O. Close Germany  

Yes, I think you're talking...
Yes, I think you're talking about the Domani office-chair, an somehow Eames-inspired early 70s piece. Might be by Design-Professor Odo Klose (I'm guessing here), no clues for a manufacturer called Odo Close.
It can be seen in the '77 sci-fi flic Space:1999, alongside with many other pieces of the time.
sorellarium13 has some more screenshots from the film (and the chair), see the link!

Domani Chair from Odo Close in Germany
The Domani chair was clearly inspired by the famous Eames chair. It was manufactured in Germany by a company called Odo Close (not sure if that was also the designer or just the company).
It was featured as the commander's office chair on Space: 1999 and for the second season the Command Center staff chairs were the same chair sans the headrest.
I found the chair in a design book and that's how the Space: 1999 fans knew what it was. It was first in my Space: 1999 Cybrary (including the scanned photo from the book that now appears at Catherine Bujold's Sorellarium):

Here's the scan from the book I found:

There's info on the book that it's in on the Space: 1999 Cybrary, but it's now on CD-ROM and I'd need a Windows machine to read it and I use a Mac, so I can't tell you the book I found it in, but I've never seen it featured anywhere else (it was a book in a series of notable designs for a given year and there was a new book in the series produced each year).
I just happened to look it up and found this page now because it appears in an episode of Two's Company that I rented from Netflix from the fourth season called "The Rolls-Royce" (both the chair with head rest and then two guest chairs across the desk without headrest). It also appeared on The New Avengers (no surprise since Keith Wilson was the production designer after Space: 1999 ended) in the episode where Purdy's fiance reappears, and it's featured in an episode of Doctor Who from the same period (but this one with white upholstery on an all-white body shell).
It's a great design. I wish they still made it. I've never seen one for sale and I suspect by now the pneumatic adjusters are shot and probably the fiberglass body shells are cracked, scratched, and so on, but you never know.
Good luck in your search.

Hello,
thank you for your...
Hello,
thank you for your help. I think I've seen this chair many years ago in Germany at somebody's home my parents visited. As I recall the seat was black actualy.
Can you give me the name of the book somehow if you can open the cd? Or make me a copy of the cd so I can read it at my pc?
Hope to find one of these in the future.
Thanx again for the replies...
