The shoulder harness issue is very simple, the big auto manufactureshave them so they must be good. This being the results of thousands ofcrash test. How about building a small support structure above theturtle deck, attaching the seat belt and transcending down at an angleabove the shoulder its when the belt loops up and over the shoulderfrom behind that the body moves forward and is compressed!Russell----- Original Message -----________________________________________________________________________________

Shoulder Harnesses

Subject: Shoulder Harnesses One of the subjects that I'm very interested in right now isshoulder harnesses in Piets. I saw two different examples at Benton and I'm wondering whateveryone else has done? This is a subject that I hadn't worried about until now and I wentback over all my Piet pictures and couldn't find a single picture ofsomeone's installation. One of the installations was through a raised turtle deck(Joe Becks)and the other was going to be through a fiberglass head rest(ChuckGantzer). Unfortunately my digital camera didn't take good pictures ofeither one of these.(bad lighting) I hope my 35mm did. I haven't finished glueing my turtle deck down yet and I'mconsidering raising it so I can run my straps through it and back to mysturn post. I'm also concerned with attaching the shoulder harness anywhereexcept the sturn post. Anybody want to comment? Thanks, Greg Yotz________________________________________________________________________________

One thought that I can add to this, that I learned from the pros. Theshoulder straps should go up your chest, over the shoulder, and STRAIGHTIN, as much as possible, to the bulkhead. If not , in the event ofaccident, your body goes forward, and the spine compresses.Not a pretty thought.waltps My Fisher's shoulder harness attached to tailwheel fitting at thesternpost. -----Original Message-----

Good thinking
...... You may die of internal injuries... rupturedbladder & spleen, etc...., but at least your back won't be broken!!!It is foolish in the extreme to dispense with sholder harnesses forfear of a broken back. Seat belt alone will cause grevious internalinjuries in case of a violent stoppage.... the sholder harness willprevent this. The correct approach is to design a sholder harnessinstallation which will not result in compression of the spine. Acompression strut(s) (vertical) could prevent this problem and allowyour strap to fasten low. This reminds me of the people who refuse towear a seat belt because they know of someone who burned to deathtrapped by their seat belt...... without consideration for all thosewho were thrown from the vehicle and killed due to not being strappedin. I use a full 4 point racing harness available from your localspeed shop for about $ 75.00 in either a double seperate sholderharness system, or a system where both sholder harnesses are sewntogether with a single strap passing to the rear. I use the lattersystem. This isn't in a Piet however.H.W.-----Original Message-----

You may want to sit in the Piet cockpit, and look at how close your faceis to the panel. The cracked back may be better than the fracturedskull. It seems to me that when i joined the EAA way back, I had tosign a form stating that I would install shoulder restraints in anyamateur built plane that I did. Must be a reason!It might look funny, but has anyone put a post up just aft of the seatback?I still don't know what to do with the shoulder strap attach point, butwhen I sit there and lean forward, I know its going to be worse than aface plant in skiing!________________________________________________________________________________

Walter: My comment was not directed at you in any way.... John Langstoncommented: " We don't plan on installing them in our plane." Aftermentioning the problem of spinal compression. The implication beingthat out of concern about spinal compression it was decided not to usea shoulder harness. Perhaps John feels that sudden death by violent head injury orinternal injuries is preferable to life as a quadriplegic. If so Ican relate to that concern..... I almost left off my crotch strap frommy 5 point harness out of similar concerns. However in the case of the shoulder harness proper design willprevent either eventuality....... (head injury or spinal injury). In the case of my crotch strap, at age 44, I'm perhaps past mysexual prime, and if I were to suffer damage as a result of thatstrap, I could look on the bright side of things and see that it wouldsimply leave me with more time for other activities such as flying.-----Original Message-----
