Abstract
A crash cushion includes a plurality of resilient, self-restoring tubes each having a center axis and an interior surface. At least some of the tubes are positioned such that respective ones of the center axes are spaced apart in a longitudinal direction. The center axis of at least one tube is substantially perpendicular to a longitudinal axis extending in the longitudinal direction, with the tube defining a diametral plane intersecting and oriented substantially perpendicular to the longitudinal axis. The center axis of the tube lies in the diametral plane. One or more segments are positioned in the tube, with the segments, or portions thereof, disposed on opposite sides of the interior surface of the tube. Each of the segments or portions is symmetrically secured to the tube relative to the diametral plane, with the tube being substantially open between the opposing segments. Various methods of using and assembling the crash cushion are also provided.
