Abstract
Abstract A variable ratio parking brake pedal assembly for a motor vehicle including a foot-operated articulated pedal lever. The articulated pedal has a first pedal section pivotally supported on vehicle body structure and connected to a brake actuator cable. A second section is pivotally connected to the first section and is constructed to swing through an arc whereby the effective length of the lever arm between the pivot and the pedal pad is increased during a brake application.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A variable ratio pedal assembly comprising a first pedal section, pivot means constructed to support said first pedal section on a support member, an actuator connected to said first pedal section, said first pedal section being displaceable between first and second positions, releasable ratchet means engaging said first section and constructed to retain said first section in its second position, a second pedal section pivotally connected to said first pedal section, said second pedal section having an operator engaging portion, said second pedal section being angularly displaceable from a first position to a second position relative to said first pedal section whereby the length of the lever arm from said pivot means to said portion is increased and the mechanical advantage ratio of said pedal assembly is correspondingly increased.
Claim 2
Dependent Claim
129 words
A variable ratio pedal assembly comprising a first pedal section, pivot means constructed to support said first pedal section on a support member, an actuator connected to said first pedal section, said first pedal section being displaceable between first and second positions, releasable ratchet means engaging said first section and constructed to retain said first section in its second position, a second pedal section pivotally connected to said first pedal section, said second pedal section having an operator engaging portion, said second pedal section being angularly displaceable from a first position to a second position relative to said first pedal section whereby the length of the lever arm from said pivot means to said portion is increased and the mechanical advantage ratio of said pedal assembly is correspondingly increased.
Claim 3
Dependent Claim
125 words
