I considered the same options as you, but decided I didn't want to deal with ripping out stitching, or the bulkiness of 3-bar slides and loose webbing ends. And legality aside, most shops are unwilling to sew seatbelt webbing due to liability concerns. If you cruise eBay, there are some nice, approved AmSafe belts that are a close match for BAS, and have very compact, airline-style quick clips which are small enough to fit through the triangular Atlee belt positioners. Here's an example. Note that the male side is a bit shorter than ideal, but if you place it to the outside, or if you only use it for kids, it's fine.

I bought these ones from Aircraft Spruce: http://www.aircraftspruce.com/catalog/a ... belt2b.php They are similar to the ones Denalipilot posted having the small clips that easily pass through the retainers on each side of the seat but they also have a longer strap and 3 bar slides for adjusting. The male and female end of the buckle are also adjustable allowing you to center the buckle and not have it off to one side.They are long enough to work well with both child seats I've had in the back. And at just over $60 each they are reasonably priced. They are also compatible with shoulder harnesses which is what I will add once my kid outgrows the car seat.

Hey Rob, do you already have the Cessna part for the rear shoulder belts in a 170/2? I can send you an example if you like. I have them installed. You're right that the buckle in the system I posted doesn't accept the BAS-style utility buckle ends, but it's fine for the open-loop style of shoulder harnesses, a la Hooker, etc.

Aircraft Spruce sells shoulder harnesses that will work with this belt, pretty much the hooker style harnesses that I have in the front. The male end of the seat belt buckle slides through the two metal loops on the ends of the harness, then into the female buckle end. The bulkhead behind the rear seats has factory installed nut plates for the use of shoulder harnesses.

Double post

You never told us you got a new plane Pete. You should've started with that! haha.

Sounds like a great plane Pete! Congrats!

What does the Atlee Dodge jumpseat STC call out for the seatbelt attaches? I have the BAS (now Lakevue Aeronautics) jumpseats in my 180, the outboard belts bolt to tabs which must be slid between the bulkhead and the skin and riveted in place. These are apparently Cessna parts, p/n 0711084-15 on the left and -16 on the right. The inboard belts clip to a center attach fitting p/n 711083-1, which bolts down to the stock nutplate in the floor where the stock bench seat attaches.

It seems like you'd want the 3-bar or similar belts so you can adjust where the buckle is on the passenger. On mine, the inboard belts are adjusted way shorter than the outboard belts.

i think i'm due for replacement webbing sometime soon ... i'm guessing mid-70's era
i'm the same as you Rob. kids use and then changing when they get bigger. yes.... they.

swixtt and Rob:
Here's the setup I was talking about. Rob- it goes into the same strap-reinforced nut plate/ bulkhead that you described. I know the hook is OEM Cessna, and I believe the harness hardware is too. I understand they're not too common. It is quite secure in a downward/ forward pull direction, but you can install and remove the rear shoulder harnesses in seconds. It's kind of tight for adults, great for kids- nothing you didn't already know about a 170.

DP, those are cool. I've never seen those before. I like how they are quicky removable.

Yeah, I like the easy-in, easy-out option. My mechanic pulled them out of deep storage!

Those are awesome DP. Wonder if a guy could put a set in a 180? Looks like it would be pretty simple to build.

A1Skinner wrote:Those are awesome DP. Wonder if a guy could put a set in a 180?

My understanding is that all the 4-place, 100-series Cessnas have the reinforcing strap on the bulkhead behind the back seat. So it should work on a 180, at least in theory.

thanks for posting those pics DP!

Good illustrations of the seatbelt attaches for the Dodge seats. I actually just got through looking at the photos Rob posted in the "182 diet plan" thread. He posted them to show off his closed-cell insulation job (BTW that looked great Rob!) but the pics showed the belt arrangement also.

Hey everyone! I'm resurrecting this thread because it has suddenly become very relevant to me. I just recently learned that my 205 has these nut plates as well and I really would like to get some shoulder harnesses for my kids. My plane came with two of those hooks for the front seats, which I then replaced with BAS harnesses.

So, any ideas where I can find two more hooks and four of those attachments that connect the belt to the hook? This looks like this is going to be the big challenge.

Also DP, are you using a Y harness with that like from Wag Aero?

Thanks,
Cory

I've seen those quick-attach shoulder harnesses, but was just now unable to find a source for them.
FWIW I had a set of Aircraft Spruce "style 3A" should harnesses in my last airplane.
They have an attach fitting at the upper end with a single bolt hole,
you can just bolt it to the nutplate in the spar carrythrough.
The lower end is a pair of loops sewn into the webbing, they just slide onto the lap belts.
Sounds cheesy but they worked very well. I liked them.
Cheap too, at less than $75 each. Here's a link.

Good idea. Thanks! I’ll check them out.

Does anyone know if you go with the 3B version of those belts, will the ends work with any normal lap belt buckle? Or do you have to replace them as well? Those two flat pieces that the male end of the seatbelt buckle goes thrift takes up some space. Just not sure if a standard buckle has the space needed to accommodate them.

I'd think the "tongue" on a standard buckle would be too short.
Buckle your buckle, then look to see if there's a good 1/4" or so (maybe more required?) where the strap fittings would go.THat's part of why i chose the 3A style.
The other reason is that you can have the shoulder straps spread out on your lap belt--
having the straps meet in the center at the buckle tend to let the straps rub on your neck,
which I get now with the BAS harnesses in my current airplane.

Cory, you’ll most likely have to buy some new lap belts that will work with the shoulder harnesses. This is the lap belt I had in my 170s front seats that worked with the harness you are talking about. http://m.aircraftspruce.com/catalog/app ... cfer=10604
