A pedal assembly including a bracket, a pedal lever pivotally mounted to
the bracket, a spring mounted to the bracket, and a cam pivotally mounted
to the bracket. The cam engages one end of the spring so as to load the
spring while the cam pivots. The cam has a pre-determined profile and the
pedal lever engages the cam profile to pivot the cam and load the spring
during the stroke of the pedal lever, thus enabling the assembly to
provide a pre-determined force versus stroke profile.
