Abstract

Abstract A mechanism for adjusting the fore and aft positions of motor vehicle pedal assemblies is provided. The assembly includes a pair of parallel, threaded shafts, each of which is connected to a gear assembly for simultaneous rotation. A cross rod is threadably mounted to each shaft and one or more pedal assemblies are pivotably mounted to the cross rod. The pedal assemblies and cross rod move in a direction which is parallel to the threaded shafts upon rotation of these shafts. A pulley assembly is also threadably mounted to one of the shafts and moves in the same directions as the cross rods during shaft rotation. The pulley cable is connected at one end to an accelerator pedal assembly and at the opposite end to the vehicle throttle. An elongate housing is connected to the booster input for the vehicle braking system while a threaded rod extending therefrom is connected to a brake pedal assembly. The housing is rotated in unison with the threaded shafts, thereby causing the threaded rod to move in the same direction as the brake pedal assembly.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 106 words
A pedal assembly for a motor vehicle comprising a support, a threaded shaft, pedal lever mounting means threadably mounted to the threaded shaft, a pedal lever pivotably mounted on the pedal lever mounting means, and an actuator, characterized by the actuator having an elongate threaded bore, a threaded rod connected to the pedal lever and engaged within the bore, and power means operatively connected to the threaded shaft and the actuator for rotating the shaft and the actuator to move the pedal lever mounting means and the threaded rod relative to the support while maintaining the angular orientation of the pedal lever relative to the support.
Claim 2
Dependent Claim 106 words
A pedal assembly for a motor vehicle comprising a support, a threaded shaft, pedal lever mounting means threadably mounted to the threaded shaft, a pedal lever pivotably mounted on the pedal lever mounting means, and an actuator, characterized by the actuator having an elongate threaded bore, a threaded rod connected to the pedal lever and engaged within the bore, and power means operatively connected to the threaded shaft and the actuator for rotating the shaft and the actuator to move the pedal lever mounting means and the threaded rod relative to the support while maintaining the angular orientation of the pedal lever relative to the support.
Claim 3
Dependent Claim 108 words
The pedal assembly of claim 1, further characterized by a second threaded shaft operatively connected to the power means, second pedal lever mounting means threadably mounted to the second shaft, a second pedal lever pivotably mounted to the second mounting means, a pulley, pulley mounting means threadably mounted on the second shaft, an actuator cable extending about the pulley and having one end secured to the second pedal lever such that rotation of the second shaft by the power means moves the second pedal lever mounting means and the pulley mounting means relative to the support while maintaining the angular orientation of the second pedal lever relative thereto.
Claim 4
Dependent Claim 44 words
The pedal assembly of claim 2, further characterized by a cross rod interconnecting the first and second pedal lever mounting means to ensure translation of these mounting means along the axes of the threaded shafts during rotation of the shafts by the power means.
Claim 5
Dependent Claim 70 words
The pedal assembly of claim 3, further characterized by a gear mounted on each of the threaded shafts and on the actuator, a drive motor, and drive belt means interconnecting the gears and the motor to enable synchronized concurrent rotation of both threaded shafts and the actuator to ensure that both pedal levers maintain their angular orientation during movement thereof relative to the support upon actuation of the drive motor.
