Abstract: A two piece pedal arm assembly which forms a shell forming an internal cavity is provided. The two shell piece pedal arm permits the ability to carefully control wall thicknesses. This permits the ability to provide the proper strength where needed in complex designs resulting in weight savings. Additionally, other components such as the bracket and cage for a ball and booster arm, pedal adjusters, and the like can be mounted within the shell thereby providing robust attachment and a more pleasing appearance.

Abstract: An electronically controlled floor mounted pedal assembly with a position sensor includes a base. A control arm is pivotally mounted to the base member at a control arm pivot axis, and a pedal arm is pivotally mounted to the base member at a pedal arm pivot axis. The control arm free end is positioned adjacent an inner surface of the pedal arm. A friction generating member mounted on the control arm free end contacts a pedal arm friction member positioned on the inner surface of the pedal arm to generate frictional hysteresis force. A spring positioned between the base member and the control arm free end initially biases the control arm against the pedal arm. A position sensor supported on the base member about the control arm pivot axis senses angular rotation of the control arm about the control arm pivot axis as the pedal arm rotates about the pedal arm pivot axis.

Abstract: A compact vehicle pedal includes a mounting bracket having a lower arm with guide slot. A swing plate having a mounting face and upper arm with guide slot is pivotally interconnected to a mounting bracket upper arm at a first axis by a pivot pin disposed within the swing plate guide slot, and the swing plate upper end has a first degree of freedom. An electronically controlled pedal arm assembly is mounted on the swing plate. A screw member connected to a drive apparatus has an end connected to the swing plate and operatively connected to the mounting bracket slot at the second axis, and the swing plate lower end has a second degree of freedom that is greater than the first. Activation of the drive apparatus displaces the screw member to pivotally constrain movement of the swing plate about the first axis and the second axis.

Abstract: An adjustable pedal includes a mounting bracket and guide housing having a gear sector formed therein. The gear sector pivots about a fixed pivot during adjustment, and the mounting bracket upper arm includes an arcuate slot having a radius of curvature centered at the fixed pivot. A swing plate is slidingly supported within the arcuate slot in the mounting bracket upper arm at a second non-fixed pivot point located radially inboard from the first pivot point. The swing plate includes a gear sector that cooperates with the guide housing gear sector. A pedal arm with pedal pad is attached to the swing plate. An adjustment mechanism adjusts the pedal pad position. The guide housing gear sector pivots about the fixed pivot, engaging the swing plate gear sector and varying the position of the non-fixed pivot within the slot in the mounting bracket arm, constraining travel of the pedal pad.

Abstract: An electronically controlled pedal assembly with hysteresis includes a mounting bracket and pedal arm and a pedal support arm extending therebetween. The pedal arm is pivotally mounted to the pedal support arm at a pedal arm pivot point. The pedal support arm is pivotally mounted to the mounting bracket at a pedal support arm pivot point. A hysteresis generating means is operatively supported by the support arm at the pedal support arm pivot point, and includes a torsion spring and a friction spacer having a cylindrical portion and an outer helical flange. The friction spacer is disposed within the torsion spring such that the outer flange of the friction spacer fits between the coils of the coil spring. Rotation of the support arm creates a frictional hysteresis force between the torsion spring and the friction spacer that is translated back through the pedal arm.

Abstract: An adjustable pedal assembly for a vehicle includes a mounting bracket having a mounting face and a pair of opposed upper arms. The assembly includes a first lever arm supported between the pair of mounting bracket upper arms at a first fixed pivot point. The assembly also includes a swing plate pivotally supported by the first lever arm at a second non-fixed pivot point located radially outboard from the first fixed pivot point, and having a mounting face, a pair of upper arms radially extending, a vertically extending lower arm and an outwardly extending pedal support arm. The assembly further includes a second lever arm pivotally attached to the swing plate lower arm at a third non-fixed pivot point at one end and another end pivotally attached to the mounting bracket at a fourth fixed pivot point. The assembly includes a pedal arm operatively attached to the swing plate with a pedal pad attached at a lower end.

Abstract: An electronically controlled pedal assembly with hysteresis includes a housing having a front wall and an arcuate friction wall having a radius of curvature centered on a pedal arm pivot point and extending from an edge of the front wall. The pedal assembly also includes a pedal arm rotatably supported at the pedal arm pivot point by a mounting means operatively connected to the housing, and a hysteresis generating means pivotally mounted to the pedal arm. The pedal assembly further includes a spring positioned between the housing and the hysteresis generating means, such that the spring biases the hysteresis generating means against the housing, so that depression of the pedal arm compresses the spring while generating an increasing frictional hysteresis force between the arcuate friction wall and the hysteresis generating means that is translated back through the pedal arm, and release of the pedal arm reduces the frictional hysteresis force.

Abstract: An adjustable pedal system for a vehicle having an adjustable pedal assembly with an interlock switch includes a pedal arm assembly pivotally mounted to a support bracket at a fixed pivot point. The system also includes a pedal adjustment switching means operable by a vehicle driver to actuate a pedal adjustment mechanism for selectively positioning the pedal arm assembly to locate the pedal pad with respect to the driver. The pedal adjustment mechanism is operatively connected to the pedal arm assembly and receives a signal from the pedal adjustment switching means to adjust the location of the pedal pad. The system further includes an interlock switch, wherein an interruption in electrical continuity within the system activates the interlock switch to discontinue power to the pedal adjustment mechanism to prevent further adjustment of the pedal pad by the pedal adjustment means.

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.
