Abstract

PROBLEM TO BE SOLVED: To lighten load applied to the breast and the head of an occupant when an impact occurs by operating a power generating device so that when the occurrence of an impact is detected by an impact occurrence detecting means, the waist and its vicinity of the occupant become the maximum load before the maximum load is applied to the head and the breast of the occupant. SOLUTION: When the occurrence of an impact is detected by an impact occurrence detecting means 13, a gas generator 11 is ignited to generate gas, and the free end side of a piston member 10 is instantaneously projected from a cylinder 9 by suddenly increasing the internal pressure of the cylinder 9. Whereupon, a link member 3 connected to the free end part of the piston member 10 is rotated clockwise, and at the free end of a short arm part 3b, a bar 6 is moved upward together with a long arm part 3a of a power generating device 8 to expand a seat, thereby supporting the femoral region, the hip and the waist of the occupant from the front. The timing of igniting the gas generator 11 is the timing of swelling the seat so that before the maximum load is applied, the waist of the occupant reaches the maximum acceleration.

【0018】次に、本実施形態の作動要領について説明する。 Next, it will be described operation procedure of this embodiment. まず、走行中、衝撃発生検出手段13により、衝突などの衝撃発生が検出されたら、ガス発生装置11に点火してガスを発生させ、シリンダ9の内圧を急激に高めることでピストン部材10の遊端側をシリンダ9から瞬時に突出させる。 First, during running, the impact occurrence detection unit 13, upon detecting the occurrence of impact of the collision, to ignite the gas generator 11 to generate a gas, the piston member 10 by rapidly increasing the inner pressure of the cylinder 9 Yu protruding the end side from the cylinder 9 instantaneously. すると、ピストン部材10の遊端部10aに接続されたリンク部材3が時計回りに回転し、 Then, the link member 3 connected to the free end 10a of the piston member 10 rotates clockwise,
図2に想像線で示すように、短アーム部3b遊端には後記する動力発生装置8の長アーム部3aと共にバー6が上方に移動し、シートを膨出(突出)させ、乗員の大腿部、臀部、腰部を前方よりサポートする。 As shown in phantom in FIG. 2, the long arm portion 3a of the power generating device 8, which will be described later in the short arm portion 3b free end moves bar 6 upwards, the swelled (projected) sheet, an occupant of a large thighs, buttocks, support from the front of the waist.

【0019】ここで、ガス発生装置11に点火するタイミングは、乗員の頭部及び胸部が最大加速度に達する、 [0019] Here, the timing to ignite the gas generator 11, the occupant's head and chest reaches maximum acceleration,
即ち最大荷重が加わる前に乗員の腰部が最大加速度となるようにシートを膨出(突出)させるようなタイミングとなっている。 That occupant lumbar before the maximum load is applied is a timing as to bulge (protrude) the sheet so that the maximum acceleration.

【0020】図4(a)〜(c)に、本発明が適用された車両用シート装置に於ける衝撃発生時の乗員各部の加速度と時間との関係を実線で示す。 [0020] FIG. 4 (a) ~ (c), showing the relationship between acceleration and time of the occupant each unit of time in an impact occurs seat apparatus for a vehicle to which the present invention is applied in a solid line. 破線は従来の車両用シート装置の場合を示す。 The broken line shows the case of a conventional vehicle seat device.

【0021】一般に、35mphで正面衝突、ベルトゆるみなし、AM50%ダミー使用等の標準的な試験条件では従来のシート装置の場合、衝突後、胸部と腰部には約40〜50ms後、ほぼ同時に最大荷重が発生し、その約10ms遅れて頭部に最大荷重が発生する(破線)。 [0021] Generally, a head-on collision at 35 mph, no belt slack, in the case of the conventional seat device a standard test conditions, such as AM50% dummy use, after the collision, the chest and waist After about 40~50Ms, up substantially simultaneously load occurs, the maximum load is generated in the head with a delay of which about 10 ms (dashed line). それに対して本発明が適用されたシート装置の場合、乗員が前方移動を開始する前に衝撃検出して作動し(衝突後20ms〜30ms以内に作動が終了)、かつ乗員に常に接している部位(大腿部)に滑り出し防止部材があるため(例えば臀部前方150mm〜250mm For seat device to which the present invention is applied thereto, a portion occupant (end operation within the collision after 20Ms~30ms) impact detection to operate before starting the forward movement, and is always in contact with the occupant since there is Suberidashi prevention member (thigh) (e.g. hip forward 150mm~250mm
程度の位置)、乗員の移動によりまず腰部が拘束されて、滑り出し防止部材が変形することによりエネルギーを吸収する(衝突後約30ms〜40ms)。 The degree of position), and the waist is first constrained by the movement of the occupant, Suberidashi preventing member absorbs energy by deforming (approximately after impact 30Ms~40ms). その後、 after that,
更に乗員の移動によりベルト張力が最大となり、胸部が拘束されて最大荷重となり(衝突後約40ms〜50m Furthermore belt tension is maximized by movement of the occupant, the chest is restrained a maximum load (approximately after a collision 40ms~50m
s)、続いて頭部に最大荷重が発生する(衝突後約50 s), followed by the maximum load is generated in the head by (approximately after the collision 50
ms〜60ms)。 ms~60ms).

【0022】このように、本発明が適用された車両用シート装置では、腰部及びその近傍の荷重のピークが他の部分よりも早期に現出することにより(図3(c))、 [0022] Thus, the vehicle seat apparatus to which the present invention is applied, by the peak load of the waist and the vicinity thereof is revealing earlier than other portions (FIG. 3 (c)),
概ね領域Cに示される面積、即ちエネルギー分だけ頭部及び胸部に加わるエネルギー(領域A、B)が減少し、 Generally the area shown in the region C, ie the energy amount corresponding energy applied to the head and chest (regions A, B) is reduced,
また、腰部の最大荷重はやや大きくなるものの頭部、胸部の最大荷重が各々著しく軽減されていることがわかる。 The maximum load of the waist it can be seen that the slightly larger ones of the head, the maximum load of the chest are each significantly reduced.

【0023】尚、ガス発生装置11によるガスの発生が終わり、動力発生装置7の駆動力が消失してもワンウェイロック機構7により、上方に移動したバー6が下方に戻ることがなく、サブマリン現象の防止効果が持続する。 [0023] Incidentally, the end is the generation of gas by the gas generator 11, by the one-way lock mechanism 7 also the driving force of the power generating device 7 is lost, the bar 6 moves upward without back downward, submarine phenomenon the effect of preventing persists.

【0024】上記構成では、滑り出し防止部材が回転にて持ち上がるようにしたが、上方に直線移動するものでも良く、バーに限らず、エネルギーを吸収できるもの(例えば鉄、アルミ、樹脂等の各種素材、ベルト、ワイヤ織物等の二次加工品、オリフィス径等による流量調整によりエネルギー吸収制御されたエアバック、あるいはエネルギー吸収メカニズム機構等)を用いれば、一層乗員への負荷が低減される。 [0024] In the above configuration, although Suberidashi prevention member was set to lift by the rotation may be one linearly moved upward, not limited to the bar, which can absorb energy (e.g., iron, aluminum, various resins such as the material , belt, woven wire or the like fabricated articles, by using the energy absorbed controlled air back by the flow rate adjustment by the orifice diameter and the like, or energy absorbing mechanism mechanism or the like) is reduced load on the further passenger.

【0025】 [0025]

【発明の効果】上記した説明により明らかなように、本発明による車両用シート装置によれば、車両の衝撃発生が検出されたら、乗員の頭部及び胸部に最大荷重が加わる前に乗員の腰部及びその近傍が最大荷重となるように動力発生装置を作動させて滑り出し防止部材をもってシートクッションの一部を上方へ突出させて乗員の腰部及びその近傍を拘束することで、即ち乗員の胸部、頭部に加わる荷重を分散することで、人体の重要部位である胸部及び頭部に加わる最大荷重が下がり、その損傷を低減できると共にかつ確実にサブマリン現象を防止できる。 As evidenced by the foregoing description, according to the present invention, according to the vehicle seat apparatus according to the present invention, when the impact occurrence of the vehicle is detected, the occupant's waist before joining the maximum load to the occupant's head and chest and that the vicinity thereof to restrain the part is protruded upward waist and the vicinity thereof of the occupant of the seat cushion with Suberidashi preventing member by operating the power generator such that the maximum load, i.e. the passenger's chest, head by dispersing a load applied to parts, lower maximum load applied to the chest and head is a human critical areas, it can be prevented and reliable submarine phenomenon can be reduced and the damage.
