Abstract

An adjustable control pedal for a motor vehicle includes a pivotable upper pedal arm having a slot formed therein, a link pivotable relative to the upper pedal arm, and a lower pedal arm having an upper end pivotably connected to the link and a lower end carrying a pedal. A nut is pivotally connected to the link such that the link pivots relative to the upper pedal arm upon movement of the nut along a drive screw. A pin is connected to the lower pedal arm and laterally extends into the slot such that the pin moves along the slot upon pivotal movement of the link. Also disclosed is a control pedal having a drive block or a pair of spaced apart pins located in a single slot of the upper pedal arm.

Claims

1. An adjustable control pedal comprising, in combination:

a pivotable upper arm having a slot formed therein;

a lower arm having a lower end carrying a pedal and operatively connected to the upper arm for selected movement relative to the upper arm;

a drive assembly operatively connected to the lower arm to selectively move the lower arm relative to the upper arm;

a guide block secured to the lower arm and laterally extending into the slot;

wherein the guide block moves along the slot upon selected movement of the lower arm relative to the upper arm by the drive assembly; and

wherein the slot is arcuate and the guide block has arcuate upper and lower surfaces engaging edges of the slot.

2. The adjustable control pedal according to claim 1, wherein the drive assembly includes a screw carried by the upper arm, a nut threadably engaging the screw and adapted to move axially along the screw upon rotation of the screw, and a motor operatively connected to the screw to selectively rotate the screw, and wherein the nut is secured to the lower arm.

3. The adjustable control pedal according to claim 2, wherein the nut is secured to the guide block.

4. The adjustable control pedal according to claim 1, wherein the guide block is formed separate from the lower arm and is attached to the lower arm.

5. The adjustable control pedal according to claim 4, wherein the guide block has at least one pin extending into an opening of the lower arm to rigidly attach the guide block to the lower arm.

6. The adjustable control pedal according to claim 1, wherein the lower arm is supported by the upper arm only through the guide block.
