A mechanism connecting a rate control with a brake control for preventing the rate control from being shifted from a non-driving mode to a driving mode when the brake control means is in its parked mode, including a rod-like member having an offset portion biased to block an accelerator arm of the rate control, and a cam member in contact with the offset portion for allowing the offset portion to shift to its blocking position when the brake control is shifted to the parked mode, and for shifting the offset portion to a position whereat the accelerator arm is free to shift between the driving and non-driving modes when the brake control is in the unbraked mode.

A mechanism for preventing a drive means of a powered vehicle from being shifted to a driving mode when in a parked mode, comprising: shiftable rate control means for shifting the vehicle between driving and non-driving modes, said rate control means further comprising: a first foot actuated pedal, a shaft coupled with the first foot actuated pedal for shifting therewith, an arm member fixed to the shaft for shifting therewith, a linkage coupled with the arm member and the drive means for transferring motion of the arm member and shaft to a vehicle drive means for selectively adjusting the rate at which the vehicle is driven, brake control means for braking the vehicle, and adapted for being shifted between unbraked, braked, and parked modes, said brake control means further including a second foot actuated pedal and a U-shaped portion having end portions, means connecting the rate control means to the brake control means for preventing the rate control means from being shifted from the non-driving mode to a driving mode when the brake control means is in its parked mode, said connecting means further including: a cam member coupled with one end of the U-shaped portion for shifting with the second foot control pedal, an accelerator arm member coupled with the driving control means for shifting therewith, a rod-like member shiftable about a longitudinal axis defined by a portion of the rod-like member, said rod-like member having a portion offset from the axis and biased by a spring to a position whereat the accelerator arm is blocked from shifting to a driving mode, said cam member being in contact with the offset portion for shifting the offset portion to a non-blocking position whereat the accelerator arm is free to shift between the driving and non-driving modes when the brake control means is in the unbraked mode, said cam member also allowing the offset portion to shift to its blocking position when the brake control means is shifted to the parked mode.
