Looking for recommendations-Please

I'll be taking Teeko on a fairly long car ride soon. (roughly 10 hours, could be more depending on the weather conditions) I was wondering if someone could recommend a good seat belt for him, please?

One where he would be able to stand up, lay on his pillow (the whole back seat will be his), go to each window if he wants, one where he is fairly secure but has a little room for movement but can move a little. It can be dangerous because we have alot of snow and it's icy so I want him to be safe.

He weighs roughly 22-23 pounds.

Thanks :)

When we rode in her car, it worked nicely with a harness!
