Abstract

An adjustable pedal that includes a first body with a shoe, a second body pivotable about a shaft, the first body being movably coupled with respect to the second body, a third body being pivotable with respect to the second body and movably coupled with respect to the first body, the third body being coupled to an actuator through a coupling, and a control device suitable for adjusting the position of the pedal. The first body and the second body are telescopically coupled to one another, the control device controlling the distance between the rotating shaft and the coupling by moving the three bodies relatively to one another, keeping the ratio of the distance between the shaft and the shoe and the distance between the shaft and the coupling substantially constant.
