Abstract
Abstract A brake pedal structure for a vehicle includes a pedal bracket provided on a dash panel of the vehicle, a pedal shaft provided on the pedal bracket, a pedal arm pivotally supported by the pedal shaft in a freely rotatable manner around the pedal shaft as a rotational axis, and a push rod connected to the pedal arm for operating a brake system of the vehicle in response to rotation of the pedal arm. The push rod has a portion so as to interrupt the transmission of a load input at the time of collision of said vehicle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
A brake pedal structure for a vehicle, comprising: a pedal bracket provided on a vehicle dash panel; a pedal shaft provided on the pedal bracket; a pedal arm pivotally supported on the pedal shaft so as to be freely rotatable about the pedal shaft, the pedal arm having a notch; a push rod having a pin which is slidably received in the notch to connect the push rod to the pedal arm and to operate a brake system in response to rotation of the pedal arm in a normal state; and a projection which is rigid with the pedal arm and synchronously rotatable therewith to directly act on the push rod such that the projection displaces the pin from the notch in a manner which interrupts a transmission of load input at the time of collision.
Claim 2
Dependent Claim
136 words
A brake pedal structure for a vehicle, comprising: a pedal bracket provided on a vehicle dash panel; a pedal shaft provided on the pedal bracket; a pedal arm pivotally supported on the pedal shaft so as to be freely rotatable about the pedal shaft, the pedal arm having a notch; a push rod having a pin which is slidably received in the notch to connect the push rod to the pedal arm and to operate a brake system in response to rotation of the pedal arm in a normal state; and a projection which is rigid with the pedal arm and synchronously rotatable therewith to directly act on the push rod such that the projection displaces the pin from the notch in a manner which interrupts a transmission of load input at the time of collision.
Claim 3
Dependent Claim
100 words
A brake pedal structure for a vehicle according to claim 1 , wherein the pedal arm comprises a pedal arm member and a push rod lever, wherein the notch is formed in one of the pedal arm member and the push rod lever and opens downwardly with respect to the vehicle, and wherein the projection pushes the push rod downwardly with respect to the vehicle to release engagement between the notch and the pin when a load input, in a rearward direction of the vehicle, is applied through the push rod at the time of a collision of the vehicle.
Claim 4
Dependent Claim
25 words
A brake pedal structure for a vehicle according to claim 2 , wherein the push rod lever is integrally connected to the pedal arm member.
Claim 5
Dependent Claim
58 words
A brake pedal structure for a vehicle according to claim 2 , wherein the notch includes a pin-drop-preventing portion by which the pin is prevented from sliding out of the notch until a load input on the pin in a downward direction of the vehicle exceeds a predetermined value at the time of the collision of the vehicle.
Claim 6
Dependent Claim
24 words
A brake pedal structure for a vehicle according to claim 2 , wherein the notch opens downwardly and forwardly with respect to the vehicle.
Claim 7
Dependent Claim
126 words
A brake pedal structure for a vehicle, comprising: a pedal arm arrangement pivotally supported on a shaft; a push rod operatively connected to the pedal arm arrangement to operate a brake system in response to rotation of the pedal arm, the push rod including a pin which is received in a notch formed in the pedal arm arrangement and which connects the push rod to the pedal arm arrangement; and a projection which forms part of the pedal arm arrangement and rotates to a position wherein it directly engages the push rod such that the pin is displaced out of the notch and the operative connection between the push rod arrangement and the pedal arm is disconnected from the push rod at the time of collision.
Claim 8
Dependent Claim
126 words
A brake pedal structure for a vehicle, comprising: a pedal arm arrangement pivotally supported on a shaft; a push rod operatively connected to the pedal arm arrangement to operate a brake system in response to rotation of the pedal arm, the push rod including a pin which is received in a notch formed in the pedal arm arrangement and which connects the push rod to the pedal arm arrangement; and a projection which forms part of the pedal arm arrangement and rotates to a position wherein it directly engages the push rod such that the pin is displaced out of the notch and the operative connection between the push rod arrangement and the pedal arm is disconnected from the push rod at the time of collision.
Claim 9
Dependent Claim
78 words
A brake pedal structure according to claim 6 , wherein the pedal arm arrangement comprises a pedal arm and a push rod lever which is connected to the pedal arm so that relative movement between the pedal arm and the push rod lever is prevented, and wherein the notch is formed in the push rod lever, the notch being so shaped and dimensioned that engagement between the push rod and the projection displaces the pin along the notch.
