  • Electronic throttle control with hysteresis device
    Patent number: 7337692
    Abstract: An electronically controlled pedal assembly with hysteresis includes a mounting bracket and pedal arm and a pedal support arm extending therebetween. The pedal arm is pivotally mounted to the pedal support arm at a pedal arm pivot point. The pedal support arm is pivotally mounted to the mounting bracket at a pedal support arm pivot point. A hysteresis generating means is operatively supported by the support arm at the pedal support arm pivot point, and includes a torsion spring and a friction spacer having a cylindrical portion and an outer helical flange. The friction spacer is disposed within the torsion spring such that the outer flange of the friction spacer fits between the coils of the coil spring. Rotation of the support arm creates a frictional hysteresis force between the torsion spring and the friction spacer that is translated back through the pedal arm.

  • Adjustable vehicle control pedals
    Patent number: 6453767
    Abstract: An adjustable control pedal apparatus is used in a motor vehicle. The pedal apparatus includes a pedal assembly mounted to a support bracket mounted to the vehicle by a pivot shaft. The pivot shaft contains a worm gear. The pedal assembly includes a pedal arm pivotally mounted to an inner arm. A jack screw extends between the inner arm and pedal arm. The jack screw has a pinion portion on one end which is driven by the worm gear of the pivot shaft. A threaded portion of the jack screw is threadably received in a slide block mounted to the pedal arm. Rotation of the pivot shaft by a motor correspondingly turns the jack screw to adjust the position of the pedal.
