Automatic adjustable brake, clutch and accelerator pedals

摘要

An adjustable control pedal for a motor vehicle includes a link having an inclined slot formed therein, a screw supported by the link, a motor operatively connected to the screw to selectively rotate the screw about a central axis, and a nut threadably engaging the screw and adapted to move axially along the screw upon rotation of the screw. A pedal aim includes upper and lower pedal arms operatively connected for extension and retraction of the lower pedal arm relative to the upper pedal arm. The upper pedal arm is pivotally connected relative to the link. The lower pedal arm has a pedal at a lower end and a pin extending into the inclined slot. The pin is operatively connected to the nut so that the pin moves along the slot as the nut travels along the screw. The pedal arm rotates relative to the link and the lower pedal arm extends or retracts relative to the upper pedal arm as the pin moves along the inclined slot such that the pedal moves along a generally linear and horizontal path upon rotation of the screw. A second embodiment of the invention is disclosed which includes a link having first and second arcuate and inclined slots formed therein. A one-piece pedal arm is operatively connected to the nut. The pedal arm has a pedal at a lower end and first and second pins extending into the first and second inclined slots respectively so that the first and second pins move along the first and second slots respectively as the nut travels along the screw. The pedal arm rotates relative to the link as the first and second pins move along the first and second slots respectively such that the pedal moves along a generally linear and horizontal path upon rotation of the screw.
