Abstract
Abstract A bumper assembly including an elongated metal bumper, at least one self-supporting impact resistant plastic upright bumper guard and at least two longitudinal bumper guards secured to the bumper on opposed sides of the upright bumper guard. The upright bumper guard includes a U-shaped portion conforming to the bumper and opposed integral tabs which overlie the bumper and include integral connectors. The longitudinal bumper guards are channel-shaped in transverse cross-section and enclose the upright bumper guard tabs. The longitudinal bumper guards include connectors integral with the side walls of the channel. The bumper includes a plurality of apertures which lockingly receive the connectors. The upright bumper guard is assembled first on the bumper and the longitudinal bumper guards are disposed over the upright bumper guard tabs and secured in place by forcing the connectors in the bumper apertures.
