First of all thank you for your answer !

I see your point, but ALL orbitals will contribute to the density. So it would 
sum up to a single maximum as it is observe for instance in a experimental 
density plot from a X-Ray experiment. Here you clearly get huge maxima at the 
location of the nucleus and there are no features like the ones seen here. 
And as far as I know from my calculations you also get this structure when 
plotting the total density. So in my eyes this is not a sufficient 
explanation why this structured density makes sense....

Thanks again for your help !
