Right Side Safety Net

[marshall_mosty]

Guys,
Looks like a right side net will be required by July of next year, unless your seat has adequate side protection.

Sorry for the link... I don't know how to turn .PDF files into .JPG.



Maybe AJ can get a group purchase together???

who's rules are those?

Interesting stuff.

What is listed as a "preliminary" version of the 2007 CCR can be found here:

Several little changes that people should keep in mind. Remember that SA95 helmets will not be good this year. Time to upgrade if you have an older helmet...

Head and neck restraints still listed as a posible requirement mid year...

How do you hook those things up? I think Chris Lyons has one in his AI car last time I saw it.

Mike this pdf sort of show how they are mounted.

We're eventually going to have so much junk in our cars that there's no room for the driver. Then we will be guaranteed to never be exposed to even the most remote possibility of being injured.

We were just discussing something similar the other day - in particular, these head restraint nets - check out the pics in that Simpson PDF - all these head and neck restraints are severly inhibiting visibilty, which introduces additional risk in itself? They would obviously be a very good thing in a stock car on an oval where you are likely to impact a solid wall at high speed - but in a CMC or SM car at the sppeds and tracks we race at, I think the reduction in visibility, is likely to do more harm than the net could do good, especially if it is yet another think to release or get tangled in in the case of emergency exit?

I have said something similar to this before, but I'll repeat it here - I think systems such as this are all very valid safety items - but not necessarily for every type or class of racing - so there should be general guidelines in the CCRs with specific safety requirements in the class rules.

I'm still confused/concerned about how to mount the forward portion of this little triangle deal. In a CMC car we have stock dashes, no forward portion of the cage in my dash. How could a simple screw or bolt secure this enough to help me in the event of an impact??

remember guys, a safety net is not the only option in this new rule.

The things are clearly designed for oval track racing, IMO. But, the SCCA mandated them, so NASA must do the same or face the wrath of greedy lawyers and litigious gold diggers.

I've brought up the concept of system safety before - the analysis of a complete system including the car, driver, track, other cars on the track, and the types of incidents that occur as well as how often they occur, and just don't feel that is being taken into account here. One small example: With this thing in my car, I'll have a tough time reaching my kill switch if I need to get to it now. I know I can move the thing, but that will cost me time and money because I was very careful in selecting the location that I mounted it and worked hard to ensure that it was safe.

I read a pretty solid write up the other day on a study that addressed how the perception of an increase in safety actually increases overall risk taking in a manner disproportionate to the reduction that a given safety device actually provides and that devices that present a marginal increase in the safety of one component of a system, therefore increasing the level of risk taking behavior that one will see as acceptable and increasing the overall rate of incidents are not uncommon. The study looked at 17 or 18 countries over 20+ years that had mandated seat belt use and, while the injury per accident rate went down after their use was mandated, the number of accidents per vehicle went up, and the overall injury rate often increased. That's not to say that seat belts are a bad thing, which I'm not arguing, just that our cars are a part of a very complex system and changing one thing in it can have unexpected consequences in another area.
