Tried and tested Roll Cages from the pros!!!!

More food for though on the Roll Cage and Seat Belts subject:

Down here in order to race in the African 4x4 desert rallies like the Paris-Dakar rally http://www.dakar.com and the Rally of Egypt http://www.RallyOfEgypt.com, we have to adhere to the FIA (International Auto Federation http://www.fia.com)regulations. The FIA has done extensive research on roll cages, seats and seat belts structure, design and mounting methods. If done properly, the FIA cage/seat/seat belt setup offers excellent crash protection. Iíve seen several high-speed crashes where the drivers, unlike their vehicles, sustained little injuries.

Read the regulations carefully since it include a lot of information about how and where to join/weld the tubes, how to mount the roll cage itself to the floor/chasis. It also includes a lot of useful information that will help you build a cage that will save your life.

The regulations also include info on how to use removable sections in the roll cage, which is very interesting since not all of us have dedicated off-road rigs.

Article 283- Safety Equipment for Cross Country Cars
http://www.fia.com/regle/reg_tec/283-a.htm
Scroll down to the Seat belts section. The roll cage is in the Rollover Structure section.

283-3 to 283-6 http://www.fia.com/regle/reg_tec/dess-a/board22.htm

If you visit the FIA site yourself go directly to the site map. The site's menu structure is confusing and incomplete.

Hope this helps [img]/wwwthreads_images/icons/cool.gif[/img]

Re: Tried and tested Roll Cges from the pros!!!!

Thanks Ahmed

I completely forgot about the FIA (In english, the International Automobile Federation) Pro Rally formula. Another source of information would be the SCCA (Sports Car Club of America) Pro Rally rules.

For everyones information, these guys are mainly go fast drivers on the ****tiest tracks imaginable. If they crash, it's usually at high speed so they build for greatest structural integrity with the least weight.

I'll see if I can find the SCCA rules.
