Impact beam for car doors

Abstract

An impact beam for car doors is disclosed. This impact beam is reinforced at its central portion, and is improved in beam bracketing structure. The impact beam is also improved in bending strength and impact energy absorption capacity. In an embodiment, the impact beam consists of a longitudinal beam stepped at two positions to allow its central portion to be thicker than its opposite end portions. In another embodiment, the impact beam consists of a longitudinal base beam body, and a hollow reinforcing beam body having a length shorter than that of the base beam body and a sectional size larger than that of the base beam body, and fitted over a central portion of the base beam body. The impact beam further comprises a beam bracketing structure for fastening the opposite ends of the impact beam on a door panel. This beam bracketing structure consists of two support brackets fixedly mounted to the door panel, and a locking means for locking each end of the beam to an associated one of the two support brackets.
