ABSTRACT:
A plastic bumper for use in an automobile includes a front wall member generally having a U-shape cross-section, and a rear wall member having a mid portion intermittently indented to form a plurality of pyramid frustum shaped recesses. An outer end face of each pyramid frustum recess is adhered to an inside face of said front wall member. Thus, the bumper is reinforced with respect to vertical and horizontal impacts.
