An energy absorbing panel assembly for the interior of a motor vehicle is disclosed. The energy absorbing panel assembly, typically the knee bolster panel adjacent the steering wheel, includes an energy absorbing structure integrally molded to the panel. The energy absorbing structure includes three outer side walls and a top wall. The outer side walls extend from the same side of the top wall to the panel. Extending from the top wall to the panel is at least one top wall supporting rib. The rib is positioned between the outer side walls. At least one of the outer walls is at an obtuse angle relative to the plane of the top wall. All three of the outer walls may be at an obtuse angle relative to the plane of the top wall. Lateral supports may be provided between the outer side walls and the panel.
