An impact bar is a special mechanical device that distributes the load of an impact over a wide surface area. The bar is made with a special rectangular design that forces any impacted weight to be distributed of the entire surface area of the bar. These types of bar designs are often used in safety equipment for automobile doors, bumpers, and roll cages. They are also used as weight support for conveyor belts.
Many cars and trucks include impact bars throughout the passenger compartment. These safety devices enclose the occupants with bars in the doors, bumpers, and roof. The bars make the car safer for collisions and rollover accidents.
An automobile bumper is typically based on an impact bar design. Bumpers reduce damage to the car and occupants by limiting the explosive effects of a collision. The bar has in internal rectangle cut-out area that is designed to spread the load of impact across the entire beam. This makes it easier to support heavy loads during crashes.
Impact bars are available in many types of material. The most frequently used are rubber, metal, or hardened urethane. The type of material determines the weight and distributed load the barcan support. An impact bar made from hardened urethane is considered one of the most durable because it is more resistant to wear.
