Title: Streamliner seat and floor
Post by: Mean Gene on November 24, 2009, 12:34:35 PM
Can the secondary flooring of paragraph 3.G also act as the seat of paragraph 3.D.1?  I will be constructing a streamliner and my seating position will be essentially flat on my back.  It would seem logical to combine these two rule requirements, but I wanted to make sure while still in the design phase.

flat on your back is not good.... your ear drum should be at least 6" above your butt...

One of the problems with lay down cars is the seat belt arrangement, You will need to work with the belt mfg. and the SCTA rules committee to assure they agree. Visability is another issue in that position, both forward and the 120 degree requirement. You need to address these issues before the build. Just trying to help. They will probably ask for sketches etc. to work with you.

Another issue you may need to address with a very high degree reclined position is SFI 38.1.
I am not sure but I think most are supposed to work with the belts and are not designed for lay down applications.

Again....I dont know.


Good luck.....and you wont be the only person that might have issues with the new rule.

While the answer is yes, pay attention to what everyone's input here.  You will want that to be secondary walls and flooring, and not a lot of wiggle room if you are not going to have a seat.  I think you will have a "hans type device" issue and look at the belt suggestions for lay down cars.  You will need to have your head and shoulders up a little or you won't be able to feel where the car is going.  Make sure you are wearing a firesuit and helmet when you finalize your seating position and windscreen.  I can recommend you try to get it where you see less than 60 feet in front of the car, it will help when you are trying to hit a turn-out when the crunchies are bad.  We rarely get on one with the lakester... it is a little hard on the nose paint.
When are you planning to be done?  If you get to Denver, I can arrange for you to sit in the lakester to help with ideas.  Or just stop by during the WOS, we will have the lakester there.
Good luck with your project

All excellent pieces of advice.  Thank you for your input.  Based on everyone's input I may have been a bit greedy in my initial idea for seating position.  I'll shoot for Stainless1's 60 ft suggestion while keeping the belts and hans in mind.

Thanks.

Mean Gene, another thing to consider is to buy a bunch of PVC tubung and do a cockpit mock up. You can do it on a bench with casters so you can roll it around while working on it. Something about one foot off the floor for ease. Use PVC  tubing of at least 1 1/2"


Don't glue it as you will find it's pretty stiff and allows  for changes easy. You can use elbows and straight couplings. You will find it saves a lot of headaches and $$$$ up front. Like they mentioned above having all safety gear on for fitting is critical. Good luck on the build and don't be afraid to ask questions and do a photo and build diary.

You didn't say what area you live in but there could be close to some of the other LSR people that can give you some help.
