にはガス発生器を起動させ、これにより格納状態にある
エアバッグを展開膨張せしめ、乗員の受ける衝撃を緩和
し、車輌の安全性を向上せしめるものである。As is already known, a vehicle's airbag system detects the impact of a car collision, and if the impact is greater than a set value, it activates a gas generator, thereby deploying and inflating the stored airbag. This reduces the impact on the occupants and improves the safety of the vehicle.

以上の如く可動部材３０を構成したこのは次の理由によ
る。The reason for configuring the movable member 30 as described above is as follows.
既述の如く電源、特に電圧条件が定まればソレノイド装
置の可能な最大吸引力は決められてしまい、一方、可動
部材を高速で作動させる場合には殆んどの力は可動部材
を加速するために使用され、これがため磁力を低下させ
ることなく可動部材の重量を軽減する必要がある。As mentioned above, once the power source, especially the voltage conditions, are determined, the maximum possible suction force of the solenoid device is determined.On the other hand, when operating a movable member at high speed, most of the force is due to accelerating the movable member. Therefore, it is necessary to reduce the weight of the movable member without reducing the magnetic force.
このためには可動部材内の導磁部の断面積を均一にする
ことが磁束有効利用の点からも好ましい。For this purpose, it is preferable to make the cross-sectional area of the magnetically conductive portion within the movable member uniform from the viewpoint of effective use of magnetic flux.
従って第７図の有半の矢印の如く磁力が流れる場合には
、可動部材３０の本体上の有効磁束の半径ｒの円内にａ
方向から磁力線が入るとするとその断面積はπｒ２とな
る。Therefore, when the magnetic force flows as shown by the arrow with half of the arrow in FIG.
If a line of magnetic force enters from that direction, its cross-sectional area will be πr2.
一方、磁力線は半径ｒの円筒部周壁からｂ方向へ流出す
ることとなるが、その断面は２πｒｈである。On the other hand, the lines of magnetic force flow out from the peripheral wall of the cylindrical portion with radius r in the direction b, and the cross section thereof is 2πrh.
ｈは本体の高さ、即ち肉厚である。h is the height of the main body, that is, the wall thickness.
従って上の条件からこれらが等しいことが望ましいから πｒ２−２πｒｈ ｒ ＝２ ｈとなる。Therefore, from the above conditions, it is desirable that these are equal. πr2−2πrh r = 2 h.
従ってθ＝２ ｊａｎ ”２−： １２７’となる。Therefore, θ=2 jan "2-: 127'.
即ち、第８図に示される如く磁束の有効利用を図りつつ
磁力線の関与しない部分を軽量除肉した場合には円錐凹
状となり、この角度θは上記により１２７’となる。That is, as shown in FIG. 8, when the portions that are not involved in the lines of magnetic force are lightly thinned out while attempting to utilize the magnetic flux effectively, a concave concave shape is formed, and the angle θ is 127' as described above.
しかしながらこれではオーバースクエアであってこじれ
る虞れか゛あり、ガイド用のロッドが必要で、これも軽
量化のためできるだけ細くする必要がある。However, this is oversquare and may become difficult, and a guide rod is required, which also needs to be as thin as possible to reduce weight.
従って第９図で示される如き構造となる。Therefore, the structure is as shown in FIG.
もつとも実際上は可動部材３０の端面にはこれのストロ
ーク分のギャップがあり、周面には摺動に必要なギャッ
プがあるため最適値は必ずしも上式には完全に一致しな
い場合もある。However, in reality, the end face of the movable member 30 has a gap corresponding to its stroke, and the circumferential face has a gap necessary for sliding, so the optimum value may not always completely match the above equation.
以上において、コイル２３への電気式センサＢの衝突検
出動による通電で付勢され、可動部材３０はコア２５の
端面２５ Ｃに吸引、吸着され、この状態を第６図で示
した。In the above, the movable member 30 is energized by the energization caused by the collision detection movement of the electric sensor B to the coil 23, and the movable member 30 is attracted to the end surface 25C of the core 25, and this state is shown in FIG.
この作動は上記の如く磁束を有効に利用しつつ軽量化を
図ったため、極めて高速でコア２５に吸着され、これに
より２ｍｓで２ｍｍ程度のストロークが得られた。Since this operation was carried out to reduce weight while effectively utilizing magnetic flux as described above, it was attracted to the core 25 at an extremely high speed, and a stroke of approximately 2 mm was obtained in 2 ms.

如く構成されている。A mechanical sensor J is also associated with the activation mechanism 53, and is configured such that the airbag can be activated by detection by either sensor B or J.
以上の説明で明らかなように本考案によれば次の効果を
発揮する。As is clear from the above explanation, the present invention provides the following effects.
エアバッグ収納状態維持用リンク機構を保持する可動部
材の吸引動作を行うにあたり、可動部材における磁束が
入ってくる部分と出ていく部分の各面積を等しくシ、且
つ磁路となる部分以外の部分を欠肉することによって、
軽量化を図り吸引力を有効に発生させ、これによってエ
アバッグ装置の起動を円滑且つ高速に行うことができ、
エアバッグ装置の作動の確実・迅速化を達成し、作動信
頼性を高めることができる。When performing the suction operation of the movable member that holds the link mechanism for maintaining the airbag storage state, the area of the part of the movable member where the magnetic flux enters and the part where the magnetic flux exits is made equal, and the area other than the part that becomes the magnetic path is made. By cutting out the
By reducing the weight and effectively generating suction force, the airbag device can be activated smoothly and quickly.
It is possible to achieve reliable and speedy operation of the airbag device, and increase operational reliability.
また、可動部材を吸引するソレノイドに電流を供給する
電源が車載バツテノであるためにソレノイドの吸引能力
には一定の制限があるわけであるが、本考案によれば、
ソレノイド装置、電源について特別な仕様変更を施す必
要もなく、許容条件の範囲内で最良の作動特性を得るこ
とができると共に、製作するにあたってもこれを安価に
実現することができる。In addition, since the power supply that supplies current to the solenoid that attracts the movable member is an on-vehicle battery, there is a certain limit to the suction ability of the solenoid, but according to the present invention,
There is no need to make any special specification changes to the solenoid device or power supply, and the best operating characteristics can be obtained within the range of allowable conditions, and this can be achieved at low cost.
