摘要：An energy absorbing vehicle barrier includes a frame defining a compartment. In one embodiment, the frame includes a nose. An energy absorbing cartridge is disposed within the compartment. A retaining device is coupled to the frame, with the retaining device disposed above and extending over at least a portion of an upper surface of the cartridge. The retaining device may contact and engage the upper surface of the cartridge when the barrier is impacted by a vehicle. In this way, the retaining device substantially prevents movement of the cartridge in at least a vertical direction during the impact. Methods of using and assembling the barrier are also provided.
