Adjustable pedal system with misalignment sensor
First Claim
1. An adjustable pedal system comprising,a first pedal attached to a first moveable member of a first actuator for adjusting position of the first pedal in a fore and aft direction, a second pedal attached to a second moveable member of a second actuator for adjusting position of the second pedal in the fore and aft direction, motor means drivingly connected to the first actuator and the second actuator for driving the first and the second moveable members in the fore and aft direction, the first actuator being driven via a first drive member and the second actuator being driven via a second drive member, means to maintain the position of the first pedal with respect to the position of the second pedal in the fore and aft direction within a predetermined limit in the event that one of the first and second drive members breaks while another of the first and second drive members remains intact during pedal adjustment.

Abstract
An adjustable pedal system has a first pedal pivotally attached to the translatable nut of a first jack screw actuator for adjusting the fore and aft position of the first pedal and a second pedal pivotally attached to the translatable nut of a second jack screw actuator for adjusting the fore and aft position of the second pedal and a third pedal pivotally attached to the translatable nut of a third jack screw actuator for adjusting the fore and aft position of the third pedal. An electric motor drives the translatable nuts fore and aft, and a motor control switch assembly controlled by the fore and aft movements of two of the nuts maintain alignment of the three pedals. A memory circuit may be incorporated into the system for moving the pedals to a preselected adjusted position or indicating the preselected adjusted position. The memory circuit may be separate or incorporated in a seat memory module.
