A pedal assembly including a pedal support and a pedal member rotatably coupled to the pedal support to allow pivotal movement of the pedal member about a pivot axis. The pedal assembly further includes a friction member having a bearing surface, and a clamp member engaged with the pedal member and having an engagement surface abutting the bearing surface of the friction member to define at least two separate and distinct surface contact regions. The pedal assembly also includes a biasing member arranged to bias the clamp member to provide frictional engagement along the separate and distinct surface contact regions to resist pivotal movement of the pedal member. In one embodiment, the clamp member is engaged with the pedal member by a sliding pivot configured to allow the clamp member to be pivotally and slidably displaced relative to the pedal member during pivotal movement of the pedal member.

Integrated pedal assembly having a hysteresis mechanism

A pedal assembly for use in association with a vehicle includes a pedal support adapted for mounting to the vehicle. The pedal support includes a pivot shaft extending along a pivot axis and having an outer bearing surface. A pedal arm is rotatably engaged to the pivot shaft to allow pivotal movement of the pedal arm about the pivot axis. A clamp arm is pivotally coupled to the pedal arm and has a compression surface. A biasing member is engaged between the pedal support and the clamp arm and is arranged to apply a biasing force to the clamp arm to pivot the clamp arm relative to the pedal arm and toward the pivot shaft. Application of an activation force onto the pedal arm pivots the pedal arm about the pivot axis, which in turn increases the biasing force applied to the clamp arm by the biasing member to correspondingly increase frictional engagement between the compression surface of the clamp arm and the bearing surface of the pivot shaft to provide increased resistance to further pivotal movement of the pedal arm.
