(For example, see Patent Document 1)
即ち、図1〜図5において、内装パネル10には、図示しないレーザ発生手段からパルス状に発生するレーザを、内装パネル10の裏面側からその裏面に固着する一対の補強部材11,11の外形縁部に沿って相対移動しながら照射することにより、内装パネル10の裏面に対して直角方向に穿ち形成された長尺方向の前,後ヒンジ溝10aと中央破断溝10b及び短尺方向の破断溝10cを設けることで、エアーバッグ12を収容するエアーバッグケース13の開口13aの大きさに対応するエアーバッグ膨張展開用の前,後破断開放部14a,14bからなる破断開放部14が形成されていると共に、前記破断開放部14の周辺領域に対応する周囲位置の裏面に密着する補強縁部15cを有する枠体15とが配設されている。 That is, in FIGS. 1 to 5, the exterior of the pair of reinforcing members 11, 11 for fixing a laser generated in a pulse form from a laser generating means (not shown) from the back side of the interior panel 10 to the back surface of the interior panel 10. By irradiating while moving relatively along the edge, the longitudinal front and rear hinge grooves 10a, the central breaking groove 10b, and the short breaking groove formed in a direction perpendicular to the back surface of the interior panel 10 are formed. By providing 10c, a break open portion 14 consisting of front and rear break open portions 14a and 14b for inflating and deploying an air bag corresponding to the size of the opening 13a of the air bag case 13 that accommodates the air bag 12 is formed. In addition, a frame body 15 having a reinforcing edge portion 15 c that is in close contact with the back surface of the peripheral position corresponding to the peripheral region of the fracture opening portion 14 is disposed.
また、前記破断開放部14は、長尺方向及びそれと直角方向に形成した中央破断溝10b,短尺の左右破断溝10c,10cによって、前,後破断開放部14a,14bとなり、エアーバッグ膨張展開時に、それぞれ、前記前,後ヒンジ溝10a,10aを介して観音開き状態に破断開口される構成になっている。 Further, the break open portion 14 is formed into a front and rear break open portions 14a and 14b by a central break groove 10b and short left and right break grooves 10c and 10c formed in the long direction and in a direction perpendicular to the long direction. These are configured to be opened in a double-spread state through the front and rear hinge grooves 10a and 10a, respectively.
前記内装パネル10の破断開放部14は、エアーバッグ膨張展開時にエアーバッグ12の展開圧力により開放される際、前記前,後ヒンジ溝10aが前記内装パネル10より切り離されてしまう場合がある。そのため、前記内装パネル10の前記破断開放部14の裏面には、前記一対の補強部材11,11の一端水平部11a,11aが溶着等の手段により固着され、その各他端となる鉛直部11b,11bが、ヒンジ部11c,11cを介して折り曲げられて垂下され、この各鉛直部11b,11bを、前記エアーバッグケース13の開口部13aの外周寸法より僅かに大きな内周寸法を有するようにして前記内装パネル10の裏面側に、一体成形された枠体15の前,後壁15a,15bに所定の間隔で並列に形成された角穴15dと、前記補強部材11,11の各他端の鉛直部11b,11bに前記枠体15の角穴15dと対応して形成された複数のフック係止用角穴11dに対し、前記ケース13の前,後壁面13b,13bに取り付けられたフック部17を係止する構成とすることで、エアーバッグ膨張展開時に観音開きされた内装パネル10の破断開放部14が飛散しないようにしたものである。 When the break open part 14 of the interior panel 10 is opened by the deployment pressure of the airbag 12 when the airbag is inflated and deployed, the front and rear hinge grooves 10a may be separated from the interior panel 10. Therefore, one end horizontal portions 11a and 11a of the pair of reinforcing members 11 and 11 are fixed to the back surface of the fracture opening portion 14 of the interior panel 10 by means such as welding, and the vertical portion 11b serving as the other end thereof. , 11b are bent and suspended via hinges 11c, 11c so that the vertical portions 11b, 11b have an inner peripheral dimension slightly larger than the outer peripheral dimension of the opening 13a of the airbag case 13. In addition, square holes 15d formed in parallel at predetermined intervals on the front and rear walls 15a and 15b of the integrally formed frame 15 on the back side of the interior panel 10, and the other ends of the reinforcing members 11 and 11, respectively. Are attached to the front and rear wall surfaces 13b, 13b of the case 13 with respect to a plurality of hook locking square holes 11d formed in the vertical portions 11b, 11b corresponding to the square holes 15d of the frame body 15, respectively. Was In the structure for engaging the hook portion 17, in which fracture-opening section 14 of the interior panel 10 which is double doors when the airbag inflation and deployment is to avoid splashing.
なお、前記前,後破断開放部14a,14bの開放を阻害しないようにするため、前記一対の補強部材11,11の各他端の鉛直部11b,11bのフック係止用角穴11d,11dは大きめに設定されており、前記前,後破断開放部14a,14bの開放と共に、前記各鉛直部11b,11bの上方への移動を可能にし、エアーバッグ膨張展開時の展開圧力を吸収できるようにしている。
また、前述した図3に示すように、前記枠体15の鉛直内壁面15aには所定の間隔で蟻溝18が形成されており、この蟻溝18と前記補強部材11の鉛直外壁面11b,11bに前記蟻溝18と対応させて形成した楔状の突起部19が契合されることで、エアーバッグ膨張展開時において、前記一対の補強部材11,11に溶着された破断開放部14が容易に飛散することのないようにしたものである。
In order not to obstruct the opening of the front and rear break open portions 14a, 14b, the hook engaging square holes 11d, 11d of the vertical portions 11b, 11b at the other ends of the pair of reinforcing members 11, 11 are used. Is set to a large size so that the front and rear break open portions 14a and 14b can be opened and the vertical portions 11b and 11b can be moved upward to absorb the deployment pressure when the airbag is inflated and deployed. I have to.
Further, as shown in FIG. 3 described above, dovetail grooves 18 are formed at predetermined intervals on the vertical inner wall surface 15a of the frame body 15, and the dovetail grooves 18 and the vertical outer wall surfaces 11b of the reinforcing member 11 are formed. When the wedge-shaped protrusion 19 formed in correspondence with the dovetail groove 18 is engaged with 11b, the break open portion 14 welded to the pair of reinforcing members 11 and 11 can be easily formed during inflation and deployment of the airbag. It is designed not to be scattered.
上記のように構成された自動車用エアーバッグ装置においては、車両が衝突した際には、その衝突時の衝撃力をセンサで検出し、このセンサで検出した衝撃力が予め定めた値以上になった否かをCPU等からなる制御装置で判定し、設定値以上と判定された時に制御装置から出力される信号によりインフレータを動作させて所定のガスを発生させ、このガスをエアーバッグに供給することにより、エアーバッグを急速に膨張展開させる。 In the automotive airbag device configured as described above, when a vehicle collides, the impact force at the time of the collision is detected by a sensor, and the impact force detected by this sensor becomes a predetermined value or more. A control device comprising a CPU or the like, and when it is determined that the value is equal to or greater than a set value, the inflator is operated by a signal output from the control device to generate a predetermined gas, and this gas is supplied to the airbag. As a result, the airbag is rapidly inflated and deployed.
すなわち、エアーバッグが膨張展開することにより、その圧力で内装パネル10の破断開放部14が内側から押圧されると、破断開放部14の中央破断溝10b及び短尺方向の破断溝10cが破断され、前,後ヒンジ溝10aを介して観音開き状態に展開される。そして、観音開き状態に展開された前,後破断開放部14a,14bは各補強部材11,11のそれぞれのヒンジ部11c,11cを介して展開される。
これと同時に、エアーバッグ12は開かれた破断開放部14から内装パネル10の外方へ膨張展開され、この膨張展開されたエアーバッグ12の緩衝作用で、助手席の乗員の頭部或いは 胸部等を支えることにより、乗員を車両衝突時の衝撃力から保護するようにしている。
At the same time, the air bag 12 is inflated and deployed from the opened break opening portion 14 to the outside of the interior panel 10, and the cushioning action of the inflated and deployed air bag 12 allows the passenger's head or chest of the passenger seat, etc. By supporting the occupant, the occupant is protected from the impact force at the time of the vehicle collision.
ところで、上記の自動車用エアーバッグ装置においては、内装パネルの破断開放部の裏面に溶着される一対の補強部材は互いに分離された単品部品として形成され、各補強部材はそれぞれ枠体に蟻溝結合状態に装着されるようになっている。
したがって、前記補強部材の枠体への蟻溝結合及び破断開放部裏面への溶着などの作業性が悪く製品が高価となる。
また、前記補強部材の構成が前記破断開放部裏面への溶着のための水平対応面と補強枠体の鉛直周壁面と結合する鉛直壁面を有するほぼ逆L字状をなす単品構成であるため、型成型時に同一型を複数用意するため型代が嵩み、エアーバッグ12の膨張展開時に発生する衝撃力に対して弱く、破断開放部の左右表面部にササクレ現象が発生したり、表皮が伸びて完全に切断されずに接続状態になったままとなったり、外観の見栄えが悪くなる問題点がある。
By the way, in the above-described automotive airbag device, the pair of reinforcing members welded to the back surface of the fracture opening portion of the interior panel is formed as a single component separated from each other, and each reinforcing member is connected to the frame by a dovetail groove. It comes to be attached to the state.
Therefore, workability such as dovetail bonding to the frame of the reinforcing member and welding to the rear surface of the fracture opening portion is poor and the product is expensive.
In addition, since the configuration of the reinforcing member is a single product configuration having a substantially inverted L shape having a horizontal corresponding surface for welding to the rear surface of the fracture opening portion and a vertical wall surface coupled to the vertical peripheral wall surface of the reinforcing frame, Since the same mold is prepared at the time of mold molding, the mold cost is increased, it is weak against the impact force generated when the airbag 12 is inflated and deployed, and the phenomenon of sacrificial phenomenon occurs on the left and right surface parts of the break opening part, and the skin extends. There is a problem that the connected state is not completely disconnected and the appearance is not good.
本発明は、上記のような従来の課題を解決するためになされたもので、本発明の目的は、車両の内側フロント部や側柱部、ハンドル中央部等を覆う内装パネルの破断開放部及びその外周縁近傍の外方からの押圧負荷に対する耐圧性を向上できると共に、内装パネルの破断開放部の裏面に溶着される補強部材を内装パネル材料と同系の熱可塑性プラスチック材料で形成することで、内装パネルと補強部材との接合を振動溶着によって行なうことができるとともに、前記補強部材を矩形筒状の一体成形とし、かつ前記破断開放部の裏面と溶着する水平対応面を四方に分離区画して形成し、各分離区画する互いに対応する貫通溝の一部に薄肉部で構成した結合部を設けた構成とすることで、前記補強部材の全体強度を向上させ、前記補強部材と枠体との組み付けを容易にする。また、破断開放部が四分割状態に開放するため片開き方式或いは観音開き方式に比べ開放速度が速くなる四分割破断構成の自動車用エアーバッグ装置を提供することにある。 The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a break open portion of an interior panel that covers an inner front portion, a side pillar portion, a handle central portion, and the like of a vehicle, and By improving the pressure resistance against the pressure load from the outside in the vicinity of the outer peripheral edge, and forming the reinforcing member welded to the back surface of the fracture opening portion of the interior panel with a thermoplastic material similar to the interior panel material, The interior panel and the reinforcing member can be joined by vibration welding, the reinforcing member is integrally formed in a rectangular cylindrical shape, and a horizontal corresponding surface that is welded to the back surface of the fracture opening portion is divided into four sections.

以上のように構成された本発明の第1実施形態による助手席用のエアーバッグ装置によれば、自動車などの車両が衝突した際には、その衝突時の衝撃力を図示省略した周知のセンサで検出し、このセンサで検出した衝撃力が予め定めた値以上になった否かを図示省略した周知のCPU等からなる制御装置で判定し、設定値以上と判定された時に制御装置から出力される信号により、図示省略した周知のインフレータを動作させて所定のガスを発生させ、このガスをエアーバッグ43に供給することにより、エアーバッグ43を急速に膨張展開させる(図10参照)。 According to the airbag apparatus for a passenger seat according to the first embodiment of the present invention configured as described above, when a vehicle such as an automobile collides, a well-known sensor in which the impact force at the time of the collision is not shown in the figure. The controller determines whether or not the impact force detected by this sensor is equal to or greater than a predetermined value by a control device such as a well-known CPU (not shown) and outputs from the control device when it is determined to be equal to or greater than the set value. In response to this signal, a known inflator (not shown) is operated to generate a predetermined gas, and this gas is supplied to the airbag 43, whereby the airbag 43 is rapidly inflated and deployed (see FIG. 10).
エアーバッグ43が膨張展開する場合、エアーバッグ43の膨張展開初期時に発生する圧力が補強部材47の水平面にかかると、この補強部材47の水平対応面47a〜47dに溶着された破断開放部46a〜46dは中央破断用溝30bの脆弱部分から半円破断用溝30dの脆弱部分に沿い順次破断されると共に、この前,後の破断開放部46a,46bを含む補強部材47の水平対応面はヒンジとなる折曲部を支点にして図9に示すように展開されるが、この状態では前記枠体45の蟻溝52に結合された補強部材47の係合突出部51が僅かに上方に移動可能となるため、両者の蟻溝結合部で折曲部の展開初期圧力を吸収し、展開最終段階では前記枠体45の角穴54の開口ギャップによっても前記圧力を吸収できることで、内装パネル30の開口周縁に発生する損傷が防止でき、図9に示すようにスムーズに観音開き状態に外側へ展開される。 When the airbag 43 is inflated and deployed, if the pressure generated at the initial stage of inflation and deployment of the airbag 43 is applied to the horizontal surface of the reinforcing member 47, the fracture opening portions 46a to 46a welded to the horizontal corresponding surfaces 47a to 47d of the reinforcing member 47. 46d is sequentially broken from the weak part of the central breaking groove 30b to the weak part of the semicircular breaking groove 30d, and the horizontal corresponding surface of the reinforcing member 47 including the front and rear break opening parts 46a and 46b is a hinge. 9 is developed with the bent portion as a fulcrum as a fulcrum. In this state, the engagement protrusion 51 of the reinforcing member 47 coupled to the dovetail groove 52 of the frame 45 moves slightly upward. Therefore, the expansion initial pressure of the bent portion is absorbed by the joint portion of both the dovetail grooves, and the pressure can also be absorbed by the opening gap of the square hole 54 of the frame body 45 in the final expansion stage. It prevents damage occurring to the 30 periphery of the opening of is expanded outward smoothly double doors state as shown in FIG.
また、この発明においては、枠体45と補強部材47との蟻溝結合及び補強部材47の水平対応部47a〜47dからヒンジとなる折曲部を介して連続する周壁面47eに形成した角穴55の開口部の下端を、枠体45の角穴54開口部の下端より下方になるように大きくすることによってヒンジ伸び代を確保できるため、前,後の破断開放部46a,46bと補強部材47の水平対応部47a〜47dとの溶着部に与える衝撃力を解消できる。 In the present invention, the dovetail coupling between the frame body 45 and the reinforcing member 47 and the square hole formed in the peripheral wall surface 47e that continues from the horizontal corresponding portions 47a to 47d of the reinforcing member 47 through the bent portion serving as a hinge. Since the extension of the hinge can be secured by enlarging the lower end of the opening of 55 so as to be lower than the lower end of the opening of the square hole 54 of the frame 45, the front and rear break opening portions 46a and 46b and the reinforcing member The impact force applied to the welded part with the 47 horizontal corresponding parts 47a to 47d can be eliminated.
さらに、この第1実施形態によれば、破断開放部46の前後左右の開口周辺領域は枠体45の補強縁部45aに溶着されているため、破断開放部46の開放動作に追従することが抑制され中央破断用溝30b及び半円破断用溝30dで速やかに破断されることになり、エアーバッグ43の膨張展開時に破断された破断開放部46a〜46dの破断面にシャープなエッジが生じたり、破断部にささくれ現象が生じるのを予防し、綺麗な破断面を提供できる。 Furthermore, according to the first embodiment, the front and rear, left and right opening peripheral regions of the break opening part 46 are welded to the reinforcing edge 45a of the frame body 45, so that the opening operation of the break opening part 46 can be followed. It will be ruptured quickly by the central breaking groove 30b and the semi-circular breaking groove 30d, and a sharp edge may be generated on the fracture surfaces of the fracture opening portions 46a to 46d broken when the airbag 43 is inflated and deployed. It is possible to prevent the occurrence of a whirling phenomenon at the fracture portion and provide a beautiful fracture surface.
さらに、破断開放部46のヒンジ溝30a,破断用溝30cに沿う開口周辺領域は枠体45の補強縁部45aにより補強されているため、破断開放部46を含む内装パネル30の上方からの押圧力に対して耐圧性が増し、エアーバッグ装置の不使用時における内装パネル30の割れ,歪み等の変形を防止できる。 Further, since the opening peripheral region along the hinge groove 30a and the breaking groove 30c of the break opening part 46 is reinforced by the reinforcing edge 45a of the frame body 45, the inner panel 30 including the break opening part 46 is pushed from above. The pressure resistance increases with respect to the pressure, and it is possible to prevent deformation of the interior panel 30 such as cracking and distortion when the airbag apparatus is not used.

Since it becomes possible to perform vibration welding through the protrusions 53 of the streaks formed on each horizontal plane and the reinforcing edge, welding work is easy.
更に、前記第1実施形態では前記枠体45を高弾性の熱可塑性樹脂で、且つ補強部材47を低弾性の熱可塑性樹脂で成形したものについて説明したが、前記枠体45及び補強部材47を共に低弾性の熱可塑性樹脂或いは共に高弾性の熱可塑性樹脂で、更には枠体45を低弾性の熱可塑性樹脂で、補強部材を高弾性の熱可塑性樹脂で形成するなどしてもよい。 Furthermore, although the said 1st Embodiment demonstrated what shape | molded the said frame 45 with the highly elastic thermoplastic resin and the reinforcement member 47 with the low elastic thermoplastic resin, the said frame 45 and the reinforcement member 47 were demonstrated. Both the low elastic thermoplastic resin or the high elastic thermoplastic resin may be used. Further, the frame body 45 may be formed of a low elastic thermoplastic resin, and the reinforcing member may be formed of a high elastic thermoplastic resin.
また、エアーバッグケース44は枠体45および補強部材47に対して分離可能に結合できる構成になっているため、廃車時などにエアーバッグケース44を枠体45から容易に取り外すことができ、産業廃棄物となるインフレータなどの関連部品を容易に分離除去でき、環境に悪影響を与えることが防止できる。 Further, since the airbag case 44 is configured to be separably coupled to the frame body 45 and the reinforcing member 47, the airbag case 44 can be easily detached from the frame body 45 when the vehicle is scrapped. It is possible to easily separate and remove related parts such as inflators that become waste, and to prevent adverse effects on the environment.
本発明における自動車用エアーバッグ装置における第1実施例にあっては、内装パネルを3層の積層板を用いたものについて説明したが,これに限定されることなく単板状の内装パネルであっても、また基板の上面にフォーム層を除いて表皮層のみを接合して形成した2層構造の内装パネルであっても同様に構成できることは勿論である。また、前記内装パネルの裏面側よりレーザ加工する破断溝の深さは、合成樹脂製の基板と前記基板の表面に積層接着された表皮層とから構成されたものにあっては、前記基板の裏面側より前記基板の厚さを貫通するのみの加工に止め、表皮層部分にはレーザ加工をしないことで、表皮層に引けなどの外観を損ねる問題を解消できる。 In the first embodiment of the automobile air bag apparatus according to the present invention, the interior panel has been described using a three-layer laminate. However, the interior panel is not limited to this and is a single-plate interior panel. Of course, an interior panel having a two-layer structure formed by bonding only the skin layer except for the foam layer on the upper surface of the substrate can be configured in the same manner. In addition, the depth of the fracture groove to be laser-processed from the back side of the interior panel is composed of a synthetic resin substrate and a skin layer laminated and adhered to the surface of the substrate. By stopping the processing only through the thickness of the substrate from the back side and not performing laser processing on the skin layer portion, it is possible to solve the problem of damaging the appearance such as the surface layer.
