Abstract An adjustable control pedal assembly for a motor vehicle. The pedal assembly includes an upper hub structure and a pedal arm extending downwardly from the hub structure and mounting the pedal pad. The hub structure is slidably mounted on a single hollow guide rod extending rearwardly from a transmission housing which in turn is rigidly secured to a pivot arm. The pivot arm is pivotally mounted to a bracket secured to the firewall of the vehicle. A nut is positioned slidably within the hollow guide rod and a screw shaft extends rearwardly from the transmission housing for threaded engagement with the nut. The upper end of the pedal arm extends upwardly through a slot in the bottom of the hub structure and through a slot in the bottom of the guide rod and the nut is positioned on the upper end of the pedal arm within the hub so that linear movement of the nut within the hollow rod as generated by rotation of the screw shaft results in forward and rearward movement of the pedal assembly along the guide rod. The screw shaft is driven by a transmission positioned in the transmission housing and the transmission is in turn driven by a cable driven by an electric motor mounted on the lower end of the pivot arm proximate the mounting location of the guide rod on the pivot arm.
An adjustable pedal apparatus for a vehicle comprising: a mounting structure adapted to be mounted on the vehicle; a guide rod extending in a cantilevered fashion from said mounting structure to a distal end; a screw shaft extending from said mounting structure and parallel to said guide rod; a pedal guide structure slidably disposed on said guide rod for sliding movement along said guide rod toward and away from said mounting structure; a threaded nut threadedly engaging said screw shaft and supported by said pedal guide structure; drive means for rotating said screw shaft to move said pedal guide structure along said guide rod; a pedal arm extending downwardly from said pedal guide structure; said apparatus characterized by said guide rod being circular in cross section and said pedal guide structure having a circular bore in close sliding engagement with said guide rod.
