Abstract
Energy absorbing bolsters for vehicle doors are usually formed of non-recyclable foam plastic and/or metal. A relatively simple bolster, which can be formed of recyclable plastic, includes a hollow body with a hole therein for equalizing interior and exterior pressure, and permitting limited flexing of the body, and reinforcing ribs on the outer and side walls of the body, so that the latter can be relatively thin walled.
