Abstract
Abstract The present invention discloses an adjustable linkage mechanism adapted for use with foot-operated pedals, i.e., brake, accelerator and clutch, of a motor vehicle. The spacing between the seat of a motor vehicle and the pedals may be varied to suit the requirements of an individual operator through use of an actuator mechanism operatively connected between the pedal arm and the associated linkage mechanisms. Basically, the invention provides a powered means for automatically lengthening or shortening the associated linkage to pivot the pedal either toward or away from the seat to vary the spacing therebetween.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
An adjustable member for an operating pedal of an automotive vehicle, said operating pedal including an arm member pivotally mounted about an axis and linkage means connected by said adjustable member to said arm member between said axis and said pedal, the improvement in said adjustable member comprising: a housing adapted for connection to said arm member; a screw mounted in said housing extending outwardly therefrom connected to said linkage; a gear having an internally threaded hub portion rotatably supported in said housing threadably engaging said screw; and reversible drive means connected to said gear to rotate same to extend and retract said screw to vary the length of said linkage and thereby urge said pedal to pivot about said axis.
Claim 2
Dependent Claim
121 words
An adjustable member for an operating pedal of an automotive vehicle, said operating pedal including an arm member pivotally mounted about an axis and linkage means connected by said adjustable member to said arm member between said axis and said pedal, the improvement in said adjustable member comprising: a housing adapted for connection to said arm member; a screw mounted in said housing extending outwardly therefrom connected to said linkage; a gear having an internally threaded hub portion rotatably supported in said housing threadably engaging said screw; and reversible drive means connected to said gear to rotate same to extend and retract said screw to vary the length of said linkage and thereby urge said pedal to pivot about said axis.
Claim 3
Dependent Claim
34 words
