wenn es um's impressum geht ist es doch sicher ein zusammenhang, wo etwas erklärt wird über den inhalt der webseite, bzw. juristschen kontext. oder ist es ein navigationspunkt?
ich versteh's nicht so ganz wie das aussieht....

I think you've answered your own question. If I've understood this correctly, you have the following:

Impressum

Verantwortung
(name of the company)

Verantwortlich
(Name and title of the "Geschäftsleiter")

I'd suggest the following:

Legal notice (= "Impressum") (There are a wide range of possibilities here. See the KudoZ glossaries, etc.)

Company (= "Verantwortung")
(name of the company)

Contact (= "Verantwortlich")
(Name and title of the "Geschäftsleiter")

The company is legally responsible for the overall website. But if any questions should arise concerning the website, the person who is directly responsible for answering those questions is the contact - in this case, the manager, the CEO, the general manager, the managing director or whatever translation you have for "Geschäftsleiter".

If your website already has a menu item called "Contact" (as is quite common on the Web), then you could write "For questions concerning this website, please contact" instead of just "contact".
