All -

For the third year in a row I've somehow managed to injure my back
early in the season (base of the spine/sciatic nerve). I'm beginning
to suspect its not my day-job or rigging my ship (I have a one-man
rigger); but rather my flying and seating position in the cockpit
(DG-300). Short early-season flights don't seem to cause a problem;
but a couple of long flights in a row (or a long drive in the car + a
long flight the same day) may be what's touching it off... Its
getting VERY frustrating to be bed-ridden for a couple of days (at age
33)!

So while I get going with physical therapy (again) and meds (again),
I'm thinking about ways to change my cockpit and take pressure off the
base of my spine. I've already added some seat-foam; the only other
thing I can think of is to try not to have my spine bent in such a "U"
shape.

Anyone out there have suggestions on creating a lumbar support pad?
As I understand it, the pad should sit between the parachute and my
back (not between the 'chute and the seatback). Tips or ideas would
be greatly appreciated!

Noel,

I know a fellow that use to ride bicycles a lot and now has to sit on a cushion. The type of foam you are sitting on may not be correct for you. I have only minor back issues but I'm short and instead of using some kind of seat foam that may compress too much I read up on the Confor Foam and opted for 3 pieces of 1" each of the hard, medium and soft. I glued them together and trimmed to fit in the seat pan nicely. I then trimmed a raw cut piece of lambs wool to cover the foam and the entire pan seating area. It is great. No part of of my body hurts nor goes to sleep nor do I have any aches or stiffness after getting out of the glider. I had a job where I sat in an office chair for 25 yrs. The last 5 I had to use a mesh bottom and back ergonomic. And now I can not sit more than a few minutes in a regular chair. So, the type of foam you use may not be right for you.

Too bad - the foam would've been much cheaper!

This is what I did. I bought a sheep skin pad for my National 425 that goes between my back and the chute. I using adhesive velcro tape, I velcroed' a small lumbar support cushion to the back of the chute container, and velcroed' an inflatable lumbar support bladder to the back of the sheepskin. The lumbar support bladder has a hose that runs up the shoulder strap and ends with a squeeze bulb similar to a blood pressure cuff. Usually the lumbar support cushion is enough, on long flights, a little inflation on the bladder makes life good again.

I bought an inflatable lumbar support cushion from an ad in Soaring
magazine almost 30 years ago. It still performs and I still love it.

I would be really careful with inflatable support. In case of an accident you might end up with a big problem. The inflatable will not support the spine. Crush foam is a much better solution.

I use a one inch thick piece of Confor (Memory foam) in green, extra firm. Cut top and bottom edge at 45* and slip it between the sheepskin liner and pack. Very comfortable.

And it lasts for years...

I bought a pump-up blood pressure cuff.
You can take the bladder out but I found the fabric cover to provide some stability to the positioning of the bladder. The beauty is that you can pump it up or bleed it down when you want/need.

There are probably two different issues: cockpit comfort and crash protection (for the spine). Inflatable cushions no doubt provide comfort, but my guess is that they provide nothing towards crash protection. EAF cushions probably provide both, but can be awkward to get right. A motorbike back-protector should make an excellent shell to slip between my back and my chute, and provide a mount to glue some EAF where the cockpit contour makes a void under my back.

Motorcycle back protectors provide little to no protection in the vertical axis when sitting. And may move crash injuries further up the spine.
