Abstract
Abstract A brake pedal apparatus of a vehicle is provided with a pedal bracket having a shaft and a first fixed portion to a first vehicle body member at its front portion, a pivot bracket rotatable pivoted to the shaft and provided with a pedal shaft apart from the shaft in a longitudinal direction of the vehicle, a pedal arm rotatably pivoted to the pedal shaft, and a lock plate having an engagement portion allowing relative movement with respect to at least the pivot bracket when a backward input over a predetermined load is applied to the pedal bracket and engaging with the pivot bracket in a normal state. In this structure, when the backward input over the predetermined load is applied to the pedal bracket, whereby the lock plate relatively moves, an engagement between the pivot bracket and the lock plate is disconnected, and the pivot bracket is downward rotated around the shaft

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
165 words
A brake pedal apparatus of a vehicle comprising: a pedal bracket having a shaft and a first fixed portion to be fixed to a first vehicle body member at the front thereof; a pivot bracket rotatably pivoted to the shaft and provided with a pedal shaft apart from the shaft in a longitudinal direction of the vehicle; a pedal arm rotatably pivoted to the pedal shaft; a lock plate having an engagement portion allowing relative movement thereof with respect to at least the pivot bracket when a backward input over a predetermined load is applied to the pedal bracket and engaging with the pivot bracket in a normal state; and a rotation promoting member promoting a rotational operation of the pivot bracket, wherein when the backward input over the predetermined load is applied to the pedal bracket, whereby the lock plate relatively moves, an engagement between the pivot bracket and the lock plate is disconnected and the pivot bracket is downward rotated around the shaft.
Claim 2
Dependent Claim
165 words
A brake pedal apparatus of a vehicle comprising: a pedal bracket having a shaft and a first fixed portion to be fixed to a first vehicle body member at the front thereof; a pivot bracket rotatably pivoted to the shaft and provided with a pedal shaft apart from the shaft in a longitudinal direction of the vehicle; a pedal arm rotatably pivoted to the pedal shaft; a lock plate having an engagement portion allowing relative movement thereof with respect to at least the pivot bracket when a backward input over a predetermined load is applied to the pedal bracket and engaging with the pivot bracket in a normal state; and a rotation promoting member promoting a rotational operation of the pivot bracket, wherein when the backward input over the predetermined load is applied to the pedal bracket, whereby the lock plate relatively moves, an engagement between the pivot bracket and the lock plate is disconnected and the pivot bracket is downward rotated around the shaft.
Claim 3
Dependent Claim
95 words
A brake pedal apparatus of a vehicle according to claim 1 , wherein the pedal bracket further has a second fixed portion to be fixed to a lower surface of a second vehicle body member positioned in the upward rear side of the first vehicle body member, at least the engagement portion of the lock plate is movably mounted to the pedal bracket, and a movement absorbing portion allowing a movement in a longitudinal direction between the shaft and the second fixed portion is provided at least between the shaft and the second fixed portion.
Claim 4
Dependent Claim
24 words
A brake pedal apparatus of a vehicle according to claim 2 , wherein the movement absorbing portion is constituted by using a window portion.
Claim 5
Dependent Claim
22 words
A brake pedal apparatus of a vehicle according to claim 3 , wherein the window portion is provided in the pedal bracket.
Claim 6
Dependent Claim
84 words
A brake pedal apparatus of a vehicle according to claim 4 , wherein the pedal bracket is provided with a pair of opposing side surface portions, the second fixed portion is provided at the rear of the lock plate, the lock plate is fixed with a rear end portion of the pedal bracket, and the window portion is provided in the side surface portion of the pedal bracket in the front side from the fixed portion between the pedal bracket and the lock plate.
Claim 7
Dependent Claim
40 words
A brake pedal apparatus of a vehicle according to claim 4 , wherein the second fixed portion has an upper surface portion at the rear of the pedal bracket, and the window portion is formed in the upper surface portion.
Claim 8
Dependent Claim
31 words
A brake pedal apparatus of a vehicle according to claim 6 , wherein an overlap member overlapped with the upper surface portion is provided at the rear of the lock plate.
Claim 9
Dependent Claim
89 words
A brake pedal apparatus of a vehicle according to claim 7 , wherein the rotation promoting member is provided in the lock plate and has a contact portion, and the contact portion is brought into contact with a rear end portion of the pivot bracket above the shaft when the pedal bracket moves between the first fixed portion and the shaft by the movement absorbing portion so that a distance between the first fixed portion and the shaft is reduced, thereby promoting the rotational operation of the pivot bracket.
Claim 10
Dependent Claim
44 words
A brake pedal apparatus of a vehicle according to claim 7 , wherein the rotation promoting member is provided between the pivot bracket and the pedal bracket, and has an urging member capable of urging the pivot bracket downward when the pivot bracket rotates.
Claim 11
Dependent Claim
43 words
A brake pedal apparatus of a vehicle according to claim 1 , further comprising an urging member provided between the pivot bracket and the pedal arm, and capable of urging a pedaling position of the pedal arm forward when the pivot bracket rotates.
Claim 12
Dependent Claim
51 words
A brake pedal apparatus of a vehicle according to claim 1 , further comprising an urging member provided among the pedal shaft, the pedal bracket and the pedal arm, urging the pedal arm backward in the normal state, and capable of urging the pivot bracket downward when the pivot bracket rotates.
Claim 13
Dependent Claim
185 words
A brake pedal apparatus of a vehicle comprising: a pedal bracket having a shaft and a first fixed portion to be fixed to a first vehicle body member at the front thereof; a pivot bracket rotatably pivoted to the shaft and provided with a pedal shaft apart from the shaft in a longitudinal direction of the vehicle; a pedal arm rotatably pivoted to the pedal shaft; and a lock plate having an engagement portion allowing relative movement thereof with respect to at least the pivot bracket when a backward input over a predetermined load is applied to the pedal bracket and engaging with the pivot bracket in a normal state, wherein when the backward input over the predetermined load is applied to the pedal bracket, whereby the lock plate relatively moves, an engagement between the pivot bracket and the lock plate is disconnected and the pivot bracket is downward rotated around the shaft, and wherein the pedal shaft provided in the pivot bracket is set in the downward front side in comparison with the shaft corresponding to a center of rotation of the pivot bracket.
Claim 14
Dependent Claim
