【発明の属する技術分野】
本発明は、車両の動力付窓開閉装置(例えば、パワーウインド)に係り、特に挟み込み防止機構を有する動力付窓開閉装置に関するものである。
【0002】
従来、挟み込み防止機構を有するパワーウインド構造として、外力を感知する感圧センサ等の感知手段を窓枠に沿って配設し、窓ガラスと窓枠との間の異物挟み込みによる外力を、この感知手段により検出して窓ガラスの開方向への移動を中止するものが知られている。(例えば、実開昭64−53389号公報)
【0003】
しかし、従来の挟み込み防止機構によれば、窓ガラスと窓枠との間に異物が挟み込まれているにもかかわらず、挟み込みを検出できない場合がある。つまり、図8に示すように、車室外側の窓枠に沿って設けられたサイドバイザー105の先端105aと窓ガラス102との間に異物Dが挟み込まれた場合、車室内の窓枠103(ウエザストリップ)に感圧センサ110が配設されているにもかかわらず、異物Dが窓枠103の他の部位(感圧センサ110が配設されていない部位)を押圧し、上記感圧センサ110が押圧されないため異物Dの挟み込みを検出できない。仮に、感圧センサ110を押圧できたとしても外力の作用する方向によっては所定以上の押圧力が得られず、挟み込みを確実に検出できない。上記問題はサイドバイザーが大型化するにつれて著しく発生する。
【0004】
そこで、従来の挟み込み防止機構にて、外力の作用方向に対して広い検知範囲で異物の挟み込み検出をしようとすると、感圧センサ自体を大きくする必要がある。しかし、感圧センサを大きくすると窓枠への配置が困難になるばかりか、感圧センサ自体の剛性が高くなり、低い挟み込み荷重を確実に検出することができなくなるといった問題が生じる。
【0005】
【発明が解決しようとする課題】
そこで、本発明は外力の作用方向にかかわらず確実に挟み込みを検出することができる動力付窓開閉装置を提供することを目的としている。
【0006】
【課題を解決するための手段】
上記課題を解決するために、本発明の請求項1記載の動力付窓開閉装置は、窓枠(3)によって形成される窓開口(3a)を開閉する窓体(2)と、前記窓枠(3)の車室外側周縁に沿って配設されたサイドバイザー(5)と、前記窓枠の車室内側周縁に沿って配設され前記窓体(2)と前記窓枠(3)との間に挟み込まれた異物(B,C)が受ける外力を感知する第1の感知手段(42)と、前記窓枠の車室内側周縁に沿って前記第1の感知手段(42)に対して所定間隔を有して平行に配設され、前記窓体(2)と前記サイドバイザー(5)および前記窓枠(3)との間に挟み込まれた異物(A)が受ける外力を感知すると共に、前記窓体(2)と前記窓枠(3)との間に挟み込まれた異物(C)が受ける外力を感知する第2の感知手段(44)と、前記第1及び第2の感知手段のうち、少なくとも一つの感知手段によって感知される外力が所定値を越えたときに、前記窓体の閉方向への移動を中止する閉移動中止手段(1,6)とを有することを特徴としている。
【0007】
請求項1記載の動力付窓開閉装置によれば、窓枠の車室内側周縁に沿って配設され窓体(2)と窓枠(3)との間に挟み込まれた異物(B,C)が受ける外力を感知する第1の感知手段(42)と、窓枠の車室内側周縁に沿って第1の感知手段(42)に対して所定間隔を有して平行に配設され、窓体(2)とサイドバイザー(5)および窓枠(3)との間に挟み込まれた異物(A)が受ける外力を感知すると共に、窓体(2)と前記窓枠(3)との間に挟み込まれた異物(C)が受ける外力を感知する第2の感知手段(44)と、を備えており、少なくとも一つの感知手段が外力を感知すると窓体の閉方向への移動を中止する。すなわち、窓枠に沿って複数の感知手段を設けることによって、外力の作用方向に対して挟み込みの検出可能範囲が広がり、外力の作用方向にかかわらず確実に挟み込みを検出することができる。
【0008】
請求項2記載の動力付窓開閉装置は、窓枠(3)によって形成される窓開口(3a)を開閉する窓体(2)と、前記窓枠(3)の車室外側周縁に沿って配設されたサイドバイザー(5)と、前記窓枠の車室内側周縁に沿って配設され前記窓体(2)と前記窓枠(3)との間に挟み込まれた異物(B,C)が受ける外力を感知する第1の感知手段(42)と、前記窓枠の車室内側周縁に沿って前記第1の感知手段(42)に対して所定間隔を有して平行に配設され、前記窓体(2)と前記サイドバイザー(5)および前記窓枠(3)との間に挟み込まれた異物(A)が受ける外力を感知すると共に、前記窓体(2)と前記窓枠(3)との間に挟み込まれた異物(C)が受ける外力を感知する第2の感知手段(44)と、前記窓体を開閉移動させる窓体駆動手段(1)と、前記窓体駆動手段の過負荷信号を検知する駆動負荷検出手段(12)と、前記第1及び第2の感知手段のうち、少なくとも一つの感知手段によって感知される外力が所定値を越え、かつ駆動負荷検出手段によって検出される外力が所定値を越えたときに、前記窓体の閉方向への移動を中止する閉移動中止手段(1,6)とを有することを特徴としている。
【0009】
請求項2記載の動力付窓開閉装置によれば、窓枠の車室内側周縁に沿って配設され窓体(2)と窓枠(3)との間に挟み込まれた異物(B,C)が受ける外力を感知する第1の感知手段(42)と、窓枠の車室内側周縁に沿って第1の感知手段(42)に対して所定間隔を有して平行に配設され、窓体(2)とサイドバイザー(5)および窓枠(3)との間に挟み込まれた異物(A)が受ける外力を感知すると共に、窓体(2)と前記窓枠(3)との間に挟み込まれた異物(C)が受ける外力を感知する第2の感知手段(44)と、を備えており、少なくとも一つの感知手段によって感知される外力が所定値を越え、かつ駆動負荷検出手段によって検出される外力が所定値を越えたときに、前記窓体の閉方向への移動を中止しているから、外力の作用方向に対して挟み込みの検出可能範囲が広がると共に、悪戯等による誤作動が生じることなく、窓体への異物の挟み込みを確実に回避することができる。
【0012】
さらに、請求項記載の動力付窓開閉装置は、前記第1の感知手段(42)及び前記第2の感知手段(44)は、室内側において可撓性を有する絶縁部材(8,9,48)により一体的に保持されていることを特徴としている。
【0013】
請求項記載の動力付窓開閉装置によれば、第1の感知手段(42)及び第2の感知手段(44)は、室内側において絶縁部材により一体的に保持されているため、感知手段を同時に窓枠に配設することができ、窓枠への取り付けが容易となる。また、複数の感知手段の互いの距離を所定間隔に保持することができる。
【0015】
なお、上記手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。
【0016】
【発明の実施の形態】
〔第1実施形態〕
以下、本発明における第1実施形態を図面に基づいて説明する。
図1は、挟み込み防止機構を有する動力付窓開閉装置(パワーウインド機構)を備えた車両ドアを示しており、1は窓開口3aを開閉する窓ガラス2を昇降駆動させる駆動モータであり、3は窓開口3aを区画する窓枠である。この窓枠3の車室内側の周縁には、外力を感知する感圧センサ42,44(感知手段)が窓枠3の前辺部3bから上辺部3cに渡ってそれぞれ配設されている。また、窓枠3の車室外側の周縁には、サイドバイザー5が取り付けられている。因みに、感圧センサ42,44は、車室外側に設けると劣化しやすいため車室内側に設けられている。
【0017】
これら感圧センサ42,44は、それぞれ独立した感圧機能を有している。つまり、感圧センサ42,44の検知レベルは互いに異なるように設定されている。感圧センサ42,44の少なくとも一方に所定値以上の外力が作用すると感圧信号42a(44a)を発する。そして、感圧信号42a(44a)が発せられると、この感圧信号42a(44a)は制御装置6に入力され、感圧信号42a(44a)を受けて制御装置6が、駆動モータ1に対して窓ガラス2を反転(下降)させるように反転信号6aを発する。以上に述べた構成により、窓ガラス2の閉方向移動を中止する閉移動中止手段を構成している。
【0018】
さらに、図2に示すように、窓枠3には、当該窓枠3に沿って車室内側に設けられ窓ガラス2と窓枠3との隙間を密閉するウエザストリップ7が設けられている。そして、このウエザストリップ7に固定された絶縁部材から成る弾性発泡体8の内部に互いに平行となるように感圧センサ42,44が一体的に配設されている。
【0019】
詳しくは、窓ガラス2の開閉方向と交差する方向に所定間隔を有して感圧センサ42,44が窓枠3に沿って平行に配設されている。そして、窓ガラス2から垂直に延ばした感圧センサ42までの距離L1と、窓ガラス2から垂直に延ばした感圧センサ44までの距離L2との関係はL1<L2とされている。なお、7aおよび7bはウエザストリップ7の機械的な強度を増すための金属製の芯材で通常この芯材は窓枠3の断面形状に沿うように屈曲している。
【0020】
以下に、感圧センサ42,44の構造を説明する。
本実施形態において、感圧センサ42,44は互いに検知レベルが異なるものの、共に同じ構造であるため感圧センサ42の構造のみ説明する。
【0021】
感圧センサ42は、図3に示すように、可撓性を有する絶縁材料からなる長尺状のチューブ41の内周壁に、チューブ41の長手方向に延びるとともに、チューブ41内で所定距離を有して対向する導電性ゴム材料からなる2つの帯板状電極43,45を設けたものである。
【0022】
そして、両帯板状電極43,45の対向面43a,45aの間には、絶縁部をなす空隙46が形成されている。両帯板状電極43,45間には所定電圧が印加されており、所定以上の外力が作用するとチューブ41が変形し、チューブ41の変形に伴って対向面43a,45aが接触する。そして、対向面43a,45aが接触した際に互いが導通され上記感圧信号42aが発せられる。同様に、感圧センサ44に所定以上の外力が作用すると上記感圧信号44aが発せられるようになっている。
【0023】
なお、感圧センサ42,44のチューブ41を廃止してウエザストリップ7に両帯板状電極43,45を一体的に配置してもよい。
【0024】
次に、本実施形態の特徴を述べる。
本実施形態によれば、ウエザストリップ7には2本の感圧センサ42,44が窓枠3に沿って平行配設されている。そして、感圧センサ42,44のうち、少なくとも一方が外力を感知すると窓ガラス2の閉方向への移動を中止するように制御装置6に対して感圧信号を発する。
【0025】
つまり、図4に示すように、窓ガラス2の閉作動中に、窓ガラス2とサイドバイザー5の先端5aおよびウエザストリップ7(弾性発泡体8)との間に異物Aが挟み込まれた場合、感圧センサ44が外力を検出して、上述した閉移動中止手段により窓ガラス2が開作動する。
【0026】
また、窓ガラス2の閉作動中に、窓ガラス2とウエザストリップ7(弾性発泡体8)との間に異物Bが挟み込まれた場合、感圧チューブセンサ42が外力を検出して閉移動中止手段により窓ガラス2が開作動する。
【0027】
さらに、窓ガラス2とウエザストリップ7との間に異物Cが挟み込まれた場合には、感圧チューブセンサ42,44が共に外力を感知して閉移動中止手段により窓ガラス2が開作動する。
【0028】
即ち、窓枠3に沿って2本の感圧センサ42,44を設けることによって、異物挟み込みの検出可能範囲が広がるため、車室外側の窓枠3にサイドバイザー5が取り付けられているような場合にも、外力の作用方向にかかわらず確実に挟み込みを検出することができる。
【0029】
また、本実施形態のように、2本の感圧センサ42,44がウエザストリップ7内に配置されているため、感圧センサ42,44の間隔を所定の間隔に保つことができ、かつ容易に取り付けることができる。
【0030】
さらに、図5に示すように、ウエザストリップを介さず感圧センサ42,44を窓枠3に直接取り付ける場合、可撓性を有する絶縁部材等(弾性ゴム9)にて感圧センサ42,44を一体的に保持し、弾性ゴム9の一部をネジ10等によって金属製の芯材7cに固定することによって窓枠3側に容易に取り付けることができる。また、接着材によって弾性ゴム9を芯材7cに固定してもよい。さらに、図6に示すように、感圧センサ42,44をチューブ48にて一体的に保持して弾性ゴム11内に収納する構成としてもよい。
【0031】
〔第2実施形態〕
次に、本発明における第2実施形態を説明する。なお、上記第1実施形態と同じ部材には同符号を付す。
図7に、第2実施形態に係る動力付窓開閉装置の全体構造を示す。図において、車両ドアには窓ガラス2を昇降駆動させる駆動モータ1が設けられており、駆動モータ1の正逆転は、制御装置6を成すモータ反転回路60aでモータ端子への通電極性を変更することにより行われる。駆動モータ1には、駆動モータ1の回転数を検出する回転数センサ12(駆動負荷検出手段)が設けられており、回転数センサ12からの過負荷信号1aは、ANDゲート51に入力しており、この過負荷信号1aは、駆動モータ1の回転数が所定値を下回ったことにより発せられる。なお、5はサイドバイザーを示す。
【0032】
一方、車両ドアの車室内側のウエザストリップ7内には、2つの感圧センサ42,44が互いに平行に敷設されている。これら感圧センサ42,44からの感圧センサ信号42a,44aは、ORゲート50に入力している。また、ORゲート50からの出力信号は上記ANDゲート51に入力される。
【0033】
さらに、ANDゲート51には、窓閉鎖中信号61aが入力している。この窓閉鎖中信号61aは、例えば、モータ端子の極性により、モータ正転(窓ガラス閉鎖方向)時に発せられる。ANDゲート51の出力は制御装置6を成すコントロール回路60bへ入力している。コントロール回路60bは操作スイッチ80の指令に応じてモータ反転回路60aを作動させ、モータ反転回路60aはバッテリ70からの直流電圧の極性を適宜切り替えて駆動モータ1へ印加することにより当該モータ1を正逆転させる。
【0034】
そして、上記コントロール回路60bは、ANDゲート51からの出力信号を入力した時、すなわち、窓ガラス閉鎖作動中において、2つの感圧センサ42,44のうち、少なくとも一方から出力信号(感圧センサ信号42aあるいは44a)が発せられ、かつモータ過負荷信号1aが発せられると、即座にコントロール回路60bに指令信号を発して、モータ反転回路60aを介して駆動モータ1に反転信号6aを発し窓ガラス開放方向へ逆転させる。
【0035】
本第2実施形態によれば、窓ガラスの閉鎖作動中にのみ、少なくとも一つの感圧センサ信号とモータ過負荷信号とのAND条件から出力を確認しているから、外力の作用方向に対して挟み込みの検出可能範囲が広がると共に、悪戯等による誤作動が生じることなく、窓ガラスへの異物の挟み込みを確実に回避することができる。
【0036】
上記実施形態において、2つの感圧センサ42,44を窓枠(ウエザストリップ)に沿って平行に配設した例を用いて説明したが、これに限らず、外力の作用する角度の範囲に応じて感圧センサの数を3つ、4つ或いはそれ以上としてもよく、感圧センサの数は特に限定されるものではない。また、感圧センサ42,44の検知レベルを異なるものとしたが、同じ検知レベルに設定してもよい。
【0037】
また、窓開閉方向に対する各感圧センサ42,44の取り付け角度や感圧センサ42,44の互いの間隔は、窓枠に沿って適宜変更してもよく、これにより、窓枠に沿った各所で感圧検知角度の範囲を変更することができる。
【0038】
さらに、上記感圧センサ42のような対向する帯板状電極43,45同士の導通により外力を検知するタイプのセンサに限らず、例えば、外力の作用により内部抵抗が変化するタイプの抵抗変化式の感圧センサを用いたり、あるいは内部圧力の変化により外力を検知するタイプの感圧センサを用いてもよく、公知の様々な感圧センサを適用することができ、感圧センサの構造は特に限定されるものではない。
【0039】
【発明の効果】
以上説明したように、本発明の動力付窓開閉装置は、窓枠に沿って複数の感圧センサを設けた構成としたので、異物挟み込みの検出可能範囲が広がり、外力の作用方向にかかわらず確実に挟み込みを検出することができるといった優れた効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a powered window opening / closing device (for example, a power window) of a vehicle, and more particularly to a powered window opening / closing device having a pinching prevention mechanism.
[0002]
Conventionally, as a power window structure having a pinching prevention mechanism, a sensing means such as a pressure sensor that senses an external force is provided along the window frame, and this external force due to foreign object pinching between the window glass and the window frame is detected. What detects by a means and stops the movement to the opening direction of a window glass is known. (For example, Japanese Utility Model Publication No. 64-53389)
[0003]
However, according to the conventional pinching prevention mechanism, pinching may not be detected even though a foreign object is pinched between the window glass and the window frame. That is, as shown in FIG. 8, when a foreign substance D is sandwiched between the front end 105a of the side visor 105 provided along the window frame outside the vehicle compartment and the window glass 102, Although the pressure sensor 110 is disposed on the strip), the foreign matter D presses another part of the window frame 103 (part where the pressure sensor 110 is not disposed), and the pressure sensor Since 110 is not pressed, it is not possible to detect the trapping of the foreign matter D. Even if the pressure-sensitive sensor 110 can be pressed, a pressing force exceeding a predetermined value cannot be obtained depending on the direction in which the external force acts, and pinching cannot be reliably detected. The above problem occurs remarkably as the size of the side visor increases.
[0004]
Therefore, if a conventional anti-pinch mechanism is used to detect a foreign object in a wide detection range with respect to the direction of the external force, the pressure sensor itself needs to be enlarged. However, when the pressure sensor is enlarged, not only is it difficult to place the pressure sensor on the window frame, but also the rigidity of the pressure sensor itself increases, and there is a problem that a low pinching load cannot be reliably detected.
[0005]
[Problems to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a vehicle door provided with a power window opening / closing device (power window mechanism) having a pinching prevention mechanism, wherein 1 is a drive motor for driving the window glass 2 for opening and closing the window opening 3a up and down. Is a window frame that partitions the window opening 3a. At the periphery of the window frame 3 on the vehicle interior side, pressure sensitive sensors 42 and 44 (sensing means) for detecting an external force are disposed from the front side 3b to the upper side 3c of the window frame 3, respectively. Further, a side visor 5 is attached to the outer periphery of the window frame 3 on the outside of the passenger compartment. Incidentally, the pressure-sensitive sensors 42 and 44 are provided on the vehicle interior side because they are likely to deteriorate when provided on the vehicle exterior side.
[0017]
These pressure-sensitive sensors 42 and 44 have independent pressure-sensitive functions. That is, the detection levels of the pressure sensitive sensors 42 and 44 are set to be different from each other. When an external force of a predetermined value or more acts on at least one of the pressure sensitive sensors 42 and 44, a pressure sensitive signal 42a (44a) is generated. When the pressure-sensitive signal 42a (44a) is generated, the pressure-sensitive signal 42a (44a) is input to the control device 6, and the control device 6 receives the pressure-sensitive signal 42a (44a) and the drive device 1 Then, an inversion signal 6a is issued so as to invert (lower) the window glass 2. With the configuration described above, the closing movement stopping means for stopping the movement of the window glass 2 in the closing direction is configured.
[0018]
Further, as shown in FIG. 2, the window frame 3 is provided with a weather strip 7 provided on the vehicle interior side along the window frame 3 to seal a gap between the window glass 2 and the window frame 3. . And the pressure sensitive sensors 42 and 44 are integrally arrange | positioned so that it may mutually become parallel inside the elastic foam 8 which consists of an insulating member fixed to this weather strip 7. FIG.
[0019]
Specifically, the pressure sensitive sensors 42 and 44 are arranged in parallel along the window frame 3 with a predetermined interval in a direction intersecting the opening / closing direction of the window glass 2. The relationship between the distance L1 from the window glass 2 to the pressure-sensitive sensor 42 extending vertically and the distance L2 from the window glass 2 to the pressure-sensitive sensor 44 extending vertically is L1 <L2. 7a and 7b are metal cores for increasing the mechanical strength of the weather strip 7, and these cores are usually bent along the cross-sectional shape of the window frame 3.
[0020]
Hereinafter, the structure of the pressure sensitive sensors 42 and 44 will be described.
In the present embodiment, although the pressure sensitive sensors 42 and 44 have different detection levels, since both have the same structure, only the structure of the pressure sensitive sensor 42 will be described.
[0021]
As shown in FIG. 3, the pressure-sensitive sensor 42 extends in the longitudinal direction of the tube 41 on the inner peripheral wall of the long tube 41 made of a flexible insulating material and has a predetermined distance within the tube 41. Thus, two strip-like electrodes 43 and 45 made of a conductive rubber material facing each other are provided.
[0022]
A gap 46 is formed between the opposing surfaces 43a and 45a of the band plate electrodes 43 and 45 to form an insulating portion. A predetermined voltage is applied between the band plate electrodes 43 and 45, and the tube 41 is deformed when an external force exceeding a predetermined value is applied, and the opposing surfaces 43 a and 45 a come into contact with the deformation of the tube 41. When the opposing surfaces 43a and 45a come into contact with each other, they are electrically connected to each other and the pressure sensitive signal 42a is generated. Similarly, the pressure-sensitive signal 44a is generated when a predetermined or higher external force acts on the pressure-sensitive sensor 44.
[0023]
Note that the tubes 41 of the pressure sensors 42 and 44 may be eliminated, and the two strip plate electrodes 43 and 45 may be integrally disposed on the weather strip 7.
[0024]
Next, features of the present embodiment will be described.
According to this embodiment, two pressure sensitive sensors 42 and 44 are arranged in parallel along the window frame 3 in the weather strip 7. When at least one of the pressure sensitive sensors 42 and 44 senses an external force, a pressure sensitive signal is issued to the control device 6 so as to stop the movement of the window glass 2 in the closing direction.
[0025]
That is, as shown in FIG. 4, when the foreign matter A is sandwiched between the window glass 2 and the tip 5a of the side visor 5 and the weather strip 7 (elastic foam 8) during the closing operation of the window glass 2, The pressure sensor 44 detects an external force, and the window glass 2 is opened by the above-described closing movement stopping means.
[0026]
Further, when the foreign matter B is sandwiched between the window glass 2 and the weather strip 7 (elastic foam 8) during the closing operation of the window glass 2, the pressure-sensitive tube sensor 42 detects the external force and moves it closed. The window glass 2 is opened by the stopping means.
[0027]
Further, when foreign matter C is sandwiched between the window glass 2 and the weather strip 7, the pressure sensitive tube sensors 42 and 44 both detect external force and the window glass 2 is opened by the closing movement stopping means. .
[0028]
That is, by providing the two pressure sensitive sensors 42 and 44 along the window frame 3, the detection range of the foreign object is widened, and therefore the side visor 5 is attached to the window frame 3 outside the vehicle compartment. In addition, the pinching can be reliably detected regardless of the direction of the external force.
[0029]
Further, since the two pressure sensitive sensors 42 and 44 are arranged in the weather strip 7 as in the present embodiment, the distance between the pressure sensitive sensors 42 and 44 can be kept at a predetermined distance, and Easy to install.
[0030]
Furthermore, as shown in FIG. 5, when the pressure sensors 42, 44 are directly attached to the window frame 3 without using a weather strip, the pressure sensors 42, 44 are made of a flexible insulating member or the like (elastic rubber 9). 44 can be attached to the window frame 3 side easily by holding 44 integrally and fixing a part of the elastic rubber 9 to the metal core member 7c with the screw 10 or the like. Moreover, you may fix the elastic rubber 9 to the core material 7c with an adhesive material. Further, as shown in FIG. 6, the pressure-sensitive sensors 42 and 44 may be integrally held by a tube 48 and stored in the elastic rubber 11.

On the other hand, in the weather strip 7 on the vehicle interior side of the vehicle door, two pressure sensitive sensors 42 and 44 are laid in parallel to each other. The pressure sensor signals 42 a and 44 a from these pressure sensors 42 and 44 are input to the OR gate 50. An output signal from the OR gate 50 is input to the AND gate 51.
[0033]
Further, the window closing signal 61 a is input to the AND gate 51. The window closing signal 61a is generated during normal rotation of the motor (window glass closing direction), for example, depending on the polarity of the motor terminal. The output of the AND gate 51 is input to the control circuit 60b that constitutes the control device 6. The control circuit 60b activates the motor reversing circuit 60a in response to a command from the operation switch 80, and the motor reversing circuit 60a switches the polarity of the DC voltage from the battery 70 appropriately and applies it to the driving motor 1 to correct the motor 1. Reverse.
[0034]
