A reinforcement tube having high strength, toughness and resilience for use as an absorption element in a motor vehicle door, the reinforcement tube having a cross-section in which a first dimension of the cross-section is greater than a second dimension of the cross-section, the second dimension being perpendicular to the first dimension.

Motor vehicle door reinforcement tube and a process for manufacturing the reinforcement tube

A light-weight, corrosion-resistant, readily installed bridge deck is formed of modular deck panels spliced to each other on site Each of the deck panels is shop-fabricated by longitudinally welding flanges of adjacently placed multi-void extruded aluminum alloy structural elements Transfer splices of longitudinally adjacent elongate elements are made by providing shear elements connecting individual elongate structural elements of each deck panel end-to-end prior to longitudinal welding of adjacent elongate elements, with the end joints between the elongate elements being arrayed in a staggered manner A safety rail system is mounted to run alongside and above outer edges of the finished bridge deck mounted to a system of support girders

Curb and safety rail system for a bridge deck

An anchor assembly ( 3 ) for securing at least one safety device indirectly to a structure is disclosed. The anchor assembly includes at least two spacers ( 10,20 ), including a first spacer and a second spacer; at least one bridging member ( 50 ) spanning between the spacers; and engagement means ( 30,40 ) for securing the safety device to the anchor assembly. Each spacer includes securing means for securing the spacer directly to the structure; a head for fastening the spacer to the bridging member and/or to the engagement means; and a shaft extending between the securing means and the head. The shaft of at least the first spacer is adapted to deform progressively so as to at least partially absorb the kinetic energy applied by a load of a falling object attached to the safety device.

Anchor assembly for safety device

The present invention relates primarily to highway safety devices, secondarily to on-board vehicle mounted safety devices and more particularly to enhancing the performance of such devices when occupants of vehicles are subjected to severe deceleration forces.

Gating Impact Attenuator

A one piece beam means used a post to support a longitudinal impact-resistant member, such as a guardrail along a highway. The one piece, stamped construction simplifies installation because fewer steps and parts are involved.

Ground support beam for longitudinal barrier

A post for a guard rail used on a highway. Said post is made of an aluminum cast alloy, and is formed in an I-shape in a horizontal cross section, having a central web and front and rear flanges, and being wider at its lower portion. A mechanical neutral plane of the post along the widthwise direction thereof is formed in an S-shape, so as to provide sufficient plasticity and supporting ability to absorb an impact load of a vehicle and to protect a driver from injury.
