Re: [BrianSGermain] Butt strap to prevent falling out of a harness [In reply to] Can't Post

Please do not be offended if my comments do not apply to you. I just want to be sure that new jumpers do not get overly paranoid that they are going to fall out of their rigs.

In reply to:

No offense taken of course, and while i understand your point and agree that being overly paranoid about a seldom seen situation is counterproductive, it's no more-so than complacency.

Falling out of a parachute harness is extremely unlikely, however it IS possible, obviously several measures can be taken to lower the possibility even more.

Things don't always go to plan and equipment isn't always used as it's designed to be...if a bungee relieves the stress of concern and gives even a small degree of increased safety, that's a win/win ~ I'm all for it.

...that's all I'm saying.

We are both right. I love it when that happens. :-)

I like your thinking! Feel free to post your leg strap/butt strap idea here http://www.dropzone.com/..._reply;so=ASC;mh=25; There are some interesting legitimate ideas I saw there.

Any sort of idea's in one location I think is great, also allows the manufacturers to see potential improvements and get ideas from the consumers and potentially implement it within their rigs.

Actually right around the time I mentioned my leg straps loosening up while in the plane or walking to the plane with my rig a manufacturer offered a non-slip option right around the time I wrote it(already developed but with another manufacturer)! I thought that was amazing having that option!

I've known my wife for over 30 years, and I'm still waiting to hear her say that.

Let's not discourage people from making their gear safer by rationalizing likelihood.

At the same time, let's not make changes that might pose additional problems without thinking about it and evaluating the risks on both sides.

If you can't tie knots, tie lots.
Hah!
Hah!
Seriously, make the largest and ugliest knot you can think of and it will never pull through the tape loop on your leg pads.
I have made a few butt bungees from old Safety-Stows. I just cut them at the end of the doubled section and tie a knot with the doubled section, then tie a larger and uglier knot in the other end.

Agreed!
This problem only appeared after two changes in skydiving fashions.
First, hip rings were introduced (1991). Most of the complaints came form SECOND owners of ringed harnesses. Several of these second owners were significantly smaller than the first owners.

Secondly, sit-flying fell into fashion a few years later (1994). Now that skydivers were exposing their harnesses to winds - from unusual directions never imagined by harness designers - they started operating "outside the envelope."

Every new skydiving discipline creates new challenges for parachute designers.

In reply to:
If people feel safer with a butt strap, they should attach a butt strap. My point is that it doesn't actually happen all that often. We are making a big deal out of something, but on the whole, it is a non-issue for most people. If your body type, combined with your particular harness, combined with your flying style makes you more vulnerable that the average skydiver, address the issue. The point I was making is that the exception should not be made to appear to be the rule. That is how we lost our right to carry water bottles on commercial airliners.

Please do not be offended if my comments do not apply to you. I just want to be sure that new jumpers do not get overly paranoid that they are going to fall out of their rigs.

Fly Safe,
Brian

To the OP & Brian,

I am aware that the fall out issue on individual sport rigs is small.
The hazard probability of occurrence strongly depends on the jumper-gear match.
To ignore that the hazard exists is to bury your head in the sand.
The butt strap that I show in my article can be made by any rigger.
It's not complicated and only needs one or two measurements.
Steering the canopy is facilitated by the butt strap.

Interesting, you have really given me something to marinate on here. I have wondered, from time to time, why parachute harnesses did not have a slide out prevention system and climbing harnesses do.

I just got my new wings this weekend and it came with a little bungee. I had to put it on myself but it came from wings. "Handsome" Dave was jumping and I asked him what he thought about it and I got the usual "that should work, haaaahaaahaaa!".
