Electric adjustable pedal system with two-piece upper arm
First Claim
1. An adjustable control pedal comprising, in combination:
- a mounting bracket;
an upper arm having first and second generally planar members, said first and second members being generally parallel and spaced apart;
wherein the upper arm is pivotably attached to the mounting bracket;
a lower arm having a lower end carrying a pedal and an upper end extending between said first and second members and operatively connected to said upper arm for selected movement relative to said upper arm;
a drive assembly operatively connected to the lower arm to selectively move the lower arm relative to the upper arm;
wherein the drive assembly includes a drive screw carried by the upper arm and a nut operably connected to the lower arm and threadably engaging the drive screw to move axially along the drive screw upon rotation of the screw;
wherein the drive screw is located adjacent a side of the second member opposite the first member with the second member positioned between the drive screw and the first member; and
wherein the first and second generally planar members are secured together by at least one separate spacer pin extending between the first and second generally planar members.

Abstract
An adjustable control pedal for a motor vehicle includes an upper arm having first and second substantially parallel and spaced-apart members. The first and second members are rigidly connected together to prevent relative movement therebetween and each have first and second slots formed therein. A lower arm has a lower end carrying a pedal and an upper end extending between the first and second members. A first guide pin is secured to the lower arm and extends into the first slot of the first member and the first slot of the second member. A second guide pin is secured to the lower arm and extends into the second slot of the first member and the second slot of the second member he slots and the guide pins form a sliding two-pin four-slot connection between the upper and lower pedal arms. The guide pins preferably have flat or planar upper and lower engagement surfaces located within the slots. Preferably, polymer bushings are provided which encircle the guide pins within the slots and have flanges which extend between the upper and lower arms. A drive assembly is operatively connected to the lower arm to selectively move the lower arm relative to the first and second upper arms to adjust the position of the pedal relative to the operator of the motor vehicle.
