Abstract

An adjustable control pedal apparatus is used in a motor vehicle. The pedal apparatus includes a pedal assembly mounted to a support bracket mounted to the vehicle by a pivot shaft. The pivot shaft contains a worm gear. The pedal assembly includes a pedal arm pivotally mounted to an inner arm. A jack screw extends between the inner arm and pedal arm. The jack screw has a pinion portion on one end which is driven by the worm gear of the pivot shaft. A threaded portion of the jack screw is threadably received in a slide block mounted to the pedal arm. Rotation of the pivot shaft by a motor correspondingly turns the jack screw to adjust the position of the pedal.

Claims

1. An adjustable control pedal apparatus for adjustably varying the position of a pedal with respect to a user in a vehicle, said apparatus comprising:

a bracket mounted to the vehicle;

a pivot shaft pivotally mounted to said bracket, said pivot shaft having a worm gear portion;

a pedal assembly pivotally mounted to said pivot shaft, said pedal assembly having a pedal arm pivotally connected to an inner arm;

a threaded member connected to said pedal arm;

a jack screw having a threaded portion and a pinion gear portion, said pinion gear portion meshingly connected to said worm gear portion of said jack screw, said threaded portion received in said threaded member;

a motor drivingly connected to said pivot shaft to rotate said shaft and said jack screw to vary the position of said pedal arm with respect to said inner arm.

2. The adjustable control pedal apparatus of claim 1, wherein said inner arm has at least one bearing supporting said jack screw.

3. The adjustable control pedal apparatus of claim 1, wherein said pedal arm has a pair of side walls and said threaded member is mounted for sliding movement between said pair of side walls.

4. The adjustable control pedal apparatus of claim 3, wherein each side wall has a longitudinal slot and said threaded member has a pair of pins mounted in each slot of said pair of side walls.

5. The adjustable control pedal apparatus of claim 1, wherein said motor is mounted to said bracket.

6. The adjustable control pedal apparatus of claim 1, wherein said pedal arm has a rear wall having an aperture for freely receiving said jack screw therethrough.

7. An adjustable control pedal apparatus for adjustably varying the position of a pedal with respect to a user, said apparatus comprising:

a bracket mounted to said vehicle;

a pedal assembly pivotally mounted to said bracket, said pedal assembly comprising a pedal arm pivotally mounted to an inner arm;

a threaded member mounted to said pedal arm;

a shaft having a worm gear portion mounted to said inner arm;

a jack screw having a pinion portion, said pinion portion in meshing contact with said worm gear portion of said shaft, said jack screw having a threaded portion received in said threaded member;

a motor for rotating said shaft and said jack screw to adjust the position of said pedal arm.

8. The adjustable control pedal apparatus of claim 7, wherein said inner arm has at least one bearing supporting said jack screw.

9. The adjustable control pedal apparatus of claim 7, wherein said pedal arm has a pair of side walls and said threaded member is mounted for sliding movement between said pair of side walls.

10. The adjustable control pedal apparatus of claim 9, wherein each side wall has a longitudinal slot and said threaded member has a pair of pins mounted in each slot of said pair of side walls.

11. The adjustable control pedal apparatus of claim 7, wherein said motor is mounted to said bracket.

12. The adjustable control pedal apparatus of claim 7, wherein said pedal arm has a front wall having an aperture for freely receiving said jack screw therethrough.

13. The apparatus of claim 7, wherein said shaft is mounted to said bracket.
