What is a "cozy wing"?

Dear Car Talk | Jun 01, 1995
Dear Tom and Ray:
Jack
RAY: Thanks, Jack. Now if you're right, all we have to do is figure out WHY it's called the cozy wing.
TOM: It could be because when you open the vent window, it makes you feel cozy.
RAY: Or, maybe the guy who invented it was named Cosmo Cozy?
TOM: Obviously, our cozy wing research department is still open. Write to us in care of this newspaper.
