Description

【０００１】
【発明の属する技術分野】
本発明は、主に乗り物のサンルーフに利用可能な挟み込み検知用感圧センサ装置に関する。
【０００２】
【従来の技術】
例えば、自動車のサンルーフは、固定ルーフの開口部を可動パネルで開閉可能になっていて、可動パネルを閉鎖するときに固定ルーフとの間で、手、指又はその他のものを挟み込んでしまうことがあり、その挟み込みを検出して可動パネルの閉動作を停止するために挟み込み検知用感圧センサ装置が設けられている。
【０００３】
この種の挟み込み検知用感圧センサ装置としては、特開平１０−３３１５１８号公報に開示されたものがあり、この技術は、「動力閉鎖要素、特に封止要素を具備しかつポリウレタンフォームクラッドを有する閉鎖要素に好適に使用されるウエッジ（ｗｅｄｇｉｎｇ）検出装置であって、実際の封止機能とは別に、前記封止要素はスイッチ要素を被覆、保護かつ作動する機能を備えた要素を含み、前記スイッチ要素は前記閉鎖要素のポリウレタンフォームクラッド内に形成され、かつ前記封止要素はそれぞれのスイッチ要素上に適合するように配置された２つの動力伝達領域を有する構成」である。
【０００４】
この第１従来技術では、挟み込時の封止要素の変形によって、基部領域がスイッチ要素を作動させるようになっているが、基部領域及びスイッチ要素は封止要素内に注入成形しなくてはならない。すなわち、ウエザーストリップの内部に感圧センサを構成する複数の構成部材を挿入配置しなくてはならない。
このような成形は非常に困難であり、挟み込みを感知することのできる外力反応方向域（弾性変形領域）が狭く、感知精度が低い、等の種々の問題点を含んでいる。
【０００５】
この問題点の一部を克服するものとして、パワーウインド用ではあるが、特開平９−２０９６５１号公報に開示されたものがある。
この第２従来技術は、「窓枠によって形成される窓開口内で進退する窓体と、窓枠の室内側周縁に配設され、外力を感知する感知手段と、前記感知手段によって感知される外力が、所定値を越えた時に前記窓体の進退を停止する進退停止手段とを備える動力付窓開閉装置において、前記感知手段は、弾性変形可能なチューブと、前記チューブ内に絶縁部を介在して前記チューブの長手方向に延びる２つ導電部とを有し、前記感知手段は、外力によって前記チューブが変形して前記２つの導電部が接触することにより外力を感知し、前記２つの導電部が接触し得る外力方向範囲の中心方向である感知中心が、前記窓体が進退する進退面に対して所定角度を有して傾いている部位が設けられている」ものである。
【０００６】
【発明が解決しようとする課題】
前記第２従来技術では、チューブ及び２つの導電部を押し出し成形で一体成形して感圧チューブセンサを形成し、この感圧チューブセンサをウエザーストリップに形成した孔に挿入して配置しているので、外力反応方向域が広く感知精度を高めることができるが、感圧チューブセンサの挿入、特にコーナ部での挿入が困難であり、サンルーフのウエザーストリップは風雨に晒されかつ開閉に関わらず常に応力が働いており、そのようなサンルーフに使用するとセンサへのダメージも多く、破損した場合の取り替えが困難であり、可動パネル全体の交換になるなど、メンテナンス性及びコスト性が悪くなっている。
【０００７】
本発明は、このような従来技術の種々の問題点を解決できるようにした挟み込み検知用感圧センサ装置を提供することを目的とする。
本発明は、チューブ形状の感圧センサをセンサ装着具でウエザーストリップに沿わせて配置することにより、挟み込み検知の信頼性を向上し、感圧センサの耐久性の向上及び着脱の容易化が実現できるようにした挟み込み検知用感圧センサ装置を提供することを目的とする。
【０００８】
【課題を解決するための手段】
本発明における課題解決のための具体的手段は、次の通りである。
第１に、乗り物の固定ルーフに形成した開口部を開閉するサンルーフは、前記固定ルーフに対して可動する可動パネルと、この可動パネルの外周部の室内側の面に設けた第１取付け部材と、この第１取付け部材よりさらに外側の可動パネルの外周縁に設けられた第２取付け部材と、この第２取付け部材の全周囲に沿って設けられたウエザーストリップとを有しており、
前記ウエザーストリップは、第２取付け部材に取付けられた取付け基部と、この取付け基部と共に中空部を形成していて固定ルーフの開口部側の面に当接可能な中空シール部と、前記取付け基部の下端から突出したリップ部とを一体的に有しており、
前記第１取付け部材の外周部と第２取付け部材の下部の少なくとも一方に、可動パネルの閉鎖時にウエザーストリップと固定ルーフとの間の物の挟み込みを感知するセンサ装着具を装着しており、
前記センサ装着具は、チューブ形状の挟み込み検知用感圧センサを径外方向から挿入して収納可能な断面略Ｃ字状でかつ弾性変形可能な収納感知部と、この収納感知部の両端に一体形成されかつ両方が前記第１取付け部材と第２取付け部材の少なくとも一方に対して装着された両端取付け部とを有しており、
前記センサ装着具の収納感知部を、前記第２取付け部材の下部でウエザーストリップに沿ってかつ前記リップ部の内周側に近接配置していることを特徴とする。
【０００９】
第２に、前記センサ装着具は、収納感知部を発泡ゴムで形成し、両端取付け部を収納感知部より硬質のゴムで形成しており、前記収納感知部は感圧センサの外面に密接しかつ物を挟み込んだときの前記リップ部の変形によって弾性変形可能になっていることを特徴とする。
第３に、前記センサ装着具の両端取付け部を前記第１取付け部材の外周部に対して取付けており、この第１取付け部材の外周部に、物を挟み込んだときに前記リップ部が変形して収納感知部を加圧するときにこの収納感知部をバックアップする円弧形状のカール部分を形成していることを特徴とする。
【００１０】
第４に、前記センサ装着具の両端取付け部の少なくとも一方を、前記第１取付け部材の外周部と第２取付け部材の下部とで挟持して取付けていることを特徴とする。
また、本発明の感圧センサ装置は次のような構成及び作用を有する。
感圧センサ装置は、挟み込みを生じる２部材の一方に、取付け部材８を介してウエザーストリップ９と、このウエザーストリップ９に沿っていて個別形成したセンサ装着具１とを設け、このセンサ装着具１に、挟み込み検知用感圧センサ２を収納した弾性変形可能な収納感知部３を形成していることである。
【００１１】
これによって、収納感知部３を介してチューブ形状の感圧センサ２で、挟み込み時等の種々の方向からの加圧の感知が可能になり、挟み込み検知の信頼性が向上し、感圧センサ２とウエザーストリップ９とは個別に交換可能になる。
感圧センサ装置は、サンルーフ１０の固定ルーフ１１に対して可動する可動パネル１２に、取付け部材８を介してウエザーストリップ９と、このウエザーストリップ９の下側に沿っていて個別形成したセンサ装着具１とを設け、このセンサ装着具１は、チューブ形状の挟み込み検知用感圧センサ２を収納した弾性変形可能な収納感知部３と、この収納感知部３と一体でかつ前記取付け部材８に対して装着された取付け部４とを有していることである。
【００１２】
これによって、収納感知部３を介してチューブ形状の感圧センサ２で、可動パネル１２による挟み込み時の種々の方向からの加圧の感知が可能になり、挟み込み検知の信頼性が向上し、感圧センサ２とウエザーストリップ９とは個別に交換可能になり、取付け部４を介して挟み込み検知が必要な箇所に簡単に取付け可能になる。
【００１３】
前記センサ装着具１の収納感知部３は、挟み込み検知用感圧センサ２を径外方向から挿入可能な断面略Ｃ字状であり、この収納感知部３の両端に取付け部４Ａ、４Ｂを形成して
いることである。
これによって、感圧センサ２の着脱が取付け部４Ａ、４Ｂを開閉するだけで極めて容易にでき、交換等のメンテナンスがやり易くなる。
【００１４】
前記センサ装着具１は、収納感知部３を発泡ゴムで形成し、両端取付け部４Ａ、４Ｂを収納感知部３より硬質のゴムで形成していることである。
これによって、感圧センサ２の感圧感度を良好に維持しながら、取付けを確実にする。
感圧センサ装置は、前記センサ装着具１の両端取付け部４Ａ、４Ｂの少なくとも一方に、芯金１３を埋入していることである。
【００１５】
これによって、両端取付け部４Ａ、４Ｂの保形強度、取付け強度等の向上を図ることができる。
感圧センサ装置は、前記可動パネル１２の外周下面に第１取付け部材８Ａを取付け、前記可動パネル１２の外周縁に第２取付け部材８Ｂを設け、この第２取付け部材８Ｂの外周側にウエザーストリップ９を装着しており、センサ装着具１の両端取付け部４Ａ、４Ｂの一方又は両方を、前記第１、２取付け部材８Ａ、８Ｂで挟持し及び／又は第１、２取付け部材８Ａ、８Ｂの少なくとも一方に係止していることである。
【００１６】
これによって、可動パネル１２の第１、第２取付け部材８Ａ、８Ｂを利用して、センサ装着具１を挟み込み検出に必要な箇所に簡単かつ確実に取付けておくことができる。
感圧センサ装置は、前記可動パネル１２の外周下面に第１取付け部材８Ａを取付け、前記可動パネル１２の外周縁に第２取付け部材８Ｂを設け、この第２取付け部材８Ｂの外周側にウエザーストリップ９を装着しており、センサ装着具１の両端取付け部４Ａ、４Ｂの一方を、断面略Ｃ字状収納感知部３を開いた状態で、前記第１、２取付け部材８Ａ、８Ｂの少なくとも一方に取付け、前記両端取付け部４Ａ、４Ｂの他方を、感圧センサ２挿入後の収納感知部３を閉じながら、第１、２取付け部材８Ａ、８Ｂの一方に取付けていることである。
【００１７】
これによって、センサ装着具１の取付け及び感圧センサ２の着脱が極めて容易になり、装着時に感圧センサ２に不本意な力を加えてダメージを与えるということがない。
前記センサ装着具は、チューブ形状の感圧センサ２を収納した断面略Ｃ字状の収納感知部３と、この収納感知部３の両端に一体的に設けた取付け部４Ａ、４Ｂとを有し、前記収納感知部３を、感圧センサ２に外圧を伝播可能でかつ両取付け部４Ａ、４Ｂの遠近移動で感圧センサ２を径外方向から収納可能な弾性材料で形成している。
【００１８】
このセンサ装着具は、チューブ形状の感圧センサ２を収納した状態で、取付け部４Ａ、４Ｂを介して必要箇所に簡単に取付け、挟み込み等の検知に供することが可能になり、両取付け部４Ａ、４Ｂを遠近移動するだけで感圧センサ２の着脱が可能になる。
【００１９】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図１、２、１８において、１６は乗り物として例示した乗用自動車で、その固定ルーフ１１には開口部１７が形成されており、この開口部１７を可動パネル１２で開閉するサンルーフ１０が設けられている。１８は乗降用開口部、１９は開口部１８を開閉するドアをそれぞれ示している。
【００２０】
このサンルーフ１０は可動パネル１２をチルト動作するだけのもの、チルトアップ動作又はチルトダウン動作した後に後方へスライドするもの、固定ルーフ１１の上側に位置してスライド動作だけをするもの等、いずれであってもよい。
前記サンルーフ１０の可動パネル１２は透明又は色付のガラスで形成されており、この可動パネル１２の外周部には室内側の面に第１取付け部材（ガラスサポート）８Ａが、この第１取付け部材８Ａよりさらに外側の外周縁には第２取付け部材８Ｂがそれぞれ接着されている。
【００２１】
第１取付け部材８Ａは、板金で四角枠を形成し、プレスで凹凸変形させたものであり、第２取付け部材８Ｂは合成樹脂で四角枠形状に形成され、その断面形状において、立部８ａと脚部８ｂと突出部８ｃとを有し、立部８ａと脚部８ｂとで可動パネル１２と接着し、脚部８ｂと突出部８ｃとでウエザーストリップ（シール部材）９を取付けている。
【００２２】
前記第２取付け部材８Ｂの全周囲に沿って設けられたウエザーストリップ９は、脚部８ｂと突出部８ｃとに接着されるソリッドゴム製の取付け基部９ａと、この取付け基部９ａと共に中空部を形成するスポンジゴム製の中空シール部９ｂと、取付け基部９ａの下端から突出していてソリッドゴム又はそれより硬度の低いゴムで形成されたリップ部９ｃとを一体的に有している。
【００２３】
なお、本発明における接着とは、両面接着テープによるもの、接着剤によるもの等の種々の接着手段を含んで意味する。
このウエザーストリップ９は、中空シール部９ｂが固定ルーフ１１の開口部１７側の面に弾力的に当接して、可動パネル１２と固定ルーフ１１との間のシールをする。
【００２４】
前記可動パネル１２に対する第２取付け部材８Ｂの取付けには、第１取付け部材８Ａも関与することがある。前記第１取付け部材８Ａは、可動パネル１２の補強をすると共に、左右リフタの取付けに利用され、可動パネル１２は左右リフタを介して固定ルーフ１１に設けられる左右ガイドレールに前後摺動自在にかつ昇降自在に支持されることになる。２０は左右ガイドレールを支持し、樋部２１及び車室側開口２２を形成するサンルーフ１０の支持フレームを示している。
【００２５】
前記第１取付け部材８Ａの外周、第２取付け部材８Ｂの立部８ａの下部及びウエザーストリップ９で挟まれる位置に、挟み込み検知用感圧センサ装置７が設けられている。この感圧センサ装置７は可動パネル１２の全周囲に設けられている。
図１、２に示す第１の実施の形態において、感圧センサ２をセンサ装着具１Ａに取付け、このセンサ装着具１Ａをウエザーストリップ９の下側に沿って配置して、前記第１取付け部材８Ａと第２取付け部材８Ｂとで挟持している。
【００２６】
センサ装着具１Ａは、チューブ形状の感圧センサ２を収納した断面略Ｃ字状の弾性変形可能な収納感知部３と、この収納感知部３の両端に一体的に設けた取付け部４Ａ、４Ｂとを有する。
感圧センサ２は、一方向からの加圧だけでなく、種々の方向の加圧でも検出できるものであり、前記第２従来技術で示した感知チューブセンサの他、弾性変形可能なチューブ内に２電極を螺旋状に巻き回配置したもの等の公知のものが使用される。
【００２７】
前記収納感知部３は発泡ゴム（前記中空シール部９ｂと同様なスポンジゴム又は感圧センサ２のチューブと同一材料）で形成しており、円筒に軸線方向と平行なスリット３ａを入れた形状、すなわち断面Ｃ字形状であり、スリット３ａを形成する両端部に取付け部４Ａ、４Ｂが形成されており、この両端取付け部４Ａ、４Ｂは、収納感知部３より硬質のゴム（前記取付け基部９ａと同様なソリッドゴム）で形成している。
【００２８】
この両端取付け部４Ａ、４Ｂを遠近移動することにより、断面略Ｃ字状の収納感知部３は開閉され、開放状態で径外方向から感圧センサ２を挿脱することができ、閉鎖することにより、収納感知部３は感圧センサ２の外面に密接し、収納感知部３に加わる外力を感圧センサ２に伝播可能になっている。
前記第１取付け部４Ａは凹部４ａと係止部４ｂとを有し、第２取付け部４Ｂは前記凹部４ａに嵌合可能な凸部４ｃを有し、この第２取付け部４Ｂの凸部４ｃを第１取付け部４Ａの凹部４ａに嵌合した状態で、両端取付け部４Ａ、４Ｂは閉鎖状態となり、その状態で第１取付け部材８Ａの外周と第２取付け部材８Ｂの立部８ａの下部とで挟むことにより取付けられることになり、しかもその挟持状態で第１取付け部４Ａの係止部４ｂが立部８ａの下部と係合し、挟持状態からの抜け止めがなされる。
【００２９】
この取付け状態で、センサ装着具１Ａの収納感知部３は、第１取付け部材８Ａの外周のカール部分８ｅとウエザーストリップ９のリップ部９ｃに当接していて、ウエザーストリップ９と固定ルーフ１１との間で手、指、その他の物を挟んだときに、リップ部９ｃが変形して収納感知部３を加圧し、第１取付け部材８Ａが収納感知部３をバックアップするようになっている。
【００３０】
但し、収納感知部３は第１取付け部材８Ａ及びリップ部９ｃと当接しなくとも、両端取付け部４Ａ、４Ｂによる支持があるので、挟み込みを検出することは可能である。また、凹部４ａ及び凸部４ｃは、それぞれ第１、２取付け部４Ａ、４Ｂの全長に亘る長い溝、凸条になっているが、間隔をおいて位置する凹み、突起であってもよい。
【００３１】
前記第１の実施の形態の感圧センサ装置７の製作において、両端取付け部４Ａ、４Ｂを押し開いて収納感知部３に径外方向から感圧センサ２を挿入し、両端取付け部４Ａ、４Ｂを閉じて感圧センサ２を収納感知部３で抱き込む用に収納し、その状態で、両端取付け部４Ａ、４Ｂを第２取付け部材８Ｂの立部８ａの下部に当てがい、かつその下側から第１取付け部材８Ａを当接させ、この第１取付け部材８Ａを可動パネル１２に接着する。
【００３２】
なお、可動パネル１２に第１、２取付け部材８Ａ、８Ｂを予め取付けておいて、立部８ａとカール部分８ｅとの間の隙間に、外方から両端取付け部４Ａ、４Ｂを挿入して、可動パネル１２にセンサ装着具１を取付けるようにすることも可能である。
可動パネル１２の閉鎖時にウエザーストリップ９と固定ルーフ１１との間に物を挟み込むと、ウエザーストリップ９の中空シール部９ｂが変形した後にリップ部９ｃの変形により、又は挟み込み物により直接的に、収納感知部３が押されて弾性変形し、その外力による変形がそのまま感圧センサ２に伝播され、挟み込みを検出して可動パネル１２の駆動装置を停止する。
【００３３】
前記収納感知部３は４分の３円前後の円周を有するので、収納されている感圧センサ２は外力反応方向域が広く、感知精度が高くなっており、挟み込み物を確実に検知する。
また、センサ装着具１はウエザーストリップ９の下方に配置されているので、風雨に晒されることがなく、外部の温度変化の影響も少なく、可動パネル１２の開閉時に収納感知部３が変形されることがなく、よって故障することも少なくなっている。
【００３４】
感圧センサ２が損傷した場合、ウエザーストリップ９をそのままにしておいて、センサ装着具１と第１取付け部材８Ａを可動パネル１２から取り外す。センサ装着具１は取り外すと簡単に開放されるので、感圧センサ２のみを簡単に交換できる。
ウエザーストリップ９が損傷した場合、センサ装着具１をそのままにしておいて、ウエザーストリップ９のみを第１取付け部材８から引き剥がし、新品のものを第１取付け部材８に巻き付けて接着する。
【００３５】
図３、４に示す第２の実施の形態において、感圧センサ２をセンサ装着具１Ｂに取付け、このセンサ装着具１Ｂをウエザーストリップ９の下側に沿って配置し、第２取付け部４Ｂを前記第１取付け部材８Ａと第２取付け部材８Ｂとで挟持している。
センサ装着具１Ｂは、第１取付け部４Ａが帯板状であるが、第２取付け部４Ｂが断面略Ｊ字状をしており、その内部に芯金１３が埋設されており、第２取付け部４Ｂのコーナ部分には凹部４ｄが形成され、第１取付け部材８Ａの跳ね上がり外周縁８ｆと係合している。
【００３６】
このセンサ装着具１Ｂは、第２取付け部４Ｂを第１取付け部材８Ａの跳ね上がり外周縁８ｆに嵌合した状態で、第１取付け部材８Ａと第２取付け部材８Ｂとで挟持固定し、その状態で断面略Ｃ字状収納感知部３を開いた状態となり、感圧センサ２が挿入でき、そして、感圧センサ２を挿入後に収納感知部３を閉じながら、第１取付け部４Ａを第１取付け部材８Ａの下面に接着することにより取付けられる構造となっている。
【００３７】
従って、感圧センサ２は収納感知部３を開いた状態で挿入するので、無理な力で押しつける等の不本意な力を加えることがなく、また、第１取付け部４Ａを第１取付け部材８Ａの下面に着脱すことにより、感圧センサ２を交換することができ、装着時及び交換時に感圧センサ２にダメージを与えることがない。
なお、前記芯金１３は第１取付け部材８Ａに対する第２取付け部４Ｂの保形強度及び取付け強度を増大するために設けられており、第１取付け部４Ａにも芯金を埋入してもよい。
【００３８】
図５、６に示す第３の実施の形態において、感圧センサ２をセンサ装着具１Ｃに取付け、このセンサ装着具１Ｃをウエザーストリップ９の下側に沿って配置し、第１取付け部４Ａを第１取付け部材８Ａに嵌着し、第２取付け部４Ｂを前記第１取付け部材８Ａと第２取付け部材８Ｂとで挟持すると共に第２取付け部材８Ｂに係止している。
【００３９】
センサ装着具１Ｃは、第１取付け部４Ａが渦巻き状に巻かれており、この渦巻き部４ｅが第１取付け部材８Ａのカール部分８ｅに巻き込んで嵌着されており、第２取付け部４Ｂが第１取付け部材８Ａと第２取付け部材８Ｂとで挟まれていて、立部８ａと係合する係止部４ｆを有している。
【００４０】
従って、前記センサ装着具１Ｃは、第１取付け部４Ａを第１取付け部材８Ａのカール部分８ｅに嵌着しておいて、この第１取付け部材８Ａを可動パネル１２に取付けながら、第２取付け部４Ｂを第２取付け部材８Ｂに押し当てるようにしている。但し、第２取付け部４Ｂを第１取付け部材８Ａに接着すれば、第１取付け部材８Ａによる挟持がなくとも取付けておくことができる。
【００４１】
図７、８に示す第４の実施の形態において、感圧センサ２を取付けるセンサ装着具１Ｄは実質的に第１取付け部材８Ａに取付けられ、第２取付け部材８Ｂは収納感知部３の当たり面のみを形成している。
センサ装着具１Ｄは、第１取付け部４Ａに間隔をおいて係合突起４ｇが形成されていて、第１取付け部材８Ａに形成された孔８ｇに係合しており、第２取付け部４Ｂには嵌合部４ｈが形成されていて、第１取付け部材８Ａの外周立ち上がり部８ｈに嵌合しており、しかも第１取付け部４Ａと第２取付け部４Ｂとは第１取付け部材８Ａに接着されている。
【００４２】
なお、前記嵌合部４ｈは第１取付け部材８Ａの外周立ち上がり部８ｈと第２取付け部材８Ｂの立部８ａとで挟持したり、収納感知部３をウエザーストリップ９のリップ部９ｃのみに当接するようにしてもよい。
図９は前記第４の実施の形態のセンサ装着具１Ｄの変形例を示している。可動パネル１２の後部側の下方にはドリップレール２４が配置されていて、開口部１７を開放するために可動パネル１２を下降すると、第１取付け部材８Ａがドリップレール２４と干渉する恐れがあり、そのため、第１取付け部材８Ａの上下寸法を小さくし、第１取付け部材８Ａの外周の下面と第２取付け部材８Ｂの立部８ａの下面との段差を少なくしている。
【００４３】
そのため、可動パネル１２の後部のセンサ装着具１Ｅは、収納感知部３が第１取付け部４Ａよりも下方へ突出した形状となっており、嵌合部４ｈの高さが低くなっている。
なお、このセンサ装着具１Ｅは、可動パネル１２の全周に設けてもよく、前記センサ装着具１Ｄと組み合わせて使用することもでき、また、ひとつのセンサ装着具１を可動パネル１２の前側から後側へ次第にセンサ装着具１Ｄからセンサ装着具１Ｅへ変化させて一体形成することもできる。
【００４４】
前記センサ装着具１Ｃ、１Ｄ、１Ｅにおいても、前記第２の実施の形態のセンサ装着具１Ｂと略同様に、両端取付け部４Ａ、４Ｂの一方を、断面略Ｃ字状収納感知部３を開いた状態で、前記第１、２取付け部材８Ａ、８Ｂの少なくとも一方に嵌合、係合又は挟持で取付け、前記両端取付け部４Ａ、４Ｂの他方を、感圧センサ２挿入後の収納感知部３を閉じながら、第１、２取付け部材８Ａ、８Ｂの一方に嵌合、係合又は接着で取付けることが可能である。
【００４５】
従って、感圧センサ２にダメージを与えることもなく、装着及び交換を簡単かつ容易に行える。
図１０、１１に示す第５の実施の形態において、感圧センサ２を取付けるセンサ装着具１Ｆは実質的に第２取付け部材８Ｂに取付けられ、第１取付け部材８Ａは第１取付け部４Ａの押さえをしている。
【００４６】
第２取付け部材８Ｂには脚部８ｂから下方へ断面略Ｊ字形状の掛合部８ｊが突設されており、センサ装着具１Ｆの第２取付け部４Ｂには、掛合部８ｊに嵌合する嵌合部４ｈが形成され、第１取付け部４Ａには、掛合部８ｊの内周側と係合する係止部４ｂが形成されている。
前記第１取付け部４Ａ及び第２取付け部４Ｂは、掛合部８ｊに嵌合すると同時に接着されており、第１取付け部材８Ａの外周は第１取付け部４Ａを掛合部８ｊと挟持している。
【００４７】
図１２、１３に示す第６の実施の形態において、感圧センサ２を取付けるセンサ装着具１Ｇは第２取付け部材８Ｂのみに取付けられ、第１取付け部材８Ａはセンサ装着具１Ｇの取付けには関与していない。
第２取付け部材８Ｂの脚部８ｂは下方へ長く形成されていて、可動パネル１２の周方向に間隔をおいて係合孔８ｋが多数設けられており、センサ装着具１Ｇの第１、２取付け部４Ａ、４Ｂには、前記係合孔８ｋに嵌入されるカエリ付き突起４ｋが形成されている。
【００４８】
前記センサ装着具１Ｇは、カエリ付き突起４ｋを係合孔８ｋに嵌入することにより、第２取付け部材８Ｂの脚部８ｂに取付けられ、収納感知部３を第１、２取付け部４Ａ、４Ｂでバックアップしながらリップ部９ｃに当接し、固定ルーフ１１と可動パネル１２との間にものが挟まれたときにそれを検出する。
図１４、１５に示す第７の実施の形態において、感圧センサ２を取付けるセンサ装着具１Ｈは第１取付け部材８Ａのみに取付けられ、第２取付け部材８Ｂはセンサ装着具１Ｈの取付けには関与していない。
【００４９】
第２取付け部材８Ｂは立部、脚部及び突出部の区別がなく断面略コの字形状で、合成樹脂又はゴムで形成され、その外周面にウエザーストリップ９を接着又は加硫接着しており、第１取付け部材８Ａの外周立ち上がり部８ｈによって補助固定されている。
前記第１取付け部材８Ａの外周下面には、その外周に沿って長い又は間隔をおいて多数の取付けブラケット２６が固着されており、この第１取付け部材８Ａと取付けブラケット２６とでセンサ装着具１Ｈが挟持されている。
【００５０】
センサ装着具１Ｈは、収納感知部３の両端に一体に設けた第１、２取付け部４Ａ、４Ｂにそれぞれカエリ部４ｍが形成されており、上下のカエリ部４ｍは第１取付け部材８Ａの段部８ｍと取付けブラケット２６の段部２６ａとにそれぞれ係合可能である。

A pinching detection pressure-sensitive sensor device 7 is provided at a position sandwiched between the outer periphery of the first mounting member 8A, the lower portion of the upright portion 8a of the second mounting member 8B, and the weather strip 9. The pressure sensitive sensor device 7 is provided all around the movable panel 12.
In the first embodiment shown in FIGS. 1 and 2, the pressure-sensitive sensor 2 is attached to the sensor mounting tool 1A, and the sensor mounting tool 1A is arranged along the lower side of the weather strip 9 so that the first mounting member is arranged. 8A and the second mounting member 8B are sandwiched.

The sensor mounting tool 1A includes an elastically deformable storage sensing portion 3 that houses a tube-shaped pressure-sensitive sensor 2, and mounting portions 4A and 4B that are integrally provided at both ends of the storage sensing portion 3. And have.
The pressure-sensitive sensor 2 can detect not only pressure from one direction but also pressure in various directions. In addition to the sensing tube sensor shown in the second prior art, the pressure-sensitive sensor 2 is provided in an elastically deformable tube. A well-known thing such as one in which two electrodes are spirally arranged is used.
[0027]
The storage sensing unit 3 is formed of foamed rubber (sponge rubber similar to the hollow seal portion 9b or the same material as the tube of the pressure-sensitive sensor 2), and has a shape in which a slit 3a parallel to the axial direction is inserted in a cylinder, That is, it has a C-shaped cross section, and mounting portions 4A and 4B are formed at both ends forming the slit 3a. The both end mounting portions 4A and 4B are harder than the storage sensing portion 3 (the mounting base portion 9a and the mounting base portion 9a). The same solid rubber).
[0028]
By moving the both end mounting portions 4A and 4B in the near and far directions, the storage sensing portion 3 having a substantially C-shaped cross section is opened and closed, and the pressure sensitive sensor 2 can be inserted and removed from the radially outward direction in the open state, and is closed. Accordingly, the storage sensing unit 3 is in close contact with the outer surface of the pressure sensor 2, and an external force applied to the storage sensor 3 can be transmitted to the pressure sensor 2.
The first mounting portion 4A has a concave portion 4a and a locking portion 4b, and the second mounting portion 4B has a convex portion 4c that can be fitted into the concave portion 4a. The convex portion 4c of the second mounting portion 4B.

[0029]
In this attached state, the storage sensing portion 3 of the sensor mounting tool 1A is in contact with the curled portion 8e on the outer periphery of the first attachment member 8A and the lip portion 9c of the weather strip 9, and the weather strip 9 and the fixed roof 11 are in contact with each other. When a hand, finger, or other object is sandwiched between them, the lip portion 9c is deformed to pressurize the storage sensing unit 3, and the first attachment member 8A backs up the storage sensing unit 3.
[0030]
However, since the storage sensing unit 3 is supported by the both end mounting portions 4A and 4B without contacting the first mounting member 8A and the lip portion 9c, it is possible to detect pinching. Moreover, although the recessed part 4a and the convex part 4c are the long groove | channel and convex strip over the full length of 1st, 2 attachment part 4A, 4B, respectively, the dent and protrusion which are located in intervals may be sufficient.
[0031]
In manufacturing the pressure-sensitive sensor device 7 of the first embodiment, the both-end mounting portions 4A and 4B are pushed open to insert the pressure-sensitive sensor 2 into the storage sensing portion 3 from the radially outward direction, and the both-end mounting portions 4A and 4B. And the pressure sensor 2 is housed for embedding by the housing sensing part 3, and in this state, both end attachment parts 4A, 4B are applied to the lower part of the upright part 8a of the second attachment member 8B, and the lower side The first mounting member 8A is brought into contact with the first mounting member 8A, and the first mounting member 8A is bonded to the movable panel 12.

The first and second mounting members 8A and 8B are mounted in advance on the movable panel 12, and the both end mounting portions 4A and 4B are inserted from the outside into the gap between the standing portion 8a and the curled portion 8e. It is also possible to attach the sensor mounting tool 1 to the movable panel 12.
If an object is sandwiched between the weather strip 9 and the fixed roof 11 when the movable panel 12 is closed, the hollow seal portion 9b of the weather strip 9 is deformed and then deformed by the lip portion 9c or directly by the sandwiched object. The sensing unit 3 is pushed and elastically deformed, and the deformation due to the external force is directly transmitted to the pressure-sensitive sensor 2 to detect pinching and stop the driving device of the movable panel 12.
[0033]
Since the storage sensing unit 3 has a circumference of about three-quarters of a circle, the stored pressure sensor 2 has a wide external force reaction direction range and high detection accuracy, and reliably detects pinched objects. .
Further, since the sensor mounting device 1 is disposed below the weather strip 9, it is not exposed to wind and rain, is less affected by external temperature changes, and the storage sensing unit 3 is deformed when the movable panel 12 is opened and closed. Therefore, it is less likely to break down.
[0034]
When the pressure-sensitive sensor 2 is damaged, the weather strip 9 is left as it is, and the sensor mounting tool 1 and the first attachment member 8A are removed from the movable panel 12. Since the sensor mounting tool 1 is easily opened when it is removed, only the pressure sensor 2 can be easily replaced.
