Front Buckets with Integrated Seatbelts?

[chuckd71]

Those look really nice in brown, and since there are other black things in the car the black plastic bits add needed contrast.
I used some black ones in my convertible. There weren't any brackets to speak of, just the flat bottom rails, so you need to come up with mounts on your own since the floor of the car is anything but flat.

If you scroll down on page 20 and 21 of that thread there are pics of the bottoms, comparison to stock seats and the test fitting. Linking to that thread is just easier than repost pics.

People mentioned searing and mercedes seats, but corsair aren't exactly plug n play and the mercs often have seat controls integrated into door panels. The BMW seats are all-in-one deals. http://www.corvairkid.com/sebring.htm

I would just use Grade 8 bolts in the floor mounts, with some steel plate made into a larger washer to ensure the bolt doesn't pull through the rears in particular. I know the 3/8" hardware is plenty adequate as I've done numerous tests over the years for this exact thing. If anyone is bored, look up FMVSS 207/210 anchorage tests, which is exactly the test for a seat with an integrated shoulder and lap belt.

Chuck,
I looked at your pics at ls1tech, did you shorten the rail on the seats? My Bimmer outside seat rails are longer than the inside.

If you did, does this not reduce the strength of the seat?

Make sure you mount them securely to the floor. You are now asking the seat mounts/bolts to support the weight of the seat AND you in the event of a crash.

i was going to say the same thing. i know dodge trucks had seats like that.

Mine are as well, I didn't cut anything. The rails have mounting holes in them and I lined them up with the thicker parts of the floor (if you look under the car you'll see what I mean, the cross-bracing or whatever). I also had some plate steel from another project that I put under the floor at every bolt, with a few progressively larger washers as well. Got grade 8 stuff from fastenall. With the bolts I used I had to use the holes nearest the ends of the rails to ensure that the seat could still travel it's full range (and these seats have tons of travel).
The only thing I don't like is that the floor of the car slopes in from the door sill rather steeply meaning that unless you can weld you're probably going to mount them slightly more toward the inside than the originals were. I'm about a 1/2 inch over toward the midline when I sit in the driver's seat. Eventually I'll find a pro who can do this so it looks 100% right, but for now I'm satisfied that it's 100% safer than the original seats. That was the whole point of putting these in after all.

I installed bimmer seats in my 69 Pontiac Custom S Vert (A-Body). The driver's seat is 1 inch over midline because the rocker interferes with the outside rail. I can live with it, but it is not perfect.
Did you ever get yours on center? If so, how?

Remember, Bob Johnson always said the top of the seat back should not be over the height of the door!

No, I had some other stuff come up so I'm just going to leave it be for the foreseeable future. Unless I can find a deal on a T56 in the next few months the car is probably going back into the garage for two-three years anyway. If that happens I'll just sell the motor and pick up the project in 2017 sometime. Like you, I can live with it. Messing with the rockers can wait until I can afford a massive restoration.
