Abstract
Abstract A disclosed brake pedal apparatus for a vehicle includes a pedal bracket (1) provided on a dash panel (4), a pedal shaft (3) provided on the pedal bracket, a pedal arm (2) supported by the pedal shaft in a rotatable manner around the pedal shaft, a first engaging portion (24) provided on the pedal arm, a push rod lever (15) supported by the pedal shaft in a rotatable manner around the pedal shaft and connected to a push rod (14), and a second engaging portion (23) provided on the push rod lever. The push rod lever or the pedal arm is movable along the axial direction of the pedal shaft, and the first and second engaging portions are capable of engaging with each other. The apparatus further includes a biasing member (18) for biasing the push rod lever or the pedal arm in a direction for releasing the engagement between the first and second engaging portions, and a spacer member (17) which, in a normal state, positions the push rod lever and the pedal arm, and which, at the time of collision, detects the collision for allowing movable one of the push rod lever and the pedal arm along the axial direction of the pedal shaft to release the engagement between the first and second engaging portions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
249 words
A brake pedal apparatus for a vehicle, comprising: a pedal bracket provided on a dash panel of said vehicle; a pedal shaft provided on said pedal bracket; a pedal arm pivotally supported by said pedal shaft in
a freely rotatable manner around said pedal shaft as a
rotational axis; a first engaging portion provided on said pedal arm; a push rod lever pivotally supported by said pedal shaft
in a freely rotatable manner around said pedal shaft as a
rotational axis, and connected to a push rod operating a braking
system of said vehicle, said push rod lever or said pedal arm
being freely movable along an axial direction of said pedal
shaft; a second engaging portion provided on said push rod lever,
said first engaging portion and second engaging portion being
capable of engaging with each other; a biasing member biasing said push rod lever or said pedal
arm in a direction to release said engagement between said first
engaging portion and second engaging portion; and a spacer member which, in a normal state, positions said
push rod lever and said pedal arm such that said first engaging
portion and second engaging portion engage with each other, and
which, at the time of collision of said vehicle, detects said
collision and allows movable one of said push rod lever and said
pedal arm along said axial direction of said pedal shaft in said
direction to release said engagement between said first
engaging portion and said second engaging portion.
Claim 2
Dependent Claim
138 words
A brake pedal apparatus for a vehicle according to claim
1, wherein said spacer member is pivotally supported in a freely
rotatable manner around a sub-shaft as a rotational axis
provided in parallel to said pedal shaft, said spacer member
comprising: a hook-like positioning portion fitted in a gap
around said pedal shaft at the side of moving direction of said
pedal arm or said push rod lever in said normal state so as to
engage said first engaging portion and said second engaging
portion with each other; and a collision detecting portion
provided such as to project from said pedal bracket, said
collision detecting portion being engaged, at the time of said
collision of said vehicle, with a movable member which is
relatively movable by a load of said collision so as to rotate
said spacer member.
Claim 3
Dependent Claim
31 words
A brake pedal apparatus for a vehicle according to claim
2, wherein said spacer member is attached to a side wall of one
side of said pedal bracket through said sub-shaft.
Claim 4
Dependent Claim
54 words
A brake pedal apparatus for a vehicle according to claim
1, wherein said first engaging portion is a first meshing
portion, said second engaging portion is a second meshing
portion, and each of said first engaging portion and said second
engaging portion is formed with a plurality of slopes having
said same lead angles.
Claim 5
Dependent Claim
60 words
A brake pedal apparatus for a vehicle according to claim
1, wherein said first engaging portion is provided on an end
surface of a boss portion formed around said rotational axis
of said pedal arm and said second engaging portion is provided
on an end surface of a boss portion formed around said rotational
axis of said push rod lever.
Claim 6
Dependent Claim
62 words
A brake pedal apparatus for a vehicle according to claim
1, wherein a return spring is extending between said push rod
lever and said spacer member, said return spring applying a
rotational force in a rearward direction of said vehicle to said
pedal arm through said push rod lever, and positioning said
spacer member in an initial position in said normal state.
Claim 7
Dependent Claim
63 words
A brake pedal apparatus for a vehicle according to claim
1, wherein a return spring is provided between said pedal
bracket and said push rod lever, said return spring applying
a rotational force in a rearward direction of said vehicle to
said pedal arm through said push rod lever, and biasing said
push rod lever in said axial direction of said pedal shaft.
