Patent ID: 6918318

Claim:
A variable ratio brake pedal assembly for varying the pedal ratio during a pedal stroke comprising: a support bracket having a mounting face and two spaced apart side arms extending from opposing edges of said mounting face; a pedal arm, wherein an upper end of said pedal arm is pivotally mounted to said support bracket at a first pivot point and a pedal pad is mounted to a lower end of said pedal arm; a pedal link having a first end and a second end, wherein said first end is pivotally connected to said pedal arm at a third pivot point; a brake booster link having a first end and a second end, wherein said first end of said brake booster link is pivotally mounted to said second end of said pedal link at a fourth pivot point and said second end of said brake booster link is pivotally mounted to said support bracket at a second pivot point; and a brake booster rod attaching means located on the brake booster link at a fifth pivot point, wherein said fifth pivot point is located on said brake booster link between said second pivot point and said fourth pivot point, and a first distance between said second pivot point and said fifth pivot point is less than a second distance between said second pivot point and said fourth pivot point such that the pedal ratio varies nonlinearly during the pedal stroke.
