Abstract
Description
図1に示されるように、乗員保護装置10は、車両用シート12に搭載されている。車両用シート12は、図示しない自動車の車体における車両幅方向中央に対し左右何れか(本実施形態では左側)にオフセットして配置されている。この車両用シート12は、シートクッション14と、シートクッション14の後端に下端が連結されたシートバック16と、シートバック16の上端に設けられたヘッドレスト18とを含んで構成されている。また、本実施形態の車両用シート12では、ヘッドレスト18とシートバック16とが一体に形成された構造とされている。
図1に示されるように、多方位エアバッグ装置20は、エアバッグとしての多方位エアバッグ30と、ディフューザ管40と、インフレータ32とを含んで構成されている。また、多方位エアバッグ30は、図3に示されるように、折り畳まれた状態で車両用シート12の上部に収納されており、インフレータ32から発生するガスの供給を受けて膨張展開される。以下、具体的に説明する。
次に、エアバッグ移動機構22について説明する。図6に示されるように、エアバッグ移動機構22は、ガイド筒体50と、ベースプレート58と、圧縮コイルバネ52と、ワイヤ54と、巻取モータ56とを含んで構成されている。
多方位エアバッグ装置20のインフレータ32及びエアバッグ移動機構22は、ECU42と電気的に接続されている。また、ECU42は、プリクラッシュセンサなどの衝突予知センサ44及び衝突センサ46と電気的に接続されている。さらに、ECU42は、シートベルト装置24を構成する図示しないリトラクタとも電気的に接続されている。
次に、実施形態の作用について説明する。
なお、本実施形態のエアバッグ移動機構22では、図6及び図7に示されるように、ベースプレート58を圧縮コイルバネ52の付勢力で押し上げることによって多方位エアバッグ30及びディフューザ管40を移動させたが、これに限定されない。例えば、図8に示す変形例の構成を採用してもよい。
