发明名称 Apparatus with collapsible modules for absorbing energy from the impact of a vehicle
摘要 Apparatus for absorbing energy when impacted by a vehicle includes relatively movable vertical, spaced supports supporting modules extending between the supports. At least one of the modules has elongated openings formed therein which define deformable module side wall strips located between the module ends. These module side wall strips bend in response to application of opposed forces to the module ends.
