Abstract

A vehicle pedal assembly comprising a pedal including a pedal stub arm having a metal pedal arm molded into a plastic stem with inserts molded therein and an actuator bar coupled to the stem of the pedal. Fasteners extend through the actuator bar and into the inserts in the stem for securing the actuator bar to the pedal. The actuator bar is adapted to exert an active force against the pedal. In one embodiment, both the pedal arm and the actuator bar include one or more bends defined therein. The pedal arm has a length and shape dependent upon the distance and position of the floor or pedal pad relative to the pedal. The actuator bar has a length and shape dependent upon the distance and position of the pedal relative to an actuator arm.

Claims

1. A vehicle pedal assembly comprising:

a pedal housing;

a pedal including a pedal arm extending outwardly from the pedal housing and a pedal stub extending into the pedal housing; and

an actuator bar including a proximal end coupled to the pedal stub and adapted for application of an active force on the pedal;

the pedal stub including a drum that extends into the pedal housing and is adapted for rotation to the pedal housing and a stem unitary with the drum that extends outwardly from the pedal housing, the proximal end of the actuator bar being coupled to the stem of the pedal stub; and

the stem including a pair of threaded inserts molded therein, the proximal end of the actuator bar including a pair of through-holes, and further including a pair of fasteners extending through the pair of through-holes and the pair of inserts respectively for coupling the actuator bar to the pedal.

2. The vehicle pedal assembly of claim 1, wherein the actuator bar is made of metal and has a length and bends defined therein and dependent upon the predetermined required distance and position between the pedal and an actuator arm.

3. An active force vehicle accelerator pedal assembly comprising:

a pedal housing;

a pedal extending into the pedal housing, the pedal including a pedal arm molded into a stem, the stem including at least a first insert molded therein;

an actuator bar defining at least a first through hole, the actuator bar being abutted against the stem with the at least first through hole in alignment with the at least first insert in the stem of the pedal; and

at least a first fastener extending through the at least first through hole in the actuator bar and the at least first insert in the stem for coupling the actuator bar to the pedal, the actuator bar being adapted for application of an active force against the pedal.

4. The active force vehicle accelerator pedal assembly of claim 3, wherein a pair of inserts are molded into the stem of the pedal, a pair of through holes are defined in the actuator bar, and a pair of fasteners extend through the pair of through holes and the pair of inserts respectively.

5. The active force vehicle accelerator pedal assembly of claim 3, wherein the actuator bar includes a plurality of bends defined therein, the number and orientation being determined by the required distance and position between the pedal and an actuator arm.

6. The active force vehicle accelerator pedal assembly of claim 3, wherein the pedal arm includes a plurality of bends defined therein, the number and orientation being determined by the required distance and position of the pedal relative to a floor of a vehicle.

7. An active force vehicle accelerator pedal assembly comprising:

a pedal housing defining an interior;

a pedal including a pedal arm molded into a pedal stub, the pedal arm including one or more bends defined therein, the pedal stub including a stem and a drum unitary with the stem, the drum extending into the interior of the pedal housing and the stem extending outwardly from the pedal housing, the stem including a plurality of inserts molded therein;

an actuator bar including a proximal end defining a plurality of through holes and one or more bends defined therein, the proximal end of the actuator bar abutting against the stem of the pedal stub with the plurality of through holes in alignment with the plurality of inserts in the stem of the pedal; and

a plurality of fasteners extending respectively through the through holes in the actuator bar and into the plurality of inserts in the stem of the pedal stub for coupling the actuator bar to the pedal, the actuator bar being adapted to exert an active force against the pedal.

8. The active force vehicle accelerator pedal assembly of claim 7, wherein both the pedal arm and the actuator bar are made of metal and the pedal housing and the pedal base are made of molded plastic material.

9. The active force vehicle accelerator pedal assembly of claim 7, wherein the number and orientation of the bends in the pedal arm and the actuator bar is determined by the required distance and location of the pedal relative to a vehicle and the distance and location of the pedal relative to an actuator arm of the vehicle respectively.
