Lumbar Support / Firestar

Hey Guys,
On short trips , it doesn't bother me ...But on my longest
Cross Country ( 400 Miles ) ....Well, longest so far...

I noticed that I needed a little "lower back support"..I used a towel once,
but it didn't really work very good.....

While I was at work....I was sitting in the break room one day....
We have the office "OLD" swivel/rolling chairs.....

I noticed this "Bulb" hanging from the chairs....
They have a bladder inside , and the bulb will inflate or de-flate it....

Man, do they got those things GLUED in there.... I put a couple of holes in it because I was trying to get it out without pulling off the back of the chair.....Which I had to do anyway.... Holes are fixed now...

Well, I'm gonna have "Lumbar Support" in my Firestar.....Cool

" Little Details"

This was cut out and sanded smooth inside and out.

Even though I sanded the edges, I also put some duct tape on to give it a smooth surface...

Last Picture

The bulb has a piece of velcro in the form of a "Tag" it can be stuck to some Velcro that I have on the back of the seat...
I'll still be able to grab it if I need to...

I got in the seat and pumped up the pressure til I liked it....it feels like it's gonna work like it's supose to...
After I got out , I looked at how much it bulged out the seat...not too bad...

You never cease to amaze me with some of the innovative solutions you come up with.  This is just another example of a great idea!  Kudos!

I just wish I could use some of your ideas on my Cessna 152 without needing a form 337 and FAA engineering approval...

Guess I need to get back to working on my build...
