Pietenpol-List: Seat and shoulder belts

Post by matronics »

Original Posted By: jimsury(at)fbtc.net (Jim Sury)
While sitting in the fuselage the other day, the thought crossed my mindthat my face was very close to the instrument panel, and that I wouldprobably want a very firm shoulder harness to protect the brain bucket ifexperiencing extreme deceleration, ie a big boo boo.Only question that comes to mind, and is absent on the plans is where toattach the seat belt in the rear cockpit, and where to attach the shoulderharness in both cockpits. The front pit I think could be attached to thelanding gear fitting. However, more hardware (weight) me be needed back ofthe rear seat. What and where are you guys attaching same to? Are you running wirecable(s) from an aft location? ________________________________________________________________________________

The seat belt can be attached to cable fromthe back bays but how do you do the shoulder harness since the shoulders areabove the rear turtle deck. The attachment point for shoulder harnessesshould be above the shoulders. If they are below the shoulders I understandthat on impact the force drives you down crushing your spine. And thatwouldn't be too healthy. I really don't know how to attach the shoulderharness. We need help with this one.Jim________________________________________________________________________________

I bolted through the gusset and the vertical uprights.To thishardpoint on each side I ran a piece of cable that loops forward towhich the shoulderharness anchors.Stevee________________________________________________________________________________

I think I found the bolt you describe in the picture taken back into the fuselage.I don't understand the route taken by the cable that loops forward. Could you describe it to the point that it is painfully obvious?Or, perhaps you could add a photo on your page showing it??By the way, a great photo of your ship by the mountains!Dick________________________________________________________________________________

Thanks very much for the info and comments. I found the home page of Steveeand the picture was worth a thousand words! and much head scratching. Thecomments about having the attach points above the shoulders will not workout in a piet. The lesser damage is likely a sore back vs a mushed in face.

The lesser damage is likely a sore back vs a mushed in face.> One way around it if the turtle deck is already built is to add a headrestwith the harness coming out the top. Otherwise I would raise the turtle deck tothe same height as the coaming foward. I've seen Piets like that and I think they look better anyway.john________________________________________________________________________________
