Description says this:

Designed by Andrea Cordero Lanza di Montezemolo in 2005. The charges, a scallop shell, Moor’s head, Corbinian’s bear, are taken from his previous coat of arms, used when he was Archbishop of Munich and Freising. Both the Moor’s head and Corbinian’s bear are charges associated with Freising in Bavaria, Germany.

So it should be based on that: https://de.wikipedia.org/wiki/Mohr_(Heraldik)#Der_gekrönte_Mohr_von_Freising_(13._Jahrhundert)
