Rocking sport seat
I have a 1985 drivers side sport seat that rocks back and forth as I drive in my 635. Any suggestions on how to fix? If I position the seat all the way down, of course there is no problem. Thanks, Ron
Hi
Like you guys i have play in my back rest, my local garage tried to fix it but failed.
It seems the backrest hinge has a half moon cogged plate thingy that is worn away.
Maybe a few spotwelds to build it out and a file could reshape it.
Has anyone tried this?
My skills stop at upholstery. These seats are a delicate work of art.
The 2nd best ever driving seat bar the 911, some magazines say.

Ron's problem sounds like it might be different to the usual backrest problem. The seat base adjuster is fiendishly complicated; it wouldn't take much to get it moving around I expect.
BTW the backrest cog thing has been rebuilt by enterprising folk using MIG weld build-up and grinding, so it can be done. It is a lot of work though. I thought someone had posted pictures of this on this site a while ( a long while, like six years) ago.
cheers

My seat base cracked at the pivot, so I had to remove everything to weld it.
As far as rocking is concerned, I'd imagine if any of the pivot points for the vertical seat adjuster, the part just above the number 1 in this illustration http://bmwfans.info/parts/catalog/E24/C ... _height-2/ has failed, that would cause the seat to "rock" back and forth.
