  • Patent number: 8152187
    Abstract: A roll formed step rail for a vehicle comprises an elongated rail body having two opposing edges which define a longitudinal channel. The channel receives a pinch clamp which is wider than the channel and has a fastening hole and an alignment means. The rail body is lowered onto the mounting surface of a mounting bracket adapted for rigid connection to a vehicle. The mounting surface defines another fastening hole and another portion of the alignment means. A fastener draws the pinch clamp and the mounting surface toward opposite sides of the opposing edges of the rail body. Because the pinch clamp spans the width of the channel and is aligned properly relative to the mounting surface, the rail body is secured between the clamp and the mounting surface by the tightened fastener.

  • Patent number: 7946604
    Abstract: A roll formed step rail for a vehicle comprises an elongated rail body including a continuous rail wall of substantially uniform thickness. The rail wall describes a continuous cross-sectional profile between two elongated free edges, the cross-sectional profile of the rail being substantially uniform along the length of the rail body. The cross-sectional profile of the rail body includes a relatively flat top portion disposed between a substantially semi-circular front curved portion and a substantially quarter-circular rear curved portion. A rear mounting lip extends forward from the rear curved portion to one of the elongated free edges. A front mounting lip extends upward and then rearwards from the front curved portion to another of the elongated free edges. The elongated free edges are generally in line with one another, but spaced apart to define a longitudinal channel therebetween having a predetermined width. The rail body is formed from a sheet of material by a process of roll forming.
