Abstract: Tonneau cover for mounting to a pickup truck having a cargo bed has a top panel and a bottom panel, wherein the bottom panel includes opposing arrays of upwardly extending projections having flat coplanar upper surfaces with the arrays divided by a beam feature that extends in a front to rear direction of the cover. The beam feature itself may include a series of upwardly extending projections having flat coplanar upper surfaces, which, advantageously, are elongate along the front to rear direction.

Abstract: A running board for a passenger car or light truck is assembled from an upper molded thermoplastic section or component having a Class A automotive finish and a lower component or section having reinforcing ribs and mounting brackets. The upper section includes three layers: a paint film having a Class A automotive finish, a thin layer of thermoplastic polyolefin (TPO) and a thick layer of polypropylene. The lower section is homogeneous and may be a plastic such as TPO, polypropylene or high-density polyethylene (HDPE), for example, which may contain chopped, randomly oriented glass reinforcing fibers. The two sections are secured to one another about their peripheries by autogenous bonding.
