Abstract
Embodiments of an unpowered pedal assist device are provided for use in conjunction with a vehicular control pedal movable between a non-depressed position and a depressed position. In one embodiment, the unpowered pedal assist device includes a multi-bar linkage and at least one resilient element coupled to the multi-bar linkage. The multi-bar linkage is configured to be coupled to the vehicular control pedal and, when so coupled to move from a start position to a finish position as the vehicular control pedal moves from the non-depressed position to the depressed position. The at least one resilient element is configured to bias the multi-bar linkage: (i) toward the start position over an initial range of travel of the vehicular control pedal, and (ii) toward the finish position over a primary range of travel of the vehicular control pedal.
