Note that W4 and W3 can have the same width, or W4 can be set to be larger than W3. And in the inside of the main bag 18, the base 26a becomes a rear edge (occupant side end), and the base 26b becomes a front edge (dashboard side end).
　図６（Ｂ）に示すように、サブバッグパネル２８は底辺２８ａ、２８ｂを有する台形に成形されており、底辺２８ａ、２８ｂの幅は、各々Ｗ２，Ｗ１として表現されている。そして、Ｗ１がＷ２より小さくなるように設定されている。なお、Ｗ１とＷ２とを同一幅にしたり、Ｗ１をＷ２より大きくなるように設定することもできる。そして、サブバッグ２０の内部においては、底辺２８ａが後縁（乗員側端部）となり、底辺２８ｂが前縁（ダッシュボード側端部）となる。 As shown in FIG. 6B, the sub-bag panel 28 is formed into a trapezoid having bottom sides 28a and 28b, and the widths of the bottom sides 28a and 28b are expressed as W2 and W1, respectively. W1 is set to be smaller than W2. Note that W1 and W2 can be set to have the same width, or W1 can be set to be larger than W2. And in the inside of the subbag 20, the base 28a becomes a rear edge (occupant side end), and the base 28b becomes a front edge (dashboard side end).
　メインバッグパネル２６は、底辺２６ａ、２６ｂ以外の側辺がメインバッグ１８の内側面に縫製によって固定される。同様に、サブバッグパネル２８についても、底辺２８ａ、２８ｂ以外の側辺がメインバッグ２０の内側面に縫製によって固定される。メインバッグパネル２６とサブバッグパネル２８の縫製位置については、図５（Ｂ）、図７、図８（Ｂ）、図１０に明瞭に示されている。パネル２６，２８が縫製された当該エアバッグ１８，２０の部分は、膨張が規制されてライン状の窪みとなる。 The side of the main bag panel 26 other than the bottom sides 26a and 26b is fixed to the inner surface of the main bag 18 by sewing. Similarly, with respect to the sub-bag panel 28, the sides other than the bottom sides 28a and 28b are fixed to the inner side surface of the main bag 20 by sewing. The sewing positions of the main bag panel 26 and the sub bag panel 28 are clearly shown in FIG. 5 (B), FIG. 7, FIG. 8 (B), and FIG. The portions of the airbags 18 and 20 where the panels 26 and 28 are sewn are restricted from being inflated to form line-shaped depressions.
　図５に示すように、メインバッグ１８及びサブバッグ２０を透視した状態において、メインバッグパネル２６とサブバッグパネル２８とは、前後方向にずれ（図５（Ａ）参照）、上下方向にずれ（図５（Ｃ）参照）、更に、側面から見たときの（縫製ラインの）傾斜角度が互いに異なるように配置されている。本発明においては、これらの要素の何れか１つをずらすことが必要である。本発明においては、メインバッグパネル２６は、乗員側に位置する後縁部２６ａが高く、ダッシュボート側に位置する前縁部２６ｂが低くなるように傾斜している。他方、サブバッグパネル２８は、乗員側に位置する後縁部２８ａが低く、ダッシュボート側に位置する前縁部２８ｂが高くなるように傾斜している。また、メインバッグパネル２６の最高位が、サブバッグパネル２８の最高位よりも高くなるように配置されている。 As shown in FIG. 5, in a state where the main bag 18 and the sub bag 20 are seen through, the main bag panel 26 and the sub bag panel 28 are displaced in the front-rear direction (see FIG. 5A) and displaced in the vertical direction ( Furthermore, they are arranged so that the inclination angles (of the sewing line) when viewed from the side are different from each other. In the present invention, it is necessary to shift any one of these elements. In the present invention, the main bag panel 26 is inclined such that the rear edge portion 26a located on the passenger side is high and the front edge portion 26b located on the dashboard side is low. On the other hand, the sub-bag panel 28 is inclined so that the rear edge portion 28a located on the passenger side is low and the front edge portion 28b located on the dashboard side is high. Further, the highest position of the main bag panel 26 is arranged to be higher than the highest position of the sub bag panel 28.
　上記のように、パネル２６，２８の形状及び、配置を工夫することによって、メインバッグ１８の最大幅位置１８Ｘとサブバッグ２０の最大幅位置２０Ｘとが干渉し合わないようになっている（図８（Ｂ）、図９参照）。その結果、エアバッグが膨張展開したときにメインバッグ１８とサブバッグ２０の最大幅部分同士が干渉して、エアバッグ全体の展開挙動が悪化するのを抑制可能となる。すなわち、メインバッグ１８とサブバッグ２０との相対的な展開形状を制御することにより、エアバッグ全体としての展開の安定化を図ることができる。更に、メインバッグ１８とサブバッグ２０の相対的な関係において、凹部と凸部が組み合わさるようにすれば、バッグの容量を小さくすることが可能となる。 As described above, the maximum width position 18X of the main bag 18 and the maximum width position 20X of the sub bag 20 do not interfere with each other by devising the shape and arrangement of the panels 26 and 28 (FIG. 8 (B) and FIG. 9). As a result, when the airbag is inflated and deployed, it is possible to prevent the maximum width portions of the main bag 18 and the subbag 20 from interfering with each other to deteriorate the deployment behavior of the entire airbag. That is, by controlling the relative deployment shape of the main bag 18 and the subbag 20, it is possible to stabilize the deployment of the airbag as a whole. Furthermore, if the concave portion and the convex portion are combined in the relative relationship between the main bag 18 and the sub bag 20, the capacity of the bag can be reduced.
　メインバッグ１８とサブバッグ２０とを別々に考えた場合にも、本発明にはメリットがある。メインバッグパネル２６を後方斜め上に向かって傾斜させることにより、所謂アウト・オブ・ポジション（異常接近）の状況において、乗員の頭部方向に直接流れるのではなく、多くのガスはメインバッグパネル２６に沿って斜め上方に向かって流れるため、当該状況下の乗員の傷害値を低減させることが期待できる。このような効果は、メインバッグ１８の最大幅位置１８Ｘを中心から若干下げることでより顕著となる。
　他方、サブバッグ２０側においては、最大幅位置２０Ｘが中心から若干上であることと、サブバッグパネル２８による膨張ガスの整流作用により、バッグ上部が速やかに展開して乗員の横方向への移動や頭部回転を速やかに拘束することが可能となる。 Even when the main bag 18 and the sub bag 20 are considered separately, the present invention is advantageous. By tilting the main bag panel 26 rearward and obliquely upward, in a so-called out-of-position (abnormal approach) situation, a large amount of gas does not flow directly toward the occupant's head, but a large amount of gas flows. Therefore, it can be expected that the injury value of the occupant in the situation is reduced. Such an effect becomes more remarkable by slightly lowering the maximum width position 18X of the main bag 18 from the center.
On the other hand, on the side of the sub bag 20, the maximum width position 20 </ b> X is slightly above the center, and due to the rectifying action of the inflation gas by the sub bag panel 28, the upper part of the bag is quickly deployed and the occupant moves in the lateral direction. And head rotation can be restrained quickly.
　図１０は、本発明に係るエアバッグの装置の作用を説明するための側面図である。例えば、車両の衝突が発生した場合、インフレータ３２から供給されるガスが最初にメインバッグ１８に入り、その後、メインバッグ１８とサブバッグ２０との連結部分にある連通孔（図示せず）を介してサブバッグ２０にもガスが供給され、両方のバッグ１８，２０が展開する。乗員が前方に移動しようとする場合にはメインバッグ１８によって当該乗員を保護する。一方、乗員が斜め前方へ移動した場合には、サブバッグ２０によって当該乗員の移動を拘束し、センターコンソールへの衝突を回避可能となる。なお、上記の場合には単一のインフレータ３２を使用しているが、メインバッグ１８とサブバッグ２０とで各々別々のインフレータを使用することも可能である。 FIG. 10 is a side view for explaining the operation of the airbag apparatus according to the present invention. For example, when a vehicle collision occurs, the gas supplied from the inflator 32 first enters the main bag 18 and then passes through a communication hole (not shown) in the connecting portion between the main bag 18 and the sub bag 20. Thus, gas is also supplied to the sub-bag 20, and both bags 18 and 20 are deployed. When the occupant intends to move forward, the occupant is protected by the main bag 18. On the other hand, when the occupant moves obliquely forward, the movement of the occupant is restrained by the sub-bag 20, and a collision with the center console can be avoided. In the above case, a single inflator 32 is used. However, it is also possible to use separate inflators for the main bag 18 and the sub bag 20.
　以上、本発明の実施例について説明したが、本発明はこれらの実施例に何ら限定されるものではなく、特許請求の範囲に示された技術的思想の範疇において変更可能なものである。 Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can be modified within the scope of the technical idea shown in the claims.
