In Sweden Batman is called Läderlappen which translate to The Leather Patch. Originally Denmark used this name too where it could be translated as The Leather Flap (as in piece of cloth), taking it directly from the Swedish word, but it has since gone out of style. So yeah, I suppose Sweden should be saying Leather Patch but Leather Flap is so much funnier.
In Norway he was known as Lynvingen, The Lightning Wing, for a while.
