Abstract

A crash cushion including a side portion extending in a longitudinal direction and having an outer surface defined at least in part by a plurality of convex cambered portions. At least one deflector skin has an inner surface, an outer surface, a leading edge and a trailing edge. The deflector skin is mounted to the outer surface of the side portion in an overlying relationship with at least one of the convex cambered portions.
