Who invented the roll cage?

Answer 1

The first roll cage ever built was in 1964 by a man Called John Aley

(founder of Safety Devices roll cages) after he had a near fatal crash and wanted to improve the rigidity of his car. The first roll cage was nothing more than a few strengthening bars strategically placed to reduce the deformation of the car in case of an impact. After the FIA realised the benefits of roll cages they became mandatory in all competition cars. After further research and development was put into roll cages it was found that by placing the legs of the roll cagein certain it places it benefited the cars handling.Over the years huge research was put into the design of roll cages and the materials used after discovering the handling and suspension benefits it provided to competition vehicles. This development through the years has made roll cages very effective and had resulted in limiting the amount of deaths and made a huge reduction in the amount of serious injury's caused by crashes that may happen during a motorsport

event.

The research has also led to the use of better materials in rollcages.

The first roll cages simply used steel bars but modern day roll cages use aircraft grade steel for extreme strength but minimizing the weight of the cage.

Answer 2

A roll cage was first made by Jeff Posey but everyone took his idea. He started making them about four to six years ago and they go on vehicles called rhinos.
