Abstract

A locationally adjustable pedal is provided for providing a force input to an automotive vehicle control. The adjustable pedal includes a crossbar having a rotational axis fixed with respect to the vehicle, an idler link having first and second ends, the first end being angularly fixed with respect to the crossbar, a top link having first and second ends with the first end pivotally connected with the crossbar with a pivotal axis generally coterminous with the rotational axis of the crossbar, a rear link with first and second ends with the first end pivotally connected to the top link second end, a pedal link pivotally connected with the second ends of the idler and rear links, the pedal link having a surface for operator contact, a rod link having a first end pivotally connected to the crossbar with a pivotal axis coterminous with the crossbar rotational axis, the rod link being angularly fixed with respect to the top link and the rod link having at a second end a pivotal connection with respect to the control rod, and a motor or hand wheel to adjust and fix the rotational position of the crossbar.

Claims

1. A locationally adjustable actuator for providing a force input to a rod operatively associated with an automotive vehicle control, the actuator in combination comprising:

a crossbar having a rotational axis fixed with respect to the vehicle;

an idler link having first and second ends, the first end being angularly fixed with respect to the crossbar;

a top link having first and second ends with the first end pivotally connected with the crossbar with a pivotal axis generally coterminous with the rotational axis of the crossbar;

a rear link with first and second ends with the first end pivotally connected to the top link second end;

a pedal link pivotally connected with the second ends of the idler and rear links, the pedal link having a surface for operator contact;

a rod link having a first end pivotally connected to the crossbar with a pivotal axis coterminous with the crossbar rotational axis, the rod link being angularly fixed with respect to the top link and the rod link having at a second end a pivotal connection with respect to the control rod; and

means to adjust and fix the rotational position of the crossbar.

2. An actuator as described in claim 1 further including spring means biasing the rod link to a retracted position.

3. An adjuster as described in claim 1 further including power means to adjust the rotational position of the crossbar.

4. An actuator as described in claim 1 wherein in any position the pedal link rotates in a constant radius upon input by the operator upon the surface for operator contact.

5. An actuator as described in claim 4 wherein the idler link, top link, pedal link and rear link form a parallelogram.

6. An actuator as described in claim 1 wherein said crossbar is torsionally associated with a first gear which is driven by a worm gear to provide the means to adjust and fix the rotational position of the crossbar.

7. An actuator as described in claim 1 for a plurality of vehicle operator controls with each actuator acting independent each actuator having the elements of idler, rear, top, pedal and rod links on a common crossbar independently provided for an individual input to a vehicle control, such pedals being positionally adjusted in unison upon the adjustment of the rotational position of the crossbar.

8. A powered locationally adjustable pedal for providing a force to an input rod operatively associated with a vehicle control, the locationally adjustable pedal in combination comprising:

a crossbar having a rotational axis fixed with respect to the vehicle and having connected at its end a first gear;

an idler link having first and second ends, the first end being angularly fixed with respect to the crossbar;

a top link having a first and second ends with the first end connected along a pivotal axis with the crossbar coterminous with the crossbar rotational axis;

a rear link with first and second ends with the first end pivotally connected to the top link second end;

a pedal link pivotally connected with the second ends of the idler and rear links, forming a parallelogram with the idler, rear, top and pedal links having a surface for contact with the foot of the vehicle operator;

a rod link having a first end pivotally connected with the crossbar along the crossbar rotational axis, the rod link being angularly fixed with the top link and the rod link having a second end for pivotal connection with the rod of the vehicle control;

a worm gear threadably associated with the first gear;

means to power the worm gear to adjust the position of the pedal and at the same time in all adjusted positions providing a constant radius of rotation when using the pedal to activate the vehicle control; and

means to bias the rod link to a retracted position.

9. A locationally adjustable pedal as described in claim 8 further including a second locationally adjustable pedal for second vehicle control with an associated input rod and a second set of idler, top, pedal, read and rod links connected in a manner similar as that previously described and providing an independent input to the second vehicle control, however, the second pedal being locationally adjusted simultaneously upon rotation of the crossbar.
