Air bag deactivation for track use??

Hi, my time attack rules changed this year. I wanted some help on two of the rules for me here in Chile

1) Airbags have to be deactivated.... Is that normal??

2) Four point harness mandatory but roll cage is not. I thought a harness should always go with a roll cage?


Any help would be very much appreciated!!

1) Depends on the organization, but yes, it's fairly normal.

2) Harnesses *should* go with at least a roll bar, IMO. That said, I think it is a somewhat a conservative guideline in cars with really good rollover rating.
 
If I'm not mistaken your car will have the side airbags in the seat. The easiest way to deactivate your air bags is to unplug one of the connectors for the airbag in one of the two front seats and that will deactivate the whole system and the airbag light on the dash should illuminate. If I am mistaken please someone correct me.
 
OP, you are correct--you don't want to run any harness without roll protection. NASA doesn't even allow 4 pt anymore--stock 3pt or 5+. No idea why you would want to make people deactivate airbags.

Unless the rules have changed this season, at least for NASA Northeast, the 4 pt ASM system that Schroth offers was allowed. There is no reason for them not to allow this if they allow a 3 pt system, as the ASM allows the body to rotate in a crash as a 3 pt. does.

In theory, a harness strapped-in driver
may also be distracted, mildly injured, vision obstructed, and unable to work the steering wheel after airbags deploy. I think it's prudent to have the airbags off with roll protection, helmet and harnesses.

Pete, I thought NASA Nat'l outlawed ALL 4 pts last year.

You get in a wreck big enough to set off the bags, you don't need to see or work the steering wheel cause you are done.

Probably, but how do you know?

I'd rather not take the unnecessary hit(s). I don't get what you think the benefit is.
