ABSTRACT:
A plastic pedal for a motor vehicle (e.g. a clutch pedal), has a stepping plate portion at the front end of the pedal arm and a spring lever with bearing bores at a rear end. The pedal arm consists of a hollow profile having a rectangular cross-section and is provided with walls 15, 17 and 24 of approximately the same thickness and constructed to have smooth surfaces on the inside and on the outside. This type of a pedal has a low weight, takes up little space and has considerably stiffness, whereby relatively high torsional and bending stress can be absorbed.
