Abstract
Abstract 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.

Claim 2
Dependent Claim
133 words
A control pedal apparatus for a motor vehicle comprising: A) a mounting bracket adapted to be mounted on the fire wall of the vehicle; B) a pedal assembly; C) pivot means mounting the upper end of said pedal assembly for pivotal movement on said bracket about a pivot axis; D) a pedal pad mounted on the lower end of said pedal assembly; E) attachment means on said pedal assembly defining an attachment point for attachment of a control member for operation of a control system of the vehicle in response to pivotal movement of said pedal assembly upon the application of operator pressure to said pedal pad; and F) pedal adjustor means of operative to selectively move said pedal pad relative to said bracket without moving said attachment point relative to said bracket.
Claim 3
Dependent Claim
61 words
A control pedal apparatus according to claim 1 wherein: G) said pedal assembly includes a pedal arm and an adjustor member; H) said pedal pad is mounted on the lower end of said pedal arm; I) said attachment means is on said adjustor member; and J) said adjustment means comprises coacting means on said pedal arm and on said adjustor member.
Claim 4
Dependent Claim
70 words
A control pedal apparatus according to claim 2 wherein: K) said coacting means comprises 1) means mounting said pedal arm for sliding adjustment on said adjustor member, and 2) means operative to produce joint pivotal movement of said pedal arm and adjustor member about said pivot axis in response to operator pressure on said pedal pad in any position of sliding adjustment of said pedal arm on said adjustment member.
Claim 5
Dependent Claim
92 words
A control pedal apparatus according to claim 2 wherein: K) said coacting means comprises 1) a pair of spaced pins on said pedal arm, 2) a pair of parallel tracks on said adjustor member respectively slidably receiving said pins, 3) a nut carried by said pedal arm, and 4) a screw extending generally in the direction of said tracks, threadably engaging said nut, and precluded from axial movement so that rotation of said screw causes said pins to slide in said tracks to slidably adjust said pedal arm on said adjustor member.
