Abstract

A pedal adjuster for electronic throttle control includes a pedal arm and support arm pivotally mounted to a bracket. An electronic throttle control unit is mounted to the bracket at the pivot point of the pedal arm assembly. A screw rod drive mechanism extends in a space formed between the support arm and pedal arm to adjustably position the pedal arm with respect to the support arm. The pedal arm carries an elongated curved pedal. Depression of the pedal pivots the pedal arm assembly to turn a blade connected to the ETC unit to generate a signal indicative of the position of the pedal arm.

Claims

1. An adjustment assembly for adjusting the position of a pedal arm in a vehicle, said adjustment assembly comprising:

a support bracket mounted to said vehicle;

a support arm having one end pivotally mounted to said bracket;

a pedal arm pivotally mounted to another end of said support arm;

an adjustment mechanism extending between said support arm and said pedal arm, said adjustment mechanism having a screw rod attached to one of said pedal arm and said support arm to selectively position the pedal at a desired position between a retracted position and an extended position; and

an electronic control mounted to said bracket, said electronic control providing a signal indicative of a position of said arm assembly.

2. The adjustment assembly of claim 1 wherein said support arm has a portion extending in a direction outwardly from said bracket over said adjustment mechanism.

3. The adjustment assembly of claim 2 wherein said pedal arm has an upper portion and a lower portion which extends from said upper portion in a direction towards said bracket and under said adjustment mechanism.

4. The adjustment assembly of claim 1 further comprising a motor mounted to said bracket and a drive cable connecting said motor to said adjustment mechanism.

5. The adjustment assembly of claim 1 wherein said support arm includes a vertically extending portion and said pedal arm has an upper portion which is substantially parallel to said vertically extending portion of said support arm when said pedal arm is in said retracted position.

6. The adjustment assembly of claim 5 wherein said adjustment mechanism extends between said vertically extending portion of said support arm and said upper portion of said pedal arm.

7. An adjustment assembly for adjusting the position of a pedal arm in a vehicle, said adjustment assembly comprising:

a support bracket mounted to said vehicle;

a support arm having one end pivotally mounted to said bracket, said support arm having a lower portion and an upper portion extending in a direction outwardly from said bracket;

a pedal arm pivotally mounted to another end of said support arm, said pedal arm having a lower portion which extends in a direction towards said bracket;

an adjustment mechanism extending between said support arm and said pedal arm, said adjustment mechanism having a screw rod attached to one of said pedal arm and said support arm to selectively position the pedal at a desired position between a retracted position and an extended position, said adjustment mechanism extending between said upper portion of said support arm and an upper portion of said pedal arm; and

an electronic control mounted to said bracket, said electronic control providing a signal indicative of a position of said pedal arm.

8. The adjustment assembly of claim 7 further comprising a motor mounted to said bracket and a drive cable connecting said motor to said adjustment mechanism.
