• a first air guide disposed on the rear side of the cushion member to follow an elastic deformation of the cushion member, the first air guide defining an air passage therein and having an upstream portion and a downstream portion, the upstream portion defining an inlet port through which air is introduced therein, the downstream portion disposed to communicate with the seat back opening of the cushion member;
• a second air guide disposed on the back board in the space, the second air guide defining an air passage therein, the second air guide having an upstream portion defining an inlet port through which air is introduced therein and a downstream portion defining an outlet port;
• and
• a flexible connecting part disposed to flexibly connect the outlet port of the second air guide and the inlet port of the first air guide according to the elastic deformation of the cushion member while defining an air passage between the outlet port of the second air guide and the inlet port of the first air guide.
