Hello Antonio, Sven,

thanks for your comments. With your help I could set it up. The mistake 
was in fact the ip-address on bat0.

I removed all IP addresses and set them to the bridge. That worked !

For those who might run into the same problem, here is the correct setup:
http://www.radtke.eu/tmp/Leitzberg-Mesh-corrected.gif

But a question is remaining: once the mesh was running, I wanted to turn 
on enrcyption but this seems not working in ad-hoc mode with OpenWRT . 
If I select Access Point mode for wlan0 the WPA2 encryption works....but 
this is not supported with batman-adv since the wifis need to run in 
ad-hoc mode. Any hint for this if I want to run the mesh encrypted ?

P.D. Same happens if I run IEEE 802.11s mode (without batman-adv). Works 
well but encryption setting doesn't work.

Best regards, Stefan
