Abstract
A brake pedal assembly includes a pedal arm formed from one-piece of aluminum bar stock which is pivotally mounted by a bushing holder fixed on the pedal arm by external upsetting. The pedal arm includes two integral projections which receive the foot pad plate that is secured on the pedal arm by staking of the integral projections. This enables the assembly of a brake pedal without welding of material and facilitates the use of aluminum material in fabricating the pedal arm.
Claims3
A brake pedal assembly comprising:
- a pedal arm with two projections formed as one-piece with the pedal arm;
- a plate capable of supporting a foot pad positioned over the projections and fixed thereon by staking of the projections;
- a brushing holder fixed on the brake pedal assembly by two beads formed by an external enlargement of the busing holder;
- and
- a bracket fixed in position on the brake pedal assembly by the busing holder wherein the bracket includes an opening which is received over the busing holder and an arm which is positioned against the pedal arm, the arm self-aligning the bracket on the brake pedal assembly.

A brake pedal assembly comprising:
- a pedal arm fabricated from a one-piece aluminum bar formed with an upper section and a lower section, the upper and the lower sections connected by an offset section;
- a backing arm formed as part of the lower section and bent to a position approximately 90 degrees relative to the lower section;
- wherein a portion of the lower section including the backing arm is formed with a cut-out with a first projection and a second projection extending from the backing arm and formed as part of the backing arm;
- wherein the upper section of the pedal arm includes a first opening;
- a cylindrical bushing holder received within the first opening and fixed therein by a first bead and a second bead;
- a bracket fixed against the pedal arm by the bushing holder, the bracket having a face, wherein the bracket is self-aligning in position by including a self-aligning arm that is positioned against the upper section of the pedal arm so that the face of the bracket is properly positioned;
- an output pin fixedly retained on the upper section by being positioned in a second opening wherein the output pin includes a head that is deformed to securely maintain the output pin in position;
- a plate received onto the first and second projections of the backing arm and nesting in the cutout wherein the projections are deformed so that a bead is formed on each of the projections to maintain the plate in position securely on the pedal arm wherein the backing arm provides a secure support across a substantial part of the plate;
- and
- a resilient foot pad positioned on the plate.
