Seat belt rides up, falls off shoulder etc

On a previous post this is what roger said:

 

Here's the real problem.

There are basically 3 grades of webbing. The thinnest and most pliable is what FD uses. Then there is a middle grade (a little thicker and a little less pliable and a the top grade which is really thick and not very pliable at all. I used to use these webbings when I owned my last business. The middle grade is what we used and it is what FD should use. The top thicker grade is too stiff and thick. The non slip buckles don't work for .02 cents with the thin webbing. They need to use the middle grade so the belt has enough thickness and stiffness to stay put. I just use two velcro straps on my harness at my upper chest level and they work just fine. I hope FD reads this and changes its web material to the next grade higher. I suppose you could yank the harness and have a shop redo them with the next grade webbing. It may not be legal, but you could file an LOA or......

 

 

Then it seemed the post started talking about something else and it was never finished.

 

Has anyone figured out anyhitng that makes the seatbelts stay tight?

Safety Officer, if we make this modification that you recommend, do we need to make a log book entry?

I fixed mine by only wearing it during takeoffs and landings.

Are there any stats on how the belts held up when a CT flips over ?

My belts keep on getting loose to the point that if I crash I would need to add a checklist item to pull them tight before hitting whatever and wonder if they would hold.

Hey safety officer why would FD not give a LOA for something that improves safety and does not affect the cg ?

Does the LS have the same problem?

In or near Hopkinsville Ky where would one find this webbing shop?

sewing shop has seatbelt material?

Even though LSA are not subject to some of the FAA strictures, it doesn't hurt to give them a look. There is a TSO on seat belts that calls for testing.

Here is some FAA propaganda on use of seat belts.

No matter where the seat belt material comes from, it would behoove us to be sure that it meets the standards that we will be judged by if there is an accident or we are inspected.

Roger, how would a person know what grade webbing that aircraft spruce is selling? They do not mention the grade? Im also quite certain they would not know if i asked them....

I'm also frustrated with the seat belts constantly becoming loose. I want to try removing the chrome slides, but at first attempt, they did not pop off easily. For any who have done this, what is the sequence that works best?

 

Also, has anyone changed out the web material, and if so, does this really help? I'm surprised that Flight Design hasn't addressed this issue. Loose belts are a hazard if actually needed.
