Another question for pilots
I am building a couple of track cars and I am trying to find a source for some hardware for mounting the shoulder harnesses. What I am looking for is usually called a footman's loop and was used by Porsche on some of their race cars. Sometimes it was a formed wire loop, sometimes it was a bent piece of sheetmetal. It looks like this, more or less:
 I figure that a version of this has been used in aircraft over the years. Maybe military, maybe in helicopters, maybe in something old. I'd like to find a source for these, as the ones you can get from commercial sources or army surplus are basically cast pot metal and not suitable for my application. Any and all help appreciated, JR |

I haven't seen anything like that in airplanes I've flown but try http://www.aircraftspruce.com/
They have just about everything airplane related.

Hmmm ..... I do not recall ever seeing any aircraft harnesses secured by anything like that. That looks more like something you would see in a car to fasten baggage straps with. I can't recall the recommended rating, but most aircraft belts loop thru a plate which is then attached by a bolt or by cable ends to a substantial load bearing point of the airframe. I think they are designed with quite a high g-load rating (don't recall the load rating and it probably varies with class of aircraft) to resist the 100+ lbs being slammed forward in the event of sudden stoppage.

A couple pics of my ratcheting double lap belt in an aerobatic plane I am building. I just threw it in there with some incorrect temporary bolts. I actually am using two seperate welded 4130 attach points as a safety measure should the main ratcheting belt attach point or fitting fail.
The other pic shows my Piper's Hooker shoulder harness attach point on the ceiling.

Those are a marine item for holding battery cases down to the floor in the engine area, stainless I think. I have seen them in old cubs in the baggage area also.
