The original webbing material for my 4-point harnesses is so stiff, it tends to loosen repeatedly when we fly.
Does anyone have suggestions for a replacement harness? (e.g. brand and/or model?)
Thanks.

I replaced my whole harness with one made for the RF4
check out www.wingsandwheels.com/Page27.htm and look at the Schroth seatbelts.
Custom colors and it works nicely

Hi James,
You might think of rewebing your belts.

Hi James, Guys,
I expect you all know this already, but the shoulder harnesses (RF4 and RF5) are supposed to be crossed behind your back before going over your shoulders and down into the buckle.
If you don't cross them over behind you, they will keep falling off your shoulders like a girlie's bra strap. If this happens under side loading during an accident, your upper torso will have no restraint and you might snap your spine, or hit your face on the instrument panel.
Just a thought for folk who didn't know.
Yours, Bob

On the subject of shoulder harnesses I was under the impression that an attach point below your shoulders would, in the case of a accident, compress your spine. If a cross support was added to the canopy with vertical stiffners would this be enough to support the force of a survivable accident? I can see it now, I am in the cockpit post crash my spine is compressed to dwarf type demensions, my girlie bra strap shoulder harness is hanging down and my girls are loose for all the world to see. And that is not a pretty sight for a 51 year old man.

Update -- I talked to the folks at aircraftbelts & they said that unless the restraints were specifically TSO'd, they could not reweb them & have them legal for flight in the U.S. I couldn't give them a specific TSO number, so the only solution seems to be to replace the entire restraint.

Update:
Have sent my seat belts to www.hookerharness.com who can either re-web or replace the harnesses. Their products look the closest to the original restraints and their prices seemed reasonable (not the cheapest, but half of what some of the glider places were quoting).
Will post an update about final resolution.

fwiw, I ended up buying a new set of 4-point "military style" harnesses from Hooker. Similar to what was in the aircraft, high quality, but they do weigh more.

Hi folks,
Further to my comment above about crossing the shoulder harness behind your shoulders, here's the FAA's recommendations, taken from Aircraft Inspection and Repair.
I also read somewhere, that provided the downward angle from your shoulders to the rear attach points is less than ten degrees, it's OK, but I can't find that reference.
The most imoprtant thing is: DON'T CRASH!
Yours, Bob

Any current recommendations for replacement 5-point harnesses? The hardware is fine so I'd rather just reweb. Tnx

We replaced the whole 5-point harness with hardware after the gear up landing with XSK.
We already had a Gardringer 5-point harness installed before that also was starting to loosen the shoulder straps as you flew along and (the worst part) unattached one of the waist belts sometimes in air or when rolling on the ground despite the fact that you yanked in the belts after locking to make sure that they where done up properly.
We replaced the old ones with a new gardringer 5-point belt wich cost us about 500€ and it also comes in a range of different colours so we bought royal blue harnesses to match the blue colour of XSK.
If you buy a gardringer belt i recommend that you file down the wings on the release buckle. In sweden this has been a national TN for years in order to minimize the risk of inadvertely release the buckle during eg. aerobatics.
