Abstract

Provided is a retraction prevention device for a vehicular pedal device with which, when the dash panel is displaced toward the rear side of the vehicle, a deformation of a vehicle body-side member toward the rear side of the vehicle can be inhibited, and an operation pedal can be prevented from retracting. A brake pedal device 1 has a pedal bracket 10, an operation pedal 20, an intermediate lever 25, a coupling link 30, a retraction prevention link 40, and a retraction prevention member 50. A second support shaft 12, which couples the retraction prevention link 40 to the retraction prevention member 50, is positioned below a reference line L, and therefore the brake pedal device 1 moves the second support shaft 12 downward when the vehicle experiences a front collision. As a result, the intermediate lever 25 moves downward together with the second support shaft 12, such that the operation pedal 20 turns, via the coupling link 30, around a first support shaft 11 toward the front side of the vehicle. The load from the front side of the vehicle acts in the direction moving the second support shaft 12 downward, such that deformations to members such as an instrument panel reinforcement I can be inhibited.

　従来、車両の前方衝突時に操作ペダルが車体後方の乗員側に移動することを抑制する車両用ペダル装置の後退防止装置として、例えば、特許文献１、特許文献２記載の発明が知られている。特許文献１、特許文献２記載のブレーキペダル後退防止装置は、ペダルブラケットと、ブレーキペダルと、中間レバーと、連結部材を有する車両用ペダル装置に関し、ダッシュパネルが運転席側へ後退変位させられた際に前記操作ペダルの踏部がその運転席側へ後退することを抑制するように構成されている。 Conventionally, for example, the inventions described in Patent Literature 1 and Patent Literature 2 are known as a back-prevention device for a vehicle pedal device that suppresses the operation pedal from moving to the occupant side behind the vehicle body at the time of a forward collision of the vehicle. The brake pedal retraction preventing device described in Patent Literature 1 and Patent Literature 2 relates to a vehicle pedal device having a pedal bracket, a brake pedal, an intermediate lever, and a connecting member, and the dash panel is displaced backward toward the driver's seat. In this case, the step portion of the operation pedal is configured to be prevented from moving backward to the driver's seat side.
　具体的に説明すると、特許文献１記載のブレーキペダル装置は、ダッシュパネルが後退変位させられると、車両後方側の車体側部材としてのステアリングメンバ及び衝突用インパクトブラケットに、中間レバーに相当する回動レバーを接触させて、当該回動レバーを回動させるように構成されている。そして、特許文献１記載のブレーキペダル装置は、車体側部材との当接による回動レバーの回動に伴って、ペダルアームを車両前方側に回動させて、ブレーキペダルの後退を抑制している。 More specifically, in the brake pedal device described in Patent Document 1, when the dash panel is moved backward, the steering member as a vehicle body side member on the rear side of the vehicle and the impact impact bracket are rotated corresponding to the intermediate lever. The rotating lever is rotated by contacting the lever. And the brake pedal apparatus of patent document 1 suppresses retraction of a brake pedal by rotating a pedal arm to the vehicle front side with rotation of the rotation lever by contact | abutting with a vehicle body side member. Yes.
　又、特許文献２記載の車両用ペダル支持構造においても、ダッシュパネルが後退変位させられた場合、車両後方側の車体側部材としてのインパネリインフォース及びサブペダルブラケットに、中間レバーに相当する第１リンクを接触させて、当該第１リンクを回動させるように構成されている。そして、特許文献２記載の車両用ペダル支持構造においても、車体側部材との当接に基づく第１リンクの回動に伴って、ペダルアームを車両前方側に回動させて、ブレーキペダルの後退を抑制している。 Further, in the vehicle pedal support structure described in Patent Document 2, when the dash panel is moved backward, the instrument panel reinforcement as the vehicle body side member on the rear side of the vehicle and the sub pedal bracket are connected to the first link corresponding to the intermediate lever. And the first link is rotated.

　ここで、近年においては、車両における広い車室スペースの確保が重要視されており、ダッシュパネルの前方部分（例えば、エンジンルーム）と、車体側部材（例えば、インパネリインフォース）との間隔が狭まる傾向にある。 Here, in recent years, securing a large cabin space in a vehicle has been regarded as important, and the distance between a front portion (for example, an engine room) of a dash panel and a vehicle body side member (for example, instrument panel reinforcement) tends to be narrowed. It is in.
　特許文献１、２記載の発明のように、操作ペダルの後退防止を実現する上で、中間レバーと車体側部材との接触を条件とする場合、ダッシュパネルの前方部分（例えば、エンジンルーム）と、車体側部材（例えば、インパネリインフォース）との間隔が狭まると、適正な状態で操作ペダルの後退防止機能を実現できない場合が生じ得る。 As in the inventions described in Patent Documents 1 and 2, in order to prevent the operation pedal from retreating, when the contact between the intermediate lever and the vehicle body side member is a condition, If the distance from the vehicle body side member (for example, instrument panel reinforcement) is narrowed, there may be a case where the function of preventing the operation pedal from retreating cannot be realized in an appropriate state.
　又、中間レバーが車体側部材と接触する関係上、前方衝突等に伴う大荷重が、中間レバー等を介して車体側部材に作用し、車体側部材を車両後方側へ変形させてしまう可能性がある。一般的に、車体側部材には、車両のステアリング等が配設されている為、車体側部材が後方側へ変形してしまった場合、乗員（例えば、運転者の上半身）を負傷させてしまう虞があった。 In addition, since the intermediate lever comes into contact with the vehicle body side member, there is a possibility that a large load due to a frontal collision or the like acts on the vehicle body side member via the intermediate lever or the like, causing the vehicle body side member to be deformed to the vehicle rear side. There is. In general, since the vehicle body side member is provided with a vehicle steering or the like, if the vehicle body side member is deformed rearward, an occupant (for example, a driver's upper body) is injured. There was a fear.
　本発明は、車両の前方衝突に伴ってダッシュパネルが車両後側へ変位した場合に、操作ペダルが後退することを抑制する車両用ペダル装置の後退防止装置に関し、車両後方側への車体側部材の変形を防止すると共に、操作ペダルの後退を抑制可能な車両用ペダル装置の後退防止装置を提供する。 The present invention relates to a reverse prevention device for a vehicle pedal device that suppresses the operation pedal from moving backward when a dash panel is displaced to the vehicle rear side due to a frontal collision of the vehicle, and relates to a vehicle body side member toward the vehicle rear side. An apparatus for preventing the backward movement of a pedal device for a vehicle that can prevent the deformation of the operational pedal and suppress the backward movement of an operation pedal is provided.
　本発明の一側面に係る車両用ペダル装置の後退防止装置は、車両前側のダッシュパネルに固定されたペダルブラケットと、前記ペダルブラケットの第１支持軸によって回動可能に配設され、車両前側への踏込み操作に用いられる踏部を有する操作ペダルと、前記第１支持軸よりも車両後方側において、当該第１支持軸に平行に設けられた第２支持軸まわりに回動可能に支持されると共に、前記第２支持軸を軸とした出力方向への回動によって、所定の出力部材を車両前側へ変位させる中間レバーと、前記操作ペダルと前記中間レバーを連結し、前記操作ペダルに対する踏込み操作に連動して、前記中間レバーを前記出力方向へ回動させる連結リンクと、を有する車両用ペダル装置に関し、前記ダッシュパネルが車両後側へ変位した場合に、前記操作ペダルの踏部の車両後側への変位を抑制する後退防止装置であって、前記ペダルブラケットに対して一端部が回動可能に取り付けられると共に、前記第２支持軸を中心として回動可能に支持された第１後退防止部材と、車両後方側に位置する車体側部材に対して一端部が取り付けられると共に、前記第１後退防止部材に対して回動可能に連結された第２後退防止部材と、を有し、前記第１後退防止部材と前記第２後退防止部材を回動可能に連結した連結位置は、前記ペダルブラケットに対して前記第１後退防止部材が取り付けられている第１取付位置と、前記車体側部材に対して前記第２後退防止部材が取り付けられている第２取付位置とを結ぶ基準線よりも下方に位置していることを特徴とする。 According to an aspect of the present invention, there is provided a vehicular pedal apparatus for preventing a backward movement of a pedal bracket, which is rotatably disposed by a pedal bracket fixed to a dash panel on the front side of the vehicle and a first support shaft of the pedal bracket. An operation pedal having a step portion used for stepping on the vehicle and a second support shaft provided in parallel with the first support shaft on the vehicle rear side of the first support shaft so as to be rotatable. And an intermediate lever for displacing a predetermined output member toward the front of the vehicle by turning in the output direction about the second support shaft, and the stepping operation on the operation pedal by connecting the operation pedal and the intermediate lever. In connection with the vehicle pedal device having a connecting link for rotating the intermediate lever in the output direction, when the dash panel is displaced to the vehicle rear side, An anti-retraction device that suppresses displacement of the stepped portion of the operation pedal toward the rear side of the vehicle, wherein one end portion is rotatably attached to the pedal bracket and is rotated about the second support shaft. One end part is attached to the first retreat preventing member supported so as to be able to support the vehicle body side member located on the rear side of the vehicle, and the second retreat is pivotally connected to the first retraction preventing member. A connecting position where the first retraction preventing member and the second retraction preventing member are pivotably connected to each other. The first retraction preventing member is attached to the pedal bracket. It is located below the reference line connecting 1 attachment position and the 2nd attachment position where the 2nd retreat prevention member is attached to the body side member.
当該車両用ペダル装置の後退防止装置は、ペダルブラケットと、操作ペダルと、中間レバーと、連結リンクと、を有している。そして、当該車両用ペダル装置の後退防止装置は、踏込み操作に伴う操作ペダルの回動に連動して、連結リンクを介して中間レバーを回動させることができ、結果的に、出力部材を車両前側へ変位させ得る。ここで、当該車両用ペダル装置の後退防止装置は、更に、第１後退防止部材と、第２後退防止部材とを有しており、前記第１後退防止部材と前記第２後退防止部材の連結位置は、第１取付位置と第２取付位置とを結ぶ基準線よりも下方に位置している。これにより、当該車両用ペダル装置の後退防止装置は、前記ダッシュパネルが車両後側へ変位し、ダッシュパネルと車体側部材との間隔が狭まっていくと、前記第１後退防止部材と第２後退防止部材の連結位置を下方へ移動させることができる。ここで、第１後退防止部材は、前記第２支持軸を中心として回動可能に支持されている為、連結位置が下方に移動することに伴い、第２支持軸も下方に移動していき、ペダルブラケットの第１支持軸よりも下方へ移動していく。この結果、中間レバーも第２支持軸と共に下方に移動する為、操作ペダルは、連結部材を介して、第１支持軸を中心として車両前方側へ回動することになる。

The connection position of the prevention member can be moved downward. Here, since the first retraction preventing member is supported so as to be rotatable about the second support shaft, the second support shaft also moves downward as the connecting position moves downward. The pedal bracket moves downward from the first support shaft. As a result, since the intermediate lever also moves downward together with the second support shaft, the operation pedal rotates to the front side of the vehicle about the first support shaft via the connecting member.
In other words, the reverse preventing device for the vehicle pedal device includes a first reverse preventing member and a second reverse preventing member, and the connection position of the first reverse preventing member and the second reverse preventing member is set to the first position. It is located below the reference line connecting the attachment position and the second attachment position.

（第１実施形態）
　以下、本発明に係る車両用ペダル装置の後退防止装置を、常用ブレーキ用のブレーキペダル装置１に適用した実施形態（第１実施形態）について、図面を参照しつつ詳細に説明する。 (First embodiment)
Hereinafter, an embodiment (first embodiment) in which a vehicle pedal device reverse prevention device according to the present invention is applied to a brake pedal device 1 for a service brake will be described in detail with reference to the drawings.
（ブレーキペダル装置の概略構成）
　先ず、第１実施形態に係るブレーキペダル装置１の概略構成について、図１～図４を参照しつつ詳細に説明する。尚、図１は、ブレーキペダル装置１の概略構成を示す側面図であり、ペダルブラケット１０を仮想線（破線）で示すことで、その内側の構造が分かるように示している。 (Schematic configuration of brake pedal device)
First, a schematic configuration of the brake pedal device 1 according to the first embodiment will be described in detail with reference to FIGS. 1 to 4. FIG. 1 is a side view showing a schematic configuration of the brake pedal device 1, and the pedal bracket 10 is shown by an imaginary line (broken line) so that the inner structure thereof can be understood.
　第１実施形態に係るブレーキペダル装置１は、エンジンルームと車室内とを区切るダッシュパネルＰに対して固設されており、ペダルブラケット１０と、操作ペダル２０と、中間レバー２５と、連結リンク３０と、後退防止用リンク４０と、後退防止部材５０とを有している。当該ブレーキペダル装置１は、操作ペダル２０の踏込み操作によって当該操作ペダル２０が回動した場合に、ブレーキブースタＢのオペレーティングロッドＲを車両前方側へ変位させることで、車両に対する制動力を発生させるように構成されている。 The brake pedal device 1 according to the first embodiment is fixed to a dash panel P that divides the engine room and the vehicle interior, and includes a pedal bracket 10, an operation pedal 20, an intermediate lever 25, and a connection link 30. And a reverse prevention link 40 and a reverse prevention member 50. The brake pedal device 1 generates a braking force on the vehicle by displacing the operating rod R of the brake booster B toward the front side of the vehicle when the operation pedal 20 is rotated by a depression operation of the operation pedal 20. It is configured.
　ブレーキブースタＢは、ダッシュパネルＰの車両前側（即ち、エンジンルーム側）に一体的に固設されており、出力部材としてのオペレーティングロッドＲを有している。当該ブレーキブースタＢは、オペレーティングロッドＲが車両前側へ変位した場合に、操作ペダル２０を介して伝達された制動力を倍化して、倍化した制動力を車両に伝達する。そして、オペレーティングロッドＲは、ダッシュパネルＰから車両後側の車室内へ突き出すように配設されており、車両前後方向へ変位可能に構成されている。 The brake booster B is integrally fixed to the front side of the dash panel P (that is, the engine room side), and has an operating rod R as an output member. When the operating rod R is displaced toward the vehicle front side, the brake booster B doubles the braking force transmitted through the operation pedal 20 and transmits the doubled braking force to the vehicle. The operating rod R is disposed so as to protrude from the dash panel P into the vehicle interior on the vehicle rear side, and is configured to be displaceable in the vehicle front-rear direction.
　図１に示すように、インパネリインフォースメントＩは、ダッシュパネルＰよりも車両後側（運転席側）に配設されており、本発明における車体側部材を構成する。そして、インパネリインフォースメントＩは、高強度及び高剛性を有するパイプ状の部材であり、車両幅方向を長手方向として配置されている。インパネリインフォースメントＩは、一般に、衝突時等の車両前方からの大荷重入力時に車両後側へ変位する可能性や変形量がダッシュパネルＰよりも少ない。又、当該インパネリインフォースメントＩには、車両の操舵装置であるステアリングを構成するステアリングシャフト（図示せず）が、ダッシュパネルＰの車両前側から車室内に向かって伸びるように固設されている。尚、図１に示すように、インパネリインフォースメントＩには、後述するスライドブラケット６０が固設されており、本発明の車体側部材の一部を構成する。当該スライドブラケット６０の詳細については、後に図面を参照しつつ説明する。 As shown in FIG. 1, the instrument panel reinforcement I is disposed on the vehicle rear side (driver's seat side) with respect to the dash panel P, and constitutes a vehicle body side member in the present invention. The instrument panel reinforcement I is a pipe-like member having high strength and high rigidity, and is arranged with the vehicle width direction as the longitudinal direction. The instrument panel reinforcement I is generally less likely than the dash panel P to be displaced toward the rear of the vehicle when a heavy load is input from the front of the vehicle, such as during a collision. In addition, a steering shaft (not shown) that constitutes a steering that is a vehicle steering device is fixed to the instrument panel reinforcement I so as to extend from the front side of the dash panel P toward the vehicle interior. As shown in FIG. 1, a slide bracket 60 described later is fixed to the instrument panel reinforcement I, and constitutes a part of the vehicle body side member of the present invention. Details of the slide bracket 60 will be described later with reference to the drawings.
　ペダルブラケット１０は、ダッシュパネルＰの車室側に対して、ボルト等を用いて固定されており、車幅方向に間隔をおいて対向する一対の側板を有している。第１実施形態に係るペダルブラケット１０は、第１支持軸１１を有している。 The pedal bracket 10 is fixed to the passenger compartment side of the dash panel P using bolts or the like, and has a pair of side plates facing each other with a gap in the vehicle width direction. The pedal bracket 10 according to the first embodiment has a first support shaft 11.
　第１支持軸１１は、ペダルブラケット１０における一対の側板の間に亘って、略水平で且つ車幅方向と略平行に延びるように、ペダルブラケット１０に配設されている。第１実施形態においては、第１支持軸１１は、ペダルブラケット１０に対して、操作ペダル２０の上部を回動自在に支持すると共に、後述する後退防止用リンク４０の一端部をペダルブラケット１０に対して回動可能に取り付ける機能を果たしている。従って、第１実施形態において、第１支持軸１１の位置は、本発明における第１取付位置として機能する。 The first support shaft 11 is disposed on the pedal bracket 10 so as to extend between the pair of side plates of the pedal bracket 10 so as to be substantially horizontal and substantially parallel to the vehicle width direction. In the first embodiment, the first support shaft 11 rotatably supports the upper portion of the operation pedal 20 with respect to the pedal bracket 10, and one end portion of a retraction preventing link 40 described later on the pedal bracket 10. It fulfills the function of being attached to be rotatable. Therefore, in the first embodiment, the position of the first support shaft 11 functions as the first mounting position in the present invention.
　そして、第２支持軸１２は、第１支持軸１１よりも車両後側において、第１支持軸１１と平行に伸びるように配設されている。当該第２支持軸１２は、オペレーティングロッドＲが接続された中間レバー２５の下部を回動可能に支持すると共に、後述する後退防止用リンク４０の他端部を回動可能に支持している。更に、第１実施形態に係る第２支持軸１２は、後述する後退防止部材５０の端部を回動可能に支持しており、後退防止用リンク４０及び後退防止部材５０を相互に回動可能に連結している。従って、第１実施形態においては、第２支持軸１２の位置は、本発明における連結位置として機能する。 The second support shaft 12 is disposed on the rear side of the vehicle with respect to the first support shaft 11 so as to extend in parallel with the first support shaft 11. The second support shaft 12 rotatably supports the lower portion of the intermediate lever 25 to which the operating rod R is connected, and rotatably supports the other end portion of a reverse preventing link 40 described later. Further, the second support shaft 12 according to the first embodiment rotatably supports an end portion of a backward movement preventing member 50, which will be described later, and the backward movement prevention link 40 and the backward movement prevention member 50 can be rotated relative to each other. It is linked to. Therefore, in the first embodiment, the position of the second support shaft 12 functions as a connection position in the present invention.
　操作ペダル２０は、ペダルブラケット１０の第１支持軸１１によって、その上部を回動可能に支持されており、下端部に踏部２１を有している。従って、操作ペダル２０は、踏部２１を利用して踏込み操作が行われた場合、第１支持軸１１を中心に回動する。この時、踏部２１は、車両前側に向かって移動する。 The operation pedal 20 is rotatably supported by the first support shaft 11 of the pedal bracket 10 and has a step portion 21 at the lower end. Therefore, the operation pedal 20 rotates around the first support shaft 11 when a stepping operation is performed using the step portion 21. At this time, the step portion 21 moves toward the front side of the vehicle.
　そして、中間レバー２５は、第１支持軸１１に対して車両後方側に配置された第２支持軸１２によって、その下端部を回動可能に支持されており、上方に向かって延びている。中間レバー２５の上端部には、オペレーティングロッドＲが、クレビスを介して連結されている。従って、中間レバー２５が第２支持軸１２を中心として回動することによって、オペレーティングロッドＲは、車両前後方向へ変位し得る。つまり、当該ブレーキペダル装置１によれば、中間レバー２５によって、オペレーティングロッドＲを車両前側へ押圧することで、ブレーキブースタＢを介して制動力を発生させ得る。 The lower end of the intermediate lever 25 is rotatably supported by the second support shaft 12 disposed on the vehicle rear side with respect to the first support shaft 11, and extends upward. An operating rod R is connected to the upper end of the intermediate lever 25 via a clevis. Therefore, when the intermediate lever 25 rotates around the second support shaft 12, the operating rod R can be displaced in the vehicle front-rear direction. That is, according to the brake pedal device 1, the braking force can be generated via the brake booster B by pressing the operating rod R toward the vehicle front side by the intermediate lever 25.
　連結リンク３０は、操作ペダル２０の上方後側部分と、中間レバー２５の下方前側部分を連結しており、操作ペダル２０及び中間レバー２５に対して回動可能に取り付けられている。連結リンク３０の一端側は、操作ペダル２０の上方後側部分に対して、連結ピン３１を介して連結されている為、連結リンク３０は、連結ピン３１を中心として、操作ペダル２０に対して回動し得る。又、連結リンク３０の他端側は、中間レバー２５の下方前側部分に対して、連結ピン３２を介して連結されている為、連結リンク３０は、連結ピン３２を中心として、中間レバー２５に対して回動し得る。従って、当該ブレーキペダル装置１においては、第１支持軸１１を中心とした操作ペダル２０の回動を、連結リンク３０を介して、中間レバー２５に伝達することができ、中間レバー２５を、第２支持軸１２を中心として回動させることができる。 The connection link 30 connects the upper rear portion of the operation pedal 20 and the lower front portion of the intermediate lever 25, and is attached to the operation pedal 20 and the intermediate lever 25 so as to be rotatable. Since one end side of the connection link 30 is connected to the upper rear side portion of the operation pedal 20 via the connection pin 31, the connection link 30 is connected to the operation pedal 20 around the connection pin 31. Can rotate. Further, since the other end side of the connection link 30 is connected to the lower front side portion of the intermediate lever 25 via the connection pin 32, the connection link 30 is connected to the intermediate lever 25 around the connection pin 32. It can rotate with respect to it. Therefore, in the brake pedal device 1, the rotation of the operation pedal 20 around the first support shaft 11 can be transmitted to the intermediate lever 25 via the connection link 30. 2 It can be rotated around the support shaft 12.
　後退防止用リンク４０は、図１に示すように、ペダルブラケット１０の各側板に沿って配置された鋼板製の部材である。後退防止用リンク４０における車両前方側の端部は、第１支持軸１１によって支持されており、後退防止用リンク４０における車両後方側の端部は、第２支持軸１２によって支持されている。ここで、第１支持軸１１は、ペダルブラケット１０に配設される一方で、第２支持軸１２は、ペダルブラケット１０を介さずに配設されている。従って、後退防止用リンク４０は、第２支持軸１２の移動に伴い、第１支持軸１１まわりに回動し得る。そして、当該後退防止用リンク４０は、本発明における第１後退防止部材の一例であり、第１支持軸１１と第２支持軸１２の相対的な位置関係（距離）を一定に保つ機能を果たしている。 As shown in FIG. 1, the reverse prevention link 40 is a steel plate member disposed along each side plate of the pedal bracket 10. An end portion on the vehicle front side of the reverse travel prevention link 40 is supported by the first support shaft 11, and an end portion on the vehicle rear side of the reverse travel prevention link 40 is supported by the second support shaft 12. Here, the first support shaft 11 is disposed on the pedal bracket 10, while the second support shaft 12 is disposed without the pedal bracket 10. Accordingly, the retraction preventing link 40 can rotate around the first support shaft 11 as the second support shaft 12 moves. The retraction preventing link 40 is an example of a first retraction preventing member in the present invention, and fulfills a function of keeping the relative positional relationship (distance) between the first support shaft 11 and the second support shaft 12 constant. Yes.
　そして、後退防止部材５０は、ブレーキペダル装置１の後方部分を構成し、断面略コ字状に形成されている。図１に示すように、第１実施形態に係る後退防止部材５０は、その一端部が車体側部材を構成するスライドブラケット６０に対して取り付けられる。又、当該後退防止部材５０は、第２支持軸１２を介して、後退防止用リンク４０に対して回動可能に連結されている。そして、当該後退防止部材５０は、本発明における第２後退防止部材の一例であり、車両の前方衝突等により前方から荷重が加わった場合には、車体側部材を構成するスライドブラケット６０から離脱するように取り付けられている。 The retraction preventing member 50 constitutes a rear portion of the brake pedal device 1 and has a substantially U-shaped cross section. As shown in FIG. 1, the retreat prevention member 50 according to the first embodiment is attached to a slide bracket 60 whose one end constitutes a vehicle body side member. The retraction preventing member 50 is connected to the retraction preventing link 40 via the second support shaft 12 so as to be rotatable. The reverse preventing member 50 is an example of a second reverse preventing member according to the present invention, and is detached from the slide bracket 60 constituting the vehicle body side member when a load is applied from the front due to a forward collision of the vehicle. It is attached as follows.
　上述したように、スライドブラケット６０は、車体側部材を構成するインパネリインフォースメントＩに対して固設されており、所定の高剛性を有している。当該スライドブラケット６０は、断面略コ字状に形成されており、前記後退防止部材５０が離脱可能に取り付けられる取付面にスリット６１を有している。スライドブラケット６０の取付面は、車両後方側ほど下方へ向かうように傾斜している。 As described above, the slide bracket 60 is fixed to the instrument panel reinforcement I constituting the vehicle body side member, and has a predetermined high rigidity. The slide bracket 60 has a substantially U-shaped cross section, and has a slit 61 on a mounting surface to which the retraction preventing member 50 is detachably attached. The mounting surface of the slide bracket 60 is inclined downward toward the rear side of the vehicle.
　ここで、スライドブラケット６０に対する後退防止部材５０の離脱構造について、図２を参照しつつ説明する。図２に示すように、スライドブラケット６０の取付面には、スリット６１が形成されている。スリット６１は、所定幅をもって車両の前後方向に沿って伸びて形成されており、後端部に幅広部６２を有している。一方、スライドブラケット６０の取付面に対向する後退防止部材５０の一面には、固定ボルト５１及びナット５２が配設されている。 Here, the detachment structure of the receding prevention member 50 with respect to the slide bracket 60 will be described with reference to FIG. As shown in FIG. 2, a slit 61 is formed on the mounting surface of the slide bracket 60. The slit 61 is formed to extend along the front-rear direction of the vehicle with a predetermined width, and has a wide portion 62 at the rear end. On the other hand, a fixing bolt 51 and a nut 52 are disposed on one surface of the receding prevention member 50 facing the mounting surface of the slide bracket 60.
　ここで、スリット６１の幅寸法は、固定ボルト５１の軸径よりも若干大きく且つ固定ボルト５１における頭部の外径よりも小さく形成されている。従って、固定ボルト５１をスリット６１に挿通させてナット５２と螺合させることにより、後退防止部材５０を、車体側部材を構成するスライドブラケット６０に対して取り付けることができる。 Here, the width dimension of the slit 61 is slightly larger than the shaft diameter of the fixing bolt 51 and smaller than the outer diameter of the head of the fixing bolt 51. Therefore, the retraction preventing member 50 can be attached to the slide bracket 60 constituting the vehicle body side member by inserting the fixing bolt 51 through the slit 61 and screwing it with the nut 52.
　そして、スリット６１における幅広部６２の開口寸法は、固定ボルト５１における頭部の外径よりも大きく形成されている。従って、スライドブラケット６０に対して後退防止部材５０が相対移動して、固定ボルト５１がスリット６１における幅広部６２に到達すると、固定ボルト５１及びナット５２は、スリット６１の幅広部６２から脱落し得る。 And the opening dimension of the wide part 62 in the slit 61 is formed larger than the outer diameter of the head in the fixing bolt 51. Accordingly, when the receding prevention member 50 moves relative to the slide bracket 60 and the fixing bolt 51 reaches the wide portion 62 in the slit 61, the fixing bolt 51 and the nut 52 can fall off from the wide portion 62 of the slit 61. .
　即ち、固定ボルト５１及びナット５２がスリット６１における幅広部６２を除いた部分に位置している場合には、後退防止部材５０は、車体側部材を構成するスライドブラケット６０に取り付けられた状態を維持する。一方、後退防止部材５０が車両後方側へ変位することにより、固定ボルト５１及びナット５２が相対的に幅広部６２に位置すると、後退防止部材５０は、スライドブラケット６０から離脱することになる。従って、第１実施形態においては、スリット６１を挿通した固定ボルト５１及びナット５２の位置が、本発明における第２取付位置として機能する。 That is, when the fixing bolt 51 and the nut 52 are located in a portion of the slit 61 excluding the wide portion 62, the retraction preventing member 50 is maintained attached to the slide bracket 60 constituting the vehicle body side member. To do. On the other hand, when the locking member 51 and the nut 52 are positioned at the relatively wide portion 62 due to the displacement of the backward movement prevention member 50 toward the vehicle rear side, the backward movement prevention member 50 is detached from the slide bracket 60. Therefore, in the first embodiment, the positions of the fixing bolt 51 and the nut 52 inserted through the slit 61 function as the second mounting position in the present invention.
　以上のように構成することで、第１実施形態に係るブレーキペダル装置１においては、図１に示すように、本発明における第２取付位置として機能する固定ボルト５１及びナット５２の位置は、本発明における第１取付位置として機能する第１支持軸１１よりも上方に位置する。そして、第１取付位置と第２取付位置を結ぶ基準線Ｌは、車両後方側に向かうほど上方となるように傾斜している。そして、第１実施形態に係るブレーキペダル装置１では、本発明における連結位置として機能する第２支持軸１２は、第１取付位置と第２取付位置を結ぶ基準線Ｌよりも下方に位置することになる。 With the configuration as described above, in the brake pedal device 1 according to the first embodiment, as shown in FIG. 1, the positions of the fixing bolt 51 and the nut 52 functioning as the second attachment position in the present invention are It is located above the first support shaft 11 that functions as the first mounting position in the invention. And the reference line L which connects a 1st attachment position and a 2nd attachment position inclines so that it may become upward, so that it goes to the vehicle rear side. And in the brake pedal apparatus 1 which concerns on 1st Embodiment, the 2nd support shaft 12 which functions as a connection position in this invention is located below the reference line L which ties a 1st attachment position and a 2nd attachment position. become.
（操作ペダルの踏込み操作に伴う各部の動作）
　次に、上述したブレーキペダル装置１において、操作ペダル２０の踏込み操作が行われた場合の各部の動きについて説明する。 (Operation of each part in response to depressing operation pedal)
Next, the movement of each part when the operation pedal 20 is depressed in the brake pedal device 1 described above will be described.
　操作ペダル２０に対して踏込み操作が行われた場合、踏部２１が車両前側へ踏み込まれることになる。この為、操作ペダル２０は、第１支持軸１１を中心として回動する。この時、操作ペダル２０の上部は、第１支持軸１１を中心として車両下方へ向かって回動する為、操作ペダル２０の回動は、連結リンク３０を介して、中間レバー２５に対して伝達される。 When the operation pedal 20 is depressed, the step portion 21 is depressed toward the front of the vehicle. For this reason, the operation pedal 20 rotates around the first support shaft 11. At this time, since the upper part of the operation pedal 20 rotates about the first support shaft 11 toward the lower side of the vehicle, the rotation of the operation pedal 20 is transmitted to the intermediate lever 25 via the connection link 30. Is done.
　上述したように、連結リンク３０は、中間レバー２５の下方前側部分に対して、連結ピン３２を介して連結されている。この為、中間レバー２５は、操作ペダル２０の回動に伴って、第２支持軸１２を中心として回動し、中間レバー２５の上部を車両前側に向かって移動させ得る。中間レバー２５の上部には、ブレーキブースタＢのオペレーティングロッドＲが、クレビスを介して連結されている。この結果、当該ブレーキペダル装置１は、操作ペダル２０の踏込み操作に連動して、オペレーティングロッドＲを出力方向（車両前側）へ押圧することができ、車両に対する制動力を発生させ得る。 As described above, the connecting link 30 is connected to the lower front portion of the intermediate lever 25 via the connecting pin 32. Therefore, the intermediate lever 25 can rotate about the second support shaft 12 as the operation pedal 20 rotates, and can move the upper portion of the intermediate lever 25 toward the front side of the vehicle. The operating rod R of the brake booster B is connected to the upper part of the intermediate lever 25 via a clevis. As a result, the brake pedal device 1 can press the operating rod R in the output direction (the vehicle front side) in conjunction with the stepping operation of the operation pedal 20, and can generate a braking force on the vehicle.
(前方衝突時におけるブレーキペダル装置の動作)
　次に、車両の前方衝突時におけるブレーキペダル装置１の動作について、図３、図４を参照しつつ詳細に説明する。車両の前方衝突等によって車両前側から大荷重が入力された場合、ダッシュパネルＰは、入力された大荷重によって車両後側へ変位する。一方、インパネリインフォースメントＩは、車両前側から大荷重が入力された場合であっても、車両後側への変位量は少ない。従って、車両前側から入力された大荷重によるダッシュパネルＰとインパネリインフォースメントＩとの変位差によって、ペダルブラケット１０は、ダッシュパネルＰと共に、相対的に車両後側へ移動する。 (Brake pedal operation during forward collision)
Next, the operation of the brake pedal device 1 at the time of a frontal collision of the vehicle will be described in detail with reference to FIGS. When a large load is input from the front side of the vehicle due to a frontal collision of the vehicle or the like, the dash panel P is displaced to the rear side of the vehicle due to the input large load. On the other hand, the instrument panel reinforcement I has a small amount of displacement toward the vehicle rear side even when a large load is input from the vehicle front side. Accordingly, the pedal bracket 10 moves relative to the rear side of the vehicle together with the dash panel P due to the displacement difference between the dash panel P and the instrument panel reinforcement I due to a large load input from the front side of the vehicle.
　図１に示すように、第１実施形態に係るブレーキペダル装置１においては、連結位置として機能する第２支持軸１２が基準線Ｌよりも下方に位置している。そして、後退防止用リンク４０は、第１支持軸１１と第２支持軸１２の相対的な位置関係（距離）を保つように形成されている。これにより、ダッシュパネルＰの後方変位による荷重は、後退防止用リンク４０を第１支持軸１１まわりに下方へ回動させるように作用し、結果として、連結位置である第２支持軸１２を下方へ変位させる。 As shown in FIG. 1, in the brake pedal device 1 according to the first embodiment, the second support shaft 12 that functions as a connection position is located below the reference line L. The retraction preventing link 40 is formed so as to maintain the relative positional relationship (distance) between the first support shaft 11 and the second support shaft 12. As a result, the load caused by the rearward displacement of the dash panel P acts to rotate the retraction preventing link 40 downward around the first support shaft 11, and as a result, the second support shaft 12, which is the connection position, moves downward. Displace to
　又、第２取付位置として機能する固定ボルト５１等の位置は、第１取付位置として機能する第１支持軸１１の位置よりも上方に位置している。この為、当該ブレーキペダル装置１によれば、連結位置である第２支持軸１２を、より確実に下方へ変位させることができる。 Also, the position of the fixing bolt 51 or the like that functions as the second mounting position is located above the position of the first support shaft 11 that functions as the first mounting position. For this reason, according to the said brake pedal apparatus 1, the 2nd support shaft 12 which is a connection position can be displaced below more reliably.
　ダッシュパネルＰの後方変位に伴い、第２支持軸１２が下方に変位すると、中間レバー２５も下方へ移動する。この為、操作ペダル２０は、連結リンク３０を介して引っ張られ、第１支持軸１１まわりに強制的に回動する。図３に示すように、当該ブレーキペダル装置１においては、後退防止用リンク４０及び後退防止部材５０を連結する第２支持軸１２を下方に変位させることで、操作ペダル２０及び中間レバー２５を強制的に回動させて、操作ペダル２０の踏部２１が運転席側へ後退することを抑制できる。 When the second support shaft 12 is displaced downward along with the rearward displacement of the dash panel P, the intermediate lever 25 is also moved downward. For this reason, the operation pedal 20 is pulled via the connecting link 30 and is forcibly rotated around the first support shaft 11. As shown in FIG. 3, in the brake pedal device 1, the operation pedal 20 and the intermediate lever 25 are forcibly displaced by displacing the second support shaft 12 connecting the reverse prevention link 40 and the reverse prevention member 50 downward. It is possible to prevent the stepped portion 21 of the operation pedal 20 from moving backward toward the driver's seat.
　そして、ダッシュパネルＰの後方変位が更に進み、第２支持軸１２が下方に変位していくと、所定の荷重（例えば、固定ボルト５１及びナット５２の締結荷重）を超えた段階で、後退防止部材５０の固定ボルト５１及びナット５２が、スリット６１の幅広部６２に向かって移動していく（図４参照）。固定ボルト５１及びナット５２がスリット６１の幅広部６２に到達した時点で、後退防止部材５０は、スライドブラケット６０から離脱する。これにより、ダッシュパネルＰの後方変位による荷重が、車体側部材であるインパネリインフォースメントＩを大きく変形させる前に取り除かれることになり、結果として、インパネリインフォースメントＩの変形を抑制することができる。即ち、インパネリインフォースメントＩの変形に伴うステアリングの車室内への変位を抑制することができるので、当該ブレーキペダル装置１は、車室内における乗員の上半身を確実に保護することができる。 Then, when the rearward displacement of the dash panel P further proceeds and the second support shaft 12 is displaced downward, the dash panel P is prevented from moving backward when a predetermined load (for example, the fastening load of the fixing bolt 51 and the nut 52) is exceeded. The fixing bolt 51 and the nut 52 of the member 50 move toward the wide portion 62 of the slit 61 (see FIG. 4). When the fixing bolt 51 and the nut 52 reach the wide portion 62 of the slit 61, the retraction preventing member 50 is detached from the slide bracket 60. Thereby, the load due to the rearward displacement of the dash panel P is removed before the instrument panel reinforcement I that is the vehicle body side member is largely deformed, and as a result, the deformation of the instrument panel reinforcement I can be suppressed. That is, since the displacement of the steering into the vehicle interior accompanying the deformation of the instrument panel reinforcement I can be suppressed, the brake pedal device 1 can reliably protect the upper body of the passenger in the vehicle interior.
　以上説明したように、第１実施形態に係るブレーキペダル装置１は、ペダルブラケット１０と、操作ペダル２０と、中間レバー２５と、連結リンク３０と、を有している。当該ブレーキペダル装置１は、踏込み操作に伴う操作ペダル２０の回動に連動して、連結リンク３０を介して中間レバー２５を回動させることができ、もって、ブレーキブースタＢのオペレーティングロッドＲを車両前側へ変位させ得る。 As described above, the brake pedal device 1 according to the first embodiment includes the pedal bracket 10, the operation pedal 20, the intermediate lever 25, and the connecting link 30. The brake pedal device 1 can rotate the intermediate lever 25 via the connecting link 30 in conjunction with the rotation of the operation pedal 20 associated with the stepping operation, so that the operating rod R of the brake booster B is moved to the vehicle. It can be displaced to the front side.
　第１実施形態に係るブレーキペダル装置１は、更に、後退防止用リンク４０と、後退防止部材５０を有している。後退防止用リンク４０と後退防止部材５０を連結する第２支持軸１２は、図１に示すように、基準線Ｌよりも下方に位置している。これにより、当該ブレーキペダル装置１は、ダッシュパネルＰが車両後側へ変位し、ダッシュパネルＰとインパネリインフォースメントＩ等との間隔が狭まっていくと、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ移動させることができる（図３、図４参照）。この結果、当該ブレーキペダル装置１においては、中間レバー２５も第２支持軸１２と共に下方に移動する為、操作ペダル２０は、連結リンク３０を介して、第１支持軸１１を中心として車両前方側へ回動することになる。 The brake pedal device 1 according to the first embodiment further includes a reverse prevention link 40 and a reverse prevention member 50. As shown in FIG. 1, the second support shaft 12 that connects the retraction prevention link 40 and the retraction prevention member 50 is positioned below the reference line L. Thereby, when the dash panel P is displaced to the rear side of the vehicle and the distance between the dash panel P and the instrument panel reinforcement I and the like is narrowed, the brake pedal device 1 of the brake pedal device 1 The 2nd support shaft 12 which is a connection position can be moved below (refer FIG. 3, FIG. 4). As a result, in the brake pedal device 1, since the intermediate lever 25 also moves downward together with the second support shaft 12, the operation pedal 20 is located on the vehicle front side around the first support shaft 11 via the connection link 30. It will turn to.
　即ち、ブレーキペダル装置１は、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を、第１取付位置と第２取付位置とを結ぶ基準線Ｌよりも下方に位置させることによって、車両の前方衝突等によって前記ダッシュパネルＰが車両後側へ変位した場合に、操作ペダル２０及び中間レバー２５を強制的に回動させることができる。これにより、当該ブレーキペダル装置１は、結果として、操作ペダル２０の踏部２１を車両後側へ変位することを抑制することができる（図３、図４参照）。又、当該ブレーキペダル装置１によれば、ダッシュパネルＰを車両後方側へ変位させる車両前方側からの荷重を、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ移動させる方向に作用させることができるので、インパネリインフォースメントＩ等の変形を抑制することができる。これにより、当該ブレーキペダル装置１は、インパネリインフォースメントＩに配設されたステアリングの車室内への変位を抑制して、車室内における乗員の上半身を確実に保護することができる。 That is, the brake pedal device 1 positions the second support shaft 12, which is a connection position of the reverse movement prevention link 40 and the reverse movement prevention member 50, below the reference line L that connects the first attachment position and the second attachment position. By doing so, the operation pedal 20 and the intermediate lever 25 can be forcibly rotated when the dash panel P is displaced to the rear side of the vehicle due to a frontal collision of the vehicle or the like. Thereby, the said brake pedal apparatus 1 can suppress displacing the step part 21 of the operation pedal 20 to the vehicle rear side as a result (refer FIG. 3, FIG. 4). Further, according to the brake pedal device 1, the load from the vehicle front side that displaces the dash panel P to the vehicle rear side is applied to the second support shaft 12, which is the connection position between the reverse prevention link 40 and the reverse prevention member 50. Since it can be made to act in the direction made to move below, deformation of instrument panel reinforcement I etc. can be controlled. Thereby, the said brake pedal apparatus 1 can suppress the displacement to the vehicle interior of the steering arrange | positioned in the instrument panel reinforcement I, and can protect the upper body of the passenger | crew in a vehicle interior reliably.
　そして、当該ブレーキペダル装置１においては、図２等に示すように、後退防止部材５０は、車両後方側へ所定量変位した場合に、車体側部材であるインパネリインフォースメントＩに固設されたスライドブラケット６０から離脱可能に取り付けられている。これにより、当該ブレーキペダル装置１によれば、ダッシュパネルＰを車両後方側へ変位させる車両前方側からの荷重が車体側部材であるインパネリインフォースメントＩの変形を引き起こす前に、その荷重を除外することができる。この結果、当該ブレーキペダル装置１は、ステアリングとの接触等を防止して、乗員の確実な保護に貢献し得る。 In the brake pedal device 1, as shown in FIG. 2 and the like, when the reverse prevention member 50 is displaced by a predetermined amount toward the rear side of the vehicle, a slide fixed to the instrument panel reinforcement I that is a vehicle body side member. The bracket 60 is detachably attached. Thereby, according to the said brake pedal apparatus 1, before the load from the vehicle front side which displaces the dash panel P to the vehicle rear side causes the deformation | transformation of the instrument panel reinforcement I which is a vehicle body side member, the load is excluded. be able to. As a result, the brake pedal device 1 can contribute to reliable protection of the occupant by preventing contact with the steering and the like.
　そして、第１実施形態に係るブレーキペダル装置１において、前記第２取付位置である固定ボルト５１等の位置は、前記第１取付位置として機能する第１支持軸１１よりも上方に位置している。この為、車両の前方衝突等によって前記ダッシュパネルＰが車両後側へ変位した場合に、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ確実に移動させることができる。即ち、当該ブレーキペダル装置１によれば、操作ペダル２０の踏部２１が車両後側へ変位することを確実に抑制することができると同時に、インパネリインフォースメントＩの変形を抑制することができ、結果として、乗員の上半身の確実な保護に貢献し得る。 In the brake pedal device 1 according to the first embodiment, the position of the fixing bolt 51 or the like that is the second mounting position is located above the first support shaft 11 that functions as the first mounting position. . For this reason, when the dash panel P is displaced to the rear side of the vehicle due to a frontal collision of the vehicle or the like, the second support shaft 12, which is the connection position of the reverse prevention link 40 and the reverse prevention member 50, is reliably moved downward. be able to. That is, according to the brake pedal device 1, it is possible to reliably suppress the stepped portion 21 of the operation pedal 20 from being displaced toward the rear side of the vehicle, and at the same time, it is possible to suppress the deformation of the instrument panel reinforcement I. As a result, it can contribute to reliable protection of the upper body of the occupant.
　又、第１実施形態に係るブレーキペダル装置１においては、第１支持軸１１は、前記ペダルブラケット１０に対して操作ペダル２０を回動可能に支持すると共に、前記ペダルブラケット１０に対して後退防止用リンク４０を回動可能に支持している。即ち、ブレーキペダル装置１によれば、第１支持軸１１に、ペダルブラケット１０に対して操作ペダル２０を回動可能に支持する機能に加えて、ペダルブラケット１０に対して後退防止用リンク４０を回動可能に支持する機能を持たせることができる。即ち、当該ブレーキペダル装置１は、部品点数を削減して製造コストを低減することができる。 In the brake pedal device 1 according to the first embodiment, the first support shaft 11 supports the operation pedal 20 so as to be rotatable with respect to the pedal bracket 10 and prevents the pedal bracket 10 from moving backward. The link 40 is rotatably supported. That is, according to the brake pedal device 1, in addition to the function of supporting the operation pedal 20 on the first support shaft 11 so as to be rotatable with respect to the pedal bracket 10, the retraction preventing link 40 is provided with respect to the pedal bracket 10. It is possible to provide a function of supporting the rotation. That is, the brake pedal device 1 can reduce the manufacturing cost by reducing the number of parts.
　更に、当該ブレーキペダル装置１において、第２支持軸１２は、中間レバー２５と後退防止用リンク４０とを相互に回動可能に支持すると共に、後退防止用リンク４０と後退防止部材５０とを回動可能に連結している。即ち、当該ブレーキペダル装置１によれば、第２支持軸１２に、中間レバー２５と後退防止用リンク４０とを相互に回動可能に支持する機能に加えて、後退防止用リンク４０と後退防止部材５０とを回動可能に連結する機能を持たせることができる。当該ブレーキペダル装置１は、部品点数を削減して製造コストを低減することができる。 Further, in the brake pedal device 1, the second support shaft 12 supports the intermediate lever 25 and the reverse movement prevention link 40 so as to be rotatable relative to each other, and rotates the reverse movement prevention link 40 and the reverse movement prevention member 50. It is linked movably. That is, according to the brake pedal device 1, in addition to the function of rotatably supporting the intermediate lever 25 and the reverse movement prevention link 40 on the second support shaft 12, the reverse movement prevention link 40 and the backward movement prevention link are provided. It is possible to provide a function of connecting the member 50 so as to be rotatable. The brake pedal device 1 can reduce manufacturing costs by reducing the number of parts.
（第２実施形態）
　次に、上述した第１実施形態と異なる実施形態（第２実施形態）に係るブレーキペダル装置１の概略構成について、図５～図７を参照しつつ詳細に説明する。尚、第２実施形態に係るブレーキペダル装置１は、ペダルブラケット１０、後退防止用リンク４０の構成を除き、上述した第１実施形態に係るブレーキペダル装置１と同様の構成を有している。従って、以下の説明においては、第１実施形態と同様の構成についての説明を省略し、相違する構成について詳細に説明する。 (Second Embodiment)
Next, a schematic configuration of a brake pedal device 1 according to an embodiment (second embodiment) different from the above-described first embodiment will be described in detail with reference to FIGS. The brake pedal device 1 according to the second embodiment has the same configuration as the brake pedal device 1 according to the first embodiment described above, except for the configurations of the pedal bracket 10 and the reverse prevention link 40. Therefore, in the following description, the description of the same configuration as that of the first embodiment is omitted, and a different configuration will be described in detail.
（第２実施形態に係るブレーキペダル装置の概略構成）
　第２実施形態に係るブレーキペダル装置１においても、ペダルブラケット１０は、ダッシュパネルＰの車室側に対して、ボルト等を用いて固定されており、車幅方向に間隔をおいて対向する一対の側板を有している。当該ペダルブラケット１０は、第１実施形態と同様の第１支持軸１１に加えて、取付軸１３を有している。 (Schematic configuration of the brake pedal device according to the second embodiment)
Also in the brake pedal device 1 according to the second embodiment, the pedal bracket 10 is fixed to the passenger compartment side of the dash panel P using bolts or the like, and is a pair opposed to each other at an interval in the vehicle width direction. Side plates. The pedal bracket 10 has an attachment shaft 13 in addition to the first support shaft 11 similar to that of the first embodiment.
　第２実施形態に係る第１支持軸１１は、ペダルブラケット１０における一対の側板の間に亘って、略水平で且つ車幅方向と略平行に延びており、操作ペダル２０の上部を回動可能に支持している。この点、第２実施形態に係る第１支持軸１１は、第１実施形態と異なり、後退防止用リンク４０の端部の支持に用いられていない。 The first support shaft 11 according to the second embodiment extends between the pair of side plates in the pedal bracket 10 and is substantially horizontal and substantially parallel to the vehicle width direction, so that the upper part of the operation pedal 20 can be rotated. I support it. In this regard, unlike the first embodiment, the first support shaft 11 according to the second embodiment is not used to support the end portion of the retraction preventing link 40.
　そして、第２実施形態においても、第２支持軸１２は、操作ペダル２０よりも車両後側において、第１支持軸１１と平行に伸びるように配設されている。そして、当該第２支持軸１２は、オペレーティングロッドＲが接続された中間レバー２５の下部を回動可能に支持すると共に、後退防止用リンク４０の他端部を回動可能に支持している。更に、第２実施形態に係る第２支持軸１２は、第１実施形態と同様に、後退防止用リンク４０及び後退防止部材５０を相互に回動可能に連結しており、本発明における連結位置として機能する。 And also in 2nd Embodiment, the 2nd support shaft 12 is arrange | positioned so that it may extend in parallel with the 1st support shaft 11 in the vehicle rear side rather than the operation pedal 20. FIG. The second support shaft 12 rotatably supports the lower portion of the intermediate lever 25 to which the operating rod R is connected, and rotatably supports the other end of the retraction preventing link 40. Furthermore, the 2nd support shaft 12 which concerns on 2nd Embodiment has connected the link 40 for reverse movement and the reverse movement prevention member 50 so that rotation is mutually possible like the 1st Embodiment, and the connection position in this invention Function as.
　第２実施形態に係るペダルブラケット１０には、取付軸１３が形成されている。当該取付軸１３は、第１支持軸１１よりも上方であって、且つ、スライドブラケット６０に対する後退防止部材５０の取付位置（即ち、固定ボルト５１等の位置）よりも下方となる位置において、第１支持軸１１と平行に伸びるように配設されている。そして、図５～図７に示すように、当該取付軸１３は、後退防止用リンク４０の一端部をペダルブラケット１０に対して回動可能に取り付ける機能を果たしており、本発明における第１取付位置に相当する。 A mounting shaft 13 is formed on the pedal bracket 10 according to the second embodiment. The mounting shaft 13 is above the first support shaft 11 and at a position below the mounting position of the receding prevention member 50 with respect to the slide bracket 60 (that is, the position of the fixing bolt 51 etc.). 1 It is arrange | positioned so that it may extend in parallel with the support shaft 11. As shown in FIG. As shown in FIGS. 5 to 7, the attachment shaft 13 has a function of attaching one end portion of the retreat prevention link 40 to the pedal bracket 10 so as to be rotatable, and is a first attachment position in the present invention. It corresponds to.
　そして、第２実施形態に係る後退防止用リンク４０は、第１実施形態と同様に、ペダルブラケット１０の各側板に沿って配置された鋼板製の部材である。後退防止用リンク４０における車両前方側の端部は、ペダルブラケット１０の取付軸１３によって回動可能に取り付けられており、車両後方側の端部は、第２支持軸１２によって支持されている。ここで、取付軸１３は、ペダルブラケット１０に配設される一方で、第２支持軸１２は、ペダルブラケット１０を介さずに配設されている。従って、後退防止用リンク４０は、第２支持軸１２の移動に伴い、取付軸１３まわりに回動し得る。 Further, the reverse prevention link 40 according to the second embodiment is a steel plate member disposed along each side plate of the pedal bracket 10 as in the first embodiment. An end portion on the vehicle front side of the reverse preventing link 40 is rotatably attached by an attachment shaft 13 of the pedal bracket 10, and an end portion on the vehicle rear side is supported by the second support shaft 12. Here, the attachment shaft 13 is disposed on the pedal bracket 10, while the second support shaft 12 is disposed without the pedal bracket 10. Accordingly, the retraction preventing link 40 can rotate around the attachment shaft 13 as the second support shaft 12 moves.
　以上のように構成することで、第２実施形態に係るブレーキペダル装置１においては、図５に示すように、本発明における第２取付位置として機能する固定ボルト５１及びナット５２の位置は、本発明における第１取付位置として機能する取付軸１３よりも上方に位置している。そして、第１取付位置と第２取付位置を結ぶ基準線Ｌは、車両後方側に向かうほど上方となるように傾斜している。そして、第２実施形態に係るブレーキペダル装置１では、本発明における連結位置として機能する第２支持軸１２は、第１取付位置と第２取付位置を結ぶ基準線Ｌよりも下方に位置することになる。 With the configuration as described above, in the brake pedal device 1 according to the second embodiment, as shown in FIG. 5, the positions of the fixing bolt 51 and the nut 52 functioning as the second mounting position in the present invention are It is located above the mounting shaft 13 that functions as the first mounting position in the invention. And the reference line L which connects a 1st attachment position and a 2nd attachment position inclines so that it may become upward, so that it goes to the vehicle rear side. And in the brake pedal apparatus 1 which concerns on 2nd Embodiment, the 2nd support shaft 12 which functions as a connection position in this invention is located below the reference line L which ties a 1st attachment position and a 2nd attachment position. become.
(第２実施形態に係るブレーキペダル装置の前方衝突時における動作)
　次に、第２実施形態に係るブレーキペダル装置１の車両の前方衝突時における動作について、図６、図７を参照しつつ詳細に説明する。第２実施形態においても、車両の前方衝突等によって車両前側から大荷重が入力された場合、ダッシュパネルＰは、入力された大荷重によって車両後側へ変位する。そして、車両前側から入力された大荷重によるダッシュパネルＰとインパネリインフォースメントＩとの変位差によって、ブレーキペダル装置１は、ダッシュパネルＰと共に、相対的に車両後側へ移動する。 (Operation of the brake pedal device according to the second embodiment at the time of forward collision)
Next, the operation of the brake pedal device 1 according to the second embodiment at the time of a vehicle front collision will be described in detail with reference to FIGS. Also in the second embodiment, when a large load is input from the front side of the vehicle due to a frontal collision or the like of the vehicle, the dash panel P is displaced to the rear side of the vehicle due to the input large load. The brake pedal device 1 moves relative to the rear side of the vehicle together with the dash panel P due to a displacement difference between the dash panel P and the instrument panel reinforcement I due to a large load input from the front side of the vehicle.
　図５に示すように、第２実施形態に係るブレーキペダル装置１においては、連結位置として機能する第２支持軸１２が基準線Ｌよりも下方に位置しており、後退防止用リンク４０は、取付軸１３と第２支持軸１２の相対的な位置関係（距離）を保つように形成されている。これにより、ダッシュパネルＰの後方変位による荷重は、後退防止用リンク４０を取付軸１３まわりに下方へ回動させるように作用する。この結果、ダッシュパネルＰの後方変位による荷重は、連結位置である第２支持軸１２を下方へ変位させる。 As shown in FIG. 5, in the brake pedal device 1 according to the second embodiment, the second support shaft 12 that functions as a connection position is located below the reference line L, and the reverse prevention link 40 is The mounting shaft 13 and the second support shaft 12 are formed to maintain a relative positional relationship (distance). As a result, the load caused by the rearward displacement of the dash panel P acts to rotate the retraction preventing link 40 downward around the attachment shaft 13. As a result, the load due to the rearward displacement of the dash panel P displaces the second support shaft 12 that is the connection position downward.
　又、第２実施形態においても、第２取付位置として機能する固定ボルト５１等の位置は、第１取付位置として機能する取付軸１３の位置よりも上方に位置している。従って、当該ブレーキペダル装置１によれば、連結位置である第２支持軸１２を、より確実に下方へ変位させることができる。 Also in the second embodiment, the position of the fixing bolt 51 or the like that functions as the second mounting position is located above the position of the mounting shaft 13 that functions as the first mounting position. Therefore, according to the brake pedal device 1, the second support shaft 12 that is the connection position can be displaced more reliably downward.
　そして、第２実施形態においても、ダッシュパネルＰの後方変位に伴い、第２支持軸１２が下方に変位すると、中間レバー２５も下方へ移動する。この中間レバー２５の移動によって、操作ペダル２０は、連結リンク３０を介して引っ張られ、第１支持軸１１まわりに強制的に回動する。即ち、図６に示すように、第２実施形態に係るブレーキペダル装置１においては、後退防止用リンク４０及び後退防止部材５０を連結する第２支持軸１２を下方に変位させることで、操作ペダル２０及び中間レバー２５を強制的に回動させて、操作ペダル２０の踏部２１が運転席側へ後退することを抑制できる。 Also in the second embodiment, when the second support shaft 12 is displaced downward along with the rearward displacement of the dash panel P, the intermediate lever 25 is also moved downward. Due to the movement of the intermediate lever 25, the operation pedal 20 is pulled via the connection link 30 and is forcibly rotated around the first support shaft 11. That is, as shown in FIG. 6, in the brake pedal device 1 according to the second embodiment, the second support shaft 12 that connects the retraction prevention link 40 and the retraction prevention member 50 is displaced downward, thereby operating the operation pedal. 20 and the intermediate lever 25 can be forcibly rotated to prevent the stepped portion 21 of the operation pedal 20 from moving backward toward the driver's seat.
　そして、第２実施形態においても、ダッシュパネルＰの後方変位が更に進み、第２支持軸１２が下方に変位していくと、所定の荷重（例えば、固定ボルト５１及びナット５２の締結荷重）を超えた段階で、後退防止部材５０の固定ボルト５１等が、スリット６１の幅広部６２に向かって移動していく（図７参照）。そして、固定ボルト５１及びナット５２がスリット６１の幅広部６２に到達した時点で、後退防止部材５０は、スライドブラケット６０から離脱する。これにより、第２実施形態に係るブレーキペダル装置１においても、ダッシュパネルＰの後方変位による荷重が、車体側部材であるインパネリインフォースメントＩを大きく変形させる前に取り除かれることになる。即ち、インパネリインフォースメントＩの変形に伴うステアリングの車室内への変位を抑制することができるので、第２実施形態に係るブレーキペダル装置１も、車室内における乗員の上半身を確実に保護することができる。 Also in the second embodiment, when the rearward displacement of the dash panel P further proceeds and the second support shaft 12 is displaced downward, a predetermined load (for example, a fastening load of the fixing bolt 51 and the nut 52) is applied. At the stage of exceeding, the fixing bolt 51 and the like of the receding prevention member 50 move toward the wide portion 62 of the slit 61 (see FIG. 7). Then, when the fixing bolt 51 and the nut 52 reach the wide portion 62 of the slit 61, the receding prevention member 50 is detached from the slide bracket 60. Thereby, also in the brake pedal device 1 according to the second embodiment, the load due to the rearward displacement of the dash panel P is removed before the instrument panel reinforcement I that is the vehicle body side member is largely deformed. That is, since the displacement of the steering into the vehicle interior accompanying the deformation of the instrument panel reinforcement I can be suppressed, the brake pedal device 1 according to the second embodiment can also reliably protect the upper body of the passenger in the vehicle interior. it can.
　以上説明したように、第２実施形態に係るブレーキペダル装置１は、第１実施形態と同様に、ペダルブラケット１０と、操作ペダル２０と、中間レバー２５と、連結リンク３０と、を有している。当該ブレーキペダル装置１は、踏込み操作に伴う操作ペダル２０の回動に連動して、連結リンク３０を介して中間レバー２５を回動させることができ、結果として、ブレーキブースタＢのオペレーティングロッドＲを車両前側へ変位させ得る。 As described above, the brake pedal device 1 according to the second embodiment includes the pedal bracket 10, the operation pedal 20, the intermediate lever 25, and the connecting link 30, as in the first embodiment. Yes. The brake pedal device 1 can rotate the intermediate lever 25 via the connecting link 30 in conjunction with the rotation of the operation pedal 20 accompanying the stepping operation. As a result, the operating rod R of the brake booster B can be moved. It can be displaced toward the front of the vehicle.
　そして、第２実施形態に係るブレーキペダル装置１は、第１実施形態と同様に、後退防止用リンク４０と、後退防止部材５０を有している。そして、後退防止用リンク４０と後退防止部材５０を連結する第２支持軸１２は、基準線Ｌよりも下方に位置している（図５参照）。これにより、当該ブレーキペダル装置１は、ダッシュパネルＰが車両後側へ変位して、ダッシュパネルＰとインパネリインフォースメントＩ等との間隔が狭まっていくと、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ移動させ、第２支持軸１２と共に中間レバー２５を下方に移動させることができる（図６、図７参照）。この結果、当該ブレーキペダル装置１においては、中間レバー２５の下方移動に伴い、操作ペダル２０が、連結リンク３０を介して引っ張られる。この為、当該ブレーキペダル装置１は、操作ペダル２０を、第１支持軸１１を中心として車両前方側へ回動させて、操作ペダル２０の踏部２１を車両後側へ変位することを抑制することができる。 And the brake pedal apparatus 1 which concerns on 2nd Embodiment has the link 40 for a reverse movement, and the reverse movement prevention member 50 similarly to 1st Embodiment. And the 2nd support shaft 12 which connects the link 40 for a back prevention and the back prevention member 50 is located below the reference line L (refer FIG. 5). Thereby, when the dash panel P is displaced to the rear side of the vehicle and the distance between the dash panel P and the instrument panel reinforcement I and the like is narrowed, the brake pedal device 1 is configured to prevent the retraction prevention link 40 and the retraction prevention member 50. The second support shaft 12, which is the connecting position, can be moved downward, and the intermediate lever 25 can be moved downward together with the second support shaft 12 (see FIGS. 6 and 7). As a result, in the brake pedal device 1, the operation pedal 20 is pulled via the connection link 30 as the intermediate lever 25 moves downward. For this reason, the brake pedal device 1 suppresses displacement of the stepped portion 21 of the operation pedal 20 toward the vehicle rear side by rotating the operation pedal 20 around the first support shaft 11 toward the vehicle front side. be able to.
　又、第２実施形態に係るブレーキペダル装置１においても、ダッシュパネルＰを車両後方側へ変位させる車両前方側からの荷重を、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ移動させる方向に作用させることができ、インパネリインフォースメントＩ等の変形を抑制することができる。これにより、当該ブレーキペダル装置１は、インパネリインフォースメントＩに配設されたステアリングの車室内への変位を抑制して、車室内における乗員の上半身を確実に保護することができる。 Also in the brake pedal device 1 according to the second embodiment, the load from the front side of the vehicle that displaces the dash panel P toward the rear side of the vehicle is the second connecting position of the reverse prevention link 40 and the reverse prevention member 50. It can be made to act in the direction which moves support shaft 12 below, and deformation of instrument panel reinforcement I etc. can be controlled. Thereby, the said brake pedal apparatus 1 can suppress the displacement to the vehicle interior of the steering arrange | positioned in the instrument panel reinforcement I, and can protect the upper body of the passenger | crew in a vehicle interior reliably.
　そして、第２実施形態に係るブレーキペダル装置１においても、後退防止部材５０は、車両後方側へ所定量変位した場合に、車体側部材であるインパネリインフォースメントＩに固設されたスライドブラケット６０から離脱可能に取り付けられている。これにより、第２実施形態においても、ダッシュパネルＰを車両後方側へ変位させる車両前方側からの荷重が車体側部材であるインパネリインフォースメントＩの変形を引き起こす前に、その荷重を除外することができる。当該ブレーキペダル装置１は、結果として、ステアリングとの接触等を防止して、乗員の確実な保護に貢献し得る。 And also in the brake pedal apparatus 1 which concerns on 2nd Embodiment, when the reverse movement prevention member 50 is displaced predetermined amount to the vehicle rear side, from the slide bracket 60 fixed to the instrument panel reinforcement I which is a vehicle body side member. Removably attached. Thereby, also in 2nd Embodiment, before the load from the vehicle front side which displaces the dash panel P to the vehicle rear side causes the deformation | transformation of the instrument panel reinforcement I which is a vehicle body side member, it is possible to exclude the load. it can. As a result, the brake pedal device 1 can prevent contact with the steering and the like, thereby contributing to reliable protection of the occupant.
　又、第２実施形態においても、前記第２取付位置である固定ボルト５１等の位置は、前記第１取付位置として機能する取付軸１３よりも上方に位置している。この為、車両の前方衝突等によって前記ダッシュパネルＰが車両後側へ変位した場合に、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ確実に移動させることができる。即ち、当該ブレーキペダル装置１によれば、操作ペダル２０の踏部２１が車両後側へ変位することを確実に抑制することができると同時に、インパネリインフォースメントＩの変形を抑制することができ、結果として、乗員の上半身の確実な保護に貢献し得る。 Also in the second embodiment, the position of the fixing bolt 51 or the like that is the second mounting position is located above the mounting shaft 13 that functions as the first mounting position. For this reason, when the dash panel P is displaced to the rear side of the vehicle due to a frontal collision of the vehicle or the like, the second support shaft 12, which is the connection position of the reverse prevention link 40 and the reverse prevention member 50, is reliably moved downward. be able to. That is, according to the brake pedal device 1, it is possible to reliably suppress the stepped portion 21 of the operation pedal 20 from being displaced toward the rear side of the vehicle, and at the same time, it is possible to suppress the deformation of the instrument panel reinforcement I. As a result, it can contribute to reliable protection of the upper body of the occupant.
　そして、第２実施形態においても、第２支持軸１２は、中間レバー２５と後退防止用リンク４０とを相互に回動可能に支持すると共に、後退防止用リンク４０と後退防止部材５０とを回動可能に連結している。従って、当該ブレーキペダル装置１は、部品点数を削減して製造コストを低減することができる。 Also in the second embodiment, the second support shaft 12 supports the intermediate lever 25 and the retraction preventing link 40 so as to be rotatable relative to each other, and rotates the retraction preventing link 40 and the retraction preventing member 50. It is linked movably. Therefore, the brake pedal device 1 can reduce the manufacturing cost by reducing the number of parts.

An end portion on the vehicle front side of the reverse prevention link 40 is rotatably attached by an attachment shaft 13 of the pedal bracket 10, and an end portion on the vehicle rear side is supported by the second support shaft 12. . Here, the attachment shaft 13 is disposed on the pedal bracket 10, while the second support shaft 12 is disposed without the pedal bracket 10. For this reason, the retraction preventing link 40 can rotate around the attachment shaft 13 as the second support shaft 12 moves. In the third embodiment, the distance between the attachment shaft 13 and the second support shaft 12 positioned at both ends of the retreat prevention link 40 is referred to as a first distance DA.
　第３実施形態においては、後退防止部材５０は、第１実施形態、第２実施形態と同様に、その一端部が車体側部材を構成するスライドブラケット６０に対して取り付けられると共に、第２支持軸１２を介して、後退防止用リンク４０に対して回動可能に連結されている。当該後退防止部材５０は、車両の前方衝突等により荷重が加わった場合には、車体側部材を構成するスライドブラケット６０から離脱するように取り付けられている（図２参照）。そして、第３実施形態においては、後退防止部材５０の一端側に位置する固定ボルト５１等の位置（即ち、スライドブラケット６０に対する後退防止部材５０の取付位置）と第２支持軸１２の間の距離を、第２距離ＤＢといい、当該第２距離ＤＢは、上述した第１距離ＤＡよりも短く設定されている。 In the third embodiment, the receding prevention member 50 is attached to the slide bracket 60 that constitutes the vehicle body side member, and the second support shaft, as in the first and second embodiments. 12, the retraction preventing link 40 is rotatably connected to the link. The reverse prevention member 50 is attached so as to be detached from the slide bracket 60 constituting the vehicle body side member when a load is applied due to a forward collision of the vehicle or the like (see FIG. 2). In the third embodiment, the distance between the second support shaft 12 and the position of the fixing bolt 51 or the like located on one end side of the receding prevention member 50 (that is, the mounting position of the receding preventing member 50 with respect to the slide bracket 60). Is called the second distance DB, and the second distance DB is set shorter than the first distance DA described above.
　以上のように構成することで、第３実施形態に係るブレーキペダル装置１においては、図８に示すように、本発明における第２取付位置として機能する固定ボルト５１及びナット５２の位置は、本発明における第１取付位置として機能する取付軸１３と同じ高さに位置している。第１取付位置と第２取付位置を結ぶ基準線Ｌは、車両の前後方向に関して水平に伸びている。そして、第３実施形態に係るブレーキペダル装置１では、本発明における連結位置として機能する第２支持軸１２は、第１取付位置と第２取付位置を結ぶ基準線Ｌよりも下方に位置することになる。更に、第３実施形態においては、前記第１取付位置である取付軸１３と前記連結位置である第２支持軸１２との間を結ぶ第１距離ＤＡは、前記第２取付位置である固定ボルト５１等の位置と前記連結位置である第２支持軸１２とを結ぶ第２距離ＤＢよりも長い（図８参照）。 With the configuration as described above, in the brake pedal device 1 according to the third embodiment, as shown in FIG. 8, the positions of the fixing bolt 51 and the nut 52 functioning as the second attachment position in the present invention are It is located at the same height as the mounting shaft 13 that functions as the first mounting position in the invention.

It is longer than the second distance DB connecting the position 51 or the like and the second support shaft 12 that is the connecting position (see FIG. 8).
(第３実施形態に係るブレーキペダル装置の前方衝突時における動作)
　次に、第３実施形態に係るブレーキペダル装置１の車両の前方衝突時における動作について、図９、図１０を参照しつつ詳細に説明する。第３実施形態においても、車両の前方衝突等によって車両前側から大荷重が入力された場合、ダッシュパネルＰは、入力された大荷重によって車両後側へ変位して、ブレーキペダル装置１をダッシュパネルＰと共に、相対的に車両後側へ移動させる。 (Operation of Brake Pedal Device According to Third Embodiment at Front Collision)
Next, the operation of the brake pedal device 1 according to the third embodiment at the time of a vehicle front collision will be described in detail with reference to FIGS. 9 and 10. Also in the third embodiment, when a large load is input from the front side of the vehicle due to a vehicle frontal collision or the like, the dash panel P is displaced to the rear side of the vehicle by the input large load, and the brake pedal device 1 is moved to the dash panel. Along with P, the vehicle is moved relatively to the rear side of the vehicle.
　図８に示すように、第３実施形態に係るブレーキペダル装置１においては、連結位置として機能する第２支持軸１２が基準線Ｌよりも下方に位置しており、後退防止用リンク４０は、取付軸１３と第２支持軸１２の相対的な位置関係（距離）を保つように形成されている。これにより、ダッシュパネルＰの後方変位による荷重は、後退防止用リンク４０を取付軸１３まわりに下方へ回動させるように作用し、結果として、連結位置である第２支持軸１２を下方へ変位させることができる。 As shown in FIG. 8, in the brake pedal device 1 according to the third embodiment, the second support shaft 12 that functions as a connection position is located below the reference line L, and the retraction preventing link 40 is The mounting shaft 13 and the second support shaft 12 are formed to maintain a relative positional relationship (distance). As a result, the load due to the rearward displacement of the dash panel P acts to rotate the retraction preventing link 40 downward around the attachment shaft 13, and as a result, the second support shaft 12 that is the connecting position is displaced downward. Can be made.
　ここで、第３実施形態においては、第２取付位置として機能する固定ボルト５１等の位置は、第１取付位置として機能する取付軸１３の位置と同じ高さに位置している。しかしながら、取付軸１３と第２支持軸１２を結ぶ第１距離ＤＡが、固定ボルト５１等と第２支持軸１２を結ぶ第２距離ＤＢよりも長く形成されている。このように形成することにより、当該ブレーキペダル装置１は、第１取付位置と第２取付位置の高さが同じ場合であっても、連結位置である第２支持軸１２を、より確実に下方へ変位させることができる。 Here, in the third embodiment, the position of the fixing bolt 51 or the like that functions as the second mounting position is located at the same height as the position of the mounting shaft 13 that functions as the first mounting position. However, the first distance DA connecting the attachment shaft 13 and the second support shaft 12 is formed longer than the second distance DB connecting the fixing bolt 51 and the second support shaft 12. By forming in this way, the brake pedal device 1 more reliably lowers the second support shaft 12 that is the connecting position even when the heights of the first mounting position and the second mounting position are the same. Can be displaced.
　第３実施形態において、ダッシュパネルＰの後方変位に伴い、第２支持軸１２が下方に変位すると、中間レバー２５も下方へ移動する。この中間レバー２５の移動によって、操作ペダル２０は、連結リンク３０を介して引っ張られ、第１支持軸１１まわりに強制的に回動する。即ち、図９に示すように、第３実施形態に係るブレーキペダル装置１においては、後退防止用リンク４０及び後退防止部材５０を連結する第２支持軸１２を下方に変位させることで、操作ペダル２０及び中間レバー２５を強制的に回動させて、操作ペダル２０の踏部２１が運転席側へ後退することを抑制できる。 In the third embodiment, when the second support shaft 12 is displaced downward with the rearward displacement of the dash panel P, the intermediate lever 25 is also moved downward. Due to the movement of the intermediate lever 25, the operation pedal 20 is pulled via the connection link 30 and is forcibly rotated around the first support shaft 11. That is, as shown in FIG. 9, in the brake pedal device 1 according to the third embodiment, the second support shaft 12 that connects the retraction prevention link 40 and the retraction prevention member 50 is displaced downward, thereby operating the operation pedal. 20 and the intermediate lever 25 can be forcibly rotated to prevent the stepped portion 21 of the operation pedal 20 from moving backward toward the driver's seat.
　そして、第３実施形態においても、ダッシュパネルＰの後方変位が更に進み、第２支持軸１２が下方に変位していくと、所定の荷重（例えば、固定ボルト５１及びナット５２の締結荷重）を超えた段階で、後退防止部材５０の固定ボルト５１等が、スリット６１の幅広部６２に向かって移動していく（図１０参照）。そして、固定ボルト５１及びナット５２がスリット６１の幅広部６２に到達した時点で、後退防止部材５０は、スライドブラケット６０から離脱する。これにより、第３実施形態に係るブレーキペダル装置１でも、ダッシュパネルＰの後方変位による荷重が、車体側部材であるインパネリインフォースメントＩを大きく変形させる前に取り除かれる。即ち、インパネリインフォースメントＩの変形に伴うステアリングの車室内への変位を抑制することができるので、第３実施形態に係るブレーキペダル装置１も、車室内における乗員の上半身を確実に保護することができる。 Also in the third embodiment, when the rear displacement of the dash panel P further proceeds and the second support shaft 12 is displaced downward, a predetermined load (for example, a fastening load of the fixing bolt 51 and the nut 52) is applied. At the stage of exceeding, the fixing bolt 51 and the like of the receding prevention member 50 move toward the wide portion 62 of the slit 61 (see FIG. 10). Then, when the fixing bolt 51 and the nut 52 reach the wide portion 62 of the slit 61, the receding prevention member 50 is detached from the slide bracket 60. Thereby, also in the brake pedal device 1 according to the third embodiment, the load due to the rearward displacement of the dash panel P is removed before the instrument panel reinforcement I that is the vehicle body side member is largely deformed. That is, since the displacement of the steering into the vehicle interior accompanying the deformation of the instrument panel reinforcement I can be suppressed, the brake pedal device 1 according to the third embodiment can also reliably protect the upper body of the passenger in the vehicle interior. it can.
　以上説明したように、第３実施形態に係るブレーキペダル装置１は、第１実施形態と同様に、ペダルブラケット１０と、操作ペダル２０と、中間レバー２５と、連結リンク３０と、を有している。そして、当該ブレーキペダル装置１は、踏込み操作に伴う操作ペダル２０の回動に連動して、連結リンク３０を介して中間レバー２５を回動させることができ、結果として、ブレーキブースタＢのオペレーティングロッドＲを車両前側へ変位させ得る。 As described above, the brake pedal device 1 according to the third embodiment includes the pedal bracket 10, the operation pedal 20, the intermediate lever 25, and the connection link 30, as in the first embodiment. Yes. And the said brake pedal apparatus 1 can rotate the intermediate lever 25 via the connection link 30 in response to rotation of the operation pedal 20 accompanying stepping operation, As a result, the operating rod of the brake booster B R can be displaced toward the front of the vehicle.
　そして、第３実施形態に係るブレーキペダル装置１は、第１実施形態、第２実施形態と同様に、後退防止用リンク４０と、後退防止部材５０を有しており、後退防止用リンク４０と後退防止部材５０を連結する第２支持軸１２は、基準線Ｌよりも下方に位置している（図８参照）。これにより、当該ブレーキペダル装置１は、ダッシュパネルＰが車両後側へ変位し、ダッシュパネルＰとインパネリインフォースメントＩ等との間隔が狭まっていくと、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ移動させ、第２支持軸１２と共に中間レバー２５を下方に移動させることができる（図９、図１０参照）。この結果、当該ブレーキペダル装置１においては、中間レバー２５の下方移動に伴い、操作ペダル２０が連結リンク３０を介して引っ張られる為、操作ペダル２０を、第１支持軸１１を中心として車両前方側へ回動させて、操作ペダル２０の踏部２１を車両後側へ変位することを抑制することができる。 And the brake pedal apparatus 1 which concerns on 3rd Embodiment has the link 40 for a reverse movement, and the reverse movement prevention member 50 similarly to 1st Embodiment and 2nd Embodiment, The link 40 for reverse movement prevention, The 2nd support shaft 12 which connects the retreat prevention member 50 is located below the reference line L (refer FIG. 8). Thereby, when the dash panel P is displaced to the rear side of the vehicle and the distance between the dash panel P and the instrument panel reinforcement I and the like is narrowed, the brake pedal device 1 of the brake pedal device 1 The second support shaft 12 that is the connecting position can be moved downward, and the intermediate lever 25 can be moved downward together with the second support shaft 12 (see FIGS. 9 and 10). As a result, in the brake pedal device 1, as the intermediate lever 25 moves downward, the operation pedal 20 is pulled through the connection link 30, so that the operation pedal 20 is located on the vehicle front side with the first support shaft 11 as the center. It is possible to suppress the stepped portion 21 of the operation pedal 20 from being displaced toward the rear side of the vehicle.
　又、第３実施形態に係るブレーキペダル装置１においても、ダッシュパネルＰを車両後方側へ変位させる車両前方側からの荷重を、後退防止用リンク４０と後退防止部材５０の連結位置である第２支持軸１２を下方へ移動させる方向に作用させることができる。この結果、当該ブレーキペダル装置１は、インパネリインフォースメントＩ等の変形を抑制することができる。これにより、当該ブレーキペダル装置１は、インパネリインフォースメントＩに配設されたステアリングの車室内への変位を抑制して、車室内における乗員の上半身を確実に保護することができる。 Also in the brake pedal device 1 according to the third embodiment, the load from the front side of the vehicle that displaces the dash panel P toward the rear side of the vehicle is the second connecting position between the reverse prevention link 40 and the reverse prevention member 50. It can be made to act in the direction which moves support shaft 12 below. As a result, the brake pedal device 1 can suppress deformation of the instrument panel reinforcement I and the like. Thereby, the said brake pedal apparatus 1 can suppress the displacement to the vehicle interior of the steering arrange | positioned in the instrument panel reinforcement I, and can protect the upper body of the passenger | crew in a vehicle interior reliably.
　そして、第３実施形態に係るブレーキペダル装置１においても、後退防止部材５０は、車両後方側へ所定量変位した場合に、車体側部材であるスライドブラケット６０から離脱可能に取り付けられている。これにより、第３実施形態においても、ダッシュパネルＰを車両後方側へ変位させる車両前方側からの荷重が車体側部材であるインパネリインフォースメントＩの変形を引き起こす前に、その荷重を除外することができる。当該ブレーキペダル装置１は、結果として、ステアリングとの接触等を防止して、乗員の確実な保護に貢献し得る。 Also in the brake pedal device 1 according to the third embodiment, the reverse prevention member 50 is detachably attached to the slide bracket 60 that is a vehicle body side member when the vehicle is displaced by a predetermined amount toward the vehicle rear side. Thereby, also in 3rd Embodiment, before the load from the vehicle front side which displaces the dash panel P to the vehicle rear side causes the deformation | transformation of the instrument panel reinforcement I which is a vehicle body side member, it is possible to exclude the load. it can. As a result, the brake pedal device 1 can prevent contact with the steering and the like, thereby contributing to reliable protection of the occupant.
　第３実施形態において、前記第２取付位置である固定ボルト５１等の位置は、前記第１取付位置として機能する取付軸１３と同じ高さに位置している。しかしながら、取付軸１３と連結位置である第２支持軸１２との間を結ぶ第１距離ＤＡは、固定ボルト５１等の位置と第２支持軸１２とを結ぶ第２距離ＤＢよりも長い。この為、車両の前方衝突等によって前記ダッシュパネルＰが車両後側へ変位した場合に、前記第２支持軸１２を下方へ確実に移動させることができる。即ち、当該ブレーキペダル装置１によれば、操作ペダル２０の踏部２１が車両後側へ変位することを確実に抑制することができる。同時に、当該ブレーキペダル装置１は、インパネリインフォースメントＩの変形を抑制することができ、乗員の上半身の確実な保護に貢献し得る。 In the third embodiment, the positions of the fixing bolts 51 and the like that are the second attachment positions are located at the same height as the attachment shaft 13 that functions as the first attachment position. However, the first distance DA connecting the mounting shaft 13 and the second support shaft 12 that is the connecting position is longer than the second distance DB connecting the position of the fixing bolt 51 and the second support shaft 12. For this reason, when the dash panel P is displaced to the rear side of the vehicle due to a frontal collision of the vehicle or the like, the second support shaft 12 can be reliably moved downward. That is, according to the brake pedal device 1, it is possible to reliably suppress the stepped portion 21 of the operation pedal 20 from being displaced toward the vehicle rear side. At the same time, the brake pedal device 1 can suppress the deformation of the instrument panel reinforcement I, and can contribute to reliable protection of the upper body of the occupant.
　そして、第３実施形態においても、第２支持軸１２は、中間レバー２５と後退防止用リンク４０とを相互に回動可能に支持すると共に、後退防止用リンク４０と後退防止部材５０とを回動可能に連結している。従って、当該ブレーキペダル装置１は、部品点数を削減して製造コストを低減することができる。 Also in the third embodiment, the second support shaft 12 supports the intermediate lever 25 and the retraction preventing link 40 so as to be rotatable relative to each other, and rotates the retraction preventing link 40 and the retraction preventing member 50. It is linked movably. Therefore, the brake pedal device 1 can reduce the manufacturing cost by reducing the number of parts.
　以上、実施形態に基づき本発明を説明したが、本発明は上述した実施形態に何ら限定されるものではなく、本発明の趣旨を逸脱しない範囲内で種々の改良変更が可能である。例えば、上述した各実施形態においては、中間レバー２５の回動軸である第２支持軸１２を用いて、後退防止用リンク４０と後退防止部材５０を相互に回動可能を連結していたが、この態様に限定されるものではなく、後退防止用リンク４０と後退防止部材５０を相互に回動可能を連結する構成を、第２支持軸１２とは別に設けてもよい。 The present invention has been described above based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. For example, in each of the above-described embodiments, the second support shaft 12 that is the rotation shaft of the intermediate lever 25 is used to connect the retraction prevention link 40 and the retraction prevention member 50 to each other so as to be rotatable. However, the present invention is not limited to this mode, and a configuration in which the retraction preventing link 40 and the retraction preventing member 50 are connected to each other so as to be rotatable may be provided separately from the second support shaft 12.
　例えば、図１１に示すように、側面視略Ｌ字状に形成された後退防止用リンク４０の角部分を、第２支持軸１２によって回動可能に支持すると共に、その前方側の端部を、ペダルブラケット１０の取付軸１３に対して回動可能に取り付ける。そして、略Ｌ字状を為す後退防止用リンク４０の後方側端部と、後退防止部材５０とを、連結軸１４によって相互に回動可能に連結する。即ち、この図１１に示す場合、連結軸１４が本発明に係る連結位置として機能し、基準線Ｌよりも下方に位置している。 For example, as shown in FIG. 11, the corner portion of the retraction preventing link 40 formed in a substantially L shape in a side view is rotatably supported by the second support shaft 12, and the front end portion thereof is The pedal bracket 10 is attached to the attachment shaft 13 so as to be rotatable. Then, the rear end portion of the reverse preventing link 40 having a substantially L shape and the reverse preventing member 50 are connected to each other by the connecting shaft 14 so as to be rotatable. That is, in the case shown in FIG. 11, the connecting shaft 14 functions as a connecting position according to the present invention and is positioned below the reference line L.
　従って、この場合においても、ダッシュパネルＰが車両後側へ変位し、ダッシュパネルＰとインパネリインフォースメントＩ等との間隔が狭まっていくと、当該ブレーキペダル装置１は、連結位置である連結軸１４を下方に移動させる。連結軸１４が下方に移動することで後退防止用リンク４０も下方に移動する為、第２支持軸１２と共に中間レバー２５も下方に移動する。これにより、連結リンク３０を介して、操作ペダル２０が下方に引っ張られることになる為、当該ブレーキペダル装置１は、操作ペダル２０を、第１支持軸１１を中心として車両前方側へ回動させて、操作ペダル２０の踏部２１を車両後側へ変位することを抑制することができる。 Therefore, also in this case, when the dash panel P is displaced to the rear side of the vehicle and the distance between the dash panel P and the instrument panel reinforcement I and the like is reduced, the brake pedal device 1 is connected to the connecting shaft 14 which is the connecting position. Is moved downward. As the connecting shaft 14 moves downward, the retraction preventing link 40 also moves downward, so that the intermediate lever 25 also moves downward together with the second support shaft 12. Accordingly, since the operation pedal 20 is pulled downward via the connection link 30, the brake pedal device 1 rotates the operation pedal 20 to the vehicle front side around the first support shaft 11. Thus, displacement of the stepped portion 21 of the operation pedal 20 toward the vehicle rear side can be suppressed.
　又、この場合においても、ダッシュパネルＰを車両後方側へ変位させる車両前方側からの荷重を、連結位置である連結軸１４を下方へ移動させる方向に作用させることができる。この為、当該ブレーキペダル装置１は、インパネリインフォースメントＩ等の変形を抑制することができる。これにより、当該ブレーキペダル装置１は、インパネリインフォースメントＩに配設されたステアリングの車室内への変位を抑制して、車室内における乗員の上半身を確実に保護することができる。 Also in this case, a load from the vehicle front side that displaces the dash panel P toward the vehicle rear side can be applied in a direction in which the connection shaft 14 that is the connection position is moved downward. For this reason, the brake pedal device 1 can suppress deformation of the instrument panel reinforcement I and the like. Thereby, the said brake pedal apparatus 1 can suppress the displacement to the vehicle interior of the steering arrange | positioned in the instrument panel reinforcement I, and can protect the upper body of the passenger | crew in a vehicle interior reliably.
　そして、上述した実施形態においては、スライドブラケット６０に対する後退防止部材５０の離脱構造を、スライドブラケット６０に形成され、幅広部６２を有するスリット６１と、後退防止部材５０に取り付けられた固定ボルト５１及びナット５２によって実現していたが、後退防止部材５０が車両後方側へ所定量変位した場合に、スライドブラケット６０から離脱可能な構成であれば種々の態様を採用することができる。例えば、所定以上の離脱荷重が作用した場合に破断するリベットを用いて、スライドブラケット６０に対して、後退防止部材５０を取り付けてもよい。又、後退防止部材５０に形成された取付軸を、スライドブラケット６０に形成された保持穴で保持するように構成し、当該保持穴における車両後方側に、取付軸の外径よりも小さな開口幅を有する開口部を形成してもよい。この場合、後退防止部材５０が車両後方側に所定量変位した場合に、取付軸を、開口部を介して保持穴外部へ移動させることができ、もって、スライドブラケット６０から後退防止部材５０を離脱させることができる。 In the above-described embodiment, the detachment structure of the receding prevention member 50 with respect to the slide bracket 60 is formed in the slide bracket 60, the slit 61 having the wide portion 62, the fixing bolt 51 attached to the receding prevention member 50, and Although realized by the nut 52, various modes can be adopted as long as the configuration is detachable from the slide bracket 60 when the backward movement preventing member 50 is displaced by a predetermined amount toward the vehicle rear side. For example, the receding prevention member 50 may be attached to the slide bracket 60 by using a rivet that breaks when a predetermined or greater detachment load is applied. Further, the mounting shaft formed on the receding prevention member 50 is configured to be held by a holding hole formed on the slide bracket 60, and an opening width smaller than the outer diameter of the mounting shaft on the vehicle rear side in the holding hole. You may form the opening which has. In this case, when the backward movement preventing member 50 is displaced by a predetermined amount toward the rear side of the vehicle, the mounting shaft can be moved to the outside of the holding hole through the opening, so that the backward movement preventing member 50 is detached from the slide bracket 60. Can be made.
　又、本発明に係る車両用ペダル装置の後退防止装置における各動作を実現することができれば、上述した実施形態に示す態様に限定されるものではなく、ブレーキペダル装置１を構成する各部材の配置を適宜変更することができる。 Moreover, if each operation | movement in the reverse prevention apparatus of the pedal apparatus for vehicles which concerns on this invention can be implement | achieved, it will not be limited to the aspect shown in embodiment mentioned above, Arrangement | positioning of each member which comprises the brake pedal apparatus 1 Can be changed as appropriate.
　更に、本発明に係る車両用ペダル装置の後退防止装置における各動作を実現することができれば、各構成部材の形状を適宜変更し得る。各構成部材の形状は、上述した実施形態におけるブレーキペダル装置１の各構成部材の形状に限定されるものではなく、例えば、各構成部材間の干渉を避ける為に、構成部材夫々の形状を変更してもよい。 Furthermore, if each operation | movement in the reverse prevention apparatus of the pedal apparatus for vehicles which concerns on this invention is realizable, the shape of each structural member can be changed suitably. The shape of each constituent member is not limited to the shape of each constituent member of the brake pedal device 1 in the above-described embodiment. For example, the shape of each constituent member is changed to avoid interference between the constituent members. May be.
