Helmet Support

[maguromic]

I know there have been a few threads recently on this subject, but I want everyone to post pictures of swing away helmet supports they might have.

I am designing the seat on the Firebird and would like to see what others have done for a swing away head support.  There are a few on the Firebird build thread that Tman posted for starters, but I don't know how to move them here but maybe Trent can re post them on this thread.  Tony

Tony - Perfect timing - I just finished the seat install today -



SFI foam all around the inside.



Stroud door net in place - drop net -



Spring loaded dead bolt on hinge - pull ring -



Push out.  The entire contraption is bolted to the back of the seat, and the top 1/3 of the seat is drawn tight against the head bar with grade 8 bolts and a muffler clamp.  Down and dirty - yes - but you can stand on those laterals, and they do not move.



I do wish that this rule were not so absolute, especially on cars looking at slower records, but if it can be done in a 5 lb car with a 10 lb driver, it can be done.

Tony, I got my inspiration (OK, I stole the idea..... ) from Don McMeekin's 240 SX.
His setup is simple yet effective and uses a pip pin to lock it in place. This did passed inspection at Bonneville in 2011 and 2012.






Mine is the same type of setup but is part of the seat. I will also use a pip pin to lock it in place. It doesn't look like it moves much but is enough to give me good ingress/egress.



















Hopes this helps.

Chris, you are really exposed out there at the back of the cage, you sure that will pass tech?

Here's a better shot from early on.



There are two bars running to a bar between the rear wheel wells that's stitched to the frame work.

Chris, I "think" I see what Sid is concerned about.
In these pictures, it seems there should be more bars surrounding your helmet.
Your head is behind the main hoop so there is nothing protecting you at the sides of your head except the lateral support.
Is this what you are talking about Sid?





I know you have raced with the ECTA and probably passed their inspection OK but they are not the SCTA.
If it were me, I would shoot some pics off to the SCTA and see what they say.

Sorry for raining on your parade,

Yep, that's what I was talking about. The scale is a little different with you head parked in there but I still think it's a problem.
I'm not about to tell anybody how to build their car but if you plan to run SCTA you might want to get their blessing to avoid disappointment.

On the upside Chris, because the roof is detachable it looks like an easy fix if SCTA requires the change.

Our LSR cars are never really finished!

I appreciate the input - thanks!

Thanks for the pictures, it really helps to visualize what needs to be done.  I am leaning towards a spring loaded support with a quick release that is activated by a cable similar to a fire bottle cable.  There will be one for the left and one for the right in case you have to go out the passenger door.  Tony

Wow your car has a passenger door that is accessible? cool.

Not really, its just a pacifier.  Bit if there was an emergency I think you should be able to squeeze out, maybe  I need to take up yoga.  Tony

If your avatar's are anything to go by, you might be getting all the "yoga" you need Mate!
