Abstract: A multistage energy absorber device is provided that includes at least two generally tubular members. Each of the generally tubular members has a first end and a second end. The second generally tubular member is independent of the first generally tubular member and fits within the first generally tubular member. The first ends of the generally tubular members are substantially flush with each other, but the second end of the second generally tubular member protrudes sufficiently beyond the second end of the first generally tubular member to form a first deformation stage. The first and second generally tubular members extend coextensively sufficiently from the first ends of the first and second generally tubular members to the second end of the first generally tubular member to form a second deformation stage.

Abstract: An energy absorber device is provided that includes a generally cylindrical member defining an axis and having an outer surface. One or more axially-spaced, substantially annular members are operatively connected to the generally cylindrical member at the outer surface to create areas of stress concentration in the generally cylindrical member, such that deformation of the generally cylindrical member due to a sufficient force applied to the generally cylindrical member is initiated at the areas of stress concentration, with the areas of stress concentration being reinforced by the substantially annular members. The areas of stress concentration act as crush initiation features and are formed by the connection of the substantially annular members to the generally cylindrical member. Thus, expensive tooling, such as preformed dies, to form the initiation features in the generally cylindrical member is not required.

Abstract: A vehicle ditch molding for insertion and retention in a recess, such as a roof ditch, formed between a first vehicle body panel and a second vehicle body panel is disclosed. The vehicle ditch molding may include a head extending outward from a ditch molding centerline and configured to cover an opening to the recess, and a stem extending from the head along the ditch molding centerline and configured to be narrower than the opening to the recess. Also, the vehicle ditch molding may include a pair of wings extending outward from the stem, with each of the wings having an upper surface facing the head and a lower surface, with each having a wing lower notch extending into the wing lower surface defining an inner living hinge extending between the respective wing lower notch and the corresponding upper surface.
