Abstract

A high strength polymeric injection molded running board for an automotive vehicle is provided including a longitudinal base portion with an upper first surface and a lower second surface opposite the first surface, the upper surface supporting a foot of a vehicle occupant entering or exiting the vehicle. The running board also includes grip ridges integrally molded with the base portion on the first surface to increase the frictional interface between the first surface and the foot of the vehicle occupant entering or exiting the vehicle. The grip ridges have a crown region and an incline portion connecting the crown region with the first surface. The running board also includes reinforcing ribs for strengthening the base portion, the ribs extend from the base portion second surface and are joined to the second surface generally opposite the incline portion of the grip ridges.
