  • Patent number: 9513656
    Abstract: A vehicle pedal resistance and kickdown assembly including a plunger moveable in a housing between first and second positions. The plunger defines a recess for a rod, A first spring in the housing biases the plunger in the first position. A second spring retains the rod in the plunger recess in the first position. In one embodiment, the recess in the plunger is an elongate recess in a flat front face of the plunger. In one embodiment, the housing defines an aperture in a to or bottom wall of the housing that has a length greater than the length of the second spring and the second spring is inserted lengthwise into the housing through the aperture. In one embodiment, the second spring is retained in a clip in the housing.
