It turns out, they're the Dovre mittens, Dovre beeing Tora's home place. I found a couple of them on Ravelry, but no pattern entry, so I added it earlier today. (I don't have details about sizes, gauge and yarn, so if anyone who has the pattern could update it on Ravelry, or leave a comment, so I can do it, it would be nice.)
The mittens were designed by Kirsten Hjort Engum for a design competition in 2000, and have been published in Norsk Huslflid 4- 2007. The pattern, or a kit, can also be bought through Dovre husflidslag ( I guess they're busy sending out patterns at the moment!). I have also found some examples on knitting blogs, here and here.
