Energy Absorption Systems Inc. | Date: 2013-05-30

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.

A delineator system includes an anchor having an end portion and a post extending along a longitudinal direction and having an end portion overlapping with the end portion of the anchor. The overlapping end portions are coupled together with an engagement member. A protective collar is moveable relative to the post and the anchor along the longitudinal direction from a non-installed position to an installed position. The protective collar is disposed over and covers the overlapping end portions and the engagement member when in the installed position. Methods of manufacturing and installing a post, and other delineator systems and delineator posts are also provided.

A guardrail system includes a plurality of posts spaced apart along a longitudinal direction and a plurality of rail sections extending between and coupled to the spaced apart posts. Each of the rail sections includes an uppermost surface. A cable extends along the longitudinal direction and is coupled to the rail sections and/or posts. The cable is vertically spaced above the uppermost surface of the rail sections. A guardrail retrofit kit includes a front anchor bracket, a rear anchor bracket, an intermediate bracket and a cable having end portions adapted to be coupled to the front and rear anchor brackets. The intermediate bracket is configured to releasably capture the cable. Methods of retrofitting a guardrail system and arresting a vehicle impacting a guardrail system are also provided.

A frangible post captures and holds a cable anchor to a guardrail. The post breaks when struck by a vehicle, releasing the cable. The frangible post may include hinge members, which bias the post so that weakened sections are put in tension when the post is struck, thereby ensuring that the post breaks cleanly and the cable is released when the post is struck. A method of releasing a cable anchor includes impacting the post, biasing the weakened sections so that they are in tension, breaking the post, and releasing the cable anchor. The post may be configured with a notch to engage the cable anchor, which is then released from the notch as the post is broken.

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.

A delineator system includes an anchor having an end portion and a post extending along a longitudinal direction and having an end portion overlapping with the end portion of the anchor. The overlapping end portions are coupled together with an engagement member. A protective collar is moveable relative to the post and the anchor along the longitudinal direction from a non-installed position to an installed position. The protective collar is disposed over and covers the overlapping end portions and the engagement member when in the installed position. Methods of manufacturing and installing a post, and other delineator systems and delineator posts are also provided.

A crash attenuator includes a frame having a first frame member and a second frame member rigidly connected with a hinge assembly in a pre-impact configuration. The first and second frames are hingedly connected with the hinge assembly in an impact configuration, wherein the hinge assembly comprises a living hinge when the hinge assembly is in the impact configuration. A method of using the crash attenuator is also provided.
