2.8 Brief about Invention A vehicle crash cushion for decelerating a vehicle includes front and rear anchors spaced along a longitudinal direction and at least one deformable attenuator member extending in the longitudinal direction and having a first end coupled to the front anchor and a second end coupled to the rear anchor. A support member is positioned adjacent the attenuator member and is moveable in the longitudinal direction relative thereto between at least an initial position and an impact position toward the rear anchor and away from the front anchor. At least one deforming member is mounted on the support member and is engaged with at least a portion of the attenuator member.
