<p>A control pedal apparatus for adjusting a control pedal of a motor vehicle such for example as a brake pedal or an accelerator pedal. The mechanism includes a pedal arm (14f), an adjustor member (12), and a bracket (10) secured to the fire wall of the vehicle. The mechanism allows the position of the pedal pad (22) to be adjusted slidably on the adjustor member (12) without disturbing the position of the particular control element actuated by the pedal assembly, and selectively moves the pivot axis of the pedal assembly to maintain a fixed mechanical advantage of the pedal assembly irrespective of the position of adjustment of the pedal arm (14f) on the adjustor member (12). Coacting, intersecting slots (12d, 12e) in the adjustor member and pedal arm allow the pivot axis to selectively move during adjustment of the assembly and fix the position of the pivot axis in any adjusted position of the pedal arm so that the pedal assembly pivots positively about the instantaneous assembly axis in any adjusted position of the pedal arm. One disclosed embodiment is intended for control of the push rod of the brake master cylinder and another disclosed embodiment is intended to control the throttle cable of the throttle mechanism. In each case, the adjustment of the pedal arm is accomplished by the rotation of a screw (24) engaging a nut (14e) on the pedal arm with the screw being driven by a motor (26) mounted on the bracket of the pedal assembly.</p> |
