【０００６】[0006]
前述（1）〜（11）の手段についてそれぞれの作用を順次説明する。（1）エア バッグ装置用衝突衝撃感知器としての円筒形直線運動重錘について説明する。従 来のエアバッグ装置に用いられる車両衝突時の衝撃感知重錘としては、断面が長 方形の角柱を用い、角柱自体で案内の役割も果たす形式の重錘が採用されている 。このような形式の重錘を採用することは、重錘の衝撃感知機能および加工精度 確保の面で問題がある。本考案における請求項１に示される２点支持直進式円筒 形衝撃感知重錘はこの問題点を解決するものである。本重錘の実施例を示す図１ によって説明する。 The operation of each of the means (1) to (11) will be sequentially described. (1) A cylindrical linear motion weight as a collision impact sensor for an airbag device will be described. As a shock-sensing weight for a vehicle collision used in a conventional air bag device, a prism having a rectangular cross section is used, and a weight that also serves as a guide by the prism itself is adopted. Adopting such a type of weight has problems in terms of impact detection function of the weight and securing of processing accuracy. The two-point-supporting straight-traveling cylindrical impact-sensing weight according to claim 1 of the present invention solves this problem. An example of the main weight will be described with reference to FIG.
【０００７】 円筒形重錘は図１に示されるように、同軸心の前部円筒１と後部円筒２がそれ ぞれ前部重錘受３および後部重錘受４により支持される。一方重錘胴部６は断面 形状については制約はないものの、加工を考えれば円筒形が望ましく、図１のよ うに円筒形状を採れば重錘の加工が極めて容易となり、重錘円筒精度および表面 粗さが向上され、慣性重錘の製作・取付面で、また作動面で利点を得る。 さらに後部円筒前端と後部重錘受４の間にスペ−サすなわちがた・隙間排除用 リング５を置くことにより慣性重錘の位置決めを行うことができる。又、前部円 筒前端部を円筒形楔７とし、本エアバッグ装置の中枢機能である、重錘の衝突の 際生じる衝撃慣性力伝達の役割を確保すると同時に、ガスボンベ開封用ハンマ− ばね力の加わっている衝撃慣性力伝達リンク８と円筒形楔７との間の接触圧によ り、慣性重錘の設置姿勢を自然に決めることができる。 このように本２点支持直進式円筒形衝突衝撃感知用慣性重錘は多くの特長と利 点を兼ね備えており、エアバッグ装置に最適のものである。In the cylindrical weight, as shown in FIG. 1, a front cylinder 1 and a rear cylinder 2 which are coaxial with each other are supported by a front weight receiver 3 and a rear weight receiver 4, respectively. On the other hand, although the cross-sectional shape of the weight body 6 is not limited, a cylindrical shape is preferable in consideration of processing. If the cylindrical shape is adopted as shown in Fig. 1, processing of the weight becomes extremely easy. Roughness is improved, and it has advantages in manufacturing and mounting surface of inertial weight and in operating surface. Further, by placing a spacer, that is, a rattling / clearance eliminating ring 5 between the front end of the rear cylinder and the rear weight receiver 4, the inertial weight can be positioned. In addition, the front end of the front cylinder is a cylindrical wedge 7 to secure the role of transmitting the impact inertial force generated at the time of collision of the weight, which is the central function of this airbag device, and at the same time, the hammer spring force for opening the gas cylinder. Due to the contact pressure between the impact inertial force transmission link 8 and the cylindrical wedge 7, the installation posture of the inertial weight can be naturally determined. As described above, the two-point supporting straight-moving cylindrical collision impact sensing inertia weight has many features and advantages, and is optimal for an airbag device.
【０００８】 （2）ハンマー軸と解錠レバー軸連結支持装置の作用について説明する。解錠 レバ−即ち衝撃慣性力伝達リンクが作動しガスボンベ開封用ハンマ−が解錠され ると、ハンマ−の一部を構成するカムが開封穿孔ピン即ち円筒楔形金具を押して ガスボンベが開封される。この時カムと穿孔ピン頭部間には、ハンマ−駆動ばね の持つガスボンベ開封のためのねじりモ−メントＭspによって、接触面に垂直な 力Ｐと接触面接線摩擦力μＰが生じる。ここにμは摩擦係数である。ハンマ−が 解錠されたとき、ばねの持つエネルギ−はガスボンベの開封および開封穿孔ピン の加速に使われる。いま、ばねのねじりモ−メントが穿孔ピンの抵抗力と釣りあ うとすれば、円弧形偏心カムを用いて半球形頭部を持つ穿孔ピンを駆動するとし て、これらの接触状態を示す 図２ を参照すれば、接触面垂直荷重Ｐは 数１ に より与えられる。試作エアバッグ装置においては、ばねのねじりモ−メントが全 部ここでＰに変換されるとすれば、このＰは3000Ｎを超える大きい力となるが、 穿孔ピンの先端の形状は円筒楔形としているため、ガスボンベの開封は局部的で 、急速にではあるが形式的には徐々に進行するので、ボンベ密封金属箔のせん断 穿孔抵抗はほぼ 250Ｎであり、したがって残りのエネルギはピンの加速やここで 取り上げていない摩擦損失として消費される。しかしいずれにしても、ガスボン ベ開封に際しては、ばねのねじりモ−メントの大きさから衝撃的挙動となりハン マ−軸に極めて大きな衝撃力が生じる。このような理由から、エアバッグ装置の 作動を安定にしてかつ確実なものとする必要性から、この目的のために請求項２ に記述のハンマ−軸と解錠レバ−軸間に軸剛性を確保するための軸剛性保持金具 の設置が不可欠である。(2) The operation of the hammer shaft and the unlocking lever shaft connecting and supporting device will be described. When the unlocking lever, that is, the impact inertial force transmission link is actuated and the hammer for opening the gas cylinder is unlocked, the cam forming a part of the hammer pushes the opening perforation pin, that is, the cylindrical wedge-shaped metal fitting to open the gas cylinder. At this time, a force P perpendicular to the contact surface and a tangential frictional force μP to the contact surface are generated between the cam and the head of the boring pin due to the torsional moment Msp of the hammer driving spring for opening the gas cylinder. Where μ is the coefficient of friction. When the hammer is unlocked, the energy of the spring is used to open the gas cylinder and accelerate the opening piercing pin. Now, assuming that the torsional moment of the spring balances the resistance of the piercing pin, it is assumed that the eccentric cam with an arc shape is used to drive the piercing pin with a hemispherical head and the contact state between them is shown. Referring to 2, the contact surface vertical load P is given by In the prototype airbag device, if all the torsional moment of the spring is converted into P here, this P becomes a large force exceeding 3000 N, but the shape of the tip of the piercing pin is a cylindrical wedge shape. Therefore, since the opening of the gas cylinder is local and progresses rapidly but formally gradually, the shear perforation resistance of the metal foil sealing the cylinder is approximately 250 N, so the remaining energy is the acceleration of the pin or here. It is consumed as friction loss not mentioned. However, in any case, when the gas cylinder is opened, the torsional moment of the spring causes a shocking behavior, and an extremely large impact force is generated on the hammer shaft. For this reason, it is necessary to make the operation of the airbag device stable and reliable, and for this purpose, axial rigidity is set between the hammer shaft and the unlocking lever shaft described in claim 2. It is indispensable to install a shaft rigidity holding fitting to secure it.

【０００９】 （3）円筒楔形ガスボンベ開封穿孔ピンの作用について説明する。エアバッグ 装置の作動は千分の一秒を争い、この面からその性能を左右するものの一つにガ スボンベ開封用穿孔金具が挙げられる。請求項３に挙げられる偏心中空円筒式円 筒楔形穿孔金具はこの要請に応える性能の穿孔金具である。 図３ に本考案にな る円筒楔形金具９がガスボンベ１２の密封金属箔１１を穿孔し開封しようとする 過程にあるところを示す。円筒楔形金具９即ち穿孔ピンには図３に示されるよう に中空円筒が円筒本体に偏心して穴明けされている。この偏心によって楔が密封 金属箔１１を突き破ってガスボンベ１２の内部とエアバッグとをガス短絡路１０ によって連絡し、ガスの流出時点を早め、さらにすり割り１３あるいはガス流出 口を円筒楔形金具９本体に設けることにより、ガス短絡路面積を大きくし、ガス のエアバッグ充填時間を短縮する。ガスボンベ開封金具の穿孔部に円筒楔形を採 用し、ガス短絡流出口を設けることによって初めて以上の特性が得られ、他の穿 孔ピン形式では実現できない特徴である。(3) The operation of the cylindrical wedge-shaped gas cylinder opening / piercing pin will be described. The operation of the air bag device competes for one thousandth of a second, and one of the things that affects its performance in this respect is the perforated metal fitting for opening the gas cylinder. The eccentric hollow cylindrical cylindrical wedge-shaped perforating metal fitting recited in claim 3 is a perforating metal fitting capable of meeting this demand. FIG. 3 shows that the cylindrical wedge-shaped metal fitting 9 of the present invention is in the process of punching and opening the sealed metal foil 11 of the gas cylinder 12. As shown in FIG. 3, a hollow cylinder is eccentrically drilled in the cylindrical wedge-shaped metal fitting 9, that is, a piercing pin, in the cylindrical body. Due to this eccentricity, the wedge pierces the sealed metal foil 11 to connect the inside of the gas cylinder 12 and the air bag by the gas short circuit path 10 to expedite the gas outflow time, and further the slot 13 or the gas outflow port to the cylindrical wedge-shaped metal fitting 9 main body. In addition, the area of the gas short circuit path is increased and the time required for filling the gas with the air bag is shortened. The above characteristics can only be obtained by adopting a cylindrical wedge shape in the perforated part of the gas cylinder opening metal fitting and providing a gas short-circuit outlet, which is a feature that cannot be realized with other perforation pin types.
【００１０】 （4）ガスボンベ緩衝支持装置の作用について説明する。エアバッグ装置は長 期にわたって振動の激しい自動車等車両内に取り付けられて出番のないことを祈 りながら待機している。このためエアバッグ製作に関しては細かい心の配りが必 要である。ガスボンベもこの対象の一つで、ボンベはガスボンベ開封金具集合取 付ブロック３３に片持ちに取り付けられるが、この状態では振動によるねじ込み の緩みが心配される。本考案のエアバッグ装置においてはボンベ端末部を弾性支 持してボンベを両持ちとし、ボンベの振動防止および緩み止めをはかっていると ころを特徴とする。(4) The operation of the gas cylinder buffer support device will be described. The airbag system has been installed in vehicles such as automobiles that have been subject to severe vibration for a long period of time, and is standing by in the hope that there will be no turn. Therefore, it is necessary to pay close attention to the production of airbags. The gas cylinder is also one of the objects, and the cylinder is cantilevered to the gas cylinder opening metal fitting assembly mounting block 33, but in this state, there is a concern that the screwing loosens due to vibration. The airbag device of the present invention is characterized in that the cylinder end portion is elastically supported so that the cylinder has both ends, and the cylinder is provided with vibration prevention and loosening prevention.
【００１１】 （5）衝撃感知器の集成組立構造の作用について説明する。衝撃感知器は衝撃 を感知する重錘部と、重錘の発揮する慣性力を受けて開封されるガスボンベまで の慣性力伝達作動部の二つの部分よりなる。重錘部は重錘および前後支持金具お よび取付基板からなり、慣性力伝達作動部は解錠レバ−，ハンマ−駆動ばね，ガ スボンベ開封用衝撃ハンマ−およびボンベ開封穿孔ピン，ガスボンベ等とこれら の取付基板より構成される。 衝撃慣性力の伝達過程からは、これら二つの部分は直列的に機能するものであ るが、両者の機能は独立して取り扱うことができ、それぞれの機能を完全に発揮 させるためには、そのために要求される精度・剛性を満足するものでなければな らない。この目的のためには二つの部分を分離して個々に集成組立を行い、のち 二つを結合して総合組立し、衝撃感知器を完成することが最適の製作法であり、 一方この分離して個々に集成組立する方法は製作効率を高める手段ともなる。本 考案の衝撃感知器は製作精度および製作法に関してこのような特徴を備えたもの である。(5) The operation of the assembled assembly structure of the shock sensor will be described. The shock sensor consists of two parts: a weight part that senses a shock, and an inertial force transmission operating part up to the gas cylinder that is opened by receiving the inertial force exerted by the weight. The weight part consists of a weight, front and rear support metal fittings, and a mounting board. The inertial force transmission operation part includes an unlock lever, a hammer drive spring, a gas hammer opening impact hammer, a cylinder opening perforation pin, a gas cylinder, and the like. It consists of a mounting board. From the process of transmitting the impact inertial force, these two parts function in series, but the functions of both can be handled independently, and in order to make full use of their respective functions, Must meet the accuracy and rigidity requirements of the. For this purpose, the best method is to separate the two parts into separate pieces and then assemble them individually, and then combine the two pieces into a complete assembly to complete the shock sensor. The method of individually assembling and assembling is also a means of increasing the manufacturing efficiency. The shock sensor of the present invention has such characteristics as to the manufacturing accuracy and manufacturing method.
【００１２】 （6）充填ガス配分パイプによるガス配送装置の作用について説明する。エア バッグへのガス充填時間の短縮は、エアバッグ装置における大きな課題である。 従来エアバッグへのガスの注入は一個のガス注入口によるのみであった。これで はガスが充満してエアバッグが機能するにいたるまでには多くの時間がかかる。 本考案における請求項６はこの問題を解決するものである。 図４ にこの考案の 実施例を示す。すなわちエアバッグ格納箱１４内に取り付けられたエアバッグ１ ５にジェットガスを送り込む輸送用最終パイプ１６の端末でエアバッグ１５内に 、ガス導入配分パイプ１７を設ける。このガス導入配分パイプ１７によりガスは エアバッグ１５の内部深くまで進入することができる。導入配分パイプ１７内の ガス圧は、エアバッグ入口から導入パイプ先端までの間、輸送パイプ端末におけ るガス圧からエアバッグ膨張前の内圧まで、配分パイプに設けられた噴出口のた め圧力が降下するが、ガスは導入配分パイプ１７に案内されてパイプ内を超高速 でパイプ末端まで進入するため、パイプに設けられるガス噴出口をエアバッグ内 の状況に応じて設けることにより、エアバッグへのガス充填ひいてはバッグ膨張 に要する時間を短縮する。 請求項６はエアバッグ内にガス導入・配分のパイプを設けることおよびガス噴 出口の設置に関する考案で、エアバッグ開発の上で重要なものである。(6) The operation of the gas delivery device using the filling gas distribution pipe will be described. Reducing the gas filling time for airbags is a major issue in airbag devices. Conventionally, gas is injected into the airbag only through one gas injection port. It will take a lot of time before the air bag becomes full with gas. Claim 6 in the present invention solves this problem. FIG. 4 shows an embodiment of this invention. That is, a gas introduction distribution pipe 17 is provided in the airbag 15 at the end of the final transportation pipe 16 for sending jet gas to the airbag 15 mounted in the airbag storage box 14. This gas introduction / distribution pipe 17 allows the gas to enter deep inside the airbag 15. The gas pressure in the introduction distribution pipe 17 ranges from the gas pressure at the end of the transportation pipe to the internal pressure before the airbag is inflated, from the air bag inlet to the tip of the introduction pipe, because of the pressure of the ejection port provided in the distribution pipe. However, since the gas is guided by the introduction distribution pipe 17 and enters the pipe at an extremely high speed to the end of the pipe, the gas ejection port provided in the pipe is provided according to the situation in the airbag, The time required to fill the gas into the bag and thus to inflate the bag is shortened. A sixth aspect of the present invention is a device for providing a gas introduction / distribution pipe in the airbag and a gas ejection port, which is important in developing the airbag.
【００１３】 （7）端部大気開放構造を持った充填ガス配分パイプの作用について説明する 。エアバッグ内に超高速で導かれ、エアバッグを膨張させたガスは、人体の衝突 を緩和する緩衝材として作用するが、その膨張充填時間を短くするためかなりの 高圧で蓄えられており、膨張完了時にも、なお、高めの圧力となっている。この 状態を保ったまま人体がエアバッグに衝突すると、人体は強い反発力を受け、逆 方向への衝撃力を受けかねない。 したがって、エアバッグ内ガス導入パイプ１７のガス流入下流側端部をエアバ ッグ格納箱１４内にて大気中に開放し開放端３４を設ける。これにより人体衝突 時の過度の衝撃に対しては、エアバッグ内ガスを逃がす作用を有する。このこと により、人体に対し、二重の安全性を確保するエアバッグとして、その効果が大 きく発揮される。請求項７は人命尊重の意味から安全機能最優先の考案である。(7) The operation of the filling gas distribution pipe having an open end atmosphere structure will be described. The gas that is introduced into the air bag at an extremely high speed and inflates the air bag acts as a cushioning material to mitigate the collision of the human body, but it is stored at a considerably high pressure to shorten the inflation and filling time. Even at the time of completion, the pressure is still high. When the human body collides with the airbag while maintaining this state, the human body receives a strong repulsive force and may receive an impact force in the opposite direction. Therefore, the gas inflow downstream end portion of the gas introduction pipe 17 in the airbag is opened to the atmosphere in the air bag storage box 14 and the open end 34 is provided. This has the effect of letting out the gas in the airbag against an excessive impact at the time of a human body collision. As a result, its effect is greatly exerted as an airbag that ensures double safety for the human body. Claim 7 is a device that gives the highest priority to the safety function from the viewpoint of respecting human life.
【００１４】 （8）エアバッグのセル構造の作用について説明する。エアバッグには高圧の ガスが高速で充填されるため、これに耐える強さが要求されている。またエアバ ッグ作動時において衝突被害者を防護するため、十分な強度であり、かつエアバ ッグの膨張状態において必要な厚さを保持させことが要件として挙げられる。請 求項８はこの要請に応える考案である。本考案に関わるエアバッグの構造例を図 ５に示す。 図５は、エアバッグ格納箱１４に取り付けられている膨張したエアバッグ１５ 内の構造を示すために、バッグの端末部を切り取り省略して示した図である。図 に示すように、エアバッグ１５内をバッグ外皮１８と同材質の隔壁材１９を外皮 １８に接着し、隔壁を設け、お互いに通じあった数個の部屋とする。このような バッグ構造とすることにより、隔壁設計寸法に応じて所望のエアバッグ厚さを得 ることができ、エアバッグの十分な厚さが衝撃緩衝能を高め、衝突被害の軽減効 果を大きくする。同時に、衝突被害者の体がエアバッグに衝突して生じるバッグ の急激で大きな内圧上昇にたいする補強の役割を果たす。請求項８はエアバッグ 装置に課せられた使命を達成する上から忘れられてはならない考案である。(8) The operation of the cell structure of the airbag will be described. Since high-pressure gas is filled into an airbag at high speed, it is required to have sufficient strength to withstand this. In addition, in order to protect the collision victims when the air bag is activated, it is necessary to have sufficient strength and to maintain the necessary thickness in the expanded state of the air bag. Claim 8 is a device to meet this request. Fig. 5 shows an example of the structure of the airbag according to the present invention. FIG. 5 is a view in which the end portion of the bag is cut away to show the structure of the inflated airbag 15 attached to the airbag storage box 14. As shown in the figure, inside the airbag 15, a partition wall material 19 made of the same material as that of the bag outer skin 18 is adhered to the outer skin 18 to form a partition wall so that several chambers communicate with each other. With such a bag structure, a desired airbag thickness can be obtained according to the design size of the partition wall, and the sufficient thickness of the airbag enhances the shock absorbing ability and reduces the impact damage. Enlarge. At the same time, it acts as a reinforcement for the rapid and large increase in internal pressure of the bag caused by the collision victim's body colliding with the airbag. Claim 8 is a device that cannot be forgotten in order to achieve the mission of the airbag device.
【００１５】 （9）エアバッグ格納箱の自在取付構造の作用について説明する。エアバッグ 降下式後付形エアバッグ装置においては、バッグの降下の方向および姿勢を最適 なものとするため、エアバッグ格納箱部の取付状態を細かく調整し得ることが要 求されている。この要求に応えるものが、 図６ に示す機構の請求項９の考案で ある。 本ボ−ル式自在継手取付機構は、車両天井等の車両乗車員上部に固定される取 付金具２０，前後位置調整用のボ−ルと一体になっている腕２１およびエアバッ グ格納箱１４に一体となっている部分と、この部分と対をなす二つ割りになって いるボ−ル穴付きエアバッグ箱側取付部材２２、の三つの部材よりなる。車両天 井等に取り付けられている金具に取り付けられた取付金具２０に、エアバッグ格 納箱１４の前後方向位置を調整した後、ボ−ルと一体の腕２１を固定する。次に エアバッグの降下後の姿勢を考慮の上、エアバッグ箱側ボ−ル穴付き取付部材２ ２を締め付けて、エアバッグ格納箱１４の取付が完了する。図６ではこれら部材 間の関係姿勢を図示し、締め付けねじを省略してあるが、その位置は示されてい る。本エアバッグ装置はエアバッグの降下後の姿勢まで調整し得る特徴を持った 考案を含むものである。(9) The operation of the structure for freely mounting the air bag storage box will be described. In the air bag lowering type retrofit type air bag system, it is required that the mounting state of the air bag storage box part can be finely adjusted in order to optimize the direction and posture of the air bag lowering. What meets this demand is the invention of claim 9 of the mechanism shown in FIG. This ball type universal joint mounting mechanism includes a mounting bracket 20 fixed to an upper portion of a vehicle occupant such as a vehicle ceiling, an arm 21 integrated with a ball for adjusting the front-rear position, and an air bag storage box 14. And an airbag box side attachment member 22 with a ball hole which is paired with this portion. After adjusting the position of the airbag storage box 14 in the front-rear direction to a mounting bracket 20 mounted on a bracket mounted on a vehicle roof or the like, an arm 21 integral with a ball is fixed. Next, considering the posture of the airbag after the descent, the mounting member 22 with the ball hole on the airbag box side is tightened to complete the mounting of the airbag storage box 14. FIG. 6 shows the relational attitude between these members, and the tightening screws are omitted, but their positions are shown. This airbag device includes a device having a feature that the posture of the airbag after being lowered can be adjusted.
【００１６】 （10）エアバッグ格納箱の安定固定装置の作用について説明する。エアバッグ 降下式後付形エアバッグ装置では、そのエアバッグ格納箱は天井等上部に取り付 けられているため、車両の走行振動の影響を受け易い。この対策として設けられ ているのが図７に示される請求項１０の考案である。 本姿勢安定用緩衝足２３は、エアバッグ格納箱１４本体の前面側に設けられて いるねじ穴２４にねじ込まれ、エアバッグ格納箱のすぐ前にある車両のフロント ガラス等に、緩衝足先端にはめ込まれている緩衝材２５を、ねじの作用で圧着さ せて、エアバッグ格納箱１４の姿勢を安定させる役割を持たせたものである。こ の緩衝足の圧着効果により、格納箱に加わる車両から来る振動およびガス噴射作 動時の衝撃緩衝の影響を減衰させる効果を得る。請求項１０はエアバッグ格納箱 の姿勢安定化および振動，衝撃緩衝の効果をもたらす特徴を持った緩衝足に関す る考案である。(10) The operation of the stable fixing device for the airbag storage box will be described. Airbags In the drop-down retrofit type airbag device, the airbag storage box is attached to the upper part of the ceiling, etc., so it is easily affected by vehicle running vibration. It is the invention of claim 10 shown in FIG. 7 that is provided as a countermeasure against this. This posture-stabilizing cushioning foot 23 is screwed into a screw hole 24 provided on the front side of the main body of the airbag storage box 14, and is attached to the tip of the cushioning foot on the windshield of the vehicle immediately in front of the airbag storage box. The cushioning material 25 that has been fitted is crimped by the action of a screw to have a role of stabilizing the posture of the airbag storage box 14. Due to the crimping effect of the cushioning feet, the effect of damping the vibrations coming from the vehicle added to the storage box and the impact cushioning at the time of gas injection operation is obtained.
