Description

本発明は、車両用歩行者保護装置に係り、特に、車両前部の下部部位に設置されて、車両前面に衝突乃至は接触した歩行者の脚部に接触することにより、かかる脚部を払って、歩行者の脚部を保護する車両用歩行者保護装置の改良された構造に関するものである。   The present invention relates to a pedestrian protection device for a vehicle, and in particular, the pedestrian protection device for a pedestrian installed in a lower part of the front portion of the vehicle and contacting or contacting the pedestrian's leg that hits the front of the vehicle. The present invention relates to an improved structure of a vehicle pedestrian protection device for protecting a pedestrian's legs.

従来から、自動車等の車両においては、衝突時に生ずる衝撃エネルギーを吸収し、車体や乗員を保護することを主な目的として、車両の前面や後面、或いは側面等に、各種の保護装置が設置されている。また、近年では、車両の前面に歩行者が衝突（接触）した際に歩行者を保護する装置も、車両前面に設置されるようになってきている。   Conventionally, in vehicles such as automobiles, various protection devices have been installed on the front, rear, or side surfaces of the vehicle mainly for the purpose of absorbing impact energy generated in the event of a collision and protecting the vehicle body and passengers. ing. In recent years, a device for protecting a pedestrian when a pedestrian collides (contacts) with the front of the vehicle has also been installed on the front of the vehicle.

そのような車両用歩行者保護装置（以下からは、単に、歩行者保護装置と言う）の一種として、所謂脚払い装置が、知られている。この脚払い装置は、一般に、フロントバンパの内側やフロントバンパよりも下部側の部位等、車両前部の下部部位に設置される。そして、歩行者が車両前面に衝突したときに、前端において、歩行者の脚部に接触することにより、歩行者の脚部を払って（すくい上げて）、歩行者をボンネット等の衝撃吸収可能な部材側に転倒させ、以て、歩行者の保護及び安全を図るようにしたものである。   As a kind of such a vehicle pedestrian protection device (hereinafter, simply referred to as a pedestrian protection device), a so-called leg cleaning device is known. In general, the leg cleaning device is installed in a lower part of the front portion of the vehicle, such as an inner side of the front bumper or a lower part of the front bumper. When the pedestrian collides with the front of the vehicle, the pedestrian can be absorbed by a bonnet or the like by touching the pedestrian's leg at the front end. It is intended to protect the pedestrian and ensure safety by falling to the member side.

ところで、歩行者保護装置には、前端部に接触した歩行者の脚部のダメージをできるだけ軽減し得る構造を有していることが、要求される。そこで、例えば、特開２００７−５５５４３号公報（特許文献１）や特開２０１０−１７９６７１号公報（特許文献２）等には、そのような要求性能を満たし得る歩行者保護装置として、補強部が設けられた前側部分と、車両前部に設置された車両部品に取り付けられる後側部分とを一体的に有して、車両前部の下部部位に車両前後方向に延びるように配置される樹脂成形体にて構成されたものが、提案されている。   By the way, the pedestrian protection device is required to have a structure that can reduce damage to the leg of the pedestrian that has contacted the front end as much as possible. Therefore, for example, in Japanese Unexamined Patent Application Publication No. 2007-55543 (Patent Document 1) and Japanese Unexamined Patent Application Publication No. 2010-179671 (Patent Document 2), a reinforcing portion is provided as a pedestrian protection device that can satisfy such required performance. A resin molding that integrally has a provided front portion and a rear portion that is attached to a vehicle part installed at the front of the vehicle, and is arranged to extend in the vehicle front-rear direction at a lower portion of the front of the vehicle What is composed of the body has been proposed.

すなわち、前者の公報に開示された歩行者保護装置は、車両前部の下部部位に車両前後方向に延びるように配置される平板状の樹脂製基板を有している。そして、この基板が、その後部において、車両部品にボルト固定されるようになっている。かかる基板の前部には、一方の板面の車幅方向に間隔を隔てた複数箇所に、平板状の縦リブが、車幅方向において互いに対向して車両前後方向に延びるように一体形成されている。また、基板前部における複数の縦リブの対向面間には、車幅方向に延びる平板状の横リブが、互いに対向する縦リブ同士を相互に連結するように一体形成されている。かくして、かかる歩行者保護装置では、基板前部に、複数の縦リブと複数の横リブとが組み合されてなるリブ構造体が設けられている。また、このリブ構造体にて、歩行者保護装置の前側部分に、補強部が形成されている。そして、この補強部によって、前側部分の剛性、即ち、車両前側から後側に向かう荷重に対する変形強度の増大が図られている。   That is, the pedestrian protection device disclosed in the former publication has a flat resin-made substrate that is arranged in the lower part of the front portion of the vehicle so as to extend in the vehicle front-rear direction. And this board | substrate is bolt-fixed to vehicle components in the rear part. On the front portion of the board, flat plate-like vertical ribs are integrally formed at a plurality of positions spaced in the vehicle width direction on one plate surface so as to face each other in the vehicle width direction and extend in the vehicle front-rear direction. ing. Further, between the opposing surfaces of the plurality of vertical ribs in the front portion of the board, flat plate-like horizontal ribs extending in the vehicle width direction are integrally formed so as to mutually connect the vertical ribs facing each other. Thus, in such a pedestrian protection apparatus, a rib structure formed by combining a plurality of vertical ribs and a plurality of horizontal ribs is provided in the front portion of the board. Moreover, the reinforcement part is formed in the front side part of a pedestrian protection apparatus by this rib structure. And the rigidity of the front part, ie, the deformation | transformation strength with respect to the load which goes to a rear side from the vehicle front side, is increased by this reinforcement part.

一方、後者の公報に開示された歩行者保護装置においては、樹脂製の基板の前部に、縦断面コ字形状をもって上方に突出し、下方に開口して、車両前後方向に延びる複数の上側補強ビードと、縦断面コ字形状をもって下方に突出し、上方に開口して、車両前後方向に延びる複数の下側補強ビードとが、車幅方向に１個ずつ交互に並んで位置するように一体形成されている。また、それら上側及び下側補強ビードのそれぞれの内側には、各補強ビードの互いに対向する縦壁部（縦リブ）間に跨って、車幅方向に延びる連結リブが、それら縦壁部同士を相互に連結するように一体形成されている。即ち、この歩行者保護装置では、その前側部分に、補強部が、基板前部に設けられた複数の上側及び下側補強ビードと複数の連結リブとによって形成されている。そして、それにより、歩行者保護装置の前側部分の剛性（車両前側から後側に向かう荷重に対する変形強度）が高められている。   On the other hand, in the pedestrian protection device disclosed in the latter publication, a plurality of upper reinforcements projecting upward with a U-shaped longitudinal section at the front portion of the resin substrate, opening downward, and extending in the vehicle longitudinal direction A bead and a plurality of lower reinforcing beads that protrude downward with a U-shaped longitudinal section, open upward, and extend in the longitudinal direction of the vehicle are integrally formed so as to be alternately arranged one by one in the vehicle width direction. Has been. In addition, on each inner side of the upper and lower reinforcing beads, connecting ribs extending in the vehicle width direction across the vertical wall portions (vertical ribs) facing each other of the reinforcing beads extend between the vertical wall portions. It is integrally formed so that it may mutually connect. That is, in this pedestrian protection apparatus, the reinforcing portion is formed on the front portion thereof by a plurality of upper and lower reinforcing beads and a plurality of connecting ribs provided at the front portion of the board. And thereby, the rigidity of the front portion of the pedestrian protection device (the deformation strength with respect to the load from the vehicle front side to the rear side) is enhanced.

このように、従来の歩行者保護装置にあっては、前側部分に補強部が設けられて、かかる前側部分の剛性が高められており、それによって、歩行者の脚部が接触したときに生ずる衝撃荷重と、歩行者保護装置の変形量（変位量）との関係を示す荷重−変位曲線の形状が、理想的な矩形波に近付けられている。そして、その結果、歩行者の脚部の接触によって生ずる衝撃が、より効率的且つ十分に吸収され、以て、歩行者の脚部のダメージが効果的に軽減され得るようになっているのである。   Thus, in the conventional pedestrian protection device, the reinforcing portion is provided in the front side portion, and the rigidity of the front side portion is enhanced, thereby causing the pedestrian's leg portion to come into contact. The shape of the load-displacement curve indicating the relationship between the impact load and the deformation amount (displacement amount) of the pedestrian protection device is approaching an ideal rectangular wave. As a result, the impact caused by the contact of the pedestrian's legs is absorbed more efficiently and sufficiently, so that damage to the pedestrian's legs can be effectively reduced. .

ところが、上記した従来の歩行者保護装置の構造について、本発明者が、様々な角度から検討を加えたところ、以下のような問題が内在していることが判明した。   However, when the present inventors have studied the structure of the above-described conventional pedestrian protection device from various angles, it has been found that the following problems are inherent.

すなわち、車両前部の下部部位に設置された歩行者保護装置は、通常、車両の走行時に、その上面と下面の両方において走行風を受ける。そのため、そのような歩行者保護装置は、歩行者保護を可能とする構造に加えて、上面と下面とが、走行風をスムーズに後方に導き得るような構造を有していることが望ましい。何故なら、それにより、車両の空力性能が高められて、燃費の向上が効果的に図られ得るからである。   That is, the pedestrian protection device installed in the lower part of the front part of the vehicle usually receives traveling wind on both the upper surface and the lower surface when the vehicle travels. Therefore, it is desirable that such a pedestrian protection device has a structure in which the upper surface and the lower surface can smoothly guide the traveling wind backward in addition to the structure that enables pedestrian protection. This is because it can improve the aerodynamic performance of the vehicle and effectively improve the fuel consumption.

しかしながら、前記した従来の歩行者保護装置においては、その前側部分に設けられた補強部が、前側部分の上面や下面において車幅方向に延びる平板状の横リブや連結リブを含んで構成されている。そのため、そのような従来の歩行者保護装置を車両前部の下部部位に設置した場合、車両の走行時に、走行風が、横リブや連結リブに衝突してしまい、それら横リブや連結リブによって、走行風の流れが遮られるようになる。即ち、従来の歩行者保護装置では、横リブや連結リブが空力抵抗となっており、それ故に、走行風をスムーズに後方に導くことが困難であった。従って、従来の歩行者保護装置は、車両前部の下部部位への設置によって、歩行者の保護を十分に且つ確実に実現できるものの、車両下部の空力性能を低下させる可能性があったのである。   However, in the above-described conventional pedestrian protection device, the reinforcing portion provided in the front portion thereof is configured to include flat plate-like lateral ribs and connecting ribs extending in the vehicle width direction on the upper surface and the lower surface of the front portion. Yes. Therefore, when such a conventional pedestrian protection device is installed in the lower part of the front part of the vehicle, the traveling wind collides with the lateral ribs and the connecting ribs when the vehicle travels, and these lateral ribs and the connecting ribs As a result, the flow of the traveling wind is blocked. That is, in the conventional pedestrian protection device, the lateral ribs and the connecting ribs have aerodynamic resistance, and therefore it is difficult to smoothly guide the traveling wind backward. Therefore, although the conventional pedestrian protection device can sufficiently and reliably realize the protection of the pedestrian by being installed in the lower part of the front part of the vehicle, there is a possibility that the aerodynamic performance of the lower part of the vehicle is lowered. .

特開２００７−５５５４３号公報JP 2007-55543 A 特開２０１０−１７９６７１号公報JP 2010-179671 A

ここにおいて、本発明は、上述せる如き事情を背景にして為されたものであって、その解決課題とするところは、歩行者の保護を十分に且つ確実に達成できるだけでなく、空力抵抗が可及的に小さくされることにより、車両下部の空力性能を効果的に高め得るように改良された車両用歩行者保護装置の構造を提供することにある。   Here, the present invention has been made in the background as described above, and the problem to be solved is that not only can pedestrian protection be achieved sufficiently and reliably, but also aerodynamic resistance is possible. An object of the present invention is to provide a structure of a vehicle pedestrian protection device which is improved so as to effectively improve the aerodynamic performance of the lower part of the vehicle by being made as small as possible.

そして、本発明にあっては、上記の課題の解決のために、補強部が設けられた前側部分と、車両前部に設置された車両部品に取り付けられる後側部分とを一体的に有して、車両の前部の下部部位に車両前後方向に延びるように配置される樹脂成形体からなり、前端部が、車両の前面に衝突した歩行者の脚部に接触することによって、該脚部を保護し得るように構成された車両用歩行者保護装置であって、（ａ）前記前側部分の車幅方向に間隔を隔てた少なくとも三箇所に、車幅方向において互いに対向して車両前後方向に延びるようにそれぞれ配置された複数の縦リブと、（ｂ）それら複数の縦リブの全ての上端部に跨るように横架した状態で、車両前後方向に延びるように配置されて、該複数の縦リブの上端部同士を一体的に連結する上側連結板部と、（ｃ）該複数の縦リブの全ての下端部に跨るように横架した状態で、車両前後方向に延びるように配置されて、該複数の縦リブの下端部同士を一体的に連結する下側連結板部とによって、前記前側部分に、車両前後方向に延びる筒状構造体が、車幅方向に並んで複数形成されて、前記補強部が、それら複数の筒状構造体にて構成されており、且つ前記互いに対向する縦リブの前記上端部同士の間に位置する複数の前記上側連結板部部位のうちの少なくとも一つと、該互いに対向する縦リブの前記下端部同士の間に位置する複数の前記下側連結板部部位のうちの少なくとも一つの両方、又はそれらのうちの何れか一方が、縦断面コ字状を呈する屈曲板部とされていることを特徴とする車両用歩行者保護装置を、その要旨とするものである。   And in this invention, in order to solve said subject, it has integrally the front side part provided with the reinforcement part, and the rear side part attached to the vehicle components installed in the vehicle front part. The front end of the vehicle is in contact with the leg of a pedestrian that has collided with the front of the vehicle. The vehicle pedestrian protection device is configured to protect the vehicle, and (a) at least three points spaced apart in the vehicle width direction of the front side portion so as to face each other in the vehicle width direction. A plurality of vertical ribs each extending so as to extend to the vehicle, and (b) arranged so as to extend in the vehicle front-rear direction in a state of being laid across all upper ends of the plurality of vertical ribs. The upper side that integrally connects the upper ends of the vertical ribs A connecting plate part, and (c) arranged so as to extend in the vehicle front-rear direction in a state of being laid across all the lower ends of the plurality of vertical ribs, and integrally connecting the lower ends of the plurality of vertical ribs. A plurality of cylindrical structures extending in the vehicle front-rear direction are formed on the front side portion side by side in the vehicle width direction, and the reinforcing portion is formed of the plurality of cylindrical structures. At least one of the plurality of upper connecting plate portions located between the upper end portions of the vertical ribs facing each other, and the lower end portion of the vertical ribs facing each other At least one of the plurality of lower connection plate portions located between each other, or any one of them is a bent plate portion having a U-shaped longitudinal section. The gist of the vehicle pedestrian protection device A.

本発明の好ましい態様の一つによれば、前記上側連結板部が、前記縦リブの前後方向の延出長さよりも長い延出長さを有するように構成される。   According to one of the preferable aspects of the present invention, the upper connecting plate portion is configured to have an extension length that is longer than the extension length of the longitudinal rib in the front-rear direction.

本発明の好適な態様の一つによれば、前記縦リブが、前記下側連結板部の前端位置から前記後側部分の前記車両への取付箇所の近傍位置にまで達する前後方向の延出長さを有して、構成される。   According to one of the preferable aspects of the present invention, the longitudinal rib extends in the front-rear direction from the front end position of the lower connecting plate portion to a position near the attachment position of the rear portion to the vehicle. It has a length and is configured.

本発明の有利な態様の一つによれば、前記上側連結板部と前記下側連結板部のうちの少なくとも何れか一方が、前記後側部分の車両部品への取付状態下で、該車両部品の車両前方に配置される当接部を有すると共に、該後側部分の車両部品への取付状態下において、或いは該当接部を有する該上側連結板部又は該下側連結板部が前記前側部分への歩行者の衝突により後方に変位したときに、該当接部が、該車両部品に当接するように構成される。   According to one of the advantageous aspects of the present invention, at least one of the upper connecting plate portion and the lower connecting plate portion is mounted on the vehicle when the rear portion is attached to a vehicle component. The front connection plate portion or the lower connection plate portion having the contact portion disposed in front of the vehicle and having the rear portion attached to the vehicle component or having the corresponding contact portion is the front side. The corresponding contact portion is configured to come into contact with the vehicle component when displaced rearward due to a pedestrian collision with the portion.

すなわち、本発明に従う車両用歩行者保護装置にあっては、前側部分に、前後方向に延びる複数の筒状構造体からなる補強部が形成されている。これによって、前側部分の、車両前側から後側に向かう荷重に対する変形強度が、十分に大きくされている。   That is, in the vehicle pedestrian protection device according to the present invention, the front portion is formed with a reinforcing portion made of a plurality of cylindrical structures extending in the front-rear direction. Thereby, the deformation strength of the front portion with respect to the load from the vehicle front side to the rear side is sufficiently increased.

しかも、補強部を形成する複数の縦リブと上側及び下側連結板部が、何れも、車両前後方向に延びるように配置されている。また、複数の縦リブは、車幅方向において互いに対向配置され、上側連結板部と下側連結板部は、上下方向において互いに対向配置されている。このため、かかる車両用歩行者保護装置においては、従来装置とは異なって、板面を前後方向に向けて、車幅方向に延びる横リブや連結リブのように、走行風に衝突して、走行風の流れを遮るように配設された部材や部位が、補強部を有する前側部分に、何等形成されていない。それ故、前側部分の空力抵抗が十分に小さくされて、走行風の後方へのスムーズな流れが、安定的に確保され得る。   Moreover, the plurality of vertical ribs and the upper and lower connecting plate portions that form the reinforcing portion are all arranged so as to extend in the vehicle front-rear direction. The plurality of vertical ribs are arranged to face each other in the vehicle width direction, and the upper connecting plate portion and the lower connecting plate portion are arranged to face each other in the vertical direction. For this reason, in such a vehicle pedestrian protection device, unlike the conventional device, the plate surface is directed in the front-rear direction, and collides with the traveling wind like a lateral rib or a connecting rib extending in the vehicle width direction, No member or part disposed so as to block the flow of the traveling wind is formed on the front part having the reinforcing part. Therefore, the aerodynamic resistance of the front portion is sufficiently reduced, and a smooth flow to the rear of the traveling wind can be stably ensured.

従って、本発明に従う車両用歩行者保護装置にあっては、車両前部の下部部位への設置によって、歩行者を十分に且つ確実に保護することができ、しかも、従来装置に比して、車両下部の空力性能を効果的に高めることができるのである。   Therefore, in the pedestrian protection device for a vehicle according to the present invention, the pedestrian can be sufficiently and reliably protected by the installation in the lower part of the front portion of the vehicle, and moreover, compared to the conventional device, It is possible to effectively enhance the aerodynamic performance of the lower part of the vehicle.

一方、脚払い装置１０の取付板部１４を除く前側部分は、補強部１８とされている。そして、本実施形態では、この補強部１８が、従来品には見られない特別な構造を有しているのである。   On the other hand, the front side portion of the leg cleaning device 10 excluding the mounting plate portion 14 is a reinforcing portion 18. And in this embodiment, this reinforcement part 18 has a special structure which is not seen in a conventional product.

すなわち、補強部１８は、下側連結板部２０と、この下側連結板部２０に対して上方に所定距離を隔てて対向配置された上側連結板部２２と、それら上側連結板部２２と下側連結板部２０との対向面間に立設された複数（ここでは、１４個）の縦リブ２４とを一体的に有している。   That is, the reinforcing portion 18 includes a lower connecting plate portion 20, an upper connecting plate portion 22 disposed to face the lower connecting plate portion 20 at a predetermined distance upward, and the upper connecting plate portion 22. A plurality of (here, 14) vertical ribs 24 are provided integrally between the opposing surfaces of the lower connecting plate portion 20.

より詳細には、下側連結板部２０は、取付板部１４の前端から前方に一体で延びる横長矩形の平板からなり、取付板部１４と略同一の厚さ及び左右方向寸法（車幅方向の延出長さ）を有している。つまり、ここでは、下側連結板部２０と取付板部１４とが一枚の板材からなる単一部材にて構成されている。また、この下側連結板部２０は、その前端面の形状が、フロントバンパ１２の内面形状に対応した凸状湾曲面形状とされている。   More specifically, the lower connecting plate portion 20 is formed of a horizontally long rectangular plate integrally extending forward from the front end of the mounting plate portion 14, and has substantially the same thickness and lateral dimensions as the mounting plate portion 14 (vehicle width direction). Extension length). That is, here, the lower connecting plate portion 20 and the mounting plate portion 14 are configured by a single member made of a single plate material. Further, the lower connecting plate portion 20 has a front end surface that is a convex curved surface corresponding to the inner surface of the front bumper 12.

下側連結板部２０の上面の前端には、前側壁部２６が、一体的に立設されている。この前側壁部２６は、上方に所定高さで突出し、且つ前側壁部２６の前端縁に沿って、湾曲しつつ、左右方向に連続して全長に延びる湾曲板材からなり、下側連結板部２０と略同一の厚さを有している。そして、このような前側壁部２６の前面が、下側連結板部２０の前端面と一体で、フロントバンパ１２の内面形状に対応した凸状湾曲面形状を呈する衝撃入力面２８とされている。   A front side wall portion 26 is erected integrally at the front end of the upper surface of the lower connecting plate portion 20.

Among the plurality of cylindrical structures 34, those adjacent to each other are the vertical ribs 24 constituting the right wall portion of the cylindrical structure 34 located on the left side of them, and among them, The upper connecting plate portion 22a and the lower connecting plate portion 20a are connected to each other between the vertical rib 24 constituting the left side wall portion of the cylindrical structure 34 located on the right side. Thus, the reinforcing portion 18 is formed by a plurality of cylindrical structures 34 connected to each other by the upper connecting plate portion portion 22a and the lower connecting plate portion portion 20a.

そして、本実施形態の脚払い装置１０では、補強部１８の左右に隣り合う縦リブ２４と、それらを相互に連結する上側及び下側連結板部部位２２ａ，２０ａとが、従来の脚払い装置の、リブ構造体からなる補強部の縦リブと横リブの役割を、それぞれ果たしている。また、左右に隣り合う二つの縦リブ２４，２４と、それらの上端部同士を連結する上側連結板部部位２２ａとにて構成される断面コ字状部分が、従来の脚払い装置の補強部に設けられる補強ビードの役割を果たし、更に、下側連結板部部位２０ａが、補強ビードの縦壁部（縦リブ）同士を連結する連結リブの役割を果たしている。   In the leg cleaning device 10 of the present embodiment, the vertical ribs 24 adjacent to the left and right of the reinforcing portion 18 and the upper and lower connecting plate portions 22a and 20a that connect them to each other include the conventional leg cleaning device. These serve as the vertical ribs and horizontal ribs of the reinforcing portion made of the rib structure. In addition, the U-shaped section formed by the two vertical ribs 24, 24 adjacent to the left and right and the upper connecting plate portion 22a that connects the upper ends of the vertical ribs 24, 24 is a reinforcing portion of the conventional leg cleaning device. In addition, the lower connecting plate portion 20a serves as a connecting rib that connects the vertical wall portions (vertical ribs) of the reinforcing beads.

従って、かかる脚払い装置１０においては、補強部１８の剛性（変形強度）、具体的には、複数の筒状構造体３４の延出方向となる前後方向に入力される衝撃荷重に対する剛性が、従来の脚払い装置の、リブ構造体からなる補強部や、複数の補強ビードと連結リブとを備えた補強部の剛性と略同程度の十分な大きさとされているのである。   Therefore, in the leg-pasting device 10, the rigidity (deformation strength) of the reinforcing portion 18, specifically, the rigidity against the impact load input in the front-rear direction, which is the extending direction of the plurality of cylindrical structures 34, The conventional leg washer has a sufficient size substantially equal to the rigidity of the reinforcing portion including the rib structure and the reinforcing portion including a plurality of reinforcing beads and connecting ribs.

かくの如き構造を有する脚払い装置１０は、例えば、図４に示されるように、自動車の前部に位置するエンジンルーム：Ｅ内において、自動車の前面に設置されたフロントバンパ１２の後方側に取り付けられるようになっている。   As shown in FIG. 4, for example, as shown in FIG. 4, the leg cleaning device 10 having such a structure is disposed in the rear of a front bumper 12 installed in the front of the automobile in an engine room E located at the front of the automobile. It can be attached.

すなわち、脚払い装置１０が内側に取り付けられるフロントバンパ１２は、全体として、車幅方向に湾曲して延びる湾曲形態を呈し、自動車前面から突出する上側突出部３６と下側突出部３８とを有している。それら上側突出部３６と下側突出部３８は、何れも、鉛直縦断面が、前方に向かって凸となる湾曲形状とされている。また、フロントバンパ１２の下側突出部３８よりも上側の部位には、外部からエンジンルーム：Ｅ内に走行風を取り入れるための空気取入口３９が、上側突出部３６にまで達する大きさを有して、形成されている。そして、かかるフロントバンパ１２は、自動車の前面部分を構成する、例えばフロントグリル４０に対してボルト固定等されて、設置されている。   That is, the front bumper 12 to which the leg wiper 10 is attached inside has a curved shape extending in the vehicle width direction as a whole, and has an upper protrusion 36 and a lower protrusion 38 that protrude from the front of the automobile. doing. Each of the upper protruding portion 36 and the lower protruding portion 38 has a curved shape in which the vertical longitudinal section is convex toward the front. In addition, an air intake 39 for taking in the traveling wind into the engine room E from the outside has a size that reaches the upper protrusion 36 at a portion above the lower protrusion 38 of the front bumper 12. And formed. The front bumper 12 is installed by being bolted to the front grill 40, for example, constituting the front portion of the automobile.

フロントバンパ１２の後方のエンジンルーム：Ｅ内には、ラジエータ４２が、配置されている。このラジエータ４２は、エンジンルーム：Ｅ内に固設されたラジエータサポート４４上に、枠状乃至は筒状のシュラウド４６内に収容された状態で支持されて、固定されている。なお、図４中、４８は、ボンネットである。   A radiator 42 is arranged in the engine room E behind the front bumper 12. The radiator 42 is supported and fixed on a radiator support 44 fixed in the engine room E, while being accommodated in a frame-shaped or cylindrical shroud 46. In FIG. 4, reference numeral 48 denotes a bonnet.

そして、脚払い装置１０は、エンジンルーム：Ｅ内の下部部位において、フロントバンパ１２とラジエータサポート４４との間に、前後方向に延びるように配置される。また、そのような状態において、補強部１８を構成する複数の筒状構造体３４の前端部が、フロントバンパ１２の下側突出部３８の内側に突入している一方、取付板部１４が、ラジエータサポート４４の下方に配置される。そして、取付板部１４が、複数の後側及び前側挿通孔１５，１６にそれぞれ挿通された取付ボルト５０により、ラジエータサポート４４の前面と後面から一体で延び出す取付フランジ部５２，５２に固定される。なお、このことから明らかなように、本実施形態では、取付板部１４の前側挿通孔１６と後側挿通孔１５の形成箇所が、それぞれ、取付板部１４の自動車への取付箇所とされている。   The leg wiper 10 is arranged between the front bumper 12 and the radiator support 44 so as to extend in the front-rear direction in the lower part of the engine room E. Further, in such a state, the front end portions of the plurality of cylindrical structures 34 constituting the reinforcing portion 18 protrude inside the lower protruding portion 38 of the front bumper 12, while the mounting plate portion 14 is It is disposed below the radiator support 44. The mounting plate portion 14 is fixed to mounting flange portions 52 and 52 extending integrally from the front surface and the rear surface of the radiator support 44 by mounting bolts 50 respectively inserted into the plurality of rear and front insertion holes 15 and 16. The As is clear from this, in the present embodiment, the formation positions of the front insertion hole 16 and the rear insertion hole 15 of the attachment plate portion 14 are the attachment locations of the attachment plate portion 14 to the automobile, respectively. Yes.

かくして、脚払い装置１０が、自動車前部の下部部位において、フロントバンパ１２の下側突出部３８とラジエータサポート４４との間に、複数の筒状構造体３４を、前後方向、つまり、歩行者のフロントバンパ１２への衝突に伴って生ずる衝撃荷重の入力方向に延びるように位置させた状態で、設置される。そして、そのような脚払い装置１０の設置状態下で、補強部１８の前側壁部２６の衝撃入力面２８が、フロントバンパ１２の下側突出部３８の内側に、衝撃荷重の入力方向に直交して、位置固定に配置される。   Thus, the leg wiping device 10 has a plurality of tubular structures 34 arranged in the front-rear direction, that is, a pedestrian, between the lower protrusion 38 of the front bumper 12 and the radiator support 44 in the lower part of the front part of the automobile. It is installed in a state where it is positioned so as to extend in the input direction of the impact load that is generated when the front bumper 12 collides. Then, under such an installation state of the leg wiping device 10, the impact input surface 28 of the front side wall portion 26 of the reinforcing portion 18 is orthogonal to the input direction of the impact load inside the lower protrusion 38 of the front bumper 12. Thus, the position is fixed.

それ故、本実施形態の脚払い装置１０にあっては、自動車前部への設置状態下で、歩行者の脚部がフロントバンパ１２に接触乃至は衝突せしめられた際に、その衝撃荷重に対する反力を、歩行者の脚部のすね付近の部分に対して、補強部１８の前側壁部２６の衝撃入力面２８からフロントバンパ１２を介して作用させ得るようになっている。このとき、脚払い装置１０の前側部分を形成する補強部１８が、衝撃荷重の入力方向に延びる複数の筒状構造体３４にて構成されて、かかる補強部１８の剛性（変形強度）が十分に確保されているところから、脚払い装置１０が容易に変形しない。このため、フロントバンパ１２に接触乃至は衝突した歩行者は、脚部のすね付近の部分が脚払い装置１０にて払われて（すくい上げられて）、ボンネット４８等の衝撃吸収可能な部材側に転倒する。これにより、歩行者の保護が図られて、その安全が効果的に確保されるようになる。   Therefore, in the leg wiping device 10 of the present embodiment, when the pedestrian's leg is brought into contact with or collided with the front bumper 12 under the installation state in the front part of the automobile, the impact load is not affected. The reaction force can be applied to the portion near the shin of the leg portion of the pedestrian from the impact input surface 28 of the front side wall portion 26 of the reinforcing portion 18 via the front bumper 12. At this time, the reinforcing portion 18 that forms the front portion of the leg cleaning device 10 is composed of a plurality of cylindrical structures 34 extending in the input direction of the impact load, and the rigidity (deformation strength) of the reinforcing portion 18 is sufficient. Therefore, the leg cleaning device 10 is not easily deformed. For this reason, a pedestrian who has contacted or collided with the front bumper 12 has its leg portion near the shin removed by the leg washer 10 (taken up) to the side of the bonnet 48 or the like that can absorb shock. Falls. Thereby, protection of a pedestrian is aimed at and the safety | security comes to be ensured effectively.

また、かかる脚払い装置１０においては、自動車前部への設置状態下で、補強部１８の上側連結板部２２の後端面が、ラジエータサポート４４上のシュラウド４６やラジエータ４２の前面に対して、僅かな距離を隔てて対向位置させた状態で配置される。これにより、上側連結板部２２の上面からなる上側導風面３２が、エンジンルーム：Ｅ内の下部部位におけるフロントバンパ１２の後面（内面）からラジエータ４２の前面までの略全領域に亘って、水平方向に広がるように配置される。また、下側連結板部２０の下面からなる下側導風面３０が、エンジンルーム：Ｅの外部において、水平方向に広がるように配置される。   Further, in such a leg washer 10, the rear end surface of the upper connecting plate portion 22 of the reinforcing portion 18 is placed on the front surface of the shroud 46 and the radiator 42 on the radiator support 44 under the installation state on the front portion of the automobile. It arrange | positions in the state made to oppose with a small distance. As a result, the upper air guide surface 32 formed from the upper surface of the upper connecting plate portion 22 extends over substantially the entire region from the rear surface (inner surface) of the front bumper 12 to the front surface of the radiator 42 in the lower portion of the engine room E. It is arranged to spread horizontally. Further, the lower air guide surface 30 formed by the lower surface of the lower connecting plate portion 20 is arranged outside the engine room: E so as to spread in the horizontal direction.

このため、本実施形態の脚払い装置１０は、自動車前部に設置された状態下において、フロントバンパ１２の空気取入口３９から取り入れられた走行風を、上側導風面３２にて案内しつつ、ラジエータ４２の前面にスムーズに導くことができる。また、フロントバンパ１２の下側を通過する走行風を、下側導風面３０にて案内しつつ、後方側に送り出すことができる。   For this reason, the leg wiper 10 according to the present embodiment guides the traveling wind taken from the air intake port 39 of the front bumper 12 by the upper air guide surface 32 while being installed in the front part of the automobile. , Can be smoothly guided to the front surface of the radiator 42. Further, the traveling wind passing through the lower side of the front bumper 12 can be sent to the rear side while being guided by the lower air guide surface 30.

従って、本実施形態の脚払い装置１０にあっては、自動車前部の下部部位への設置状態下で、自動車前部の下部部位の空力抵抗を十分に低下させて、自動車下部の空力性能を効果的に高めることができ、それによって、燃費の向上を有利に達成できるのである。   Therefore, in the leg cleaning device 10 of the present embodiment, the aerodynamic performance of the lower part of the automobile is reduced by sufficiently reducing the aerodynamic resistance of the lower part of the front part of the automobile under the installation state in the lower part of the front part of the automobile. It can be effectively increased, thereby advantageously improving fuel efficiency.

しかも、脚払い装置１０は、上側連結板部２２の前後方向寸法が、縦リブの２４の前後方向寸法よりも長くされている。また、下側連結板部２０と取付板部１４とが１枚の板材からなる単一部材にて構成されている。これによって、左右に隣り合う縦リブ２４の上端部の間や下端部の間が、上側連結板部２２や下側連結板部２０にて完全に閉鎖されている。そのため、自動車前部の下部部位への設置状態下で、空気取入口３９からエンジンルーム：Ｅ内に取り入れられた走行風や、脚払い装置１０の下部側を流れる走行風が、互いに隣り合う縦リブ２４の間に入り込んで、それらの走行風の流れが乱されたり、或いは遮られたりすることが有利に防止され得る。そして、その結果として、自動車下部での空力性能の向上が、より安定的に図られ得る。   In addition, in the leg washer 10, the longitudinal dimension of the upper connecting plate portion 22 is longer than the longitudinal dimension of the vertical ribs 24. Moreover, the lower connection board part 20 and the attachment board part 14 are comprised by the single member which consists of one board | plate material. Accordingly, the upper connecting plate portion 22 and the lower connecting plate portion 20 are completely closed between the upper end portions and the lower end portions of the vertical ribs 24 adjacent to the left and right. Therefore, the traveling wind taken into the engine room: E from the air intake port 39 and the traveling wind flowing through the lower side of the leg wiper 10 are installed adjacent to each other in the installed state in the lower part of the front part of the automobile. It can be advantageously prevented that they enter between the ribs 24 and disturb or obstruct their flow. As a result, the aerodynamic performance at the lower part of the automobile can be improved more stably.

なお、脚払い装置１０においては、補強部１８の前端に、左右方向に延びる前側壁部２６が設けられているが、脚払い装置１０の自動車への設置状態下で、かかる前側壁部２６は、フロントバンパ１２の内側に突入位置させられる。そのため、そのような前側壁部２６は、走行風に対して空力抵抗とならない。   In the leg cleaning device 10, a front side wall portion 26 extending in the left-right direction is provided at the front end of the reinforcing portion 18. However, when the leg cleaning device 10 is installed in an automobile, the front side wall portion 26 is The rush position is set inside the front bumper 12. Therefore, such front side wall part 26 does not become aerodynamic resistance with respect to traveling wind.

It is the same as that of the leg-pasting device 10. Accordingly, in the description of the leg cleaning device 54 of the present embodiment, the same reference numerals as those in FIGS. 1 to 4 are given to members and parts having the same structure as the leg cleaning device 10 according to the first embodiment. Therefore, the detailed description is omitted. The same applies to other embodiments shown in FIGS. 10 to 12 to be described later.

すなわち、図５から明らかなように、本実施形態の脚払い装置５４は、前記第一の実施形態に係る脚払い装置１０と同様な樹脂材料を用いて成形された、全体として、略長手矩形状を呈する樹脂成形品からなっている。そして、後側の略半分を占める後側部分が、横長矩形平板状の取付板部１４とされている一方、かかる取付板部１４を除いた前側部分が、補強部１８とされている。   That is, as is clear from FIG. 5, the leg cleaning device 54 of the present embodiment is formed using a resin material similar to that of the leg cleaning device 10 according to the first embodiment, and has a generally rectangular shape as a whole.

従って、本実施形態の脚払い装置５４は、前後方向に入力される衝撃荷重に対する剛性が、従来の脚払い装置の、リブ構造体からなる補強部や、複数の補強ビードと連結リブとを備えた補強部の剛性と略同等以上の大きさとされているのである。   Therefore, the leg cleaning device 54 of the present embodiment is provided with a reinforcing portion made of a rib structure, and a plurality of reinforcing beads and connecting ribs, which are rigid with respect to an impact load input in the front-rear direction. The size of the reinforcing part is approximately equal to or greater than the rigidity of the reinforcing part.

そして、かくの如き構造を有する脚払い装置５４も、前記第一の実施形態に係る脚払い装置１０と同様にして、自動車前部の下部部位に設置されるようになっている。   And the leg cleaning apparatus 54 which has such a structure is installed in the lower part of the front part of a motor vehicle similarly to the leg cleaning apparatus 10 which concerns on said 1st embodiment.

すなわち、例えば、図９に示されるように、フロントバンパ１２の下側突出部３８の内側に、補強部１８の前端部を突入させる一方、補強部１８の上側連結板部２２の後端面を、シュラウド４６やラジエータ４２の前面に対して僅かな距離を隔てて対向させた状態で、フロントバンパ１２とラジエータサポート４４との間に、前後方向に延びるように配置される。そして、取付板部１４において、ラジエータサポート４４の取付フランジ部５２，５２にボルト固定される。これによって、脚払い装置５４が、自動車前部の下部部位において、フロントバンパ１２の下側突出部３８とラジエータサポート４４との間に、複数の第一及び第二筒状構造体７４，７６を、衝撃荷重の入力方向となる前後方向に延びるように位置させた状態で、設置される。   That is, for example, as shown in FIG. 9, the front end portion of the reinforcing portion 18 is made to protrude inside the lower protruding portion 38 of the front bumper 12, while the rear end surface of the upper connecting plate portion 22 of the reinforcing portion 18 is The shroud 46 and the radiator 42 are disposed so as to extend in the front-rear direction between the front bumper 12 and the radiator support 44 while facing the front surfaces of the shroud 46 and the radiator 42 with a slight distance therebetween. Then, the mounting plate portion 14 is bolted to the mounting flange portions 52 and 52 of the radiator support 44. Accordingly, the leg washer 54 has a plurality of first and second tubular structures 74 and 76 between the lower protrusion 38 of the front bumper 12 and the radiator support 44 at the lower part of the front part of the automobile. It is installed in a state where it is positioned so as to extend in the front-rear direction, which is the input direction of the impact load.

かくして、本実施形態の脚払い装置５４にあっては、前記第一の実施形態に係る脚払い装置１０と同様に、自動車前部への設置状態下で、フロントバンパ１２に接触乃至は衝突した歩行者の脚部を払って（すくい上げて）、歩行者をボンネット４８等の衝撃吸収可能な部材側に転倒させ、以て、歩行者の保護及び安全を効果的に図ることが可能となっている。   Thus, in the leg cleaning device 54 of the present embodiment, as in the case of the leg cleaning device 10 according to the first embodiment, the front bumper 12 contacts or collides with the front bumper 12 in the installed state in the front part of the automobile. It is possible to effectively protect and protect the pedestrian by paying (scooping up) the leg of the pedestrian and causing the pedestrian to fall to the side of the hood 48 or the like that can absorb shocks. Yes.

そして、かかる脚払い装置５４では、特に、取付板部１４がラジエータサポート４４に固定された状態下で、補強部１８の下側連結板部２０に設けられた第一補強ビード５６の後側傾斜板部６８の後端が、ラジエータサポート４４の前側に設けられた取付フランジ部５２の前面に当接して、配置される。更に、上側連結板部２２に設けられた第二補強ビード７２の水平板部６０の後端面が、ラジエータサポート４４の前面に当接して、配置される。このことから明らかなように、本実施形態では、第一補強ビード５６の後側傾斜板部６８の後端部や第二補強ビード７２の水平板部６０の後端部にて、当接部が構成されている。   And in this leg-pasting device 54, the back side inclination of the 1st reinforcement bead 56 provided in the lower connection board part 20 of the reinforcement part 18 especially in the state in which the attachment board part 14 was fixed to the radiator support 44. The rear end of the plate portion 68 is disposed in contact with the front surface of the mounting flange portion 52 provided on the front side of the radiator support 44. Further, the rear end surface of the horizontal plate portion 60 of the second reinforcing bead 72 provided on the upper connecting plate portion 22 is disposed in contact with the front surface of the radiator support 44. As is clear from this, in the present embodiment, the abutting portion is formed at the rear end portion of the rear inclined plate portion 68 of the first reinforcing bead 56 or the rear end portion of the horizontal plate portion 60 of the second reinforcing bead 72. Is configured.

また、上記したように、複数の縦リブ２４の上端部同士或いは下端部同士を連結する部分が、縦断面コ字状乃至は台形状の第一補強ビード７０や第二補強ビード７２にて構成されている。   Further, as described above, the portion connecting the upper end portions or the lower end portions of the plurality of vertical ribs 24 is constituted by the first reinforcing bead 70 or the second reinforcing bead 72 having a U-shaped or trapezoidal cross section. Has been.

そうして、本実施形態の脚払い装置５４にあっては、前後方向に入力される衝撃荷重に対する剛性が、より有利に高められている。それ故、フロントバンパ１２に接触乃至は衝突した歩行者の脚部を、より確実に払って、歩行者の保護及び安全を更に一層効果的に図ることができるのである。   Thus, in the leg cleaning device 54 of the present embodiment, the rigidity with respect to the impact load input in the front-rear direction is increased more advantageously. Therefore, the leg part of the pedestrian that has contacted or collided with the front bumper 12 can be more reliably paid to further effectively protect and protect the pedestrian.

また、かかる脚払い装置５４では、上側連結板部２２に設けられる第一補強ビード７０の突出高さ：Ｈ2 や、下側連結板部２０に設けられる第二補強ビード５８の突出高さ：Ｈ1 が、従来の補強ビードの突出高さよりも十分に低くされて、それら第一及び第二補強ビード７０，５８の側方傾斜板部６６，６６の幅：Ｗ2 ，Ｗ1 が可及的に小さくされている。このため、第一補強ビード７０や第二補強ビード５８が、補強部１８に衝撃荷重が入力された際に、突出高さの大きな従来の第一及び第二補強ビードよりも変形し難い構造とされている。そして、それにより、補強部１８の剛性が更に効果的に高められ、以て、歩行者の保護を、より効果的に図り、また、歩行者の安全を更に有利に確保することが可能となっている。 Moreover, in this leg-pasting device 54, the protruding height of the first reinforcing bead 70 provided on the upper connecting plate portion 22: H 2 and the protruding height of the second reinforcing bead 58 provided on the lower connecting plate portion 20: H 1 is made sufficiently lower than the protruding height of the conventional reinforcing beads, and the widths W 2 and W 1 of the side inclined plate portions 66 and 66 of the first and second reinforcing beads 70 and 58 are possible. It is made small. Therefore, the first reinforcing bead 70 and the second reinforcing bead 58 have a structure that is less likely to be deformed than the conventional first and second reinforcing beads having a large protruding height when an impact load is input to the reinforcing portion 18. Has been. As a result, the rigidity of the reinforcing portion 18 is further effectively increased, and thus the pedestrian can be protected more effectively and the safety of the pedestrian can be more advantageously ensured. ing.

そして、本実施形態の脚払い装置５４においては、上側連結板部２２の上面からなる上側導風面３２が、エンジンルーム：Ｅ内の下部部位におけるフロントバンパ１２の後面（内面）からラジエータ４２の前面までの略全領域に亘って、水平方向に広がるように配置されている。また、下側連結板部２０の下面からなる下側導風面３０が、エンジンルーム：Ｅの外部において、水平方向に広がるように配置されている。   And in the leg wiping device 54 of the present embodiment, the upper air guide surface 32 formed from the upper surface of the upper connecting plate portion 22 is disposed from the rear surface (inner surface) of the front bumper 12 in the lower part of the engine room E to the radiator 42. It arrange | positions so that it may spread in a horizontal direction over substantially the whole area | region to a front surface. Further, the lower air guide surface 30 formed of the lower surface of the lower connecting plate portion 20 is arranged outside the engine room: E so as to spread in the horizontal direction.

従って、本実施形態の脚払い装置５４にあっても、前記第一の実施形態に係る脚払い装置１０と同様に、自動車前部の下部部位への設置状態下で、自動車前部の下部部位の空力抵抗を十分に低下させて、自動車下部の空力性能を効果的に高めることができ、それによって、燃費の向上を有利に達成できるのである。   Therefore, even in the leg wiper 54 according to the present embodiment, the lower part of the front part of the automobile is installed in the lower part of the front part of the automobile, similarly to the leg remover 10 according to the first embodiment. The aerodynamic resistance of the vehicle can be sufficiently reduced, and the aerodynamic performance of the lower part of the automobile can be effectively enhanced, thereby improving the fuel efficiency.

なお、本実施形態では、下側連結板部２０に対して、左右方向に延びる後側傾斜板部６８が設けられているが、これは、面積が十分に小さく、しかも後方に向かって下傾する形態を有しているため、走行風の流れを妨げるものとはならない。   In the present embodiment, the rear inclined plate portion 68 extending in the left-right direction is provided with respect to the lower connecting plate portion 20, but this is sufficiently small in area and inclined downward toward the rear. Therefore, it does not hinder the flow of traveling wind.

以上、本発明の具体的な構成について詳述してきたが、これはあくまでも例示に過ぎないのであって、本発明は、上記の記載によって、何等の制約をも受けるものではない。   The specific configuration of the present invention has been described in detail above. However, this is merely an example, and the present invention is not limited by the above description.

例えば、縦リブ２４の前後方向寸法や上側連結板部２２の前後方向寸法は、適宜に変更可能である。   For example, the longitudinal dimension of the vertical ribs 24 and the longitudinal dimension of the upper connecting plate portion 22 can be changed as appropriate.

すなわち、例えば、図１０に示されるように、縦リブ２４の前後方向寸法を、上側連結板部２２の前後方向寸法と同程度の大きさとしても良い。これによって、上側連結板部２２と下側連結板部２０とを、それらの前後方向寸法の全長に亘って延びる縦リブ２４にて相互に連結することが可能となる。その結果、補強部１８の剛性を、より効果的に高めることができる。   That is, for example, as shown in FIG. 10, the longitudinal dimension of the vertical ribs 24 may be the same as the longitudinal dimension of the upper connecting plate portion 22. Thereby, it becomes possible to mutually connect the upper side connection board part 22 and the lower side connection board part 20 with the vertical rib 24 extended over the full length of those front-back direction dimensions. As a result, the rigidity of the reinforcing portion 18 can be increased more effectively.

また、図１１に示されるように、縦リブ２４の前後方向寸法を下側連結板部２０の前後方向寸法よりも短くする一方、上側連結板部２２の前後方向寸法を、縦リブ２４の前後方向寸法と同程度の寸法としても良い。このような場合には、補強部１８の剛性を十分に確保しつつ、上側連結板部２２の前後方向寸法を短くした分だけ材料コストの削減が、有利に図られ得る。   Further, as shown in FIG. 11, the longitudinal dimension of the vertical rib 24 is made shorter than the longitudinal dimension of the lower connecting plate portion 20, while the longitudinal dimension of the upper connecting plate portion 22 is set to the longitudinal direction of the vertical rib 24. It is good also as a dimension comparable as a direction dimension. In such a case, the material cost can be advantageously reduced by the amount of shortening the front-rear direction dimension of the upper connecting plate portion 22 while sufficiently securing the rigidity of the reinforcing portion 18.

さらに、図１２に示されるように、縦リブ２４の前後方向寸法を上側連結板部２２の前後方向寸法よりも長くしても良い。この場合には、脚払い装置１０を自動車前部の下部部位に設置した状態下で、縦リブ２４の後端部を、例えば、ラジエータサポート４４の前面に当接させ得る程度の長さにおいて、縦リブ２４の前後方向寸法を設定することが望ましい。即ち、前記第一及び第二の実施形態とは異なり、上側連結板部２２の後端部に代えて、縦リブ２４の後端部を、当接部として構成しても良いのである。この場合には、上側連結板部２２の前後方向寸法を長くして、その後端部にて当接部を形成する場合よりも、脚払い装置１０の形成材料を有利に節約できる。   Furthermore, as shown in FIG. 12, the longitudinal dimension of the vertical rib 24 may be longer than the longitudinal dimension of the upper connecting plate portion 22. In this case, in a state where the rear end portion of the vertical rib 24 can be brought into contact with, for example, the front surface of the radiator support 44 in a state where the leg cleaning device 10 is installed in the lower part of the front portion of the automobile, It is desirable to set the longitudinal dimension of the vertical ribs 24. That is, unlike the first and second embodiments, the rear end portion of the vertical rib 24 may be configured as an abutting portion instead of the rear end portion of the upper connecting plate portion 22. In this case, the length of the upper connecting plate portion 22 in the front-rear direction can be increased, and the material for forming the leg fixing device 10 can be advantageously saved as compared with the case where the contact portion is formed at the rear end portion.

また、筒状構造体３４，７４，７６は、脚払い装置１０，５４の前側部分に、左右方向に並んで複数配置された状態で、前後方向に延びるように形成されるものであれば、その具体的な形状が、何等限定されるものではない。例えば、断面形状が、円形状、楕円形状、多角形状、無定形状とされたものが、筒状構造体３４，７４，７６として、適宜に採用される。更に、そのような筒状構造体３４，７４，７６の形成個数も、複数であれば、特に限定されるものではない。   Moreover, if the cylindrical structures 34, 74, and 76 are formed so as to extend in the front-rear direction in a state in which a plurality of the cylindrical structures 34, 74, and 76 are arranged side by side in the left-right direction, The specific shape is not limited at all. For example, those having a cross-sectional shape of a circular shape, an elliptical shape, a polygonal shape, or an indefinite shape are appropriately employed as the cylindrical structures 34, 74, and 76. Further, the number of the cylindrical structures 34, 74, 76 formed is not particularly limited as long as it is plural.

更にまた、平板形状を呈する上側連結板部２２の後端面を、取付板部１４が取り付けられるラジエータサポート４４等の車両部品に当接する当接部としても良い。   Furthermore, the rear end surface of the upper connecting plate portion 22 having a flat plate shape may be a contact portion that contacts a vehicle component such as the radiator support 44 to which the mounting plate portion 14 is attached.

なお、補強部１８に当接部を設ける場合には、脚払い装置１０，５４の自動車前部の下部部位への設置状態下で、当接部が、ラジエータサポート４４等の車両部品に必ずしも当接している必要はない。かかる当接部は、歩行者のフロントバンパ１２への衝突により生ずる衝撃荷重によって、補強部１８が変形する前、或いは補強部１８の変形の開始の初期段階で、補強部１８が後方に変位したときに、車両部品に当接するようになっておれば、当接部と車両部品との間に隙間が形成されていても良い。   When the abutting portion is provided on the reinforcing portion 18, the abutting portion does not necessarily contact a vehicle component such as the radiator support 44 under the installation state of the leg cleaning devices 10 and 54 in the lower part of the front portion of the automobile. There is no need to touch. Such a contact portion is displaced rearward by the impact load generated by the collision of the pedestrian with the front bumper 12 before the reinforcement portion 18 is deformed or at the initial stage of the deformation portion 18 being started. In some cases, a gap may be formed between the contact portion and the vehicle component as long as the contact is made with the vehicle component.

また、前記第二の実施形態に係る歩行者保護装置５４では、その前側部分に、縦断面八角形状の第一筒状構造体７４と、縦断面四角形状の第二筒状構造体７６とが、左右方向に交互に一つずつ並んで、それぞれ複数個ずつ設けられて、補強部１８が構成されていた。しかしながら、そのような第一筒状構造体７４と第二筒状構造体７６の並び順を適宜に変更して、補強部１８を構成することもできる。   Moreover, in the pedestrian protection apparatus 54 which concerns on said 2nd embodiment, the 1st cylindrical structure 74 of longitudinal cross-section octagon and the 2nd cylindrical structure 76 of longitudinal cross-section square are in the front part. The reinforcing portions 18 are configured by arranging one by one alternately in the left-right direction and providing a plurality of each. However, the reinforcing portion 18 can be configured by appropriately changing the arrangement order of the first cylindrical structure 74 and the second cylindrical structure 76.

さらに、上側連結板部２２と下側連結板部２０のうちの何れか一方を、縦断面コ字状を呈する屈曲板部としての第一及び第二補強ビード５６，５８，７０，７２が設けられた波形の板材にて構成する一方、それらのうちの何れか他方を、それら第一及び第二補強ビード５６，５８，７０，７２が何等設けられていない平板にて構成しても良い。   Furthermore, the 1st and 2nd reinforcement beads 56, 58, 70, 72 as a bending board part which exhibits any one of the upper side connection board part 22 and the lower side connection board part 20 in the longitudinal cross-section are provided. One of them may be constituted by a flat plate not provided with any of the first and second reinforcing beads 56, 58, 70, 72.

また、筒状構造体３４，７４，７６を、上下方向に、複数段、積み重ねた状態で、車幅方向に、複数個、並べて配置して、補強部１８を形成することも可能である。   It is also possible to form the reinforcing portion 18 by arranging a plurality of cylindrical structures 34, 74, and 76 in the vehicle width direction in a stacked state in a plurality of stages in the vertical direction.

加えて、本発明は、自動車の前面に取り付けられたフロントバンパの内側に設置される歩行者保護装置の他、フロントバンパの内側以外に設置されるものや、自動車以外の車両の前部の下部部位に様々な形態で設置される歩行者保護装置の何れに対しても有利に適用され得ることは、勿論である。   In addition, the present invention includes a pedestrian protection device installed inside a front bumper attached to the front surface of an automobile, a device installed outside the front bumper, and a lower part of a front part of a vehicle other than an automobile. Of course, it can be advantageously applied to any of the pedestrian protection devices installed in various forms on the site.

その他、一々列挙はしないが、本発明は、当業者の知識に基づいて種々なる変更、修正、改良等を加えた態様において実施され得るものであり、また、そのような実施態様が、本発明の趣旨を逸脱しない限り、何れも、本発明の範囲内に含まれるものであることは、言うまでもないところである。   In addition, although not enumerated one by one, the present invention can be carried out in a mode to which various changes, modifications, improvements, etc. are added based on the knowledge of those skilled in the art. It goes without saying that all are included in the scope of the present invention without departing from the spirit of the present invention.
