An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy. They may also be designed to redirect the vehicle away from the hazard or away from roadway machinery and workers. Impact attenuators are usually placed in front of fixed structures near highways, such as gore points, crash barrier introductions, or overpass supports. Temporary versions may be used for road construction projects.
Impact attenuator
A crash cushion includes a first barrier frame and a second barrier frame, each having laterally spaced first and second sides defining first and second planes that slope inwardly from a top to a bottom of each side of the first and second barrier frames. The first barrier frame is movable relative to the second barrier frame in response to a head-on impact. First and second side panels are attached to the first and second sides of the first and second barrier frames, respectively, wherein the first and second side panels are movable relative to the second barrier frame in response to the head-on impact. In one embodiment, the side panels can have a variable cross-sectional shape along their length. Further, each frame can include a plurality of longitudinally spaced guides for engaging a rail.

Protective helmet
A safety helmet, for example, usable in sports such as football, is shown and described. The safety helmet includes an outer shell and an inner shell. The latter encircles a head of a wearer of the safety helmet. The outer shell is coupled in spaced apart relation to the inner shell by impact attenuators that include in one variation elastically deformable pins. The pins protrude through the inner shell to the inner head seating structure, and outside the inner shell to the outer shell. In another version of the impact attenuators, the pins are bound to a lattice construction providing openings further accommodating deformation responsive to impact forces. Inner and outer shells may have holes to accept ends of the pins. The number of holes may exceed those actually occupied by ends of pins, thereby providing adjustability in number and location of either version of impact attenuator.
