4 KudoZ points awarded for this answer. Comment: "Thanks Michael and Ingeborg! Although I needed the answer in a hurry, I never like to grade in a hurry, because you never know what might come up 2-3 days later, and I believe in choosing the best long-term answer, even if it differs from what I went with in the short term. But anyway, looks like this is the only answer that's going to be submitted here. It's a good one though, with an excellent explanation and a reference. I ended up translating the entire phrase, "Streckschnitt im Lordosebereich" as "lordosis support". Many thanks again for your assistance with this quite horrible word."
