Thread: Adaptive Front Seats

So this is a long post but a pretty cool mod if you ask me.

Cadillac Developed a seating system that has a series of 10 Air Blatters and uses 8 air pressure sensors that monitor the pressure in the blatter and then readjust every 4 minuets. There are a few different modes as well. There is off, AUTO, and lumbar only. so when the system is in auto, then the system goes to work making the occupant comfportable. lumbar only uses the air blatters in the backrest of the seat to give you your support.

it was a option that added $1,650 to the vehicle way back in 1998-2000.

anyway onto the pics

here is all the parts layed out on the table in Trim


the seat with the bottom cusion ff


back of the seat showing the lumbar


there is the leather off and the blatters mocked up in place


Back of the seat showing the Moudule and the pump for the blatters


the module mocked up in place with the pump




the bottom bags glued in place (using he same arear the GM used for bag movement)




because the Caddy has a different seat cusion design i had to be creative so i took some Last and sewed it into the plastic lumbar plate, so the orignal seat cusion will stick to it


here is the back bags glued in place






i did have to modify the hook and loop of te seat cover so the air lines can get o the correct place




and the money shot. The completed seat with the blatters and the cover reinstalled




adjustable bolsters not only in the backrest but in the bottom cusion.....ya eat your heart out AL7's

Wanna do mine now?

Awesome write-up man, gonna sticky this!

It's really like sitting on a pillow but getting amazing support in the corners

2.) Did you take the foam and all and transfer them to a grand prix seat, or did you put a caddie seat in your Grand prix

Thanks

The bladders, module, and pump came from a 98-2000 Seville STS with the Adptive Seat option. It has to say "AUTO" on the lumbar switch that is located onto the seats. Both the passenger and driver units were pulled from a junkyard

the Foam is the OEM from My Bonneville. But could be adapted to any car with some enginuity.

and the wiring is very simple, its Power, Ground and Ign 3 to make the module activate

Looking forward to someone doing this to GP wooden bench seats. Maybe I won't have to switch to Regal seats to be comfy in my GTP!

P... I was on vacation and didn't it that you had it done. Awesome job as usual. Got both completed?

And yes..when I get there in June, I'm kinda expecting you or I to have a set for the Regal by then. It's going in. I'm missing the Bonneville AL7's still... W body seats (unless you talk 90 turbo car seats) suck monkey butt.

Would Deville seats work as well? The lumbar says auto so I would think that it would work. Here's a pic...

yes, just cut the leather carefully and check for the Bladders
