Abstract

An adjustable pedal mechanism for automotive vehicles utilizes a slave lever pivoted on a conventionally located laterally extending front pivot and actuated by a pedal lever on a parallel rear pivot located behind and below the front pivot. The levers are connected by an adjustable link lying generally parallel with the plane of the front and rear pivots to form a parallelogram linkage with the link side being of variable length to vary the initial angular position of a foot pedal at the lower end of the pedal lever. The slave lever connects with an actuator rod for actuating a vehicle device such as a brake or clutch and is applied by forward motion of the foot pedal acting through the pedal lever and adjustable link to the slave lever which moves the actuator rod. The lowered rearward location of the pedal lever allows a greater variation of the pedal position without excessively raising the pedal height while the parallelogram linkage arrangement maintains pedal actuating travel essentially constant at all locations within the range of adjustment positions. A preferred embodiment includes powered adjustment of a ballscrew for adjusting the link.
