Abstract
Description
図1は、乗用車における右前ドアでの分解斜視図であり、図2は図1の右前ドアの概略正面図である。
図4は破損検出装置30の斜視図を示す。図5,6は検出具40をウィンドウガラス5に取り付けた状態を示す。図7は検出具40をウィンドウガラス5に取り付けた後においてウィンドウガラス5が割られて全体にひびが入ったときを示す。図8,9はウィンドウガラス5が割られて検出具40により一部領域を粉砕した状態を示す。
通常時、即ち、ウィンドウガラス5の非破損時においては、検出具40は図4,5,6に示す状態となっている。乗員が車両から離れるときにウィンドウガラス5が全閉または少し(数cmほど)開いているとする。コントローラ70は図11のセンサ出力レベルからウィンドウガラス5の位置を検出しており、パーキングブレーキが操作されている時にウィンドウガラス5が全閉または少し開いているとガラスの割れ検知モードを設定する。このとき、ウィンドウガラス5の下部に取り付けられた検出具40は、貫通孔5cを拡開する方向に付勢している。また、ウィンドウガラス5の非破損時には、一対のアーム45,46とプレート部42,43とが協働して磁石50を把持している。非破損時にはセンサユニット60の第1の磁気センサ61の前方に磁石50が位置している。
(1)検出具40は、ウィンドウガラス5に設けられた貫通孔5c内に位置し、自身の弾性力にてウィンドウガラス5の貫通孔5cを拡開する方向に付勢する。したがって、ウィンドウガラス5の破損に伴い、検出具40はウィンドウガラス5の貫通孔5cの周囲の部分を粉砕して、自身の少なくとも一部を変位させる。よって、ウィンドウガラス5が完全に粉砕せずに残るような場合でも、破損検出装置30はウィンドウガラス5の破損を確実に検出することができる。
(4)検出具40の一部の変位に伴って被検出部材としての磁石50の把持を解除するので、検出具40ではなく磁石50の動きによりウィンドウガラス5の破損を検出することができる。
実施形態は前記に限定されるものではなく、例えば、次のように具体化してもよい。
駆動部はモータを有する構成に限らず、乗員の手動によって駆動する構成でもよい。
センサユニット60は一対の磁気センサ61,62を備えていたが、1つの磁気センサを具備するものであってもよい。
開閉式ウィンドウガラスではなく固定式(嵌め込み式)のウィンドウガラスに破損検出装置30を取り付けてもよい。
