ABSTRACT:
An adjustable pedal mechanism for automotive vehicles includes a pivoting presenter arm with a swinging lower end that provides a pivot for a pedal actuating mechanism. A link connecting the actuating pedal with the operated device, such as an accelerator throttle or power control cable, extends essentially parallel to the presenter arm. the link has a length equal to that of the presenter arm so that pivoting of the presenter arm to move the pedal pivot point forward or back causes an equivalent pivoting motion of the link and thereby maintains the pedal attitude constant over a substantial range of adjustment positions. By making the presenter arm of substantial length and limiting its angular adjustment motion on either side of a vertical line, the height of the pedal above the vehicle floor is maintained relatively constant over the total range of adjustment of the pedal position.
