Description
【０００１】0001
本考案はエアバッグ作動後にシートベルトを自動的に解放するシートベルト解 放装置に関する。 This invention is a seatbelt solution that automatically releases the seatbelt after airbag activation. related to a radiation device.
【０００２】0002
車両の衝突時に搭乗者を衝突から守るため、シートベルトが使用されるが、最 近ではエアバッグも使用される傾向にある。周知のようにエアバッグは衝突時に 瞬時に膨脹して搭乗者の前面に広がるものであるから、搭乗者が車室内壁に頭を ぶつけたりすることを未然に防止できる。 Seat belts are used to protect passengers from collisions during vehicle collisions, but they are Recently, airbags have also been used more frequently. As is well known, airbags are used in the event of a collision. Because it instantly inflates and spreads out in front of the passenger, the passenger may not be able to keep his or her head against the interior wall. You can prevent bumps from happening.
【０００３】0003
エアバッグが作動するような衝突事故が生じた場合、二次災害として車両火災 や後続車の追突事故が生じ易い。このため事故車両の搭乗者は速やかに脱出した り、救出する必要がある。 In the event of a collision in which an airbag deploys, a vehicle fire may occur as a secondary disaster. or a rear-end collision with a vehicle behind you. As a result, the occupants of the accident vehicle quickly escaped. and need to be rescued.
【０００４】 しかしながら、事故車両の搭乗者がシートベルトをしていると、エアバッグが 膨脹し、しかも事故の衝突で車両が変形していることもある状態ではロック解放 作業に手間取り、搭乗者の脱出や救出が遅れる問題がある。0004 However, if the occupants of the accident vehicle were wearing seatbelts, the airbag would If the vehicle expands and the vehicle is deformed due to an accident, the lock will be released. There is a problem in that the work is time-consuming and the evacuation and rescue of passengers is delayed.
【０００５】 本考案は、エアバッグ作動後の安全な状態において自動的にシートベルトを解 放することで、搭乗者の脱出や救出を容易にすることを目的としている。[0005] This invention automatically releases the seatbelt in a safe condition after the airbag is activated. The purpose of this release is to facilitate the escape and rescue of passengers.
【０００６】[0006]
本考案は、シートベルトのロック機構または取付部を自動的に解放するシート ベルト解放手段と、エアバッグの作動を検出する手段と、車両の停止を検出する 手段と、エアバッグが作動し、且つ車両が停止してから一定時間後に前記シート ベルト解放手段を作動させる手段とを備えてなることを特徴とするものである。 This invention is a seat that automatically releases the seatbelt locking mechanism or attachment part. Belt release means, means for detecting airbag activation, and detecting vehicle stoppage. the seat after a certain period of time after the airbag is activated and the vehicle has stopped; and means for activating the belt release means.
【０００７】[0007]
エアバッグが作動し、且つ車両が停止したら搭乗員は速やかに事故車両から脱 出した方が良い。そこで、衝撃が収まる時間（１秒程度）を待ってからシートベ ルトを自動的に解放する。この解放手段は既存のロック機構を解放するものでも 、別途設けた機構によりシートベルト取付部を解放するものでもよい。 Once the airbag deploys and the vehicle stops, the occupants should immediately exit the accident vehicle. It's better to take it out. Therefore, wait until the impact has subsided (about 1 second) before using the seatbelt. automatically releases the root. This release means may also release the existing locking mechanism. Alternatively, the seat belt attachment portion may be released by a separately provided mechanism.
【０００８】 このシートベルト解放手段はエアバッグが作動していなかったり、車両が走行 している場合には作動しないため、衝突時の衝撃で搭乗者が車外に投げ出される 心配はない。[0008] This seatbelt release means may be used if the airbag is not activated or the vehicle is running. If the system is running, the driver will not be able to operate, and the impact of a collision will cause the occupants to be thrown out of the vehicle. No worries.

図１は本考案の一実施例を示す構成図で、Ａはエアバッグ装置、Ｂはシートベ ルト解放装置である。 Figure 1 is a configuration diagram showing one embodiment of the present invention, where A is an airbag device and B is a seatbelt. It is a root release device.
【００１０】 本例のエアバッグ装置Ａは３つのＧセンサ１〜３を有し、このうちセーフィン グセンサ１で小さな衝撃を検出し、フロントエアバッグセンサ２とセンターエア バッグ３でそれぞれ大きな衝撃を検出する。0010 The airbag device A of this example has three G sensors 1 to 3, of which SafeFin The airbag sensor 1 detects a small impact, and the front airbag sensor 2 and center air A large impact is detected in each bag 3.
【００１１】 センサ１が作動するとエアバッグ点火装置４の電源側がオンになり、またセン サ２が作動すると点火装置４のアース側がオンになる。従って、センサ１，２が 共に作動すると点火装置４に電流が流れ、図示せぬエアバッグ内の燃焼剤が燃焼 して該エアバッグはその燃焼ガスで瞬時に膨脹する。[0011] When sensor 1 is activated, the power supply side of airbag igniter 4 is turned on, and the sensor When the sensor 2 is activated, the ground side of the ignition device 4 is turned on. Therefore, sensors 1 and 2 When both operate, a current flows to the ignition device 4, and the combustion agent inside the airbag (not shown) is combusted. The airbag is then instantly inflated by the combustion gas.
【００１２】 センサ３が作動すると点火判定回路５を通して点火装置４のアース側がオンに なる。従って、センサ１，３が共に作動しても点火装置４には電流が流れる。0012 When the sensor 3 is activated, the ground side of the ignition device 4 is turned on through the ignition determination circuit 5. Become. Therefore, even if both sensors 1 and 3 are activated, current flows through the ignition device 4.
【００１３】 本例のシートベルト解放装置Ｂはシートベルト解放回路６と、シートベルト解 放ソレノイド７からなる。シートベルト解放回路６は点火装置４に流れる電流の 有／無、従ってエアバッグの作動／未作動を示すエアバッグ作動信号と、車両の 走行／停止を示す車速信号を入力としてソレノイド７への通電を制御する。[0013] The seatbelt release device B of this example includes a seatbelt release circuit 6 and a seatbelt release circuit 6. It consists of a discharge solenoid 7. The seat belt release circuit 6 controls the current flowing to the ignition device 4. The presence/absence of the airbag, and therefore the airbag activation signal indicating whether the airbag is activated or not, and the vehicle's airbag activation signal. The energization of the solenoid 7 is controlled by inputting a vehicle speed signal indicating running/stopping.
【００１４】 図２はこのシートベルト解放回路６の詳細図で、６１はエアバッグ作動信号か らエアバッグの作動／未作動を検出するエアバッグ作動検出回路、６２は車速信 号から車両の停止を検出する車両停止検出回路、６３は両検出回路の出力を２入 力とするアンド回路、６４はアンド回路６３の出力を１秒間遅延させるディレイ 回路、６５はその出力を増幅してソレノイド７に通電するアンプである。[0014] Figure 2 is a detailed diagram of this seatbelt release circuit 6, and 61 is the airbag activation signal. 62 is an airbag activation detection circuit that detects whether the airbag is activated or not; 63 is a vehicle stop detection circuit that detects the stop of the vehicle from No. 64 is a delay that delays the output of AND circuit 63 for 1 second. The circuit 65 is an amplifier that amplifies the output and energizes the solenoid 7.
【００１５】 この構成によるシートベルト解放回路６はエアバッグが作動し、且つ車両が停 止してから１秒経過するとソレノイド７に通電してシートベルトを解放する。こ の１秒は車両停止後の衝撃が収まるのを待つ時間であり、この遅延動作でシート ベルト解放の安全性を更に高める。[0015] The seatbelt release circuit 6 with this configuration is configured when the airbag is activated and the vehicle is stopped. When one second elapses after the seat belt is stopped, the solenoid 7 is energized to release the seat belt. child The 1 second is the time to wait for the impact to subside after the vehicle has stopped, and this delayed operation allows the seat to Further increases the safety of belt release.
【００１６】 図３はシートベルト解放部の機構図である。シートベルト８は二片８１，８２ に分かれ、両片はバックル式のロック機構９で着脱自在にロックされる。このシ ートベルト８のロック機構９とは逆の端部はいずれも車体側に取付けられている が、本例ではその一片８１の取付部１０をソレノイド７で解放できるようにして ある。[0016] FIG. 3 is a mechanical diagram of the seat belt release section. Seat belt 8 has two pieces 81 and 82 Both pieces are removably locked by a buckle-type locking mechanism 9. This Both ends of the seat belt 8 opposite the locking mechanism 9 are attached to the vehicle body side. However, in this example, the mounting portion 10 of the piece 81 can be released by the solenoid 7. be.
【００１７】 即ち、ソレノイド７が作動すると引抜かれるピン７１を取付部１０の結合部分 に予め挿入しておき、常時はシートベルト８の使用に支障がないようにしておく 。そして、ソレノイド７に通電してピン７１を引抜くとロック機構９が結合した 状態でもシートベルト８が解放され、搭乗者が容易に離脱できるようにする。[0017] That is, the pin 71 that is pulled out when the solenoid 7 is activated is connected to the connecting part of the mounting part 10. Insert the seat belt 8 in advance so that it does not interfere with the use of the seat belt 8 at all times. . Then, when the solenoid 7 is energized and the pin 71 is pulled out, the locking mechanism 9 is engaged. Even in this state, the seat belt 8 is released and the passenger can easily leave the seat.
【００１８】 このシートベルトの自動解放はロック機構９において行ってもよい。即ち、通 常のロック機構９はロック解除用の押釦９１を有するが、これをソレノイド７（ または他の駆動手段）によっても解除できる構成にする。[0018] This automatic release of the seat belt may be performed by the lock mechanism 9. In other words, The usual locking mechanism 9 has a push button 91 for unlocking, but this is connected to the solenoid 7 ( or other driving means).
【００１９】[0019]
以上述べたように本考案によれば、エアバッグ装置を搭載した車両が衝突事故 を起こした場合、シートベルトを着用したままエアバッグ装置が作動しても、自 動的にシートベルトが解放されるため、搭乗者の脱出や救出が容易になる利点が ある。 As described above, according to the present invention, a vehicle equipped with an airbag device can be used in a collision accident. If an accident occurs, even if the airbag system deploys while the seatbelt is worn, it will not automatically activate. Seat belts are dynamically released, which has the advantage of making it easier for passengers to escape and rescue passengers. be.
