Your Norse examples are actually good. They are known as Spangenhelm and typically are made of 4 panels riveted to metal "straps".
The typical basic Spangen Helm has just the topper and a nose guard, but variations have chainmail hanging from the sides/back, metal "straps" either as verticle straps coming down from the top with a reinforcement behind or almost woven together. Others replace chain/straps with full metal panels. Eye sockets are common on any type of side/backs, and there is sometimes a mix of all of the above.
In fact, one of the most beautiful (actually functional and used) helms (Looks a little like the one on the bottom right) was one that had the standard 4 panel top, with sculpted "eye" guards that included eyebrows and a molded nose. It had cheek plates that came close to the face and solid panels surrounding the sides/back, but overall the panels was fine chainmail that was "stitched" into the rim of the top and under the eye sockets and nose. It was amazing work and I asked the smith that made it. he said he spent 150 hours on making it..
(Note I say functional, as I used to be active in the SCA (Society for Creative Anachronism) and actually hit this guys helm with a "sword" (Ratan Stick) and after the combat asked...
OH, And Just for everyone's common Knowledge. Historically, there is not a single instance where a Norse helm has had Horns on it. The only helms with Horns are Fantasy depictions. Now they were found to sometimes have Wings, but not horns.
