Abstract
Abstract A folding riding vehicle, such as a tricycle, feature a front frame element to which a front wheel and handlebars are mounted. A front bracket is attached to the front frame element and a seat bracket, to which a seat is mounted, is pivotally attached to the front bracket. A rear frame element has a pair of rear wheels mounted thereto and is attached to a rear bracket. The rear bracket is also pivotally mounted to the front bracket. The rear seat bracket features a pin that engages slots in the seat bracket. As a result, the seat bracket pivots with respect to the front bracket as the rear frame element is pivoted relative to the front bracket as the riding vehicle is moved between folded and unfolded configurations.
