Abstract
An air conditioning unit for introducing air to a surface of a seat back has a first air guide, a second air guide and a flexible connecting part. The first air guide is disposed on a rear side of a cushion member of the seat back to follow an elastic deformation of the cushion member. An upstream portion of the first air guide defines an inlet port. A downstream portion of the first air guide communicates with a seat back opening formed in the cushion member. The second air guide is disposed on a back board, which is located on the rear side of the cushion member with a space. The second air guide has an inlet port at an upstream portion thereof and an outlet port at a downstream end thereof. The flexible connecting part flexibly connects the outlet port of the second air guide and the inlet port of the first air guide.
