Abstract

PURPOSE:To quickly expand an air bag and effectively mitigate a shock applied on a crew by forming through holes on an air bag, and covering the through holes with sheet-like elastic members having exhaust holes to exhaust gas in the air bag. CONSTITUTION:For example, four through holes 5 are formed on the back face side 2 of an air bag 1, sheet-like elastic members 6 of rubber or the like are provided on the through holes 5, and fixed by sewing, adhesive, or the like so as to cover the through holes 5. The respective elastic members 6 are formed with a proper number of exhaust holes 7 to exhaust gas in the air bag 1. In the early stage of beginning of expansion, the size of the exhaust holes 7 are small and an outflow gas quantity is small, and hence the air bag l is quickly expanded so as to complete expansion in a short time. When the inner pressure reaches the maximum value, the elastic members 6 deform largely, the size of the exhaust holes 7 largely spread, the inner gas is effectively exhausted through the exhaust holes 7, and hence a shock to a crew is surely mitigated.

【実施例】以下、本発明の実施例を図面に従って詳細に説明する。 EXAMPLES The following detailed description of the embodiments of the present invention with reference to the drawings.

【0008】図1は本発明に係るエアバッグシステムのエアバッグ1を示す斜視図である。 [0008] Figure 1 is a perspective view showing the air bag 1 of the airbag system according to the present invention. このエアバッグ1 The air bag 1
は、非通気性の可撓性材料から成り、例えば内側がゴムコーティングされたナイロン布を袋状に形成したものから構成されている。 Is made of a non-breathable flexible material, for example nylon cloth inside it is rubber coated consists those formed in a bag shape. またエアバッグ1の背面側2の中央部にはガス流入孔3が形成されている。 Also in the central portion of the rear side 2 of the airbag 1 is formed with a gas inlet hole 3.

【0009】上述のエアバッグ1は、自動車室内の乗員の前方に折り畳まれた状態で配置される。 [0009] Air bag 1 described above are arranged in a folded state in front of the vehicle occupants chamber. 例えば、図には示していないが、車室内の運転席前方に位置するステアリングホイールの中央ハブ部に設けられた支持プレートにインフレータが配置され、エアバッグ1は、そのガス流入孔3がこのインフレータに嵌合した状態で、該ガス流入孔3の周辺部分が上記支持プレートに固定される。 For example, although not shown, the inflator is disposed on the support plate provided in the central hub portion of a steering wheel located in front of the driver's seat in the vehicle compartment, the air bag 1, whose gas inlet hole 3 the inflator in fitted state, the peripheral portion of the gas inlet hole 3 is fixed to the support plate. かかるエアバッグ1は、折り畳まれた状態で、支持プレートに取付けられたカバー内に収納される。 Such airbag 1 is in the folded state, it is accommodated in a cover which is attached to the support plate.

【0010】このようなエアバッグ1の取付構成は、例えば実開平1−150155号公報などに詳しく記載されているように、従来より周知であるため、これ以上の説明は省略する。 [0010] mounting structure of the airbag 1, for example as described in detail such as in real-Open 1-150155, JP-because it is well known from the prior art, it will not be described further.

【0011】本発明に係るエアバッグシステムは、上述のエアバッグ1、及びインフレータのほかに、車体の適所に配置されたセンサ(図示せず)を有しており、このセンサが自動車の衝突を検知すると、その検知信号により上記インフレータが作動して例えば窒素ガスを発生する。 [0011] Air bag system according to the present invention, the air bag 1 described above, and in addition to the inflator, has a sensor located on the vehicle body of the place (not shown), the crash sensor is an automobile Upon detection, the inflator to generate a working example, nitrogen gas by the detection signal. このようにして発生したガスは図1に示したガス流入孔3からエアバッグ1内に送り込まれ、これによってエアバッグ1が膨張を開始し、その圧力で、エアバッグ1を取り囲んだ前述のカバーを破断する。 Thus gas generated by the fed from the gas inlet hole 3 shown in FIG. 1 the air bag 1, whereby the airbag 1 starts to expand, its pressure, the aforementioned cover surrounding the airbag 1 the break. 次いでエアバッグ1は、ステアリングホイールと乗員との間で大きく膨張し、その表面側4で乗員の体、特にその顔面を受け止め、乗員を保護する。 Then the air bag 1 is largely inflated between the steering wheel and the occupant, the occupant's body in the front side 4, in particular receiving the face to protect the occupant.

【0012】膨張したエアバッグ1が乗員を受け止めたとき、乗員に対する衝撃を緩和する目的で、エアバッグ1内のガスの一部を排出させる必要がある。 [0012] When the inflated airbag 1 has been the occupants, in order to cushion the impact against the passenger, it is necessary to discharge a portion of the gas in the airbag 1. このため、 For this reason,
本発明においては、図1乃至図3に例示するように、エアバッグ1の背面側2に、適数の、図の例では4個の貫通孔5が形成され、これらの貫通孔5に、例えばゴム又は軟質合成樹脂より成るシート状の弾性部材6が設けられている。 In the present invention, as illustrated in FIGS. 1 to 3, the rear side 2 of the airbag 1, the appropriate number, in the example of FIG formed four through holes 5, in the through holes 5, for example, a sheet-like elastic member 6 made of rubber or soft synthetic resin are provided. すなわち、弾性部材6の周辺が、貫通孔5のまわりのエアバッグ部分に、例えば縫製又は接着剤などによって固定され、貫通孔5が弾性部材6によって覆われているのである。 That is, the periphery of the elastic member 6, the air bag portion around the through-hole 5, for example, is secured such as by sewing or adhesive, the through-hole 5 is what is covered by the elastic member 6. 符号8はその縫製部分を示している。 Reference numeral 8 denotes the sewing portion. 各弾性部材6には、エアバッグ1の内部のガスを排出させる適数の排気孔7が形成されている。 Each elastic member 6, the exhaust hole 7 of the appropriate number of discharging the gas inside the air bag 1 is formed.

【0013】前述のようにエアバッグ1は、その内部にガスが送り込まれることによって膨張するが、このときのエアバッグ内の圧力変化の一例を図4に示す。 [0013] Air bag 1 as described above is inflated by the gas is fed therein, illustrating an example of the pressure change in the air bag in this case is shown in FIG. 4. 図4は縦細にエアバッグ内の圧力をとり、横軸に時間をとったグラフであり、実線Aが図1乃至図3に示したエアバッグ1の内圧変化を示している。 Figure 4 takes the pressure in the air bag TateHoso a graph plotting the time on the horizontal axis, the solid line A indicates the change in internal pressure of the air bag 1 shown in FIGS.

【0014】図4において、t 1の時点でエアバッグ1 [0014] In FIG. 4, the air bag 1 at the time of t 1
の内部の圧力はピーク値P 1を示すが、これはガスを送り込まれたエアバッグ1が前述のようにカバーを破断するときの圧力である。 Internal pressure of exhibits a peak value P 1, which is the pressure at which the air bag 1 sent into the gas to break the cover as described above. カバーを破断した後、エアバッグ内の圧力は一旦低下するが、内部に送り込まれたガスの量が増大するに従って、エアバッグ内の圧力は再び上昇し、t 2で示す時点で最大値P 2となり、エアバッグ1の膨張を完了する。 After breaking the cover, the pressure in the airbag is reduced once, according to the amount of gas fed into the inside is increased, the pressure in the airbag is increased again, the maximum value P 2 at the time indicated by t 2 next, to complete the expansion of the air bag 1.

【0015】カバーの破断後にエアバッグ1内の圧力が再び上昇するとき、このエアバッグ1と弾性部材6には引張力が加わるようになり、その大きさはエアバッグ1 [0015] When the pressure in the airbag 1 after rupture of the cover is raised again, this would be a tensile force is applied to the airbag 1 and the elastic member 6, the size of the air bag 1
の膨張に伴って増大する。 It increases with the expansion. かかる引張力が作用したとき、エアバッグ自体は前述のようにゴムコーティングされた布から成るため、大きく引張変形することはないが、弾性部材6はゴムなどの弾性材料より成るので、エアバッグ1内の圧力の上昇に伴って該弾性部材6は引張変形し、内部の圧力がt 2の時点で最大値P 2に達したとき、弾性部材6は図5及び図6に示すように大きく弾性変形する。 When such tension is applied, since it made of fabric airbag itself which is rubber coated as described above, but is not possible to increase tensile deformation, the elastic member 6 is made of an elastic material such as rubber, the airbag 1 increased elastic member 6 is tensile deformation along with the pressure of the inner, when the internal pressure reaches the maximum value P 2 at time t 2, as the elastic member 6 shown in FIGS. 5 and 6 increased elasticity Deform. このため、弾性部材6に形成された排気孔7 Therefore, the exhaust hole 7 formed in the elastic member 6
の大きさも図5及び図6に示したように大きく拡大する。 The size is also greatly expanded, as shown in FIGS. 5 and 6. 図6における矢印はエアバッグ内の圧力を示している。 The arrows in Figure 6 shows the pressure in the airbag.

【0016】上述のように、エアバッグ1がカバーを切断した直後の段階では、排気孔7の大きさは小さく留められているが、その後エアバッグ1が膨張を続け、その内圧が最大値P 2に達する直前のあたりで排気孔7は大きく拡大する。 [0016] As described above, at the stage immediately after the airbag 1 has cut the cover, the size of the exhaust hole 7 is fastened small, then continued airbag 1 is expanded, the maximum value P that internal pressure exhaust hole 7 around just before reaching 2 is greatly expanded. その際、この膨張が始まった初期の段階では、上述のように排気孔7の大きさは小さいため、ここから流出するガスの量は極く少ないものとなる。 At that time, in this expansion began early stage, since the size of the exhaust hole 7 as described above is small, the amount of gas flowing out here becomes very small. 従って、エアバッグ1は迅速に膨張し、極く短時間でその膨張を完了する。 Therefore, the airbag 1 is rapidly expanded, completes its expansion in an extremely short time. よって、かかるエアバッグ1によって確実に乗員を受け止めることができる。 Therefore, it is possible to receive reliably occupant by such an air bag 1.

【0017】一方、エアバッグ1の膨張が進み、その内圧が最大値P 2に達する直前のあたりで排気孔7は大きく拡大するので、ここを通してエアバッグ1の内部からの流出するガスの量が増大する。 Meanwhile, it advances the inflation of the airbag 1, since the inner pressure to expand the exhaust hole 7 is larger around just before reaching the maximum value P 2, the amount of outflowing gas from the interior of the airbag 1 through here increased. このため、乗員が膨張を完了したエアバッグ1に当ったとき、エアバッグ1の内部の圧力が高すぎてしまうようなことはなく、また乗員がエアバッグ1に当った後も、その内部のガスが拡大した排気孔7を通して効果的に放出されるので、乗員への衝撃を確実に緩和することができる。 Therefore, when the hit the airbag 1 the occupant has completed the inflation, never as excessively high internal pressure of the airbag 1, also after the occupant hits the airbag 1, the internal since the gas is effectively released through the exhaust hole 7 is an enlarged, it is possible to reliably reduce an impact to the occupant.

【0018】上述のように、エアバッグ1からのガスの排出量が、その内部のガス圧の上昇に応じて増大するので、エアバッグ1の膨張を迅速に完了し、かつエアバッグ1の乗員に対する衝撃を効果的に和らげることができるのである。 [0018] As described above, emissions of gas from the airbag 1, since increases in response to an increase in the internal gas pressure rapidly complete the inflation of the airbag 1, and the occupant of the airbag 1 impact it is possible to effectively relieve against.

【0019】図2及び図3に示した実施例では、エアバッグ1内にガスが送り込まれる前の状態において、弾性部材6が外側に突出するように、該弾性部材6を形成したが、図7に示すように、エアバッグ1が膨張する前の状態で、弾性部材6がエアバッグ1とほぼ面一となるように、弾性部材6に形成してもよい。 [0019] In the embodiment shown in FIGS. 2 and 3, in a state before the gas is fed into the airbag 1, so that the elastic member 6 projecting outwardly has formed the elastic member 6, FIG. as shown in 7, in a state before the airbag 1 is inflated, so that the elastic member 6 is substantially flush with the airbag 1 may be formed on the elastic member 6. このように弾性部材6の形態は適宜選択することができる。 The form of an elastic member 6 so may be appropriately selected.

【0020】 [0020]

【発明の効果】請求項1に記載の構成によれば、エアバッグを迅速に膨張させ、かつこのエアバッグによって乗員を受け止めたとき、乗員に与える衝撃を効果的に緩和することができ、しかもそのエアバッグシステムの構造は簡単で、従来よりもコストを低減できる利点が得られる。 Effects of the Invention] According to the arrangement of claim 1, rapidly inflate the air bag, and when the occupants by the air bag, it is possible to effectively mitigate the impact on the occupant, moreover its structure of an airbag system is simple, the advantage of reducing the cost of traditional is obtained.
