POLYMER REINFORCED METALLIC ROOF BOW

摘要

A roof bow (22) reduces noise and vibration of a motorized vehicle and includes a body having a length and two ends spaced apart from each other. The body also includes a metal and has thickness from about 0.25 mm to about 2 mm substantially along the length. Moreover, the body defines a base and first and second edges extending from the base. Each of the base and the first (34) and second (36) edges extend substantially along the length between the ends of the body. The first and second edges are each disposed transverse to the base and laterally spaced apart from each other substantially along the length. The roof bow also includes a plurality of ribs. The plurality of ribs (44) have a thickness from about 0.5 mm to about 5 mm and include a polymer. The plurality of ribs is disposed between the first and second edges and coupled to the body.
