Abstract
Description
本発明は、トラック、乗用車、バス等のフロントピラー及びドアフレームからなるフロントコーナ部材やフロントピラーからなるフロントコーナ部材の構造に関するものである。 The present invention relates to a structure of a front corner member composed of a front pillar and a door frame of a truck, a passenger car, a bus and the like, and a front corner member composed of a front pillar.
小型トラックの関与した死亡事故は、小型トラックが交差点で対向車線を横切って曲がるとき、即ち交差点右折時における横断中の歩行者との衝突事故が最も多い。具体的には、２０００年の小型トラックの関与した死亡事故の統計データによれば、事故の相手としては、図９に示すように、歩行者が４６５人中９８人と最も多く、自転車運転者が４６５人中９６人と２番目に多かった。また相手が歩行者及び自転車運転者である場合、歩行者及び自転車運転者の行動としては、図１０に示すように、交差点横断中が１９４人中９９人（歩行者：４５人、自転車運転者：５４人）と最も多かった。更に相手が交差点横断中の歩行者である場合、小型トラックの行動としては、図１１に示すように、交差点右折時が４５人中２５人と最も多かった。このように小型トラックの交差点右折時における横断中の歩行者との衝突事故が多い一因としては、図１２に示すように、小型トラック１が右折しようとして交差点５に進入するとき、小型トラック１の運転者２が直進する対向車に気を取られて右折側の横断歩道３を横断する歩行者８に気付かず、直進する対向車がなくなって小型トラック１が右折し始めてから右折側の横断歩道３上を見るため、歩行者８が運転席側のフロントコーナ部材６に隠れて視認し難いことが挙げられる。特に車両１の剛性を高めるためにフロントコーナ部材６を太くした車両１では、歩行者８が運転席側のフロントコーナ部材６に隠れる割合が多い。 The most common fatal accidents involving small trucks are collisions with pedestrians crossing when the small truck turns across the opposite lane at the intersection, that is, when turning right at the intersection. Specifically, according to the statistics of death accidents involving small trucks in 2000, as shown in Fig. 9, the number of pedestrians was the largest, 98 out of 465, and bicycle drivers. There were 96 out of 465 people, the second most common. Further, when the other party is a pedestrian and a bicycle driver, as shown in FIG. 10, the behavior of the pedestrian and the bicycle driver is 99 out of 194 people crossing the intersection (45 pedestrians, bicycle drivers). : 54 people). Furthermore, when the other party is a pedestrian crossing the intersection, as shown in FIG. 11, the most frequent behavior of the small truck was 25 out of 45 people when turning right at the intersection. As described above, as shown in FIG. 12, when the small truck 1 enters the intersection 5 in order to make a right turn, the small truck 1 may cause a collision accident with a crossing pedestrian during the right turn of the small truck. The driver 2 is distracted by the oncoming vehicle that goes straight and does not notice the pedestrian 8 who crosses the pedestrian crossing 3 on the right turn side. After the oncoming vehicle goes straight and the small truck 1 starts to turn right, the right turn side crossing Since the pedestrian 8 is seen on the sidewalk 3, it is difficult for the pedestrian 8 to be hidden behind the front corner member 6 on the driver's seat side. In particular, in the vehicle 1 in which the front corner member 6 is thickened in order to increase the rigidity of the vehicle 1, the pedestrian 8 is often hidden in the front corner member 6 on the driver's seat side.
この点を解消するために、窓などが形成されたフロントピラーが開示されている（例えば、特許文献１及び２参照。）。特許文献１には、金属材料で形成した外枠部と、合成樹脂等透明材料で形成した中央窓部とからなる車両のフロントピラーが記載されている。この車両のフロントピラーでは、運転席からの死角を減少でき、運転室の視界拡大を図ることができるので、安全性を向上できるようになっている。
また上記特許文献２には、自動車のフロントピラーに窓が設けられ、この窓に透明板が固定された自動車が提案されている。このフロントピラーに窓を付けた自動車では、右折又は左折時に、フロントピラーの窓を透して歩行者をいち早く確認でき、交通事故を未然に防止できるようになっている。
Patent Document 2 proposes an automobile in which a window is provided in a front pillar of an automobile and a transparent plate is fixed to the window. In a car with a window on the front pillar, when turning right or left, a pedestrian can be quickly confirmed through the window of the front pillar so that a traffic accident can be prevented.
しかし、上記従来の特許文献１に示された車両のフロントピラーや特許文献２に示されたフロントピラーに窓を付けた自動車では、フロントピラーの窓部の曇りに対する配慮や、部品点数及び製造工数の増大など、克服しなければならない技術的課題が多いため、実現が難しかった。
本発明の目的は、フロントピラーへの窓部の形成という複雑な構造を採らずに、運転席からのフロントコーナ部材の向こう側の視認性を向上できるとともに、運転者の疲労を軽減できる、車両の前部構造を提供することにある。
However, in the conventional vehicle front pillar shown in Patent Document 1 and the automobile provided with a window on the front pillar shown in Patent Document 2, consideration is given to fogging of the window portion of the front pillar, the number of parts, and the number of manufacturing steps. Because there are many technical issues that must be overcome, such as an increase in
An object of the present invention is to improve the visibility of the front corner member from the driver's seat beyond the front corner member without taking the complicated structure of forming the window portion on the front pillar, and reduce the driver's fatigue. Is to provide a front structure.
請求項１に係る発明は、図１〜図３及び図５に示すように、ウインドシールドガラス１３の側縁とサイドガラス１４ｄの前縁との間に、ウインドシールドガラス１３の側縁及びサイドガラス１４ｄの前縁に沿って延びるフロントコーナ部材１６が設けられた車両の前部構造の改良である。
その特徴ある構成は、車両１０の運転席に着席しかつ瞳孔間隔が６６ｍｍである運転者１２がフロントコーナ部材１６の方向を両眼１２ａ,１２ｂで見たときであって、フロントコーナ部材１６に向けられた運転者１２の視線上に運転者１２の瞳孔１２ｃ,１２ｄから少なくとも５ｍ離れた車外の対象物１８が存在し、車両１０の運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅及び対象物１８のの幅をそれぞれＭ及びＡとし、このＡが１５５ｍｍであるとき、フロントコーナ部材１６が存在しても、対象物１８のＡ／３以上の部分を運転者１２が視認できるＭをフロントコーナ部材１６が有するところにある。
As shown in FIGS. 1 to 3 and 5, the invention according to claim 1 includes the side edge of the windshield glass 13 and the side glass 14 d between the side edge of the windshield glass 13 and the front edge of the side glass 14 d. This is an improvement of the front structure of the vehicle provided with a front corner member 16 extending along the front edge.
The characteristic configuration is when the driver 12 sitting in the driver's seat of the vehicle 10 and having a pupil interval of 66 mm looks at the direction of the front corner member 16 with both eyes 12a and 12b. The front corner when the driver 12 seated in the driver's seat of the vehicle 10 sees the object 18 outside the vehicle at least 5 m away from the pupils 12c, 12d of the driver 12 on the line of sight of the driver 12 directed. When the width of the member 16 and the width of the object 18 are M and A, respectively, and A is 155 mm, even if the front corner member 16 is present, a portion equal to or greater than A / 3 of the object 18 is provided to the driver 12. Is located where the front corner member 16 has M.
この請求項１に記載された車両の前部構造では、例えば対向車線のある最も狭い道路１９の交差点２２、即ち対面通行の片側一車線道路１９の交差点２２で右折するためにこの交差点２２で車両１０を一時停止させた状態で、この車両１０の運転者１２が右斜め前方の車外に対象物１８が存在するか否かを確認するときであって、この車両１０の運転者１２を１８才以上の日本人男性のうち平均的な瞳孔間隔６６ｍｍを有する日本人男性（以下、ＪＭ５０の日本人男性という）とするとき、ＪＭ５０の日本人男性の運転者１２、即ち１８才以上の全日本人男性のうちの半数の運転者１２は、幅Ｍのフロントコーナ部材１６が存在しても、対象物１８のＡ／３以上の部分を視認できる。換言すれば、ＪＭ５０の日本人男性の運転者１２は比較的遠い上記歩行者１８に両眼１２ａ，１２ｂの焦点を合わせており、両眼１２ａ，１２ｂの視差により運転者１２の近くに存在するフロントコーナ部材１６の幅Ｍが比較的狭く、両眼死角領域から歩行者１８のＡ／３以上の部分がはみ出すので、運転者１２はこのはみ出し部分を左眼１２ａ又は右眼１２ｂのいずれか一方又は双方で視認できる。また１８才以上の日本人の瞳孔間隔には大きな差がないため、ＪＭ５０の日本人男性の運転者が対象物のＡ／３以上の部分を見ることができれば、１８才以上の大部分の日本人の運転者が対象物を実用上確実に視認できる。 In the front structure of the vehicle according to claim 1, for example, the vehicle at this intersection 22 to turn right at the intersection 22 of the narrowest road 19 with the opposite lane, that is, the intersection 22 of the one-sided one-lane road 19 with two-way traffic. 10 when the driver 12 of the vehicle 10 checks whether or not the object 18 is present outside the vehicle diagonally to the right, and the driver 12 of the vehicle 10 is 18 years old. JM50 Japanese male driver 12, that is, all Japanese males 18 years of age or older when the Japanese male has an average pupil spacing of 66 mm (hereinafter referred to as JM50 Japanese male). Half of the drivers 12 can visually recognize the portion of the object 18 that is not less than A / 3 even if the front corner member 16 having the width M exists. In other words, the Japanese male driver 12 of JM50 focuses the eyes 12a and 12b on the pedestrian 18 which is relatively far away, and is present near the driver 12 due to the parallax between the eyes 12a and 12b. Since the width M of the front corner member 16 is relatively narrow and a portion of the pedestrian 18 exceeding A / 3 protrudes from the binocular blind spot region, the driver 12 can detect either the left eye 12a or the right eye 12b. Or it can be visually recognized by both. In addition, there is no big difference in pupil spacing between Japanese over 18 years old, so if a Japanese male driver of JM50 can see A / 3 or above part of the object, most Japanese over 18 years old A human driver can surely see the object practically.
ここで、車両１０の運転者１２の瞳孔間隔を６６ｍｍに規定したのは、無作為で選んだ１００人の自動車の普通免許又は大型免許等を取得可能な１８才以上の日本人男性を身長の小さい順に１列に並ばせたとき、前から５０番目の日本人男性の両眼の瞳孔間隔Ｄが６６ｍｍであり、１８才以上の日本人男性のうち平均的な瞳孔間隔を有する日本人男性（ＪＭ５０の日本人男性）を基準にしたからである。
また、対象物１８の幅Ａを１５５ｍｍと規定したのは、交差点等の横断歩道を単独で渡る者のうち最も小さい者を日本人の小学１年生、即ち日本人の７才児と考え、この日本人の７才児のうち最も幅が狭い状態が運転者の視線方向に対して横を向いたときの胸厚であり、この日本人の７才児の胸幅の平均値が１５５ｍｍだからである。
また、運転者１２の瞳孔１２ｃ，１２ｄから対象物１８までの距離を少なくとも５ｍと規定したのは、対向車線のある最も狭い道路の交差点２２、即ち対面通行の片側一車線道路の交差点２２で車両１０が走行道路１９から交差道路２１に右折するときに、この車両１０の運転者１２の瞳孔１２ｃ，１２ｄから交差道路２１の右側の横断歩道２１ａを横断している歩行者等の対象物１８までの距離が約５ｍだからである。
更に、運転者１２の視認できる対象物１８の範囲をＡ／３以上の部分としたのは、評価試験を行った結果、フロントコーナ部材１６が存在しても、運転者１２が対象物１８を認識できる幅の最小値がＡ／３であったからである。

以上述べたように、本発明によれば、車両の運転席に着席したＪＭ５０の日本人男性の運転者がフロントコーナ部材の方向を両眼で見たときに、フロントコーナ部材が存在しても、対象物のＡ／３以上の部分を視認できる幅Ｍをフロントコーナ部材が有するので、１８才以上の全日本人男性の半数の運転者は、フロントコーナ部材の向こう側を視認するために上体を左右に動かす必要がなく、首のみを動かしてフロントコーナ部材の方向を正視するだけで、横断歩道等を単独で渡る最も小さい車外の対象物を確実に視認できる。また１８才以上の日本人の瞳孔間隔には大きな差がないため、ＪＭ５０の日本人男性の運転者が対象物のＡ／３以上の部分視認できれば、１８才以上の大部分の日本人の運転者が対象物を実用上確実に視認できる。この結果、運転席からのフロントコーナ部材の向こう側の視認性を向上できるとともに、運転者の疲労を軽減できる。また車両の運転者が外国人であっても、この外国人の瞳孔間隔は日本人の運転者の瞳孔間隔とさほど変わらず、対象物が外国人の７才児であっても、この外国人の７才児の胸幅は日本人の７才児の胸幅と殆ど変わらないため、本発明は日本国内だけでなく外国においても適用でき、上記と同等の効果が得られる。
また車両の運転席に着席した運転者が見たときのフロントコーナ部材の幅が５８ｍｍを越えかつ７２ｍｍ以下であれば、通常の車両において運転者がフロントコーナ部材を見たときに、運転者の瞳孔からフロントコーナ部材までの距離が約７００ｍｍであり、この場合の対象物のＡ／３以上の部分の視認性を確保できるフロントコーナ部材の実際上の幅となり、上記と同様の効果が得られる。
またＪＭ５０の日本人男性の運転者が車外の対象物を見たときに、フロントコーナ部材が存在しても、対象物のＡ／２以上の部分を視認できる幅Ｍをフロントコーナ部材が有すれば、１８才以上の全日本人男性の半数の運転者が上記対象物のＡ／２以上と上記Ａ／３以上の場合より多い部分を視認できる、即ち大部分の運転者がＡ／３以上の部分を視認できる。この結果、運転席からのフロントコーナ部材の向こう側の視認性を大幅に向上できるとともに、運転者の疲労をより軽減できる。
また車両の運転席に着席した運転者が見たときのフロントコーナ部材の幅が５８ｍｍを越えかつ６８ｍｍ以下であれば、通常の車両において運転者がフロントコーナ部材を見たときに、運転者の瞳孔からフロントコーナ部材までの距離が約７００ｍｍであり、この場合の対象物のＡ／２以上の部分の視認性を確保できるフロントコーナ部材の実際上の幅となり、上記と同様の効果が得られる。
As described above, according to the present invention, even if the front corner member is present when the driver of a Japanese male JM50 seated in the driver's seat of the vehicle sees the direction of the front corner member with both eyes. Because the front corner member has a width M that allows the portion of the object to be recognized by A / 3 or more, half of all Japanese male drivers 18 years of age and older are able to see the other side of the front corner member. There is no need to move left and right, and by moving only the neck and looking straight at the direction of the front corner member, the smallest object outside the vehicle that crosses a pedestrian crossing or the like can be reliably recognized. Also, there is no significant difference in the pupil spacing between Japanese over 18 years old, so if a Japanese male driver of JM50 can see a part of the object over A / 3, most Japanese over 18 years old will drive. A person can surely visually recognize an object in practice. As a result, the visibility beyond the front corner member from the driver's seat can be improved, and the driver's fatigue can be reduced. Even if the driver of the vehicle is a foreigner, this foreigner's pupil spacing is not much different from that of a Japanese driver, even if the object is a foreign 7-year-old child. Since the breast width of a 7-year-old child is almost the same as that of a Japanese 7-year-old child, the present invention can be applied not only in Japan but also abroad, and the same effect as described above can be obtained.
Further, if the width of the front corner member when viewed by the driver seated in the driver's seat of the vehicle is more than 58 mm and not more than 72 mm, when the driver views the front corner member in a normal vehicle, The distance from the pupil to the front corner member is about 700 mm, and this is the actual width of the front corner member that can ensure the visibility of the A / 3 portion or more of the object in this case, and the same effect as described above can be obtained. .
In addition, when a Japanese male driver of JM50 looks at an object outside the vehicle, the front corner member has a width M that allows the portion of the object to be viewed at least A / 2 even if the front corner member exists. For example, half of all Japanese male drivers 18 years or older can see more than A / 2 of the object and more than A / 3, that is, most drivers are A / 3 or more. You can see the part. As a result, the visibility beyond the front corner member from the driver's seat can be greatly improved, and the driver's fatigue can be further reduced.
Further, if the width of the front corner member when viewed by the driver seated in the driver's seat of the vehicle exceeds 58 mm and is 68 mm or less, when the driver views the front corner member in a normal vehicle, The distance from the pupil to the front corner member is about 700 mm, and this is the actual width of the front corner member that can ensure the visibility of the A / 2 or more portion of the object in this case, and the same effect as described above can be obtained. .
また車両の運転席に着席したＪＦ５の日本人女性の運転者がフロントコーナ部材の方向を両眼で見たときに、フロントコーナ部材が存在しても、対象物のＡ／３以上の部分を視認できる幅Ｍをフロントコーナ部材が有すれば、１８才以上の大部分の日本人の運転者は、フロントコーナ部材の向こう側を視認するために上体を左右に動かす必要がなく、首のみを動かしてフロントコーナ部材の方向を正視するだけで、車外の対象物を上記より確実に視認できる。また１８才以上の日本人の瞳孔間隔には大きな差がないため、ＪＦ５の日本人女性の運転者が対象物のＡ／３以上の部分を視認できれば、１８才以上の殆ど全ての日本人の運転者が横断歩道等を単独で渡る最も小さい車外の対象物を実用上確実に視認できる。この結果、運転席からのフロントコーナ部材の向こう側の視認性を更に向上できるとともに、運転者の疲労を更に軽減できる。
また車両の運転席に着席した運転者が見たときのフロントコーナ部材の幅が５８ｍｍを越えかつ６５ｍｍ以下であれば、通常の車両において運転者がフロントコーナ部材を見たときに、運転者の瞳孔からフロントコーナ部材までの距離が約７００ｍｍであり、この場合の対象物のＡ／３以上の部分の視認性を確保できるフロントコーナ部材の実際上の幅となり、上記と同様の効果が得られる。
またＪＦ５の日本人女性の運転者が車外の対象物を見たときに、フロントコーナ部材が存在しても、対象物のＡ／２以上の部分を視認できる幅Ｍをフロントコーナ部材が有すれば、１８才以上の大部分の日本人の運転者が上記対象物のＡ／２以上と上記Ａ／３以上の場合より多い部分を視認できる。この結果、運転席からのフロントコーナ部材の向こう側の視認性は極めて良好になるとともに、運転者の疲労は極めて少なくなる。
更に車両の運転席に着席した運転者が見たときのフロントコーナ部材の幅が５８ｍｍを越えかつ６１ｍｍ以下であれば、通常の車両において運転者がフロントコーナ部材を見たときに、運転者の瞳孔からフロントコーナ部材までの距離が約７００ｍｍであり、この場合の対象物のＡ／２以上の部分の視認性を確保できるフロントコーナ部材の実際上の幅となり、上記と同様の効果が得られる。
Also, when a JF5 Japanese female driver sitting in the driver's seat looks at the direction of the front corner member with both eyes, even if the front corner member is present, the A / 3 or more portion of the object If the front corner member has a visible width M, most Japanese drivers over the age of 18 do not need to move the upper body to the left or right to see the other side of the front corner member, only the neck The object outside the vehicle can be seen more reliably than above just by moving the front-viewing the direction of the front corner member. Also, there is no big difference in the pupil spacing between Japanese over 18 years old, so if a Japanese female driver of JF5 can see the A / 3 or higher part of the object, almost all Japanese over 18 years old A driver can visually recognize the smallest outside object crossing a pedestrian crossing etc. practically and reliably. As a result, the visibility beyond the front corner member from the driver's seat can be further improved, and the driver's fatigue can be further reduced.
Further, if the width of the front corner member when viewed by the driver seated in the driver's seat of the vehicle exceeds 58 mm and is 65 mm or less, when the driver views the front corner member in a normal vehicle, the driver's The distance from the pupil to the front corner member is about 700 mm, and this is the actual width of the front corner member that can ensure the visibility of the A / 3 portion or more of the object in this case, and the same effect as described above can be obtained. .
In addition, when a Japanese female driver of JF5 looks at an object outside the vehicle, the front corner member has a width M that allows a portion larger than A / 2 of the object to be visually recognized even if the front corner member exists. For example, most Japanese drivers over the age of 18 can see more parts of the object than A / 2 and more than A / 3 and above. As a result, the visibility of the other side of the front corner member from the driver's seat becomes extremely good, and the driver's fatigue is extremely reduced.
Further, if the width of the front corner member when viewed by the driver seated in the driver's seat of the vehicle is more than 58 mm and not more than 61 mm, when the driver views the front corner member in a normal vehicle, the driver's The distance from the pupil to the front corner member is about 700 mm, and this is the actual width of the front corner member that can ensure the visibility of the A / 2 or more portion of the object in this case, and the same effect as described above can be obtained. .

The side door 14 closes the door main body 14a, the door frame 14c provided on the upper surface of the door main body 14a and formed in a substantially inverted U shape to form the door window 14b, and the door window 14b so as to be openable. And a transparent side glass 14d. A front corner member 16 extending along the right edge of the windshield glass 13 and the front edge of the side glass 14d is provided between the right edge of the windshield glass 13 and the front edge of the side glass 14d (FIGS. 1 and 3). . In this embodiment, the front corner member 16 includes a front pillar 17, a door frame 14c, a glass frame 14e, a glass run 14f, and a weather strip 37. The door frame 14c is formed by joining the door inner panel 14g and the door outer panel 14h (FIG. 3). Further, the glass frame 14e is inserted into the door frame 14c, and the glass run 14f is attached to the glass frame 14e to hold and guide the side glass 14d.
この実施の形態の特徴ある構成は、トラック１０の運転席に着席しかつ瞳孔間隔が６６ｍｍであるＪＭ５０の日本人男性の運転者１２がフロントコーナ部材１６の方向を両眼１２ａ，１２ｂで見たときであって、フロントコーナ部材１６に向けられた運転者１２の視線上に運転者１２の瞳孔１２ｃ,１２ｄから少なくとも５ｍ離れた車外の対象物１８（図１及び図２）が存在し、車両１０の運転席に着席した運転者１２が見たときのフロントコーナ部材１６及び対象物１８の幅をそれぞれＭ（図３）及びＡ（図１）とし、このＡが１５５ｍｍであるとき、フロントコーナ部材１６が存在しても、対象物１８のＡ／３以上の部分を運転者１２が視認できるＭをフロントコーナ部材１６が有するところにある。車外の対象物１８は、この実施の形態では、トラック１０の走行する走行道路１９と交差する交差道路２１のうち両道路１９，２１の交差点２２のトラック１０の運転者から見て右側の横断歩道２１ａを単独で渡る歩行者のうち最も小さい者、即ち日本人の７才児（小学１年生）である（図１及び図２）。ここで、歩行者１８の幅を１５５ｍｍと規定したのは、上記［発明が解決しようとする手段］の請求項１に記載した理由に基づく。また車両１０の運転者１２の瞳孔間隔を６６ｍｍに規定したのは、上記［発明が解決しようとする手段］の請求項１に記載した理由に基づく。更に運転者１２の瞳孔１２ｃ，１２ｄから歩行者１８までの距離を少なくとも５ｍと規定したのは、上記［発明が解決しようとする手段］の請求項１に記載した理由に基づく。 The characteristic configuration of this embodiment is that a Japanese male driver 12 of JM50 who is seated in the driver's seat of the truck 10 and whose pupil distance is 66 mm looks at the direction of the front corner member 16 with both eyes 12a and 12b. There is an object 18 (FIGS. 1 and 2) outside the vehicle that is at least 5 m away from the pupils 12c and 12d of the driver 12 on the line of sight of the driver 12 directed to the front corner member 16, and the vehicle The width of the front corner member 16 and the object 18 when the driver 12 seated in the 10 driver's seat is viewed as M (FIG. 3) and A (FIG. 1), respectively, and when this A is 155 mm, the front corner Even if the member 16 exists, the front corner member 16 has the M that allows the driver 12 to visually recognize the portion of the object 18 that is A / 3 or more. In this embodiment, the object 18 outside the vehicle is a pedestrian crossing on the right side when viewed from the driver of the truck 10 at the intersection 22 of both roads 19 and 21 of the intersection road 21 intersecting the traveling road 19 on which the truck 10 travels. The smallest person among pedestrians crossing 21a, that is, a 7-year-old Japanese (first grader) (FIGS. 1 and 2). Here, the reason why the width of the pedestrian 18 is defined as 155 mm is based on the reason described in claim 1 of the above [Means to be Solved by the Invention]. The reason why the pupil distance of the driver 12 of the vehicle 10 is set to 66 mm is based on the reason described in claim 1 of the above [Means to be Solved by the Invention]. The reason why the distance from the pupils 12c and 12d of the driver 12 to the pedestrian 18 is defined as at least 5 m is based on the reason described in claim 1 of the above-mentioned [Means to be Solved by the Invention].
一方、トラック１０の運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅Ｍは、この実施の形態では、７２ｍｍ以下であり、好ましくは５８ｍｍを越えかつ７２ｍｍ以下である。この運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅とは、運転者１２がフロントコーナ部材１６を正視し（図１）、運転者１２の両眼１２ａ，１２ｂの瞳孔１２ｃ，１２ｄを結ぶ線分を含む略水平面で上記フロントコーナ部材１６を切断し（図３）、更に運転者１２の両眼１２ａ，１２ｂの瞳孔１２ｃ，１２ｄを結ぶ線分の中点からこの線分に直交する垂線Ｓ（視線方向、図１）をフロントコーナ部材１６に向って略水平面内で引いたときに、この垂線に平行な２本の平行線Ｓ1及びＳ2（図３）でフロントコーナ部材１６を挟んだこれら２本の平行線の間隔Ｍ（図３）をいう。なお、運転者１２がフロントコーナ部材１６を正視するとしたけれども、図１では説明を分かり易くするため簡略的に右眼の瞳孔を基準に表現している。また図１において、両眼死角領域とは運転者１２の両眼１２ａ，１２ｂで視認できない領域をいい、左眼死角領域とは運転者１２の右眼１２ｂで視認できるけれども左眼１２ａで視認できない領域をいい、右眼死角領域とは運転者１２の左眼１２ａで視認できるけれども右眼１２ｂで視認できない領域をいう。なお、この実施の形態では、運転者の両眼の瞳孔を結ぶ線分を含む略水平面でフロントコーナ部材を切断したが、水平面又は傾斜面に拘らず運転者の両眼と歩行者を含む平面でフロントコーナ部材を切断してもよい。 On the other hand, the width M of the front corner member 16 when viewed by the driver 12 seated in the driver's seat of the truck 10 is 72 mm or less in this embodiment, preferably more than 58 mm and 72 mm or less. The width of the front corner member 16 as viewed by the driver 12 seated in the driver's seat means that the driver 12 views the front corner member 16 from the front (FIG. 1), and the pupils of both eyes 12a and 12b of the driver 12 The front corner member 16 is cut at a substantially horizontal plane including a line segment connecting 12c and 12d (FIG. 3), and this line is further drawn from the midpoint of the line segment connecting the pupils 12c and 12d of both eyes 12a and 12b of the driver 12. When a perpendicular S (line of sight, FIG. 1) perpendicular to the minute is drawn in a substantially horizontal plane toward the front corner member 16, two parallel lines S 1 and S 2 (FIG. 3) parallel to the perpendicular are drawn. The interval M (FIG. 3) between these two parallel lines sandwiching the front corner member 16 is referred to. Although it is assumed that the driver 12 views the front corner member 16 directly, in FIG. 1, the right eye pupil is simply expressed as a reference for easy understanding. In FIG. 1, the binocular blind spot area refers to an area that cannot be viewed with both eyes 12 a and 12 b of the driver 12, and the left-eye blind spot area can be viewed with the right eye 12 b of the driver 12 but cannot be viewed with the left eye 12 a. The right eye blind spot area means an area that can be visually recognized by the left eye 12a of the driver 12 but cannot be visually recognized by the right eye 12b. In this embodiment, the front corner member is cut in a substantially horizontal plane including a line segment connecting the pupils of both eyes of the driver, but the plane including the driver's eyes and the pedestrian regardless of the horizontal plane or the inclined plane. The front corner member may be cut by.
上記フロントコーナ部材１６の幅Ｍの最大値（７２ｍｍ）は、運転者１２の瞳孔１２ｃ，１２ｄから車外の歩行者１８までの距離をＬ1とし、運転者１２の瞳孔１２ｃ，１２ｄからフロントコーナ部材１８までの距離をＬ2とし、瞳孔間隔をＤとし、車外の歩行者１８の幅をＡとするとき、次の式（１）から求められる（図１、図３及び図５）。
Ｍ ＝ [〔(２／３)×Ａ−Ｄ〕／Ｌ1］×Ｌ2＋Ｄ ……（１）
上記式（１）に、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝６６ｍｍ、Ａ＝１５５ｍｍをそれぞれ代入すると、Ｍ＝７１．２３ｍｍとなり、小数点以下を切り上げてＭ＝７２ｍｍとなる。なお、運転者１２の瞳孔１２ｃ，１２ｄからフロントコーナ部材１６までの距離Ｌ2を７００ｍｍとしたのは、このＬ2が車種によって或いは運転席の前後方向への調整によって異なるため、その平均値を採ったものであり、積載量がほぼ２トンであるキャブオーバ型トラックにおける位置関係、即ち運転者１２の瞳孔１２ｃ，１２ｄからフロントコーナ部材１６までの距離Ｌ2が約７００ｍｍだからである。また、図１に示すように、運転者１２の両眼死角領域内にフロントコーナ部材１６が収まるように、フロントコーナ部材の幅Ｍと、運転者１２の瞳孔１２ｃ，１２ｄからフロントコーナ部材１８までの距離をＬ2とが設定される。また対象物１８のＡ／３以上の部分を運転者１２が視認できるＭをフロントコーナ部材１６が有することから、フロントコーナ部材１６により遮られて歩行者１８の２Ａ／３未満の部分、例えば歩行者１８の半分又は一部分を視認できなくてもよい。更に当然のことながら、歩行者１８の幅が１５５ｍｍを越える場合は、運転者１２は対象物１８のＡ／３を越える部分を視認できる。
Maximum width M of the front corner member 16 (72 mm), the pupil 12c of the driver 12, the distance from 12d to outside of the pedestrian 18 and L 1, pupil 12c of the driver 12, front corner member from 12d When the distance to 18 is L 2 , the pupil interval is D, and the width of the pedestrian 18 outside the vehicle is A, the following equation (1) is obtained (FIGS. 1, 3 and 5).
M = [[(2/3) × AD] / L 1 ] × L 2 + D (1)
Substituting L 1 = 5000 mm, L 2 = 700 mm, D = 66 mm, and A = 155 mm into the above equation (1) results in M = 71.23 mm, and rounds up the decimal part to M = 72 mm. The reason why the distance L 2 from the pupils 12c, 12d of the driver 12 to the front corner member 16 is set to 700 mm is that this L 2 varies depending on the vehicle type or the adjustment in the front-rear direction of the driver's seat. This is because the positional relationship in the cab-over type truck having a loading capacity of about 2 tons, that is, the distance L 2 from the pupils 12c and 12d of the driver 12 to the front corner member 16 is about 700 mm. Further, as shown in FIG. 1, the width M of the front corner member and the pupils 12c and 12d of the driver 12 to the front corner member 18 so that the front corner member 16 is within the blind spot area of the driver 12. set the distance of the L 2. Further, since the front corner member 16 has an M that allows the driver 12 to visually recognize the portion of the object 18 that is greater than or equal to A / 3, the front corner member 16 is blocked by the front corner member 16 and is less than 2A / 3, for example, walking. Half or part of the person 18 may not be visible. Furthermore, as a matter of course, when the width of the pedestrian 18 exceeds 155 mm, the driver 12 can visually recognize a portion of the object 18 exceeding A / 3.
フロントピラー１７は、ピラーインナパネル３１の両側縁とピラーアウタパネル３２の両側縁をそれぞれ接合することにより、例えばほぼ鉛直方向に延びる筒状に形成される（図３）。これによりフロントピラー１７の横断面は閉断面に形成される。ピラーインナパネル３１は、トラック１０の運転席に着席した運転者１２の視線方向に沿って設けられたピラーインナ本体３１ａと、ピラーインナ本体３１ａの前縁にこのピラーインナ本体３１ａと一体的に形成された第１フロントフランジ３１ｂと、ピラーインナ本体３１ａの後縁にこのピラーインナ本体３１ａと一体的に形成された第１リヤフランジ３１ｃとを有する。一方、ピラーアウタパネル３２は、ドアフレーム１４ｃの前面に略対向して設けられたピラーアウタ本体３２ａと、ピラーアウタ本体３２ａの前縁にこのピラーアウタ本体３２ａと一体的に形成された第２フロントフランジ３２ｂと、ピラーアウタ本体３２ａの後縁にこのピラーアウタ本体３２ａと一体的に形成された第２リヤフランジ３２ｃとを有する（図３）。また第１フロントフランジ３１ｂのピラー外面と第２フロントフランジ３２ｂのピラー内面とを接合することによりフロント重ね合せ部３３が形成され、第１リヤフランジ３１ｃのピラー内面と第２リヤフランジ３２ｃのピラー内面とを接合することによりリヤ重ね合せ部３４が形成される（図３）。更にフロント重ね合せ部３３とウインドシールドガラス１３の内面との隙間には接着剤３６が充填され、この接着剤３６によりウインドシールドガラス１３の側縁がフロントピラー１７に取付けられる。更にリヤ重ね合せ部３４には、フロントピラー１７とドアフレーム１４ｃとの隙間を塞ぐウエザストリップ３７が装着される。 The front pillar 17 is formed, for example, in a cylindrical shape extending in a substantially vertical direction by joining both side edges of the pillar inner panel 31 and both side edges of the pillar outer panel 32 (FIG. 3). Thereby, the cross section of the front pillar 17 is formed in a closed cross section. The pillar inner panel 31 includes a pillar inner body 31a provided along the line-of-sight direction of the driver 12 seated in the driver's seat of the truck 10, and a pillar inner body 31a formed integrally with the pillar inner body 31a at the front edge of the pillar inner body 31a. 1 front flange 31b and a first rear flange 31c formed integrally with the pillar inner body 31a at the rear edge of the pillar inner body 31a. On the other hand, the pillar outer panel 32 includes a pillar outer body 32a provided substantially opposite to the front surface of the door frame 14c, a second front flange 32b formed integrally with the pillar outer body 32a on the front edge of the pillar outer body 32a, A second outer flange 32c formed integrally with the pillar outer body 32a is provided at the rear edge of the pillar outer body 32a (FIG. 3). Also, the front overlapping portion 33 is formed by joining the pillar outer surface of the first front flange 31b and the pillar inner surface of the second front flange 32b, and the pillar inner surface of the first rear flange 31c and the pillar inner surface of the second rear flange 32c. Are joined together to form the rear overlap portion 34 (FIG. 3). Further, an adhesive 36 is filled in a gap between the front overlapping portion 33 and the inner surface of the windshield glass 13, and the side edge of the windshield glass 13 is attached to the front pillar 17 by the adhesive 36. Furthermore, a weather strip 37 that closes the gap between the front pillar 17 and the door frame 14c is attached to the rear overlapping portion 34.
このように構成されたトラック１０の動作を説明する。
図２に示すように、トラック１０が対面通行の片側一車線道路を走行し、交差点２２で右折するとき、走行道路１９の対向車線を直進する対向車が通り過ぎるまで交差点２２で停止して待つ。対向車が通り過ぎた後に、トラック１０の走行道路１９に交差する交差道路２１の右側の横断歩道２１ａ上を見て歩行者１８が横断しているか否かを確認する。このとき運転者１２をＪＭ５０の日本人男性とし、この運転者１２の瞳孔１２ｃ，１２ｄから交差道路２１の右斜め前方の車外の歩行者１８までの距離Ｌ1を５ｍとし、その歩行者１８の幅Ａを日本人の７才児の胸幅Ａの平均値を１５５ｍｍとすると、ＪＭ５０の日本人男性の運転者１２、即ち１８才以上の全日本人男性のうちの半数の運転者１２は、フロントコーナ部材１６が存在しても、歩行者１８のＡ／３以上の部分を視認できる（図１）。具体的には、歩行者１８が運転者１２の両眼死角領域から右眼死角領域にはみ出しているため、左眼１２ａで歩行者１８のＡ／３以上の部分を視認できる。歩行者１８のＡ／３以上の部分を視認できれば、フロントコーナ部材１８の向こう側に歩行者１８が存在することを認識できることは実験で確認した。また１８才以上の日本人の瞳孔間隔には大きな差がないため、ＪＭ５０の日本人男性の運転者１２が歩行者１８のＡ／３以上の部分を視認できれば、１８才以上の大部分の日本人の運転者１２が歩行者１８を確実に視認できる。
The operation of the track 10 thus configured will be described.
As shown in FIG. 2, when the truck 10 travels on a one-lane road with two-way traffic and makes a right turn at an intersection 22, the truck 10 stops at the intersection 22 and waits until an oncoming vehicle passing straight on the opposite lane of the traveling road 19 passes. After the oncoming vehicle passes, it is confirmed whether or not the pedestrian 18 is crossing by looking on the pedestrian crossing 21a on the right side of the cross road 21 that intersects the traveling road 19 of the truck 10. At this time, the driver 12 is a Japanese male of JM50, and the distance L 1 from the pupils 12c and 12d of the driver 12 to the pedestrian 18 outside the vehicle diagonally to the right of the cross road 21 is 5 m. If width A is the average value of breast width A of a 7-year-old Japanese 155 mm, JM50 Japanese male drivers 12, that is, half of all Japanese males over 18 years old, Even if the corner member 16 exists, a portion of the pedestrian 18 of A / 3 or more can be visually recognized (FIG. 1). Specifically, since the pedestrian 18 protrudes from the binocular blind spot area of the driver 12 to the right blind spot area, the left eye 12a can visually recognize a portion of the pedestrian 18 that is A / 3 or more. It was confirmed by an experiment that if a portion of A / 3 or more of the pedestrian 18 can be visually recognized, it can be recognized that the pedestrian 18 exists beyond the front corner member 18. Also, there is no significant difference in the pupil spacing between Japanese over 18 years old, so if Japanese male driver 12 at JM50 can see the A / 3 or higher part of pedestrian 18, most Japanese over 18 years old. The human driver 12 can reliably see the pedestrian 18.
一方、図６に示すように、車高の高いボンネット型のＲＶ（レジャービークル）車では、特別のミラー４１が左側フロントフェンダ１０ａの前部上面に取付けられたものが知られている（例えば、特開平８−２１６７８８号参照）。この特別のミラー４１は『直前直左用ミラー』と呼ばれ、ＲＶ車等の前方直下から側方直下にかけて運転者１２の死角を視認するためのものである。この特別のミラー４１の視界を評価する際に、対象物として、日本人の６才児の肩幅を直径とし身長を高さとする円柱体、即ち直径×高さが３００ｍｍ×１ｍである円柱体２８（図１）で評価される。この円柱体２８を歩行者とし、運転者１２の瞳孔間隔Ｄを、上記［発明が解決しようとする手段］の請求項５に記載したＪＦ５の日本人女性の瞳孔間隔５８ｍｍとし、上記式（１）中の『２／３』を『ｘ』とする。即ち、上記式（１）に、Ｍ＝７２ｍｍ、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝５８ｍｍ、Ａ＝３００ｍｍをそれぞれ代入してｘを求めると、ｘ＝０．５２７となる。この結果、歩行者２８の視認できる部分は（１−０．５２７）×３００＝１４２ｍｍとなり、ＪＦ５の日本人女性の運転者１２、即ち殆ど全ての日本人の運転者が歩行者２８の約１／２（４７．３％）の部分を視認できる。この結果、フロントコーナ部材１６の幅Ｍが７２ｍｍであれば、歩行者１０の幅（胸幅）が１５５ｍｍであるときＪＭ５０の日本人男性の運転者が歩行者のＡ／３の部分を視認でき、歩行者の直径（肩幅）が３００ｍｍであるとき瞳孔間隔の狭いＪＦ５の日本人女性の運転者でも歩行者の約Ａ／２の部分を視認できる。従って、トラック１０の運転者１２はフロントコーナ部材１６の向こう側を視認するために上体を左右に動かす必要がなく、首のみを動かしてフロントコーナ部材１６の方向を正視するだけで横断歩道２１ａ上の歩行者１８，２８を確実に視認できるとともに、運転者１２の疲労を軽減できる。また運転者１２は横断歩道２１ａ上に歩行者１８がいないと判断すると、速やかに交差点２２を右折する。更に運転者１２が見たときのフロントコーナ部材１６の幅を７２ｍｍ以下、好ましくは５８ｍｍを越えかつ７２ｍｍ以下と狭くすることにより、ウインドシールドガラス１３の両側部が拡大される。この拡大されたウインドシールドガラス１３の両側部は、ワイパにより払拭できるとともに、デフロスタにより曇りを確実に除去できる。この結果、運転者１２のウインドシールドガラスを通した前方及び斜め前方の視認性を更に高めることができる。 On the other hand, as shown in FIG. 6, a bonnet-type RV (leisure vehicle) vehicle with a high vehicle height is known in which a special mirror 41 is attached to the front upper surface of the left front fender 10a (for example, JP-A-8-216788). This special mirror 41 is called “a mirror for the immediately preceding left”, and is used for visually recognizing the blind spot of the driver 12 from directly under the front of the RV vehicle or the like to under the side. When evaluating the field of view of this special mirror 41, as a target object, a cylindrical body having a shoulder width and height of a Japanese 6-year-old child, that is, a cylindrical body 28 having a diameter × height of 300 mm × 1 m. (Fig. 1). The cylindrical body 28 is a pedestrian, and the pupil distance D of the driver 12 is set to 58 mm for the Japanese female pupil distance of JF5 described in [Means to be Solved by the Invention]. ) "2/3" is "x". That is, when M is calculated by substituting M = 72 mm, L 1 = 5000 mm, L 2 = 700 mm, D = 58 mm, and A = 300 mm into the above equation (1), x = 0.527. As a result, the visible part of the pedestrian 28 is (1−0.527) × 300 = 142 mm, and the Japanese female driver 12 of JF5, that is, almost all Japanese drivers are about 1 of the pedestrian 28. / 2 (47.3%) is visible. As a result, if the width M of the front corner member 16 is 72 mm, a Japanese male driver of JM50 can visually recognize the A / 3 portion of the pedestrian when the width (chest width) of the pedestrian 10 is 155 mm. When the diameter (shoulder width) of the pedestrian is 300 mm, a Japanese female driver with a narrow pupil distance can visually recognize a portion of the pedestrian about A / 2. Accordingly, the driver 12 of the truck 10 does not need to move the upper body to the left and right in order to visually recognize the other side of the front corner member 16, and only crosses the front corner member 16 by moving only the neck and looking at the direction of the front corner member 16a. The upper pedestrians 18 and 28 can be surely visually recognized, and the driver 12 can be less fatigued. If the driver 12 determines that there is no pedestrian 18 on the pedestrian crossing 21a, the driver 12 immediately turns right at the intersection 22. Further, by reducing the width of the front corner member 16 when viewed by the driver 12 to 72 mm or less, preferably more than 58 mm and 72 mm or less, both sides of the windshield glass 13 are enlarged. Both sides of the enlarged windshield glass 13 can be wiped off with a wiper and can be reliably removed with a defroster. As a result, it is possible to further improve the visibility of the driver 12 through the windshield glass in front and obliquely forward.
なお、上記第１の実施の形態では、フロントコーナ部材１６を、車外の歩行者１８のＡ／３以上の部分を視認できる幅Ｍに形成したが、フロントコーナ部材１６を、車外の歩行者１８のＡ／２以上の部分を視認できる幅Ｍに形成することが好ましい。この場合、運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅は６８ｍｍ以下、好ましくは５８ｍｍを越えかつ６８ｍｍ以下となる。このフロントコーナ部材１６の幅Ｍの最大値（６８ｍｍ）は、次の式（２）から求められる（図１、図３及び図５）。
Ｍ ＝ [〔(１／２)×Ａ−Ｄ〕／Ｌ1］×Ｌ2＋Ｄ ……（２）
上記式（２）に、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝６６ｍｍ、Ａ＝１５５ｍｍをそれぞれ代入すると、Ｍ＝６７．６１ｍｍとなり、小数点以下を切り上げてＭ＝６８ｍｍとなる。
このように構成すれば、ＪＭ５０の日本人男性の運転者１２、即ち１８才以上の全日本人男性のうちの半数の運転者１２は、上記歩行者１８のＡ／２以上の部分を視認できる。また図１の円柱体２８を歩行者とし、運転者１２の瞳孔間隔ＤをＪＦ５の日本人女性の瞳孔間隔５８ｍｍとし、上記式（２）中の『１／２』を『ｙ』とする。即ち、上記式（２）に、Ｍ＝６８ｍｍ、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝５８ｍｍ、Ａ＝３００ｍｍをそれぞれ代入してｙを求めると、ｙ＝０．４３１となる。この結果、歩行者２８の視認できる部分は（１−０．４３１）×３００＝１７１ｍｍとなり、ＪＦ５の日本人女性の運転者１２、即ち殆ど全ての日本人の運転者が歩行者２８の１／２以上（約５６％）の部分を視認できる。従って、上記第１の実施の形態より歩行者１８，２８の視認性を向上できる。
In the first embodiment, the front corner member 16 is formed to have a width M in which a portion of A / 3 or more of the pedestrian 18 outside the vehicle can be visually recognized. However, the front corner member 16 is formed of the pedestrian 18 outside the vehicle. It is preferable to form in the width | variety M which can visually recognize the part more than A / 2. In this case, the width of the front corner member 16 when viewed by the driver 12 seated in the driver's seat is 68 mm or less, preferably more than 58 mm and 68 mm or less. The maximum value (68 mm) of the width M of the front corner member 16 is obtained from the following equation (2) (FIGS. 1, 3 and 5).
M = [[(1/2) × A−D] / L 1 ] × L 2 + D (2)
Substituting L 1 = 5000 mm, L 2 = 700 mm, D = 66 mm, and A = 155 mm into the above equation (2) gives M = 67.61 mm, and rounds up the decimal point to M = 68 mm.
If comprised in this way, the driver 12 of the Japanese male of JM50, ie, the driver 12 of the half of all the Japanese males 18 years or older, can visually recognize the part of the said pedestrian 18 more than A / 2. 1 is a pedestrian, the pupil distance D of the driver 12 is 58 mm for a Japanese female JF5, and “1/2” in the above equation (2) is “y”. That is, when y is calculated by substituting M = 68 mm, L 1 = 5000 mm, L 2 = 700 mm, D = 58 mm, and A = 300 mm into the above equation (2), y = 0.431. As a result, the visible part of the pedestrian 28 is (1−0.431) × 300 = 171 mm, and the Japanese female driver 12 of JF5, that is, almost all Japanese drivers are 1 / of the pedestrian 28. Two or more (about 56%) portions can be visually recognized. Therefore, the visibility of the pedestrians 18 and 28 can be improved as compared with the first embodiment.
一方、第１の実施の形態では、歩行者１８を７才児とし、この歩行者１８の幅を運転者１２の視線方向に対して直角方向に向いた極めて稀な場合の胸幅１５５とする厳しい条件の下で説明したけれども、実際上、上記歩行者１８は様々な方向を向き、また歩行者１８がランドセル等を背負っている場合を考え合せれば、瞳孔間隔が６６ｍｍであるＪＭ５０の日本人男性の運転者にとって歩行者１８の胸幅Ａ＝１５５ｍｍのＡ／３の部分が見えれば、実用上、瞳孔間隔が６６ｍｍ以下の運転者１２であっても上記歩行者１８を十分に認識でき、大部分の運転者１２が歩行者１８を視認できる。
また歩行者２８を肩幅（直径）３００ｍｍの６才児としても、この歩行者２８の肩幅Ａ＝３００ｍｍのＡ／３の部分が見えれば、実際上の子供を視認することは可能である。ＪＭ５０の日本人男性の運転者１２にとって歩行者２８の肩幅Ａ＝３００ｍｍのＡ／３の部分が見えるフロントコーナ部材１６の幅Ｍは、次の式（１）から求めることができる。
Ｍ ＝ [〔(２／３)×Ａ−Ｄ〕／Ｌ1］×Ｌ2＋Ｄ ……（１）
上記式（１）に、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝６６ｍｍ、Ａ＝３００ｍｍをそれぞれ代入すると、Ｍ＝８４．７６ｍｍとなり、小数点以下を切り上げてＭ＝８５ｍｍとなる。フロントコーナ部材１６の幅Ｍが８５ｍｍ以下、好ましくは５８ｍｍを越えかつ８５ｍｍ以下であれば、直径３００ｍｍの対象物２８である実際上の子供を視認できる。
On the other hand, in the first embodiment, the pedestrian 18 is a 7-year-old child, and the width of the pedestrian 18 is a chest width 155 in a very rare case facing the direction perpendicular to the driver's 12 line of sight. Although explained under severe conditions, in practice, the pedestrian 18 is facing various directions, and considering the case where the pedestrian 18 carries a school bag, etc., the pupil distance is 66 mm in Japan. If a male / male driver can see the A / 3 portion of the pedestrian 18's chest width A = 155 mm, the pedestrian 18 can be sufficiently recognized even if the driver 12 has a pupil distance of 66 mm or less. Most drivers 12 can see the pedestrian 18.
Further, even if the pedestrian 28 is a 6-year-old child with a shoulder width (diameter) of 300 mm, the actual child can be visually recognized if the A / 3 portion of the pedestrian 28 with a shoulder width A = 300 mm can be seen. The width M of the front corner member 16 where the shoulder portion A = 300 mm of the pedestrian 28 can be seen by the Japanese male driver 12 of JM50 can be obtained from the following formula (1).
M = [[(2/3) × AD] / L 1 ] × L 2 + D (1)
Substituting L 1 = 5000 mm, L 2 = 700 mm, D = 66 mm, and A = 300 mm into the above equation (1) results in M = 84.76 mm, rounding up the decimal point to M = 85 mm. If the width M of the front corner member 16 is 85 mm or less, preferably more than 58 mm and 85 mm or less, the actual child that is the object 28 having a diameter of 300 mm can be visually recognized.
一方、図７に示すように、従来のフロントコーナ部材６は、第１ウエザストリップ９ａとフロントピラー７と第２ウエザストリップ９ｂとドアフレーム４ｃとガラスフレーム４ｅとガラスラン４ｆとにより構成される。この従来の小型トラックのフロントコーナ部材６の幅Ｍ、即ち第１ウエザストリップ９ａからガラスラン４ｆまでの幅Ｍを測定したところ９２〜９８ｍｍであった。上記式（１）に、Ｍ＝９２ｍｍ、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝６６ｍｍをそれぞれ代入すると、Ａ＝３７７．６ｍｍとなり、２Ａ／３＝２５１．７ｍｍとなる。また上記式（１）に、Ｍ＝９８ｍｍ、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝６６ｍｍをそれぞれ代入すると、Ａ＝４４１．９ｍｍとなり、２Ａ／３＝２９４．６ｍｍとなる。従って、車外の対象物を肩幅（直径）３００ｍｍの６才児とすると、運転者はフロントコーナ部材６により遮られて８３．９％［（２５１．７／３００）×１００］から９９．５％［（２９４．６／３００）×１００］の部分を視認できず、本発明のフロントコーナ部材の方が従来のフロントコーナ部材６より格段に視界を改善できる。なお、図７中の符号９ｃはウインドシールドガラスである。 On the other hand, as shown in FIG. 7, the conventional front corner member 6 includes a first weather strip 9a, a front pillar 7, a second weather strip 9b, a door frame 4c, a glass frame 4e, and a glass run 4f. The The width M of the front corner member 6 of this conventional small truck, that is, the width M from the first weather strip 9a to the glass run 4f was measured to be 92 to 98 mm. Substituting M = 92 mm, L 1 = 5000 mm, L 2 = 700 mm, and D = 66 mm into the above equation (1) results in A = 377.6 mm and 2A / 3 = 251.7 mm. If M = 98 mm, L 1 = 5000 mm, L 2 = 700 mm, and D = 66 mm are substituted into the above formula (1), A = 441.9 mm and 2A / 3 = 294.6 mm. Therefore, if the object outside the vehicle is a 6-year-old child with a shoulder width (diameter) of 300 mm, the driver is blocked by the front corner member 6 and 83.9% [(251.7 / 300) × 100] to 99.5%. The [(294.6 / 300) × 100] portion cannot be visually recognized, and the field of view of the front corner member of the present invention can be remarkably improved compared to the conventional front corner member 6. In addition, the code | symbol 9c in FIG. 7 is a windshield glass.
＜第２の実施の形態＞
図８は本発明の第２の実施の形態を示す。また便宜上、上記第１の実施の形態に用いた図１〜図４も利用して説明する。
この実施の形態では、車両１０の運転席に着席しかつ瞳孔間隔が５８ｍｍであるＪＦ５の日本人女性の運転者１２がフロントコーナ部材１６の方向を両眼１２ａ，１２ｂで見たときであって、フロントコーナ部材１６に向けられた運転者１２の視線上に運転者１２の瞳孔１２ｃ,１２ｄから少なくとも５ｍ離れた車外の歩行者１８（図１及び図２）が存在し、車両１０の運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅及び歩行者１８の幅をそれぞれＭ（図３）及びＡ（図１）とし、このＡが１５５ｍｍであるとき、フロントコーナ部材１６が存在しても、歩行者１８のＡ／３以上の部分を運転者１２が視認できるＭをフロントコーナ部材１６が有する。ここで、車両１０の運転者１２の瞳孔間隔を５８ｍｍに規定したのは、上記［発明が解決しようとする課題］の請求項５に記載した理由に基づく。また、歩行者１８の幅を１５５ｍｍと規定し、運転者１２の瞳孔１２ｃ，１２ｄから歩行者１８までの距離を少なくとも５ｍと規定したのは、上記［発明が解決しようとする課題］の請求項１に記載した理由に基づく。
<Second Embodiment>
FIG. 8 shows a second embodiment of the present invention. For convenience, the description will be made with reference to FIGS. 1 to 4 used in the first embodiment.
In this embodiment, the driver 12 of a Japanese female JF5 who sits in the driver's seat of the vehicle 10 and has a pupil interval of 58 mm looks at the direction of the front corner member 16 with both eyes 12a and 12b. There is a pedestrian 18 (FIGS. 1 and 2) outside the vehicle at least 5 m away from the pupils 12c and 12d of the driver 12 on the line of sight of the driver 12 directed to the front corner member 16, and the driver's seat of the vehicle 10 The width of the front corner member 16 and the width of the pedestrian 18 when viewed by the driver 12 seated in the vehicle are M (FIG. 3) and A (FIG. 1), respectively, and when this A is 155 mm, the front corner member 16 The front corner member 16 has an M that allows the driver 12 to visually recognize a portion of the pedestrian 18 that is equal to or greater than A / 3. The reason why the pupil distance of the driver 12 of the vehicle 10 is set to 58 mm is based on the reason described in claim 5 of the above [Problem to be Solved by the Invention]. Further, the width of the pedestrian 18 is defined as 155 mm, and the distance from the pupils 12c and 12d of the driver 12 to the pedestrian 18 is defined as at least 5 m. Based on the reason described in 1.
一方、トラック１０の運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅は、この実施の形態では、６５ｍｍ以下、好ましくは５８ｍｍを越えかつ６５ｍｍ以下である。この運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅とは、上記第１の実施の形態で定義した幅をいう。
上記フロントコーナ部材１６の幅Ｍの最大値（６５ｍｍ）は次の式（１）から求められる（図１、図３及び図８）。
Ｍ ＝ [〔(２／３)×Ａ−Ｄ〕／Ｌ1］×Ｌ2＋Ｄ ……（１）
上記式（１）に、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝５８ｍｍ、Ａ＝１５５ｍｍをそれぞれ代入すると、Ｍ＝６４．３５ｍｍとなり、小数点以下を切り上げてＭ＝６５ｍｍとなる。なお、運転者１２の瞳孔１２ｃ，１２ｄからフロントコーナ部材１６までの距離Ｌ2を７００ｍｍとしたのは、上記第１の実施の形態に記載した理由と同一の理由に基づく。上記以外は第１の実施の形態と同一に構成される。
On the other hand, the width of the front corner member 16 when viewed by the driver 12 seated in the driver's seat of the truck 10 is 65 mm or less, preferably more than 58 mm and 65 mm or less in this embodiment. The width of the front corner member 16 as viewed by the driver 12 seated in the driver's seat refers to the width defined in the first embodiment.
The maximum value (65 mm) of the width M of the front corner member 16 is obtained from the following equation (1) (FIGS. 1, 3, and 8).
M = [[(2/3) × AD] / L 1 ] × L 2 + D (1)
Substituting L 1 = 5000 mm, L 2 = 700 mm, D = 58 mm, and A = 155 mm into the above equation (1) results in M = 64.35 mm, rounding up the decimal point to M = 65 mm. Note that the pupil 12c of the driver 12, the distance L 2 to the front corner member 16 was set to 700mm from 12d is based on the same reasons as discussed in the first embodiment. The configuration other than the above is the same as that of the first embodiment.
このように構成されたトラック１０の動作を説明する。
図２に示すように、トラック１０が対面通行の片側一車線道路を走行し、交差点２２で右折するとき、走行道路１９の対向車線を直進する対向車が通り過ぎるまで交差点２２で停止して待つ。対向車が通り過ぎた後に、トラック１０の走行道路１９に交差する交差道路２１の右側の横断歩道２１ａ上を見て歩行者１８が横断しているか否かを確認する。このとき運転者１２がＪＦ５の日本人女性とし、この運転者１２の瞳孔１２ｃ，１２ｄから交差道路２１の右斜め前方の車外の歩行者１８までの距離Ｌ1を５ｍとし、その歩行者１８の幅Ａを日本人の７才児の胸幅Ａの平均値を１５５ｍｍとすると、ＪＦ５の日本人女性の運転者１２、即ち１８才以上の大部分の日本人の運転者１２は、フロントコーナ部材１６が存在しても、歩行者１８のＡ／３以上の部分を視認できる（図１）。具体的には、歩行者１８が運転者１２の両眼死角領域から右眼死角領域にはみ出しているため、左眼１２ａで歩行者１８のＡ／３以上の部分を視認できる。また１８才以上の日本人の瞳孔間隔には大きな差がないため、ＪＦ５の日本人女性の運転者１２が歩行者１８のＡ／３以上の部分を視認できれば、１８才以上の殆ど全ての日本人の運転者１２が歩行者１８を確実に視認できる。また１８才以上の日本人の瞳孔間隔には大きな差がないため、ＪＦ５の日本人女性の運転者１２が歩行者のＡ／３以上の部分を視認できれば、１８才以上の殆ど全ての日本人の運転者１２が歩行者１８を確実に視認できる。従って、トラック１０の運転者１２はフロントコーナ部材１６の向こう側を視認するために上体を左右に動かす必要がなく、首のみを動かしてフロントコーナ部材１６の方向を正視するだけで横断歩道２１ａ上の歩行者１８を確実に視認できるとともに、運転者１２の疲労を軽減できる。上記以外の動作は第１の実施の形態と同様であるので、繰返しの説明を省略する。
The operation of the track 10 thus configured will be described.
As shown in FIG. 2, when the truck 10 travels on a one-lane road with two-way traffic and makes a right turn at an intersection 22, the truck 10 stops at the intersection 22 and waits until an oncoming vehicle passing straight on the opposite lane of the traveling road 19 passes. After the oncoming vehicle passes, it is confirmed whether or not the pedestrian 18 is crossing by looking on the pedestrian crossing 21a on the right side of the cross road 21 that intersects the traveling road 19 of the truck 10. At this time, the driver 12 is a Japanese woman of JF5, and the distance L 1 from the pupils 12c and 12d of the driver 12 to the pedestrian 18 outside the vehicle diagonally to the right of the cross road 21 is 5 m. Assuming that the average value of the breast width A of a 7-year-old Japanese child is 155 mm, a Japanese female driver 12 of JF5, that is, most Japanese drivers 12 over 18 years old, Even if 16 is present, a portion of the pedestrian 18 of A / 3 or more can be visually recognized (FIG. 1). Specifically, since the pedestrian 18 protrudes from the binocular blind spot area of the driver 12 to the right blind spot area, the left eye 12a can visually recognize a portion of the pedestrian 18 that is A / 3 or more. Also, there is no big difference in the pupil spacing between Japanese over 18 years old, so if the Japanese female driver 12 of JF5 can see the part of the pedestrian 18 over A / 3, almost all Japanese over 18 years old The human driver 12 can reliably see the pedestrian 18. Also, there is no big difference in pupil spacing between Japanese over 18 years old, so if Japanese female driver 12 of JF5 can see the pedestrian A / 3 or higher part, almost all Japanese over 18 years old The driver 12 can visually recognize the pedestrian 18. Accordingly, the driver 12 of the truck 10 does not need to move the upper body to the left and right in order to visually recognize the other side of the front corner member 16, and only crosses the front corner member 16 by moving only the neck and looking at the direction of the front corner member 16a. The upper pedestrian 18 can be seen with certainty, and the driver 12 can be less fatigued. Since operations other than those described above are the same as those in the first embodiment, repeated description will be omitted.
なお、上記第２の実施の形態では、フロントコーナ部材１６を、車外の歩行者１８のＡ／３以上の部分を視認できる幅Ｍに形成したが、フロントコーナ部材１６を、車外の歩行者１８のＡ／２以上の部分を視認できる幅Ｍに形成することが好ましい。この場合、運転席に着席した運転者１２が見たときのフロントコーナ部材１６の幅は６１ｍｍ以下、好ましくは５８ｍｍを越えかつ６１ｍｍ以下となる。このフロントコーナ部材１６の幅Ｍの最大値（６１ｍｍ）は次の式（２）から求められる（図１、図３及び図８）。
Ｍ ＝ [〔(１／２)×Ａ−Ｄ〕／Ｌ1］×Ｌ2＋Ｄ ……（２）
上記式（２）に、Ｌ1＝５０００ｍｍ、Ｌ2＝７００ｍｍ、Ｄ＝５８ｍｍ、Ａ＝１５５ｍｍをそれぞれ代入すると、Ｍ＝６０．７３ｍｍとなり、小数点以下を切り上げてＭ＝６１ｍｍとなる。
このように構成すれば、ＪＦ５の日本人女性の運転者１２、即ち１８才以上の殆ど全ての日本人の運転者１２は、上記歩行者１８のＡ／２以上の部分を視認できるので、上記第２の実施の形態より歩行者１８の視認性を向上できる。
また、上記第１及び第２の実施の形態では、車両としてトラックを挙げたが、乗用車又はバスでもよい。
また、車両の運転者が外国人であっても、この外国人の瞳孔間隔は日本人の運転者の瞳孔間隔とさほど変わらず、対象物が外国人の７才児であっても、この外国人の７才児の胸幅は日本人の７才児の胸幅と殆ど変わらず、対象物が外国人の６才児であっても、この外国人の６才児の肩幅は日本人の６才児の肩幅と殆ど変わらないため、本発明は日本国内だけでなく外国においても適用でき、上記と同等の効果が得られる。
更に、上記第１及び第２の実施の形態では、車両として右側に運転席を有する車両、いわゆる右ハンドル車両を挙げたが、左側に運転席を有する車両、いわゆる左ハンドル車両にも本発明を適用できる。この場合、運転席側、即ち左側のフロントコーナ部材に本発明が適用される。
In the second embodiment, the front corner member 16 is formed to have a width M in which a portion of A / 3 or more of the pedestrian 18 outside the vehicle can be visually recognized. However, the front corner member 16 is formed of the pedestrian 18 outside the vehicle. It is preferable to form in the width | variety M which can visually recognize the part more than A / 2. In this case, the width of the front corner member 16 when viewed by the driver 12 seated in the driver's seat is 61 mm or less, preferably more than 58 mm and 61 mm or less. The maximum value (61 mm) of the width M of the front corner member 16 is obtained from the following equation (2) (FIGS. 1, 3, and 8).
M = [[(1/2) × A−D] / L 1 ] × L 2 + D (2)
Substituting L 1 = 5000 mm, L 2 = 700 mm, D = 58 mm, and A = 155 mm into the above equation (2), M = 60.73 mm is obtained, and the decimal part is rounded up to M = 61 mm.
If comprised in this way, since the driver 12 of a Japanese woman of JF5, ie, almost all Japanese drivers 12 or older, can visually recognize the part of the pedestrian 18 that is A / 2 or more, The visibility of the pedestrian 18 can be improved as compared with the second embodiment.
Moreover, in the said 1st and 2nd embodiment, although the truck was mentioned as a vehicle, a passenger car or a bus | bath may be sufficient.
