Adjustable automobile pedal system

Abstract

An adjustment device for an automobile control pedal which is capable of pivotably adjusting the control pedal relative to a datum point, such as the eyelet of a cylinder pushrod. The adjustment device allows the control pedal to be optimally positioned to suit the needs of a particular driver. The preferred control pedal can be pivotably attached to a frame in any conventional manner, such as with a pivot pin. The adjustment device is mounted alongside the control pedal and to the pushrod eyelet without the need of additional support hardware other than a link for maintaining a predetermined distance between the pushrod eyelet and the pivot pin of the control pedal. Consequently, the adjustment device can be readily adapted to fit conventional control pedal assemblies without significant modification. The adjustment device includes a camming device which slidably abuts the pedal arm such that rotation of the camming device causes pivotable movement of the pedal arm relative to the datum point. The camming device axis of rotation is preferably maintained a predetermined distance from the pivot of the control pedal arm by a spacing device, such as a link. The adjustment device also includes a cam driving device for rotating the camming device about its axis of cam rotation to produce a corresponding displacement of the control pedal arm about the axis of arm rotation.
