Säkerhetsburar

Säkerhetsburar, commonly translated as safety cages or roll cages, are structures designed to protect occupants of a vehicle from injury during a crash or rollover. These structures are particularly prevalent in motorsports and off-road vehicles, but can also be found in certain performance-oriented street vehicles. The primary function of a säkerhetsbur is to reinforce the vehicle's chassis, preventing it from deforming and crushing the passenger compartment in the event of an impact.

The construction of a säkerhetsbur typically involves a network of strong metal tubes, often made of steel or chromoly, welded together to form a rigid frame. This frame is strategically positioned around the occupants, encompassing the roof, pillars, and sides of the cabin. The design and placement of the tubes are crucial for effective impact absorption and occupant protection. Different types of säkerhetsburar exist, varying in complexity and coverage, from basic roll bars to full multi-point cage systems.

In motorsports, the use of säkerhetsburar is mandated by racing organizations to meet stringent safety standards. They are engineered to withstand significant forces and redirect energy away from the driver. For off-road enthusiasts, a säkerhetsbur provides an essential layer of safety when navigating challenging terrain where rollovers are a higher risk. While primarily a safety device, the addition of a säkerhetsbur can also increase the structural rigidity of a vehicle, potentially improving handling characteristics.
